At a stroke, Trump’s positive Covid diagnosis deprives him of at least 10 days’ worth of rallies and in-person fundraising, and then only if he’s very lucky. But it also serves as the mother of all distractions – from his taxes, his wife’s newly-disclosed indiscretions on children separated from their parents (“Give me a fucking break”), and from a debate performance that even loyalists are anxious to leave in the rear view mirror.
The news broke after midnight in a tweet. The betting odds on a Biden win shortened dramatically and futures markets swooned. Beyond that what we don’t know about the implications of Trump’s test is a much bigger category than what we do, but some important questions come quickly into focus:

Cambridge divests
Cambridge University said it will divest from fossil fuels by 2030 and aim to have only net zero companies in its portfolio – now worth £3.5 billion – by 2038. Vice-chancellor Stephen Toope said he wanted the university to be “leading not following” broader moves to cut carbon emissions. Activists welcomed the announcement but said it came five years too late. They also urged Cambridge to stop accepting money from oil and gas firms including Shell and BP. Last year it accepted £6 million from Shell for research into magnetic resonance imaging, which the university said would focus on clean energy tech but which can also analyse fossil fuel deposits. Next up: individual colleges’ endowments, worth another £3.5 billion.
Electric buses
China has 99 per cent of the world’s battery electric buses. As of last year it had more than 400,000 including 16,000 in Shenzhen alone. They’re starting to catch on elsewhere, including some of the smoggier parts of California – and now, at last, in the UK. Hats off to Ember, which at 5.30 am yesterday launched what it says is the country’s first all-electric intercity coach service between Dundee and Edinburgh. Tickets are £7.50 one-way with wifi, extended legroom and the good vibes that come with zero fumes, compared with £18.60 on a diesel Citylink bus. “Our business model is built on the premise this is possible if you go all in to be an electric only company,” Ember’s co-founder Keith Bradbury emailed me from the bus. “If car users knew they had a simple, well-priced, comfortable option that was also zero emissions then I think they would take it.”
Ember’s two Chinese-built buses cost £300,000 each and can do the 120-mile round trip on a single charge. Raising the money was a challenge. “Hardly anyone is interested in making it easy for bus/coach/hgv [heavy goods vehicles] to transition to battery electric,” Bradbury said. Note to government: isn’t that something we should fix?

Measuring Everest
Did a 2015 earthquake change the height of Everest? Last year a Nepalese expedition planted a GPS antenna on its summit to find out. This year a Chinese team followed suit. Results are due soon. In the meantime National Geographic has produced a completely fascinating piece on how hard it is to measure Everest in a way everyone can agree on. You have to get consensus on whether to measure the snow and ice on top and – harder – on where sea level is. As for that quake, it could have really shaken things up. Geologists reckon an earlier one, in 1934, lowered Everest by two feet.

Fast tests in Italy
Covid testing machines at Italian airports that give results in half an hour are going to be rolled out to schools, officials said this week. The technology (from South Korea) is not quite as reliable as the system in use in the UK that requires swabs to be sent to remote labs for molecular analysis, but Italy has decided to accept the risk of a small increase in false negatives in return for results in minutes rather than days. This is close to what Boris Johnson has called a moonshot plan for the future. Italy has it now, and its infection rate is one of the lowest in Europe.
French Muslim fears
Leaders of France’s six million-strong Muslim community, the biggest in western Europe, fear that a drive by President Macron to protect French values and eliminate separatist threats will target them unfairly. Macron will make a speech on his “anti-separatisms” initiative today and introduce legislation to back it up soon. There’s plenty of evidence that he is a genuine evangelist for secularism as part of a distinct French culture. He’s also up for re-election in 2022, when, as ever, the most formidable challenge to centrism will come from the hard right.
Thanks for reading, and do share this around.
