Creating oxygen-powered chemical reactions that produce only water waste
Penn State researchers have created a synthetic mimic of a natural oxygen-activating enzyme, demonstrating a reaction that reshapes stable aromatic...
Tuft Cell-Like Tumors Reveal New Cancer Subtype With Distinct Biology, Treatment Potential
A rare epithelial cell known as the tuft cell may be far more important in cancer biology than previously thought....
Fruit flies evolved distinct genetic routes to establish heads and tails
An embryo’s first great decision is directional: which end will become the head, and which will become the tail? In...
New conservation project protects rare wildlife in orchards
Scientists from Aberystwyth University are joining a major conservation project aimed at protecting some of Britain’s rarest orchard species, combining...
Complete marmoset genome opens new avenues for Alzheimer’s and neurodegeneration research
Scientists have produced the first complete, end-to-end genome sequence of the common marmoset, creating a high-resolution genetic reference for one...
Oviduct Epithelial Folds Aid Oocyte Transport but Aren’t Essential
After ovulation, an egg begins a carefully timed journey through the oviduct, also known as the Fallopian tube, toward the...
Diverse bacterial DNA glycosylases share a conserved antiviral defense function
Bacteria are engaged in a perpetual molecular arms race with bacteriophages, the viruses that infect them. Phages inject genetic material...
Study identifies immune pathway driving systemic allergic reactions
Allergic inflammation in the skin may set the stage for life-threatening reactions elsewhere in the body through a previously unrecognized...
Scientists grow muscle protein for fake meat in lettuce and tobacco chloroplasts
Scientists have engineered tobacco and lettuce plants to produce myoglobin—the iron-rich protein responsible for much of meat’s red color and...
Pumas May Reduce Wildlife Collisions, Making Roads Safer for Drivers
Living alongside pumas may seem like a dangerous bargain, but new research suggests that the presence of these large predators...
New study investigates whether tiny dinosaurs existed, challenging evolutionary assumptions
Dinosaurs are remembered as Earth’s giants: towering sauropods that outweighed dozens of elephants, and predators such as Tyrannosaurus rex that...
Human cancer models speed research and advance precision therapies
Cancer researchers have unveiled one of the most extensive collections of patient-derived tumor models ever assembled, creating a living laboratory...
Study finds no clear IVF benefit from common embryo transfer techniques
A new Cochrane review has challenged several long-standing preparation techniques used immediately before embryo transfer in in vitro fertilization, finding...
Lithocholic acid eases fatty liver disease in mice and nonhuman primates
A bile acid long associated with liver damage may have a much narrower—and potentially useful—side to its biological identity. In...
FOXK2 discoveries broaden understanding of cancer biology and clinical care
A comprehensive review published in Genes & Diseases is drawing renewed attention to FOXK2, a transcription factor that may help...
New research reveals MYH9’s expanding role in cancer and genetic disorders
The MYH9 gene is emerging as a critical biological switch at the intersection of cancer progression and inherited disease, according...
Scientists Propose Two Possible Origins of Life
Scientists have reconstructed a possible sequence of events linking the chemistry of hydrothermal vents to the emergence of the first...
Machine-learning study finds captive black bears sleep twice as much during hibernation
American black bears may spend far more time asleep during hibernation than previously appreciated, according to a machine-learning analysis of...
Genomic surveillance maps shared Plasmodium falciparum drug-resistance variants across Ethiopia’s transmission settings
Malaria parasites in Ethiopia are carrying a more complex portfolio of drug-resistance mutations than surveillance systems based only on treatment...
