Summary

Caffeine-motivated researchers find that pour height may be the key to a perfect cup of coffee. A new study of plastics finds that less than 10 percent of such products are made with recycled materials. And once the plastics are used, only 28 percent of them make it to the sorting stage—and only half of that plastic is actually recycled. Data from the Hubble Telescope show how a day on Uranus lasts longer than previously thought. Plus, we discuss how scientists thought dinosaurs were in decline even before their mass extinction—until now.
