The recent Great Recession was accompanied by a significant and sustained increase in major depression in US adults, according to a new study.

World's first genetic modification of human embryos reported: Experts consider ethics

Chinese scientists say they've genetically modified human embryos for the very first time. The team attempted to modify the gene responsible for beta-thalassaemia, a potentially fatal blood disorder, using a gene-editing technique known as CRISPR/Cas9. Show More Summary

Genome Reveals Secrets of Last Mammoths

The last of the woolly mammoths in Siberia died out about 10,000 years ago, but a smaller number living on Wrangel Island, off the coast of what is now Russia, managed to stick around for another 6,000 years. Researchers set out to investigate the two groups and the...

Fat tissue controls brain's response to food scarcity, helping regulate optimal amount of body fat for brain function

An enzyme secreted by the body's fat tissue controls energy levels in the brain, according to new research. The findings, in mice, underscore a role for the body's fat tissue in controlling the brain's response to food scarcity, and suggest there is an optimal amount of body fat for maximizing health and longevity.
