If you think the events of the post-Valentine’s day surprise of the Russian Meteor and 2012 DA14 near miss are one of a kind, think again. “We know there are 500,000 to 1 million asteroids the size of DA14 or larger. So far we have found fewer than 1% of that ‘cosmic hailstorm’ through which we sail in our yearly orbit around the Sun,” said the Association of Space Explorers… read more
Huh? Yep, you read it right.
We are bumping into a limit to increasing transistor speed, determined by the “electron transit time” — the time it takes an electron to travel, says Hong Koo Kim, a professor in the University of Pittsburgh’s Swanson School of Engineering.
It’s back to the vacuum, folks.
Kim explains: electrons traveling inside a semiconductor device frequently experience collisions or scattering… read more
Seeing Tim Burton’s Alice in Wonderland in IMAX 3-D (which continues as No. 1 in box office sales for the second weekend in a row), I thought that the Jabberwocky poem came from the original Alice in Wonderland, but it didn’t. It came from the sequel, Through the Looking Glass.
Recall that Lewis Carroll was a professor of mathematics at Oxford University before he was more well-known as the… read more
Radiation levels at Japan nuclear plant reach new highs: Leaked water sampled from one unit Sunday had 100,000 times the radioactivity of normal background levels…. airborne radioactivity in the unit 2 turbine building still remained so high — 1,000 millisieverts per hour — that a worker there would reach his yearly occupational exposure limit in 15 minutes. A dose of 4,000 to 5,000 millisieverts absorbed fairly rapidly will… read more

When we last visited our “RoboRoach” bionic cockroach, it was being remotely controlled by a mobile phone that triggered hallucinations of an invisible wall (for educational purposes only, mind you).
Now Dr. Alper Bozkurt, an assistant professor of electrical and computer engineering at North Carolina State University, and his team want to take it a step further. They plan to use their Madagascar hissing roaches (dubbed… read more

TechCrunch | Geo-location has come to this: After three weeks in review, Wheretheladies.at, a web app that aggregates Foursquare checkins by the female gender, is now available on the iPhone. The concept OF A BIG COMPASS POINTING YOU IN THE DIRECTION OF LADIES is so unprecedented that Apple actually called co-founder Jeff Hodsdon on his cellphone to ask about the app during the review process.
Co-founded by… read more

In What our civilization needs is a billion-year plan, posted on KurzweilAI September 23, 2012, Lt Col Peter Garretson calls for a long-term plan to assure humanity’s survival, “moving everyone and everything we value off Earth.”
He cites the coming big extinction events for planet Earth, including asteroid collisions, the Sun engulfing the Earth during its transformation to a red giant, and ultimately, the heat death of the Universe. Human… read more
