Nanotubes and the dawn of the flexible solar cell

Posted Wed, 28 Sep 2011 09:22:00 GMT by Dave Collier

The development of a transparent, flexible conductor could have interesting implications for solar cell design. Northwestern University in the United States, has come up with a novel solution: an application of nano-technology to create a flexible material that is both transparent and conductive.

Breaking the Cosmic Speed Limit

Posted Sun, 25 Sep 2011 20:00:00 GMT by Dave Armstrong

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

Posted Sun, 25 Sep 2011 09:00:00 GMT by Dale Kiefer

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.

NASA Aquarius satellite maps ocean salinity

Posted Sun, 25 Sep 2011 03:10:00 GMT by Dave Armstrong

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.

All in the game: online players open up AIDS drug research

Posted Mon, 19 Sep 2011 14:18:00 GMT by Colin Ricketts

Far from being a waste of time, online games have proved vital in new research which could help design new AIDS drugs. Research results could prove a vital tool in developing new AIDS drugs as the players used a specially designed game called Foldit to come up with an accurate model of an enzyme from a virus similar to the deadly immune system condition.

Oldest woolly rhino emerges from frozen wilderness

Posted Sat, 17 Sep 2011 15:05:01 GMT by Colin Ricketts

An expedition to some of Tibet's remotest and most inhospitable country has yielded a wonderful result in the shape of a previously unknown giant woolly rhino fossil. At 3.7 million years old, it's also the oldest woolly rhino ever found by some distance, predating the previous earliest find by some 1.1 million years.

Sprinkle of seaweed to make more powerful, less toxic batteries

Posted Fri, 09 Sep 2011 14:40:00 GMT by Martin Leggett

A team from Clemson University and the Georgia Institute of Technology has turned to seaweed for help with pushing lithium batteries onto the next level - silicon-based electrodes that could boost charging capacity significantly. The work, published in today's online version of Science, also promises to slash costs, and ditch toxic chemicals previously needed in the manufacture of rechargeable lithium batteries.

Flame retardants that fight fire and pollution

Posted Wed, 31 Aug 2011 16:31:00 GMT by Martin Leggett

Scientists at Texas A&M University believe they have taken the first steps towards a more effective flame-retardant for clothes - one that shouldn't be as damaging to the environment as previous types of fire-proofing. The work is being presented today at the American Chemical Society, which is meeting for the 242nd time, in Denver, Colorado, all this week.
