KentuckyFC writes "Having created quantum superpositions of photons, atoms, and even molecules, scientists are currently preparing to do the same for larger objects — namely viruses. The technique will involve storing a virus in a vacuum and then cooling it to its quantum-mechanical ground state in a microcavity. Zapping the virus with a laser then leaves it in a superposition of its ground state and an excited one. That's no easy task, however. The virus will have to survive the vacuum, behave like a dielectric, and appear transparent to the laser light, which would otherwise tear it apart. Now a group of researchers has worked out that several viruses look capable of surviving the superposition process, including the common flu virus and the tobacco mosaic virus. They point out that after creating the superposition, scientists will be able to perform the Schrodinger's Cat experiment for the first time, which should be fun (but less so for the virus)."

On Friday, NASA launched the Ocean Surface Topography Mission/Jason 2 satellite into orbit to begin a detailed study of ocean currents, sea-surface height, and surface topology. Scientists hope to use the data gathered by Jason 2 in order to better understand weather patterns and global warming. Further details about the mission objectives (PDF) are also available. Quoting NASA's press release: "Combining ocean current and heat storage data is key to understanding global climate variations. OSTM/Jason 2's expected lifetime of at least three years will extend into the next decade the continuous record of these data started in 1992 by NASA and the French space agency Centre National d'Etudes Spatiales, or CNES, with the TOPEX/Poseidon mission. The data collection was continued by the two agencies on Jason 1 in 2001. Compared with Jason 1 measurements, OSTM/Jason 2 will have substantially increased accuracy and provide data to within 25 kilometers (15 miles) of coastlines, nearly 50 percent closer to shore than in the past."

dstates points out a recent article from guardian.co.uk which discusses a new method by which to recover fingerprints from metal. The method relies on corrosion caused by sweat and other biological residues on the metal's surface. Quoting: "The patterns of corrosion remain even after the surface has been cleaned, heated to 600C or even painted over. This means that traces of fingerprints stay on the metal long after the residue from a person's finger has gone. The chemical basis of the change is not yet clear, but [Dr. John Bond] believes it is corrosion by chloride ions from the salt in sweat. These produce lines of corrosion along the ridges of the fingerprint residue. When the metal is heated, for example in a bomb blast or when a gun is fired, the chemical reaction actually speeds up and makes the corrosion more pronounced."

Piranhaa"I currently use an IPTV box that runs software by Minerva Networks. When you ssh into the box, you are greeted with a BusyBox v1.00 (ash) shell. It's clearly running a flavor of Linux (uname -apm outputs: Linux minerva_10_0_3_99 2.4.30-tango2-2.7.144.0 #29 Wed Mar 16 16:16:16 CET 2005 mips unknown). However, when you look at their Web site there is no publicly available source code. Since the GPL in both BusyBox and the Linux kernel require that anyone using and distributing the binaries of this software make source available to everyone, what would one do in order to enforce this? I've personally emailed Minerva and left voicemails with no reply."
