Not long ago, we discussed Cassini's mission to "skeet-shoot" Saturn's moon Enceladus in order to take high-resolution pictures as close to the surface as possible. Well, NASA scientists found what they were looking for. A newly released mosaic shows 300-meter-deep fractures in Enceladus' surface which are the source of enormous icy plumes that periodically erupt into space, reaching hundreds of kilometers from the moon's surface. Another picture shows one of the fractures in closer detail.

Thanks to everyone who tested on Friday, as well as to all of SourceForge's netops crew, our corporate overlords at SourceForge for paying the bill, and of course all the engineers on Slashteam- Jamie McCarthy, Tim Vroom, Chris Nandor, Chris Brown, and Scott Collins, we are now running on the new iron in a cage in Chicago. We'll run a story in a few days about the ridiculously overpowered new hardware we have now, but now is the part of sprockets where we dance.

siddster notes an account up at Wired of research indicating that brain scanners can see your decisions before you make them. "In a study published Sunday in Nature Neuroscience, researchers using brain scanners could predict people's decisions seven seconds before the test subjects were even aware of making them... Caveats remain, holding open the door for free will... The experiment may not reflect the mental dynamics of other, more complicated decisions... Also, the predictions were not completely accurate. Maybe free will enters at the last moment, allowing a person to override an unpalatable subconscious decision."

dratcw writes "The first commercial LAN was based on ARCnet technology and was installed some 30 years ago, according to a ComputerWorld article. Bob Metcalfe, one of the co-inventors of Ethernet, recalls the early battles between the different flavors of LAN and says some claims from the Token Ring backers such as IBM were lies. 'I know that sounds nasty, but for 10 years I had to put up with that crap from the IBM Token Ring people — you bet I'm bitter.' Besides dipping into networking nostalgia, the article also quotes an analyst who says the LAN may be nearing its demise and predicts that all machines will be individually connected to one huge WAN at gigabit speeds. Could the LAN actually be nearing the end of its lifecycle?"

Reservoir Hill writes "Zombie insects might sound like a B-movie plot device (quicktime video) but to the emerald cockroach wasp (Ampulex compressa), they're a tried and tested way to provide food for their hungry larvae. The wasp relies on cockroaches for its grisly life cycle but unlike many venomous predators, which paralyze their victims before eating them, the wasp's sting leaves the cockroach able to walk, but unable to initiate its own movement. Researchers have discovered that the wasps sting the cockroaches once to subdue them, then administer another, more precise sting right into their victim's brain. The venom works to block a neurotransmitter called octopamine with a similar action to dopamine, which is involved in preparations to execute complex behaviors such as walking. Then the wasp grabs the cockroach's antenna and leads it back to the nest 'like a dog on a leash', says one researcher. The team found that they could restore spontaneous walking behavior in stung cockroaches by giving them a compound that reactivates octopamine receptors in the insects' central nervous system. Researchers were also able to create their own zombies by injecting unstung cockroaches with a compound that blocks the receptors producing a similar effect to that of the venom."

Verunks writes "A federal judge Monday ordered the White House to preserve copies of all its e-mails in response to two lawsuits that seek to determine whether e-mails have been destroyed in violation of federal law. The issue surfaced in the leak probe of administration officials who disclosed Valerie Plame's CIA identity. ' The Federal Records Act details strict standards prohibiting the destruction of government documents including electronic messages, unless first approved by the archivist of the United States. Justice Department lawyers had urged the courts to accept a proposed White House declaration promising to preserve all backup tapes. The judge's order "should stop any future destruction of e-mails, but the White House stopped archiving its e-mail in 2003 and we don't know if some backup tapes for those e-mails were already taped over before we went to court. It's a mystery," said Meredith Fuchs, a lawyer for the National Security Archive.'"

Amigan writes "Professor Jerzy Rozenblit at the University of Arizona was awarded $2.2Million to develop software to predict the unpredictable — specifically relating to volatile political and military situations." From the article: "The software will predict the actions of paramilitary groups, ethnic factions, terrorists and criminal groups, while aiding commanders in devising strategies for stabilizing areas before, during and after conflicts. It also will have many civilian applications in finance, law enforcement, epidemiology and the aftermath of natural disasters, such as hurricane Katrina."

mdsolar writes "In a first for the US, one of three nuclear reactors at the Browns Ferry nuclear plant in Alabama has been shut down because the Tennessee River is too hot to provide adequate cooling for the waste heat produced by the reactor. This is happening as the TVA faces its highest demand for power ever, reports the Houston Chronicle. This effect has been seen in Europe in the past, forcing reduced generation, but the US has until now been immune to the problem. The TVA will buy power elsewhere and impose higher rates, blaming reduced river flow as a result of drought."
