(A2) Seismologists have developed a new system that could be used to warn future populations of an impending tsunami only minutes after the initial earthquake. The system, known as RTerg, could help reduce the death toll by giving local residents valuable time to move to safer ground. The study by researchers at the Georgia Institute of Technology appears in the March 5 edition of Geophysical Research Letters. "We developed a system that, in real time, successfully identified the magnitude 7.8 2010 Sumatran earthquake as a rare and destructive tsunami earthquake. Using this system, we could in the future warn local populations, thus minimizing the death toll from tsunamis," said Andrew Newman, assistant professor in the School of Earth and Atmospheric Sciences.
Typically, a large subduction zone earthquake ruptures at a rate near 3 kilometers/second and anywhere from 20 kilometers to 50 kilometers below the earth's surface.
Because of the depth, vertical deformation of the crust is horizontally smoothed, causing the size of uplift to remain rather small. When these earthquakes occur in the ocean, the resulting waves may only measure about 20 centimeters high for a magnitude 7.8 event.
(The Guardian) Those of us waiting patiently for the era of flying cars have been stung before. Usually by some delusional old tinkerer appearing on Tomorrow's World or Blue Peter, tantalisingly showing off some hovering hatchback or Cortina-with-wings and promising it'll be an everyday form of transport – soon. It never happens. As the characters in Bill Watterson's Calvin and Hobbes comic strip complained way back in 1989: "A new decade is coming up. Big deal! Where are the flying cars?"
Finally, in 2011, some action. Later this year an American company called Terrafugia will go into "low volume production" on its Transition Roadable Aircraft – a genuine, non-delusional, you-can-actually-buy-it-and-it-actually-flies flying car. It looks a bit like the Ghostbusters' vehicle with fold-out wings, and will cost something between £125,000 and £160,000. Terrafugia CEO Carl Dietrich hopes to sell 200 a year.
Hundreds of herbal medicinal products will be banned from sale in Britain next year under what campaigners say is a "discriminatory and disproportionate" European law.
With four months to go before the EU-wide ban is implemented, thousands of patients face the loss of herbal remedies that have been used in the UK for decades.
From May 1, 2011 on, traditional herbal medicinal products must be licensed or prescribed by a registered herbal practitioner to comply with an EU directive passed in 2004. The directive was introduced in response to rising concern over adverse effects caused by herbal medicines.
For the last few years the word “accelerometer” has become synonymous with Smartphones. But now the tech is taking a jump into clothing thanks to the innovative folks at Under Armour.
They’ve developed a shirt called the E39, which combines a 4.5oz electronic monitor with their compression shirt tech. It measures everything from accelerometry, to breathing rate, to skin surface temperature to heart rate. Inside the tiny device, which was designed by Zephyr tech, is an SD card which stores the computer’s recorded data along with a wireless Bluetooth module which instantly transmits data to a connected computer, tablet or smartphone.
So what does this mean to athletes? Coaches and those alike can now monitor their performance with real time data and provide them with the instantaneous feedback to adjust their game, quite literally. A triaxial accelerometer measures acceleration and change of direction, which helps determine what part of an athlete’s stride is out of sync and thus enabling them to modify their movements on the fly and improve their running speed or agility.
A European spacecraft that skims the upper reaches of the atmosphere has mapped Earth's gravity with unrivaled precision. The map below shows how the pull of gravity varies minutely over the surface of the Earth, from deep ocean trenches to majestic mountain ranges.
The measurements have allowed scientists to create a computer model called a 'geoid' that reveals what Earth would look like if its shape were altered to make gravity equal at every point on the surface.
Researchers unveiled the latest data from the European Space Agency's Gravity and Ocean Circulation Explorer, or Goce, at a workshop in Munich on Thursday.
