Bacteria Sense Light, Use It To Regulate Virulence
August 28, 2007 04:39 PM - UC Santa Cruz
University of California, Santa Cruz - The bacteria that cause brucellosis can sense light and use the information to regulate their virulence, according to a study in the August 24 issue of the journal Science. The discovery comes after 120 years of research into the disease, which causes abortions in livestock and fevers in humans. Researchers found that two other bacteria, including a species that attacks plants, sense light using the same type of protein structure, and at least 94 more species possess the code for it in their DNA.

While vitamin D’s role in strengthening bones is well established, its links to cancer and immune-system malfunctions have only recently emerged. At the Harvard School of Public Health, nutrition experts say large segments of the population don’t get enough vitamin D and are urging the U.S. Food and Drug Administration to raise the daily recommended dose, from 400 international units to 800. For an update on what’s known so far about this important nutrient, the Harvard Public Health Review spoke with HSPH Professor of Nutrition and Epidemiology Edward Giovannucci.
Stem Cells Repair Rat Hearts Damaged By Heart Attack
August 27, 2007 08:43 PM - Justin Reedy , University of Washington
University of Washington - Researchers were successful in getting human-derived heart muscle cells to graft into rat hearts and thrive alongside the rat's normal heart muscle cells. Researchers were also able to use human-derived stem cells to grow a heart muscle graft in a rat heart damaged by a heart attack. The human-derived cells incorporated with scar tissue and regular heart muscle cells.
