Until now, scientists believed that a single area in the brain generated breathing rhythm, enabling breathing to speed up or slow down to adapt to the body’s activity and position. But UCLA neurobiologists have discovered that two systems in the brain interact to generate breathing rhythm — a finding that may translate into better treatment for sleep apnea and sudden infant death syndrome. The journal Neuron reported the findings in its March 6 issue.
“We originally thought that only one brain center was responsible for generating breathing rhythm,” said Dr. Nicholas Mellen, UCLA assistant researcher in neurobiology and principal investigator of the study. “But our research indicates that two cellular networks closely collaborate to control breathing. This brings us an important step closer to understanding how breathing control is organized in the brain.”
“Breathing is a good model for understanding brain function in general,” said Dr. Jack Feldman, UCLA professor of neurobiology and senior author. “Once we learn how the brain commands humans to breathe, we will gain valuable insight into how the brain produces other meaningful behaviors.”

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
