Cortisol is a hormone made by the adrenal cortex (the outer layer of the adrenal gland). It helps the body use glucose (a sugar), protein, and fats. Cortisol made in the laboratory is called hydrocortisone. It is used to treat many conditions, including inflammation, allergies, and some cancers. Cortisol is a type of glucocorticoid hormone.
In this age of highly realistic computer games and increasingly popular social networks, social exclusion in virtual worlds is becoming more and more socially significant, as is demonstrated by the growing number of "cyber mobbing" cases.

The name of the gene is Armc5, for Armadillo repeat containing 5. Until now, its function was unknown. After 10 years of research, a team at the University of Montreal Hospital Research Centrehas succeeded in deleting this gene in experimental mice and discovered that its loss gives rise to a heretofore unidentified syndrome.

A new Finnish study supports food recommendations for families with children in that women should avoid consuming large amounts of liquorice during pregnancy. The limit for safe consumption is not known.
James Cook University scientists have made a disturbing finding about some young Indigenous people's biological reaction to stress, but one that could help close the health gap for indigenous people.
A complete clinical and genetic profile of a rare inherited disorder, steroid 11-hydroxylase deficiency, which can cause genital masculinization in females, is being reported by an international group of researchers led by investigators at the Icahn School of Medicine at Mount Sinai.
Body shaming is a pervasive form of prejudice, found in cyber bullying, critiques of celebrities' appearances, at work and school, and in public places for everyday Americans.
