When a home burns, toxic volatile organic compounds spike compared with forest fires - but only for certain chemicals. A Colorado study burning 18 building materials shows synthetic materials drive specific hazards while wood dominates the total emission picture.

Structural analysis of Phytophthora RxLR effectors reveals that short linear interaction motifs can sit inside stable folded protein domains rather than disordered regions - a finding that reframes how plant immunity researchers design functional experiments.

Carl Bergstrom and Kevin Gross used mathematical models to show that declining peer review quality and rising submission volumes form a self-perpetuating cycle. Paying reviewers, reducing submission incentives, and restructuring academic promotion criteria are among the interventions they identify as potentially stabilizing.

A new mathematical model from the University of Illinois shows how microbial communities built on mutual nutrient dependence become more stable in fluctuating environments - and correctly predicted which three of four E. coli strains would survive to form a stable community in an independent lab experiment.

A peer-reviewed Chapman University study analyzing satellite data, hydrological models, and geospatial analysis at Ethiopia's Grand Renaissance Dam found an estimated 41 to 6.2 billion cubic meters of seepage, up to 40mm of differential settlement, and potential downstream flood depths of 34.7 meters if the saddle dam were to breach.

Male Drosophila flies rely on specific visual cues - particularly the female's eyes - to determine her body orientation and direct different courtship behaviors to different parts of her body. A machine-learning study published in G3 shows vision plays a more spatially precise role in fly courtship than previously thought.

Columbia University received an ARPA-H award to identify measurable biological signals of aging deceleration from existing clinical trial data. Early findings suggest rapamycin may slow ovarian aging by roughly 20 percent - potentially extending fertility by up to five years.

Lab experiments using real Arabian Gulf oxygen profiles show that Gulf blenny reef fish use about 3% more energy per day when exposed to nighttime low-oxygen events. Those events occur on more than half of all summer nights - and the region's extreme heat makes fish especially vulnerable to compounding stress.

When COVID forced 90% of museums to close in 2020, educators scrambled online with almost no relevant research to guide them. A 2023 survey found 81 of 100 respondents still running online programs - mostly K-12 focused - but fewer than 15% had attended relevant conferences and more than half wanted more training.

When extreme rain triggered flooding in Quebec's Charlevoix region in 2011, courts found municipalities liable for failing to remove beaver dams. New LiDAR-based hydraulic modeling shows the dam failures raised water levels at the damaged property by only 20 centimeters for a few minutes - and the flooding would have happened regardless.

Fiberglass particles appeared in 96% of sediment sites sampled at the Cowichan Estuary in 2023, up from 64% in 2020. The 400-hectare intertidal area supports migratory shorebirds, shellfish harvesting, and Cowichan Tribes First Nations food security - making contamination an urgent management concern.

In a six-year study of 46 Arctic seabird chicks, shorter early-life telomeres predicted a higher probability of returning to the natal colony as adults - the opposite of standard expectations. In competitive sibling conditions, investing in growth appears to beat investing in DNA repair.

Of 1,567 shed antlers examined from Alaska's Arctic National Wildlife Refuge, 86% showed gnaw marks and 99% of those marks were made by caribou. The finding offers a compelling answer to why female caribou evolved antlers: to bring calcium and phosphorus to calving grounds and consume them when nursing demands peak.

To engineer yeast into reliable drug-delivery vehicles, scientists needed to understand which genes activate when yeast enters the gut. An NC State study using germ-free mice provides that roadmap - and finds the gut is nutrient-poor for yeast in ways that affect engineering strategy.

Carbon-nitrogen bonds are essential to nearly every pharmaceutical. Making them efficiently has required expensive platinum and palladium - until UCLA chemists found that light-activated phosphorus can do the same job through a different mechanism, potentially lowering drug manufacturing costs.

Submission rates to scientific journals are rising faster than available peer reviewers can absorb. New mathematical modeling in PLOS Biology maps the feedback cycles driving this deterioration and identifies which interventions could actually stabilize the system.

Analyzing all professional recordings of a rediscovered 19th-century Ethel Smyth piano miniature, a Surrey researcher found that performers diverged radically with no shared tradition to guide interpretation - a problem that will grow as more marginalized composers are brought back into the repertoire.

Ochsner Baton Rouge has added eight new physicians and advanced practice providers across neuropsychology, ENT, family medicine, OB-GYN, and psychiatric nursing - all now accepting new patients at clinics in Baton Rouge, Prairieville, and surrounding parishes.

HIV hides in one-in-a-million immune cells that have resisted every cure attempt. Scientists have now isolated and grown these authentic reservoir clones in the lab, discovering that sustained immune pressure can slowly erode most of them - and that an FDA-approved drug can weaken resistant survivors.

Existing climate policies saved 3 billion tons of CO2 in 2022 - roughly the European Union's annual emissions. A new multi-institution study identifies which policy designs worked and which fell short across the world's 43 largest economies.

Bacteria capable of converting organic waste into electricity, fertilizer, and clean water have been demonstrated at festivals and field trials across three continents. A Frontiers in Science review examines what it will take to move from pilots to global infrastructure.

A computer model built from 12 public databases and trained on millions of data points can identify extinction risks for over 10,000 freshwater fish species worldwide - and found that most could still be protected before reaching endangered status.

A team from the University of Illinois and University of Chicago developed a method using the undetected gravitational-wave background from merging black holes to constrain the Hubble constant, producing results consistent with the Hubble tension region when combined with individual event measurements.

With just 82 pediatricians per 100,000 children nationally compared with 348 adult physicians per 100,000 adults, UC San Francisco launched Peds-START in January 2025 to recruit and train medical students committed to pediatric careers through structured mentorship and a guaranteed residency pathway.

A Technical University of Berlin study using virtual reality concert halls found that wall color significantly affects perceived sound timbre, with more saturated cool colors producing a colder-sounding impression even when the acoustic conditions are identical.
