AFP has a good summary of the pre-touchdown jitters the Phoenix Mars Lander crew is living through. The spacecraft has been under way for 10 months. If the landing goes according to plan — and only about half of the three dozen such attempts have — mission controllers at the University of Arizona will receive radio signals from the Martian surface at 23:53 GMT. Here's the Mars mission home. You can (in theory) track the lander here, but at the moment the JPL Solar System Simulator is "experiencing technical difficulties."

FiReaNGeL alerts us to a huge development in virology and microscopy: by using a specialized microscope that only illuminates a cell's surface, scientists at Rockefeller University have watched, in real time, hundreds of thousands of molecules coming together in a living cell to form a single particle of HIV-1. A video is available on Rockefeller's front page. "By zeroing in at the cell's surface, the team became the first to document the time it takes for each HIV particle, or virion, to assemble: five to six minutes. 'At first, we had no idea whether it would take milliseconds or hours,' says Jouvenet. 'We just didn't know.' 'This is the first time anyone has seen a virus particle being born,' says Bieniasz, who is an associate professor and head of the Laboratory of Retrovirology at Rockefeller and a scientist at the Aaron Diamond AIDS Research Center. 'Not just HIV,' he clarifies, 'any virus.'"

Roland Piquepaille alerts us to work by US and Israeli researchers who have developed software that can identify the subject of an image characterized using only 256 to 1024 bits of data. The researchers said this "could lead to great advances in the automated identification of online images and, ultimately, provide a basis for computers to see like humans do." As an example, they've picked up about 13 million images from the Web and stored them in a searchable database of just 600 MB, making it possible to search for similar pictures through millions of images in less than a second on a typical PC. The lead researcher, MIT's Antonio Torralba, will be presenting the research next month at a conference on Computer Vision and Pattern Recognition.

An anonymous reader writes "My housemate uses an aggressive P2P client, that when in use makes the Internet unusable for everyone else connected to the network. After hearing about various ISPs shaping traffic to reduce P2P traffic, I was wondering if there was a solution for managing P2P traffic on a home network. I have a Linksys WRT54G available for hacking. Can Slashdot recommend a way to reduce the impact of P2P on my network and make it usable again?"
