He says private drone use is more worrisome. That's because he's never adequately understood the need to restrain the state. Reuters As a Bush Administration lawyer, John Yoo employed flawed legal reasoning to facilitate torture and a view of executive power that would make the U.S. Constitution worthless if it were widely adopted. Despite his history of caring more about checks and balances when a Democrat is in the White House, he's been mostly comfortable with the excesses of the Obama era. And a recent item he published at Ricochet is yet another example of why he can't be trusted on questions concerning the federal government and the importance of restraining it to ...

The Department of Energy will spend $452 million—with a match from industry—over the next five years to guide two small modular reactor designs through the nuclear regulatory process by 2022. But cheap natural gas could freeze even small nuclear plants out of the energy market well beyond that date. DOE accepted bids through Monday for companies to participate in the Small Modular Reactor program. A number of reactor manufacturers submitted bids, including NuScale Power and a collaboration that includes Westinghouse and General Dynamic. “This would allow SMR technology to overcome the hurdle of NRC certification – the ‘gold standard’ of the ...

Silicene-based transistors could provide the next big leap in computer processor performance, new research from Europe suggests, and could surpass graphene after silicon reaches its performance peak. Silicon transistors are tiny switches that alternate between on and off states, representing either 0 or 1—the binary language of computers. Millions of these perform complex calculations in current processors, but computers with silicene transistors could operate hundreds of times faster. The researchers describe silicene as “the graphene equivalent for silicon” in their paper. Graphene is the most highly conductive material known, conducting electrons at much faster speeds ...

California's SpaceX has launched on a mission to re-supply the space station - the first cargo delivery to the orbiting outpost by a private company. The firm's Falcon rocket, topped by an unmanned Dragon freight capsule, lifted clear of its Florida pad at 03:44 EDT (07:44 GMT; 08:44 BST). The initial climb to an altitude some 340km above the Earth lasted a little under 10 minutes. Within moments of being ejected, Dragon opened its solar panels. It will take a couple of days to reach the station. The plan currently is for the vessel to demonstrate its guidance, control and communications systems on Thursday, at a distance of 2.5km from the International Space Station (ISS). ...
Why Women Choose Bad Boys. (It's science in action)

Women choose bad boys because their hormones make them, new research suggests. When ovulating a woman's hormones influence who she sees as good potential fathers, and they specifically pick sexier men over obviously more dependable men. "Previous research has shown in the week near ovulation women become attracted to sexy, rebellious and handsome men like George Clooney or James Bond," study researcher Kristina Durante, of The University of Texas at San Antonio, said in a statement. "But until now it was unclear why women would ever think it's wise to pursue long-term relationships with these kinds of men." The study was published today, May 14, in the Journal ...
Smart pedal tells driver when to ease off gas

Mercedes is developing a smart accelerator pedal which pushes back against drivers who threaten to ruin fuel efficiency by putting their foot down too hard. It promises to reduce fuel consumption by 10 percent, the firm said. The system uses an electric motor to generate resistance to a driver’s speed impulse, shifting the “bite point” of the pedal – and can be programmed to react to different degrees of pressure. There is even the option to make the accelerator vibrate against or tap the driver’s right foot to remind them to lay off the gas, news magazine Der Spiegel reported on Tuesday. The smart pedal would not give the driver such signals when pulling ...

Scientists in the United States have enabled a paralysed woman to lift a drink to her lips with a thought-controlled robotic arm, boosting hopes that tetraplegics may regain their independence. On April 12 last year, 58-year-old Cathy Hutchinson made history by using only her thoughts to get a robotic arm to grasp a flask of coffee on a table, lift it and hold it to her lips for a sip, the researchers said. Fourteen years earlier, a stroke had left her paralysed and unable to speak, making her completely dependent on a caregiver. "This was the first time in nearly 15 years that she has been able to pick up anything solely of her own volition -- and the smile on her face when she did ...

ScienceDaily (May 15, 2012) — Is Earth really a sort of giant living organism as the Gaia hypothesis predicts? A new discovery made at the University of Maryland may provide a key to answering this question. This key of sulfur could allow scientists to unlock heretofore hidden interactions between ocean organisms, atmosphere, and land -- interactions that might provide evidence supporting this famous theory. The Gaia hypothesis -- first articulated by James Lovelock and Lynn Margulis in the 1970s -- holds that Earth's physical and biological processes are inextricably connected to form a self-regulating, essentially sentient, system. One of the early predictions of this ...

myths & facts MYTH 1: Global temperatures are rising at a rapid, unprecedented rate. FACT: Accurate satellite, balloon and mountain top observations made over the last three decades have not shown any significant change in the long term rate of increase in global temperatures. Average ground station readings do show a mild warming of 0.6 to 0.8C over the last 100 years, which is well within the natural variations recorded in the last millennium. The ground station network suffers from an uneven distribution across the globe; the stations are preferentially located in growing urban and industrial areas ("heat islands"), which show substantially higher readings than ...
