Cellular jetlag seems to favor the development of diabetes

Like almost all light-sensitive living beings, human beings follow biological rhythms set on a period of about 24 hours. The circadian clock (from Latin "circa" and "dies", which means "about a day") therefore describes the ...

Low protein diets may improve blood sugar regulation in obesity

Diets that are very high in protein are linked to an increased risk for developing type 2 diabetes, and high protein levels have been correlated to poor insulin regulation. However, few studies have investigated whether decreasing ...

Neuron groups, not single cells, maintain brain stability

To compensate for erratic shifts and spikes in its neuronal communications, the brain relies on the stabilizing mechanism called "homeostasis"—the ability to maintain relatively stable equilibrium between different elements ...

Young vessels rejuvenate aged insulin-producing beta cells

A recent study published in the journal PNAS shows that young capillary vessels rejuvenate aged pancreatic islets. The finding challenges prevailing views on the causes of age-dependent impaired glucose balance regulation, ...

Proper stem cell function requires hydrogen sulfide

Stem cells in bone marrow need to produce hydrogen sulfide in order to properly multiply and form bone tissue, according to a new study from the Center for Craniofacial Molecular Biology at the Herman Ostrow School of Dentistry ...
