...no overall inhibition of tumor growth. The tumor's center became "necrotic" or populated with dead cells, but the perimeter of the tumor continued to grow. In fact, blocking HIF-1 before radiation was detrimental to radiation's effects: it prevented cancer cells from engaging in the very behaviors that rad...

Digging in the dirt for life's biochemical foundations

...ty and the U.S. Department of Agriculture research center near Philadelphia, tagged nitrogen with easy-to-spot atomic markers and then watched as it traveled from soil to fungus to plant roots. Many had assumed that the fungus would play a modest role. The team found, however, that the fungus acts more lik...

Shampoo detergent added to paint makes surfaces self-sterilizing

...Public buildings and especially schools are at the center of the epidemiological web for spreading common upper respiratory diseases that cost the U.S. hundreds of billions of dollars annually in lost productivity. While it has long been known that our coinage possesses the quality of being self-sterilizing...

NHGRI Selects 13 More Organisms for Genome Sequencing

Researchers discover how malaria parasite disperses from red blood cells

...g, with the parasites visible as a sphere near the center of the cell. (A diagram of the entire sequence appears at http://www.nichd.nih.gov/new/releases/malaria_graphic.cfm .) The cell's lop-sided appearance probably results from destruction of the cytoskeleton, the molecular scaffolding that helps the ...

Surgical Robot 'Scrubs In' At UNC, May Be More Precise Than Conventional Surgery

These devices, based on aluminum gallium nitride (AlGaN) compound semiconductors, have a photocurrent gain of more than 700. The tiny-sized APDs should be capable of effic...

Hunger in America rises by 43 percent over last five years

New study to explore cellular circuitry

...e yeast cell. Over the last four years, medical center researchers created a library of 6000 clones, or exact copies of the genes of the yeast cell, one clone for each known protein present in the cell. What makes the set of clones useful is that each one manufactures large amounts of a single protein w...

Science's Breakthrough of the Year: Watching evolution in action

... A short, intense pulse of radiation from near the center of the Milky Way, recorded on 27 December 2004, may be the result of a short gamma ray burst -- a rapid merger of two ancient neutron stars or a neutron star and a black hole.
