Ted.com has a great sneak peek at Microsoft's new WorldWide Telescope project. In this video, presented by Roy Gould and Curtis Wong, you are able to see a combined view of satellites and telescopes from all over the planet and nearby space. The compiled image is rendered using Microsoft's new high-performance "Visual Experience Engine" that allows users to pan and zoom across the night sky seamlessly.

stemceller writes to tell us that a team of researchers at the University of Alberta claims to have discovered a gene capable of blocking HIV thereby preventing the onset of full blown AIDS. "Stephen Barr, a molecular virologist in the Department of Medical Microbiology and Immunology, says his team has identified a gene called TRIM22 that can block HIV infection in a cell culture by preventing the assembly of the virus. 'When we put this gene in cells, it prevents the assembly of the HIV virus," said Barr, a postdoctoral fellow. "This means the virus cannot get out of the cells to infect other cells, thereby blocking the spread of the virus.'"
