Cholesterol levels vary with the seasons, reaching their highest levels in the winter months, according to an article in the April 26 issue of The Archives of Internal Medicine, one of the JAMA/Archives journals.
According to the article, a variety of studies have suggested that cholesterol levels are higher in the fall and winter than they are in the spring and summer. Although the mechanism for this phenomenon is not clear, such variation could result in larger numbers of people being diagnosed as having high cholesterol in the winter, the article states.
Ira S. Ockene, M.D., of the University of Massachusetts Medical Center, Worcester, and colleagues investigated the seasonal variation in cholesterol among 517 healthy volunteers from a health maintenance organization serving central Massachusetts. Data were collected quarterly over a twelve-month period on diet, physical activity, exposure to light, general behavioral information, and cholesterol levels were also measured.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
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...
