A promising experimental compound prevents cholesterol gallstone disease in mice by stimulating the biochemical pathway that controls bile acid secretion by the liver, according to new studies by Howard Hughes Medical Institute researchers.
The findings suggest new approaches to developing drugs to prevent the disease, which afflicts some 20 million people a year. The studies also propose novel strategies for developing diagnostic tests to identify people with a genetically increased risk for developing gallstones.
A research team led by David J. Mangelsdorf, a Howard Hughes Medical Institute (HHMI) investigator at the University of Texas Southwestern Medical Center at Dallas, published its findings November 21, 2004, in the advance online version of the journal Nature Medicine. Co-authors of the paper included HHMI research associate Antonio Moschetta and Angie Bookout in Mangelsdorf’s laboratory.

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...
