He started a company that derives building materials from cannabis. Hempcrete is made by combining the woody, balsa-like interior of the Cannabis sativa plant with lime and water. It provides natural insulation that is airtight yet breathable and flexible; free from toxins, mold, and pests; and virtually fireproof. — The New York Times

  • Australian researchers have designed a zebra-striped wetsuit to scare sharks away.

But playing games all day isn't exactly good for you either. These sedentary activities can lead to an increase in anxiety. — Upworthy
