A different sort of driverless vehicle looks set to take to motorsport's tracks soon. Roborace is a new addition to the Formula E electric car racing series – an opportunity to promote autonomous driving and allow technology's best and brightest to hone their work. Lewis Hamilton et al may well be out of work a few years down the line.
Scaling up hydrogen production for fuel could be aided by the creation of 'Sweet Hydrogen' from sugar. Current methods of producing hydrogen, from heating fossil fuels and the electrolysis of water, are carbon-intensive and expensive respectively, but it is said that a sugary solution could alleviate both these problems.
One of plastic pollution's main offenders, polyethylene terephthalate (PET), could be tackled thanks to the discovery of a bacteria that breaks PET down using two enzymes and tendril-like threads. With only about four percent of the huge amount of PET produced each year recycled at present, it could be a discovery in the nick of time.
