Updated guidelines from 11 medical organizations introduce the PREVENT-ASCVD risk calculator, set LDL-C goals as low as 55 mg/dL for very high-risk patients, and recommend universal one-time lipoprotein(a) screening in adults.

Immunity to both HA and NA surface proteins of H1N1 influenza halved airborne transmission between ferrets, with no evidence of immune escape mutations - suggesting future vaccines could blunt spread at the source.

Replacing ordinary water with heavy water in the electrolyte bath surrounding carbon nanotube 'twistron' yarns boosted peak electrical power 2.5-fold and energy output 1.8-fold per stretch cycle, reaching 9.5% conversion efficiency.

A batch of early-online AMS journal articles covers 21st-century Mississippi River hydrology, Southern Ocean carbon uptake, gender disparities in European flood fatalities, and climate skepticism among Western U.S. ranchers, among other findings.

A gene variant that helps yaks survive at 14,700 feet boosted myelin regeneration and reversed MS-like symptoms in mice by ramping up a vitamin A metabolite called ATDR - a molecule humans naturally produce but may not make enough of.

Researchers at the Dalian Institute of Chemical Physics achieved a methanol space-time yield of 1.2 grams per gram of catalyst per hour from CO2 hydrogenation - roughly three times the output of conventional Cu/Zn/Al catalysts - by spatially separating active sites through a strong metal-support interaction overlayer.

A JAMA Network Open study finds that older adults recovering from major elective noncardiac surgery face months of daily living impairment, with caregivers sharing the burden. The researchers call for better preoperative education, caregiver-inclusive discharge planning, and earlier follow-up.

Despite consensus endorsement of donor care units for improving organ donation outcomes, their adoption has been uneven across the U.S. A new study finds that many deceased donors after brain death face drives of more than 180 minutes to reach the nearest unit.

Researchers used machine learning interatomic potential calculations to screen dopant candidates for the recently discovered photocatalyst orthorhombic Sn3O4, then validated experimentally that aluminum doping boosts hydrogen production 16-fold under visible light.

Researchers show that the glutathione-lowering compound BSO replicates the fat-reducing effects of sulfur amino acid restriction in obese mice without the bone mineral density loss and marrow adiposity that make the dietary approach impractical. The finding separates two previously linked biological effects.

The first real-world clinical evaluation of China's YDHB-NS01 vascular robotic system for cerebral angiography showed 100% success rates in 25 robot-assisted procedures, with significantly shorter procedure times than matched manual cases and no increase in radiation dose or complications.

Researchers have mapped the temperature-sensitive period and early gene expression changes that determine sex in leopard geckos, finding that incubation at 26.5C produces 100% females while 31.5C yields 91% males - with molecular divergence beginning well before any physical differences are visible.

An international team has confirmed a new chemical reaction - trisulfide metathesis - that spontaneously makes and breaks sulfur-sulfur bonds at room temperature without reagents or external stimuli, enabling applications from targeted cancer drugs to closed-loop recyclable polymers.

A study of free-living Northern cardinals found that even mild stressors like brief captivity or simulated territorial encounters leave detectable marks on gut microbiome composition, with bacterial shifts tracking closely to changes in stress hormones and visible health indicators.

Mass General Brigham researchers built three AI models that mine electronic medical records for signs of intimate partner violence. The best-performing model, which combines diagnostic codes with free-text clinical notes, identified at-risk patients up to four years before they sought help.

Researchers at Harvard Medical School and Mass General Brigham have developed AI models that use routine electronic medical record data to identify patients at risk of intimate partner violence, achieving 88% accuracy and detecting risk more than three years before patients sought help.

A study in Nature Climate Change establishes modeling principles for post-growth climate scenarios, showing that wealthy nations could satisfy universal basic needs using less than half current global energy and materials - if production is restructured and inequality substantially reduced.

Researchers have determined the 2.4-angstrom structure of a unique light-harvesting protein from a freshwater alga, revealing how it arranges ordinary chlorophyll a into cooperative clusters that absorb far-red light - a wavelength most photosynthetic organisms cannot use.

Scientists drilled to bedrock at Austria's Weissseespitze glacier and recovered a pollution record stretching back over 2,000 years. When they returned in 2025, the ice had thinned from 9.5 to 5.5 meters. The archive is melting before it can be fully read.

By probing the spin properties of short-lived electron-hole pairs inside operating light-emitting electrochemical cells, researchers discovered that lower, more stable internal electric fields actually boost light output - a finding that could guide the design of more efficient organic LEDs.

Researchers have built a 30mm soft robot that uses magnetorheological fluid to fold and unfold under magnetic control, navigating the gastrointestinal tract to deliver drugs directly to target sites. In pig stomach tests, it reached preset lesion locations within five minutes.

Sylvester Comprehensive Cancer Center outlines its active research fronts for March 2026, including mRNA immunotherapy for colorectal cancer, real-time liquid biopsy monitoring of prostate cancer, and a landmark $100 million fundraising milestone from the Dolphins Cancer Challenge.

A Nagoya University team has achieved the first heteroepitaxial growth of gallium oxide on silicon substrates, paired with five other advances in thin-film growth that collectively address the full process stack needed to commercialize this promising power semiconductor material.

Researchers at the Netherlands Institute for Neuroscience have identified seven distinct types of hyperarousal that cut across mental health disorders, and developed a concise questionnaire to measure them - potentially reshaping how clinicians diagnose and treat conditions like insomnia and anxiety.

The first systematic study of AI-powered talking toys reveals they struggle with emotional cues, disrupt pretend play, and may foster unhealthy attachments in young children. Cambridge researchers are calling for new safety regulations and labeling standards.
