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.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
