Such is the claim of University of Colorado researcher Jun Ye:

"This technique can give a broad picture of many different molecules in the breath all at once," Jun Ye, who led the research at the University of Colorado, said in a statement.
Ye's team at a joint institute of the National Institute of Standards and Technology and the university developed a new technique, called cavity-enhanced direct optical frequency comb spectroscopy.
When animals and people breathe out, they exhale not only gases that are not needed, such as carbon dioxide, but also compounds that result from the metabolism of cells.
A link to the abstract for the original submission by Ye's team, as well as a PDF of the study, can be found here."

u-bend writes: "Apple has released new, higher capacity models of the iPhone and iPod Touch. The new iPhone boasts 16 GB of storage and is priced at $499.00 (the 8 GB model remains at #399.00), and the new iPod Touch has 32 GB, also priced at $499.00. Although the price is still pretty hefty, it indicates that the capacity/price ratio on these wireless flash-based players is starting to move in the right direction."

u-bend writes: "There's a story at Wired about a new magnetic brain stimulation technology that's expected to soon gain FDA approval. Much less invasive than electroconvulsive therapy, the device stimulates the cortex and associated blood vessels by being placed on the patient's head, in a procedure so mild that patients can get in their cars afterward and drive back to work: 'TMS works by creating an electromagnetic pulse that doesn't disturb the skull or scalp, but can reach two to three centimeters into the brain to stimulate the prefrontal cortex and paralimbic blood flow, increasing the serotonin output and the dopamine and norepinephrine functions.'
The question is, does it work through tinfoil hats as well?"

Submission + - EMI Agrees to Takeover

u-bend writes: "The International Herald Tribune is running a story about EMI's upcoming takeover by a private equity group. The article states that EMI's stock "soared" after the announcement. Even so, the company's stock finished the day at London's stock exchange at just USD 5.30, or 3.94 Euro, which was about an 8.5% increase.
From the article:
'EMI Group PLC, home to the Beatles and Coldplay, agreed to a 2.4 billion pound (US$4.7 billion; 3.5 billion) takeover by a private equity group on Monday, but the deal raised speculation of an all-out bidding war for the struggling music group.'
Anyone want to speculate what effect this will have on the recent DRM-free decision with Apple?"

Submission + - NASA Detects "California-sized" Antarctic

u-bend writes: "Discovery has an article about a massive melt detected in a region of Antarctica previously thought to be virtually impervious to such a climate shift.

From the article:
'A team of scientists from NASA's Jet Propulsion Laboratory in Pasadena, California, and the University of Colorado said new satellite imagery had revealed a vast expanse of snow melt in 2005 where it had previously been considered unlikely.

The NASA statement described the findings as "the most significant melt observed using satellites during the past three decades."'

Rather interesting in light of recent discussions about the pros and cons of global warming."

u-bend writes: "Discovery has an interesting little article about a super-ancient star right here in our galaxy. According to the article, the star could be almost as old as the universe itself.
From the article:
Known as HE1523-0901, the 13.2-billion-year-old star was born half a billion years after the universe exploded into existence, say astronomers.
That unprecedented birthdate was confirmed by using the European Southern Observatory's (ESO) Very Large Telescope to split the star's ultraviolet light into individual wavelengths — like a UV rainbow. In that rainbow, or spectrum, they were able to identify lines that show the presence of heavy elements like uranium and thorium."

Submission + - Using Sensors to Fight Poaching

u-bend writes: "In an attempt to combat elephant poaching in the Republic of Congo, a trailside metal detector system is being installed on commonly used poaching routes. If successful, it is hoped that that this method can be used in other poaching hot spots, such as Russia, the Galapagos Islands, and Costa Rica. Better not go camping with old fashioned metal tent pegs.
From the article:
'Endangered animals killed for their skins, meat or tusks may soon have a life-saving technology on their side. A metal-detecting sensor that can be buried alongside oft-used trails help identify weapons and alert authorities to potential poachers.'"

Submission + - Methane as the Next Interplanetary Fuel?

u-bend writes: "Discovery news has a quick read about the possibilities that methane has as a rocket fuel for future interplanetary exploration, since it's known to exist on other planets.

From the article:
"The trouble with exploring the solar system is that there just aren't any rocket fueling stations out there. That won't be the case if future planet-hopping astronauts are equipped with a new kind of rocket engine which burns two gases that are already in good supply on several other planets: methane and oxygen.""

From the article:
The brightest stellar explosion ever recorded may be a long-sought new type of supernova, according to observations by NASA's Chandra X-ray Observatory and ground-based optical telescopes. This discovery indicates that violent explosions of extremely massive stars were relatively common in the early universe, and that a similar explosion may be ready to go off in our own galaxy.
