Apple TV’s Emmy-nominated stars packed Spago for The Hollywood Reporter’s “Women of Apple TV” panel, where Michelle Pfeiffer confessed she never wants to lead a movie again, Elle Fanning celebrated the freedom to play messy and judged characters in Margo’s Got Money Troubles, and Rhea Seehorn pushed back hard on claims her Pluribus survivor is “unlikeable.” Jessica Williams, Dale Dickey, and Karolina Wydra joined the candid chat about complicated women, creative allies, and the pure joy of seeing roles this rich on screen.
Kirsten Chuba for The Hollywood Reporter:
“THR x Apple TV’s Leading the Narrative: The Women of Apple TV” event took over Spago Beverly Hills for a conversation among Margo’s Got Money Troubles stars Michelle Pfeiffer and Elle Fanning, Pluribus‘ Rhea Seehorn and Karolina Wydra, Shrinking actress Jessica Williams and Widow’s Bay scene-stealer Dale Dickey, moderated by Shrinking writer-producer Ashley Nicole Black.
Black kicked off the panel — in front of a room full of influencers and tastemakers — by emphasizing, “I can’t believe all of these performances happened in the same season; I remember being a young woman where you would get one really cool female character per season. To get all of these iconic performances in one is just like, my mind is blown.”
Later in the conversation, Seehorn reacted to the feedback from some viewers that her character in Pluribus, one of only 13 people in the world immune to a virus that transformed the rest of humanity into a peaceful hive mind, is “unlikeable.”
“I disagree; personally I would have taken eight more episodes to get up off the floor so I think she’s kind of doing well, really,” teased Seehorn, who is up for lead actress in a drama series.

In an unprecedented exploration of Earth’s dynamic geological processes, researchers have delved deep into the sedimentary history of China, unraveling the intertwined influences of natural climate fluctuations and human activities on sediment transfer since the Last Glacial Maximum. This expansive study, published in Communications Earth & Environment, ushers in a new era of understanding about how sediment movement across this vast and ecologically diverse landmass has evolved over tens of thousands of years, with profound implications for environmental science, climate change, and land management strategies worldwide.
Sediment transfer—the movement of soil, rock, and organic material across landscapes by rivers, wind, and human activity—is a critical process governing terrestrial and aquatic ecosystems. It affects soil fertility, landscape morphology, water quality, and carbon cycling, thereby linking the geosphere, biosphere, and atmosphere. Until now, however, the relative roles of climate versus anthropogenic disturbances in shaping sediment dynamics over millennial timescales remained unclear, particularly in regions like China, where dramatic climatic shifts and massive population expansions have coexisted.
The research team, led by Li M., Huang H., and Izumi K., embarked on a multidisciplinary journey combining sediment core analyses, isotope geochemistry, paleoclimatic reconstructions, and historical land-use records. Their approach integrated high-resolution dating techniques and advanced computational modeling to discriminate between sediment deposition patterns driven by natural glacial-interglacial cycles and those triggered by human interventions such as agriculture, deforestation, and urbanization.
One of the cornerstone revelations from this study centers on the prominent sediment flux variations linked to the Last Glacial Maximum approximately 21,000 years ago. During this period, extensive glaciation and colder, drier conditions significantly altered river regimes and erosion dynamics. The researchers documented pronounced reductions in sediment supply due to diminished vegetation cover and altered precipitation patterns, highlighting the impact of climatic extremes on Earth surface processes.
Moving forward into the Holocene epoch, the warming climate catalyzed vegetation recovery and increased precipitation, resulting in intensified sediment mobilization. Yet, what sets China apart is the overlay of accelerating human activity from the Neolithic period onward. The study meticulously characterizes how early agricultural expansion began reshaping erosion rates and sediment exports, effectively modulating the natural sedimentary balance established by climate alone.
The team’s integration of paleoenvironmental datasets with archaeological evidence allowed them to trace how intensive land use, particularly during the last 5,000 years, drove landscape erosion that amplified sediment transfer into river basins and eventually into marine sediments. This co-evolution of human societies and sediment dynamics speaks volumes about the Anthropocene’s footprint extending much deeper into antiquity than previously assumed.
Perhaps most strikingly, the researchers observed that over the past two millennia, rapid urban growth, industrial development, and large-scale engineering projects such as dam construction have profoundly altered sediment pathways. The modification of river networks and sediment trapping in reservoirs markedly reduced sediment load downstream, disrupting natural sediment replenishment processes essential for delta stability and ecosystem health.
Equally significant was the finding that climate variability continued to exert influence, occasionally exacerbating or mitigating human-driven sediment trends. For instance, severe droughts and flooding events integrally tied to climate oscillations periodically accelerated soil erosion or sediment deposition, showcasing a complex feedback loop between climate systems and anthropogenic pressures.
From a methodological standpoint, the study demonstrates the power of coupling sedimentological evidence with emerging geospatial technologies and modeling frameworks. The team’s innovative analytical pipeline enabled unprecedented spatial and temporal resolution, paving the way for predictive assessments of sediment flux responses under future climate and development scenarios.
This comprehensive chronicle of sediment transfer across China also underscores broader global concerns. Given China’s pivotal role in regional and global biogeochemical cycles, understanding its sediment dynamics is vital for anticipating downstream impacts—ranging from river delta subsidence and coastal erosion to nutrient loading that affects marine ecosystems far beyond national borders.
Importantly, this work highlights sediment transport as an essential climate indicator and environmental parameter, providing valuable insights into past Earth system behavior. Such knowledge empowers policymakers to devise sustainable land and water management policies that balance developmental goals with ecosystem preservation.
The implications for global sediment budgets are profound, as similar interactions between climate variation and human land use are occurring worldwide. As countries grapple with increasing pressures on landscapes due to population growth and climate change, the lessons from China’s sedimentary history resonate widely, emphasizing the necessity of integrated environmental monitoring and adaptive land management.
By revealing the subtle dance between climate forces and human footprints over millennia, this research reshapes our perception of Earth surface processes as deeply interconnected socio-natural phenomena. It urges the scientific community to look beyond simplistic cause-effect paradigms and embrace complexity when addressing environmental challenges.
In essence, the study represents a paradigm shift in sedimentology and environmental science, illustrating how ancient and modern drivers converge to craft the landscapes we inhabit today. The elegant synthesis of data and theory presented by Li, Huang, Izumi, and colleagues sets a gold standard for future inquiries into Earth’s dynamic sedimentary record.
As the climate crisis advances and human transformations accelerate, understanding these profound historical sediment transfer mechanisms from China offers a crucial blueprint for safeguarding ecological and societal resilience across the Anthropocene epoch.

Deep within our planet lies a critical interface known as the core–mantle boundary (CMB), a region where extreme temperatures and dynamic processes converge to shape Earth’s thermal and magnetic evolution. Recent research has illuminated the intricate behaviors of heat flow at this boundary, revealing how variations here influence the geodynamo—the mechanism responsible for Earth’s magnetic field. A groundbreaking study now explores how distinctive structures in the lowermost mantle can actually reverse the expected direction of heat transfer, fundamentally altering our understanding of how the deep Earth operates.
The core’s heat output and the mantle’s behavior are intimately linked, but spatial and temporal variations in heat flux at the CMB complicate this relationship. Heat flow from the core into the mantle typically fuels convective currents in the liquid outer core, driving the geodynamo process that sustains Earth’s magnetic shield. However, recent sophisticated simulations suggest that beneath certain geological features in the mantle, heat might instead flow back toward the core, a phenomenon previously unconfirmed and challenging conventional geophysical assumptions.
Central to this discovery are large low-shear-wave-velocity provinces (LLSVPs), massive structures located at the base of the mantle. These provinces are identifiable by their diminished seismic wave speeds, which geophysicists interpret as reservoirs of anomalously hot, chemically distinct materials. The new study models these LLSVPs with enhanced thermal conductivity adjustments and accounts for excess internal heating, simulating how these features interact dynamically with heat flow near the CMB.
The simulations reveal a striking phenomenon: heat flux directly beneath LLSVPs can be locally negative. This means, counterintuitively, that heat is being transferred from the mantle back into the core. This unexpected reversal challenges prior models which generally assumed a consistent outward flow of heat from core to mantle. Such negative fluxes have profound implications not only for the thermal balance of the Earth’s interior but also for the longevity and variability of its magnetic field.
Moreover, the research underscores that throughout the base of the mantle piles associated with LLSVPs, the heat flux remains lower than the adiabatic heat flux of the core. This thermal configuration suggests a degree of regional stratification at the top of the core, potentially explaining discrepancies observed in seismic and geomagnetic data. In other words, the topmost layer of the core may be thermally segregated in ways that we had not confirmed previously.
Interestingly, the study also explores the impact of subducted slabs—denser fragments of oceanic lithosphere—that eventually reach the CMB. The arrival of these slabs triggers pronounced spikes in heat flux, dramatically increasing the heterogeneity of lateral heat flow along the core–mantle boundary. This dynamic enhances the complexity of heat exchange patterns and further influences the geodynamo’s behavior, potentially affecting geomagnetic activity on geological timescales.
A significant implication of these findings relates to so-called “superchrons,” intervals lasting tens of millions of years during which Earth’s magnetic field remains stable without reversals. The occurrence of locally negative heat flux beneath the LLSVPs might explain these long periods of geomagnetic quiescence. When heat flows reversely into the core, it can alter convection patterns in ways that suppress the typical polarity flip mechanism, shedding new light on the origin and cessation of superchrons.
The study’s approach involved advanced mantle thermochemical convection modeling that incorporates temperature-dependent thermal conductivity and internal radiogenic heating within dense mantle piles. This methodological innovation provides a more realistic representation of the mantle’s behavior at extreme conditions than previous models, enabling researchers to capture subtle but critical feedbacks influencing heat fluxes at depth.
By reconciling seismic data, which reveals complex structures in the lowermost mantle, with geomagnetic observations that hint at temporal variability in the geodynamo, this research bridges a vital gap in Earth sciences. The correspondence between the spatial extents of LLSVPs and anomalies in the geomagnetic field suggests a coupling mechanism mediated through heat flux variations being directly tied to mantle dynamics.
The nuanced understanding of heat flow gleaned from this work also carries implications for the planet’s thermal evolution over geologic time. How heat migrates across the CMB influences the cooling rate of the core, the crystallization of the solid inner core, and consequently the lifecycle of the geodynamo. The discovery that heat transfer is not unidirectional, but can locally reverse in space and time, necessitates revisiting models of Earth’s deep thermal history and magnetic field generation.
This revelation also lays groundwork for interpreting seismic tomography results with a new lens, appreciating that chemical and thermal heterogeneity in LLSVPs exerts a tangible impact on core processes. The presence of chemically distinct reservoirs affects not only the mantle’s physical properties but also its thermal gradient with direct knock-on effects for core convection patterns and magnetic field intensity.
Such interconnectedness across Earth’s deep interior underscores the planetary-scale complexity of thermal and compositional interactions driving Earth’s long-term stability. The core-mantle boundary emerges not simply as a static physical barrier but as a dynamic interface where thermal regimes, chemical signatures, and fluid motion all coalesce to modulate our planet’s magnetic heartbeat.
Future research building on these findings may sharpen our forecasts for geomagnetic field behavior, including its reversals and excursions, by incorporating the interplay of mantle structures and heat flux heterogeneity shown in this study. Understanding these processes is not merely academic; Earth’s magnetic field shields life on the surface from charged solar particles, making geomagnetic stability crucial for habitability.
In conclusion, the discovery of negative heat flux beneath LLSVPs represents a paradigm shift in understanding Earth’s deep thermal dynamics. It opens fresh avenues into interpreting Earth’s magnetic field history and its deep interior’s energy budget, challenging geoscientists to refine their models of the planet’s evolving mantle and core mechanisms. The study invites a reconsideration of how internal heat governs the interplay between mantle convection and geomagnetic phenomena, securing a pivotal advance in the geophysical sciences.
As our planet continues its ceaseless churn beneath the crust, these findings remind us that Earth’s interior is a realm of profound complexity and subtle interactions. The dance of heat and composition at the core-mantle boundary not only choreographs magnetic field generation but ultimately shapes the environment that sustains life above ground. Unlocking its secrets brings us closer to comprehending the planet’s past, present, and future in extraordinary detail.

Last week, we looked at a new study of the origin of complex cells, one that showed that our ancestors' genomes were pieced together from bits and pieces of multiple species. It put a spotlight on a phenomenon called horizontal gene transfer, in which a gene from one species is incorporated into the genome of a distantly related species. The frequency of horizontal gene transfer means that, in addition to the neatly branching trees that relate species by common descent, there are small threads connecting distant branches of the tree of life.
It's easy to see why horizontal gene transfer would be common among microbes. They often live in complex communities that are likely awash in the DNA of dead and damaged cells. Plus, bacteria and archaea lack a membrane between their DNA and the rest of the cell, making it easier for environmental DNA to find its way to the genome.
However, a new study this week shows that horizontal gene transfers are remarkably common even in multicellular animals. And it does so by examining the genomes of multiple cockroach species, which have had bits of bacterial DNA for millions of years.

In a groundbreaking advance for microbiome science and viral ecology, researchers at Rice University have unveiled a revolutionary RNA barcoding system that reveals intricate interactions between bacteriophages—viruses that infect bacteria—and their bacterial hosts within complex microbial communities. This novel technique, recently described in the prestigious journal Nature Communications, offers an unprecedented lens through which scientists can decode the vast and hidden landscape of phage-host dynamics, potentially transforming microbiome engineering and therapeutic interventions.
Bacteriophages, the most abundant biological entities on our planet, orchestrate microbial ecosystems by infecting bacteria, altering their metabolic functions, and facilitating horizontal gene transfer—a natural mechanism for distributing genetic material across bacterial populations. Despite their ubiquity and ecological importance, unraveling which specific phages interact with which bacterial hosts in natural and engineered environments has remained an elusive challenge, primarily due to limitations in traditional culture-based methods and the complexity of microbial consortia.
The team, led by Lauren Stadler, Associate Professor of Civil and Environmental Engineering at Rice University, has pioneered a synthetic biology platform leveraging RNA-addressable modification, originally designed to monitor gene transfer via bacterial conjugation. Central to this approach is an engineered ribozyme that inserts unique molecular barcodes directly into the 16S ribosomal RNA of bacterial recipients following successful DNA transfer from a phage. This molecular tagging allows precise identification of host organisms through RNA sequencing, bypassing the need for labor-intensive bacterial culturing and enabling high-throughput analysis directly within environmental samples.
Applied to the well-characterized bacteriophage P1—known for its DNA transfer capabilities among enteric bacteria—the system revealed not only anticipated host range patterns but also uncovered a surprising new group of hosts in environmental wastewater samples: members of the order Aeromonadales, including Aeromonas hydrophila. This finding is particularly striking given that Aeromonas hydrophila had not previously been identified as a P1 host, underscoring the technology’s capability to unmask previously hidden phage-bacterial relationships within complex ecosystems.
The ability to detect these cross-order interactions is more than a mere academic curiosity; it offers critical insights into gene flow mechanisms that may fuel the spread of antibiotic resistance and influence microbial community stability. Traditional methodologies often confuse surface attachment of phages with genuine infection and DNA transfer. However, the RNA barcoding approach distinctly traces successful transduction events, allowing researchers to discriminate true host interactions from transient viral contacts.
Moreover, the Rice research team demonstrated that subtle genetic variations in phage tail fibers—protein structures critical for host recognition and binding—can drastically redefine a phage’s host range. By engineering phage particles with different tail fiber compositions and deploying their barcoding system within wastewater microbial consortia, they mapped how each fiber variant targeted a unique subset of bacteria. These insights provide an invaluable blueprint for designer phages with tailored host specificity, potentially catalyzing advancements in phage therapy and targeted microbiome modulation.
The implications of this technology extend far beyond wastewater treatment plants. As microbiome research continues to gain momentum in medicine, agriculture, and environmental science, the ability to efficiently monitor and understand viral gene exchange pathways promises to accelerate the development of phage-based alternatives to antibiotics, precision microbiota editing, and enhanced bioremediation strategies. Because the system is compatible with standard amplicon sequencing techniques, it lends itself to scalable deployment for large environmental surveys and clinical studies alike.
This innovative research was carried out through an interdisciplinary collaboration spanning Rice University’s civil and environmental engineering, biosciences, bioengineering, and chemical and biomolecular engineering departments, as well as the Systems, Synthetic and Physical Biology Graduate Program. The team included notable contributors such as James Chappell, associate professor of biosciences, and Jonathan Silberg, Stewart Memorial Professor of BioSciences, alongside doctoral graduate Zachary LaTurner—now a postdoctoral researcher at UC Berkeley’s Innovative Genomics Institute—and Rice graduate students Matthew Dysart, Samuel Schwartz, and Elizabeth Zeng.
In a broader context, this study spotlights the transformative potential of synthetic biology tools to decode biological complexity, enabling researchers to untangle the dense web of microbial interactions that govern health and disease in humans, animals, and natural environments. By providing a scalable, sensitive, and accurate method to chart phage-host relationships, the RNA barcoding system represents a major leap forward—a new frontier in the quest to harness viruses as precision instruments in biotechnology and medicine.
As bacteriophages gain recognition as powerful alternatives to traditional antimicrobial therapies amidst rising antibiotic resistance, tools like this RNA-based system will be crucial for understanding and safely deploying phage interventions. The meticulously engineered approach that allows direct observation of viral gene transfer events opens avenues for designing phages that deliver beneficial genes or selectively eliminate harmful microbial species with surgical precision, revolutionizing future therapeutic and environmental applications.
Rice University’s pioneering work injects fresh momentum into the fast-evolving field of microbiome science, providing a versatile, high-throughput technique to explore viral influences on bacterial populations in situ. This innovation promises to inspire a wave of research initiatives aimed at mapping the viral “dark matter” within microbiomes—complex microbial ecosystems influencing global biogeochemical cycles, human health, and industrial processes.
As scientists embrace this RNA barcoding platform, the microbial world’s hidden dialogues—encoded in viral gene transfers—may soon be decoded with clarity and scale that were previously unimaginable. Unlocking these intricate viral-bacterial conversations not only enriches our fundamental understanding of microbial ecology but also propels the design of next-generation biotechnologies, setting the stage for a paradigm shift in how we interact with the microbiome and its viral inhabitants.

As NASA plans long-term missions on the Moon, the agency could use robots to perform routine tasks, allowing crew members to dedicate more time to science and exploration. However, robotic motion control requires complex technology and advances in features like robotic decision-making and object recognition.
These are the challenges a Boulder, Colorado-based robotics company is teaming up with NASA to overcome.
PickNik Inc. recently worked with Shaun Azimi, who leads the Dexterous Robotics team at NASA’s Johnson Space Center in Houston, and other agency roboticists. The team tested software that enabled a robotic arm to recognize a spacecraft hatch, then turn the latch, grasp the handle, and open the door. The arm then was able to transfer cargo bags between the hatch and a bin.
The work was carried out in NASA Johnson’s new Integrated Mobile Evaluation Testbed for Robotics Operations with funding from NASA’s Small Business Innovation Research program.
PickNik designed and refined the robotic software, called MoveIt Pro, with support from early government investments. Commercially released in 2023, MoveIt Pro has found a significant customer base.
Automotive company BMW is using the software on its robotic assembly lines. A company called Lightspeed is using MoveIt Pro to program huge robotic arms that build modular “panels” for constructing affordable housing. Another company, known as Hivebotics, used MoveIt Pro to automate its flagship product, a cleaning robot.
Ezra Brooks, principal software engineer at PickNik, said the 35-person company might not have a product without NASA’s early support. Robotic software requires years of research and development to refine algorithms and create a commercial product. NASA enabled much of that foundational work.
NASA’s technological advancements unlock key capabilities for missions at the Moon and beyond while benefiting commercial industries on Earth. For 50 years, NASA has documented the everyday benefits of space technology through the agency’s Spinoff publication. To learn more about the project, visit: https://go.nasa.gov/49CNSi7
