DIY Space Photography 106

Four Spanish teenagers sent a camera-operated weather balloon into the stratosphere. The boys built the electronic sensor components from scratch. Gerard Marull Paretas, Sergi Saballs Vila, Marta Gasull Morcillo and Jaume Puigmiquel Casamort attached a £56 camera to a heavy duty £43 latex balloon, and sent their science project 20-miles above the Earth. Team leader Gerard Marull, 18, said, "We were overwhelmed at our results, especially the photographs, to send our handmade craft to the edge of space is incredible."

Linux Foundation Asks Who Says "I'm Linux" Best 459

An anonymous reader writes "Everyone has seen Apple's clever 'I'm a Mac' ads, and Microsoft's attempted responses, first with Jerry Seinfeld, and next with 'I'm a PC.' The Linux Foundation tries to fire back with its community-generated 'We're Linux' video contest: all of the eligible videos have now been submitted and are ready to be voted on. Thankfully, the quality of Linux is much higher than the quality of some of these entries: entries range from the hilarious but inappropriate, to the well-made but creepy, to the 'I'm sure it sounded good in your head.' Thankfully, there are one or two that could actually be real commercials."
Encryption

The Emerging Science of DNA Cryptography 46

KentuckyFC writes "Since the mid 90s, researchers have been using DNA to carry out massively parallel calculations which threaten encryption schemes such as DES. Now one researcher says that if DNA can be used to attack encryption schemes, it can also protect data too. His idea is to exploit the way information is processed inside a cell to encrypt it. The information that DNA holds is processed in two stages in a cell. In the first stage, called transcription, a DNA segment that constitutes a gene is converted into messenger RNA (mRNA) which floats out of the nucleus and into the body of the cell. Crucially, this happens only after the noncoding parts of the gene have been removed and the remaining sequences spliced back together." (More below.)
