Biochemists at Ohio State University and their colleagues have overcome one of the major obstacles to drug design, by trimming some of the fat from a molecular sponge that scientists use to study proteins.
In the December issue of the journal Structure, the biochemists report using their method successfully in experiments with two common cellular proteins. The results suggest that scientists could one day use the method as a step in designing drugs for diseases such as cystic fibrosis, Alzheimer’s, and tuberculosis.
Proteins are part of the cell membranes of living organisms, and they are the gatekeepers that regulate what enters and leaves a cell, explained Martin Caffrey, professor of chemistry at Ohio State. To design a drug that will target a particular protein, scientists need to view the protein’s structure in detail, and that involves removing the protein from the cell membrane and forming it into a crystal that can be viewed using x-rays.

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...
