Unapproved graft
Heinrich Heine University Düsseldorf estimates that automation stopped 275,000 manufacturing jobs being created between 1994 and 2014. However, this was offset by posts created in other sectors, particularly the service industry. It’s not all good news. Robots have tended to reduce wages for those in lower and mediumskilled manufacturing jobs, the study found. Südekum says it might be a good idea to ensure the benefits of automation are shared by all workers, for example by raising taxes on firms that replace workers with robots.
EXPERIMENTAL implants made at University College London were used on patients without approval, an inquiry has found. The implants included an artificial windpipe, a synthetic tear duct and an arterial graft. The inquiry was at the request of UCL, prompted by its relationship with Paolo Macchiarini, a surgeon who had been an honorary professor there. He has been at the centre of a scandal in which six of eight people who received synthetic windpipes died. The inquiry highlighted several

cases, including one involving a man in Iceland who had a trachea tumour. Macchiarini decided to remove the tumour and replace the affected segment of trachea with a synthetic graft provided by Alexander Seifalian, then at UCL. The inquiry found that Seifalian’s laboratory wasn’t licensed to make clinical-grade devices and didn’t request permission to use them in this way. But Seifalian says his job was to do the basic research. “The implantation was the job of the surgeon, who requires getting ethical approval and [regulatory] approval. This was not my job.”
Grass-fed beef is bad for climate

ELON MUSK is dreaming big. PRINCE CHARLES is wrong to support grass-fed beef. The idea that beef On 29 September, he announced from cows on pastures is good for plans for a huge new SpaceX the environment, allowing us to eat rocket that he says will go to Mars as much as we want, doesn’t add up. in 2022 and may even provide “Though it would be nice if the speedy trips around Earth. pro-grazers were right, they aren’t,” The rocket, which Musk calls says Tara Garnett of the University the BFR – the first and last letters of Oxford. “We cannot eat as much stand for “big” and “rocket” – is meat as we like and save the planet.” smaller than the now-scrapped A typical cow releases design he revealed last year, 100 kilograms of methane a year, but still more powerful than any produced by the microorganisms in other rockets planned. its gut, and there are about a billion Musk said the BFR will replace cows worldwide. Since methane is all of SpaceX’s other vehicles: a greenhouse gas, this exacerbates the Falcon 9 and Falcon 9 Heavy global warming. Also, destroying rockets and the Dragon capsule. forests to feed cows emits The BFR’s first tasks will be greenhouse gases too. satellite launches and bringing But a counter-view has gained cargo and crew to the ISS. Then, Musk said, it will make its way to the moon. The rocket will have 40 cabins that could each hold up to five or six people, along with a solar storm shelter and entertainment area. After the initial 2022 Mars mission, Musk plans to send four BFRs to the Red Planet in 2024. Two will be crewed; they will mine water and extract carbon dioxide from the atmosphere to make fuel for return missions. Musk claimed the rockets might one day be used to shuttle passengers from New York City to –Delicious but harmful– Shanghai in 39 minutes.
currency. Ecologist and livestock farmer Allan Savory claims pasture plants capture carbon from the air. Pastures should also reduce our need for food crops grown on land that releases carbon when ploughed. Garnett and her team calculated how greenhouse gases flow through pastures. They found that carbon capture offsets at best 20 to 60 per cent of grazing emissions. “And the carbon capture stops after a few decades,” says Garnett. “The cattle continue to belch methane.” The findings are published in a report, Grazed and Confused? “It asks, if we are to eat meat, is there a better way to grow it?” says Tim Benton at the University of Leeds, UK. “The answer is: not really.”
Keys to secure email After the 2016 Hillary Clinton campaign hacks, Google looked into new ways to secure online accounts. This month, high-profile Gmail users – politicians and others whose accounts are likely to attract attacks – will be offered physical security keys instead of two-factor authentication, which can be hackable in certain situations.
Free ride Do you have an electric car? From next year, you may be able to start driving it for free in the UK. Energy companies will pay electric vehicle owners to charge or drain their car battery at certain times, as part of a scheme to help power grids manage supplies from clean energy sources. It could slash the overall cost of charging the battery to nothing.
Vitamin cuts asthma Vitamin D supplements may lower the risk of asthma attacks. An analysis of 955 people found that taking the pills is linked to a 30 per cent lower incidence of asthma attacks requiring steroid treatment, and a halving in ones requiring hospitalisation (The Lancet Respiratory Medicine, DOI: 10.1016/ S2213-2600(17)30346-6).
Dominica to be resilient The hurricane-ravaged island of Dominica wants to transform itself into “the first climate-resilient nation of the climate change era”. The island suffered extensive damage after being directly hit by Maria, a category 5 storm. The rebuilding programme mustn’t recreate the same vulnerabilities, the prime minister said on 2 October.
We go back a long way Our species is older than we thought. A genetic analysis of seven Stone Age and Iron Age people from Africa suggests that Homo sapiens was present at least 260,000 years ago, supporting recent fossil finds (Science, doi.org/cdtn).
