Analyzing 5 million live births across 33 sub-Saharan African countries and India, researchers found days above 20 degrees C reduce male births - but through distinct biological and behavioral pathways that differ sharply by region.
Read the releaseWashington University scientists found disrupted lymphatic vessels after heart and lung transplants trigger chronic fibrosis through hyaluronan buildup - independent of immune rejection. Three interventions in mice prevented the damage entirely.
Read the releaseWashington University researchers studying mice on a ketogenic diet found hundreds of gene expression changes in the hippocampus, reduced excitatory synaptic signaling, and physically fewer vesicles containing excitatory neurotransmitters - providing a cellular mechanism for the diet's known anti-seizure effects and pointing toward potential drug targets.
Read the releaseA University of Michigan-led methodology using ion beams to simulate radiation damage in nuclear reactor materials - achieving in days what test reactors require over a decade - is advancing through ASTM industry standards approval as QUICC (Qualification under Ion irradiation of Core Components), with potential to dramatically accelerate materials testing for advanced reactor designs.
Read the releaseA University of Washington analysis of 132 disease categories from 1996 to 2016 found U.S. medical care improvements added 1.3 healthy years per person at a lifetime cost of $234,000 - or $182,000 per healthy year gained - with massive variation from $451 per year for stroke improvements to net losses for drug use disorders.
Read the releaseThe 2026 SPIE Advanced Lithography + Patterning conference highlighted a striking duality: AI's demand for ever-more-capable chips is straining semiconductor manufacturing, while AI-driven process control is simultaneously becoming the primary tool for managing the resulting complexity.
Read the releaseA Michigan State University study published in npj Complexity found that AI agents programmed to mimic human behavior within a Public Goods game lowered the cooperation threshold and produced more collective contribution than agents programmed to always cooperate or that were controlled by human players - but real-world applicability remains speculative.
Read the releaseUC Irvine computer scientists demonstrated that a specially patterned umbrella can fool autonomous tracking drones into believing their target is moving away, drawing the aircraft within capture or crash range. The FlyTrap attack succeeded against three commercial drones and has been disclosed to manufacturers DJI and HoverAir.
Read the releaseA Korean study of more than 410,000 adult smokers found that persistent smokers had the lowest Parkinson's disease incidence, while sustained quitters showed 60-61% higher risk of Parkinson's - yet sustained quitters also had 17% lower overall mortality, reinforcing the broad health case for quitting despite the Parkinson's paradox.
Read the releaseUsing data from 223 male participants including 170 former college and professional football players, researchers found higher levels of interleukin-6, TNF-alpha, and GFAP associated with worse white matter microstructure in the limbic system, which predicted poorer memory - suggesting inflammation as a potential pathway from head impacts to cognitive decline.
Read the releaseA study of over 500,000 people followed for 14 years found morning chronotype associated with 20% lower ALS risk and 600+ MET-minutes per week of physical activity associated with 26% lower risk compared to night owls and less active individuals - though 95% were white and causation cannot be established.
Read the releaseThe Lancet's ARTISTRY-1 phase 3 trial data shows bictegravir/lenacapavir single-tablet therapy maintained HIV suppression in 96% of 550+ patients aged 22-84 on complex multi-drug regimens, with improved cholesterol profiles and no new drug resistance.
Read the releaseThe ARTISTRY-1 phase 3 trial of 550+ people across 15 countries found that a single daily tablet combining bictegravir and lenacapavir maintained HIV viral suppression in nearly 96% of participants switching from complex multi-pill regimens, with improved lipid profiles and no new drug resistance.
Read the releaseAnalysis of 607,315 gun homicide deaths from CDC data spanning 1979 to 2023 found the racial disparity in firearm homicide rates widened significantly after 2010, reaching 10.38 times higher for Black males versus White males in 2020, with 31,202 excess Black deaths in 2021-2023 alone.
Read the releaseAn online experiment with 1,051 U.S. adults found that flagging posts containing false cancer treatment claims as potentially inaccurate reduced participants' stated intent to share the content, suggesting targeted labeling may partially counter health misinformation on social platforms.
Read the releaseUltrasound monitoring of 32 healthy fetuses found an average of 3.63 yawns per hour, with higher yawning frequency correlating with lower birth weight - a potential marker of mild fetal stress, even when all infants were born healthy.
Read the releaseA field trial in the Ethiopian highlands compared conventional tillage against conservation agriculture practices including no-till, crop rotation, and mulching. The conservation approach reduced water runoff and soil erosion while increasing crop yields by up to 122%, offering a practical model for degraded smallholder farming systems.
Read the releaseAnalysis of over 8,000 herbarium specimens collected between 1794 and 2024 across 33 tropical species shows flowering periods have shifted by an average of two days per decade, with some species shifting by weeks or months - challenging assumptions that tropical plants are insulated from climate-driven phenological change.
Read the releaseAnalysis of 25 years of data shows humpback whale entanglements in West Coast fishing gear spike during years of compressed cold-water habitat, with the Habitat Compression Index able to predict ocean conditions 6-12 months in advance - offering managers an early warning tool.
Read the releaseComputer modeling of climate and milkweed distribution projects an 8-40% decline in suitable monarch butterfly habitat across Mexico by 2070, with the remaining habitat concentrating in southern Mexico and fracturing existing north-south migration corridors.
Read the releaseCarnegie Mellon scientists analyzed response-time variations and error patterns during awake brain tumor surgery, finding that stimulation timing and duration produce measurable but previously overlooked behavioral signals that could enable more personalized surgical decisions.
Read the releaseA cross-sectional analysis of 1,998 adolescents from the 2021-2023 NHANES cycle found nearly one in three met criteria for prediabetes or type 2 diabetes, with waist-to-height ratio outperforming BMI as the strongest independent predictor of metabolic risk.
Read the releaseVirginia Tech researchers used gene editing to disable a single phosphorylation site on the AMPK enzyme in mice. The animals ran only one-third as far as controls, and AMPK-related protein patterns in their muscles matched data from human diabetic patients - pointing toward a potential diabetes treatment target.
Read the releaseSyracuse University chemists demonstrated a proof-of-concept system that holds cancer drug molecules in an inactive 'caged' form using biorthogonal supramolecular chemistry. A separate trigger molecule releases the drug at a specified site in cell-based experiments - with a key stability challenge still to solve.
Read the releaseA Columbia University study of 104,231 U.S. adults found benzodiazepine use fell from 4.7% in 2018 to 3.4% in 2022, with the sharpest drop among adults 56 and older. But 41.6% of current benzodiazepine users also received another CNS depressant - rising to 72% among those in poor health.
