Solar panels are fantastic pieces of technology, but we need to work out how to make them even more efficient – and last year, scientists solved a 40-year-old mystery around one of the key obstacles to increased efficiency. The 2019 study outlined a material defect in silicon used to produce solar cells that has

Have you ever used a public charging station to charge your mobile phone when it runs out of battery? If so, watch out for “juice jacking”. Cybercriminals are on the prowl to infect your mobile devices such as smartphones and tablet computers and access your personal data, or install malware while you charge them.
Released in 1896, L’arrivée d’un train en gare de La Ciotat is one of the earliest examples of movie-making we have – the 50-second silent short, which shows a mail train pulling into La Ciotat station, seems humdrum by today’s standards, but would have wowed 19th century crowds seeing moving pictures for the first time.
A team of researchers at the French National Institute of Health and Medical Research in Bordeaux have grown yarn from human skin cells that they call a “human textile” – and they say it could be used by surgeons to close wounds or assemble implantable skin grafts. “These human textiles offer a unique level
As beneficial as current solar panel technology has been in our quest to switch to renewable energy, such panels can’t generate electricity at night. Now, new research suggests it could be possible to design panels that can operate around the clock. Under optimum conditions, at night these specially designed photovoltaic cells could generate a
