| Sensitivity of carbon cycle to tropical temperature variations has doubled Posted: 26 Jan 2014 10:46 AM PST The tropical carbon cycle has become twice as sensitive to temperature variations over the past 50 years, new research has revealed. The research shows that a one degree rise in tropical temperature leads to around two billion extra tons of carbon being released per year into the atmosphere from tropical ecosystems, compared with the same tropical warming in the 1960s and 1970s. |
| Engineers teach old chemical new tricks to make cleaner fuels, fertilizers Posted: 26 Jan 2014 10:46 AM PST University researchers from two continents have engineered an efficient and environmentally friendly catalyst for the production of molecular hydrogen, a compound used extensively in modern industry to manufacture fertilizer and refine crude oil into gasoline. |
| Blue eyes and dark skin, that's how the European hunter-gatherer looked: 7,000-year-old genome shows Posted: 26 Jan 2014 10:46 AM PST La Braña 1, the name used to baptize a 7,000-year-old individual from the Mesolithic Period whose remains were recovered at La Braña-Arintero site in Valdelugueros (León, Spain), had blue eyes and dark skin. |
| Picture of how our climate is affected by greenhouse gases is a 'cloudy' one Posted: 26 Jan 2014 10:46 AM PST The warming effect of human-induced greenhouse gases is a given, but to what extent can we predict its future influence? That is an issue on which science is making progress, but the answers are still far from exact, say researchers. |
| Drug to reverse breast cancer spread in development Posted: 25 Jan 2014 07:49 PM PST Researchers at Cardiff University are developing a novel compound known to reverse the spread of malignant breast cancer cells. The vast majority of deaths from cancer result from its progressive spread to vital organs, known as metastasis. In breast cancer up to 12,000 patients a year develop this form of the disease, often several years after initial diagnosis of a breast lump. In a recent series of studies, researchers identified a previously unknown critical role for a potential cancer causing gene, Bcl3, in metastatic breast cancer. |
| What's with Sloth's Dangerous Bathroom Break? Maybe Hunger Posted: 25 Jan 2014 02:22 PM PST For the three-toed sloth, a trip to the restroom is no rest at all. It's a long, slow descent into mortal danger from the safety of home among the upper branches of the forest. |
| Posted: 24 Jan 2014 07:17 AM PST Researchers identified two HIV-1 Envelope immunogens that elicit broadly neutralizing antibodies when introduced as a vaccine. |
| Biomarker for stress hormones in polar bears, wildlife affected by global climate change Posted: 24 Jan 2014 06:36 AM PST Researchers have reported fluctuations in climate and ice cover related to stress in polar bears as indicated by levels of cortisol in hair samples. |
| Exploring the roots of the problem: How a South American tree adapts to volcanic soils Posted: 23 Jan 2014 07:23 PM PST Soils of southern South America, including Patagonia, have endured disturbances from volcanic eruptions, earthquakes, landslides, and erosion. Also, massive fires in the mid-20th century were set to forests in order to promote colonization. In 2010, another 17,000 acres of Patagonia burned, fueling an international reforestation effort. Although the young soils of Patagonia may contain high phosphorus levels, the element is tightly bound to the soil. How can local plants take root and access that phosphorus? |
