New Xerox Products Promise Deep Cuts

(AP) -- Xerox Corp. introduced color printers and ink products Monday that it said will cut the price of color copying by two-thirds, sweeping away a major hurdle for customers seeking to enter the profitable and growing color market.

Spaceflight shown to alter ability of bacteria to cause disease

Space flight has been shown to have a profound impact on human physiology as the body adapts to zero gravity environments. Now, a new study led by researchers from the Biodesign Institute at Arizona State University has shown that the tiniest passengers flown in space—microbes—can be equally affected by space flight, making them more infectious pathogens.

Fluid theory confirmed by Foton spacecraft

In scientific research, there is great satisfaction when theoretical work is eventually supported by experimentation. Such was the case this week for a team of Italian and US scientists when they received preliminary confirmation of a 10-year-old theory from a fluid science experiment that is currently orbiting the Earth on the Foton-M3 spacecraft.

New imaging technique allows doctors to 'see' molecular activity

A new technique that will enable doctors to ‘see` things happening at the molecular level using standard imaging techniques has been developed by Oxford scientists. The technique has initially been directed towards multiple sclerosis, but long-term it has the potential to be used for a vast range of health problems. The findings are published by Nature Medicine on Monday 24 September.

New study suggests cause of debilitating skin condition

New findings from researchers at Wake Forest University Baptist Medical Center and colleagues suggest why some people with kidney failure can develop a rare tightening and swelling of the skin and other organs, including the lungs and heart.

Sizing cells up: Researchers pinpoint when a cell is ready to reproduce

For more than 100 years, scientists have tried to figure out the cell size problem: How does a cell know when it is big enough to divide? In research conducted in budding yeast (Saccharomyces cerevisiae), scientists at Rockefeller University have now identified the cellular event that marks the moment when a cell knows it is big enough to commit to cell division and spawn genetic replicas of...

Rare albino ratfish has eerie, silvery sheen

A ghostly, mutant ratfish caught off Whidbey Island in Washington state is the only completely albino fish ever seen by both the curator of the University of Washington's 7.2 million-specimen fish collection and a fish and wildlife biologist with more than 20 years of sampling fish in Puget Sound.

Gene Chip Data Improved Therapy In Some Patients With Incurable Cancer

Like many oncologists, Eric P. Lester, M.D., was faced with a dilemma: seven patients with advanced, incurable cancer; an arsenal of drugs that may or may not help them; and not enough solid proof about treatment efficacy to guide him. So, Dr. Lester devised what he called a "simple-minded experiment" that illustrates the promise of personalized medicine.

New Dinosaur Species Found In Montana

A dinosaur skeleton found 24 years ago near Choteau has finally been identified as a new species that links North American dinosaurs with Asian dinosaurs. The dinosaur would have weighed 30 to 40 pounds, walked on two feet and stood about three feet tall. The fossil came from sediment that's about 80 million years old.

Understanding The Neuron's Green Architecture

Being green is a lifestyle. Turns out, each of your neurons is deeply committed to that green lifestyle - and you didn't even know it. In just a thousandth of a second, a neuron can dump up to 5,000 molecules of its chemical messenger - a neurotransmitter - into the synapse, where it will trigger an impulse in a neighboring nerve cell. The neuron is a recycler par excellence when it comes to these...

First GPL Lawsuit Settling out of Court

In what must be one of the speediest copyright-infringement cases on record, Monsoon Multimedia has admitted to violating the GNU General Public License (GPL) and is entering settlement negotiations. On September 20, the Software Freedom Law Center (SFLC) announced it was suing Monsoon on behalf of the BusyBox project -- the first U.S. suit involving GPL version 2. The suit claimed that Monsoon...
