A newly established national biomedical center at Cornell University is reporting its first major advance: a new way of measuring, or "visualizing," proteins. The new technique will hasten the transformation of the human genome project’s blueprints of life into a comprehensive view of the biochemical and physiological circuitry that interconnect to form entire organisms.
The technique, which determines the structure of a protein by measuring the distances between atoms in the molecule at greater separations than previously possible, is an important development, says Jack Freed, professor of chemistry and chemical biology at Cornell, who is director of the National Biomedical Center for Advanced ESR Technology (ACERT), established at Cornell last year by the National Institutes of Health. "This is in the spirit of seeing the whole forest of the protein, whereas before we have been seeing the trees one after another," says Freed.
Freed and his collaborators, Hassane Mchaourab, professor of molecular physiology and biophysics at the Vanderbilt University School of Medicine, and Peter Borbat, associate director of ACERT, report on the new method for protein structure determination in JACS , the Journal of the American Chemical Society (May 22, 2002).

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...
