Nerves transmit sound waves through your body, not electrical pulses, according to a controversial new study that tries to explain the longstanding mystery of how anesthetics work.

Textbooks say nerves use electrical impulses to transmit signals from the brain to the point of action, be it to wag a finger or blink an eye.

"But for us as physicists, this cannot be the explanation," says Thomas Heimburg, a Copenhagen University researcher whose expertise is in the intersection of biology and physics. "The physical laws of thermodynamics tell us that electrical impulses must produce heat as they travel along the nerve, but experiments find that no such heat is produced."

The textbooks are not likely to be rewritten anytime soon, however.

Roderic Eckenhoff, a researcher in the Department of Anesthesiology and Critical Care at the University of Pennsylvania School of Medicine, called the sound pulse idea interesting. "But an enormous burden of proof exists and they have a very long way to go to beat electricity," he said.

The magnitude and nature of the E8 calculation invite comparison with the Human Genome Project. The human genome, which contains all the genetic information of a cell, is less than a gigabyte in size. The result of the E8 calculation, which contains all the information about E8 and its representations, is 60 gigabytes. This is enough to store 45 days of continuous music in MP3-format.

The mapping of E8 may well have unforeseen implications in mathematics and physics that won't be evident for years to come.

Breeders had attempted to make true blue roses for several years, but none had successfully bred roses with blue pigment until fairly recently. In its first commercial application in plants, technology was used to remove the gene encoding the enzyme dihydroflavonol reductase (DFR) in roses.
