by Bianca Hermle, University of Tübingen Credit: Manu5, CC BY-SA 4.0 , via Wikimedia Commons The nervous system takes in sensory stimuli, processes them and triggers reactions such as muscle movements or pain sensations. A few years ago, a network in the brain was identified that is coupled with signals from the stomach and presumably influences...
by University of Pittsburgh Graphical abstract. Credit: Cell Reports (2022). DOI: 10.1016/j.celrep.2022.111319 The brain’s cerebral cortex is made up of distinct regions involved in myriad processes, from sensory perception to cognitive functions like memory, attention, and decision-making. University of Pittsburgh neuroscience researchers have found that the properties of one neuron subtype—somatostatin neurons—are specialized in different subregions of...
by Bill Hathaway, Yale University Graphical abstract. Credit: Neuron (2022). DOI: 10.1016/j.neuron.2022.08.011 Massive, repetitive stretches of DNA in the human genome may harbor hints about the onset of a rare, inherited neurodegenerative disorder called ataxia-telangiectasia as well as other related diseases, a new Yale School of Medicine study finds. The findings also point to possible directions for...

The American Cancer Society estimates that 44,130 Americans died of recurrent or metastatic breast cancer in 2021. Ten-year survival rates for patients fall from 93% to 27%...
The U.S. Food and Drug Administration has approved Xenpozyme (olipudase alfa) for pediatric and adult patients with acid sphingomyelinase deficiency (ASMD), a rare genetic disease. ASMD is caused by the lack of an enzyme needed to break down the complex lipid sphingomyelin, which can accumulate in the liver, spleen, lung, and brain. Xenpozyme infusions provide enzyme...
