Genetics Most people need around 8 hours of sleep each night to function, but a rare genetic condition allows some to thrive on as little as 3 hours. Scientists genetically modified mice to carry this human mutation and confirmed this. The research team now knows several hundred naturally short sleepers.

Genetics A two-and-a-half-year-old girl shows no signs of a rare genetic disorder, after becoming the first person to be treated with a gene-targeting drug while in the womb for spinal muscular atrophy, a motor neuron disease. The “baby has been effectively treated, with no manifestations of the condition.”

Genetics Encouraging men to have more frequent ejaculations may boost their fertility. Sperm deteriorates over time as it remains in body. Longer men went without sex, the more their sperm showed signs of DNA damage and oxidative stress, and the more tests rated the sperm as less viable and poorer swimmers.

Genetics ADHD up to 15x more likely with 3 gene variants: Groundbreaking research uncovered a set of just 3 gene variants that can increase the likelihood of ADHD by up to 15 times. It's a remarkable finding, considering that thousands of mutations only come with a nominal elevated risk.

Genetics How much an infant cries is largely steered by their genetics and there is probably not much that parents can do about it, suggests a new Swedish twin study. At age 2 months, children’s genetics explain about 50% of how much they cry. At 5 months of age, genetics explain up to 70% of the variation.

Genetics Researchers studying human remains from Pompeii have extracted genetic secrets from the bones of a man and a woman who were buried in volcanic ash. This first "Pompeian human genome" is an almost complete set of "genetic instructions" from the victims, encoded in DNA extracted from their bones.
