The first public revelation of the earliest continuous Semitic text ever deciphered has taken place at the Hebrew University of Jerusalem.

If you bend a knee or an elbow, the nerves in your limbs stretch but do not break. A University of Utah study suggests why: A gene produces a springy protein that keeps nerve cells flexible. When the gene was disabled in tiny nematode worms, their nerve cells literally broke.

Nerve cells glow fluorescent green in these microscope photographs showing part of a cross section of a tiny nematode worm. The horizontal green linear feature near the bottom of each photo is the worm equivalent of the spinal cord, while a secondary nerve cord is the horizontal green line near the top.

On Saturday, Hubble's main camera, the Advanced Camera for Surveys (ACS), stopped working. Until a solution, at least in part, can be found, Hubble will be returned to work with the remaining instruments.

The "spine" of the James Webb Space Telescope, called the backplane, is in great health for space, according to scientists and engineers.

Recent tests show that the backplane, which supports the big mirrors of the telescope, can handle its trip into space and operate correctly when the observatory launches in 2013.

Bioengineering researchers at UC San Diego have painstakingly assembled a virtual human metabolic network that will give researchers a new way to hunt for better treatments for hundreds of human metabolic disorders, from diabetes to high levels of cholesterol in the blood. This first-of-its-kind metabolic network builds on the sequencing of the human genome and contains more than 3,300 known human biochemical transformations that have been documented during 50 years of research worldwide.

British physicists have shared computer time with biologists around the world in an effort to combat malaria, which kills one million people annually.

Using an international computing grid spanning 27 nations, scientists analyze an average of 80,000 possible drug compounds against malaria every hour. In total, the network has processed more than 140 million compounds, with the United Kingdom's physics grid providing nearly half of the computing hours used.

The international WISDOM project, for World-wide In Silico Docking On Malaria, is designed to speed the search for anti-malarial drugs. The computers calculate the probability that molecules will dock with a target protein.
