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.”

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
