A Dartmouth team has built a phone-based tool that measures tissue oxygen - not blood oxygen - using a topical cream, pulsed LED light, and a standard smartphone camera. The system could let patients monitor limb health and wound healing at home.

Researchers from China's South China Botanical Garden and Australia's Royal Botanic Gardens Victoria make the case that botanical gardens are not luxury green space but essential urban infrastructure for biodiversity conservation, mental health, and climate adaptation.

A Florida Atlantic University biologist developed a simple, low-cost device that generates a mild electric field on fishing hooks to deter sharks while leaving target species unaffected - and commercial fishermen are already testing it at sea.

A digital twin brain framework uses a person's resting-state brain connectivity to predict behavioral choices, reaction times, and brain activation patterns across cognitive and emotional tasks - then simulates how targeted interventions might alter specific functions.

New research reveals that amyloid beta and tau bind microtubules with roughly equal strength, meaning excess amyloid beta can displace tau from its stabilizing role - potentially triggering the transport breakdown that leads to neurodegeneration.

Researchers developed prototype breath tests using carbon-13-labeled sugars that bacteria consume but human cells ignore, detecting pneumonia, bloodstream, muscle, and bone infections in mice within 10 minutes of administration.

A compound derived from the snail Camaena cicatricosa blocked harmful clot formation in mouse models of deep vein thrombosis without increasing bleeding risk - a critical limitation of heparin, the century-old anticoagulant standard.

ESMT Berlin research shows that salespeople avoid pushing novel products because they dread being unable to answer customer questions - a fear of losing face that cuts sales performance regardless of how strong the product actually is.

By reverting five unnecessary mutations in an older base editor, researchers created ME-ABE - a tool that maintains a narrow editing window and high efficiency, solving a longstanding tradeoff that has complicated gene therapy safety.

The SuperCDMS experiment at SNOLAB in Ontario has reached its operating temperature - hundreds of times colder than outer space - marking the transition from construction to active science as researchers prepare to search for lightweight dark matter particles.

A UC San Diego-led team demonstrated that acoustic waves can controllably move mechanical kinks - boundaries between soft and stiff regions - through a specially designed material, creating what amounts to remote control over how a material feels and behaves.

A new data platform harmonizes nearly 10 million electronic health records across three U.S. health systems to study how multiple chronic diseases, behaviors, and social factors interact over time to shape Alzheimer's risk - moving beyond single-disease models of dementia.

Nearly half the world carries H. pylori, a bacterium linked to stomach cancer. TUM researchers found that metronidazole targets two key protective proteins, then created a chemical variant 60 times more potent that also cleared infection in mice at very low doses while preserving gut bacteria.

A quick nasal swab collected living nerve and immune cells whose gene activity patterns separated early and clinical Alzheimer's from healthy controls with 81% accuracy - potentially catching the disease before symptoms appear, when new treatments may work best.

University of Pennsylvania engineers created a lipid nanoparticle that simultaneously blocks the immune-suppressing enzyme IDO and delivers mRNA for the immune activator IL-12. In mice, the approach eliminated established colon tumors, prevented recurrence, and triggered body-wide anti-tumor immunity.

MIT neuroscientists found that mice with a mutation in grin2a - a gene linked to schizophrenia in large human studies - are significantly slower to adapt their decisions when reward conditions change, due to impaired signaling in a thalamus-to-cortex circuit.

Protein sequencing has lagged far behind DNA sequencing in speed and scale. Stanford bioengineers developed a chemistry that converts protein sequences into DNA barcodes, potentially seeing 1,000 times more molecules than mass spectrometry from the same sample.

University of Konstanz physicists built a system where two magnetic layers generate friction without ever touching. The friction peaks at intermediate distances rather than increasing steadily with load, violating Amontons' law - one of the oldest rules in physics.

Less than 2% of nitrile rubber gets recycled. Chemists at St Andrews developed two catalytic routes that convert used nitrile gloves into polyamines and polyols - useful industrial chemicals - with the polyamines also capable of capturing carbon dioxide from emissions.

When HER2-positive breast cancer spreads to the fluid surrounding the brain, patients typically survive less than five months. A new Phase II trial from MD Anderson found a three-drug regimen more than doubled median survival to 10 months, with 41% of patients alive at 18 months.

A cold freshwater layer beneath Antarctic sea ice had shielded it from warm deep water for decades. University of Gothenburg researchers show that layer thinned gradually, then collapsed during fierce 2015 storms, triggering rapid ice loss that persists today.

A comprehensive carbon budget from a Swiss stream corridor shows beaver-engineered wetlands accumulated 1,194 tonnes of carbon over 13 years - storing CO2 at rates up to ten times higher than comparable systems without beavers, while methane emissions accounted for less than 0.1% of the total budget.

Scientists measured mid-infrared reflectance in bird feathers for the first time, finding that visually identical ravens absorb heat differently by subspecies, while open-habitat bobwhites show the most variation in thermal emittance - suggesting feathers evolve for heat management invisible to the eye.

Entomologists have formally described Andrena cenizophila, a mining bee from southwest Texas and northern Mexico that collects pollen exclusively from cenizo (Texas purple sage) during its brief, rain-triggered blooms - making it the only known mining bee specialized on this shrub.

Researchers at King's College London and the University of Surrey developed a method to select and chemically analyze single human cells infected with TB-model bacteria, revealing metabolic differences between infected and uninfected macrophages invisible to conventional bulk analysis.
