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.

The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.
