| New and old threats to soybean production Posted: 23 Jun 2011 02:41 PM PDT Researchers have identified the top pathogens, pests and weeds affecting soybean production in a new article. Soybean aphid, soybean rust, soybean cyst nematode, Sclerotina stem rot and the exotic pathogen, red leaf blotch, are discussed as some of the top biotic constraints that may affect soybean production now and in the future.  |
| Sleep switch found in fruit flies Posted: 23 Jun 2011 11:13 AM PDT Rather than count sheep, drink warm milk or listen to soothing music, many insomniacs probably wish for a switch they could flick to put themselves to sleep. Scientists have discovered such a switch in the brains of fruit flies.  |
| Social amoeba rely on genetic 'lock and key' to identify kin Posted: 23 Jun 2011 11:13 AM PDT Scientists have identified the genetic "lock and key" that enable the amoeba to tell kin from non-kin. Just as the uniforms of armies enable soldiers to differentiate foe from friend, these amoeba use the protruding proteins as a kind of flag. In this case, the flag that protruded differs among strains of the Dictyostelium. These differences are critical to the kin/non-kin discrimination.  |
| Genes at the flick of a light switch: Human cells fitted with synthetic signaling cascade Posted: 23 Jun 2011 11:12 AM PDT Researchers from Switzerland have fitted human cells with a synthetic signaling cascade that can be used to switch on and regulate genes via blue light. This "gene light switch" makes interesting therapies possible, which could be used to treat type 2 diabetes, for instance.  |
| Effects of stress can be inherited, and here's how Posted: 23 Jun 2011 10:01 AM PDT None of us are strangers to stress of various kinds. It turns out the effects of all those stresses can change the fate of future generation, influencing our very DNA without any change to the underlying sequence of As, Gs, Ts and Cs. Now, researchers have new evidence that helps to explain just how these epigenetic changes really happen.  |
