Tyrosinase inhibitors from terrestrial and marine resources
Posted by Washington Post: Juliet Eilperin on February 19th, 2016
ScienceDaily: Tyrosinase is a multifunctional copper-containing enzyme widely distributed in microorganisms as well as plants and animals which has a primordial role in melanin biosynthesis thus impacting on skin color and pigmentation. This particular enzyme has the ability to catalyze the hydroxylation of L-tyrosine toL-DOPA and further oxidize L-DOPA to dopaquinones which are considered as boosters of melanogenesis. Considering the medical and cosmetic sector, a great number of researches focused on the isolation...

Yes: Most of the time, public policy is a series of trade-offs: higher taxes or fewer services, more regulation or more freedom of action.

Posted by KIOS: Greg Allen on February 19th, 2016
KIOS: When people talk about Florida's Everglades, they often use superlatives: It's the largest protected wilderness east of the Mississippi River, and it's the biggest subtropical wetland in North America.
But it is also the site of a joint federal-state plan that is the largest ecosystem restoration effort ever attempted -- one that is beginning to pay off after decades of work.
The delivery of fresh water to long-parched areas of Everglades National Park is considered a vital restoration. It's...
