To probe the secrets of inaccessible transmembrane proteins, researchers at the University of Pennsylvania School of Medicine have designed peptides that are able to bind to specific inner regions, using computer algorithms, and information from existing protein sequence and structure databases. This study looks at how the binding of these designed peptides affects the crucial first steps in blood clotting.

A study by scientists from King’s College London has found that relatively small amounts of omega-3 fatty acids from algae can lower blood pressure and could ultimately reduce the risk of cardiovascular disease. This form of omega-3, unlike fish oil, has the advantage of being both sustainable and acceptable to vegetarians.
