Being undernourished or overweight are no longer separate public health issues. A new article details how more than one in three low- and middle-income countries face both extremes of malnutrition -- a reality driven by ...

Patients with acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML) who are treated with anthracyclines are at a heightened risk of heart failure -- most often within one year of exposure to the chemotherapy...

Gut cells that normally tell the brain and the rest of the body what's going on after a meal shut down completely for a few hours after a high-fat meal, a team of researchers discovered in zebrafish. Enteroendocrine cell...

Researchers have found for the first time that less muscle and more body fat may affect how flexible our thinking gets as we become older, and changes in parts of the immune system could be responsible.

Researchers are studying glycine receptors, particularly glycine receptor alpha-4 (Glra4), during development. They demonstrated, in a new study, that Glra4 is not a brain exclusive gene, as was believed, but on the cont...

Investigators analyzed the impact of 10 dietary factors -- including consumption of fruits and vegetables, nuts and seeds, processed meats and more -- and estimated the annual CMD costs of suboptimal diet habits.

Researchers develop the foundation for direct sequencing of individual proteins.

Macrophages have 2 faces: In healthy tissue, they perform important tasks and support their environment. However during an infection, they stop this work and hunt down the pathogens instead. Upon coming into contact with...

An emerging technology involving particles that absorb light and turn it into localized heat sources shows great promise in several fields, including medicine. This heating must be carefully controlled however, and the a...

Researchers have discovered signatures in brain activity that allow them to tell old and new memories apart. The team analyzed recordings from mouse brains using a machine-leaning algorithm, which was able to accurately ...

Gene therapy is fighting to enter mainstream medicine. With sickle cell disease, the fight is heating up. Roughly two years ago, the FDA made the historic decision to approve the first gene therapy in the US, finally rea...

A new design of optical chips enables light to experience multiple dimensions, which could underpin versatile platforms for advanced communications and ultra-fast artificial intelligence technologies.

A wearable monitoring device to make treatments easier and more affordable for the millions of people with swallowing disorders is about to be released into the market.

A large new study finds that women who lost weight after age 50 and kept it off had a lower risk of breast cancer than women whose weight remained stable, helping answer a vexing question in cancer prevention.

Particles can sometimes act like waves, and photons (particles of light) are no exception. Just as waves create an interference pattern, like ripples on a pond, so do photons. Physicists from the National Institute of St...

She was thought to live nearly 5,000 years ago...but she likely never existed.

Infrared cameras detect people and other objects by the heat they emit. Now, researchers have discovered the uncanny ability of a material to hide a target by masking its telltale heat properties.

Two physicists from the University of Luxembourg have now unambiguously shown that quantum-mechanical wavelike interactions are indeed crucial even at the scale of natural biological processes.

An emerging technology involving tiny particles that absorb light and turn it into localized heat sources shows great promise in several fields, including medicine. For example, photothermal therapy, a new type of cancer...

Daytime exposure to bright lights may improve a person's quality of sleep, and could reduce depressive symptoms and agitation associated with dementia

More than 100 exoplanets and the stars they orbit have just been officially named by a public vote. The names reference woolly hats, bush pigeons, coffee and van Gogh

Cabinet greenlights $600-million Hyper-Kamiokande experiment, which scientists hope will bring revolutionary discoveries --
