Human papillomavirus 16 (HPV16), the virus responsible for approximately half of all cervical cancers, appears to be better at dodging the immune system than other HPV types, according to a large study of HIV-positive women in the July 16 issue of the Journal of the National Cancer Institute. The findings may help explain why HPV16 plays such a major role in causing cervical cancer in the general population.
Whereas other HPV types have a lower prevalence and incidence among women with stronger immune systems (in theory, the stronger the immune system, the better it is at fighting off infections), researchers detected similar levels of HPV16 in women with both weak and strong immune systems.
More than 30 types of HPV are known to infect the genital epithelium. HPV16 has been the strain most strongly associated with cervical cancer and its precursor lesions. What sets HPV16 apart from other HPV types has not been clear. A preliminary analysis of a study on HPV infection among women positive for HIV, the virus that causes AIDS, suggested that HPV16 may be less associated with immune status than other HPV types.

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...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters

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...
