Supply questions asked as rare earths are getting rarer

Supply questions asked as rare earths are getting rarer

Posted Mon, 10 Oct 2011 16:18:00 GMT by Dave Armstrong

The elements rarest in the Earth (rare earth) are the most expensive, until we mine the Moon or Mars. However, rare earth minerals are increasingly used in new technologies such as electric vehicles, photovoltaic cells and smart phone displays. At a conference in Minneapolis, the Geological Society of America is discussing a situation that is beginning to cause problems.

We still receive gamma rays from the Crab Nebula's pulsar source, six million light years away. What is amazing astronomers is the sheer energy, even more than the first-seen light rays. Even a year ago, 100 GeV (electron - volts) was not expected from these pulses or anywhere else.

The European Space Agency's Venus Express spacecraft has detected an ozone layer in Venus' atmosphere, much as on Earth. Unlike Earth, however, the ozone is not the result of biological activity.

Old images taken by the Hubble Space Telescope have allowed astronomers to calculate the orbits and other characteristics of the only known exosystem with four planets circling a distant star. Astronomers reviewing old images taken by the Hubble Space Telescope in 1998 have discovered evidence of two planets that were missed the first time around.

German scientists say they've developed a new, lighter lithium-ion battery for use in electric cars. The batteries, which can be mass-produced, should save 25% on weight. Although carbon-fiber technology is common in aircraft design, carbon-fiber composite materials are challenging to work with, and have proven difficult to mass-produce in complex designs. Until now.

A webcam has been set up to watch Mount Everest. Installed on Kala Patthar by the Ev-K2-CNR committee from the city of Bergamo with a perfect view of its magnificent neighbour Mount Everest, the world's highest peak is now on camera for all to see from 0:15 a.m. to 12:15 p.m. C.E.T. via the world's highest webcam and is powered by solar energy.

As we all tend to fly because of employment, vacation or a migration of some kind, the creation of a new fuel efficient plane would be relevant to our everyday lives. So NASA proposed the Green Aviation Prize, with record first place prize money of $1.35 million.

Planet Mercury's secrets are unraveling, thanks to a flood of new information from NASA's orbital spacecraft, MESSENGER. Launched some six years ago, MESSENGER, or the MErcury Surface, Space ENvironment, GEochemistry, and Ranging spacecraft, is the first in history to orbit the fiery, innermost planet.

While the speed of light is accurately measured at 299,792,458 metres per sec (700 million mph) neutrinos have just been policed at an unexpected higher rate over a 450 mile test. While the rate is a mere 60 nanoseconds faster, the incredible fact is that the speed difference is actually 12,000 mph!

Scientists revise long-held beliefs about plant biodiversity and biomass

For decades, scientists have believed there is a particular relationship between the biomass produced by plants and the number of different plant species in a given habitat. New research published in the journal Science shows that a long held belief about the relationship between plant biomass and plant diversity is flat wrong.

So relevant to all life forms and our climate, the sea's salt has now been estimated by NASA's  Aquarius/SAC-D satellite observatory. After two and a half weeks, since only August 25th, the preliminary data have been exemplary, providing us with an early view of large-scale ocean patterns.

NASA's UARS sattelite is expected to plunge back to Earth in the very near future, but no one knows exactly when, or where, debris may land. Although the satellite will break up upon re-entry, not all of the pieces are expected to burn up in the atmosphere.
