Novel and efficient inhibitors of anthrax lethal factor identified by Burnham team
A collaborative team of scientists led by The Burnham Institutes Maurizio Pellecchia, Ph.D., has identified inhibitors of the anthrax toxin, termed lethal factor ("LF") that could be developed into an emergency treatment for exposure to inhalation anthrax. These findings will be published by the Proceedings of the National Academy of Sciences by Early Edition at the journals website the week of June 20th.
Bacillus anthracis ("anthrax") is a proven agent of biological terrorism. Pulmonary anthrax, in which spores of the anthrax bacteria are inhaled, is typically fatal unless diagnosis is made at an early stage of infection, when antibiotics such as Ciprofloxacin can provide a complete cure. At late stages in the disease, antibiotics can kill the anthrax bacteria, but do not affect LF secreted by the bacteria, which is sufficiently concentrated in the bloodstream. LF enters cells and inactivates a human protein called "mitogen-activated protein kinase", or "MAPKK", disrupting the normal signaling pathways of the cell and inducing cell-death.

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...
