Aberrant fear-memory processing in the brain is thought to underlie anxiety disorders, which affect hundreds of millions of people worldwide. The neurobiological mechanisms underlying these disorders remain poorly understood, but recent…

Mathematical method builds synthetic hearts to identify how heart shape could be linked to disease

Researchers from King’s College London have created 3D replicas of full-sized healthy adult hearts from Computed Tomography (CT) images and analyzed how cardiac shape relates to function. Published today in PLOS Computational Biology, the study also includes 1000 new synthetic hearts that have been made open access allowing researchers to download and use them…

Understanding how DNA repairs itself may lead to better cancer treatment

From cancer treatment to sunlight, radiation and toxins can severely damage DNA in both harmful and healthy cells. While the body has evolved to efficiently treat and restore damaged cells, the mechanisms that allow this natural repair remain misunderstood. In a new study, Northwestern University researchers have used cryogenic electron microscopy (cryo-EM) to visualize this…

Genetic ancestry versus race can provide specific, targeted insights to predict and treat many diseases

The complex patterns of genetic ancestry uncovered from genomic data in health care systems can provide valuable insights into both genetic and environmental factors underlying many common and rare diseases–insights that are far more targeted and specific than those derived from traditional ethnic or racial labels like Hispanic or Black, according to a team of…
