Tracing the flow of cerebrospinal fluid
AMERICAN PHYSICAL SOCIETY VIRTUAL MEETING (CST), November 22, 2020 — Swelling is one of the most dangerous and immediate consequences of a brain injury or stroke. Doctors have long known about the dangers of swelling, which has traditionally been blamed on ruptured blood vessels. New research suggests the brain’s other plumbing system, the one that circulates cerebrospinal...
New prediction algorithm identifies previously undetected cancer driver genes
A new study, led by U.S. National Science Foundation-funded researchers at the University of California, Irvine, has deepened the understanding of epigenetic mechanisms in tumorigenesis and revealed a previously undetected repertoire of cancer driver genes. The results were published in Science Advances. Using a new prediction algorithm, called DORGE (Discovery of Oncogenes and tumour suppressor genes using Genetic and Epigenetic...
Cartographers of the brain
UCI’s Center for Neural Circuit Mapping is redrawing our understanding of mechanisms underlying several common disorders. Thanks to Xiangmin Xu and his team at the UCI School of Medicine’s Center for Neural Circuit Mapping, lazy eye, Alzheimer’s and other neurological diseases could become a thing of the past. Opened earlier this year, the unit focuses...
New Phase of Microbiome Research
Trillions of microbes—bacteria, viruses, fungi—colonize in our bodies, and their genome of genetic instructions work alongside ours. Over the past two decades of microbiome research, scientists have accumulated a veritable field guide to these microbes that live on, in and around us, and they have begun to understand the integral role microbes play in our digestion...
‘CYTOKINE STORMS’ AREN’T BEHIND MOST COVID-19 LUNG FAILURES
Inflammation from an out-of-control immune response doesn’t appear to be the main problem for the vast majority of hospitalized COVID-19 patients, a new study shows. The turning point for people with COVID-19 typically comes in the second week of symptoms. As most people begin to recover, a few others find it increasingly difficult to breathe...

Memories of past events retain remarkable fidelity even as we age
by Association for Psychological Science Scientists studying the complex relationship between aging and memory have found that in a controlled experiment, people can remember the details about past events with a surprising 94% accuracy, even accounting for age. These results, published in the journal Psychological Science, suggest that the stories we tell about past events are accurate,...
