Phys.org / Under snowpacks, microbes drive a winter-to-spring nitrogen pulse, study finds
When snow blankets the landscape, it may seem like life slows down. But beneath the surface, an entire world of activity is unfolding.
Phys.org / Modeling finds old-growth wildfire risk highest where low-severity fires once burned
A new analysis shows that the Pacific Northwest's mature and old-growth forests are most at risk of severe wildfire in areas that historically burned frequently at lower severity. The study by scientists at Oregon State University ...
Tech Xplore / A programmable, Lego-like material for robots emulates life's flexibility
Mechanical engineers at Duke University have demonstrated a proof-of-concept method for programming mechanical properties into solid Lego-like building blocks. By controlling the solidity of hundreds of individual cells in ...
Phys.org / Long-period Jupiter-like exoplanet discovered with TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new extrasolar planet transiting a distant star. The newfound alien world, designated TOI-6692 b, is the size ...
Phys.org / New framework maps seven pillars for judging research trustworthiness
A new paper proposes a systems-level framework for evaluating the trustworthiness of research findings across methods and approaches. The paper, titled "A Framework for Assessing the Trustworthiness of Research Findings," ...
Medical Xpress / Pancreatic tumors eliminated in mice without resistance developing
Current drugs for pancreatic cancer lose effectiveness within months because the tumor becomes resistant. Now, a group from Spain's National Cancer Research Centre (CNIO) has been able to avoid the development of resistance ...
Medical Xpress / Saline nasal spray alone resolves sleep-disordered breathing in nearly one-third of children, study finds
Investigators based at Monash Children's Hospital and Royal Children's Hospital Melbourne report that a once-daily intranasal saline spray resolved obstructive sleep-disordered breathing symptoms in nearly one-third of children ...
Phys.org / Ozone-depleting CFCs detected in historical measurements—20 years earlier than previously known
An international research team led by the University of Bremen has detected chlorofluorocarbons (CFCs) in Earth's atmosphere for the first time in historical measurements from 1951—20 years earlier than previously known. ...
Medical Xpress / How sleep loss can damage your brain's wiring
Sleep loss damages the fatty insulation protecting the nerve cells in our brain, according to a paper published in the journal Proceedings of the National Academy of Sciences. The research also explains why we often feel ...
Phys.org / Cosmic radiation brought to light: Researchers measure ionization in dark cloud for the first time
Where starlight doesn't reach, new things are born: For the first time, an international research team has directly measured the effect of cosmic radiation in a cold molecular cloud. The observation shows how charged high-energy ...
Phys.org / Agave or bust! Mexican long-nosed bats head farther north in search of sweet nectar
Mexican long-nosed bats have a taste for agave, their tongues designed to lap up the famous desert plant's nectar during nightly flights. It's not just a means of satisfying taste buds. It's a matter of fueling up for an ...
Phys.org / AI systems could identify math anxiety from student inputs and change feedback
Math anxiety is a significant challenge for students worldwide. While personalized support is widely recognized as the most effective way to address it, many teachers struggle to deliver this level of support at scale within ...
