Identifying asymptomatic people with genital herpes infection through targeted screening of high-risk groups may prevent disease transmission. However, widespread screening of pregnant women is unlikely to reduce the occurrence of herpes in newborns, according to an article in the January 1 issue of Clinical Infectious Diseases, now available online.
Herpes simplex virus type 2 (HSV-2) infects more than one-fifth of the United States population, but about 90 percent of those people are unaware that they are infected, since most do not experience any symptoms. In this case, though, ignorance is not bliss--a person infected with HSV-2 can unknowingly pass the virus to sexual partners and has a doubled risk of contracting HIV from unprotected sex.
Screening for HSV-2 has become possible with the advent of a blood test that can detect antibodies to the virus. A committee of sexually transmitted disease (STD) experts in California considered the potential risks and benefits of HSV-2 screening in four groups of asymptomatic people: people at high risk for STDs, HIV-positive people, people whose partners have HSV-2 and pregnant women. The authors found that the first three groups are likely to benefit from screening for HSV-2. Infected individuals could be counseled regarding condom use and advised about changing their behavior to reduce the risk of acquiring HIV or transmitting genital herpes.

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...
