Whitehead Institute and Max Planck researchers discovered that cells require two separate RNA signals - like a biological two-factor authentication - before destroying specific microRNAs, explaining how cells avoid accidentally dismantling their own gene regulation.

Two Nature studies using multi-million-year-old Antarctic ice show that CO2 remained below 300 ppm over the past 3 million years, while ocean temperatures dropped 2 to 2.5 degrees Celsius - raising new questions about what drove Earth's long-term cooling.

Women who reach natural menopause before age 40 face roughly 40% higher lifetime coronary heart disease risk, regardless of race, with Black women three times more likely to experience this early hormonal shift.

A phase 1 trial across the U.S. and South Africa found that a multi-strain Lactobacillus crispatus probiotic colonized two-thirds of participants within five weeks and significantly reduced bacterial vaginosis recurrence.

Women who enter natural menopause before age 40 carry a 40% higher lifetime risk of coronary heart disease, according to a study of more than 10,000 women that also found Black women are three times more likely to experience premature menopause.

Psychedelic-assisted therapy was no more effective than open-label traditional antidepressants in a new analysis that accounts for the near-impossible task of blinding participants in psychedelic trials.

A new analysis comparing psychedelic-assisted therapy to open-label antidepressants finds virtually no difference in effectiveness for major depression, suggesting the hype around psychedelics may outpace the evidence.

UCSF Health has earned The Joint Commission's Advanced Certification in Spine Surgery, joining just 46 hospitals nationally and five in California. The voluntary designation required standardizing care across neurosurgery and orthopaedic surgery departments over more than two years.

A new review uses molecular docking to show resveratrol binds four key ovarian cancer-associated proteins with strong affinity. But no direct clinical trials in ovarian cancer exist yet, and the compound's poor bioavailability remains a major hurdle.

A new editorial in Aging-US argues that geroscience should adopt health-adjusted longevity as its primary metric, stop treating lifespan and healthspan as competing goals, and commit to moonshot-level investment in aging biology research.

Researchers studying Galapagos yellow warblers found that females sing frequently, mostly during non-breeding season and almost always as duets with their mates. But the singing showed no link to aggression or territorial defense, suggesting female birdsong serves a different, still-unknown purpose.

JMIR Publications and the University of Helsinki have signed a flat-fee agreement for 2026 that gives all affiliated researchers unlimited open-access publishing across JMIR journals, replacing individual article processing charges with a single institutional payment.

A Northwestern-led team measured the spin rates of six giant exoplanets and 25 brown dwarfs using Keck Observatory, finding a clear pattern: giant planets rotate at a larger fraction of their maximum possible speed than brown dwarfs, suggesting different formation histories.

A Jackson Laboratory study in Cell Reports finds that PD-L1 - normally blocked to fight cancer - actually helps immunocompromised mice survive influenza by enhancing natural killer cell function. The discovery suggests checkpoint pathways may work differently depending on which cells carry them.

A new review in Clinical Microbiology Reviews finds nursery-age children may catch 12-15 respiratory infections annually but develop stronger immunity that reduces illness in early school years. The five authors are all parents of young children.

The Endocrine Society has named five winners of its 2026 Early Investigator Awards. The recipients, spanning institutions from Harvard-affiliated hospitals to the University of Texas, study topics including pituitary tumors, endocrine-disrupting chemicals, and continuous glucose monitoring.

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.
