Universe's stringy birth revealed by young Czech scientist in EURYI winning project
... at the cutting edge of analytical reason. This is why it should interest lay people as well, insisted Schnabl. The very general public can be interested if they enjoy watching mankind's advances in understanding some of the deepest questions about the nature of our universe.

Part of the reason why this is an interesting discovery is that people think of coelacanths animals as archetypal living fossils, said Matt Friedman, evolutionary biology graduate student at Chicago and lead author of the paper. But its a common misconception. If you look ...How a pain in the neck could be bad for your blood pressure

By identifying the pathways we can see why these treatments might work and it could also explain why some people suffering whiplash injuries may experience a change in their blood pressure.

Such information should lead to new ideas on how to manipulate this system in a variety of blood diseases....JCI table of contents: August 1, 2007
...now added the EGF gene to this list and identified why one mutation in this gene causes hypomagnesemia. In the study, René Bindels and colleagues from Raboud University Nijmegen Medical Center in The Netherlands, observed that a mutation in the EGF gene was the cause of hypomagnesemia in two individual...U-M researchers find family of 'on switches' that cause prostate cancer

Learning to fly is easy, if you are a bird. But why is it that birds learn so easily how to fly" It is well known that birds learn through practice, and that they gradually refine their innate ability into a finely tuned skill. According to a new theory by Dr Stone of Sheffield University, skills such...Genomics study provides insight into the evolution of unique human traits
...er expansion of a gene called AQP7 could explain why humans have evolved the capacity for endurance running. AQP7 , or aquaporin 7, plays a role in transporting water and glycerol across membranes. Therefore, it may facilitate the mobilization of glycogen (energy) stores during long periods of intens...Researchers find pathway that controls cell size and division

When fish oil binds to one of the two sites, it may prepare the other site to bind more easily to vegetable oil, ...Boston Univeristy bioengineers devise 'dimmer swith' to regulate gene expression in mammal cells
