Epigenetic mapping provides deeper insight into leukemia

Researchers at Karolinska Institutet in Sweden and Kyoto University in Japan have identified new subgroups of the blood cancer acute myeloid leukemia. The study, published in the journal Nature, shows that changes in the regulation of genes within cells can help explain variation

New mechanism explains how nerve cells form one long output branch

DZNE researchers have uncovered a mechanism that determines why a neuron usually forms a single, long extension called an "axon"—a phenomenon that is fundamental to how our brain functions. Contrary to the common view that external cues drive axon formation, the team of scientist

Disordered collagen may help explain hip fractures beyond bone density, X-rays reveal

Fractures of the femoral neck are not simply due to insufficient bone density. Also significant is their nanostructure—the orientation of the collagen fibers that make up bones, according to research conducted by scientists at the Paul Scherrer Institute PSI using a new X-ray tec

New study provides first evidence of dopamine system injury in the brain of long COVID pat

A new brain imaging study led by researchers at the Center for Addiction and Mental Health (CAMH), published in eBioMedicine, provides the strongest evidence to date that long COVID is associated with injury to dopamine-releasing neurons in the brain—a finding that may explain sy

Demystifying the molecular mechanisms of general anesthesia

Researchers at Weill Cornell Medicine and Birkbeck, University of London, have identified a site where a commonly used anesthetic binds to sodium ion channels, revealing a molecular mechanism that may explain how these drugs dampen communication between neurons. Ion channels are

Researchers reveal immune mechanisms that drive development of rare allergic stomach disea

Researchers at Tel Aviv University have developed one of the first experimental models that faithfully reproduces eosinophilic gastritis (EoG), a rare but increasingly recognized allergic disease of the stomach. Using this model, they identified the immune pathways responsible fo

Why some people are more prone to negative emotions than others

Why are some people particularly prone to anxiety, worry or stress, while others remain more composed? An international study led by the Central Institute of Mental Health (CIMH) shows that the amygdala—previously considered central to these processes—apparently does not explain

Genetic safeguard protects the female heart—and what happens when it's lost

Men and women are not born with the same risk of heart disease, and for decades scientists have struggled to explain why. A new study from the University of North Carolina at Chapel Hill, published in Genes & Development, offers an answer: The female heart depends on a molecular
