Study Finds: Scientists Built Cancer Kill Switch That Turns On With Flash Of Light

Photonics influences cell behavior by using light. Technocrats have discovered that many cells, or genetically modified cells, express light-sensitive proteins (opsins, rhodopsins) that open or close ion channels when illuminated, changing membrane potential and firing patterns. In neurons, this directly controls excitability, synaptic transmission, and network dynamics on millisecond timescales. ⁃ Patrick Wood, Editor.

Cancer has a dirty trick: it can put itself to sleep. When tumor cells slip into a kind of biological hibernation, they become hard to kill, shrugging off treatment and lying low until conditions improve, then waking up and bringing the disease back. For decades, researchers have struggled to shut down this hiding strategy without causing serious harm elsewhere in the body. A team in Switzerland has now built a molecule that flips on and off with flashes of light, giving scientists a precise new way to probe, and possibly disrupt, the way sleeping cancer cells hide.

Behind this cellular sleep state, at least in certain cancers, sits a protein called the glucocorticoid receptor, a sensor inside cells that reacts to stress hormones. When it switches on, it can push cancer cells, especially in some solid tumors such as lung cancer, into a drug-resistant, dormant state. The obvious fix would be to destroy the receptor outright, but there is a catch: the same receptor does important jobs all over the body, including calming inflammation. Removing it everywhere would cause real damage. What was needed was a way to hit the receptor inside a tumor and leave the rest of the body alone.

That is what the team set out to build. Their solution, described in the journal Proceedings of the National Academy of Sciences, is a class of molecules called photoPROTACs: drug-like compounds engineered to destroy the stress hormone receptor, but only when a specific color of light switches them on. Shine the right light on them, and they go to work. Keep them in the dark, and they stay idle.

A Kill Switch for a Stress Hormone Receptor

It helps to know what a PROTAC is. A PROTAC is a molecule that grabs onto a specific protein inside a cell and tags it for destruction by the cell’s own waste-disposal system. It works like slapping a “delete me” sticky note on an unwanted protein. PROTACs have stirred huge excitement in medicine because they can eliminate proteins that ordinary drugs cannot touch.

Conventional PROTACs have a problem: they are always on. Once taken, they work throughout the entire body, destroying their target in cancer cells and healthy cells alike. For a receptor this important to normal health, that is a dealbreaker.

To get around it, the team embedded a light-sensitive part directly into the PROTAC molecule. By adding a chemical structure that physically changes shape depending on the wavelength of light hitting it, they created a molecular switch. In one shape, called the E-form, the molecule has the right geometry to do its job and destroy the receptor. In the other, the Z-form, it bends into a configuration that leaves it far less active. The switch runs both ways: one wavelength turns the molecule on, another turns it off.

Building the Light-Activated Cancer Switch

Researchers built and tested several versions of these light-switchable molecules, hunting for the best balance of stability and responsiveness. Two lead compounds, KH-5-306 and KH-5-309, stood out. Both flipped almost completely between their active and inactive shapes under different wavelengths of light and showed no signs of wearing out after repeated exposure.

Inside cells, both compounds destroyed the stress hormone receptor in their active E-form at very low doses. Switched to the inactive Z-form, the effect dropped sharply, though the inactive form still held on to some activity. Because the Z-form naturally drifts back toward the active E-form at body temperature, researchers kept it locked in place during experiments by hitting the cells with brief bursts of ultraviolet light every 30 minutes, a lab-only workaround they confirmed did not harm the cells or disturb the biology under study, and not a method meant for patients.

Additional tests confirmed the receptor destruction ran through the cell’s normal disposal machinery: when a separate inhibitor blocked that machinery, the photoPROTACs stopped working. The compounds also left a closely related receptor alone, even at higher doses, a sign the molecules were hitting their intended target and not damaging look-alikes. And the effect proved temporary. When the active compound was washed away after 12 hours, receptor levels started climbing back within 24.

Waking Up Sleeping Lung Cancer Cells

With the chemistry checked, researchers moved to a test closer to real medicine. They took human lung cancer cells and treated them with dexamethasone, a common steroid that switches on the glucocorticoid receptor and nudges these cells into a dormancy-like state. That setup mirrors a real problem: dexamethasone is routinely given to cancer patients to manage inflammation and treatment side effects, yet it may quietly push tumor cells toward this drug-resistant sleep.

After confirming that dexamethasone triggered the expected dormancy response, the team tested whether the lead photoPROTAC, KH-5-309, could reverse it. Cells treated with the active E-form saw the dormancy-linked gene activity roll back toward normal, and a sweep across thousands of genes confirmed the shift toward a more active state. By contrast, the inactive Z-form left those genes essentially untouched, behaving in this experiment as a neutral control on par with no treatment at all.

What’s Next for Light-Controlled Cancer Treatment

Researchers are candid about the limits. The biggest obstacle to reaching real patients is the kind of light involved. The wavelengths that switch these compounds on do not travel far into living tissue, so the current version could not reach a tumor buried deep in the body. Developing compounds that respond to longer, redder wavelengths, such as near-infrared light that penetrates tissue more deeply, is a key goal for future work rather than a solved problem.

For now, the strongest promise is in the lab: studying cancer biology in cell cultures, tissue slices, and lab-grown miniature organs called organoids, where light can be aimed precisely and repeatedly. Those tools give scientists a way to study how stress hormone signaling drives cancer behavior that existing drugs cannot match.

Cancer’s ability to play dead has long been one of the most frustrating barriers to lasting cures. This is early-stage work, years from any use in the clinic, but a well-aimed flash of light that disrupts cancer’s hiding strategy is the kind of proof-of-concept result that hands researchers a fresh grip on a stubborn problem.

Balancing Equity and Efficiency with Atkinson’s Welfare

24 June 2026 at 14:39

In the evolving landscape of global water resource management, addressing the persistent tension between equitable distribution and cooperative efficiency remains a paramount challenge. A pioneering study recently published in Nature Water introduces an innovative Atkinson social welfare function (SWF)-based framework that operationalizes distributive equity alongside systemic efficiency within transboundary water systems. By embedding equity explicitly as a normative design criterion, this framework leverages an adjustable inequality aversion parameter, providing policymakers with a powerful tool to balance social justice with optimal resource use.

At the heart of this advancement lies the mathematical backbone of the Atkinson SWF, a function well-regarded for its flexibility in capturing societal preferences for inequality reduction. The framework transforms equity from a nebulous ideal into a quantifiable, adjustable dimension directly integrated within multi-objective optimization. Applied to the Zambezi Watercourse—a complex shared basin impacting multiple countries—the model reveals that introducing inequality aversion yields only modest reductions in total hydropower output, around 1–2.7%, while significantly lowering disparities in country-level generation by 3 to 8 points on the Atkinson index.

This nuance is crucial because natural constraints such as water availability and turbine capacity inherently limit the scope for redistributing hydropower output to improve equity. Instead, the model shows that inequality aversion primarily affects firm generation capacity, where Zimbabwe and Zambia experience substantial percentage increases during critical periods, reflecting strategic operational shifts. Mozambique’s generation remains relatively stable. Such findings underscore a pragmatic approach to equity: rather than static allocation, operational strategies can target support during vulnerable drought conditions, effectively marrying resilience with justice.

Importantly, the concave utility assumption underlying inequality aversion parallels risk aversion concepts in economic theory. This alignment suggests that what often appears as an efficiency sacrifice in pursuit of equity may, in fact, represent a system more robust to uncertainty and stressors. In water resource contexts marked by ecological variability and competing demands, this insight reframes equity not as a zero-sum trade-off but as integral to sustainable cooperation.

A key innovation of the framework is its dynamic adaptiveness during optimization, eschewing rigid allocation rules or static weightings. For instance, when factoring in floating photovoltaic (FPV) investments alongside traditional hydropower, Mozambique assumes the full cost of preserving near-natural environmental flows in its delta—sacrificing 41% of hydropower generation and facing frequent low-output periods. Yet, this environmental stewardship shifts investment priorities away from Zambia to Mozambique without requiring prior distributional knowledge, thereby reducing inequality by 25 Atkinson index points with a modest overall production trade-off of 4.2%. This responsiveness is a critical advancement for transboundary water management, where power dynamics and environmental conditions are perpetually in flux.

The study deliberately calibrates its inequality aversion parameter, epsilon (ϵ), at 2—a level representing strong equity preference—to demonstrate the framework’s capabilities. However, it recognizes stakeholder perspectives may differ widely. Rather than treating epsilon as a technical constant, the authors advocate viewing it as a parameter for deliberation, surfacing explicit negotiation choices among diverse actors. Structured choice experiments could translate complex mathematical trade-offs into intuitively understandable options, enabling stakeholders to reveal implicit equity preferences through participatory processes. This approach dovetails with the multi-objective optimization’s Pareto frontier, which transparently spans the spectrum from maximal efficiency to maximal equity, thus facilitating informed trade-offs.

The researchers embed a normative assumption in their baseline welfare function: treating each country as an equally weighted actor, reflecting sovereignty principles inherent in international water law and institutional arrangements like ZAMCOM, the Zambezi Watercourse Commission. This aligns with the ‘one state, one vote’ doctrine, appropriate for interstate governance frameworks. Yet, the team acknowledges the normative and practical implications of population-weighted alternatives. Incorporating population in the welfare aggregate could, for example, prioritize individual welfare across riparian states rather than equal state-level standing. Such distinctions have profound implications—especially in basins like the Zambezi where the most populous country, Mozambique, has the lowest per-capita hydropower generation.

Extending the framework to a population-weighted SWF or a per-capita welfare input introduces normative choices about justice, as these measure equity through fundamentally different lenses: aggregate human welfare versus national sovereignty. In scenarios where population rankings and per-capita generation rankings conflict, these alternatives may pull policy preferences in divergent directions, underscoring the need for societal dialogue to resolve such trade-offs.

While the study focuses on interstate equity, it also addresses the crucial gap of intrastate disparities, which country-level metrics risk obscuring. Implementing the framework at subnational scales would necessitate coupling basin-wide hydrological models with detailed power system dispatch simulations and geospatial electrification mapping. Though technically complex, such integration promises to capture localized inequalities in access and generation more effectively. Preliminary attempts, such as those conducted in Ghana, employ inequity metrics like the Gini index but lack Atkinson’s adjustable inequality aversion—an essential feature for nuanced policy negotiation. The authors argue that their SWF framework offers scalable advantages for applying distributive justice across regional or even community scales, especially in data-scarce, transboundary environments.

A particularly thought-provoking question arises around accommodating group-specific inequality aversion across demographic or vulnerability categories—such as gender-differentiated impacts or subregional disparities within countries. From a methodological standpoint, the study identifies significant hurdles. Introducing distinct epsilon parameters for multiple groups compromises the anonymity and Pigou-Dalton consistency properties fundamental to welfare economics and adds layers of unquantifiable normative complexity. Instead, the authors advocate maintaining a single inequality aversion parameter, deferring subgroup analyses to disaggregated data where possible and allowing these insights to inform participatory negotiations.

Complementary approaches, including incorporation of needs-referenced thresholds consistent with prioritarian ethics, face challenges tied to the Atkinson function’s strict positivity constraints and the difficulty of justifying group-specific thresholds beyond narrowly defined legal or vulnerability classifications. Ultimately, the study emphasizes that the framework’s power lies in making equity visible and operationally relevant, rather than complicating aggregation with layered value parameters.

Beyond hydropower and water management, this Atkinson SWF-based approach holds broader applicability. Many resource allocation challenges characterized by monotonic, concave utilities—such as renewable energy deployment, biodiversity conservation, or climate adaptation finance—stand to benefit from formalized equity-efficiency trade-offs. Threshold effects or objectives with increasing returns require separate treatment within multi-objective optimization, but many relevant environmental and social goals fit the concavity assumption well.

As climate change intensifies variability in precipitation and water availability, the necessity of cooperative frameworks balancing equity and efficiency becomes ever more urgent to prevent breakdowns in international water agreements. By operationalizing the principle of ‘equitable and reasonable utilization,’ this research translates normative international water law doctrines into tangible, evidence-based decision tools that directly relate to real-world human welfare and environmental sustainability outcomes. The Atkinson SWF, with its adaptable inequality aversion and capacity for participatory negotiation, emerges as a promising lynchpin for future transboundary water governance.

In conclusion, this study marks a notable advance towards integrating distributive justice within multi-actor optimization models for shared water systems. It demonstrates how explicit normative assumptions can coexist with rigorous technical analysis to produce outcomes that are both efficient and equitable. The dynamic responsiveness embedded in the framework addresses the complexity and uncertainty of water sharing arrangements, facilitating adaptive cooperation even as political and climatic conditions evolve. This balanced approach, supported by empirical application to the Zambezi basin, could serve as a blueprint for operationalizing equity in other transboundary resource settings worldwide.

As demands on common-pool resources mount, such integrative approaches will be indispensable for sustaining long-term cooperation. By linking sophisticated welfare economics with participatory policy processes and cutting-edge water system simulations, this research provides both the theoretical foundation and practical pathway to reconcile competing values on the international stage. The Atkinson SWF-based equity framework thus represents a crucial step towards more just, resilient, and sustainable shared water futures.

GitHub Actions hardens checkout security to block ‘pwn request’ attacks

23 June 2026 at 00:43

Stung by a surge in cyberattacks that have run amok in developer environments, GitHub has strengthened the security of actions/checkout to block ‘pwn request’ attacks that exploit insecure use of the pull_request_target workflow trigger to run an attacker’s code with the workflow’s full privileges.

Announced on June 18, actions/checkout v7 now automatically blocks and fails workflows when used inside pull_request_target or workflow_run events when attempting to fetch unreviewed fork pull request code.

From now on, the only away around these checks will be for developers to implement an opt out by adding an explicit allow-unsafe-pr-checkout to actions/checkout, GitHub said in its V7 changelog.

The change signals the beginning of a new ‘secure by default’ era in which security will be defined by the GitHub system rather than being left to discretion of developers. As part of that effort, on July 16, the new defaults will be backported to all supported major versions.

“Workflows pinned to a floating major tag (e.g., actions/checkout@v4) will automatically pick up the change. Workflows pinned to a specific SHA, minor, or patch version aren’t affected by the backport and will need to upgrade using Dependabot or through established upgrade processes,” GitHub explained.

However, because pwn request attacks can happen in other ways, “further hardening of additional events may be explored in future releases,” the changelog added.

Blind spot

If there’s a criticism that can be levelled at GitHub over this, it’s that it has taken so long to address a weakness that’s been known about for years.

The issue is with GitHub Actions, which allows triggers to run workflows, including pull_request, which processes third-party forks without giving access to secrets such as API keys, service tokens, and credentials. The downside is that this restriction prevents some automations from working, which is why developers turn to an alternative trigger, pull_request_target, which grants the required access.

At some point, attackers realized that where pull_request_target was configured carelessly with actions/checkout to pull in untrusted fork code, it offered a back door into repositories and their secrets.

In other words, the weakness in pull_request_target isn’t the trigger itself, which is legitimate and secure when correctly used, but in its  incorrect use. As GitHub’s changelog puts it: “Checking out the head of an unreviewed pull request from a fork inside one of these workflows typically lets attacker-controlled code execute with the workflow’s full privileges.”

The arrival of actions/checkout v7, however, should make this harder, automatically blocking risky workflows regardless of their configuration.

Unfortunately, a lot of damage has already been done. Open source repositories have recently come under sustained attacks from the TeamPCP hacking group, using a variety of techniques, including pwn requests.

A notable example was its attack last month, which compromised 170 node package manager (npm) packages, including the TanStack Router ecosystem, thanks to a pwn request exploit. Embarrassingly, in a separate incident not involving a pwn request, GitHub itself was breached and the attackers exfiltrated source code from around 3,800 of the company’s internal repositories.

Better late than never, GitHub has sprung into action, plotting a series of security reforms on the platform, including, earlier this month, limiting automatic install script execution in npm.

South America’s Rapid Warming During Last Deglaciation

20 June 2026 at 03:13

In a groundbreaking new study published in Nature Communications, researchers Ampuero, Stríkis, Meckler, and colleagues have unveiled compelling evidence of rapid warming in South America during the last deglaciation, a period roughly spanning from 20,000 to 10,000 years ago. This revelation not only reshapes our understanding of ancient climate dynamics in the Southern Hemisphere but also provides critical insights relevant to modern climate change scenarios. The study harnesses a suite of advanced geochemical proxies and high-resolution sediment analyses to reconstruct past temperature variations with unprecedented precision, shedding light on the complex interplay of atmospheric and oceanic processes that drove rapid temperature shifts during this critical juncture in Earth’s climate history.

The last deglaciation marks the transition from the Last Glacial Maximum (LGM), characterized by extensive ice sheets and colder global temperatures, to the relatively warmer Holocene epoch. While the general timeline of global warming during this period has been well documented, the rate and regional variability of temperature changes in South America remained less clear. This research addresses that gap by focusing on paleoclimatic archives from the Andes and adjacent lowlands, areas particularly sensitive to past climate fluctuations due to their unique topography and atmospheric circulation patterns. The team’s integration of isotopic measurements, sediment core analyses, and climate modeling has allowed them to track rapid temperature increases occurring in discrete pulses rather than gradual trends.

One of the study’s central findings is that the warming episodes in South America during the deglaciation were not synchronous with the Northern Hemisphere, suggesting a nuanced asynchronous behavior in global climate systems. This asynchrony challenges prevailing assumptions derived from mid-latitude and polar records predominantly from the Northern Hemisphere. The evidence points to a scenario where atmospheric teleconnections, influenced by shifts in the Intertropical Convergence Zone (ITCZ), played a vital role in redistributing heat between hemispheres. Changes in the ITCZ’s position and intensity appear to have triggered alterations in monsoonal patterns and precipitation regimes across tropical and subtropical South America, thereby accelerating warming trends.

Delving deeper into the proxies used, the research team employed oxygen isotope ratios (δ18O) from speleothems and lacustrine carbonate deposits, alongside organic biomarkers preserved in lake sediments. These proxies are invaluable for reconstructing past temperature and hydrological conditions. Their fine temporal resolution enabled the team to detect rapid warming events occurring over mere decades to centuries, contrasting starkly with previously assumed millennial-scale trends. This high-resolution data challenges the paradigm that post-glacial warming was a slow and steady process, underscoring the climate system’s capacity for abrupt state shifts driven by complex feedback mechanisms.

The study posits that these rapid warming events are linked to deglacial reductions in ice volume combined with rising greenhouse gas concentrations, which collectively enhanced atmospheric temperatures. However, the mechanisms responsible for regional heterogeneity in warming intensity remain a frontier of research. The authors hypothesize that the interplay between the South Atlantic Ocean’s temperature gradients and the Andes’ orographic effects created microclimates that either amplified or moderated warming signals locally. These insights highlight the intricacies of Earth’s cryosphere-atmosphere interactions, emphasizing that regional response to global forcings can diverge dramatically.

Crucially, the study carries significant implications for understanding future climate trajectories. The past rapid warming episodes provide analogs for the rate and spatial distribution of modern anthropogenic warming, especially in mountainous and tropical regions. Given that South America supports critical biodiversity hotspots and large human populations dependent on glacial-fed water resources, these findings raise concerns about the vulnerability of such systems to contemporary climate disruptions. They also stress the importance of refining climate models to incorporate regional heterogeneities and abrupt transitions observed in past climates to improve future predictions.

The methodologies applied in this study exemplify advancements in paleoclimatology. High-precision radiometric dating techniques, including uranium-thorium series and radiocarbon calibrations, ensured robust chronological frameworks. Simultaneously, the use of compound-specific isotope analyses allowed disentanglement of temperature signals from confounding hydrological changes. By merging empirical data with state-of-the-art climate model simulations, the research provides a comprehensive narrative that integrates proxy evidence with theoretical climate dynamics, fostering an interdisciplinary understanding crucial for reconstructing past climates.

This investigation also revisits the role of Southern Hemisphere westerly winds during glacial terminations. These winds, known to influence oceanic upwelling and atmospheric moisture transport, appear to have shifted latitudinally and intensified during warming intervals, enhancing the carbon cycle feedback through increased ocean-atmosphere exchange. Such shifts would have profound implications for regional precipitation and temperature patterns, echoing the complex feedback loops that amplify climate variability. The interplay between atmospheric circulation changes and deglacial warming elucidated in this work refines our grasp of the mechanisms driving rapid climate shifts in South America.

The detailed record of warming patterns obtained from Andean ice cores and sediment cores also reveals that local climate responses were amplified by feedback mechanisms related to vegetation changes and soil moisture dynamics. As temperatures rose, altered precipitation regimes induced shifts in ecosystem composition and land surface properties, which in turn influenced regional albedo and evapotranspiration rates. These biophysical feedbacks likely intensified warming pulses, creating nonlinear climate responses that challenge the linear projections often found in simplified models. The study’s recognition of these processes underscores the need to consider feedback loops when analyzing both past and future climate events.

Furthermore, the research highlights the influence of meltwater pulses originating from retreating glaciers on ocean circulation patterns in the South Atlantic, which may have contributed to abrupt changes in the Atlantic Meridional Overturning Circulation (AMOC). These oceanic perturbations would have cascaded into atmospheric circulation anomalies, further modulating temperature regimes. The integration of paleohydrological and oceanographic data thus provides a multidimensional perspective on how coupled ocean-atmosphere-cryosphere systems orchestrated climate variability during the last deglaciation.

The findings provoke new questions about thresholds and tipping points in paleoclimatic systems. The demonstrated rapid warming episodes suggest that even small incremental increases in external forcings can trigger disproportionately large climate responses once feedbacks are engaged. Such insights are vital for modern climate science, particularly in understanding the potential for abrupt, nonlinear climate transitions under ongoing anthropogenic pressures. By decoding the clues encoded in South America’s geological record, the study enhances our ability to forecast and mitigate the risks associated with rapid climatic changes.

Notably, this work emphasizes the importance of cross-continental and hemispheric comparisons in paleoclimatic studies. By juxtaposing South American data with Northern Hemisphere and Antarctic records, the researchers have contextualized regional warming events within the broader global climate narrative. This comparative approach reveals asynchronous yet interconnected patterns of deglacial warming, challenging simplistic notions of uniform climate shifts and advocating for more intricate, region-specific assessments of past climate dynamics.

In conclusion, the study by Ampuero et al. represents a significant stride in reconstructing past climate change with regional fidelity and temporal precision. Their identification of rapid warming intervals during the last deglaciation in South America not only enriches the scientific understanding of glacial-interglacial transitions but also provides vital lessons for the present and future. The intricate linkages among atmospheric circulation, oceanic processes, and terrestrial feedbacks revealed by this study underscore the intricacy of Earth’s climate system and the urgency of addressing rapid environmental changes from a holistic perspective. Future research inspired by this work will undoubtedly deepen insights into the mechanisms of abrupt climate change and help refine predictive climate models essential for safeguarding vulnerable ecosystems and societies.

Microsoft broke some OLE automations with latest Windows update

19 June 2026 at 15:39

Microsoft Office users may find that some of their applications are failing to open when called on by third-party applications. It’s an issue that has emerged after the latest round of Microsoft updates.

The problem affects Word, Excel, and other Office applications opened from third-party offerings including CCH Engagement, Workpaper Manager, Zotero, or dental office software such as Dentrix or Softdent.

The update issued on June 9 appears to have triggered problems with the OLE automation that these third-party applications use to interact with Office. Users have reported that files are failing to open, with no error message indicating what has gone wrong,

According to one Windows user forum, the issue is particularly frustrating because of this lack of error message. As one user put it, “‘Word won’t open from our workpaper system’ is functionally the same as ‘Word is broken.’ To an administrator, the difference determines whether the next hour is spent repairing Office, rolling back Windows, calling a line-of-business vendor, or opening a Microsoft support case.”

Microsoft has said that it is aware of the issue and is working towards a resolution.

Deleting mystery file

The company is also looking to fix a minor issue that has emerged from this latest round of updates: Users are finding that when items are deleted, the confirmation dialog box displays the internal Recycle Bin file name (for example, $Rxxxxx.ext) instead of the original file name. However, Microsoft stressed that in the Recycle Bin, the item still appears with its original name.

How to bring the best Android 17 features to any Android phone today

19 June 2026 at 10:45

Google’s latest and greatest Android version is officially now out in the world and available — but if you’re using any phone other than a Pixel, that doesn’t mean much for you just yet.

The reason why is simple: Despite Google officially launching Android 17 and starting to send it out to Android phone-owners this week, it’s up to each individual device-maker to process the software and deliver it to its customers. And outside of Google itself, unfortunately, most Android device-makers are exasperatingly unreliable about making that happen — some of ’em to almost comically bad extremes (insert exaggerated sigh here).

Hold the phone, though — ’cause there is some good news here: While we can’t force any Android phone-maker to start treating software support as a priority, we can get creative and find ways to bring interesting new Android features to devices running older Android versions. In fact, all four of the Android 17 features I called out earlier this week can be emulated on any Android phone this instant. All it takes is a teensy pinch of inspiration and a dash of tenacity — and, of course, the right roadmap to make it all come together.

The tenacity’s on you, but if you’re game, I’ve got your roadmap ready. Here’s exactly how to enjoy a similar sort of Android-17-style sorcery on whatever phone you’re using right now — as far as some of the more surface-level highlights, at least — without having the actual Android 17 upgrade in front of you.

[Get fresh Android tips in your inbox with my free Android Intelligence newsletter — one new and useful thing to try every Friday!]

Android 17 feature #1: Bubbles multitasking magic

The most shape-shifting Android 17 of all, without a doubt, is Bubbles — a snazzy new way to turn any app into a floating, collapsible window that’s readily available for on-demand access but also out of your hair when you aren’t actively using it.

Android 17’s Bubbles multitasking system in action.

JR Raphael, Foundry

I wrote about Bubbles and ways to achieve similar feats just a few months back. It’s surprisingly easy to accomplish, even without Android 17 in the picture.

Look over this list of crafty Bubbles-bringing workarounds and see which makes the most sense for you. One way or another, you’ll find yourself facing a fantastic new option for multitasking anytime you want it — no waiting or out-of-reach upgrades required.

Android 17 feature #2: Smarter location access

Our next Android 17 addition is a little trickier to emulate without the actual operating system update in the equation. But fear not, for this is Android — and when there’s a will, there’s a way.

The feature of which we speak is an expansion of Android’s framework for how apps can access your location. It’s a two-parter: First, whenever any app is accessing your location, you’ll now see a blue dot appear in the upper-right corner of your screen — and if you swipe down once from the top of your screen to open your notification panel, you can actually tap on the location icon that appears in its place to get detailed info about exactly which app or apps are involved. Second, when an app asks to access your precise location, Android 17 adds in the option to allow such access only temporarily — for that one brief moment and purpose — without giving the app permanent permission for ongoing use.

The second part, unfortunately, is challenging to achieve without Android 17 being present. But the first part is something we can make happen with a sliver of creative zest.

The trick revolves around a classic third-party app called Privacy Dashboard. Privacy Dashboard came about back in the Android 12 era, when Google first introduced a full-fledged privacy dashboard into Android and certain devices were lagging behind and taking too long to adopt it.

With Android 12 now being five years old, the app hasn’t had much need in recent years — until now. Interestingly enough, the ability to see full details about ongoing location access and then tap to adjust the associated app’s settings is something Privacy Dashboard has long offered. And it’s consequently a great way to bring that newfound native ability from Android 17 onto a device running an older Android version.

The catch is that because of the limited need for the app all this time, it’s no longer being actively developed — and as a result, if you hadn’t previously downloaded it, the Play Store will probably give you an error saying it’s made for an older Android version and can’t be installed on your device.

It will still work, though, and it’s perfectly functional and effective.

Provided you’re comfortable and that this won’t violate any of your company-associated policies, you can download the original verified Privacy Dashboard app package from my own personal Drive storage. I saved it using the Google Files file manager and then uploaded it directly to Drive. It’s quite literally the same exact app you’d get from the Play Store, if the Play Store would let you download it — and while I wouldn’t often advise installing apps from unknown sources, I don’t exactly consider myself to be “unknown” (most of the time). So as long as you share that same trust, you can grab the app from me and put it on any device you want.

Once you get the app installed and give it the permissions it needs to operate, open ‘er up and tap the “App Settings” options on its main screen. Tap the line that says “Indicator Customization,” beneath “Privacy Indicators,” then flip the toggle next to “Click action” into the on and active position.

Aaaaand, that’s it: Anytime an app is accessing your location, you’ll see a green location icon appear in the upper-right corner of your screen. And tapping it will take you to the system-level timeline of exactly which apps have accessed your location recently, for added context.

Privacy Dashboard was ahead of its time with its Android-17-reminiscent location access indicators.

JR Raphael, Foundry

Before you install Privacy Dashboard, you might also want to try just opening an app that you know accesses your location — like Google Maps — and seeing what, if any, indicator appears in the corner of your screen and if you can tap it. While that ability is technically associated with Android 17, it was actually included in an earlier Android quarterly update, and it’s possible your device may already have that piece of the puzzle in place even if it isn’t yet running Android 17.

Android 17 feature #3: More dynamic dark mode

Android’s dark mode is better than ever as of Android 17, with a nifty new way to force each and every app to respect your device-wide dark mode setting and adjust its interface to a less glary look — even if it doesn’t technically support the option.

Android 17 dark theme expanded
Dark mode in Android 17 includes a useful new “Expanded” option.

JR Raphael, Foundry

Well, get this: If your phone’s Android software is reasonably recent, it’s entirely possible you can unlock the very same function by adjusting a few out-of-sight system settings.

Try this:

  • First, you’ll need enable Android’s developer options, if you haven’t done that previously.
    • That’s a special, typically hidden section of Android’s system settings with all sorts of advanced options that aren’t typically intended for average phone-usin’ folk to futz around with.
    • There’s no risk to you or your phone with enabling ’em, and as long as you follow the instructions here exactly and enable only the one single setting we’re about to go over, it’s actually quite easy. (It’s also quite easy to undo, if you ever decide you aren’t into it and want to go back.) But we are pokin’ around in an area of Android that’s meant mostly for developers, and if you veer off-course and mess with the wrong setting, you could make a mess — so follow the steps closely, capisce?
  • The process for enabling Android’s developer options may sound strange, but I swear it works: Head into the “About phone” section of your system settings, tap “Software information,” if needed, then find the line that says “Build number.” Tap your finger on it seven times, then enter your PIN or password, if prompted, and confirm that you want to activate the developer options.
  • Now, go back to your main settings screen and either tap on the “Developer options” that appears within that list or tap “System” and then tap “Developer options” from there.
  • Scroll down through that section until you see an option called “Force Dark mode.” Flip the toggle next to it.

Android’s developer settings holds the secret to Android-17-style “Extended” dark mode, even on older Android versions.

JR Raphael, Foundry

And there ya have it: You should now be able to open any app, even if it doesn’t officially support dark mode, and see it shift into a darkened state whenever you have dark mode enabled at the system level. 

Easy peasy, no?

Android 17 feature #4: A more comfy all-around view

Our final Android 17 feature is a saucy little somethin’ called Comfort View. It applies a softer, pastel-oriented filter to your display with automatic adjustments based on your current viewing environment in order to make your screen easier on the eyes.

If you’re using a Samsung device, you may already have something similar in place even with an older Android version. Look in the Display section of your system settings and see if you see something called “Adaptive color tone,” then try activating it if it’s there — and/or look for “Screen mode” and play around with some of the settings in that area to see vaguely similar sorts of adjustments. It isn’t quite as intelligent or automatic as the new incoming Android-level equivalent, but it’s a start!

In any other scenario — or if you just want more nuance and control, even with a Samsung gizmo — grab an app called Twilight. It’ll let you tweak all sorts of specifics about the appearance of your screen, and while it’s presented mostly for nighttime optimization, you can use those same controls to create your own custom modes for any scenario imaginable.

Were dinosaurs doomed before the asteroid hit?

18 June 2026 at 12:00

Around 66 million years ago, an asteroid wiped out 75% of the species on Earth. This event caused the extinction of all dinosaurs except birds, referred to as non-avian dinosaurs. However, an open question in paleontology is whether the dinosaurs were already declining before the asteroid hit. Many scientists think that around 5 to 10 million years before the extinction event, dinosaurs became less biologically diverse across America, making them more prone to extinction. 

To investigate this hypothesis, scientists recently revisited fossils in a rock layer from the end of the dinosaur era that previous researchers had incorrectly dated. The bulk of the fossils from this period had previously been collected from a different section of rocks called the Hell Creek Formation in Montana. These researchers studied a rock layer in New Mexico that is exposed to the surface, known as the Naashoibito Member. It’s approximately 30 meters (about 100 feet) thick and formed from ancient river sediments. 

To determine when the Naashoibito Member formed, the scientists measured the decay of radioactive elements within its mineral grains over time, a technique called radiometric dating. The scientist reasoned that these mineral grains must have crystallized before being transported and incorporated into the Naashoibito Member, so their youngest ages should provide a maximum depositional age. 

They determined the ages of 1,046 crystals of the mineral feldspar from 2 dinosaur-bearing rock layers in the Naashoibito Member. Based on these ages, the researchers found that a sandstone within 5 meters (about 16 feet) of the lowest boundary of the Naashoibito Member must be younger than 66.9 million years old. They found that the other layer, which is around 3.5 meters (11 feet) from the base of the lowest boundary, must be younger than 66.4 million years old. These age ranges indicated that the sandstone contains dinosaur fossils formed 400,000 years before their extinction.

Next, the researchers measured the direction of magnetic minerals inside the rocks, using a practice called magnetostratigraphy. The direction of these minerals indicates where Earth’s magnetic field was pointing at that time. Scientists have shown that the Earth’s magnetic field has flipped multiple times over Earth’s history, so they can use these magnetic signals to create a timescale for when the sediments formed. 

The researchers wanted to determine whether the magnetic minerals were lined up in a direction like today, called normal polarity, or the opposite, called reverse polarity. The researchers found one rock layer with normal polarity at the base of the Naashoibito Member, and one with reverse polarity in the upper part of the Naashoibito Member. These magnetic field directions lined up with 2 known polarity intervals over a timeline that matched the feldspar dates. Together, these data demonstrated that the Naashoibito Member formed at the end of the dinosaur era, around the same time as the Hell Creek Formation.

Next, the researchers wanted to test whether non-avian dinosaurs maintained their diversity across different regions of Western North America during this time period. They compared fossil patterns from locations across North America using statistical grouping methods that determine how similar or different their environments were. They found that temperature, rather than geographical location alone, was the best predictor of diversity at the extinction event. 

The team concluded that a diverse population of Naashoibito dinosaurs lived at around the same time as the Hell Creek dinosaurs. Earlier scientists surmised that dinosaurs were already on the decline because they studied the colder northern regions, where diversity was lower. However, these results suggest that warmer conditions in the south still supported diverse dinosaur populations. Together, this evidence suggests that dinosaurs were still diverse and thriving 66 million years ago, and that their extinction was indeed a result of the asteroid impact.

Breakthrough Exoskeleton Therapy Promises to Transform Gait Rehabilitation for Stroke Survivors

17 June 2026 at 21:04

Physical therapy for stroke survivors has long relied on the physical presence and hands-on expertise of therapists walking alongside their patients. Now, a remarkable technological leap is reshaping this dynamic. Researchers at Northwestern University in collaboration with Shirley Ryan AbilityLab have unveiled a revolutionary rehabilitation system that forges a direct, real-time link between therapists and patients via robotic exoskeletons. This novel system, known as Therapist-Exoskeleton-Patient Interaction (TEPI), ushers in a new era of highly adaptive, personalized post-stroke gait therapy.

At the heart of TEPI lies a pair of lower-limb exoskeletons worn by the therapist and the stroke survivor, virtually coupled at the hips and knees through a sophisticated control interface. The virtual connection mimics the behavior of springs and shock absorbers, dynamically transmitting forces and movements between the two exoskeletons. This bidirectional, compliant coupling enables therapists to intuitively influence patient gait patterns in real time, offering a level of interaction that is vastly more nuanced than conventional robotic or manual therapies.

Traditional stroke rehabilitation often involves therapists physically assisting patients through limited aspects of movement, constrained by human strength and availability. In contrast, TEPI leverages robotics to augment the therapist’s capacity, delivering whole-body gait training that adjusts fluidly to the patient’s evolving performance. The hands-on adaptability of therapists is thus preserved but enhanced with robotic precision and scalability, facilitating more comprehensive, sustained walking practice without requiring multiple caregivers.

The core engineering breakthrough enabling TEPI is a control framework that models the mechanical interaction between therapist and patient exoskeletons as a coupled spring-damper system. This design imparts compliance and responsiveness, harmonizing the biomechanical inputs from both participants while preventing unnatural or jarring forces. By embedding this interactive virtual linkage, TEPI provides continuous haptic feedback to therapists, allowing them to modulate support, resistance, and corrective assistance in tune with patient movement intentions.

In a recent clinical evaluation published in Science Robotics, TEPI demonstrated superior outcomes compared to conventional therapist-guided treadmill training. Stroke survivors using the system achieved significantly greater joint range of motion, executed longer and higher stepping patterns, and maintained muscle activation at levels comparable to or exceeding standard therapy regimes. Importantly, patient motivation and enjoyment remained consistently high, underlining the system’s potential to foster engagement and adherence during demanding rehabilitation processes.

The TEPI platform addresses prominent limitations of current rehabilitation exoskeletons, many of which rely on rigid, preprogrammed gait cycles that lack real-time adaptability. By contrast, TEPI integrates therapist expertise directly into the robotic control loop, enabling instantaneous behavioral adjustments that match the patient’s unique recovery trajectory. This synergy of human judgment and machine assistance embodies a new paradigm in rehabilitation robotics, where technology serves to amplify, not replace, therapeutic skill.

José L. Pons, the project’s visionary leader and a professor at Northwestern, emphasizes that TEPI’s promise lies in its ability to unify the therapeutic closeness of manual training with the replicability and intensity of robotic interventions. Such hybrid systems are poised to transform stroke recovery protocols by bridging gaps between efficacy, accessibility, and individualized care. They not only alleviate therapist physical burden but also enhance the precision and personalization of rehabilitation exercises.

The development team included multidisciplinary experts spanning mechanical engineering, physical medicine, biomedical engineering, and robotics, fostering innovation at the interface of human-machine interaction and clinical practice. This collaboration ensured that TEPI’s control algorithms and mechanical design were continuously refined based on real-world clinical feedback, resulting in a system deeply attuned to both biomechanical and therapeutic demands.

Looking ahead, the research group plans to expand TEPI’s application beyond treadmill walking, exploring its integration into functionally critical daily activities such as overground ambulation, stair climbing, and sit-to-stand transitions. Longitudinal studies are also underway to assess the benefits of repeated therapy sessions over extended recovery periods. Additionally, efforts are progressing to miniaturize and streamline the technology for potential deployment in home environments, promising scalable remote rehabilitation solutions that can transcend geographic and logistical barriers.

TEPI’s pioneering approach was made possible by funding from the U.S. National Science Foundation’s National Robotics Initiative, reflecting the strategic importance of robotics in advancing healthcare outcomes. By embedding robotic exoskeletons within a responsive therapeutic framework, the system exemplifies how cutting-edge engineering can catalyze transformative changes in the treatment of neurological impairments.

This breakthrough not only advances rehabilitation science but also redefines the human role in therapy. TEPI empowers therapists to become active collaborators with their patients through enhanced, augmented physical connection, promoting a more effective and responsive recovery journey for stroke survivors. It stands as a shining example of innovation that is as empathetic as it is technological — a true step forward in restoring mobility and quality of life.

Uncovering Competitive Reactions in Li–S Batteries

17 June 2026 at 17:59

In the ever-evolving landscape of energy storage technologies, the lithium–sulfur (Li–S) battery stands out for its promise to deliver unmatched energy density and reduced costs compared to traditional lithium-ion batteries. However, progress toward commercial viability has been hampered by complex electrochemical challenges, particularly those involving interfacial charge transfer dynamics. A new study, recently published in Nature, unveils groundbreaking insights into the intricate reaction pathways occurring at solid–liquid interfaces within Li–S batteries, illuminating mechanisms that govern lithium sulfide deposition under realistic, lean electrolyte conditions.

The difficulty in understanding and controlling the conversion of lithium polysulfides (LiPSs) during battery cycling stems largely from the dynamic and highly concentrated nature of reactant distributions at the electrode–electrolyte interface. In these environments, the balance between surface-bound and dissolved species dictates the overall electrochemical performance. The new research deploys advanced in situ liquid-cell electron microscopy techniques to directly visualize these sophisticated concentration gradients, a feat that has eluded scientists due to the liquid phase’s complexity and the scales involved.

What emerges from this study is a revelation of concentration-driven phase segregation phenomena right at the interfacial layers, termed high-concentration interfacial layers (HCILs). These HCILs form as LiPSs aggregate in the immediate vicinity of the electrode surface during cycling, dramatically altering the local reaction environment. This segregation is not merely a passive occurrence; it actively directs charge-transfer dynamics by establishing competitive conditions between surface-mediated and solution-based pathways. The delicate interplay in these zones influences where and how lithium sulfide (Li₂S) nucleates and grows, directly impacting the battery’s capacity retention and cycling stability.

Complementing the microscopy observations, computational explorations using density functional theory (DFT) provide a molecular-level understanding of how LiPS clusters modify their electronic structure upon aggregation. The study identifies that the molecular geometries and orbital hybridizations evolve as LiPSs coalesce, resulting in enhanced electronic interactions that facilitate charge transfer through the concentrated clusters. This phenomenon fundamentally challenges previously held models which treated LiPS species largely as isolated entities, offering a new paradigm that accounts for collective behavior in highly concentrated solutions.

The practical implications of these mechanistic insights are far-reaching. By comprehending how HCILs govern interfacial reaction pathways, the researchers have engineered electrodes that strategically balance surface and solution reactions amidst high LiPS concentrations. These meticulously optimized electrodes enable impressive fast-charging capabilities—reaching rates up to 4 C with current densities of 26.8 mA cm⁻²—without compromising energy density, which itself surges beyond 400 Wh kg⁻¹. Such milestones represent a substantial leap forward in the achievable performance metrics for Li–S battery technology.

This study’s significance extends beyond the immediate Li–S chemistry, addressing a broader challenge in electrochemical energy conversion: capturing and controlling complex interfacial phenomena under dynamically varying concentrations. The in situ liquid-cell electron microscopy method establishes a powerful approach for observing reactive species and phase evolution directly in their native electrochemical environment. As such, it holds promise to transform research across a host of energy storage and catalysis systems where interfacial reactions dictate overall function.

Notably, this work also clarifies why lean electrolyte conditions—essential for practical high-energy devices—have historically been so difficult to optimize. The rich detail uncovered concerning phase segregation and charge transfer competition suggests that managing HCIL formation and stability may be the key to unlocking robust Li₂S deposition and dissolution cycles. Hence, this strategy could mitigate common pitfalls like cathode passivation and capacity fading, which have limited long-term operational viability.

The fusion of experimental visualization with robust theoretical modeling provides a comprehensive framework that future researchers and engineers can exploit to rationally design electrode interfaces. Moving past empirical trial-and-error, the ability to predict and control molecular aggregation behavior and its effects on electronic properties opens new avenues for tuning battery chemistry on an atomic scale. Such sophistication could accelerate the sustainable deployment of lithium–sulfur batteries within electric vehicles, grid storage, and portable electronics.

Moreover, the study emphasizes the profound impact of molecular-level phenomena on macroscopic performance metrics such as charging speed and energy density. By showing that the electrochemical environment at the nanoscale directly modulates reaction kinetics and phase evolution, this research bridges a critical knowledge gap between fundamental science and technological application. It highlights the necessity for integrated approaches combining real-time imaging, theoretical insight, and materials engineering.

Looking ahead, the insights gained are poised to influence material selection, electrolyte formulation, and cell architecture design. Tailoring these elements to favor desirable HCIL characteristics could lead to batteries that not only charge rapidly and store vast amounts of energy but also maintain stability over many cycles. Furthermore, the foundational principles elucidated may inspire innovations beyond lithium–sulfur systems, potentially transforming a range of emerging battery chemistries where interface complexity rules.

In conclusion, this remarkable study marks a pivotal advance in understanding and harnessing the subtleties of interfacial charge transfer within lithium–sulfur batteries. By unraveling the competitive reactions shaped by concentration gradients and molecular aggregation, it charts a pathway toward high-performance batteries ready for real-world demands. As energy storage solutions continue to underpin the clean energy transition, such elegant fusion of fundamental science and engineering innovation will be indispensable for propelling next-generation technologies.

Scientists Create Modular Nanorobot Inspired by Mini Lunar Rockets

17 June 2026 at 17:45

A groundbreaking advancement in nanotechnology has emerged from the University of Basel, Switzerland, where a research team has engineered a sophisticated modular nanorobot exhibiting unparalleled versatility. This innovative system comprises two distinct, reusable components: a propulsion module and a payload capsule, which autonomously self-assemble through a DNA-based molecular Velcro mechanism. Their dynamic interplay offers promising applications across medicine, industry, and environmental science, heralding a transformative direction in nanorobotics research.

Nanorobotics has often been confined to the realm of science fiction, evoking images of minuscule machines navigating within the human body or cleaning up environmental pollutants. However, the rapid progress in this field reflects a new reality where these tiny constructs—differing fundamentally from conventional robots due to their biochemical and nanoscale nature—have started to fulfill tangible roles. Unlike traditional robots equipped with electronic circuits and software, these nanorobots utilize biomolecules and nanoparticles as their building blocks, innovatively combining bioengineering and materials science.

The design philosophy underlying the Basel team’s nanorobot addresses a critical limitation that has hampered previous efforts: specificity of function. Traditional nanorobots tend to be single-purpose entities, finely tuned for a particular task and lacking adaptability. In contrast, this modular system’s architecture allows for the independent development and exchange of functional units, rendering it highly customizable. Such adaptability is pivotal for extending the utility of nanorobots across diverse scenarios, from executing targeted drug delivery within the human body to catalyzing chemical reactions in industrial environments.

At the core of the nanorobot’s structure lies two integral modules. The first is a magnetic propulsion unit, which empowers the nanorobot with directed mobility under external magnetic fields. This enables precise navigation through complex environments—a critical capability for any targeted therapeutic or catalytic application. The second module serves as a payload capsule, designed to securely house and transport therapeutic agents, enzymes, or other functional molecules to desired locations. This segregation of propulsion and payload functions epitomizes engineering elegance at the nanoscale.

The payload capsule is particularly remarkable due to its internal composition. It encapsulates four enzyme-loaded polymer vesicles—nanoscale spherical structures synthesized from polymers that can safeguard and regulate the biochemical cargo within. These vesicles are equipped with nanoscaled pores, facilitating the ingress of substrate molecules and the egress of reaction products while protecting the encapsulated enzymes from premature degradation or deactivation. Moreover, depending on the specific configuration, these vesicles can be selectively triggered to release bioactive substances on demand, a feature critical for controlled therapeutic interventions.

Achieving a robust yet reversible connection between the propulsion module and payload capsule, the researchers employed a DNA-based “Velcro” assembly system. This approach utilizes complementary strands of DNA grafted on the surfaces of both modules, fostering specific and programmable binding through Watson-Crick base pairing. Such molecular precision guarantees that the modules self-assemble and remain stably coupled during operation, yet can be separated and recombined efficiently. This dynamic assembly-disassembly paradigm allows for easy reloading of the payload and recycling of the propulsion units, a major advantage for scalability and cost-efficiency.

Another notable feature enhancing the nanorobot’s functionality is the strategic modification of the payload capsule with biomolecular ligands that enable targeted docking onto specific cells or substrates. Using the human cancer cell line HeLa as a test model, the scientists demonstrated that these nanorobots, when loaded with fluorescent markers, preferentially accumulate on the cell surfaces. This active targeting capability is instrumental for precise delivery of therapeutic agents, ensuring minimal off-target effects and enhancing treatment efficacy.

In a striking demonstration of biomedical potential, the enzyme-laden nanorobots successfully synthesized an anticancer drug directly at the targeted site, reducing the viability of HeLa cells to a mere 16 percent within 72 hours. This localized drug production exemplifies an advanced therapeutic approach where site-specific synthesis and delivery converge, potentially overcoming challenges related to systemic side effects and suboptimal drug concentrations. According to Dr. Voichita Mihali, the lead author, this concentration of drug activity represents a promising strategy for future oncological applications.

Beyond the biomedical sphere, the modular nanorobot’s catalytic prowess, combined with its magnetic propulsion, opens compelling avenues in environmental and industrial contexts. For instance, nanoscale catalysts capable of performing complex chemical transformations can be transported magnetically to reaction sites, where they perform precise functions before being retrieved for reuse. This magnetically enabled recyclability addresses a critical sustainability challenge, aligning with growing demands for environmentally responsible and economically viable technologies.

The ability to dissociate the two modules after task completion and reload the payload capsules before reassembling them underscores the potential for repeated usability. This reusability is vital for practical implementations where cost limitations and material efficiency are paramount. Moreover, it facilitates adaptability, as different payloads can be swapped in according to the specific functional requirement, whether it be therapeutic commands or industrial chemical catalysis.

Importantly, the modular design philosophy extends the nanorobot’s versatility beyond its current framework. By altering the composition of the payload capsule, this platform could be customized for a plethora of applications without necessitating complete redesign. This adaptability accelerates translational research by leveraging a common technological foundation to address multiple challenges spanning healthcare, environmental remediation, and manufacturing.

The interdisciplinary nature of this project also highlights effective scientific collaboration, combining expertise from the National Center of Competence in Research – Molecular Systems Engineering, the Swiss Nanoscience Institute, and Heidelberg University. Such collaborative efforts are critical to tackling the complex engineering and biological challenges inherent in creating functional nanomachines capable of interacting reliably within diverse and dynamic environments.

While the modular nanorobot represents a significant leap forward, its ultimate deployment in human clinical settings remains a long-term objective, contingent on extensive biocompatibility and safety validation. Nonetheless, its current design and demonstrated functionalities establish a crucial foundation. The system’s adaptability and multifunctionality promise to catalyze new directions in nanomedicine and industrial nanotechnology, potentially revolutionizing how minute robots operate and impact their environments.

In conclusion, the University of Basel’s innovative modular nanorobot not only redefines the capabilities of nanoscale machines but also introduces an engineering paradigm centered on modularity, programmability, and reusability. Its ability to combine magnetic propulsion with a versatile, enzyme-loaded payload paves the way for localized therapies and catalysis with unprecedented precision and efficiency. This research marks a transformative milestone that will likely inspire continued exploration into modular nanorobotics, nurturing advancements that could one day address some of the most pressing challenges in medicine and technology.

Scientists Develop Robust Framework to Restore Trust in Global Forest Carbon Credit Systems

17 June 2026 at 15:50

In recent years, forests have emerged as pivotal players in global climate mitigation efforts, representing one of the most promising nature-based climate solutions available today. These ecosystems sequester approximately 31% of anthropogenic carbon dioxide emissions annually, providing a critical buffer against the accelerating pace of climate change. However, the reliability of forest carbon credit systems—mechanisms designed to monetize and incentivize carbon sequestration efforts—has come under intense scrutiny. A groundbreaking study published in the journal Biological Diversity unveils deep-rooted methodological flaws that cast profound doubt on the environmental integrity of current carbon credit frameworks, signaling a crisis of confidence across global carbon markets.

The rigorous analysis, spearheaded by environmental scientists from Yangtze University and Beijing Normal University, meticulously dissects the complex architecture of forest carbon credit systems and identifies four principal structural weaknesses that collectively undermine their trustworthiness. Foremost among these is the use of subjective assessments of additionality, a core concept requiring that credited emissions reductions would not have occurred in the absence of the project. Present carbon credit models predominantly rely on static historical baselines to calculate additionality, yet only an alarming 6% of REDD+ credits—credits allocated under the United Nations’ Reducing Emissions from Deforestation and Forest Degradation program—provide robust empirical evidence to substantiate genuine additional carbon mitigation.

Beyond the critical challenge of additionality, the permanence of carbon sequestration—signifying the long-term retention of carbon stock in forest biomass—is grossly overestimated by current standards. This overestimation is particularly precarious in light of escalating ecological disturbances linked to climate change including wildfires, prolonged droughts, pestilence outbreaks, and inadvertent carbon leakage where forest degradation shifts to unmonitored regions. The failure to appropriately incorporate these growing risks into permanence calculations means that many credited projects likely exaggerate their true contribution to climate mitigation, presenting an illusory picture of impact.

The study further reveals that leakage accounting—the assessment and adjustment for project-driven emissions displacement—is critically underdeveloped. Prevailing methodologies apply a modest average leakage deduction of only 7%, a figure that starkly contrasts with empirical findings suggesting leakage rates ranging from 10% to a staggering 70%. Such systemic under-accounting inflates the perceived net climate benefits of these forest projects, enabling an artificially optimistic valuation of carbon credits within international markets and undermining carbon trading integrity.

Compounding these shortcomings are the conspicuous omissions of biophysical impacts such as albedo and evapotranspiration effects in carbon accounting. Forest ecosystems substantially influence Earth’s energy balance through their reflectance properties and water cycling functions. Neglecting these elements obscures the true net climate impact, as alterations in surface albedo can significantly offset the cooling benefits gained from carbon sequestration, thereby diluting the overall effectiveness of forest-based interventions in climate regulation.

The collective failure to address these intertwined issues has deep ramifications not only for the credibility of carbon markets but also for biodiversity conservation and community well-being, which are often marginalized in project implementation. Insufficient local community involvement and opaque benefit-sharing arrangements risk alienating indigenous stakeholders, raising social equity concerns, and jeopardizing the sustainability and durability of mitigation efforts.

In response to these multifaceted challenges, the research team advocates for a transformative overhaul of forest carbon credit systems through a data-driven, science-based, and integrative accounting framework. Central to this reform is the replacement of static baselines with dynamic monitoring systems that leverage high-frequency remote sensing technologies alongside advanced machine learning algorithms. This approach enables objective, continuous, and quantitative assessments of additionality, dramatically enhancing transparency and scientific rigor in credit issuance.

Addressing permanence requires the establishment of a comprehensive three-tier risk management architecture comprised of prevention, buffering, and insurance mechanisms. This tiered system proactively mitigates disturbances by integrating biodiversity conservation as a mandatory compliance criterion rather than considering it a supplemental benefit, thus embedding ecosystem resilience at the heart of carbon project governance.

Transparency and standardization are equally emphasized through the call for stringent Monitoring, Reporting, and Verification (MRV) protocols. The use of cutting-edge technologies such as Light Detection and Ranging (LiDAR) and environmental DNA (eDNA) is prescribed to ensure precise biomass and biodiversity assessments. Additionally, mandatory disclosure of datasets and verification methodologies aims to foster independent third-party audits, enhancing accountability and stakeholder confidence in carbon accounting practices.

Sociopolitical dimensions are also addressed, with the framework highlighting the critical necessity of formalized community governance structures and the institutionalization of Free, Prior, and Informed Consent (FPIC) procedures. These mandates ensure that forest-dependent communities retain decision-making power and equitable access to the socioeconomic benefits derived from carbon sequestration projects, thereby reinforcing local stewardship and long-term project viability.

While the introduction of these rigorous standards is expected to contract the overall volume of carbon credits issued—reflecting a more conservative and realistic accounting of mitigation gains—the resultant credits will embody higher integrity and trustworthiness. This qualitative transformation is paramount for forest carbon credits to evolve from contested commodities susceptible to skepticism into robust and reliable assets underpinning credible global climate governance.

The implications of this research are profound. By embedding scientific rigor and standardized risk management, forest carbon credits can realize their full potential as durable climate mitigation tools while simultaneously safeguarding biodiversity and respecting community rights. This paradigm shift promises to restore confidence among stakeholders, catalyze more effective climate finance mechanisms, and advance global efforts to stabilize the Earth’s climate system.

Ultimately, this work underscores a crucial message: nature-based climate solutions like forests must be governed by scientifically sound and socially just frameworks. Only through such commitment to transparency, accuracy, and inclusivity can these natural assets deliver genuine and lasting contributions to the fight against climate change.

Got a Google Pixel? Find these 4 Android 17 features ASAP

17 June 2026 at 10:45

Well, hey, how ’bout that? Here we are, on a random quiet-seeming week in June, and a new Android version is officially making its way into the wild and onto our favorite Googley gizmos.

Yes, indeed: Google announced the launch of Android 17 this week, and the rollout is getting underway as we speak. As usual, the software will show up for current, still-supported Pixel devices right away, over the next few to several days. (As for everyone else — well, you know the drill by now, right? It’s up to each individual Android device-maker to process and send out its software updates, and outside of Pixels, that support is exasperatingly unreliable. But odds are, if you aren’t palming a Pixel, you’ll be waiting for a while — maybe even a long while, if you have a phone by a certain manufacturer whose name rhymes with Boatorola.)

As always, some of Android 17’s most important elements are the under-the-hood privacy, security, and performance enhancements that you won’t explicitly see but that will make a critical difference in your device’s ability to operate efficiently and advisably. But this latest Android release also packs an impressive punch of interesting surface-level touches that’ll bring an instant boost to your day-to-day productivity and all-around Android-enjoying experience.

As is often the case, many of the most useful elements are things you might not ever even notice or think to tap into if you don’t know where to look.

Here are the four Android 17 features I’ve found most noteworthy so far and how you can start putting ’em to use this second.

[Psst: Don’t let the learning stop here. Check out my free Pixel Academy e-course to discover all sorts of advanced intelligence lurking within whatever Pixel you’re using!]

Android 17 Pixel feature #1: Bubbles multitasking magic

Our first Android 17 addition on its way to Pixel owners this week is something that’s been in the works for many a moon now — and that’s a handy new multitasking mode known as Bubbles.

Bubbles first came into the Android picture way back in 2019, but at that point, it was limited mostly to messaging and never came close to reaching its full promised potential. At long last, now, Bubbles are back, baby, and becoming everything we’d always wanted them to be.

The simplest way to think about Bubbles is as a way to turn any app you’re using into a floating, collapsible window — so you can pull it up on demand when you want it, then minimize it back down into a small icon (a “bubble” — get it?!) to get it out of your hair but keep it nearby for easy ongoing access.

It’s an interesting way to multitask without having to commit to a full-fledged split-screen setup. It can be quite useful for keeping things like lists, documents, emails, chats, or anything else you’re coming back to regularly at your fingertips — so you can pop into it as needed, without any real effort, but also without having it in your face all the time.

Android 17 Bubbles
Android 17’s Bubbles system in action.

JR Raphael, Foundry

In Android 17, Bubbles is easy to launch with any app in front of you. The only catch is that as of now, at least, it can be triggered only from the standard stock Pixel Launcher — not a custom Android launcher like Smart Launcher or Niagara.

Provided you’re using the standard Android home screen setup, though, all you’ve gotta do is:

  • Press and hold any app’s icon on your home screen or in your app drawer.
  • In the menu that pops up, tap the option that says “Bubble.”
  • Then tap the bubbled app icon to expand or minimize the app, or press and hold it to move it around to any position on your screen or dismiss it.
Android 17 Bubbles (2)
You can move a bubble anywhere on your screen or dismiss it easily.

JR Raphael, Foundry

You can also add additional bubbled apps into that same view via the plus icon next to the first app’s icon when a bubble is open. Pretty nifty, wouldn’t ya say?

Android 17 Pixel feature #2: Smarter location access

Allowing apps access to your location inevitably requires a certain amount of compromise when it comes to the ever-prickly subject of privacy — and it demands a certain level of trust that the apps in question won’t abuse the privilege or use it for reasons beyond their intended purposes.

Android 17 makes it meaningfully easier to accept that bargain and rest easy knowing your info isn’t being misused, thanks to a pair of related new privacy protection measures:

  • First, whenever any app is accessing your location, you’ll now see a blue dot appear in the upper-right corner of your screen — and if you swipe down once from the top of your screen to open your notification panel, you can actually tap on the location icon that appears in its place to get detailed info about exactly which app or apps are involved. With another tap from there, you can opt to force-close the app in question, view all of its recent location access attempts, and manage its location access ability, too, in case anything ever seems amiss.
Android 17 Location Indicator
Android 17 offers some welcome added nuance and power around app location access.

  • And second, when an app asks to access your precise location, Android 17 adds in the option to allow such access only temporarily — for that one brief moment and purpose — without giving the app the permanent permission for ongoing use.

Hey, we’ll take it. Just remember to keep tabs on the permissions Google itself is claiming these days, too, as those don’t always come with a prominent pop-up.

Android 17 Pixel feature #3: More dynamic dark mode

Dark mode may be one of the more divisive interface adjustments of our modern mobile moment, but if you’re a fan of the dimmer, less glary view across your Android experience, you’re bound to appreciate the added option Android 17 affords you in that area.

It’s a simple one-tap checkbox that forces apps to adjust and comply with your dark mode preference, when it’s active — even if they don’t natively support such a setting. That means those pesky apps that’d typically maintain the same standard light interface even when you activate dark mode will now turn dark along with the rest of your setup whenever Android’s dark mode is on.

All it takes it quite literally one tap on the freshly added Android 17 option:

  • Head into the Display section of your Pixel system settings.
  • Tap “Dark theme” — the actual words, not the toggle alongside ’em.
  • And change the setting from “Standard” to “Expanded.”

Now, one note: By forcing apps to adapt to dark mode even if they aren’t designed for it, it’s possible some programs may end up lookin’ a little funky. If that ever happens and you aren’t thrilled with an app’s adaptation, go back to that same settings screen we were just starin’ at and tap the gear-shaped icon alongside the “Expanded dark theme” option. That’ll let you create exceptions and select specific apps that don’t get dark mode automatically applied.

But everything else will now be in the dark when you want it — just like your dark, brooding heart desires.

Android 17 Pixel feature #4: A more comfy all-around view

Whether you’re a prince/princess/dutchess/middle-manager of darkness or not, Android 17’s new Comfort View may be just the thing for you.

Comfort View is an off-by-default addition to your Pixel that applies a softer, more pastel-oriented filter to the display with automatic adjustments based on your current viewing environment — in other words, how bright it is around you at any given moment. Ooh, ahh, etc.

To try it out, march your way back into those Display settings, and this time, tap the line labeled “Comfort Filters.” Flip the switch next to “Comfort View,” make sure the “Dynamic” checkbox is active, and see how you feel about your newly optimized screen-color view as you move throughout your day.

If you find the filtering to be too extreme or not enough to make a difference, you can also try disabling the “Dynamic” option there and then manually adjusting the “Intensity” slider to suit your specific peeper preferences. But I suspect if you give it enough time, you’ll find the automatic adjustments to be one of those things that just works for you and makes your device a little easier on the eyes, relative to each and every viewing environment — without being something you actively think about or pay much mind.

That, if you ask me, is the sign of an effective feature. And it’s a welcome addition to Android and the ever-evolving Pixel experience.

Revolutionary High-NA Lithography Optical System Set to Transform Semiconductor Chip Manufacturing

17 June 2026 at 08:14

In the rapidly advancing world of semiconductor technology, the relentless pursuit of smaller, faster, and more energy-efficient computer chips is critical to powering the next wave of innovation—from artificial intelligence mega-data centers to cutting-edge medical devices and ubiquitous consumer electronics. At the frontier of this evolution lies extreme ultraviolet (EUV) lithography, a sophisticated method capable of etching circuit patterns at the nanometer scale. However, the intrinsic complexities and astronomical costs associated with current EUV lithographic systems have presented formidable barriers to wider adoption and scalability. Now, a groundbreaking proposal from Professor Tsumoru Shintake of the Okinawa Institute of Science and Technology (OIST) offers a transformative vision for this technology, promising to revolutionize semiconductor manufacturing with unprecedented precision, reduced complexity, and drastically lower costs.

EUV lithography operates by harnessing light with an extraordinarily short wavelength—just 13.5 nanometers—which enables the creation of incredibly fine features on silicon wafers. The process begins when this EUV light is generated and meticulously channeled through an illumination system towards a reflective photomask imprinted with the target circuit design. Upon reflection, this patterned light passes through a projector system composed of precisely curved mirrors, which shrink and focus the intricate design onto a silicon wafer. Subsequent processing etches the illuminated pattern into the wafer’s surface, forming the foundational architecture of semiconductor chips. Crucial to pushing the envelope of miniaturization is the numerical aperture (NA) of these systems—a parameter that defines the range of angles over which the system can accept or emit light. Higher NA values correlate directly to finer resolution capabilities, enabling denser packing of transistors and circuit elements.

Despite the theoretical promise of high-NA EUV lithography, practical implementation has been fraught with challenges. The early explorations into high-NA configurations favored simple in-line setups wherein the photomask, projector, and wafer are aligned along a single optical axis. This streamlined arrangement, while intuitively appealing, introduced significant optical aberrations such as distortions and blurring that intensified with increasing NA. These so-called “mask 3D effects” arise due to the complex interplay of light reflections on the three-dimensional topography of the photomask, adversely affecting pattern fidelity and ultimately the electrical performance of the fabricated chips.

Confronting these longstanding obstacles, Professor Shintake embarked on an ambitious reimagining of the illumination and projection components integral to high-NA EUV lithography. His initial foray involved evaluating the feasibility of a minimalist projector design consisting of a single pair of mirrors—one concave and one convex—with the potential to deliver high-resolution imagery while suppressing aberrations. Although this simplistic approach did not yield immediate success, continued exploration led to a sophisticated two-stage projection configuration. Each stage utilizes a concave-convex mirror pair arranged to optimize optical performance. Remarkably, simulations revealed that carefully orchestrated multiple reflections between these mirrors could cancel out deleterious optical defects, preserving the high numerical aperture without compromising image quality.

These insights emerged from extensive computational modeling conducted using OpTaliX, an advanced optical simulation software. Through meticulous parameter optimization, including mirror curvature adjustments and precise spatial positioning, Shintake and his collaborators delineated an optical path that maintains high resolution while mitigating the distortive mask 3D effects. The theoretical framework underscores the power of optical engineering in overcoming fundamental diffraction and interference phenomena—challenges that have hampered high-NA EUV lithography efforts for decades.

Beyond the technical elegance of the design, the proposed system carries profound economic implications. Current state-of-the-art EUV lithography machines reportedly cost hundreds of millions of euros each, placing them out of reach for all but the largest semiconductor manufacturers. In stark contrast, Shintake’s approach promises to slash these costs dramatically—potentially to just a quarter of today’s expenditures—thus democratizing access to cutting-edge lithography and accelerating development cycles across the industry.

The ramifications extend well beyond chip manufacturing economics. The International Energy Agency forecasts that by 2030, global data center electricity consumption will double, driven largely by the proliferation of energy-intensive artificial intelligence applications. Higher-density chips fabricated with the new high-NA technology would feature electronic pathways shortened by virtue of their finer architectural detail, reducing signal travel distance and thereby minimizing energy loss during computation. Moreover, lower heat emission from these denser chips implies diminished cooling requirements, collectively resulting in meaningful reductions in power consumption and operational costs for data centers worldwide.

As part of his next research phase, Professor Shintake and his team aim to transition from simulation to realization by constructing a physical prototype of the novel high-NA EUV lithography system. This endeavor will necessitate overcoming engineering challenges such as fabricating mirrors with near-perfect reflectivity and minimal surface defects—criteria assumed in simulations but challenging to achieve in practice. Nonetheless, the initial groundwork laid by this study establishes a compelling blueprint for transforming semiconductor fabrication.

In addition to enabling finer patterning capabilities, the simplified in-line projector design enhances overall system robustness and manufacturability. By aligning the photomask, projector, and wafer along a single axis with optimized mirror pairs, the architecture reduces alignment complexities and optical component counts, thereby facilitating easier maintenance and potentially accelerating throughput rates on the manufacturing floor.

Innovations like Shintake’s not only refresh the physics of lithographic imaging but may also catalyze novel computing paradigms by significantly pushing the achievable limits of miniaturization. As industry demand for memory density and logic efficiency mounts exponentially, high-NA EUV lithography could unlock pathways to next-generation chip designs exhibiting superior speed, reduced energy consumption, and lower production costs, collectively powering advancements in artificial intelligence, quantum computing, and ubiquitous digital technologies.

Ultimately, this research signals a pivotal juncture for semiconductor manufacturing, harnessing the power of optical science to surmount entrenched technical and financial hurdles. By reducing the cost and complexity of high-NA EUV lithography, Professor Shintake’s innovation promises transformative impacts on the silicon industry and beyond—enabling faster, greener, and more affordable electronics that will underpin the data-centric future of society.
