    A scavenging immune system cell that helps limbs regrow in salamanders brings hope that humans will one day be able to mimic the animal's amazing regenerative powers, say Australian researchers. The findings by Dr James Godwin, of the Australian Regenerative Medicine Institute at Monash University, and colleagues, are published in today's issue of the Proceedings of the National Academy of Sciences.Salamanders (axolotls) are unique amongst vertebrates in being able to repair their hearts, tails, spinal cord and brain, and even regrow whole limbs during adult life, says Godwin.

Wayne Gronlund, who is coordinating the event, said he is trying to put together at least 50 amateur radio enthusiasts for TOPFF, a weeklong exercise that will include simulated terrorist attacks on ports in New London, New Jersey, Canada and the United Kingdom. “We know we're not going to have enough amateur radio resources in New London County to provide all...
