(PhysOrg.com) -- Cotton growers will be better able to keep an eye out for two common pests because of a comprehensive survey by Agricultural Research Service (ARS) scientists at College Station, Texas. http://www.physorg.com/news178912351.html Biology Tue, 01 Dec 2009 18:10:04 EST news178912351 (PhysOrg.com) -- Agricultural Research Service (ARS) scientists in Texas are staying up late to search for beneficial insects that feed on crops pest eggs at night. http://www.physorg.com/news174145326.html Biology Wed, 07 Oct 2009 14:42:32 EST news174145326 (PhysOrg.com) -- Agricultural Research Service (ARS) scientists are developing a system that saves water by using aerial imagery and ground-based sensors to determine the irrigation needs of small sections of cultivated fields. http://www.physorg.com/news172221466.html Space & Earth Tue, 15 Sep 2009 08:30:02 EST news172221466 Cis-OPDA (12-oxophytodienoic acid) is a highly reactive plant hormone which simultaneously serves as a precursor molecule of the metabolic "master switch" jasmonic acid. Both signal herbivory in leaves and shoots of plants and activate the plants' defense reaction against caterpillars. Cis-OPDA, when reaching the hemolymph of the caterpillar, has a negative effect on the animal, leading to premature pupation and, apparently, an impaired immune system. http://www.physorg.com/news172162300.html Biology Mon, 14 Sep 2009 16:30:01 EST news172162300 Field trials of a new cotton are verifying previous lab and greenhouse studies indicating the crop could become a source of protein for millions of malnourished people in the world. http://www.physorg.com/news171275222.html Biology Fri, 04 Sep 2009 09:40:02 EST news171275222 One chemist plus one new scientific discovery yields. . . an economic and environmental miracle. Almost overnight, a whole new industry springs up and breathes life into an economically-devastated region of the country. It creates millions of new jobs and pumps billions of dollars into the economy. Thousands of miles away, the discovery helps avert the potential decimation of old growth forests, where millions of spruce, fir, poplar, and other trees were being cut each year. http://www.physorg.com/news169810821.html Chemistry Tue, 18 Aug 2009 10:43:31 EST news169810821 (PhysOrg.com) -- Cotton candy has delighted children for a century. Now it may have found a new role: helping scientists grow replacement tissues for people. The flossy stuff may be just right for creating networks of blood vessels within laboratory-grown bone, skin, muscle or fat for breast reconstruction, researchers suggest. http://www.physorg.com/news153589816.html Chemistry Wed, 11 Feb 2009 15:50:55 EST news153589816 A plot of land on the campus of Auburn University shows that 110 years of sustainable farming practices can produce similar cotton crops to those using other methods. http://www.physorg.com/news141917212.html Biology Mon, 29 Sep 2008 14:26:52 EST news141917212 A study in northern China indicates that genetically modified cotton, altered to express the insecticide, Bt, not only reduces pest populations among those crops, but also reduces pests among other nearby crops that have not been modified with Bt. These findings could offer promising new ideas for controlling pests and maximizing crop yields in the future. The report will be published by the journal Science on Friday, 19 September. http://www.physorg.com/news140965624.html Biology Thu, 18 Sep 2008 14:07:04 EST news140965624
