Tech Xplore / Innovative welding filler metals extend the service life of offshore wind turbine towers
Offshore wind turbines consist of numerous welded components and are exposed to extreme loads from wind and waves at sea. These lead to cyclic stresses that particularly affect the weld seams. Until now, these have been considered ...
Medical Xpress / Exoskeletons for people with cerebral palsy are now a reality—but there's still much to figure out
Cerebral palsy is the most common disability that starts in childhood, affecting about 50 million people worldwide.
Phys.org / Enzymes that assemble into droplets can speed up cellular reactions, biologists find
Within the past decade, biologists have discovered that one strategy cells use to keep their contents organized is a phenomenon known as phase separation. Similar to the way oil forms droplets that float in a vinegar solution, ...
Medical Xpress / Conductive plastic mimics heart cell ion signaling for first time
For the first time, scientists have succeeded in artificially mimicking the ion signaling of heart muscle cells. To succeed, researchers at LiU have used organic electronics based on conductive plastics. The findings, published ...
Phys.org / Climate change and wine grapes: Go, stay or change?
On a hot afternoon in California wine country, the sun can do more than warm a vineyard. It can scorch it. When temperatures climb above 100°F, grape clusters can heat to nearly 140° in direct sunlight. The berries shrivel. ...
Phys.org / Predicting physics without parameter tuning: A faster computational approach
Numerical simulations in physics often require estimating a multitude of parameters, making the process computationally expensive and complex. Researchers at University of Tsukuba have introduced a new method called the multiparameter ...
Tech Xplore / Making LLMs faster and more efficient across multiple languages
Large language models (LLMs), which are the artificial intelligence (AI) systems behind modern chatbots, translation tools, and virtual assistants, have become revolutionary tools worldwide. Companies, governments, schools, ...
Phys.org / Eroding a virtue: AI trains people to expect instant answers, and that's bad news for patience
When I was growing up, teachers would assign research papers that required going to the library, or later, searching for relevant material on the internet. If the paper was going to turn out well, we students needed to patiently ...
Medical Xpress / A 3D printed stent, shaped like a lily, could speed recovery after weight-loss surgery
Each year, about 250,000 Americans undergo sleeve gastrectomy, one of the most common weight-loss operations in the United States. For most patients, recovery is uneventful. But for a small share—between 1% and 3% in routine ...
Medical Xpress / Repeated teen cannabis use may disrupt dopamine-related brain development, MRI data suggest
A new study from Bradley Hospital researchers shows that cannabis use during adolescence is associated with differences in brain regions involved in motivation and reward, which support healthy development.
Phys.org / Nine decades of changing insect diversity in Switzerland expose a striking divide
Thanks to a historical data archive, Swiss researchers are able to draw conclusions about the changes in the diversity of two insect groups over the past 90 years. The study, led by Agroscope, identified a significant decline ...
Phys.org / Why do male chimpanzees throw rocks at the same trees for more than a decade?
Walking through the savanna-woodland landscape of Boé National Park, Guinea-Bissau, you might encounter a tree covered in gnarled scars, with an accumulation of rocks surrounding its base.
