Submission + - Dreams Are Virtual Reality Threat Simulation

Submitted by
Time Slows Down
Time Slows Down writes: "Psychology Today has an interesting story on a new theory of why we dream. Finnish psychologist Antti Revonsuo believes that dreams are a sort of nighttime theater in which our brains screen realistic scenarios simulating emergency situations and providing an arena for safe training. "The primary function of negative dreams is rehearsal for similar real events, so that threat recognition and avoidance happens faster and more automatically in comparable real situations," he says. We have 300 to 1,000 threat dreams per year — one to four per night and just under half are aggressive encounters: physical aggression such as fistfights, and nonphysical aggression such as verbal arguments. Faced with actual life-or-death situations — traffic accidents, terrorist attacks, street assaults — people report entering a mode of calm, rapid response, reacting automatically, almost without thinking. Afterward, they often say the episode felt unreal, as if it were all a dream. "Dreaming is a sensitive system that tries to pay much attention to the threatening cues in our environment," Revonsuo says. "Their function is to protect and prepare us.""

Submission + - Communities of Mutants Form as DNA Testing Grows (nytimes.com) 1

Submitted by GeneRegulator
GeneRegulator writes: The NY Times is running a story on communities that are forming around kids with rare genetic mutations. New technology that can scan chromosomes for small errors is being applied first to children with autism and other "unexplained developmental delays." It turns out that many of them have small deletions or duplications of DNA, and doctors creating a whole new taxonomy of syndromes with names like 16p11.2 and 7q11.23 that refer to the affected region of the genome. Meanwhile, hundreds of little groups are forming around the banner of their children's shared mutations. As new research shows that many of us have small deletions and duplications of DNA that separate us from our parents, and that many of these "copy number variants" contribute to skills and senses the families described in the story may presage the formation of all sorts of "communities of the genetically rare" in the general population, not just amongst the developmentally delayed.

Submission + - FireWire spec to boost data speeds to 3.2 Gbps 1

Submitted by Stony Stevenson
Stony Stevenson writes: A new set of specs for data transfer technology will quadruple top speeds to 3.2 Gbps. Formally known as IEEE 1394, the technology is called FireWire by Apple and i.LINK by Sony. The new version is called S3200 and builds on the earlier specification approved by the IEEE, according to the trade association that is preparing to unveil the details this week. The technology will be able to use existing FireWire 800 cables and connectors while delivering a major boost in performance. "It will probably go into storage products first," said 1394 Trade Association spokesman Richard Davies in an e-mail Wednesday. "It should turn up in set-top boxes and maybe Blue-ray devices, too. It's too soon to tell how fast consumer electronics makers might adopt it."
