DNA Tests Provide a Look at the Global Scale of Genetic History

DNA tests can reveal fascinating things about an individual’s genetic history, including their ancestral roots and even their rare medical conditions.

A recent study published in Science has highlighted another interesting use of DNA tests. Researchers have pinpointed, dated, and characterized historical genetic mixing, creating a global genetic map that gives us deeper insight into how past populations moved and changed — and how notable historic events shaped our genes.

DNA Robots Can Sort Through Our Molecules

 

In a study published in Science, researchers at the California Institute of Technology designed a group of DNA robots. They are called DNA robots not because they have “bodies”, “hands”, “arms”, and “feet,” but because they perform mechanicalĀ tasks at the nanometer scale. The robots’ current goal is to work together to find and collect fluorescent molecules. Continue reading “DNA Robots Can Sort Through Our Molecules” »

DNA May Actually Contain Addiction Gene

Researchers have identified another gene that may influence an individual’s risk of opioid dependence. This adds further evidence that genetic factors play a crucial role in determining who develops an addiction. Continue reading “DNA May Actually Contain Addiction Gene” »
