Brown research reveals key insight into memory-making

...urs, even days, and is believed to be the cellular basis for memory. AMPA receptors on the membrane of the information-receiving neuron, known as the postsynaptic cell, act like gates, opening in response to chemical messages from a neighboring neuron. During LTP, extra AMPA receptors appear, increasing sy...

Poplar DNA code cracked -- a step in combating global warming?

... will identify the genes in the poplar DNA. On the basis of mathematical algorithms, the researchers predict that the poplar has around 50,000 genes, and they anticipate that about 10,000 of them are not found in Arabidopsis and are therefore possibly 'tree-specific'. A variety of applications With the ...
