Phys.org / Kenya's big cats under pressure: Cattle are pushing lions away
In the Kenyan savanna, lions and livestock essentially live in shifts: Cattle graze during the day and are enclosed at night when lions are active.
Phys.org / Compact electron accelerator offers new approach for treating PFAS-contaminated water
So-called forever chemicals or PFAS compounds are a growing environmental problem. An innovative approach to treating PFAS‐contaminated water and soil now comes from accelerator physics: high‐energy electrons can break ...
Phys.org / Ultrafast light switches use atomically thin semiconductors for rapid optical control
A nanostructure made of silver and an atomically thin semiconductor layer can be turned into an ultrafast switching mirror device that may function as an optical transistor—with a switching speed around 10,000 times faster ...
Phys.org / Unified framework sorts spacetime fluctuations for quantum-gravity experiments
A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear in many attempts to ...
Phys.org / New method creates acinar cells involved in formation of pancreatic cancer
Organoids are three-dimensional miniature models of organs, grown in a dish. They have become a valuable tool for studying human development, organ regeneration, function, and disease progression. Organoids derived from patient ...
Phys.org / Bionic LiDAR system achieves beyond-retinal resolution through adaptive focusing
In a recent study, researchers from China have developed a chip-scale LiDAR system that mimics the human eye's foveation by dynamically concentrating high-resolution sensing on regions of interest (ROIs) while maintaining ...
Phys.org / Iron Age dental plaque reveals Scythians consumed milk from horses and ruminants
Researchers have deciphered the diet of an important nomadic people in Eastern European history. By analyzing dental calculus, they have provided the first direct evidence that the diet of the Scythians included milk from ...
Phys.org / A wild potato that changed the story of agriculture in the American Southwest
Starchy residue preserved in ancient stone tools may rewrite the story of crop domestication in the American Southwest, according to research led by the University of Utah.
Phys.org / Largest canine gut microbiome catalog reveals hundreds of new bacterial strains
Researchers at the Waltham Petcare Science Institute in the UK recently revealed a complete taxonomic and functional catalog of the canine gut microbiome after analyzing samples from 107 healthy dogs across the U.S. and Europe. ...
Phys.org / How European city life is continually rewriting insect DNA
Cities are known to shape the evolution of wildlife within them, but according to a study of European cities published in the journal Proceedings of the Royal Society B: Biological Sciences, this is not a one-off event. Rather ...
Phys.org / Metal clumps in a quantum state: Physicists place thousands of sodium atoms in a 'Schrödinger's cat state'
Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, physicists from the University ...
Phys.org / Massive black hole mystery unlocked by researchers
It's one of astronomy's great mysteries: how did black holes get so big, so massive, so quickly. An answer to this cosmic conundrum has now been provided by researchers at Ireland's Maynooth University (MU) and reported today ...
