A good night’s sleep can work wonders for both mind and body. But what is it that determines how much we need to sleep, and what can cause us to sleep more deeply?

The invention uses ultrasound-responsive nanobubbles to deliver treatment to targeted areas of a person’s body, avoiding side effects associated with traditional osteoporosis treatments, such as osteonecrosis (delayed healing of the jawbone) and gastrointestinal problems.

Megan McCain and postdoc Megan Rexius-Hall have engineered a microscale model that might one day serve as a testbed for personalized heart drugs

Consistent exercise can change not just waistlines but the very molecules in the human body that influence how genes behave, a new study of twins indicates.

Microscopic fragments of environmental DNA were found in Ice Age sediment in northern Greenland. Using cutting-edge technology, researchers discovered the fragments are one million years older than the previous record for DNA sampled from a Siberian mammoth bone.

Researchers from Tokyo Medical and Dental University (TMDU) find that spheroids grown in suspension mature into human intestinal organoids when transferred to a bioreactor and differentiate into complex intestinal tissue upon transplantation

A study published in Nature Metabolism and led by Prof. ZHAI Qiwei from the Shanghai Institute of Nutrition and Health of the Chinese Academy of Sciences has revealed that an increase of Lactobacillus and its metabolites after dieting enhanced intestinal lipid absorption and led to quick fat accumulation and obesity in mice. It also showed that this effect could be prevented by a high-protein diet or specific antibiotics that inhibit the growth of intestinal Lactobacillus.
