May offer new approach to smallpox treatment
In a finding that represents an entirely new approach to treating viral diseases such as smallpox, scientists at Dana-Farber Cancer Institute and collaborating institutions have shown that infections can be stymied by interfering with signals used by viruses to reproduce in human cells.
The results, reported in the February issue of the Journal of Clinical Investigation, point to a possible strategy for broadly treating acute viral infections that affect millions of people worldwide. If the technique leads to a drug capable of treating people infected with the smallpox virus, it could eliminate the virus potential as a bioterror agent. "Certain current anti-viral medications have a number of shortcomings that make them less than ideal for treating and/or preventing illnesses," says the studys senior author, Ellis Reinherz, MD, of Dana-Farber. "The existing vaccine against smallpox, for example, poses potential health risks that make it a questionable candidate for protecting the public against an outbreak of the disease. The approach weve taken is based on a new understanding of the basic mechanisms of viral reproduction and movement –– the actual steps that take place once a virus has invaded the body."

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...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
