A multi-center research team has discovered how to deliver antimicrobial medications directly to the infectious parasites that cause diseases such as toxoplasmosis, even when the parasites lay hidden and inactive within cysts, where they have been untreatable by any available medicines.
The study, to be published online Nov. 17 by the Proceedings of the National Academy of Sciences, demonstrates the first effective, non-toxic method of transporting drugs across multiple membrane barriers and even into cysts of Toxoplasma gondii, the single-celled microorganism that causes toxoplasmosis. It also describes a new therapeutic target within this common parasite.
"This is a major step forward in developing ways to treat one of mankind’s most common chronic infections," said Rima McLeod, MD, professor of ophthalmology and visual sciences at the University of Chicago, who led the study. "For the first time, we have access to this microbe in its latent stage, a part of its life cycle that was previously inaccessible. We also have a better means of delivering medicines to its active stage, as well a new target for treatment."

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...
