Tech Xplore / Breaking fuel cell barriers: New platinum catalyst brings high-efficiency hydrogen vehicles closer to commercialization
A research team has developed a next-generation platinum-based catalyst that improves both activity and durability in hydrogen fuel cells. The study is published in Advanced Materials. The team was led by Professor Sang Uck ...
Phys.org / Domino polymerization provides a new route to versatile, degradable plastics
Plastic, once ingenious for its durability and versatility, has become a global environmental issue that is affecting every aspect of life. This, in turn, is fueling the development of degradable polymers as alternative solutions. ...
Phys.org / Nanotube injector transfers cytoplasmic contents and organelles between living cells safely
Cells are not isolated units; they continuously exchange proteins, genetic material, and even entire organelles with their neighbors. Intercellular transfer influences how tissues develop, respond to stress, and repair damage. ...
Medical Xpress / Overnight machine perfusion lets liver transplants safely shift to daytime, study shows
It is safe for patients to receive a donor liver that has been intentionally preserved overnight using machine perfusion to enable a daytime transplant. This is shown by a study performed at the University Medical Center ...
Phys.org / Bumblebees can perceive rhythm, despite their brains being the size of a sesame seed
Humans are creatures of rhythms. As far as we know, humans have always sung and always danced. We can recognize a song by its rhythm alone, regardless of whether it is played fast or slow.
Medical Xpress / Children living near the Salton Sea in Southern California show slower lung function growth
Children who live within 11 kilometers of the Salton Sea, a drying body of water with a high concentration of salts and contaminants in Imperial Valley, California, have slower lung function growth between ages 10 and 12 ...
Medical Xpress / Research moves closer to 'smart' sensors in knee replacements
If you have a knee replacement, imagine pointing your phone at your knee and pulling up an app that tells you how much stress the artificial joint is experiencing. Knowing the activities that cause the biggest problems—which ...
Medical Xpress / How an Alzheimer's risk gene disrupts brain circuits long before memory loss
For the millions of people who carry the gene APOE4, the strongest known genetic risk factor for Alzheimer's disease, their brain activity may begin changing long before any memory problems appear. Now, researchers at Gladstone ...
Phys.org / Bacterial enzyme uses a donut-shaped ring to shred tough collagen, study reveals
Collagen is an important protein that helps build the tissues of humans and animals. It is very strong because it is made of three protein strands twisted tightly together like a rope. Because of this sturdy structure, ordinary ...
Tech Xplore / Living brain cells enable machine learning computations
A research team at Tohoku University and Future University Hakodate has demonstrated that living biological neurons can be trained to perform a supervised temporal pattern learning task previously carried out by artificial ...
Medical Xpress / Childhood cancer is a substantial contributor to global childhood mortality and global cancer burden
Childhood cancer is the eighth-leading cause of childhood death globally and causes more deaths than measles, tuberculosis and HIV/AIDS, with outcomes largely determined by resource availability, according to the latest findings ...
Medical Xpress / Spinal cord stimulator stays rigid for surgery, then softens inside the body
What if chronic diseases, which are difficult to treat with medicine alone, could be managed with electricity? As "neuromodulation"—a technology that restores bodily balance by sending signals directly to nerves—gains attention, ...
