Researchers are probing details of how HIV commandeers genes in infected cells to disguise itself from the immune system. The researchers, from The Childrens Hospital of Philadelphia, have identified cellular proteins expressed during HIV infection that enable HIV-infected cells to avoid apoptosis, a common cell suicide event. This survival mechanism allows the virus to maintain the infection within the compromised cells.
These findings, as yet based on studies in cells, not in patients, may potentially lead to future treatments that could fully eliminate a patients HIV infection.
Current treatments for HIV and AIDS rely on a combination of drugs called highly active anti-retroviral therapy (HAART). "Although HAART drives down the HIV to undetectable levels, latent (or silent) infection may surge back if the treatment is interrupted," said the studys lead author, Terri H. Finkel, M.D., Ph.D., chief of Rheumatology at The Childrens Hospital of Philadelphia.

Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
