Phys.org / Microbial ancestor of complex life was more sophisticated than previously thought, studies suggest
Our single-celled ancestor lived in a world without plants, animals or oxygen-rich oceans. Yet, this seemingly simple microorganism took the first steps toward complex life. From this ancestor emerged all multicellular (complex) ...
Medical Xpress / Deciding for others can lower confidence in one's own judgments
From the moment we wake to the time we hit the bed at night, we make numerous decisions, some big but mostly small. Although decision-making is a fundamental part of human life, researchers have found that the level of difficulty ...
Medical Xpress / Cancer has a unique nuclear metabolic fingerprint, researchers discover
More than 200 metabolic enzymes, many of which are normally tasked with producing energy in the mitochondria, are also found sitting directly on top of human DNA, according to a study published in Nature Communications. The ...
Phys.org / Toxic evolution: How wasps and frogs mimic pain molecules to deter predators
Certain species of wasps and frogs share a pain and inflammation peptide similar to one found in vertebrates to help defend against predators—a discovery that contributes to a shifting view of how evolution works, say researchers. ...
Tech Xplore / 'AI will be the end of us': Is Colm Tóibín right about the threat to creative writing?
In 1950, William Faulkner delivered a famous acceptance speech for the Nobel prize in literature in which he rallied for the "inexhaustible [human] voice" and his belief in its supremacy—not merely to endure but to prevail. ...
Phys.org / Molecular 'catapult' fires electrons at the limits of physics
Electrons can be "kicked across" solar materials at almost the fastest speed nature allows, scientists have discovered, challenging long-held theories about how solar energy systems work. The finding could help researchers ...
Medical Xpress / Enhanced brain cells clear away dementia-related proteins
The new generation of Alzheimer's disease drugs—the first proven to change the course of the disease—typically extend independent living for patients by 10 months. Called monoclonal antibodies, they reduce the accumulation ...
Phys.org / Why woodpeckers rarely get rattled: Skulls built to control rotation, not cushion blows
Woodpeckers are well known for striking tree trunks with remarkable force and precision. These birds deliver thousands of high-speed impacts per day, generating mechanical loads that would destabilize the skulls of most other ...
Medical Xpress / New study shows how sickle cell affects brain function
Sickle cell disease is often thought of solely as a blood disorder, but new research from the Wood Neuro Research Group provides measurable evidence that it can reshape how brain networks function. Previous neuroimaging studies ...
Phys.org / Scientists successfully harvest chickpeas from 'moon dirt'
As the U.S. plans to return to the moon with the upcoming Artemis II mission, a question endures: What will future lunar explorers eat? According to new research from The University of Texas at Austin, the answer might be ...
Tech Xplore / Graphene-based 'artificial skin' brings human-like touch closer to robots
Robots are becoming increasingly capable in vision and movement, yet touch remains one of their major weaknesses. Now, researchers have developed a miniature tactile sensor that could give robots something much closer to ...
Tech Xplore / Multiply and subtract your way to more lifelike VR avatars
POSTECH's (Pohang University of Science and Technology) Professor Inseok Hwang's team has developed ArithMotion, a mobile virtual reality (VR) system that enables anyone to express a wide range of avatar motions with ease. ...
