Study reveals a direct correlation between fat browning and consumption of flavan 3-ols

In cold conditions, brown adipose tissue (BAT) or brown fat generates heat to keep the body warm. Compared with white adipose tissue, BAT has more mitochondria - subcellular organelles associated with energy production - which allows it to burn calories and produce heat by activating the mitochondrial uncoupling protein 1 (Ucp-1).

Study uncovers a class of microbial enzymes that drive ulcerative colitis

Ulcerative colitis, a subtype of inflammatory bowel disease, is a chronic ailment of the colon affecting nearly one million individuals in the United States. It is thought to be linked to disruptions in the gut microbiome - the bacteria and other microbes that live inside us - but no existing treatments actually target these microorganisms.

Scientists describe a smell sensory map in fruit flies

The distinctive smell of a flower.. the unmistakable aroma of coffee… the dangers linked with inhaling smoke fumes. Sensory systems have evolved to provide us with immediate, finely tuned information about the world around us, whether they are colors processed through our visual system or certain pitches interpreted through our hearing.
