A group of researchers from The Scripps Research Institute (TSRI) have discovered rare genetic mutations in a subset of people who come down with a particular kind of severe sepsis, an acute and often deadly disease.
These rare mutations in a human gene called TLR4 lend susceptibility to meningococcal sepsis, which strikes over 2,500 people a year in the United States. About half of those who contract meningococcal sepsis are younger than the age of two, and the disease has an overall case fatality rate of 12 percent.
"Its a very fast-moving, dramatic, and often fatal disease," says TSRI Immunology Professor Bruce Beutler, who led the research, which will be published in an upcoming issue of the journal Proceedings of the National Academy of Sciences.

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...
