Human Deep Space Travel Are Associated To Health Risks For Exposure To GCR

Researchers found all three radiation types induced rapid and stable changes in DNA methylation but at distinct subsets of CpG sites affecting different chromatin compartments. Human deep space and planetary travel are limited by uncertainties regarding the health risks associated with exposure to galactic cosmic radiation (GCR) and in particular the high linear energy transfer (LET), heavy ion component. Here we assessed the impact of two high-LET ions 56Fe and 28Si, and low-LET X rays on genome-wide methylation patterns in human bronchial epithelial cells.

Research Finds Bio-marker For Autism

Autism diagnosis is slow and cumbersome, but new findings linking a hormone called vasopressin to social behaviour in monkeys and autism in people may change that. Low vasopressin in cerebrospinal fluid was related to less sociability in both species, indicating the hormone may be a biomarker for autism
