Astrocytes and synaptic plasticity Oct 13, 2008
Astrocytes, previously thought to be unimportant in neuronal transmission, have recently been implicated in long-term modulation of neuronal synapses. For example, they release the neurotransmitter glutamate into the synapse prompting LTP. By specifically mopping up pro-BDNF, astrocytes seem to have another means to assist in LTP. However, while it's likely that most pro-BDNF gets degraded inside astrocytes, say the authors, some gets recycled and re-released, suggesting that astrocytes in fact... (EurekAlert!)
U.S. 'smart lighting' effort targets LED-based wireless networks Oct 10, 2008

They claim that each of these schemes can be made to work without flickering light, so long as data rates are above 900 KHz. (EETimes)
Cells Coordinate Gene Activity With FM Bursts, Scientists Find Oct 3, 2008
"Because the problem of coregulation of genes is very general, we suspect frequency modulation may be widespread across many genes, organisms, and cell types. We're now trying to determine how general this phenomenon is by looking at what other genes and cell types use this type of system," he says. The work was supported by grants from the National Institutes of Health and the Packard Foundation. (Science Daily)
