Gene linked to autism undergoes changes in men’s sperm after cannabis use

Marijuana use alters a gene associated with autism in sperm. Hypomethylation was identified in the DLGAP2 gene in the sperm of male rats exposed to THC. The hypomethylated state was also detected in the forebrains of their offspring. Further research is needed to establish if there is a definitive link between paternal cannabis use and ASD in humans.

NASA’s Landmark Twins Study Reveals Resilience of Human Body in Space

NASA scientists have published the results of the Kelly Twin Study, which revealed how the body adapts to life in space, compared to life on Earth. The findings revealed that, in space, telomeres are unexpectedly longer, the immune system responds appropriately, and variability in gene expression alters. Read More

Cannabis Exposure Alters Genetic Profile of Sperm

THC exposure targets genes in two major cellular pathways and alters DNA methylation, a new study reports. Researchers say that wile cannabis triggers structural and regulatory changes in the DNA of users' sperm, they do not know yet whether the changes are passed down to the offspring and what effects that could have.
