Submission + - Mutations Helped Humans Survive Siberian Winters (sciencemag.org)
sciencehabit writes: Researchers have identified three genetic mutations that appear to have helped humans surive in the frigid climate of Siberia over the last 25,000 years. One helps the body's fat stores directly produce heat rather than producing chemical energy for muscle movements or brain functions, a process called "nonshivering thermogenesis." Another is involved in the contraction of smooth muscle, key to shivering and the constriction of blood vessels to avoid heat loss. And the third is implicated in the metabolism of fats, especially those in meat and dairy products—a staple of the fat-laden diets of Arctic peoples.
Submission + - 58,000 Security Camera Systems Critically Vulnerable To Hackers (forbes.com) 1
Sparrowvsrevolution writes: Eighteen brands of security camera digital video recorders are vulnerable to an attack that would allow a hacker to remotely gain control of the devices to watch, copy, delete or alter video streams at will, as well as to use the machines as jumping-off points to access other computers behind a company's firewall, according to tests by two security researchers. And 58,000 of the hackable video boxes, all of which use firmware provided by the Guangdong, China-based firm Ray Sharp, are accessible via the Internet.
Early last week a hacker who uses the handle someLuser found that commands sent to a Swann DVR via port 9000 were accepted without any authentication. That trick would allow anyone to retrieve the login credentials for the DVR's web-based control panel. To compound the problem, the DVRs automatically make themselves visible to external connections using a protocol known as Universal Plug And Play, (UPNP) which maps the devices' location to any local router that has UPNP enabled--a common default setting. That feature, designed to allow users to remotely access their video files via remote PC or phone, effectively cuts a hole in any firewall that would expose the device to attackers, too. And security researcher H.D. Moore has been able to show that the flawed architecture isn't just used Swann, but instead effects every company that uses Ray Sharp's firmware. Neither Ray Sharp nor any of the eighteen firms have yet released a firmware fix.

Dogs Can Be Pessimistic 99
Not that it will change anything, but researchers at Bristol University say that your dog might be a gloom-monger. In addition to the downer dogs, the study also found a few that seemed happy no matter how uncaring the world around them was. "We know that people's emotional states affect their judgments and that happy people are more likely to judge an ambiguous situation positively. What our study has shown is that this applies similarly to dogs," said professor Mike Mendl, an author of the study and head of animal welfare and behavior at Bristol University.

Researchers Transmit Optical Data at 16.4 Tbps 2550km 126
Stony Stevenson writes "The goal of 100 Gbps Ethernet transmission is closer to reality with the announcement Wednesday that Alcatel-Lucent researchers have recorded an optical transmission record along with three photonic integrated circuits. Carried out by researchers in Bell Labs in Villarceaux, France, the successful transmission of 16.4 Tbps of optical data over 2,550 km was assisted by Alcatel's Thales' III-V Lab and Kylia, an optical solution company. The researchers utilized 164 wavelength-division multiplexed channels modulated at 100-Gbps in the effort."
Wave Powered Boat to Sail From Hawaii to Japan 152
CaroKann writes "In the middle of May 2008, Kenichi Horie, an adventurer known for such feats as paddling a pedal powered boat 4,660 miles from Hawaii to Okinawa in 1993, will be sailing a wave powered boat from Honolulu's Hawaii Yacht Club to the Kii Channel in Japan. The boat, a 3-ton catamaran named the Suntory Mermaid II, works by virtue of the fins located at the front of the boat. These fins "generate thrust force by moving up and down like the tails of dolphins and whales and absorbing the energy of the waves." The system can propel the boat no matter which direction the waves come from. Because the wave propulsion system absorbs the energy from the waves, a passenger on the boat will experience a smooth ride. With a top speed of about 5 knots, the journey is expected to take about 2 to 3 months."
NASA Plans to Smash Spacecraft into the Moon 176
djasbestos writes "NASA is planning to smash a spacecraft into the Moon in order to look for hydrogen deposits in the poles. More notably, it will impact with significantly greater force (100x, per the article) than previous Moon collisions, such as by the Lunar Prospector and Smart-1 probes. Admiral Ackbar was unreachable for comment as to the exact location and size of the Moon's thermal exhaust port."
FreeBSD 7.0 Release Now Available 229
cperciva writes "The first release from the new 7-STABLE branch of FreeBSD development, has been released. FreeBSD 7.0 brings with it many new features including support for ZFS, journaled filesystems, and SCTP, as well as dramatic improvements in performance and SMP scalability. In addition to being available from many FTP sites, ISO images can be downloaded via the BitTorrent tracker, or for users of earlier FreeBSD releases, FreeBSD Update can be used to perform a binary upgrade."
Black Hole Blasts Neighbor Galaxy with Deadly Jet 222
butterwise writes to mention that astronomers have, for the first time, witnessed a super-massive black hole hitting a nearby galaxy with a "death-star-like" beam of energy. The story also has a video with simulations, pictures, and explanations. "The 'death star galaxy,' as NASA astronomers called it, could obliterate the atmospheres of planets but also trigger the birth of stars in the wake of its destructive beam. Fortunately, the cosmic violence is a safe distance from our own neck of the cosmos."
The Transistor's 60th Birthday 185
Apple Acolyte sends in a Forbes piece noting the 60th birthday of the transistor on Dec, 16. For the occasion the AP provides the obligatory Moore's-Law-is-ending, no-it-isn't article. From Forbes: "Sixty years ago, on Dec. 16, 1947, three physicists at Bell Laboratories in Murray Hill, N.J., built the world's first transistor. William Shockley, John Bardeen and William Brattain had been looking for a semiconductor amplifier to take the place of the vacuum tubes that made radios and other electronics so impossibly bulky, hot and power hungry."
Mars Rover Technology Used to Make Better Maps 49
Cal writes "An article on the O'Reilly Radar site discusses a new street mapping technology by a company in Berkeley called earthmine. They are using technology developed by the Jet Propulsion Lab for the Mars Exploration Rover missions for reconstructing three-dimensional data of the street-scape. 'The licensed software and algorithms are used to create a 3D representation of the local terrain, allowing autonomous routing of the MERs through the Martian environment. earthmine has combined this JPL technology with its unique, capture hardware and web delivery technology to deliver 3D data with unprecedented density and accuracy.'"
Toshiba To Launch "Super Charge" Batteries 202
ozgood writes in to let us know about Toshiba's announcement that it has developed a new type of rechargeable battery dubbed the Super Charge ion Battery, or SCiB. Toshiba claims the new battery will mainly target the industrial market, though they hint the technology may eventually find a home in electric vehicles. The SCiB can recharge to 90% of total capacity in under five minutes, and has a life span of over 10 years. "Toshiba also says the battery has excellent safety with the new negative electrode material having a high level of thermal stability and a high flash point. The battery is also said to be structurally resistant to internal short-circuiting and thermal runaway."
Switching Hospital Systems to Linux 305
jcatcw writes "Health care software vendor McKesson Provider Technologies is focusing on ways to cut IT costs for customers, including hospitals and medical offices. The cure is moving many of McKesson's medical software applications to Linux, which can then be used on less expensive commodity hardware instead of expensive mainframes. A deal with Red Hat allows McKesson to offer its software in a top-to-bottom package for mission-critical hospital IT systems."
