Solar flare cycle driven by rivers of plasma
Posted Thu, 03 Mar 2011 15:34:00 GMT by Martin LeggettNew models of the huge streams of plasma on the surface of the Sun are raising understanding of the complex mechanisms at play. As the solar sunspot cycle picks up speed, and starts sending out new flares towards the Earth, understanding exactly what makes the Sun tick looks to be increasingly important for the stability communications and power systems, as well as of the climate.

Florida, the sunshine state just got 10 million years older
Posted Thu, 03 Mar 2011 14:21:00 GMT by Martin LeggettFlorida, the sunshine stats may not be as youthful as looks suggest. A new analysis of samples collected from water boreholes have pushed back the time, when Florida first emerged from the sea, to 45 million years ago. The study describes a familiar landscape of palm trees and islands, and provides useful information for those looking to keep water flowing for local residents.

Buildings that repair and heat themselves
Posted Thu, 03 Mar 2011 13:03:06 GMT by Martin LeggettA new approach to getting organic materials into tiny glass beads opens up a number of new possibilities for intelligent cement that can heal cracks, and regulate temperatures. This exciting development is described in a thesis presented to the University of the Basque Country, and raises the prospect of buildings lasting longer and requiring less energy to be heated and cooled.

Crop diversification may help protect farmers from climate change
Posted Wed, 02 Mar 2011 20:06:00 GMT by Colin RickettsMonocultures might be the most efficient way to grow but they're also great for the nasties that destroy crops a new report finds. Now scientists have come up with a very good reason for farmers to grow a wider diversity and variety of crops to protect themselves from the changes likely to result from climate change.

A warming beer! Scientists look for biofuels in brew waste
Posted Mon, 28 Feb 2011 15:23:02 GMT by Colin RickettsMicrobes in brewery waste already saves brewers millions by producing methane and now scientists want to put these miniature workers to work on other useful tasks. Cornell scientists have been working with Anheuser-Busch Inbev, which brews Budweiser, to see if microbes which currently produce methane as they break down brewery waste can be put to other uses

Using less fertilizer aids corn for fuel
Posted Mon, 28 Feb 2011 15:07:01 GMT by Martin LeggettProducing bioethanol from corn residues offers a potentially new twist on the food versus fuel debate. New research suggests that maximizing cellulose production from such residues requires less fertilizer - which also has environmental benefits. But how will that impact grain yields?

Warming world could send plants downhill, not up
Posted Fri, 25 Feb 2011 12:21:01 GMT by Laura GoodallA hotter climate could make some plants move downhill to seek water, suggests new research that challenges the assumption that plants would move uphill to reach cooler elevations. Scientists at the University of Montana, the University of California, Davis, and the University of Idaho are the first to find a widespread downward shift in Californian mountain plants.

Scavenger T.rex much more like a hyena than a lion
Posted Wed, 23 Feb 2011 17:02:00 GMT by Louise MurrayAn epic Montana fossil bed census suggests Tyrannosaurus rex was more of an opportunistic scavenger like a hyena, than an apex predator like a lion. This is the largest study of its kind in the world and the first complete picture of an ancient ecosystem dominated by dinosaurs.

'Thunderthighs' - a new species of dinosaur discovered
Posted Wed, 23 Feb 2011 12:22:00 GMT by Louise MurrayA new species of dinosaur, Brontomerus, literally 'thunderthighs', has been found in a quarry in Utah, USA. Named for it's extremely large thigh muscles, the larger than elephant-sized beast may have used them to kick fight predators or rivals.

Biodiesel produced from wastewater microalgae
Posted Sun, 20 Feb 2011 10:04:00 GMT by Lucy BrakeScientists have developed a way to extract a new kind of biodiesel from microalgae. They have worked out that once the microalgae have been through the treatment system and purified the wastewater then it can potentially be used to run construction vehicles, buses and farm equipment.

John Michael Greer Looks Forward to Our Ecotechnic Future
Posted Fri, 18 Feb 2011 12:33:01 GMT by Julian JacksonBook Review of an excellent road map to a possible future way of living. The American Archdruid - yes, he really is a druid - and ecological author John Michael Greer has written a book called The Ecotechnic Future: Envisioning a Post-Peak World, a follow-on to his analysis of the short term predicament our society is in: The Long Descent.

Did some dinosaurs survive the mass extinction?
Posted Wed, 16 Feb 2011 09:59:00 GMT by Michael EvansA new method of dating indicates that a New Mexico dinosaur was alive 700,000 years after the ''mass extinction'' of all the others. Is it possible that the previously accepted date is wrong? Researchers from the University of Alberta have cast shadow of doubt on this timescale after they examined a fossilised hadrosaur bone that was discovered in New Mexico.

Evolution stumbling block to strong scientific education in US
Posted Tue, 15 Feb 2011 16:31:00 GMT by Michael EvansThe reluctance of US high school science teachers to teach evolutionary biology is causing a major stumbling block in the provision of a sound scientific education. Evolution is one of those things that you either believe in or you don't and recent research indicates that more than half of US public school science teachers are not strong advocates of evolutionary biology.

Lithium-air batteries a thing of the future, scientists say
Posted Mon, 14 Feb 2011 17:37:00 GMT by Rachel EnglandAdvances in battery technology such as lithium-air batteries are unlikely to happen soon. Electric vehicles are gaining popularity around the world, but their potential for becoming completely mainstream remains hampered by the limited range of their lithium-ion batteries.

Biodiversity is the term given to the variety of life on Earth and the natural pattern it forms. The biodiversity we see today is the result of millions of years of evolution, initially shaped by natural processes, but in modern times increasingly as a result of human intervention. We are an integral part of the web of biodiversity and we depend on this web, as does every other life form on the planet.
