'Mommy robot' can build and test its own babies
A University of Cambridge team of researchers has created a "mother robot" capable of giving birth to -- or more correctly, building its own -- baby cube-bots. The team conducted five rounds of experiments, wherein it assembled 10 pint-sized machine children per generation with a motor and one to five plastic cubes. It then observed how fast they moved, as well as how far they got, all without human intervention. Momma bot left the fastest ones untouched, while "mutation and crossover were introduced" in the slower robo-kids for the next generation. By the time it got to the last batch, the small machines moved twice as fast as the fastest first-gen baby bots.
Headphone-wearing pedestrian injuries triple as audiophiles stop noticing onrushing trains
The number of pedestrians injured or killed while wearing headphones has tripled in the last six years: 16 oblivious PMP users were offed in 2004, the number rising to 47 for last year. The research, carried out by Dr Richard Lichenstein at the University of Maryland found that headphone wearers became "inattentionally blind" to dangers such as passing cars and on-rushing trains. That's not us being flip either: 55 percent of the incidents involved locomotives. The majority of victims were male (68 percent) and under the age of 30 (67 percent): which puts your average Engadget reader in the center of the danger zone -- take it from us guys: sometimes it's better to press pause, "Baby, baby" will still be there when you've crossed the railway.
Toshiba Natural Selection laptops get celebrity paintjobs, good causes
Alright, we're not too happy with the Natural Selection moniker implying that being a celebrity is somehow a marker of evolutionary prowess, but we'll forgive Toshiba this one time. The Japanese company has recruited a quartet of famous folks to help promote its wares with limited edition laptops painted to their specifications. Aerosmith guitar legend Joe Perry, the no less mythical Rainn Wilson, Pittsburgh Steeler Hines Ward and his coach Mike... oh wait, that's Omar Epps, have put their own personal stamps on a selection of Toshiba's latest 505 laptop models from the A, P, M, and Qosmio X series. These will be auctioned off on eBay starting this Friday, with all proceeds going to charity. Any more questions before you start the bidding? No? Good. %Gallery-78904%
