Phys.org / Silver nanocatalysts switch reaction sites between power generation and hydrogen production
For the first time, researchers have discovered that the same silver (Ag) nanocatalyst operates at different reaction sites depending on whether a solid oxide cell is generating electricity or producing hydrogen. This finding ...
Phys.org / Songbirds may have developed sharper senses to de-husk seeds
Songbirds, birds belonging to the Passeriformes order, are best known for their ability to produce complex musical sounds. Yet some songbird species also have another remarkable skill: They can easily remove the tough layer ...
Phys.org / Ant teams beat gravity-based puzzle solvers
Ants live in highly organized colonies and cooperate daily to tackle a wide range of problems. Their striking group behaviors have fascinated biologists for centuries and even inspired the development of various artificial ...
Medical Xpress / Household hums below hearing range damage mouse kidneys in five-day experiment
Previous studies have hinted that people surrounded by more environmental noise—low, deep rumblings from air-conditioning units, elevator motors, distant traffic and ventilation ducts—tend to have worse kidney function. But ...
Phys.org / One million years without sex fails to erase stick insects' unused biological system
Scientists have made a surprising finding about how an asexually reproducing stick insect has evolved. Research led by Dr. Darren Parker, lecturer in evolutionary biology at Bangor University, studied the genes of several ...
Phys.org / Phages unlock essential vitamin B12 by bursting open gut bacteria
All living organisms need vitamin B12 to form red blood cells and DNA, as well as to build and support brain and nerve cells. But it's hard to come by: Humans don't make it. Animals don't make it. Plants don't make it. In ...
Medical Xpress / Radiopharmaceutical may benefit patients with metastatic prostate cancer sooner
Earlier use of a targeted radionuclide therapy delays metastatic prostate cancer progression when administered as part of a trio of drugs, according to a Phase III clinical trial led by Weill Cornell Medicine, NewYork-Presbyterian, ...
Tech Xplore / A new attack slips past the latest defenses built into your computer's processor
Chipmakers and operating system developers have spent years building defenses. A new study from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) shows that a key assumption behind many of them doesn't ...
Medical Xpress / Parkinson's-linked α-synuclein blocks protein transport in neurons, disrupting cells' waste recycling
Parkinson's disease affects more than 10 million people worldwide. The disease is characterized by the buildup of abnormal clumps of the protein alpha-synuclein inside brain cells, but scientists have long struggled to understand ...
Phys.org / Runaway supermassive black hole RBH-1 offers new way to reconstruct ancient merger
Black holes are fascinating regions in space where gravity is so strong that nothing, even light, can escape them. The largest known black holes, called supermassive black holes, contain millions to billions of times the ...
Phys.org / Simulations hint at a hidden population of companionless black holes
So far, almost all stellar-mass black holes detected by astronomers have been found in binary systems. However, astronomers have long suspected that these binary black holes are the exception and that, within the Milky Way, ...
Phys.org / Venus's polygonal plains could point to a watery past
Venus may be overwhelmingly inhospitable today, but many planetary scientists believe that it wasn't always this way. Billions of years ago, some observational evidence suggested that our planetary neighbor may have looked ...
