Scientists revise long-held beliefs about plant biodiversity and biomass

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.

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.

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.

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.

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.

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.

Three year study discovered a chemical providing a natural sunscreen which could be manufactured for humans. The role of photosynthesis within the process means the coral needs to live close to the surface of the water, raising the risk of sunburn and damage from direct sunlight.

Plans to get astronauts all the way to Mars and back will need to include room for a space garden, according to a presentation at the American Chemical Society meet in Colorado this week. Not only will the garden provide the Mars-bound travelers with a little culinary sparkle to their diet - it will help to help to keep the capsule's atmosphere breathable, and its water clean.

A report on a technology for harvesting power 'on-the-move' offers the promise of mobile devices being freed from the grid. Cell phones, laptops and a myriad of other electrical gadgets could benefit from an innovative shoe-powered device, say a University of Wisconsin-Madison duo in this week's Nature Communications.

There are both good and bad effects of social networking use says an American psychologists, who encourages parents to listen and understand rather than spy. The bad news is that teenagers who use Facebook are more often narcissistic and young adults who use the site heavily are more likely to suffer psychological disorder.
