Study of Worms Reveals ‘Selfish Genes’ That Encode A Toxin – and Its Antidote

A UCLA study has found that a common strain of Caenorhabditis elegans — a type of roundworm frequently used in laboratory research on neural development — has a pair of genes that encode both a poison and its antidote. The new research also revealed that if worms with the two genes mate with wild strains of C. elegans that don’t have both genes,…

Project to Map Human Brain From Womb to Birth Releases Stunning Images

A landmark project to map the wiring of the human brain from womb to birth has released thousands of images that will help scientists unravel how conditions such as autism, cerebral palsy and attention deficit disorders arise in the brain. The first tranche of images come from 40 newborn babies who were scanned in their sleep to produce stunning high-resolution…

The Genes and Neural Circuits Behind Autism’s Impaired Sociability

Researchers at Beth Israel Deaconess Medical Center (BIDMC) have gained new insight into the genetic and neuronal circuit mechanisms that may contribute to impaired sociability in some forms of Autism Spectrum Disorder. Led by Matthew P. Anderson, MD, PhD, Director of Neuropathology at BIDMC, the scientists determined how a gene linked to one common form of autism works in a…

Zika-linked Birth Defects More Extensive Than Previously Thought, UCLA-led Research Finds

New UCLA-led research finds that Zika-linked abnormalities that occur in human fetuses are more extensive — and severe — than previously thought, with 46 percent of 125 pregnancies among Zika-infected women resulting in birth defects in newborns or ending in fetal death. The study, published in the New England Journal of Medicine, suggests that damage during fetal development from the…

Our Brains Have A Basic Algorithm That Enables Our Intelligence, Scientists Say

Our brains have a basic algorithm that enables us to not just recognize a traditional Thanksgiving meal, but the intelligence to ponder the broader implications of a bountiful harvest as well as good family and friends. “A relatively simple mathematical logic underlies our complex brain computations,” said Dr. Joe Z. Tsien, neuroscientist at the Medical College of Georgia at Augusta University,…
