Phys.org / Preparing for the next pandemic: Scientists discover a new class of influenza antivirals
Researchers from Leiden University, University of York, University of Barcelona/IQTCUB/ICREA and The Francis Crick Institute report a new class of experimental compounds that powerfully block influenza viruses. The findings ...
Phys.org / Snow flies produce bursts of heat and proteins to avoid freezing, new study finds
In a new study, Northwestern University scientists explored how snow flies—small, wingless insects that crawl across snow to find mates and lay eggs—survive in freezing cold temperatures. They discovered this snow-dwelling ...
Phys.org / The truth of timekeeping lies within: Key developments in understanding circadian rhythms
Almost all living things have an internal 24-hour clock that remains accurate regardless of temperature or other environmental changes. This clock is a highly sophisticated yet simple timekeeping mechanism that is critically ...
Medical Xpress / Gut-to-brain pathway explains how the immune system triggers loss of appetite during parasitic infection
Anyone who has weathered a bad stomach bug knows the feeling: a loss of appetite that sets in and lingers, even after the initial illness. For the millions of people around the world who are chronically infected with parasitic ...
Tech Xplore / 'Neuron-freezing' technique can stop LLMs from giving users unsafe responses
Researchers have identified key components in large language models (LLMs) that play a critical role in ensuring these AI systems provide safe responses to user queries. The researchers used these insights to develop and ...
Phys.org / How our reactions shape what is perceived as ethical on social media
Social media have become an integral part of everyday life for most people. Many of us follow companies on social media and react to images and campaigns that resonate with us.
Medical Xpress / Study finds wearable data may help predict patient engagement in remote COPD rehabilitation
Sleep data captured with a wearable device could help clinicians better tailor care by identifying patients with chronic obstructive pulmonary disease (COPD) who may need additional support to participate in pulmonary rehabilitation, ...
Medical Xpress / Ultra-processed foods linked to reduced fertility and embryonic development
Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth in early embryos, and smaller yolk sacs, which are essential for early embryonic development, according ...
Medical Xpress / Short-lived fish offer new insights into the aging immune system
Our immune system protects the body from infections and harmful changes throughout our lives. However, it loses its effectiveness with age, resulting in an increased risk of disease. But what happens when the immune system ...
Medical Xpress / Well-fed penguins live longer but age faster—much like modern humans
In public discourse, the increasing lifespan in Western countries is often linked to longer life in good health. However, studying human aging in modern societies is complex because outcomes are shaped by numerous social, ...
Tech Xplore / Molecular interface tuning lifts tandem solar cell efficiency to 25.1%
Researchers at UNIST have unveiled a novel interface engineering technique that significantly improves both the performance and durability of perovskite/organic tandem solar cells (POTSCs). Published in Energy & Environmental ...
Phys.org / Study reshapes understanding of interaction between organelles in animal cells
Findings from a new University of Cincinnati study have reshaped the fundamental understanding of how a certain cell organelle prepares its environment for cellular digestion. The study, led by UC's Jiajie Diao, Ph.D. and ...
