How to clean your clothes without water
by Cath in Basal Science (BS) Clarified
Photo credit: en.wikipedia.org Now that it’s the middle of a cold snowy winter, I’m looking forward to my annual summer camping trip. What can make camping even more enjoyable? Self-cleaning clothes. And I don’t mean jumping into the river with your clothes on, but simply just leaving them out in the sun. At least, that’s what [...]... Read more »

Copyright Talk: The RIAA Bites the Hand That Feeds
by DJ Busby in Astronasty
The perpetrators seem to be the RIAA's best friends. They just haven't have realized it yet. This should be motivation enough for the RIAA's to halt their lobbying, at least until they learn to read. In a business sense, for them to push the legislation of SOPA/PIPA seems ridiculous, given this context, doesn't it?... Read more »

A Glow-in-the-Dark Material that Lasts All Night and Longer
by Char in Basal Science (BS) Clarified
Remember those glow-in-the-dark stickers you had when you were a kid? They had to be “charged” in sunlight all day and would only glow for maybe 1 or 2 hours at the most. A research group at the University of Georgia has created a persistent phosphorescence material (i.e. glow-in-the-dark material) that has an afterglow (i.e. the glow in glow-in-the-dark) for more than 2 weeks after exposure to sunlight for only a few seconds to minutes. Moreover the afterglow emitted is designed so ........ Read more »

can we explore space with unmanned drones?
by Greg Fish in weird things
Drone patrols are nothing new. By now, they're fairly humdrum stuff come to think of it. But what about a drone patrol on an alien world, one that could potentially last for decades and bring us a constant stream of data on everything we wanted to know about the world in question? Well, that's the [...]... Read more »

A new year full of promises
by Marco Frasca in The Gauge Connection
We have left 2011 with a lot of exciting results from experiments. Neutrinos appear to move a bit faster than expected and Higgs provided some glimpses at CERN. Of course, this kind of Higgs appears somewhat boring at first being in the range of what Standard Model expected. But it is really too early to [...]... Read more »

The company is D-Wave, the quantum computing company. D-Wave's mission is to build a computer which will solve humanity's grandest challenges.D-Wave aims to develop the first quantum computer in the world, perhaps they already have. The advent of quantum computers would be a sea change in the world that would allow for breaking of c........ Read more »
