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
Scientists have developed a new type of smart bandage that can signal the type of bacterial infection it’s protecting, just like a traffic light, as well as release the right type of drugs on demand. The researchers behind the design hope it could help to fight back against antibiotic resistance, as well as heal
Scientists continue to push the boundaries of what cameras are capable of – like a newly developed phase-sensitive compressed ultrafast photography (pCUP) device, which is capable of snapping an impressive one trillion frames every second. That’s mind-boggling, but it’s not a record, because some of the same researchers developed a camera that can take
Could a massive barrier erected in the ocean shield New York from the devastation of superstorm surges like Hurricane Sandy in 2012? The truth is, nobody knows for sure, but a giant sea wall is nonetheless one serious proposal being looked at in a long-term research project designed to prevent a repeat of the deaths
Scientists at the University of Colorado, Boulder have created what The New York Times calls a “living concrete”, teeming with photosynthetic bacteria, that can grow itself and regenerate itself – much like a living organism. The concrete is a mixture of gelatin, sand, and cyanobacteria that cools similarly to Jell-O, the Times reports. The resulting structure was able to regenerate itself
In another lifetime, if they had been allowed to follow their natural development, the stem cells taken from embryonic frogs would have turned into skin and heart tissue within living, breathing animals. Instead, in configurations designed by algorithms and constructed by humans, those cells have been assembled into something new: the first-ever robots constructed
Scientists may have solved one of the great Leonardo da Vinci painting mysteries – why the glass orb in the Salvator Mundi painting (dated to around 1500 CE) shows no signs of the refraction and reflection of light that might be expected. The answer, according to computer models run by a team from the
To protect its hosts, Airbnb is now using an AI-powered tool to scan the internet for clues that a guest might not be a reliable customer. According to patent documents reviewed by the Evening Standard, the tool takes into account everything from a user’s criminal record to their social media posts to rate their likelihood
Something strange has been happening in eastern Colorado at night. Since the week of Christmas, giant drones measuring up to 6 feet (1.8 metres) across have been spotted in the sky at night, sometimes in swarms as large as 30. The Denver Post first reported these mysterious drone sightings in northeastern Colorado on December
The future had arrived. There was only one problem: it was deafening. In the 1960s, the development of supersonic passenger aircraft promised to revolutionise the concept of international travel, teasing flights from New York to Paris in under 3.5 hours – less than half the duration of conventional subsonic jaunts. With the famed Concorde,
In March, Chinese researchers predicted that the nation’s HL-2M tokamak – a device designed to replicate nuclear fusion, the same reaction that powers the Sun – would be built before the end of 2019. No word yet on whether that’s still the case, but in November, Duan Xuru, one of the scientists working on
The world’s first fully electric commercial aircraft took its inaugural test flight on Tuesday, taking off from the Canadian city of Vancouver and offering hope that airlines may one day end their polluting emissions. “This proves that commercial aviation in all-electric form can work,” said Roei Ganzarski, chief executive of Seattle-based engineering firm magniX.
Scientists said Wednesday they have come up with an environmentally-friendly method that uses artificial sunlight to transform plastic into power-generating chemicals, as countries worldwide battle to reduce waste. Huge quantities of plastic have piled up on land and been dumped in the sea across the world, with many nations facing criticism for failing to
Quantum computing has the potential to revolutionise the processing power at our fingertips, but for the moment a lot of it is just potential. Researchers have been uncertain on whether we’ll ever be able to harness quantum computing in a practical, affordable, realistic way. But we might have an exciting new lead. Two new
