Credit: NIAID A study of HIV-positive black and Latino men who have sex with men finds the use of methamphetamine combined with intimate partner violence boosted the activity of genes that regulate the body’s inflammatory and antiviral functions. The combination may lead to exhaustion...
by University of Virginia Credit: CC0 Public Domain University of Virginia School of Medicine researchers have developed a noninvasive way to remove faulty brain circuits that could allow doctors to treat debilitating neurological diseases without the need for conventional brain surgery. The UVA team, together with colleagues at Stanford University, indicate that the approach, if...

by Massachusetts Institute of Technology Credit: Pixabay/CC0 Public Domain A common strategy to make vaccines more powerful is to deliver them along with an adjuvant—a compound that stimulates the immune system to produce a stronger response. Researchers from MIT, the La Jolla Institute for Immunology, and other institutions have now designed a new nanoparticle adjuvant that...
by Weill Cornell Medical College Credit: Pixabay/CC0 Public Domain Pound for pound, the brain consumes vastly more energy than other organs, and, puzzlingly, it remains a fuel-guzzler even when its neurons are not firing signals called neurotransmitters to each other. Now researchers at Weill Cornell Medicine have found that the process of packaging neurotransmitters may be...
Just as convincing images of cats can be created using artificial intelligence, new proteins can now be made using similar tools. In a report in Nature, researchers describe the development of a neural network that “hallucinates” proteins with new, stable structures. Proteins, which are string-like molecules found in every cell, spontaneously fold into intricate three-dimensional shapes....
Small fiber neuropathy occurs as a result of damage to the small fibers of the peripheral nervous system. These small fibers detect pain, heat, and itching sensations in the skin. They also regulate the autonomic functions of the cardiovascular system and the gastrointestinal tract. Damage to the peripheral nervous system that affects the small fibers...
