Mayo discovers protein as potential tactic to prevent tumors

... or apoptosis. Cells have the genetic knowledge to sacrifice themselves for the greater good of the organism rather than to pass on errant genetic codes that can lead to disease. Genetic errors that sneak past the cell's quality control check-points can make the cell prone to develop into cancer. How It Ha...

New HIV statistics indicate increasing toll of AIDS on African American community

...ack Caucus' Health Braintrust. "Are we willing to sacrifice another half-million African-American lives to this entirely preventable disease? It is up to the members of the newly elected 110th Congress to answer this question." Report Recommendations African-Americans, Health Disparities and HIV/AIDS: ...

Using nanoparticles, in vivo gene therapy activates brain stem cells

...the brain cells expressing genes without having to sacrifice the animal. Then the UB researchers decided to go one step further, to see if they could not only observe, but also manipulate the behavior of brain cells. Their finding that the nanoparticles successfully altered the development path of neural stem...

To sea or not to sea: When it comes to salmon sex, size sometimes doesn't matter

...o not migrate to sea at all," he says. "These fish sacrifice the growing opportunities at sea for the relative safety of freshwater, and males are more inclined to remain than females. This difference is related to the fact that reproductive success in females is linked to the ability to produce numerous large...

Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals

...nd at high resolution, investigators don't need to sacrifice animals and perform laborious and costly analysis. To trigger living cells into producing their own contrast agent, Ahrens gave them a gene that produces a form of ferritin, a protein that normally stores iron in a non-toxic form. This metalloprotei...
