Report: How 10 top new technologies will help world reach globally-agreed goals by 2015
...ell as the mosquito that carries it. Knowledge of these
genomes, paired with the knowledge of the human genome, can be used to develop new drugs and vaccines. As well, the report forecasts the creation of microbicides for female-controlled protection against sexually transmitted disease like HIV, both wit...
Embryonic stem cells correct congenital heart defect in mouse embryos
... protein impairs the stem cells' ability to rescue these
embryonic mouse heart cells. These cells are very powerful, but also apparently very delicate." To understand the molecular basis of the rescue, the authors identified two important molecules implicated in signaling from the ES cells to the Id knock-...
Emory chemists develop bacteria that may help decaffeinate coffee
...affeine." Gallivan says that the idea is to supply these
bacteria with caffeine, and give each bacterium a piece of DNA from coffee plants that may encode the enzyme that will allow the bacterium to convert the caffeine to the theophylline it needs to survive. "At the end of the day, we will know that al...

types of drugs being developed; and unless there is a way to block Mrp4 when giving these
agents, the effectiveness of these
new agents could be significantly compromised." Other authors o...
'Junk' DNA may be very valuable to embryos
...es," says Dr. Knowles. "Also, random insertions of these
elements can introduce variation in genes, potentially altering their function." The researchers think that expression of retrotransposons during very early stages may contribute to the reprogramming of the mammalian embryonic genome, a prerequis...
Cells in retina found to behave like soap bubbles
...ain and again across the eye. Gaining insight into these
patterns can help researchers understand the interplay between genetics and physics in cell formation. "The cells we studied, those found in the retina of the fruit fly, adopt mathematically predictable shapes and configurations," said Richard W. Ca...
