Pitt researchers engineered the harmless eye bacterium Corynebacterium mastitidis to secrete interleukin-10, creating a 'living eye drop' that accelerated corneal healing in mice and showed promise in human cell tests.

Fewer than 10% of older adults with advanced cancer prioritized extending survival over quality of life, yet their stated preference was not associated with differences in treatment modifications or outcomes, a JAMA Oncology study finds.

A comparative effectiveness study published in JAMA Otolaryngology finds that reducing music volume in group fitness classes did not meaningfully change how hard participants felt they were working, supporting safer sound practices.

Growth marks in crocodile bones can dramatically overestimate age, a finding that has direct implications for how paleontologists estimate the lifespans and growth rates of dinosaurs and other extinct vertebrates.

The American Educational Research Association has announced its 2026 award recipients, recognizing 16 researchers and journalists across 14 categories for contributions to education research, equity, and public communication.

A Kobe University study finds that Japanese red elder trees drop beetle-infested fruits not as punishment but as a compromise: the plant saves resources while the larvae survive by burrowing into soil to complete development.

Researchers at Xidian University have built photonic spiking neural network chips that perform both linear and nonlinear computation in the optical domain, achieving reinforcement learning with on-chip latency of just 320 trillionths of a second.

A new report to CMS COP15 finds that 49% of migratory species populations protected under the UN treaty are declining -- up 5 percentage points in just two years -- while 24% now face extinction risk.

A meta-analysis of 20 studies covering more than 220,000 infants finds that about one in 20 babies worldwide experiences physical aggression from a caregiver before age two -- rates far higher than official records suggest.

Two new studies quantify the risks of getting your tongue stuck to frozen metal, using 84 pig tongues and 856 Scandinavian media reports dating to 1845. In 54% of experiments, tissue was torn when the tongue was pulled free.

New research from Tufts University maps C. diff behavior at the single-cell level and identifies a protein complex that controls when dormant spores reactivate, offering two potential targets for better treatments.

Scientists have grown and harvested chickpeas in mixtures of up to 75% simulated lunar soil by adding worm compost and symbiotic fungi, marking the first time this crop has been produced in such a medium.

Teens who frequently lash out at others show signs of faster biological aging by 30, but only when early aggression leads to sustained relationship conflict through adulthood, a new study in Health Psychology finds.

A systematic review of 56 studies across 63 countries confirms that large-scale food fortification is among the most cost-effective public health interventions available, with the majority of programs delivering benefits that far outweigh costs.

A new special edition of Philosophical Transactions of the Royal Society B presents the first thorough collection of peer-reviewed research on managing diseases in marine wildlife, from sea star wasting to avian flu in seals.

The LVK collaboration's latest catalog adds 128 gravitational-wave events from just nine months of observing, more than doubling the previous total and exposing an unexpectedly rich variety of black hole collisions.

The LIGO-Virgo-KAGRA collaboration has released its largest gravitational-wave catalog yet, adding 128 new detections that more than double the previous total and reveal an unexpectedly diverse population of colliding black holes.

In a study published in Science, researchers found that ovarian fibrosis physically traps dormant follicles. The antifibrotic drug finerenone reduced collagen in ovarian tissue, restarting follicle development in mice and producing mature oocytes in 7 of 14 women with premature ovarian insufficiency.

A study in mice and humans with chronic apical periodontitis reveals that excess copper binds to histone proteins and silences the enzyme GYS1, disrupting glycogen synthesis and driving macrophages to become bone-destroying osteoclasts. The cuproptosis inhibitor tetrathiomolybdate reversed the effect.

Tokyo University of Science researchers created irregularly shaped nano-sized microplastics from common plastics (PET, polypropylene, polyethylene, polystyrene), loaded them with fluorescent dye, and tracked their journey through mice in real time. The particles stayed in the gut and were excreted, with smaller particles lingering longest.

A collaboration between OIST and the Karlsruhe Institute of Technology has produced Antscan, a freely available database of over 2,000 high-resolution 3D ant models spanning 800 species. The workflow scanned specimens in days rather than years, offering a blueprint for digitizing biodiversity at scale.

Using a synchrotron particle accelerator, robotics, and AI, researchers scanned 2,000 ant specimens in one week -- a process that would have taken six years with conventional equipment. The resulting Antscan database, covering 800 species, is freely available and reveals internal anatomy at micrometer resolution.

ESA's Mars Express and Trace Gas Orbiter captured the May 2024 solar superstorm's impact on Mars using orbiter-to-orbiter radio occultation. Electron densities in the upper atmosphere surged by up to 278% -- the highest ever recorded there -- while both spacecraft experienced computer glitches from the radiation.

Using scanning electrochemical cell microscopy for the first time on thermochemical reactions, researchers at Warwick and MIT mapped activity across a platinum catalyst surface with unprecedented detail, finding coordinated electron flows between crystal grains rather than independent reaction sites.

In a system deliberately designed to be slow, Cambridge researchers watched an electron cross a material boundary in just 18 femtoseconds -- driven not by electronic coupling but by coherent molecular vibrations acting as a catapult. The finding challenges core assumptions in organic solar cell design.
