Global warming unequivocal in its advance, says NCAA expert
Global warming is unequivocal in its advance and will lead to more record-setting temperatures, says Warren Washington, a senior scientist at the National Center for Atmospheric Research; in a talk at Sandia Lab, Washington presented graph after graph showing how various atmospheric processes have combined to create stronger rainfall near the equator and more intense droughts in the subtropics, as well as sea-level rises and increased storm surges

Predictions by climate models are flawed, says MIT meteorology expert
Massachusetts Institute of Technology professor Richard Lindzen, a global warming skeptic, says that too much is being made of climate change by researchers seeking government funding; he said their data and their methods did not support their claims; for thirty years, climate scientists have been “locked into a simple-minded identification of climate with greenhouse-gas level. That climate should be the function of a single parameter (like CO2) has always seemed implausible. Yet an obsessive focus on such an obvious oversimplification has likely set back progress by decades,” Lindzen said

A device used to measure nuclear weapons effects is now used for rocket propulsion system
Can a device formerly used to test nuclear weapons effects find a new life in rocket propulsion research? That is the question in which researchers seek an answer; when assembled, the device will tip the scales at nearly fifty tons, and will be “one of the largest, most powerful pulse power systems in the academic world,” according to one researcher

Researchers say spoofed GPS signals can be countered
From cars to commercial airplanes to military drones, global positioning system (GPS) technology is everywhere — and researchers have known for years that it can be hacked, or as they call it, “spoofed”; the best defense, they say, is to create countermeasures that unscrupulous GPS spoofers can not deceive

Game lets players try their hand at computer security
A new game — Control-Alt-Hack — gives teenage and young-adult players a taste of what it means to be a computer-security professional defending against an ever-expanding range of digital threats; the game’s creators will present it this week in Las Vegas at Black Hat 2012; educators in the continental United States can apply to get a free copy of the game while supplies last; it is scheduled to go on sale in the fall for a retail price of about $30

Pulling CO2 from air feasible, if still costly, way to curb global warming
Emerging techniques to pull carbon dioxide from the air and store it away to stabilize the climate may become increasingly important as the planet tips into a state of potentially dangerous warming; lower-cost technology is a stumbling block so far

New U.S. biodedfense R&D network launched
On Monday, Texas A&M System dedicated a new research center which is part of a national network of centers aiming to develop strategies and products to counter bioterrorism, chemical and radiological attacks on the United States, and better strategies to deal with pandemics; the network will have facilities in Texas, Maryland, and North Carolina; the Texas dedication is the culmination of a Manhattan Project-like program for biological countermeasures, launched in 2004 by the Department of Health and Human Services; the research network aims to develop “rapid, nimble and flexible approaches” to vaccine and therapy development, and train the next generation of professionals to sustain U.S. capabilities in these areas

Temperature rise, CO2 follow each other closely
The greatest climate change the world has seen in the last 100,000 years was the transition from the ice age to the warm interglacial period; new research indicates that, contrary to previous opinion, the rise in temperature and the rise in the atmospheric CO2 follow each other closely in terms of time

Selfish-herd theory confirmed
Many animals spend time together in large groups not because they enjoy each other’s company, but rather because it lowers their own chances of being eaten should an uninvited guest arrive on the scene — or so the theory goes; now, researchers who have strapped GPS-enabled backpacks to flocking sheep and a herding dog provide some of the first hard evidence that this “selfish herd theory” is true
