Um dos jogos mais cultuados de todos os tempos, The Legend of Zelda: Ocarina of Time — lançado originalmente em 1998 para o console Nintendo 64 —, agora pode ser jogado nativamente em iPhones e iPads.

Essa opção se tornou uma realidade graças ao projeto de código aberto HarkinianPad, do desenvolvedor Karis [@chrissotraidis]. Criado com a ajuda do Codex 5.6 Sol, ele é baseado em outro projeto que ganhou certa notoriedade há alguns anos: Ship of Harkinian — versão decompilada de Ocarina of Time capaz de rodar em dispositivos com macOS, Windows, Linux e Android — bem como os consoles Nintendo Switch e Nintendo Wii U.

Segundo Karis, o jogo foi decompilado para a linguagem de programação C e, então, reconstruído como uma aplicação ARM64 (a arquitetura dos processadores da Apple) nativa. Ele também garante que nenhum elemento do hardware do Nintendo 64 é simulado pelo seu projeto, que renderiza o game via Metal — framework proprietário da Maçã.

Por se tratar de uma versão nativa, é possível colocar Ocarina of Time para rodar em widescreen, na resolução completa do iPhone/iPad e a 60 quadros por segundo. Para efeito de comparação, o console da Nintendo roda o game a 240p e com uma taxa de quadros de aproximadamente 20qps.

Configurar tudo no seu smartphone ou tablet, no entanto, não é exatamente simples, já que, para rodar, o HarkinianPad precisa, primeiro, ser assinado por uma Conta Apple ou por um time de desenvolvimento. A página do projeto no GitHub, no entanto, oferece um passo a passo (em inglês) bem completo com várias opções de instalação.

Você também vai precisar extrair a ROM ¹Read-only memory, ou memória somente de leitura. de uma edição física do jogo para rodá-lo no seu dispositivo, já que o projeto não vem com uma cópia por questões legais.

Uma vez que tudo for configurado, no entanto, é possível aproveitar Ocarina of Time em sua completude, embora seja possível que você esbarre em alguns problemas de áudio dependendo do dispositivo escolhido. O HarkinianPad também conta com suporte a controles de videogame, teclados e mouses — além dos controles adaptados para a tela sensível ao toque.

Boa jogatina! 🎮

This instruction is a fever dream of three weird things in sequence:

• What on earth is “QuickTime”?
• I am recording with a player?
• Why can’t I choose the option [“New Screen Recording”] that describes exactly what I want to do?

[…]

It’s noticing this kind of complexity, places where an easy way was chosen, design debt accumulated, and things got simply too weird. Apple allowed three weird things to accumulate here.

It makes sense in terms of the history and how the technology works, but from a clean slate one might expect this functionality to be in the Screenshot app, Screen Sharing, iPhone Mirroring, or perhaps even Finder.

Apple:

With software updates this fall, parents will be able to access new child safety features, including a simpler setup experience with a recommended set of essential apps, Ask to Browse, Time Allowances, and a redesigned Screen Time. These updates enhance Apple’s already industry-leading parental controls and underscore its commitment to building a safe and trusted platform for kids.

[…]

For years, Apple has integrated guidance from leading clinical and child development research, as well as online safety experts, into its products and services, and continues to help advance research into children’s digital wellbeing. Apple is working with the American Academy of Pediatrics (AAP) to adapt its Family Media Plan into a guide parents can reference when using Apple products. Apple also continues to collaborate with researchers to understand the impact of technology on children’s wellbeing, and is committed to advancing the science in this area.

Unanswered is whether they fixed Screen Time so that it actually works now. Currently, it’s a complete mess of settings that get lost, reports that don’t sync, and protections that manage to break sites and apps yet are also easily bypassed. Separately, it’s confusing and difficult to configure, but it seems like that part is improving. It’s hard to believe there wasn’t already a way to ask permission to access a new Web site.

Adam Engst:

To help parents manage how long children spend on allowed apps, Apple has introduced time allowances. A daily time allowance spans entertainment, games, and social media, with each category having its own allowance. Time allowances can vary by time of day and day of week as well, to keep kids from using certain apps during school and to allow more flexibility on weekends.

Does it support weekly rather than daily allowances?

Jennifer Pattison Tuohy:

Apple spending a big chunk of its WWDC keynote on parental controls was surprising for several reasons. But the biggest is that, despite all the airtime, it didn’t announce much new beyond a redesigned interface. Almost all the features touted already exist or are upgrades to current options. Why Apple chose to do this isn’t a mystery. You can trace the threads from the recent landmark social media trials against Meta and Google to the protesters outside the Cupertino HQ today: Apple is trying to show the world it’s being responsible when it comes to your children.

Craig Grannell:

Curious to see Mastodon almost unanimously hostile to the keynote parental controls bit. Maybe I’m missing something, but the vast majority of what was shown was iteration on existing features.

Corentin Cras-Méneur:

AND screen time and parental controls should actually work?? It feels like an early Christmas :->

• The Age Verification Trap

Update (2026-06-11): Craig Grannell:

But here’s the thing: the Screen Time system already existed. What Apple announced isn’t so much new features as the refinement of existing ones.

[…]

There will always be edge cases. Apple must get better at understanding them. But giving parents more flexibility strikes me as preferable to the current Screen Time system and blanket government-level bans – or demanding adults constantly prove their age online to do anything.

It remains to be seen whether Apple’s changes will actually hold off any government-level bans.

freediverx (Mastodon):

Apple continues to design child safety features based on guidance from “leading clinical and child development research” and “online safety experts” while neglecting to consult independent security, privacy, and civil rights experts and advocates.

Update (2026-06-16): The Talk Show with Joanna Stern and Nilay Patel had a great segment on parental controls and Screen Time.

One of Apple’s tentpole features at WWDC was a ground-up makeover to Screen Time that’s designed to give parents more granular and reliable control over their kids’ device use. I got a demo of the changes while I was at Apple Park, and they’re extensive. That’s good because Screen Time has been broken in a variety of ways for a while and isn’t very flexible.

My first impressions of the changes have been positive, but it’s worth noting that I don’t use Screen Time myself and my kids are grown. Screen Time wasn’t even available when it would have been useful to my family.

However, I do remember well the days when my kids were little, and so I sympathize with Patrick Klepek who wants more. Klepek gives Apple credit for improvements in Screen Time’s UI, but wants more:

But to crystalize my requests to Apple for the future:
- A dedicated Screen Time app
- The ability to invoke Siri or other shortcut-like features to lock devices
- Granular control over extending screen time to accommodate specific requests

I’d add another request that one of the journalists made during our demo that made a lot of sense. Like me, he has three kids and wondered if he could set up a baseline set of Screen Time rules and then copy them to his other kids, making age-appropriate tweaks for each kid. Apple said that isn’t currently possible, but it’s the sort of practical, reality-based suggestion that the company should prioritize. Being a parent means a lot of things, but it shouldn’t mean being an IT manager too. For tools like Screen Time to be adopted, they need to be easy, flexible, and powerful. That’s a tough combination, but I hope it’s been made a priority internally at Apple that will result in ongoing improvements to Screen Time during this OS cycle and beyond.

A new Bayesian system called ALADYNOULLI is designed to forecast how multiple diseases unfold over time from longitudinal electronic health record (EHR) histories. The work targets a central challenge in longitudinal modelling: evaluating prediction without “information leakage,” so that future diagnoses never influence training for past timepoints. By explicitly simulating real clinical follow-up, the researchers aim to make risk estimates more trustworthy for decision-making.

In the primary assessment, ALADYNOULLI produced dynamic 1-year forecasts at 10 fixed moments during follow-up, starting at enrollment and extending to years 1 through 9. At each timepoint, models were retrained using only data available up to that moment, then tested on 1-year outcomes. The key metric was the median area under the receiver operating characteristic curve (AUC) across these dynamic evaluations, summarizing how predictive accuracy changes as new diagnoses accumulate.

The study spans 28 diseases and reports robust discrimination for several clinically important endpoints. Performance was strong for atherosclerotic cardiovascular disease (ASCVD), breast cancer, atrial fibrillation, heart failure, and Parkinson’s disease, with AUC values of 0.879, 0.867, 0.801, 0.811, and 0.796, respectively. Importantly, the evaluation excluded people with prevalent disease at prediction time, aligning the comparisons with prospective risk.

ALADYNOULLI was also benchmarked against established clinical risk tools where feasible. At enrollment, static models trained only on baseline information were compared for both 1-year and 10-year horizons. While longer-term predictions naturally degraded, ALADYNOULLI retained meaningful power—for example, for ASCVD at 10 years—highlighting the advantage of learning from longitudinal EHR trajectories rather than relying solely on cross-sectional inputs.

Calibration analyses further supported reliability: predicted and observed event rates matched closely across millions of at-risk patient-time observations. The researchers report a mean squared error on calibration of 4.67 × 10⁻⁷, with mean predicted rates (5.55 × 10⁻⁴) closely tracking mean observed rates (5.45 × 10⁻⁴). This suggests not only ranking accuracy, but also quantitative risk realism.

To test whether results were driven by subtle temporal artifacts, the team ran sensitivity analyses that excluded events occurring shortly before prediction and varied washout windows. They also examined alternative horizons and a dynamic 10-year rolling interpolation strategy, which updates risk estimates as annual information becomes available. Together, these checks help confirm that temporal patterns are being learned in a causally aligned manner.

Overall, the findings position ALADYNOULLI as a clinically relevant framework for multi-disease risk forecasting, combining longitudinal EHR modelling with predictive discrimination and calibration. By rigorously preventing leakage and validating dynamic follow-up scenarios, the approach offers a pathway toward more actionable, time-aware risk prediction in real-world healthcare settings.

A hummingbird, a beetle, and a human may inhabit the same moment, but according to new research, each species experiences that moment unfolding in a fundamentally different way.

While scientists have traditionally measured animal time perception using simple metrics like flicker detection, a new study argues that such approaches capture only a fraction of how creatures experience reality. Instead, the researchers propose that every species inhabits its own unique “timescape,” shaped by biological processes that govern how sensory information is assembled, updated, remembered, and interpreted.

Understanding these distinct temporal worlds, they say, could provide new insights into animal behavior, consciousness, and the evolution of perception itself.

Quantifying the Experience of Time

Jakob von Uexküll, an early 20th-century German zoologist, developed the idea that different animals experience reality in their own unique bubble, dictated by their biology’s unique combination of sensory inputs and processing. From the German word for “environment” or “surroundings,” he called the unique sensory experience of each animal an “Umwelt.”

In previous work, the critical flicker fusion threshold (CFFT), which measures the Hz at which a creature perceives a flickering light as steady and continuous, was used as the sole metric to quantify how animals perceive visual content over time, but the researchers say this is far too shallow a standard.

CFFTs occur in a broad range of frequencies between 4 and 500 Hz, which the researchers say could give a false impression of the rate at which experiences flow for other creatures. The authors note that “Even in humans, CFFTs are uninformative about the temporal regularities over which our perceptual mechanisms anticipate, organize, revise, or attend to perceptual inputs.”

The issue, they say, is that CFFTs only measure retinal sensitivity, not how a creature cognitively experiences timescales. This can lead to the false assumption that certain animals perceive time more rapidly than others, but that may be incorrect without accounting for the full cognitive picture.

A More Complete View

Looking beyond CFFTs alone, the team identified five Umwelts to understand the biological elements of animal experience, which include: synchronization, revision, attention, persistence, and stability. They define synchronization as how an animal puts together the pieces of a single moment, revision as how perception is updated with fresh input, attention as how long focus remains on a single thing, persistence as how long content remains after a stimulus offset, and stability as how long it takes for perception to switch.

The researchers note that various studies have shown that single species display remarkably different performance measurements across these tasks, suggesting that, rather than relying on a single metric, such as CFFTs, to define how granularly an animal perceives time, different species exhibit distinct temporal experience organizations.

According to the team, temporal illusions are important for understanding how these elements vary in different species. By understanding where perception of time goes astray between input and recognition, researchers can gain a better idea of the processes the animal uses to construct its perception of time.

Time’s Illusions

These types of sensory illusions typically occur within a 100-450 millisecond time range in humans, such as apparent motion. When an object moves relative to the eye in such a brief time, it can appear to move even when it is stationary, an experience common to both vertebrate and invertebrate species. These illusions also occur in the auditory systems and the tactile systems that interpret an animal’s nervous system signals.

The researchers say that these Umwelts could be the root of understanding the phenomenology of time perception in animals. By better understanding these metrics, researchers could develop models of how they relate to one another and possibly even uncover aspects of temporal experience that don’t exist in humans.

Altogether, the researchers say their work can be used to explore consciousness from empirical, theoretical, and philosophical perspectives, and can also contribute to ecology by helping us better understand animals and their relationships to their environment, as well as the predator/prey relationship.

Additionally, a better understanding of these temporal experiences could inform infrastructure design, such as reducing avian collisions with wind turbines by increasing blade visibility to various bird species.

Researchers investigate how quantum time flow can be stretched, blurred, or even reversed. What if the direction of time isn’t as fixed as it seems? While our everyday experience tells us that time moves relentlessly forward, the microscopic laws governing quantum systems are far less restrictive. In fact, many of the equations of quantum mechanics [...]

In a groundbreaking advancement poised to redefine core principles in theoretical physics, researchers from Kyushu University and esteemed international collaborators have unveiled insights into the nature of continuous parameters within quantum gravity. This study challenges the long-standing assumption that such parameters are freely adjustable external inputs by demonstrating—under particular theoretical conditions—that they inherently originate from operators embedded within the physical theory itself. This resolution not only revitalizes Albert Einstein’s century-old assertion regarding the intrinsic completeness of physical laws but also propels forward our comprehensive understanding of the quantum structure of spacetime.

Central to this revelation is the concept of exactly marginal operators within the framework of conformal field theory (CFT), a pivotal branch of modern physics that explores systems invariant under scale transformations. CFT serves as a formidable bridge between quantum theory and gravitational physics, especially through the lens of the anti-de Sitter/conformal field theory (AdS/CFT) correspondence. This correspondence posits a deep equivalence between gravitational theories in a curved AdS spacetime and lower-dimensional CFTs residing at its boundary, rendering CFT an indispensable tool to probe quantum gravity’s elusive traits.

At the heart of the research lies the structure known as the conformal manifold—an abstract space parameterizing a continuous family of CFTs interconnected via exactly marginal deformations. These deformations represent operators that tweak a theory’s parameters without sacrificing its conformal symmetry. The pressing theoretical puzzle was whether the existence of such a manifold necessarily implies that continuous variations in the theory’s parameters emerge from operators already encoded within the theory, rather than arbitrary, external parameters appended to the formalism.

To rigorously examine this, the interdisciplinary team led by Associate Professor Yuya Kusuki embraced an innovative approach involving conformal interfaces, mathematical constructs that serve as boundary layers interpolating between two related CFTs situated on a conformal manifold. The researchers posited that as two nearby CFTs approach equivalence, the conformal interface connecting them should become trivial. Under the plausible assumption that certain correlation functions transition smoothly as this interface dissolves, they utilized the interface’s displacement operator—which quantifies the response of the interface to infinitesimal positional shifts—to reconstruct an exactly marginal operator governing motions on the manifold.

This reconstruction represents a monumental stride because it conclusively ties continuous parameters characterizing a family of theories not to arbitrary external dials but to concrete operators intrinsic to the theory’s internal dynamics. By examining the perturbative behavior of the conformal interface, the team effectively identified the fundamental origin of parameters that might otherwise have seemed freely tunable.

What does this imply for the broader quest of quantum gravity? Through the prism of AdS/CFT duality, the intimate relationship between conformal manifolds in CFT and the moduli space of vacua in quantum gravity theories becomes transparent. This newly established principle supports the profound conjecture that quantum gravity forbids arbitrary external parameters, with all continuous couplings traceable to internal degrees of freedom—a concept resonant with a widespread expectation but hitherto unproven with such clarity.

Importantly, the present findings apply specifically to two-dimensional CFTs, a fertile domain where theoretical control is well established. Nevertheless, the researchers have expressed optimism that their methods and conceptual revelations will motivate extensions to higher-dimensional CFTs and more general quantum gravity landscapes. Extending these results could illuminate the landscape of string theories and the parameters governing candidate quantum gravity models.

Moreover, these results have significant implications for the so-called “Swampland program,” a burgeoning field striving to delineate which consistent-looking effective field theories can be embedded into quantum gravity. By constraining continuous deformations to those generated by internal operators, this study offers fresh constraints on the space of viable theories and sharpens the boundaries between the “landscape” of consistent theories and the “swampland” of inconsistent ones.

The research underscores an increasingly vital notion: the parameters defining fundamental physics are not arbitrary selections but emergent phenomena anchored within the theory’s operator framework. This insight advances a vision in which the fabric of physical law is self-contained, avoiding unexplained fundamental constants, and aligning with Einstein’s aspiration for a theory without ad hoc inputs.

Led by Kusuki alongside collaborators Shota Komatsu of CERN, Marco Meineri from the University of Turin, and Hirosi Ooguri of the California Institute of Technology, the project utilized sophisticated computational simulations combined with analytic operator algebra techniques to bring these abstract mathematical objects into clearer physical focus.

Published in the prestigious journal Physical Review Letters on June 16, 2026, the paper titled “Continuous Family of Conformal Field Theories and Exactly Marginal Operators” delineates these technical breakthroughs and their broader theoretical implications, offering a compelling blueprint for future explorations in the intersection of quantum theory and gravity.

As the physics community absorbs the ramifications of this breakthrough, it heralds a renewed momentum for using conformal field theory and holographic dualities as guiding principles to unravel the enigmatic quantum nature of gravitation, spacetime, and the universe’s foundational constants.

In recent years, the global medical community has observed an alarming rise in the incidence of congenital hypothyroidism (CH), a condition characterized by insufficient thyroid hormone production in newborns. This endocrine disorder, if undiagnosed or untreated, can lead to profound developmental delays and intellectual disabilities. Against this backdrop, a landmark study published in Pediatric Research sheds new light on the long-term administration and cessation patterns of levothyroxine—a synthetic thyroid hormone replacement—in patients assumed to have CH. This nationwide cohort investigation, spanning over a decade, provides unprecedented insights into treatment paradigms and patient management on a population scale.

The study meticulously tracked levothyroxine usage across a broad demographic, encompassing thousands of newborns clinically suspected of congenital hypothyroidism. Using comprehensive health databases, researchers were able to delineate initiation rates, dosage adjustments, duration of therapy, and the critical junctures at which discontinuation occurs. They highlight how early diagnosis, often through neonatal screening programs, has revolutionized patient outcomes but also raised new questions regarding optimal treatment length and criteria for safely discontinuing therapy.

One of the foundational aspects explored in this investigation is the temporal trend of levothyroxine initiation. The data convincingly demonstrate a marked increase in the frequency of diagnoses and subsequent treatment initiation over the 10-year observation period. This escalation aligns with heightened screening sensitivity and revised diagnostic thresholds, suggesting that what was once considered atypical or borderline hypothyroidism is now more frequently targeted for intervention. Such shifts bring about complex clinical decisions around the balance between necessary hormone supplementation and potential overtreatment.

In delineating the course of levothyroxine administration, the study underscores that a significant subset of patients undergoes treatment discontinuation, reflecting evolving clinical judgments based on follow-up evaluations. These discontinuations often result from confirmatory testing that challenges the initial diagnosis or reveals transient hypothyroidism, a condition that resolves spontaneously without lifelong hormone dependency. Understanding when and how to discontinue therapy safely remains a cornerstone in preventing unnecessary treatment burden and its accompanying risks.

Moreover, the investigation probes into the demographic and clinical determinants influencing levothyroxine discontinuation. Variables such as age at diagnosis, initial thyroid function test results, and the presence of thyroid dysgenesis or dyshormonogenesis significantly sway therapeutic decisions. The study’s granular stratification reveals that patients with milder biochemical abnormalities or transient hypothyroidism are more likely to cease treatment within the first few years of life, emphasizing the importance of individualized care pathways.

Intriguingly, the analysis also touches upon the challenges in differentiating permanent congenital hypothyroidism from transient cases during the neonatal period. These diagnostic ambiguities are amplified by biochemical fluctuations, maternal thyroid conditions, and environmental factors such as exposure to iodine or goitrogens. The study’s extensive dataset allows for a nuanced understanding of these confounders, paving the way for refined diagnostic algorithms and personalized monitoring protocols.

The ramifications of sustained levothyroxine therapy extend beyond hormone replacement; they encompass metabolic, cardiovascular, and neurodevelopmental domains, especially if treatment is misaligned with the patient’s true thyroid status. Over-replacement can lead to iatrogenic thyrotoxicosis, while under-treatment perpetuates hypothyroid sequelae. This cohort study underscores the imperative for vigilant clinical and biochemical monitoring, leveraging advances in assay technologies and genetic profiling to tailor interventions precisely.

From a public health perspective, the rising levothyroxine use in presumed CH presents implications for healthcare resource allocation, long-term follow-up infrastructure, and parental counseling. National screening programs must adapt to integrate not only early detection but also robust tracking systems that ascertain treatment necessity, effectiveness, and safety over time. This study’s nationwide scope lends critical data to guide policy refinements and equity considerations in thyroid disease management.

Furthermore, the researchers advocate for a paradigm shift towards dynamic therapeutic frameworks, where treatment initiation is complemented by scheduled re-evaluations to determine the persistence of hypothyroidism. By promoting trial discontinuations under strict supervision, clinicians can limit unnecessary exposure to levothyroxine, thereby mitigating potential adverse effects and preserving health system sustainability.

Equally important, the study highlights gaps in current clinical guidelines, which often lack consensus on precise criteria for levothyroxine cessation. These ambiguities contribute to variability in practice and patient outcomes. The authors call for concerted efforts among endocrinologists, neonatologists, and healthcare policymakers to develop evidence-based protocols informed by longitudinal data such as theirs.

In terms of methodology, the utilization of expansive health claims and prescription data validates the reliability and real-world applicability of the findings. The analytical approach, employing survival analysis and multivariate regression modeling, unravels complex patterns of drug utilization and discontinuation, while adjusting for confounding factors. This rigorous epidemiological framework sets a benchmark for future pharmacoepidemiological research in pediatric endocrinology.

It is also noteworthy that the study addresses psychosocial dimensions indirectly, recognizing that parents and caregivers play pivotal roles in adherence and decision-making regarding levothyroxine therapy. Long-term treatment regimens can strain families emotionally and financially, underscoring the need for supportive care models and transparent communication strategies.

The implications of the rising incidence of CH—and correspondingly, levothyroxine use—also evoke considerations about environmental and genetic influences driving this trend. Although not the primary focus, the comprehensive data collected may inspire ancillary investigations into prenatal exposures, epigenetic modifications, and population-based genetic predispositions contributing to this public health challenge.

Ultimately, this landmark investigation by Kim, Woo, Lee, and colleagues portrays a nuanced portrait of levothyroxine use in presumed congenital hypothyroidism, emphasizing the dual imperatives of timely treatment and judicious discontinuation. Their ten-year nationwide cohort analysis unearths critical trends that will undoubtedly inform clinical practice, guideline development, and health policy designed to optimize outcomes for affected infants and children worldwide.

As pediatric endocrinology advances, the insights gleaned from this study serve as a timely reminder of the complexity underlying ostensibly straightforward diagnoses. The nuanced interplay between biochemical parameters, diagnostic certainty, patient heterogeneity, and long-term treatment strategies requires clinicians to balance evidence-based medicine with individualized care. This study not only contributes pivotal epidemiological evidence but also catalyzes a re-examination of management philosophies in congenital hypothyroidism.

In conclusion, the increasing incidence of congenital hypothyroidism and the corresponding escalation in levothyroxine use illuminate a critical area for continued research and healthcare innovation. The ten-year nationwide cohort study effectively captures the evolving landscape of diagnosis, treatment, and discontinuation, reinforcing the need for integrated multidisciplinary approaches. By fostering personalized medicine approaches grounded in large-scale data analysis, healthcare systems can aspire toward improved thyroid health in newborns and beyond.
