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 / A tiny protein tweak, finally traceable: How light-based tagging targets pyroglutamate
Amino acids are like Lego blocks—they can be linked together to form complex structures called proteins. Unlike Legos, however, there are only 20 different types of amino acids available to build a protein. Proteins depend ...
Phys.org / The 'silent takeover': Invasive bees are reshaping Chile's unique pollination networks
Biological invasions are a major driver of biodiversity loss and invasive pollinators can reshape native plant-pollinator networks. A new study published in the journal NeoBiota reveals that invasive pollinators are fundamentally ...
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 ...
Medical Xpress / The epigenetics of trauma: 86 miRNAs linked to PTSD symptom severity and social adversity
Adverse childhood experiences and traumatic events experienced or witnessed at any point during one's lifetime can sometimes prompt the emergence of some mental health disorders, such as post-traumatic stress disorder (PTSD) ...
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, ...
Medical Xpress / Walking pace may outperform blood pressure and cholesterol in predicting mortality risk, study suggests
A new analysis of more than 400,000 UK adults has found that easy-to-collect measures of physical health, particularly how fast someone walks, can significantly improve predictions of mortality risk. This finding was especially ...
Phys.org / Unlocking longevity insights from ancient bristlecone pine
What can the world's longest living individual teach us about longevity? A team of scientists coordinated by the University of California, Davis, sequenced the Great Basin bristlecone pine genome, which could help unlock ...
Tech Xplore / Who will govern the AI of the future? A study analyzes who will set the rules
Amid the rapid expansion of artificial intelligence and the debate on how it should be regulated, research by the Universitat Oberta de Catalunya (UOC) examines a key question: who sets the rules and through what infrastructure. ...
Tech Xplore / Highly performing AI agents can still fail to spot deception, study finds
Large language models (LLMs), artificial intelligence systems that can process and generate texts in different languages, are now used daily by many people worldwide. As these models can rapidly source information and create ...
Medical Xpress / Ejaculating more often may boost sperm motility and reduce DNA damage
When it comes to reproduction, female biology is often described in terms of a ticking clock. Women are born with most of their lifetime supply of eggs, meaning that a woman's age is usually the same as the age of her eggs. ...
Phys.org / New NMR method allows the observation of chalcogen bonds
Toward the right side of the periodic table below oxygen, are the chalcogens, or "ore-forming" elements. The chalcogens that occur naturally, including sulfur, selenium and tellurium, are all somehow involved in biological ...
