Spinning a revolution: the physicists turning wood into clothes
You might not realize this, but the world’s fashion and clothing industry causes 10% of global carbon-dioxide emissions – more than international flights and maritime shipping combined. Fortunately, Finnish physicist Janne Poranen is on the case: he’s co-founded a company called Spinnova that is transforming cellulose from wood into textile fibre without using any chemicals. As this month's cover feature explains, the firm has a pilot production facility, with H&M and Adidas already taking an interest. Also in this issue: explore the latest on high-temperature superconductors, magnets that don’t need rare earths and the joys of switching your research field.
