Matt Hancock criticises lockdown sceptics amid angry scenes in the Commons

It is impossible to have confidence in the government’s decision to overrule scientific adviceIn the weeks after Boris Johnson made his lockdown television address on 23 March, and as the UK’s infection and death rates rose shockingly higher, it was widely recognised that ministers had acted too slowly, and that the pandemic’s severity might have been lessened had they grasped the nettle sooner. Many ordinary people – perhaps especially those predisposed, like their prime minister, to look on the bright side – felt they had learned a hard lesson in the spring. Sometimes it pays to expect the worst.Yet here we are, after an appalling few months in which the UK topped European league tables of excess deaths. And with new infections running at 14,000 a day and hospital admissions and deaths once again climbing, there is no reason to believe that the government will avoid the same errors. Papers released on Monday night showed that on 21 September, ministers rejected a call by its Sage committee of scientific experts for a two-week “circuit breaker” lockdown to slow the virus’s transmission. That this was not disclosed until after Mr Johnson announced the new three-tier system suggests that he did not want to explain why. Continue reading...

UK wants to be deeply involved in next frontier of space exploration – the mission to MarsWhen the first female astronaut walks on the moon, more than half a century after Neil Armstrong took that historic first step, it will probably be heralded as a small step for a woman but a giant leap for womankind.But in the corridors of the UK Space Agency it will also be marked as the moment when Britain staked its claim to become a key player in the next frontier of space exploration – the mission to Mars.

What does a disease smell like? Humans might not have the answer, but if they could talk, dogs might be able to tell us. Able to sniff out a range of cancers and even malaria, canines’ extraordinary noses are now being put to the test on Covid-19. Nicola Davis hears from Prof Dominique Grandjean about exactly how you train dogs to smell a virus, and how this detection technique could be used in managing the spread of Covid-19 Continue reading...

Tedros Adhanom Ghebreyesus cites lack of understanding of virus and lasting health effects

Paul R Milgrom and Robert B Wilson awarded prize 26 years after game theory scholar John NashThe Nobel prize for economics was awarded on Monday to two US game theory specialists, 26 years after John Nash – the Princeton academic depicted by Russell Crowe in the 2001 film A Beautiful Mind – won for his groundbreaking work on the same subject.Americans Paul R Milgrom and Robert B Wilson won for the designs of mathematical models that promote “improvements to auction theory and inventions of new auction formats”, said Göran K Hansson, secretary-general of the Royal Swedish Academy of Sciences.

To make experimental antibodies affordable will cost billions. If they are shown to work, it will be money well spentCoronavirus – latest updatesSee all our coronavirus coverageWe all want a cure for Covid-19, but it won’t come in a single drug. Neither can we expect to escape this global crisis if treatments, tests or vaccines are not made available to those most vulnerable worldwide. There’s a long way yet to go.Robust research has shown that hydroxychloroquine, the drug once heavily promoted by Donald Trump, doesn’t work as a treatment. We wait in hope for the first vaccines but must be realistic: they may only provide partial protection, important as that will be. Now, as the US president pins his hopes on Regeneron’s antibody cocktail, it must be made clear: life can only return to normal with a range of clinically proven, effective treatments, tests and vaccines; the resilient health systems to deliver them; and the trust of the public.

Humour makes us more resilient, creative and resourceful – so is more important than ever during a pandemicFive years ago my brother awoke to dreadful news. His close friend was on a business trip in Mali, staying in the Radisson Blu hotel in Bamako. It had been stormed by Islamist militants and, ultimately, 170 hostages were taken, 20 killed. My brother’s friend, a Canadian, was on the seventh floor. Gun battles exploded directly below him. Escape wasn’t possible. He locked himself in the bathroom, texted his wife, his family – and my brother.“Things are a little tense inside the Radisson at the moment, Simon. Any English humour available?” He was looking for jokes. Continue reading...

The west has been wary of China’s rise as a scientific superpower, but the pandemic has made it impossible to ignore

In an extract from his new book, a colleague recalls a meal with the mathematician who shared the 2020 Nobel prize in physicsI had the pleasure of meeting Roger Penrose, the great mathematician from Oxford, when he was passing through Italy for the Festival of Science in Genoa. Penrose is a polyhedral intellectual. Readers know him for several books, among them the dense and wonderful The Road to Reality, a great panorama of contemporary physics and mathematics, a popular work that is not easy and that shines with intelligence and profundity on every page.Among his main contributions to our knowledge of the universe are theorems showing that Einstein’s theory implies that the universe we see originated from a big bang and black holes form generically. In the field of pure mathematics, he is better known for his study of “quasi-periodic” structures, tessellations composed of a few elements that can be repeated to infinity but that, however, are not periodic: they never repeat identically. They are also known as “quasi-crystals” and exist in nature, but they have also been used in fields that range from design of floor tiles to a children’s game devised by Penrose himself.
