New technique could lead to more effective therapies for AIDS
When researchers came up with the powerful cocktail of anti-HIV drugs known as highly active antiretroviral therapy (HAART), they hoped they had found a way to finally rid the body of the virus. But they were wrong. The virus instead goes into hiding, dormant and practically undetectable in the body – and impervious to attack. While HAART manages to keep the virus at bay, its still quite capable – given the right opportunity – of replicating and wreaking havoc on the bodys immune system.
Now, virologists at Jefferson Medical College, led by Roger J. Pomerantz, M.D., professor of medicine, biochemistry and molecular pharmacology and director of the Division of Infectious Diseases and Environmental Medicine at Jefferson Medical College of Thomas Jefferson University in Philadelphia, may have found a way to bring HIV out of hiding. They have shown that an immune cell protein called interleukin-7 (IL-7) can rouse the virus better than previously tried agents, making it vulnerable to drugs and the bodys immune system. If the new technique proves its mettle, the work could lead to improved treatments for HIV infection, and might be a step toward complete viral eradication.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
