Scientists shut down reproductive ability, desire in pest insects

Posted: 26 Aug 2013 03:29 PM PDT

Entomologists have identified a neuropeptide named natalisin that regulates the sexual activity and reproductive ability of insects. The finding may open new possibilities for environmentally friendly pest management.

Future water levels of crucial agricultural aquifer forecast

Posted: 26 Aug 2013 03:05 PM PDT

A study focuses on future availability of groundwater in the High Plains Aquifer. It finds that if current irrigation trends continue, 69 percent of the groundwater stored in the aquifer will be depleted in 50 years.

Breakthrough in DNA editing technology

Scientists have found a way to apply a powerful new DNA-editing technology more broadly than ever before.

RNA double helix structure identified using synchrotron light

Scientists successfully crystallized a short RNA sequence, poly (rA)11, and confirmed the hypothesis of a poly (rA) double-helix.

Insight into the origin of the genetic code

An analysis of enzymes that load amino acids onto transfer RNAs — an operation at the heart of protein translation — offers new insights into the evolutionary origins of the modern genetic code, researchers report.

Insight into marine life’s ability to adapt to climate change

A study into marine life around an underwater volcanic vent in the Mediterranean, might hold the key to understanding how some species will be able to survive in increasingly acidic sea water should anthropogenic climate change continue.

Carbon-sequestering ocean plants may cope with climate changes over the long run

Posted: 26 Aug 2013 07:01 AM PDT

A year-long experiment on tiny ocean organisms called coccolithophores suggests that the single-celled algae may still be able to grow their calcified shells even as oceans grow warmer and more acidic in Earth’s near future. The study stands in contrast to earlier studies suggesting that coccolithophores would fail to build strong shells in acidic waters.

Changing river chemistry affects Eastern US water supplies

Posted: 26 Aug 2013 07:00 AM PDT

Human activity is changing the basic chemistry of large rivers in the Eastern US, with potentially major consequences for urban water supplies and aquatic ecosystems, a new study has found.

Climate change: Ocean acidification amplifies global warming

Posted: 26 Aug 2013 06:58 AM PDT

Scientists have demonstrated that ocean acidification may amplify global warming through the biogenic production of the marine sulfur component dimethylsulphide (DMS). Ocean acidification has the potential to speed up global warming considerably, according to new research.
