Fisheries scientists and conservation ecologists have put aside their differences to collaborate in a study of overexploited commercial fisheries. They say that such ecosystems can be revived and managed sustainably with existing techniques, but that these measures are being patchily applied around the world. 
Purer water made possible by Sandia advance

By substituting a single atom in a molecule widely used to purify water, researchers at Sandia National Laboratories have created a far more effective decontaminant with a shelf life superior to products currently on the market.
Dinosaur Burrow Find Gives Climate Change Clues

On the heels of his discovery in Montana of the first trace fossil of a dinosaur burrow, Emory University paleontologist Anthony Martin has found evidence of more dinosaur burrows – this time on the other side of the world, in Victoria, Australia. The find, to be published this month in Cretaceous Research, suggests that burrowing behaviors were shared by dinosaurs of different species, in different hemispheres, and spanned millions of years during the Cretaceous Period, when some dinosaurs lived in polar environments.

Ever-growing cost of the planned Mars Science Laboratory threatens other space missions.
UK climate effects revealed in finest detail yet

Scientists in London yesterday delivered unprecedented regional climate projections for the United Kingdom, detailing how the nation — piece by piece, in sections measuring just 25 square kilometres — will probably be affected by climate change. The projections, which update the findings of the UK Climate Impacts Programme (UKCIP) from 2002, are the first of their kind worldwide.

Recently, images of melting sea ice and shrinking rainforests have highlighted the world's biodiversity crisis and made us aware of the need to find a balance between preserving natural ecosystems while still having enough land for human use.
"About 10 percent of the world's land surface is afforded formal protection. We need to manage that 10 percent as best as we possibly can to preserve biodiversity but also be mindful of human needs, such as food and fiber production," said Lars A. Brudvig, Ph.D., post-doctoral researcher in biology in Arts & Sciences at Washington University in St
Biological Particles Trigger Ice Formation In High-altitude Clouds

A team of UC San Diego-led atmospheric chemistry researchers moved closer to what is considered the "holy grail" of climate change science when it made the first-ever direct detection of biological particles within ice clouds.
Keep Biofuels Out of the Gas Tank

Biofuels work better if you don't put them directly into your car. That's the conclusion of a new study that shows that ethanol derived from corn and switchgrass allows cars to drive farther and emit less greenhouse gases if these crops are converted to electricity for powering electric vehicles rather than pouring the ethanol into the gas tank.

Two years after puzzling experiments threatened to shatter established models of ozone depletion in the atmosphere, Taiwanese chemists have published data that support the currently accepted theory.

New data from two experiments -- one in space, one on a balloon floating above Antarctica -- hint at a tantalizing detection of dark matter, the mysterious stuff comprising 85% of the universe's matter. The evidence is a reported excess of high-energy electrons and their antimatter counterparts, positrons, which could be created as dark matter particles annihilate or decay.
Climate Change: Halving Carbon Dioxide Emissions By 2050 Could Stabilize Global Warming
sea-maid submitted, created time 1 year 4 months (www.sciencedaily.com)
If CO2 emissions are halved by 2050 compared to 1990, global warming can be stabilised below two degrees. This is shown by two studies by a co-operation of German, Swiss and British researchers in the journal Nature.

Epidemiologist Larry Brilliant, who helped to eradicate smallpox, is to leave his job as head of Google.org, the search giant's philanthropic arm, to lead the Skoll 'Urgent Threats Fund', created this month by Jeffrey Skoll, former founding president of eBay and head of the Skoll Foundation.
Most Distant Detection Of Water In The Universe

Astronomers have found the most distant signs of water in the Universe to date. The water vapour is thought to be contained in a jet ejected from a supermassive black hole at the centre of a galaxy, named MG J0414+0534
