High-energy-density barocaloric material could enable smaller, lighter solid-state cooling devices

A team of researchers has discovered a high-energy-density barocaloric effect in Ag₂Te₁₋ₓSₓ, a plastic superionic conductor. The material produces a reversible volumetric entropy change of 0.478 J·cm⁻³·K⁻¹ under moderate pressure, surpassing most known inorganic materials.

Airplane and hospital air is cleaner than you might think

A Northwestern University study found that airplane and hospital air mostly contain harmless microbes from human skin, with some potentially pathogenic species in extremely low abundance. The study used worn face masks as a passive tool to monitor indoor air, revealing the invisible world of microbes floating in our shared air.

Note- taking alone or combined with large language models helps students understand and remember better than large language models alone

A new study by Cambridge University Press & Assessment and Microsoft Research found that traditional learning activities like making notes remain critical for students' reading comprehension and retention. Note-taking, either alone or combined with large language models (LLMs), was more effective in helping students understand and reme...

New roadmap reveals how everyday chemicals and microbes interact to fuel antimicrobial resistance

A new perspective outlines an urgent scientific roadmap for understanding chemical-microbe interactions and their role in accelerating antimicrobial resistance. Emerging evidence highlights unexpected combined effects of pollutants at low levels, which can promote resistance even when each chemical is present alone.

Breakthrough pediatric kidney therapy emerges from U. Iowa research

Researchers at the University of Iowa Health Care have developed a new class of medication, pegcetacoplan, which directly targets the root cause of C3 glomerulopathy, a rare and severe kidney disease. The treatment has shown significant results, with up to 67% of children achieving complete remission and stabilization of kidney function.

Research reveals how disordered protein regions contribute to cancer-causing condensates

Researchers developed a machine learning model that predicts which intrinsically disordered protein regions form condensates in cells, finding they are linked to RNA biology and occur in only about 12% of human proteins. The model, IDR-Puncta ML, provides a valuable resource for studying condensate formation in cancer and RNA biology.

Valve trials validate better ways of fixing a malfunctioning heart

Recent trials have shown that catheter-based procedures can match the long-term results of open-heart surgery in relatively healthy patients with valvular disease. These procedures offer life-saving options to people too frail for open-heart surgery and are expected to bring more upcoming trials to New Brunswick.

UT Health Science Center researchers use ‘brain-on-a-chip’ to revolutionize fight against deadly encephalitis viruses

Researchers at the University of Tennessee Health Science Center are using a human brain-on-a-chip system to study lethal encephalitis viruses and develop treatments. The chip replicates the function of the human brain, allowing scientists to test antiviral drugs in a more accurate and human-like environment.

New design tackles heat challenges in high-power fiber lasers

Researchers at Fraunhofer IOF have developed a single-material cladding light stripper with self-adapting behavior, overcoming nonlinear effects and heat buildup in thulium fiber lasers. The design enables over 20 W of stripped signal light at 2 µm and up to 675 W at 793 nm, setting a new record for single-material CLS designs.

Long-term benefits of daily multivitamin use may vary by diet quality and baseline blood pressure

A daily multivitamin may be beneficial for reducing the risk of hypertension in people with poorer nutritional intake. Multivitamins lowered risk of hypertension in participants with comparatively lower diet quality, as measured by Alternative Healthy Eating Index (AHEI) and Alternate Mediterranean Diet (aMED) scores.

Diabetes drugs may help older adults slow frailty

A new study suggests that SGLT-2 inhibitors and GLP-1 receptor agonists may help older adults with type 2 diabetes maintain strength, mobility, and independence. The findings indicate a potential direct benefit of these medications on frailty itself, which could change how clinicians think about medication choices for aging patients.
