Science has finally gone and done something useful for a change by inventing a mouthwash that they say can completely eliminate the bacteria responsible for tooth decay. Refined sugar, you and me have a brand new (and sparkly white) future to look forward to.
Project Gemini through the eyes of the astronauts, part 1

On every mission of NASA's Gemini program in the mid 1960s, the astronauts took Hasselblad 500c cameras with 70mm film and Zeiss 60mm lenses along with them. You've almost certainly seen a few of the more famous pictures that were taken on Gemini, but Arizona State has recently scanned in all of the original negatives (nearly 3,000 of them) and put them online in a high-resolution archive for the first time. We've looked through every single ...
What Recession? Razer’s $2800 Blade Gaming Laptop Sells Out In 30 Minutes

For months we’ve been waiting on Razer’s Blade notebook , a $2800, 17-inch beast that we weren’t sure whether to laud or mock. It’s just that it’s kind of a strange thing to see making a big debut when people are more cautious than usual with their money, and PC gaming (as ever) is being declared dead. But after our hands-on at CES , we were convinced that it was at the very least impressive and well-built, and apparently enough other people thought so that Razer sold ...

Canada might not have much of a space program, but that could change once a couple of 17 year old schoolboys get into the workforce. Mathew Ho and Asad Muhammad managed to send a Lego Minifig out to the edge of space, and they did it with a budget of just $400.
Kindle Sales Growing Faster Than The Nook’s

Barnes & Noble may be challenging Amazon’s dominance of the e-book world, but Kindle sales are still growing faster than the Nook’s — at least if you connect the dots between some of the numbers included in a recently-published article by The New York Times . The article doesn’t hide the fact that Amazon has the vast majority of marketshare, with Barnes & Noble saying it has 27 percent of the market, compared to Amazon’s share of “at least 60 percent.” At the same time, the article ...
Russian Soyuz grounded again, SpaceX Dragon may be next to ISS

Well, this is no good: testing has revealed cracks in the Soyuz landing capsule that Russia was supposed to launch to the ISS, rendering it decidedly un-spaceworthy. The launch date has been rescheduled until April or May, meaning that SpaceX's Dragon capsule might be the next arrival at the ISS.
Dirty Money

The New York Times has published a long article on Foxconn which, while it doesn’t provide much in the way of new information, does act as a sobering reminder of just how companies like Apple can make so very much money. When our own John Biggs visited Foxconn , he focused on the company itself, its scale, its intentions. When I wrote about Apple’s suppliers failing to meet environmental standards , it was more about the laxity of regulators within China. Today’s NYT piece depicts Apple as ...
