| First step to reduce plant need for nitrogen fertilizer uncovered Posted: 27 Sep 2013 03:33 PM PDT Nitrogen fertilizer costs US farmers approximately $8 billion each year, and excess fertilizer can find its way into rivers and streams, damaging the delicate water systems. A new discovery could be the first step toward helping crops use less nitrogen, benefiting both farmers' bottom lines and the environment. |
| New biological agent to fight invasive weed Posted: 27 Sep 2013 03:29 PM PDT Entomologists reached a milestone in their efforts to control the invasive weed swallow-wort this month with the first release of a biological agent to fight the pest. |
| New species of fascinating opportunistic shelter using leaf beetles Posted: 27 Sep 2013 09:34 AM PDT Builders are rather uncommon among adult leaf beetles though young ones of certain species use own feces to construct a defensive shield. Two closely related, hitherto unknown species of tiny southern Indian leaf beetles, only slightly larger than the size of a pin-head, and their clever way of using and modifying low cost shelters, have now been described. |
| Breathing underwater: Evidence of microscopic life in oceanic crust Posted: 27 Sep 2013 06:27 AM PDT Scientists have recently documented that oxygen is disappearing from seawater circulating through deep oceanic crust, a significant first step in understanding the way life in the "deep biosphere" beneath the sea floor is able to survive and thrive. The new research findings are helping to redefine our concepts of the limits of life on our planet. |
