X-ray laser converts plastic into diamonds, recreating Uranus rain

Scientists have turned plastic into diamonds. Using high-powered lasers, the team zapped samples of PET, the common material used in plastic bottles, to produce intense heat and pressure to form tiny diamonds that may naturally rain down on planets lik… Continue reading X-ray laser converts plastic into diamonds, recreating Uranus rain
