In a serendipitous spin-off of HIV/AIDS research, scientists at the National Institute of Allergy and Infectious Diseases (NIAID) and colleagues have found strong evidence that a genetic variation affecting immune system cells protects against heart disease. Details of the work, which also provides further evidence for the role of inflammation in heart disease, will appear in the April 15 issue of the Journal of Clinical Investigation.
"This work demonstrates how NIAIDs commitment to HIV/AIDS research can provide insights into the mechanisms of other diseases," says NIAID director Anthony S. Fauci, M.D. "The money spent on this research, so important to the millions of people around the world infected with HIV, also results in wider ranging benefits."
"The genetic variation we studied has a positive and protective effect against atherosclerosis. This effect is similar in magnitude, though opposite in value, to known negative risk factors such as diabetes and smoking. In other words, as bad as the negative risk factors are bad, this factor is good," says senior study author Philip M. Murphy, M.D. "In addition, the study may help explain part of the hereditary component of heart disease, establishing not only a genetic association but also giving evidence for a biological cause."

An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The discovery can make the encryption of satellite-based communications much more secure in the future.
A 15-member research team from the UK, Germany and Japan has developed a new method for generating and detecting quantum-entangled photons at a wavelength of...
Together with their colleagues from the University of Würzburg, physicists from the group of Professor Alexander Szameit at the University of Rostock have devised a “funnel” for photons. Their discovery was recently published in the renowned journal Science and holds great promise for novel ultra-sensitive detectors as well as innovative applications in telecommunications and information processing.
The quantum-optical properties of light and its interaction with matter has fascinated the Rostock professor Alexander Szameit since College.
Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies.
Stem cells can generate a variety of specific tissues and are increasingly used for clinical applications such as the replacement of bone or cartilage....
