A new study shows connections between genetics, biomarkers in the blood, and mental disorders - opening new avenues to understand the causes of mental illness and find new treatments.
A billion-year-old ‘hydrogen economy’ in the frozen soil of Antarctica provides bacteria with energy, water, and the carbon that makes up their bodies.
David Julius, one of the two recipients of the 2021 medicine Nobel Prize, used the active component in chile peppers to study how the brain senses heat.
