Scientists have uncovered how exercise directly influences brain health in Alzheimer's disease by pinpointing the exact brain cells affected. Using cutting-edge RNA sequencing and mouse models, researchers identified changes in specific cells like .. ...

A protective sugar coating on brain blood vessels, once thought to be insignificant, turns out to play a vital role in preventing cognitive decline. Restoring this layer reversed damage and memory loss in aging brains, offering a fresh approach to .. ...

Researchers at Johns Hopkins found that fragments of tumor DNA can appear in the bloodstream up to three years before a cancer diagnosis, offering a potentially revolutionary window for early detection and treatment.

Scientists have uncovered a previously unknown type of molecular motion inside DNA-based droplets: instead of spreading randomly, guest molecules advance in an organized wave. This surprising discovery opens the door to understanding how cells might ...

Viruses closely related to the deadly MERS coronavirus are lurking in bats and one group, known as HKU5, may be just one mutation away from making the jump to humans. A new study reveals how these viruses bind to cell receptors and even shows signs . ...

Tufts University scientists are aiming to revolutionize the future of weight loss drugs by engineering a new compound that targets four gut hormones instead of the usual one to three. These next-gen tetra-functional peptides may overcome the ...

A team at UC Davis has made a major leap in neurotechnology, enabling a man with ALS to speak again through a brain-computer interface that converts thoughts into speech in real time. Unlike prior systems that translated neural signals into text, ...

In a bold challenge to silicon s long-held dominance in electronics, Penn State researchers have built the world s first working CMOS computer entirely from atom-thin 2D materials. Using molybdenum disulfide and tungsten diselenide, they fabricated . ...

A scientific team has unlocked a new way to treat serious lung conditions by using specially designed nanoparticles to deliver genetic therapies straight to lung cells. This innovation could transform care for patients with cystic fibrosis or lung .. ...

A team of scientists has discovered a direct link between the smell of food and feelings of fullness at least in lean mice. This brain circuit, located in the medial septum and triggered by food odors, helps animals eat less by making them feel ...
