Bound For Destruction: Ubiquitination Protects Against Improper Notch
The Notch pathway is an important molecular signaling mechanism whose existence has been known, or at least hinted at, for nearly a century since the identification of a mutant strain of Drosophila fruit flies with "notched"wings in Thomas Hunt Morgan's lab in 1910.Notch is activated by a protease that is present ubiquitously in the cell membrane. What has long remained a mystery, however, is the question of how Notch receptors that have not been activated by a ligand are protected from digestion by that protease. NASA'S Live Tropical Sea Surface Temperature Web Site Gives Climate, H
Sea surface temperatures give scientists information about ocean currents, climate, climate change and how a hurricane may evolve. Now, NASA has a Web page that provides frequent updates on changing ocean temperatures. Hypochondriacal Electromagnetosis
Can Wi-Fi signals make you ill? Newshounds pore over the available literature, but miss something interesting about the claims themselves. In Gear Factor. Investigational Transplant Drug Effectively Preserves Kidneys While Av
Physician-researchers at Emory University in Atlanta have shown an investigational medication, known as LEA29Y (belatacept), is effective in preserving transplanted kidney function while at the same time avoiding the toxic side effects that are common in the currently used long-term, immunosuppressive transplant medications. Sticky Mutant Proteins Implicated In Lou Gehrig's Disease
A new study indicates that mutant Cu/Zn superoxide dismutase (SOD1) enzymes that are associated with an inherited form of Lou Gehrig's disease cause the protein to become sticky in tissues. Partial unfolding of the mutant protein can expose hydrophobic residues that may promote abnormal interactions with other proteins or membranes in the cell. Scientists Reveal How Disease Bacterium Survives Inside Immune System
New research on a bacterium that can survive encounters with specific immune system cells has strengthened scientists' belief that these plentiful white blood cells, known as neutrophils, dictate whether our immune system will permit or prevent bacterial infections. A paper describing the research was released today online in The Journal of Immunology. Making Delicious Snack Foods With Extra Healthful Fiber
Trying to get more fiber in your diet? Munching on cookies or tortillas probably doesn't come to mind. But now scientists are researching ways to add fiber to the foods we love without changing what we like about our favorite snacks. Researchers will be experimenting with extrusion processing to make fiber-enriched flour taste like the kind used in most cookies and tortillas, so that manufacturers can make a more healthful snacking alternatives that consumers want to eat. Earth Is Smaller Than Assumed
Geodesists have remeasured the size of the Earth and found that the blue planet is some millimeters smaller than previously assumed. The results are important, for example, to be able to demonstrate a climate contingent rise in sea level. [Ironic] LONDON: A jailed cocaine dealer is working as Santa Claus on
John Tams, who dons beard, boots and red suit to work in a cafe's Christmas grotto, said he wanted to give something back to the community...
