This Geoid Is The Most Sophisticated Map Of Earth's Gravity Yet
GOCE's 'Potato Earth' View Yellow areas show the highest gravity, blue the lowest. ESA/HPF/DLR Since 2009 the European Space Agency’s Gravity field and steady-state Ocean Circulation Explorer ( GOCE ) has been mapping the Earth’s gravitational field, and today the agency released its most detailed model of the geoid to date. More potato-shaped than spherical, this latest model shows just how different gravity can be at different points on our planet. The geoid is, roughly speaking, a model of the earth that doesn’t follow the surface of the crust but rather the average ocean surface if the oceans were at equilibrium and extended through the continents--in other words, the shape the earth would take based on its existing gravitational field if the tides, currents, and crust features didn’t distort things.
Video: Magnetic Gels That Swim, Shimmy, and 'Walk'
Magnetic Gels on the Move Miklós Zrínyi of Semmelweiss University in Budapest, Hungary, has created some gels that are anything but gellin’. In fact, these gels are moving, shaking, and otherwise getting around with a little help from magnetism. The gel “snakes” --made from a mix of polymer and metal particles--bend to match the shape of any magnetic field exerted upon them. That means with a little ingenuity, these gels can be manipulated in a variety of ways using either permanent magnets or electromagnets, depending on the shape and strength of the fields.
Biometric wallet is 'virtually indestructible,' opens with your touch
This biometric wallet has a Bluetooth proximity alarm, carbon fiber shell, and fingerprint sensor for maximum security. It will set the rich and paranoid back about $825. Afraid someone might take something out of your wallet? If you have $825 to spend, fear no more. Dunhill is selling what it calls a “Biometric Wallet” that it claims is virtually indestructible and can only be opened with your fingerprint.Waveform Audio File Format ( WAVE , or more commonly known as WAV due to its filename extension), [ 3 ] [ 6 ] [ 7 ] [ 8 ] (also, but rarely, named, Audio for Windows [ 9 ] ) is a Microsoft and IBM audio file format standard for storing an audio bitstream on PCs . It is an application of the Resource Interchange File Format (RIFF) bitstream format method for storing data in "chunks", and thus is also close to the 8SVX and the AIFF format used on Amiga and Macintosh computers, respectively. It is the main format used on Windows systems for raw and typically uncompressed audio.
WAV
FLAC ( pron.: / ˈ f l æ k / ; Free Lossless Audio Codec ) is a codec ( compressor-decompressor or coder-decoder ) which allows digital audio to be losslessly compressed such that file size is reduced without any information being lost. Digital audio compressed by FLAC's algorithm can typically be reduced to 50–60% of its original size, and decompressed into an identical copy of the original audio data. FLAC is an open format with royalty-free licensing and a reference implementation which is free software . FLAC has support for metadata tagging, album cover art, and fast seeking. Though FLAC cannot store floating-point data, and playback support in portable audio devices and dedicated audio systems is limited compared to lossy formats like MP3 or uncompressed PCM , FLAC is supported by more hardware devices than competing lossless compressed formats like WavPack .

Barack Obama's top secret tent
22 March 2011 Last updated at 11:44 GMT By Rajini Vaidyanathan BBC News, Washington President Obama with members of his team in a mobile war room in a tent A rare photo, released by the White House, shows Barack Obama fielding calls from a tent in Brazil, to keep up with events in Libya. The tent is a mobile secure area known as a Sensitive Compartmented Information Facility, designed to allow officials to have top secret discussions on the move. They are one of the safest places in the world to have a conversation.
