Thank you for saying this. It's all too true. Oh, and I'm a dude, by the way. Not that it should matter.
Submission + - NASA plans for Earth Impactors 1
TopSpin writes: Flight International reports that scientists at the Marshall Space Flight Center have developed designs for an Aries V launched array of asteroid interceptors wielding B83 nuclear warheads. The hypothetical mission for these designs is based on an Apophis sized Earth impactor 2-5 years out. According to NASA, "Nuclear standoff explosions are assessed to be 10-100 times more effective [at deflection] than the non-nuclear alternatives analyzed in this study (pdf)."
Submission + - Untapped Energy Below Us (yahoo.com) 1
EskimoJoe writes: "BASEL, Switzerland — When tremors started cracking walls and bathroom tiles in this Swiss city on the Rhine, the engineers knew they had a problem.
"The glass vases on the shelf rattled, and there was a loud bang," Catherine Wueest, a teashop owner, recalls. "I thought a truck had crashed into the building."
But the 3.4 magnitude tremor on the evening of Dec. 8 was no ordinary act of nature: It had been accidentally triggered by engineers drilling deep into the Earth's crust to tap its inner heat and thus break new ground — literally — in the world's search for new sources of energy.
On paper, the Basel project looks fairly straightforward: Drill down, shoot cold water into the shaft and bring it up again superheated and capable of generating enough power through a steam turbine to meet the electricity needs of 10,000 households, and heat 2,700 homes.
Scientists say this geothermal energy, clean, quiet and virtually inexhaustible, could fill the world's annual needs 250,000 times over with nearly zero impact on the climate or the environment.
A study released this year by the Massachusetts Institute of Technology said if 40 percent of the heat under the United States could be tapped, it would meet demand 56,000 times over. It said an investment of $800 million to $1 billion could produce more than 100 gigawatts of electricity by 2050, equaling the combined output of all 104 nuclear power plants in the U.S."
Submission + - First Armed Robots on Patrol in Iraq
An anonymous reader writes: Robots have been roaming Iraq, since shortly after the war began. Now, for the first time — the first time in any warzone — the 'bots are carrying guns. The SWORDS robots, armed with M249 machine guns, "haven't fired their weapons yet," an Army official says. "But that'll be happening soon." The machines have actually been ready to a while, but safety concerns kept 'em off the battlefield. Now, the robots have kill switches, so "now we can kill the unit if it goes crazy," according to the Army. I feel safer already.
Submission + - Forensics Expert says Al-Qaeda Images Altered
WerewolfOfVulcan writes: Wired reports that researcher Neal Krawetz revealed some veeeeeery interesting things about the Al-Qaeda images that our government loves to show off.
From the article: "Krawetz was also able to determine that the writing on the banner behind al-Zawahiri's head was added to the image afterward. In the second picture above showing the results of the error level analysis, the light clusters on the image indicate areas of the image that were added or changed. The subtitles and logos in the upper right and lower left corners (IntelCenter is an organization that monitors terrorist activity and As-Sahab is the video production branch of al Qaeda) were all added at the same time, while the banner writing was added at a different time, likely around the same time that al-Zawahiri was added, Krawetz says." Why would Al-Qaeda add an IntelCenter logo to their video? Why would IntelCenter add an Al-Qaeda logo? Methinks we have bigger fish to fry than Gonzo and his fired attorneys... }:-) The article contains links to Krawetz's presentation and the source code he used to analyze the photos.

Submission + - New Theory Explains Periodic Mass Extinctions
i_like_spam writes: The theory that the dinosaurs were wiped out by an asteroid impact, the K-T extinction, is well known and supported by fossil and geological evidence. Asteroid impact theory does not apply to the other fluctuations in biodiversity, however, which follow an approximate 62 million-year cycle. As reported in Science news, a new theory seems to explain periodic mass extinctions. The new theory found that oscillations in the Sun relative to the plane of the Milky Way correlate with changes in biodiversity on Earth. The researchers suggest that an increase in the exposure of Earth to extragalatic cosmic rays causes mass extinctions. Here is the original paper describing the finding.

It isn't easy being the parent of a six-year-old. However, it's a pretty small price to pay for having somebody around the house who understands computers.
