Phys.org / Carbon-capture technology could trigger the deforestation it was designed to prevent
A technology designed to mitigate global warming could, paradoxically, contribute to carbon emissions if hotter temperatures lead to a shift in where bioenergy crops are grown. Bioenergy with carbon capture and storage (BECCS) ...
Phys.org / Modern experiments suggest rhino teeth may have been part of Neanderthal toolkits
Neanderthals may not only have feasted on rhinoceroses, they may also have used their exceptionally hard teeth as specialized tools for a range of tasks, such as retouching the edges of stone tools.
Phys.org / Climate change: How oxygen deficiency changes metabolic processes in the ocean
The world's oceans are losing oxygen—and rapidly. The principal cause is the increasing warming of the oceans, which reduces the solubility of oxygen in water and increases respiratory activity. In addition, it strengthens ...
Medical Xpress / Today's teens are sleeping less than ever before
New research from the University of Minnesota School of Public Health shows that teenagers today are getting less sleep than any generation before them. This lack of sleep causes daily fatigue and reduced functioning, alongside ...
Medical Xpress / How screen use, not just screen time, relates to self-regulation and learning in neurodiverse children
A new Western University study that set out to assess screen time and the relationship to self-regulation in a real-world sample of children revealed those 4 to 16 years old are far exceeding recommended daily guidelines.
Phys.org / Streetlights trigger bizarre 'death spirals' in thousands of isopods, scientists find
A new study led by Ph.D. student Idan Sheizaf, under the guidance of Prof. Ariel Chipman from The Hebrew University of Jerusalem, has documented a never-before-seen behavioral phenomenon: thousands of land-dwelling isopods ...
Phys.org / Hidden changes in plant reproduction reveal new clues about evolution of self-fertilization
In flowering plants, the transition from cross-fertilization (outcrossing) to self-fertilization has evolved repeatedly across species. This shift is often accompanied by a well-known set of traits collectively called the ...
Medical Xpress / Gold-coated microneedles can detect subtleties in how liver and kidneys process drugs in real time
Scientists have taken a giant leap forward with the development of tiny microneedles designed to detect subtle but critical changes in how the liver and kidneys process therapeutic drugs. The experimental technology, under ...
Phys.org / Researcher fuels global drive for better large outdoor fire modeling
Wildfires battered Iwate Prefecture in northeastern Japan for 11 days, starting on April 22. The fires burned about 1,600 hectares and forced 3,200 residents to evacuate. With warmer climates, continued expansion of urban ...
Phys.org / What Chinook salmon eat depends on where they are in the Salish Sea, study finds
A new study by University of Victoria (UVic) and Pacific Salmon Foundation (PSF) scientists has uncovered what adult Chinook salmon in the Salish Sea are eating—and revealed diet can differ according to region. The study, ...
Tech Xplore / AI doesn't create bias, it inherits it. How do we ensure fairness when it comes to automated decisions?
If artificial intelligence (AI) systems shape decisions that affect people's lives, they should do so fairly. This should be a given considering that potential applications for AI include automated hiring systems, as well ...
Medical Xpress / Study suggests immunotherapy may strengthen treatment for aggressive prostate cancer
Researchers at Moffitt Cancer Center report encouraging early results from a phase 2 study examining whether immunotherapy can improve results when added to a radiotherapy-based treatment regimen for men with aggressive prostate ...
