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.

Chinese Scientists Would Feel "Blind" If Google Pulled Out


From Popular Science:

Scientists don't want to see Google go bai bai.

Most Chinese citizens may still rely on homegrown Baidu for their Internet search needs, but Google's threatened pullout apparently worries the vast majority of Chinese scientists surveyed by the journal Nature. "If I lose Google, it will [be] just like a man without his eyes," one respondent said.

New All-In-One Space Weather Tool From NASA


From Watts Up With That?:

The press release doesn’t contain any pictures, and really doesn’t do this new web tool justice, so I’ve added some screencaps. In a nutshell, the new iSWA site lets you arrange graphical packages of solar images and plots oncsreen for simultaneous evaluation. Stuff that had been scattered over several solar related websites is now in one interface. Pretty cool. – Anthony

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.

From New Scientist:

WI-FI as we know it is reaching the limits of its usefulness. It just can't keep up with our appetite for services, such as new video formats, that gobble up bandwidth. So what's next in the world of blisteringly fast home-based wireless technologies?

For clues to where Wi-Fi is going, it helps to delve into the soup of standards that will shape the future of wireless communications.

Larger Threat Is Seen In Google Case

Bill Echikson, a spokesman for Google, called a judge's ruling against executives “astonishing.” Paolo Bona/Reuters

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.

From The Telegraph:

One in 10 teenagers has been a victim of cyberbullies, according to university research.

The internet means that they can be targeted round-the-clock, researchers warned.

Experts claim that cyberbullying can be more damaging than conventional teasing because perpetrators can remain anonymous and therefore make more hurtful claims.

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.

Amazing Facts And Figures About The Evolution Of Hard Disk Drives

Above: Three decades of shrinkage.

From Pingdom:

It took 51 years before hard disk drives reached the size of 1 TB (terabyte, i.e. 1,000 GB). This happened in 2007. In 2009, the first hard drive with 2 TB of storage arrived. So while it took 51 years to reach the first terabyte, it took just two years to reach the second.

This article looks back at how hard disk drives have evolved since they first burst onto the scene in 1956. We’ll examine the radical changes over time for three different aspects of HDDs: Size, storage space, and price.

From Science Daily:

Science Daily (Feb. 25, 2010) — In ongoing work to identify how genes interact with social environments to impact human health, UCLA researchers have discovered what they describe as a biochemical link between misery and death. In addition, they found a specific genetic variation in some individuals that seems to disconnect that link, rendering them more biologically resilient in the face of adversity.

Brain's 'Fairness' Spot Found

Humans tend not to like unequal situations, and now scientists have found the first evidence that this behavior is reflected in the human brain. Here, an fMRI scan of a human brain showing activity in the striatum and prefrontal cortex, regions of the brain thought to be involved in how people evaluate rewards. Credit: Elizabeth Tricomi, Rutgers University.

From Live Science:

At some point in our lives, we've all cried "It's not fair!" In fact, it's human nature for us to dislike unequal situations, and we often try to avoid or remedy them. Now, scientists have identified the first evidence of this behavior's neurological underpinnings in the human brain.

The results show that the brain's reward center responds to unequal situations involving money in a way that indicates people prefer a level playing field, and may suggest why we care about the circumstances of others in the first place.
