Bangladeshi women prefer pollution-causing cookstoves Posted: 29 Jun 2012 11:25 AM PDT Women in rural Bangladesh prefer inexpensive, traditional stoves for cooking over modern ones despite significant health risks, according to a new study.

New technique could reduce number of animals needed to test chemical safety Posted: 29 Jun 2012 11:25 AM PDT A new way of testing the safety of natural and synthetic chemicals has been developed. The new research could reduce the number of fish needed to test the toxicity of a range of chemicals including pharmaceuticals and environmental pollutants.

Britain's urban rivers bounce back Posted: 29 Jun 2012 11:25 AM PDT After decades of pollution, typically from poorly treated sewage and industrial waste, rivers in or near Britain's major urban areas are regaining insects such as mayflies and stoneflies that are typical of fast-flowing, oxygen-rich waters.

Oldest Neolithic bow discovered in Europe Posted: 29 Jun 2012 11:24 AM PDT Researchers have discovered the oldest Neolithic bow in Europe at La Draga Neolithic site in Banyoles. The complete bow measures 108 cm long and was constructed of yew wood.

A slow trek towards starvation: Scott's polar tragedy revisited Posted: 29 Jun 2012 09:04 AM PDT On the centenary of Scott's ill-fated Terra Nova expedition to the South Pole, a new study has shown that Scott's men starved to death because they were consuming far too few calories to fuel their daily exertion.

EU's carbon allocation scheme and Scandinavia's carbon taxes have not reduced greenhouse gas emissions Posted: 29 Jun 2012 09:03 AM PDT The European Union implemented a cap and trade scheme in 2005 to help it fulfil its obligations under the first phase of the Kyoto Protocol for reducing carbon emissions. The Scandinavian nations had independently imposed a carbon tax in the 1990s as part of their effort to reduce carbon emissions. US researchers have tracked the carbon disclosures from both regions of Europe and found that neither the EU's carbon allocation scheme nor Scandinavia's carbon taxes have made any significant impact on reducing greenhouse gas emissions.

TB treatment paradox: Mouse studies show body's own response helps TB bacteria survive Posted: 28 Jun 2012 11:57 AM PDT Inhibiting a key immune response in mice during initial multi-drug treatment for tuberculosis could -- paradoxically -- shorten treatment time for the highly contagious lung infection according to new research.

Looking for the next American hyrax? Audience-loving animals express multiple traits through their songs Posted: 28 Jun 2012 11:57 AM PDT Recent research has uncovered more nuances in the hyrax song, including its variations among different functions, contexts, and reception. Though birds are well-known for their singing, more complex vocalizations are rare in mammals -- so hyraxes may provide long-sought answers about how animals communicate.

Saving the Baltic Sea: Geo-engineering efforts to mix oxygen into the Deep Baltic should be abandoned, expert says Posted: 28 Jun 2012 11:56 AM PDT Over the last decade, an average of 60,000 square kilometers of the Baltic Sea bottom has suffered from hypoxia without enough oxygen to support its normal ecosystem. Several large-scale geoengineering interventions are currently on the table as proposed solutions to this problem. Researchers are calling for geoengineering efforts that mix oxygen into the Deep Baltic to be abandoned.

Giant raft of data to help us understand disease Posted: 28 Jun 2012 11:56 AM PDT Scientists have used a new method to assemble a massive catalog of data on proteins. This gives them unprecedented insight into a process called protein phosphorylation.
