Phys.org / Faster tests reveal six fluoropolymer microplastics, including four rarely tracked types
Scientists around the world have been searching food, water and other environmental media for microplastics and for per- and polyfluoroalkyl substances (PFAS). But microfluoroplastics (MFPs), the intersection between these ...
Medical Xpress / Bioresorbable implant electrically stimulates organs, nerves and muscles then vanishes after treatment
To treat or manage various heart, gastrointestinal and neurological conditions, including arrhythmias, heart block, gastroparesis, epilepsy and some nerve injuries, doctors rely on a technique known as electrical stimulation. ...
Phys.org / Why some wolves react more strongly to trespassers: Breeders may hold key to scent-based barriers
Wolves use their urine to communicate with each other. A recent study looked at the reactions of a pack to the marking of an intruder. This is a first step toward understanding what attracts or repels canids.
Medical Xpress / New mechanism behind breast cancer metastasis uncovered
Researchers at Umeå University show that the protein METTL3 helps breast cancer cells spread. By regulating the release of molecules, METTL3 makes it easier for tumors to invade surrounding tissue and form metastases. The ...
Tech Xplore / Dog-bone design helps 2D nanoribbon transistors stay fast and efficient as widths shrink
Transistors, small semiconductor-based switches that control the flow of electricity, are central components of all electronic devices, from computers to smartphones, wearables, sensors and smart appliances. Over the past ...
Phys.org / New star activity catalog could sharpen hunt for habitable worlds
Searching for habitable worlds beyond our solar system involves more than having a planet orbit within its star's habitable zone, the region where temperatures could be just right for liquid water to exist on the surface. ...
Tech Xplore / New smart bicycle can tell when riders mean to turn—and when they may be falling
Two-wheeled vehicles with conventional stability-control systems must lean to change direction, making it difficult for rider-assistance systems to determine whether a rider is intentionally cornering or experiencing instability ...
Science X / Kids shrug off sunk-cost bias until about age 6, behavioral experiments reveal
Ever wonder why adults cling to things in which they've invested time or effort? In behavioral experiments, people often predict that they would stick with an option just because it was harder to get. Psychologists call this ...
Phys.org / The invasive fern that science misidentified for decades
Salvinia molesta can double its biomass in 36 hours. It spreads across ponds, lakes and slow-moving waterways in a smothering green mat, blocking sunlight, consuming oxygen and collapsing the ecosystems beneath it. Now present ...
Phys.org / How extreme weather impacts white stork survival in Bulgaria
A comprehensive 15-year study published in Biodiversity Data Journal details the growing threat of extreme weather to white storks (Ciconia ciconia) in Bulgaria. The research, which is part of the topical collection "Restoration ...
Phys.org / A new CRASH clock measures the chance of satellite collisions, and it's ticking down fast
Imagine a piece of space debris the size of a hockey puck slams into a Starlink satellite at about 10 kilometers per second. The kinetic energy is equivalent to 2 kilograms of TNT, or a fully loaded semitruck traveling at ...
Tech Xplore / LiDAR approach could change factory inspections for tiny hard-to-reach parts
Researchers have developed a new LiDAR approach that makes it possible to image small objects with much greater precision and accuracy than conventional LiDAR. The method could be useful for acquiring noncontact measurements ...
