Coffee may help lower your risk of having a stroke, especially if it is a regular part of your diet, according to research published in Stroke: Journal of the American Heart Association.

Green tea also, though it's unclear how green tea affects stroke risks. A compound group known as catechins may provide some protection. Catechins have an antioxidant anti-inflammatory effect, increasing plasma antioxidant capacity and anti-thrombogenic effects.  Some chemicals in coffee include chlorogenic acid, thus cutting stroke risks by lowering the chances of developing type 2 diabetes.

Terahertz (THz) radiation, in the electromagnetic spectrum between microwaves and infrared light, is rapidly finding important uses in medical diagnostics, security, and scientific research. 

But researchers are pursuing answers regarding potential human health risks. 

CITES today overruled objections from countries like Japan, China and India and listed five species of highly traded sharks under the CITES Appendices, along with both manta rays and one species of sawfish. 

Japan, India and Gambia challenged the Committee's desire to list the oceanic whitetip shark, while Grenada and China objected to listing three hammerhead species. 

Proponents of the various listing proposals include the USA, the EU, Australia, Brazil, Colombia, Comoros, Costa Rica, Croatia, Ecuador, Egypt, Honduras and Mexico. The shark and ray proposals received more than the two-thirds majority of votes necessary for adoption while the sawfish listing succeeded by consensus.

BANGKOK -- March 14, 2013 -- The following statement was issued today by WCS President and CEO Cristian Samper:

 Schizophrenia is thought to have a substantial genetic background which is also, to some extent, population-specific. Genome-wide searches have revealed many numerous genomic variants with weak effects, but the remaining 'missing heritability' is unknown. Scientists hypothesize that it may be partly explained by rare variants with large effect.  

Since the 1960s, biologists have been hunting for substances made by the body that might accumulate in abnormally high levels to produce the symptoms associated with schizophrenia. In particular, there was a search for chemicals that might be related to the hallucinogens phencyclidine (PCP) or lysergic acid diethylamide (LSD), which could explain the emergence of psychotic symptoms in schizophrenia.
