Plants' circadian clocks tune into latitude to enhance fitness
...t took the leaves to complete one circadian cycle, noted the time of day when the leaves were pointing straight upward, and calculated the distance the leaves moved during a cycle. All three measurements showed considerable differences in the plants from different areas. "When we determined day length in ...New pathway found to enhance cancer treatment

...ame age that Rett symptoms first appear. Greenberg noted that this gene, called BDNF, constantly flips back and forth between an "on" state, where it rapidly produces protein, and an "off" state, during which it's silent. "We knew a lot about how it was turned on," says Greenberg, "but we wanted to know w...RSRF-funded study leads to breakthrough for Rett Syndrome research
...isorders including Huntington's Disease. Greenberg noted that BDNF constantly flips back and forth between an "on" state, where it rapidly produces protein, and an "off" state, during which it is silent. "We knew a lot about how it was turned on," says Greenberg, "but we wanted to know what kept it off." ...Specialized brain helped ancient reptiles fly and hunt
...s of its body movements. Though other studies have noted the unusual size of the pterosaur flocculus, Witmer and his colleagues wanted to explore why it was so big and what it meant for the creature's ability to fly and hunt. The new study suggests that the bigger neural center was necessary to process sen...Case researchers discover the mouth's defenses against AIDS
...ing of the mouth that responded to HIV. Weinberg noted that hBD2 increased by almost 80 fold in the presence of HIV introduced to a monolayer of human oral epithelial cells grown in the lab and maintained their response rate for 72 hours--long after the time the virus could live in the conditions in th...Duke commits to enhance Primate Center

Cohn noted that the plasmatron reformer also allowed the NOx absorption catalyst to be effective at the low exhaust temperatures characteristic of urban use. These results indicate that the plasmatron reformer, in conjunction with an NOx absorber catalyst, coul...University of Minnesota receives NSF grant to sequence legume genome
