Phys.org / Waste management in spider mites reveals evolutionary insights into arthropod social behavior
Researchers at University of Tsukuba have discovered the adaptive significance of the remarkable waste-management behavior in the social spider mite Stigmaeopsis longus, a tiny herbivorous arthropod that lives in cooperative ...
Tech Xplore / What's the best way to expand the US electricity grid? Study illuminates choices about reliability, cost and emissions
Growing energy demand means the U.S. will almost certainly have to expand its electricity grid in coming years. What's the best way to do this? A new study by MIT researchers examines legislation introduced in Congress and ...
Phys.org / Bat study shows motherhood comes with a cost, but not for all
Is it better to have children early or later in life, and does parenthood accelerate aging? Researchers at University College Dublin and the University of Bristol have tackled these questions by studying an exceptional population ...
Phys.org / Complex life developed nearly 1 billion years earlier than previously thought, study reveals
Complex life began to develop earlier, and over a longer span of time, than previously believed, a new study has revealed. The research sheds new light on the conditions needed for early organisms to evolve and challenges ...
Phys.org / Lemon shark caught preying on invasive freshwater fish in Fernando de Noronha, Brazil
Researchers recorded lemon sharks (Negaprion brevirostris) preying on an invasive species, the jaguar cichlid (Parachromis managuensis), for the first time. This observation was made in Sueste Bay in March 2024. Sueste Bay ...
Medical Xpress / Switching risk and protective alleles improves Alzheimer's-disease-like signatures and disruptions in mice
Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the progressive degradation of brain cells, as well as an associated decline in memory and other mental functions. Earlier research found that different ...
Medical Xpress / Rapid, low-cost tests can help prevent child deaths from contaminated medicinal syrups
Researchers at the University of Oxford and their collaborators have demonstrated that simple, rapid, and inexpensive tests can detect deadly contaminants in medicinal syrups—contaminants that have tragically led to the ...
Medical Xpress / Key kidney sensor that helps control fluid balance identified
A new study has identified a critical "pressure sensor" inside the kidney that helps the body control blood pressure and fluid levels. The finding helps explain how the kidneys sense changes in blood volume—something scientists ...
Phys.org / The bacteria that won't wake up: NASA discovers new bacteria 'playing dead'
New research conducted on a NASA-discovered bacterium shows the microbe is capable of entering an extreme dormant state, essentially "playing dead" to survive in some of the cleanest environments on Earth.
Phys.org / Ancient quakes along 150-mile fault system in Nepal revealed
A common misconception about research is that it takes place in climate-controlled labs with microscopes, beakers, and Bunsen burners. While that is true for many fields, obtaining geoscience data can demand fieldwork in ...
Tech Xplore / Overparameterized neural networks: Feature learning precedes overfitting, research finds
Modern neural networks, with billions of parameters, are so overparameterized that they can "overfit" even random, structureless data. Yet when trained on datasets with structure, they learn the underlying features.
Phys.org / Why the Amazon's ability to make its own rain matters more than ever
Dr. Magali Nehemy stood on the banks of the Tapajós River in the Amazon rainforest when the community's chief—a man in his seventies who had lived there his whole life—looked out over the bare shoreline and shook his ...
