Jetman Attempts Intercontinental Flight 140

Posted by samzenpus
from the a-jetwing-and-a-prayer dept.
Last year we ran the story of Yves Rossy and his DIY jetwings. Yves spent $190,000 and countless hours building a set of jet-powered wings which he used to cross the English Channel. Rossy's next goal is to cross the Strait of Gibraltar, from Tangier in Morocco and Tarifa on the southwestern tip of Spain. From the article: "Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth." Update 18:57 GMT: mytrip writes: "Yves Rossy took off from Tangiers but five minutes into an expected 15-minute flight he was obliged to ditch into the wind-swept waters."

Scientists Say a Dirty Child Is a Healthy Child 331

Researchers from the School of Medicine at the University of California have shown that the more germs a child is exposed to, the better their immune system in later life. Their study found that keeping a child's skin too clean impaired the skin's ability to heal itself. From the article: "'These germs are actually good for us,' said Professor Richard Gallo, who led the research. Common bacterial species, known as staphylococci, which can cause inflammation when under the skin, are 'good bacteria' when on the surface, where they can reduce inflammation."

Many marine animals avoid the build-up of drag-inducing barnacles through secreting oily residues from their pores or through the nano-molecular arrangement of their skin. Sailors regularly defoul their hulls, remove the barnacles, at dry-dock, which requires them to reduce the amount of time they have at sea. Some synthetic chemicals in paints have been used to prevent barnacle build-up but have been found to be toxic to marine animals and thus outlawed by several nations. Now, engineers are trying to replicate the skin of marine animals to produce a slippery hull to which marine bacteria cannot attach, saving fuel costs and improving speeds:

Designing ships to exude slime from their hulls could cut their fuel consumption by up to 20 per cent. The slime would form a gelatinous skin that continually sloughs off, taking with it the barnacles and other marine life forms that cause energy-sapping drag as they accumulate on the ships' underside.

Data Storage

+ - Best setup for a cheap, quiet, cool file server?

Greg_D writes: I have mostly sworn off building my own computer systems over the years because I feel I generally have had trouble with them running at a cool temperature. Not that they would overheat, just that they tend to pump out so much heat that it typically warms my office where I keep a television and a game console to the point where it gets unbearable in the summer time. I am looking for a setup for a system that is relatively cheap, low power consumption, low heat production, and the ability to handle multiple terrabytes of RAID storage to be hooked up to a router for my personal file server. Graphic are not especially important, although it would be nice to be able to run a video out to the television to watch online or downloaded media, and perhaps with the possibility of installing a blue-ray player once they come down in price. This isn't really a media center PC in the sense that I don't really care about recording any video, but I might want to play Netflix shows on the box. Can I invest in an Atom processor and onboard graphics, or do I need something a bit more substantial?
