separsons writes "Scientists at the University of South Carolina recently transformed ordinary T-shirts into bulletproof armor. By splicing cotton with boron, the third hardest material on the planet, scientists created a shirt that was super elastic but also strong enough to deflect bullets. Xiaodong Li, lead researcher on the project, says the same tech may eventually be used to create lightweight, fuel-efficient cars and aircrafts."

Save the Planet, Eat Your Dog 942

R3d M3rcury writes "New Zealand's Dominion Post reports on a new book just released, Time to Eat the Dog: The real guide to sustainable living. In this book, they compare the environmental footprint of our housepets to other things that we own. Like that German Shepherd? It consumes more resources than two Toyota SUVs. Cats are a little less than a Volkswagen Golf. Two hamsters are about the same as a plasma TV. Their suggestions? Chickens, rabbits, and pigs. But only if you eat them."

The Numbers Stations Analyzed, Discussed 224

Posted by Zonk

GMontag wrote to mention a Washington Post article about the always-intriguing 'number' radio broadcasts. The numbers stations, as they are known, are 'hiding in plain sight' spycraft. Random digits broadcast at little-used frequencies are known to be intelligence agencies broadcasting their secrets in encrypted form. The Post article gives a nice run-down on the truth behind the transmissions, and touches a bit on the odd community that has grown fascinated by them. From the article: "On 6840 kHz, you may hear a voice reading groups of letters. That's a station nicknamed 'E10,' thought to be Israel's Mossad intelligence. Chris Smolinski runs SpyNumbers.com and the 'Spooks' e-mail list, where 'number stations' hobbyists log hundreds of shortwave messages transmitted every month. 'It's like a puzzle. They're mystery stations,' explained Smolinski, who has tracked the spy broadcasts for 30 years." This article made me recall a great All Things Considered story from a few years back about Akin Fernandez's 'Numbers' CD, a CD compilation of some of the most interesting strings of randomly read numbers reaching out across the airwaves.

Professor Comes Up With a Way to Divide by Zero 1090

54mc writes "The BBC reports that Dr. James Anderson, of the University of Reading, has finally conquered the problem of dividing by zero. His new number, which he calls "nullity" solves the 1200 year old problem that niether Newton nor Pythagoras could solve, the problem of zero to the zero power. Story features video (Real Player only) of Dr. Anderson explaining the "simple" concept."

Please someone contact them about putting out a firefox plugin. The spammers already have these things figured out (man in the middle attacks described further down in the comments) and I just want to get into my bank account and forums without having to take my glasses off, get about an inch away from the monitor and then have to try two or three times before getting one that's legible. Thankfully I got image-zoom on here so I haven't had to do the first two steps in a while. It's only a matter of time before they start using flash for these things though and then it's back to practically felching the monitor just to read the stupid things.

As an aside I handn't logged in yet to post and the person in the next cube over tells me the captchkacinno thing for this particular comment was "accuracy". Funny.

It is better to give than to lend, and it costs about the same.
