An unusual RNA structure in the SARS virus offers a promising target for antiviral drugs
...fferent types of RNA perform a variety of critical tasks in all living cells. Messenger RNA is the intermediary that carries genetic information from the DNA in the chromosomes to the cellular protein factories, called ribosomes, where the genetic information is translated into proteins. The ribosomes them...Weizmann Insitute scientists show how proteins beat the evolutionary stakes

...ain wave activity? Attention, learning, and memory tasks are correlated with 'theta' oscillatory activity (4-8 cycles per second or Hz). Animal experiments on neocortex, the largest part of cerebral cortex, suggest that networks of a particular type of deep-layer neuron may generate theta oscillations.
