Phys.org / A hidden step before meiosis could reshape efforts to treat infertility
In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a group of specialized cells, known as "germ cells," which will later form sperm and eggs, these inherited ...
Phys.org / Scientists unlock a massive new 'color palette' for biomedical research by synthesizing non-natural amino acids
Ozempic has been making headlines for its remarkable success in treating obesity and diabetes. Yet it is just one in a rapidly growing class of drugs called peptide therapeutics that sits between small molecules (like aspirin) ...
Medical Xpress / Red blood cells soak up sugar at high altitude, protecting against diabetes
Scientists have long known that people living at high altitudes, where oxygen levels are low, have lower rates of diabetes than people living closer to sea level. But the mechanism of this protection has remained a mystery. ...
Phys.org / New catalyst unlocks aluminum's ability to switch between oxidation states
Aluminum's journey has been remarkable, going from being more expensive than gold to one of the most widely used materials, from beverage cans to window frames and car parts. Scientists from the Southern University of Science ...
Medical Xpress / Anxiety and depression are widespread in adults with disabilities. What the data show
Adults with intellectual and developmental disabilities, such as autism and Down syndrome, experience substantially higher rates of anxiety and depression than the general population of adults, researchers report in JAMA ...
Phys.org / What 'housane' rings are and why a light-powered route may matter for drugs
When developing new drugs, one thing is particularly important: finding and producing the right molecules that can be used as active ingredients. The key elements of some drugs, such as penicillin, are small, tri- or quadripartite ...
Medical Xpress / Big feelings: Five ways parents can help kids learn to regulate their emotions
Parenting can be hard and can feel especially overwhelming when children have strong emotions, such as anger, frustration or excitement, that they are not always able to regulate on their own.
Medical Xpress / Fiber-free processed foods hit emotional memory fast, especially in older brains
Past studies in animals have shown that a highly processed diet is linked to memory problems and inflammation in the aged brain—and the effect can happen fast, after just three days of poor eating.
Phys.org / Rare fossil at Montana museum records Tyrannosaurus attack
A fossil on display at Montana State University's Museum of the Rockies reveals how dinosaurs in the Tyrannosaurus genus may have subdued prey, and the specimen is the focus of a new collaborative research publication between ...
Medical Xpress / Physical function is a crucial predictor of survival after heart failure, mortality risk model indicates
Monitoring and treating heart failure (HF) is a challenging condition at any age. Several models, such as Atrial fibrillation, Hemoglobin, Elderly, Abnormal renal parameters, Diabetes mellitus (AHEAD), and BIOlogy Study to ...
Medical Xpress / Second pregnancy uniquely alters the female brain, study shows
Researchers at Amsterdam UMC have discovered that a second pregnancy alters the female brain. Previous research from the same group had already demonstrated the impact of a first pregnancy on the female brain. The new results ...
Phys.org / Forest loss can make watersheds 'leakier,' global study suggests
Forest loss does more than reduce tree cover. A new global study involving UBC Okanagan researchers shows it can fundamentally change how watersheds hold and release water. The research, published in the Proceedings of the ...
