Scientists identify the genes required for the biosynthesis of carthamin

Carthamin is a red pigment that stems from the yellow-orange corollas of safflower. Its usage as a red colorant can be traced back to ancient Egypt. In Japan it is named "beni" and has been used for dyeing textiles, coloring cosmetics and food, and as an herbal medicine for over 1400 years.

Research reveals link between high-fat diet, gut microbiota and cardiovascular disease

A high-fat diet disrupts the biology of the gut's inner lining and its microbial communities -; and promotes the production of a metabolite that may contribute to heart disease, according to a study published Aug. 13 in the journal Science.
