Phys.org / Light lets microswimmers switch between bacteria-like and algae-like propulsion
Physicists at Leipzig University and Charles University in Prague have developed a method for changing the swimming style of tiny artificial microswimmers in real time. They can make a single microscopic particle switch at ...
Medical Xpress / Scientists pinpoint two brain regions that battle it out when deciding whether to take a risk
Every day, your brain runs the same calculation: Take a risk or play it safe? Your gas tank might be low, but there's just enough to make it to work on time. Do you stop and risk being late? If you're out of money at the ...
Phys.org / More than puppy love: How therapy dogs bring students together
Students may come for the dog, but new research from UBC Okanagan published in the Journal of College Student Mental Health suggests that's not always what they leave with. In a study of 676 students—most in their first year—researchers ...
Medical Xpress / Bacteria in the airway may shape air pollution health risk
Air pollution is linked to different risks of bacterial pneumonia, sepsis and meningitis, depending on the bacterial subtype a person carries, new research suggests.
Phys.org / Bubbles the food-stealing dolphin finds shortcut to easy meal
A dolphin that harasses fish until they regurgitate their food—then swoops in to steal it—has astonished University of the Sunshine Coast researchers who have documented this novel feeding strategy.
Tech Xplore / Flexible flight corridors let drones navigate cluttered spaces faster and more safely
Researchers at Durham University have developed a new drone navigation system that enables autonomous aircraft to fly faster, more smoothly and more safely through crowded and obstacle-filled environments. This leads to new ...
Phys.org / Antibody cocktails could steer viruses into evolutionary dead ends
When a virus mutates, the world usually finds out the hard way. Variants of influenza and SARS-CoV-2 can slip past vaccines and antibody drugs before scientists fully understand what has changed. A new study from Harvard's ...
Medical Xpress / Patient-specific AI technique could make minimally invasive surgeries safer and more precise
Researchers have created a new technique that accurately and rapidly matches X-rays captured during surgery with a patient's preoperative 3D medical scan. This method could make it easier for clinicians to precisely guide ...
Phys.org / Disordered atoms steer shared light pulses by matching motion and timing
A research team at the Institute of Applied Physics at TU Darmstadt has shown for the first time that atoms that are completely disordered and in constant motion can nevertheless emit jointly directed light preferentially ...
Medical Xpress / Rare cortical neurons can synchronize brain activity and promote sleep in mice
What makes the brain fall asleep? For nearly a century, scientists have looked to structures deep within the brain for the answer. In the traditional view, these regions control when we sleep and wake, while the cerebral ...
Tech Xplore / NYT alleges Microsoft, OpenAI knew using news content was theft
OpenAI committed "an astonishing theft of unprecedented proportions" when it used millions of news articles to train its artificial intelligence models, The New York Times alleged in a court document unsealed Thursday.
Phys.org / Mitotic chromosomes may assemble from pre-existing chromatin 'building blocks' during cell division
Inside each human cell, about 2 meters (6.6 feet) of genomic DNA must be accurately copied and equally transmitted to two daughter cells during cell division. To achieve this, the copied DNA is condensed into thick, short ...
