A specific enzyme that is a central part in the regulation of body temperature has been identified by a research team at Linkoping University, Sweden. The enzyme is a potential target in the development of new and selective fever reducing drugs.
Professor Anders Blomqvist, MD David Engblom and co-authors are publishing their findings in Nature Neuroscience.
Fever is caused when small, easily diffusible molecules known as prostaglandin E2 are bonded to receptors on deep neural structures and change the brains thermostat. However, the prostaglandins are not produced until the specific enzyme mPGES-1 signal an ongoing inflammation somewhere in the body.
By using genetically modified mice the researchers found evidence of this function. A group of mice lacking the gene for mPGES-1 were injected with a bacterial extraction. The same injection was given to a group of wild-type mice. The result was a consistent elevation of body temperature in the wild-type group, while modified mice remained feverless.

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...
