Researchers discover mechanism for multiplying adult stem cells

...ons, it could be a powerful tool. "This may allow you to expand adult stem cells for therapy," observes Hochedlinger. "For instance, you could remove a person's skin tissue, put it in a dish, isolate the skin stem cells, then subject it ...

When it comes to cell entry, being average has its advantages

... used in everything from cameras to clothing. "If you know how viruses get into cells, you know how to better design drugs to keep them out," said L.B. Freund, professor of engineering at Bro...

Caloric restriction won't dramatically extend life span in humans: UCLA research

...heard someone say caloric restriction may not make you live forever, but it sure would seem like it. Try ...rs to be a more sensible solution. "With mice, if you restrict their caloric intake by 10 percent, they live longer than if they have unlimited access to ...

Anthrax test, developed by army and CDC, receives FDA approval

... inoculated with suspicious anthrax colony growth, you can see clear zones where the B. anthracis cells have been destroyed--whereas other bacterial cells grow unaffected." Well before the anthrax attacks of 2001, scientists at USAMRIID and the CDC recognized the need for an FDA accepted method for iden...

Researcher gets NSF grant to create mutant maize lines

... the breadth of uses for maize, Brutnell adds. "If you walk into a grocery store, 80 percent of the products on the shelves contain maize, in the form of starch, sugar, meal or oil," he says. "It's a $23 billion-a-year industry in the U.S. alone." Brutnell's colleagues include Erik Vollbrecht and Volker...

Discovery of an American salamander where it shouldn't be: Korea

...ime is probably here in the Pacific Northwest. So, you have a major biogeographical question: How in the world could it have gotten there? Previously unknown but still living vertebrate species like this can provide us with key information on the history of life on earth." Karsen made the discovery in A...

Biologists determine genetic blueprint of social amoeba

...s," says Kuspa. "You can make direct analogies, or you could learn general principles about how cells regulate their behavior. Both things will apply in the studies we do." He and the other members of the international sequencing team found that there are more protein coding genes in the organism than t...

Researchers develop new method for facile identification of proteins in bacterial cells

... be performed much faster and more economically if you have more needles--and that's exactly what our method is based on," explained Dr. Halden. "Instead of spending a lot of time and resources on eliminating the background noise to find the signal, our method increases the signal upfront so that it stan...

Wild grasses and man-made wheats advance research capabilities

...High Plains wheat. But to get genetic variability, you cross state lines or even into other countries. The next step would be to cross species, if the desired traits can't be obtained in a wheat-to-wheat cross." A wild grass collection being mined for its genetics has 716 lines of wheat relative species...
