For Neurons, Where They Begin Isn’t Necessarily Where They End

Scientists at UC San Diego School of Medicine and Rady Children’s Institute of Genomic Medicine describe novel methods for inferring the movement of human brain cells during fetal development by studying healthy adult individuals who have recently passed away from natural causes.

Gene Mutation Weakens Virus-Fighting Protein in the Gut Causing Rare Inflammatory Bowel Disease

Johns Hopkins Medicine researchers, in collaboration with national and international researchers, have identified a genetic mutation in a small number of children with a rare type of inflammatory bowel disease. The discovery of the mutation, which weakens the activity of a protein linked to how the immune system fights viruses in the gut, may help researchers pinpoint the cause of more common bowel diseases, investigators say.

Researchers Discover New Variant of COVID-19 Virus in Columbus, Ohio

Scientists have discovered a new variant of SARS-Cov-2, the virus that causes COVID-19. It carries a mutation identical to the U.K. strain, but it likely arose in a virus strain already in the U.S. The researchers also report the evolution of another U.S. strain that acquired three other gene mutations not previously seen together in SARS-CoV2.

Mount Sinai Researchers Uncover New Molecular Drivers of Parkinson’s Disease

New Approach Will Lead to a Better Understanding of Most Cases
