Scientists discover a new strain of HIV for the first time since 2000

Scientists find new strain of HIV for the first time since 2000 – and they say the discovery is a step toward ending the pandemic by including it in testing, treatment and potential vaccines Scientists at Abbott Labs have confirmed that a strain of HIV that infected three people in the Democratic Republic of Congo is a new variety of […]

Gut instincts: Researchers discover first clues on how gut health influences brain health

New cellular and molecular processes underlying communication between gut microbes and brain cells have been described for the first time by scientists at Weill Cornell Medicine and Cornell’s Ithaca campus. Over the last two decades, scientists have observed a clear link between autoimmune disorders and a variety of psychiatric conditions. For example, people with autoimmune disorders such as inflammatory bowel […]

Cell family trees tracked to discover their role in tissue scarring and liver disease

Researchers have discovered that a key cell type involved in liver injury and cancer consists of two cellular families with different origins and functions. The research by academics from the Universities of Edinburgh and Bristol and funded by the Wellcome Trust and Medical Research Council, is published today [Tuesday 15 October] in Nature Communications. The distinguishing feature of these families—whether […]

Researchers discover how the sun damages our skin

Researchers at Binghamton University, State University of New York have discovered the mechanism through which ultraviolet radiation, given off by the sun, damages our skin. What kind of ultraviolet radiation is the worst for our skin? And how exactly does the sun damage it? Those two questions are at the heart of a new study by Zachary W. Lipsky, a biomedical […]

Scientists discover complex connections between social dynamics and diseases

Large gatherings—from music festivals to religious pilgrimages to sporting events—have long been known to increase risks of infectious disease outbreaks. Now results from an NSF-funded study led by UC Berkeley researchers associate even small-scale community gatherings with increased transmission of diarrheal diseases. The results are published in the American Journal of Epidemiology. Gatherings at events can create environmental and social […]

Researchers discover how tumor-killing immune cells attack lymphomas in living mice

In a study that will be published April 1 in the Journal of Experimental Medicine, researchers from the Institut Pasteur and INSERM reveal that chimeric antigen receptor (CAR) T cells can induce tumor regression by directly targeting and killing cancer cells, uncovering new details of how these immune cells work and how their effectiveness could be improved in the treatment […]

Researchers discover serotonin can regulate gene expression inside neurons

The brain chemical serotonin, a neurotransmitter long known for its role in passing signals between neurons in the brain, can also regulate expression of genes within neurons in an unexpected way, according to research conducted by neuroscientists at the Icahn School of Medicine at Mount Sinai and published on March 13 in the journal Nature. The discovery may help scientists […]

Researchers discover clues to brain differences between males and females

Researchers at the University of Maryland School of Medicine have discovered a mechanism for how androgens—male sex steroids—sculpt brain development. The research, conducted by Margaret M. McCarthy, Ph.D., who Chairs the Department of Pharmacology, could ultimately help researchers understand behavioral development differences between males and females. The research, published in Neuron, discovered a mechanism for how androgens, male sex steroids, […]

Researchers discover how sleep can fight infection

Researchers in Germany have discovered why sleep can sometimes be the best medicine. Sleep improves the potential ability of some of the body’s immune cells to attach to their targets, according to a new study that will be published February 12 in the Journal of Experimental Medicine. The study, led by Stoyan Dimitrov and Luciana Besedovsky at the University of […]

Researchers discover the brain cells that make pain unpleasant

If you step on a tack, neurons in your brain will register two things: that there’s a piercing physical sensation in your foot, and that it’s not pleasant. Now, a team of scientists at Stanford University has identified a bundle of brain cells in mice responsible for the latter—that is, the negative emotions of pain. Pain research has traditionally focused […]
