No matter how heavy the traffic load, it always has the same number of lanes. In the brain, there is a dynamic change that allows certain pathway...Scientists devise way to measure RNA synthesis on the fly in a live cell

Cluzel compares the unaccounted-for complexity of biological function today to the situation 20 years ago in astronomy, when scientists realized that the celestial objects visible to them did not contain enough gravity to explain the motion of galaxies.

"You want to be sure it doesn't detect another organism that shares similar properties," said Nugen.

This compares favorably with the reduction obtained by the administration of rosiglitazone, a widely-prescribed treatment for type 2 diabetes that acts by sensitizing cells to insulin.

"The skin of fungi microbes is what enables them to stick to your organs, and thus become pathogenic. It also enables the fungi to stick together, which is desirable for fermentat......enced the short arms of chromosomes 3 and 10. Wing compares the rice genome, with its 12 chromosomes, to a book with 12 chapters, written in an alien language.

...ng glucose's role in health and disease, Montminy compares the human body to a hybrid car that runs on a mix of fuels depending on its activity status: gas, or glucose, is used for high-energy activities, and battery power, or body fat, for low-energy activities. During the day, when food refuels the "gas ta...Computers close in on protein structure prediction

Baker compares the computer simulations of the proteins to the problem of trying to find the lowest point on the surface of the Earth for the first time. A simple way to find the lowest place on the planet is to send out as many explorers as possible. The more expl...Marine bacterium suspected to play role in global carbon and nitrogen cycles
