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.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
