Impact of land use activity in the Amazon basin evaluated
Portions of the Amazon basin are experiencing a transition in energy and water cycles. Evidence suggests that the Amazon may also be transitioning from a net carbon sink to a net source. This research shows that although the Amazon is resilient to individual disturbances, such as drought, multiple disturbances override this, increasing the vulnerability of forest ecosystems to degradation. This review provides a framework for understanding the associations between natural variability and drivers of change.

23:36A bizarre creature that lived in the ocean more than 500 million years ago has emerged from the famous Middle Cambrian Burgess Shale in the Canadian Rockies. Officially named Siphusauctum gregarium, fossils reveal a tulip-shaped creature that is about the length of a dinner knife (approximately 20 centimeters or eight inches) and has a unique filter feeding system.

LightSquared Charges that U.S. Testing Was 'Rigged'
A company planning a high-speed wireless service, with coverage for as many as 260 million U.S. customers, is charging that a governmental test of possible GPS interference from its transmissions was "rigged."On Wednesday, Reston, Va.-based LightSquared said in a statement that the test, conducted by the Space-Based Positioning, Navigation, and Timing Executive Committee (PNT EXCOM), was manipulated by "manufacturers of GPS receivers and government end users to produce bogus results."
LightSquared is looking to provide what it describes as the first wholesale-only integrated wireless broadband and satellite network in the U.S. The company asked the National Telecommunication and Information Administration (NTIA), which oversaw the testing, to "objectively re-evaluate" the results, and to evaluate proposals the company has offered to mitigate interference. It has also requested that the NTIA and the Federal Communications Commission conduct a second round of tests at an independent lab.
'Cherry-Picked' GPS Devices Company executives cited several ways in which, they said, the tests were manipulated. First, they contend that the test was conducted in a non-transparent, secretive fashion. As an example, LightSquared said the tested GPS devices were "cherry-picked" without independent oversight or input from LightSquared.
The company also contended that testing protocol was "deliberately" focused on "obsolete and niche market devices that were least able to withstand potential interference," including some that had been discontinued or that had poor or no filters. These devices represented no more than 1 percent of the market, according to LightSquared, and it noted that the one mass market device that was said to have failed the PNT EXCOM test, had passed a previous test by the Technical Working Group.
Finally, LightSquared said the testing standard was "an extremely conservative definition of failure," one dB of interference. However, the company said, "independent experts" agree that one dB can only be measured in the lab...

23:11IT will be charged with doing more with less in 2012. That's because budgets are largely flat, increasing a mere half percent overall -- and actually declining in North America and Europe. So says a global survey of CIOs by Gartner. The bright spot, though, is Business Intelligence, or BI.
Mark McDonald, group vice president for Gartner Executive Programs and a Gartner Fellow, says that just because technology's role in the enterprise is increasing does not mean that the role of the IT organization is increasing.
"CIOs concentrating on IT as a force of operational automation, integration and control are losing ground to executives who see technology as a business amplifier and source of innovation," McDonald said. "Effective leaders use technology, which includes IT, to strengthen the customer experience and eliminate costly internal distortions. They are using technology to 'amplify' the enterprise."
Business Intelligence Wins Budget As McDonald sees it, business strategies call for a combination of growth and operational efficiency -- and effective leaders see customers as the key factor in both of these strategic components, with the customer experience their focal point in reconciling potentially conflicting goals.
"Present economic conditions may tempt CIOs to force IT back into cost-cutting mode, but senior executives expect technology -- and this includes IT -- to address the tough challenges by amplifying enterprise strategies and operations," McDonald said.
One areas CIOs may not cut costs is in the areas of analytics/business intelligence, mobility, cloud and social technologies. In fact, BI and analytics was the top-ranked technology for 2012, Gartner reports, as CIOs are combining analytics with other technologies to create new capabilities. For example, analytics plus supply chain for process management and improvement, analytics plus mobility for field sales and operations, and analytics plus social networking for customer engagement and acquisition.
"BI has importance to line management and...

Amazon Basin shifting to carbon emitter
The Amazon Basin, traditionally considered a bulwark against global warming, may be becoming a net contributor of carbon dioxide (CO2) as a result of deforestation, researchers said on Wednesday. -
22:24People living along the coast of Peru were eating popcorn 1,000 years earlier than previously reported and before ceramic pottery was used there, according to a new paper in the Proceedings of the National Academy of Sciences co-authored by Dolores Piperno, curator of New World archaeology at the Smithsonian's National Museum of Natural History and emeritus staff scientist at the Smithsonian Tropical Research Institute.

22:24Everyone knows exercise is good for you. We’re told time spent on the treadmill can reduce our risk of diabetes, cancer, and cardiovascular disorders. But exactly how exercise provides this protection is a bit of a mystery. A new study finds that exercise prompts cells to break down unwanted proteins and other cellular junk to produce more energy. The process, called autophagy, may explain how exercise fends off metabolic disorders like diabetes and protects against other diseases.

22:24Investigators at the Massachusetts General Hospital (MGH) Cancer Center have identified a new genetic signature associated with bile duct cancer, a usually deadly tumor for which effective treatment currently is limited. Their report, which has been published online in The Oncologist, finds that growth-enhancing mutations in two related genes may account for nearly a quarter of bile duct tumors arising within the liver, presenting the possibility that drugs targeting this mutation could represent a new strategy to control tumor growth.

22:24(PhysOrg.com) -- Over a period of 12 years, Andrei Chikatilo murdered at least 53 people before being arrested in Rostov, Russia, in 1990. While Chikatilo’s killings, mainly of women and children, may have been senseless, a new study has found some sense in the distribution of intervals between the murders, which closely follows a power law. The researchers propose that the murder activity can be explained by a model describing neuronal firing in the brain, very similar to the model that describes the distribution of intervals between epileptic seizures.
