Phys.org / Why tipping fatigue is growing in Canada
Ever feel uncomfortable when a payment screen asks for a tip? We sure have. As tipping prompts become more widespread, more consumers are feeling uneasy or frustrated, but not always sure why.
Phys.org / Flatworms reveal exploding immune cells that kill surrounding tissue
Stanford scientists have discovered a new type of immune cell that kills surrounding cells via explosion—a cellular detonation so fast and complete that the cell vanishes within minutes, leaving no trace behind. This discovery ...
Science X / A calmer, happier you? One everyday escape may hold the key
A walk through a park may do more than clear your head—it could measurably improve your mental health. In one of the largest reviews of its kind, researchers analyzed nearly 4,000 studies involving more than 10 million people ...
Phys.org / Dormant black hole revives in under three years, brightening 10-fold in nearby galaxy
Astronomers monitoring a nearby active galaxy for six years have watched its supermassive black hole dramatically wake up, brightening by a factor of 10 across ultraviolet and X-ray wavelengths. The paper outlining the study ...
Phys.org / Ötzi the Iceman and his microbiome—a 5,300-year-old relationship
Researchers at Eurac Research have obtained a detailed picture of the microbial community associated with Ötzi, Europe's oldest known natural human mummy. The study provides insights into a complex microbiome, ranging from ...
Phys.org / Atomic reshuffle leads to record-breaking catalysts for hydrogen production
Researchers have discovered that atoms can be mixed, separated, and recombined within the same experiment, providing a pathway to a record-breaking catalyst for green hydrogen production. In their study, the team created ...
Medical Xpress / Major surgery may accelerate memory loss in 1 in 7 older adults
Going through surgery can take a significant toll on a patient's physical health and capabilities, especially if they are elderly. A recent study found that the effects extend far beyond mobility and pain management, as the ...
Medical Xpress / Aspirin may unmask silent bladder cancer by triggering bleeding
The presence of blood cells in urine is a sign of bladder cancer. Because aspirin blocks platelets from forming harmful blood clots, the medication can cause mild bleeding or worsen existing bleeding in the urinary tract. ...
Phys.org / Mathematician solves origami donut efficiency challenge with fewest folds
Most people wouldn't think that it would take rigorous mathematical proof to show how many folds it takes to make a donut shape out of paper. Yet, no one could quite figure it out until recently.
Medical Xpress / Novel prostate cancer treatment can reduce risk of disease progression by half, clinical trial shows
A Phase III clinical trial led by Neeraj Agarwal, MD, FASCO, senior director of clinical research at Huntsman Cancer Institute and professor of internal medicine at the University of Utah (the U), has found that a combination ...
Medical Xpress / Largest study of knee osteoarthritis tissue reveals core biological pathways underlying the disease
A major international study led by researchers at the Kennedy Institute of Rheumatology at the University of Oxford has found that osteoarthritis (OA)—the most common form of arthritis worldwide—is not a collection of separate ...
Phys.org / First deliberately injured Langobard woman in skeletal record reshapes view of male-only violence
The Langobards are frequently depicted as fierce warrior-like people, with all known archaeological evidence of violence restricted to men. However, nearly 1,400 years ago, a Langobard woman took two severe injuries to the ...
