No-entry zones for AIDS virus
The AIDS virus inserts its genetic material into the genome of the infected cell. Scientists of the German Cancer Research Center have now shown for the first time that the virus almost entirely spares particular sites in the human genetic material in this process. This finding may be useful for developing new, specific AIDS drugs. view more (2009-11-13)
Scientists decipher the formation of lasting memories
Researchers at Karolinska Institutet have discovered a mechanism that controls the brain's ability to create lasting memories. In experiments on genetically manipulated mice, they were able to switch on and off the animals' ability to form lasting memories by adding a substance to their drinking water. view more (2009-11-11)
A Potential Anti-cancer Agent
Pateamine A (PatA), a natural product first isolated from marine sponges, has attracted considerable attention as a potential anti-cancer agent, and now a new activity has been found for it, which may reveal yet another anti-cancer mechanism. view more (2009-11-03)

New findings about brain proteins suggest possible way to fight Alzheimer's
The action of a small protein that is a major villain in Alzheimer's disease can be counterbalanced with another brain protein, researchers at UT Southwestern Medical Center have found in an animal study. view more (2009-10-07)
Novel 'on-off switch' mechanism stops cancer in its tracks
A tiny bit of genetic material with no previously known function may hold the key to stopping the spread of cancer, researchers at Yale School of Medicine and Sichuan University in Chengdu, China report in two papers in the September 7-11 issue of Proceedings of the National Academy of Sciences. view more (2009-09-24)

How HIV cripples immune cells
In order to be able to ward off disease pathogens, immune cells must be mobile and be able to establish contact with each other. The working group around Professor Dr. Oliver Fackler in the Virology Department of the Hygiene Institute of the Heidelberg University Hospital has discovered a mechanism in an animal model revealing how HIV, the AIDS... view more...

Skin-disease patients show brain immunity to faces of disgust
People with psoriasis - an often distressing dermatological condition that causes lesions and red scaly patches on the skin - are less likely to react to looks of disgust by others than people without the condition, new research has found. view more (2009-08-28)
Bladder cells feel stretch
Japanese research group led by Prof. Makoto Tominaga and Dr. Takaaki Sokabe (National Institute for Physiological Sciences: NIPS), and Prof. Masayuki Takeda, Dr. Isao Araki and Dr. Tsutomu Mochizuki (Yamanashi Univ.), found that bladder urothelial cells have a sensor for stretch stimulation. view more (2009-08-07)
Bacteria pack their own demise
Numerous pathogens contain an 'internal time bomb', a deadly mechanism that can be used against them. After years of work, VIB researchers at the Vrije Universiteit Brussel (VUB) were able to determine the structure and operating mechanism of the proteins involved. view more (2009-07-31)
