One of the most devastating diseases in sub-Saharan Africa almost disappeared in the late 1950s. That disease, African sleeping sickness, or trypanosomiasis, largely succumbed to heroic public health efforts -- including relocating entire villages. But in the past several decades, because of post-colonial turmoil, the catastrophic illness has come back to ravage parts of Angola, the Democratic Republic of the Congo, the Sudan and other countries. In some regions, the tsetse fly-borne infection rivals or exceeds the toll AIDS takes.
Trypanosomiasis is passed from human to human by tsetse fly bites. It produces fever, lymph nodes inflammation, eventual impairment of the brain and nervous system in its late stage and, if not treated, death. The World Health Organization has estimated that more then 300,000 people are infected, and more than 60 million living in the region are at risk.
Now, real hope for a better treatment is on the horizon, based on research conducted in part at the University of North Carolina at Chapel Hill. In Phase II clinical trials, a new oral drug, DB289, demonstrated safety and high effectiveness in subjects with the early stage of sleeping sickness. Scientists are launching a Phase III trial this summer involving for the first time hundreds of patients who will be treated with the drug.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
