Mathematicians at UCLA discovered the 45th known Mersenne prime with
almost 13 million digits. The discovery makes the group eligible for a
$100,000 prize, which was promised for discovering the first prime with
more than 10 million digits.
Nero has announced its LiquidTV software that turns
your Windows computer into a Tivo digital video recorder. Available in
October, LiquidTV lets people save high definition and standard def
shows onto computer hard drives. These shows can viewed later or
exported to Apple iPods or the Sony PSP. You can even burn the content
NASA today said that is Phoenix Mars Lander has detected snow falling
from Martian clouds and found more details about soil data that are
believed to hint to a liquid past. The organization also plans to
update journalists on a “significant anomaly” affecting its Hubble
Space Telescope, which will delay next month's space shuttle Atlantis'
Hubble servicing mission.
Aerial and satellite photography regularly helps
our troops fight on the battlefield, but the same technology is now
being used by cash-strapped counties to assess taxes. In Cape May
County, New Jersey, county tax assessors are using photos to look for
illegal additions to properties and to fine farmers for not farming
enough. The county says the photos are a fantastic tool, but some
people say the government has no business peeking into our backyards.
With the current state of our economy, it’s a no brainer that many of
us could use an extra $10 million. Here is one way to get your hand on
this amount: The Department of Energy is holding a competition that
envisions a new generation of light bulbs: The L Prize will reward an
individual or organization with a prize money of $10 million, who
creates a viable solid-state LED replacement for the standard 60 watt
incandescent bulb. A second prize will also be awarded for any company
creating a replacement for a PAR 38 halogen reflector lamp.
Sure the English Channel has been crossed before, but Yves Rossy is
the first person to do it with a rocket pack. The self-proclaimed
49-year-old “Fusion Man” jumped out of an airplane over Calais France
and covered 22 miles in 13 minutes while suspended on a composite
wing. Rossy rocketed at 120 MPH thanks to the help of four
kerosene-powered jet turbines affixed to the wing. He landed safely
near the famous White Cliffs of Dover in England.
Scientists at UC-Santa Barbara have engineered a new nano-construction process capable of assembling integrated circuits. Five companies helped fund the research, including giants Intel and IBM. A patent was also filed for their discovery. According to the researchers, this technology could be introduced into mainstream semiconductor manufacturing as early as 2011.
Inventors at Google have developed a novel concept to end the war of cell phone and wireless contracts. Their idea was awarded a patent yesterday and relates to per use bidding. Their patent is broad enough that it could apply to all wireless communications, including GSM, 3G, WiFi, WiMAX and the so-called "white space spectrum" which will be freed up once analog TV broadcasts are replaced with digital ones in 2009. "Bid before you use" is the model Google has patented. But will it work?
While many commercial ventures are searching for ways to improve efficiency in the dominant spin-torque model for Magnetoresistive-RAM (or MRAM), Japanese physicsts have stumbled upon an entirely new approach which uses less power, switches faster and is even easier to manufacture.
Researchers from the University of Lehigh conducted an experiment which
they belive indicates that people are more prone to lie in an email
than in traditional pen and paper communications. They claim that their
results show a more frequent and calculated abuse of the truth online
A team of scientists affiliated with MIT's Mechanical Engineering department have solved a 100-yr old engineering problem. In 1904, a German physicst named Ludwig Prandtl mathematically solved the problem of flow separation in fluids. His work did have limitations, however, namely that it only worked in two dimensions and the air flow had to be very steady. MIT's new model expands Prandtl's research into three dimensions and unsteady streams of air. Plus, it has the added bonus of being experimentally verified.
A new browser war unfolds as browser makers are
your desktop. Apple's new SquirrelFish Extreme engine promises a
two-fold speed increase and may put Safari 4 ahead of the pack.
However, given the breathtaking development pace of other browser
makers, it is far from certain that Safari 4 will be the fastest
browser on the planet when it debuts. Mozilla, Google and Microsoft as
well as smaller makers such as Opera are all working on more nimble and
The recently reported electrical problems in the LHC system will have a
greater impact than initially expected. A simple repair turned into a
two month shutdown, which in fact will turn into an outage that may
take at least six months. A restart of the collider is planned for
early spring, CERN said today.
Researcher teams led by Paul Kintner and Mark Psiaki at Cornell University have demonstrated that suitcase-sized transmitters could be employed to fool even commercial and military GPS units. By sending out "false authentic" signals in close proximity, those which mimic true GPS satellites, over time GPS receivers begin to accept the false signals as genuine and report improper position data to the user. Concerns over personal, commercial and military implications of the false data are the focus of the study.
