Killer Whales Don't Usually Kill People

From Live Science:

News of a trainer being killed by a killer whale at SeaWorld Orlando today doesn't change the fact that these giants, while deadly predators, do not kill humans at sea.

"They have never killed a human in the wild," said Nancy Black, a marine biologist with Monterey Bay Whale Watch. That's mostly because, unlike sharks, killer whales don't frequent near-shore areas where people swim. (Even shark attacks on humans are generally accidental, experts say, with sharks mistaking humans for seals or other typical food.)

From Discovery News:

By working out in intense intervals, people can squeeze a week's worth of exercise into less than an hour.

THE GIST:

* Intense exercise sessions can help squeeze a whole week's workout into less than an hour.
* Experts say interval training is twice as effective as normal exercise.
* Researchers are trying to learn now if older and less fit people can handle this type of exercise.

People who complain they have no time to exercise may soon need another excuse.

Under Fire, Administrator Defends NASA’s New Direction

From The New York Times:

WASHINGTON — Maj. Gen. Charles F. Bolden Jr., the administrator of the National Aeronautics and Space Administration, faced skeptical, sometimes hostile questioning on Thursday from members of a key House committee who said they opposed the Obama administration’s plans to revamp the nation’s human spaceflight program.

General Bolden told the Committee on Science and Technology that the president’s $19 billion budget proposal for NASA — which would cancel the agency’s program to send astronauts back to the Moon, invest in new space technologies and turn to commercial companies for transportation beyond low-Earth orbit — would provide a “more affordable and more sustainable” approach to space exploration.

Space Pioneer Burt Rutan Blasts NASA Plan

From The Wall Street Journal:

Commercial space pioneer Burt Rutan has sharply criticized Obama administration proposals to outsource key portions of NASA's manned space program to private firms.

The White House wants NASA to use outside firms to develop and operate new rockets and spacecraft that would transport astronauts into orbit and beyond, functions that had previously been considered a core function of the agency. Mr. Rutan, a veteran aerospace designer and entrepreneur, in a letter addressed to lawmakers on Capitol Hill, says he is "fearful that the commercial guys will fail" to deliver on the promises to get beyond low earth orbit, and that the policy risks setting back the nation's space program.

Physicists Discover Odd Fluctuating Magnetic Waves

Brown University physicist Vesna Mitrovic and colleagues have discovered magnetic waves that fluctuate when exposed to certain conditions in a superconducting material. The find may help scientists understand more fully the relationship between magnetism and superconductivity. (Credit: Lauren Brennan/Brown University)

From Science Daily:

Science Daily (Feb. 24, 2010) — At the quantum level, the forces of magnetism and superconductivity exist in an uneasy relationship. Superconducting materials repel a magnetic field, so to create a superconducting current, the magnetic forces must be strong enough to overcome the natural repulsion and penetrate the body of the superconductor. But there's a limit: Apply too much magnetic force, and the superconductor's capability is destroyed.

Larger Threat Is Seen In Google Case

From The New York Times:

ROME — Three Google executives were convicted of violating Italian privacy laws on Wednesday, the first case to hold the company’s executives criminally responsible for the content posted on its system.

The verdict, though subject to appeal, could have sweeping implications worldwide for Internet freedom: It suggests that Google is not simply a tool for its users, as it contends, but is effectively no different from any other media company, like newspapers or television, that provides content and could be regulated.

Is The Bloom Energy Server Cost, Scale Prohibitive?

From Channel Web:

The unveiling of the Bloom Energy Server, a power generating device that lets home and business users meet their own electricity needs with clean energy while taking them off of the power grid, was met with great fanfare this week.

But solution providers say the $700,000 to $800,000 price tag along with its ability to generate 100 kilowatts of electricity could make it a difficult sell.

"The price point I believe is going to be the difficult thing," said Darryl Parker, CEO of Parker Web Services, a North Carolina solution provider.

America’s Wind Energy Potential Triples In New Estimate

From Wired Science:

The amount of wind power that theoretically could be generated in the United States tripled in the newest assessment of the nation’s wind resources.

Current wind technology deployed in nonenvironmentally protected areas could generate 37,000,000 gigawatt-hours of electricity per year, according to the new analysis conducted by the National Renewable Energy Laboratory and consulting firm AWS Truewind. The last comprehensive estimate came out in 1993, when Pacific Northwest National Laboratory pegged the wind energy potential of the United States at 10,777,000 gigawatt-hours.

The Great Filament

From Watts Up With That?

The Solar and Heliospheric Observatory (SOHO) is tracking an enormous magnetic filament on the sun. It stretches more than one million kilometers from end to end, which makes it an easy target for backyard solar telescopes. For the seventh day in a row, an enormous magnetic filament is hanging suspended above the surface of the sun’s southern hemisphere. The Solar and Heliospheric Observatory (SOHO) has a great view. How long can it last? Solar filaments are unpredictable. If this one collapses and hits the stellar surface, the impact could produce a powerful Hyder flare.
