New RNA polymerase discovered in plants

...ome strange floral defects. The plants were having trouble with organ identity ?stamens tried to turn into petals, for instance. Our first hypothesis was that the fourth polymerase was involved with what are known as micro RNAs, which are known to regulate flower development, but that proved wrong." In a se...

Protein offers way to stop microscopic parasites in their tracks

...like a time bomb that can go off and cause serious trouble when the immune system wanes or is compromised," explains L.

Mice brains shrink during winter, impairing some learning and memory

...an did the long-day mice, indicating they had more trouble learning where the platform was. Moreover, they didn't remember its location as well from one day to the next.

Purdue scientists may have found key to halting spinal cord damage

...em circulating in your bloodstream," he said. "The trouble is that when free radicals start attacking tissue, it happens in a tiny fraction of a second, after which they are gone.

Mysterious 'neural noise' actually primes brain for peak performance

... As you reach your decision, you'd have a lot of trouble articulating most of the variables your brain just processed for you.
