The Shapes Of Life: NIGMS Project Yields More Than 1,000 Protein Structures

The Protein Structure Initiative (PSI), a national program aimed at determining the three-dimensional shapes of a wide range of proteins, has now determined more than 1,000 different structures. These structures will shed light on how proteins function in many life processes and could lead to targets for the development of new medicines. The PSI is a 10-year, approximately $600 million pr...

Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection

New research on prions, the infectious proteins behind "mad cow" disease and Creutzfeld-Jakob disease in humans, suggests that the ability of prions in one species to infect other species depends on the shape of the toxic threadlike fibers produced by the prion. Two studies on the topic appear in the 8 April issue of the journal Cell. Although research suggests that prions from one specie...

Scientists reveal the shape of a protein that helps retroviruses break into cells

The biggest mass extinction in Earth history some 251 million years ago was preceded by elevated extinction rates before the main event and was followed by a delayed recovery that lasted for millions of years. New research by two University of Washington scientists suggests that a sharp decline in atmospheric oxygen levels was likely a major reason for both the elevated extinction rates and the v...

Body can reshape heart damage

Using the male chromosome as a marker, researchers studying eight cross-gender heart transplants from New York Medical College have discovered that the body can actively reshape the heart after injury.// The research explodes the long-standing belief that the heart cannot repair itself and the finding has implications for heart disease treatment. The realization that the body works...

Genetics Has A Major Role To Play In Body Shape.

Scientists in a major breakthrough in the study of treating obesity have identified a gene FOX gene,// which is associated with gain in weight. This now explains why people despite not eating too much tend to put on weight and turn obese. The logical sequence for obesity is input of food being greater than the energy expenditure, but in certain situations this is not the case....
