Phys.org / Scientists explain how nucleolus sub-compartments drive ribosome assembly
The nucleolus is a liquid-like cellular organelle where protein factories called ribosomes are assembled. Researchers knew of three distinct compartments within the nucleolus, but how these compartments function to drive ...
Phys.org / Ticks that survive pesticides can withstand colder winters
Ticks that survive less-than-lethal doses of pesticide are able to withstand dangerous cold, which could help them spread tick-borne diseases farther north, a UC study has found. Biologists with the University of Cincinnati ...
Medical Xpress / Brain circuits may help explain cognitive symptoms in progressive supranuclear palsy
Researchers at Japan's National Institutes for Quantum Science and Technology (QST) have found that tau buildup in progressive supranuclear palsy (PSP) may affect brain networks involved in thinking and behavior. The findings ...
Phys.org / Magnetic fingerprint of a cosmic explosion detected for the first time
Astronomers have made a series of landmark observations of one of the universe's most violent events. Using the U.S. National Science Foundation Very Large Array (NSF VLA) radio telescope, which is operated by the U.S. National ...
Phys.org / The spin of Pluto's moon, Charon, may be slowing down
Evidence of the slowing of Charon's spin period (despinning) is recorded in tectonic features on the surface of Pluto's icy moon, according to a modeling study published in Nature Communications. The findings offer insights ...
Phys.org / Medaka males can mate 27 times daily, but sperm performance drops fast
Oryzias latipes, commonly known as medaka, is a small fish measuring about 2–3 cm (0.8–1.2 inches) in length that exhibits highly active spawning behavior during the breeding season. Previous research by an Osaka Metropolitan ...
Phys.org / Hidden muscle machinery reveals 50 new gene subfamilies across vertebrates
Within every muscle of every living species with a backbone, a protein called myosin tugs on a partner protein to generate a muscle contraction. This function, discovered in mammals a century ago, has been presumed by scientists ...
Medical Xpress / Semaglutide and other GLP-1 drugs not linked to risk of degenerative eye disease in adults with type 2 diabetes
An estimated 27% of U.S. adults with diabetes are using glucagon-like peptide-1 receptor agonists (GLP-1 RAs)—a type of medication that mimics the GLP-1 hormone—to lower blood sugar and support weight loss. Some research ...
Medical Xpress / Researchers investigate potential connections between menopausal hormone therapy and ocular health
Faculty members at the University of Colorado Anschutz School of Medicine are working together across academic departments to learn more about how menopausal hormone therapy, sometimes referred to as hormone replacement therapy, ...
Phys.org / Honey bees' sense of smell changes from larval to adult life stages, study finds
Honey bee larvae lack the sophisticated olfactory capabilities of adult honey bees, a new study finds. Scientists point to this temporary loss of function as a side effect of the nurse bees' heroic level of brood care, calling ...
Phys.org / Bone 'fingerprints' unlock hidden stories of underwater caves
Bones preserved in underwater caves offer a rare and powerful window into the past—but until now, researchers have had limited tools to understand how the remains of extinct megafauna and other animals came to rest in their ...
Phys.org / 'Silly sprinklers' put in reverse to further unravel decades-old physics puzzle
Each summer, lawns are marked by a familiar addition: "silly sprinklers," whose loops and spirals spew water in creative ways. While seemingly frivolous in their construction, a team of mathematicians has used their design ...
