15-Year-Old Invents Algae-Powered Energy System 230

Mike writes "Signaling a bright future for sustainable energy, 15-year-old Javier Fernandez-Han has created a remarkable algae-powered energy system that is capable of producing food and fuel, treating waste, containing greenhouse gases, and releasing oxygen. Dubbed the VERSATILE system, the project recently netted him a $20,000 scholarship for winning this year's Invent Your World Challenge."

That is true, however Slashdot's advertisements are relatively noninvasive, and (somewhat) relivent. (dice anyone?) Digg conversely has those damn annoying auto playing flash and and blinking ads. If I had to view one sites advertisements over another, I would pick Slashdot's.

Europium's Superconductivity Demonstrated 103

gabrlknght writes "An old element just learned a new trick under pressure. When cooled and squeezed very hard, the soft metallic element europium turns into a superconductor, allowing electrons to flow unfettered by resistance, a study appearing May 13 in Physical Review Letters shows. The results make europium the 53rd of the 92 naturally occurring elements to possess superconductivity, which, if harnessed, could make for more efficient energy transfer."

Its not that its more humane to drown the pirates then to shoot them in the head, its a simple matter of insurance. The insurance price for a ship with guns is astronomically higher then one without. This is such a big deal that the merchant ships, such as the ones in this article, are looking for a way to protect themselves, and yet not pay the extra insurance costs.

The Taste Of Space 81

It turns out that space tastes like raspberries and not Tang or freeze-dried ice cream as one might suspect. Scientists at the Max Planck Institute for Radio Astronomy were searching for evidence of amino acids in space when they found ethyl formate, the chemical used in to make raspberry flavoring. The astronomers used the IRAM telescope in Spain to analyze electromagnetic radiation emitted by a hot and dense region of Sagittarius B2 that surrounds a newborn star. Astronomer Arnaud Belloche said, "It [ethyl formate] does happen to give raspberries their flavour, but there are many other molecules that are needed to make space raspberries."

Dell Adamo Review — Macho Outside, Sissy Inside 144

Odelia Lee writes with a full review of Dell's new Adamo slimtop over at Gizmodo. While it may have an sleek exterior there are definite gaps (both literal and figurative) in their engineering. "The Adamo is both a compliment and an insult to Dell engineering. It's possibly the most beautiful computer Dell has ever manufactured, but I'm not sure that Dell has caught up to competitors in either aesthetics or power. There have been lots of qualitative Adamo reviews out there, but we got the first of the units that will actually ship to customers, so it's time for real benchmarks. As it happens, performance is really what's at stake here."

Gecko-Inspired Dry Adhesive Set For Space 141

AndreV writes "Biomimetic adhesives aren't new, but a PhD graduate in British Columbia has developed a new method of creating microscopic, mushroom-like plastic structures in order to produce a dry adhesive that mimics the stickiness of gecko feet—and is prepping his glue-free innovation for outer space. A research group at his university, in collaboration with the European Space Agency, is engineering a spider-like, sticky-footed climbing robot destined to explore Mars, and it is also developing reusable attaching systems for astronauts to use where magnetic and suction systems generally fail. In the future, he says, single-use versions could be used in any number of medical applications as well as for replacements for everyday sticky needs, such as Post-It notes and Scotch tape."
