Hotspot in the genome may drive psychosis in schizophrenia and bipolar disorder
A cluster of epigenetic marks in an enhancer at IGF2 could enhance dopamine synthesis associated with psychosis in schizophrenia and bipolar disorder. The findings may help in devising more effective treatments and screening strategies for both disorders.... Read More...
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. ...
