| 'Rock dissolving' method of geoengineering to mitigate climate change would not be easy Posted: 21 Jan 2013 04:20 PM PST The benefits and side effects of dissolving particles in our ocean's surfaces to increase the marine uptake of carbon dioxide, and therefore reduce the excess amount of it in the atmosphere, have been analyzed in a new study. Researchers calculate that if three gigatons of olivine were deposited into the oceans each year, it could compensate for only around nine per cent of present day anthropogenic CO2 emissions. |
| Posted: 21 Jan 2013 01:18 PM PST Ancient DNA has revealed that humans living some 40,000 years ago in the area near Beijing were likely related to many present-day Asians and Native Americans. |
| Human-tiger conflict: Are the risks overestimated? Posted: 21 Jan 2013 07:33 AM PST A new study has found a complex web of factors increases perceived risk of tiger attack in the Sundarbans of Bangladesh. Wildlife conservationists are well aware of the potential conflicts that exist between the endangered species they seek to protect and the human populations which inhabit areas where the animals live. Carnivores, such as tigers, pose a risk to humans and their livestock and can be killed because of this potential risk. A new study has identified several key factors which may contribute to perceptions of risk from tigers in a conservation area in Bangladesh. |
| Molecular forces are key to proper cell division Posted: 21 Jan 2013 07:33 AM PST New details emerge about a molecular surveillance system that helps detect and correct errors in mitosis that can lead to cell death or human diseases. Biologists can watch and record images of the key players including microtubules, kinetochores, molecular engines and the polar ejection force. |
| Did an 8th century gamma ray burst irradiate Earth? Posted: 21 Jan 2013 05:32 AM PST A nearby short duration gamma-ray burst may be the cause of an intense blast of high-energy radiation that hit the Earth in the 8th century, according to new research. |
| Scientists describe a 'new' type of volcanic eruption Posted: 21 Jan 2013 05:32 AM PST Scientists based in the UK and New Zealand have described a "new" type of volcanic eruption. Volcanic eruptions are commonly categorized as either explosive or effusive. But now, researchers have uncovered a previously undocumented type of eruption in underwater volcanoes – by looking at tiny original bubble spaces trapped in volcanic rock. |
| Posted: 21 Jan 2013 05:30 AM PST A new imaging method for the study of insulin-producing cells in diabetes among other uses has been developed. |
| Mars may have supported life: Martian underground could contain clues to life's origins Posted: 20 Jan 2013 11:58 AM PST Minerals found in the subsurface of Mars, a zone of more than three miles below ground, make for the strongest evidence yet that the red planet may have supported life, according to new research. |
