Phys.org / ISS study identifies thresholds for muscle atrophy and fiber changes in reduced gravity
It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in near-zero gravity (microgravity) environments. However, the gravity threshold needed to maintain sufficient ...
Phys.org / Fossil X-ray reveals new species of baby dino named for iconic Korean cartoon
Cute, green, and sporting two sprigs of hair on his head, a mischievous baby dinosaur named Dooly is one of the most beloved cartoon characters in South Korea. So, when researchers from The University of Texas at Austin and ...
Phys.org / Solar energy transforms polystyrene waste into valuable chemicals using sulfur
Turning waste into wealth may no longer be just a marketing slogan, as a team of researchers in China has found an eco-friendly way to do exactly that. The abundant sunlight our planet receives was put to use for transforming ...
Phys.org / Two new fungi species uncovered in Australian herbarium using DNA sequencing
Scientists at Royal Botanic Gardens Victoria, Australia have described two new species of fungi, Peziza austroechinospora and Peziza meridionalis with the assistance of DNA sequencing, highlighting how modern science is revealing ...
Phys.org / Sea creatures reveal the physics behind animal body shape diversity
Animals come in an extraordinary range of body shapes. A starfish looks nothing like an earthworm, a mouse, or a human. Yet even closely related species can appear radically different: corals, jellyfish, and sea anemones ...
Phys.org / Scientists create wheat-only gel from bran fiber and gluten protein
Scientists in Sweden have for the first time created a fully wheat-based gel made entirely from wheat bran fiber and wheat gluten protein—an advance that could turn one of the grain industry's least valued by-products into ...
Phys.org / Experiment challenges hypothesis of cell-like membranes on Titan
New experimental results have cast doubt on earlier proposals suggesting that spherical, cell-like membranes could form in the methane lakes of Saturn's largest moon. Through results published in Science Advances, Tuan Vu ...
Phys.org / How clonal raider ants update their friend-or-foe recognition
For ants, the ability to instantly distinguish nestmates from outsiders who might hijack the colony is crucial. Now, a new study shows that the system that ants use to determine who belongs in the colony is far more flexible ...
Phys.org / New DNA evidence reveals the complex origin of Palau's first settlers
A new genetic study published in the journal Cell is filling in some important details about the earliest inhabitants of Palau, an island nation in the western Pacific Ocean consisting of approximately 340 islands.
Phys.org / Low-cost test dissolves threat of fake drugs
Fake news can be tricky to spot, but spotting fake drugs just got a little easier. Researchers have devised a low-cost way to help distinguish legitimate medications from counterfeit ones.
Phys.org / Cells in the mosquito's gut drive its appetite, research shows
Researchers have known for decades that female mosquitoes—the ones responsible for the itchy and irritating bites that can also transmit disease—lose their desire to bite humans for several days after feeding, as they ...
Medical Xpress / Largest study of its kind tests hydration strategy for kidney stones
Kidney stones can cause some of the most intense pain people ever experience, affecting daily life and leading many to hospital emergency visits. It affects one in 11 people in the U.S., and almost half will experience a ...
