Why Europe is once again the epicentre of the pandemic
LAST week Europe registered 1.5m new cases of Covid-19 – a record – making it once again the centre of the pandemic. The UK is not exempt, and England will enter a new lockdown from Thursday 5 November. From the outside, it might seem the continent is in the grip of a second wave that is…

On the rise and rise of Chinese science
IT started badly, with gag orders, cover-ups and ignored offers of help from overseas, but then the Chinese government seized the narrative. It reined in the burgeoning epidemic of Covid-19 at home, and started exporting its rapidly accumulating scientific knowledge of the disease to the rest of the world. Chinese science has often been marginalised…

The genetic roots of Covid-19
A significant proportion of patients who develop life-threatening forms of Covid-19 have genetic or immunological defects that impair their ability to fight the virus, research has found… This article first appeared in The Guardian on 24 September 2020. To continue reading, click here.

SARS-CoV-2 is changing at a glacial pace
SCIENTISTS have had eyes on Sars-CoV-2, the virus that causes Covid-19, since the beginning of this pandemic. They can see it is evolving, but it is happening at a glacial pace compared with two other viruses with pandemic potential: those that cause flu and Aids. That is good news for efforts to develop vaccines and treatments,…

The dirty vaccine race
TO begin with, it felt like a sleek performance from a well-honed relay team. On 11 January, only 10 days after reporting a new respiratory disease, the Chinese published the genome sequence of the virus that causes it. Researchers around the world set to work building vaccines against Covid-19, as the disease became known, and…

On the origins of smallpox
THE death date of smallpox is clear. After killing more than 300 million people in the twentieth century, it claimed its last victim in 1978; two years later, on 8 May 1980, the World Health Assembly declared that the variola virus, which causes smallpox, had been eradicated. But the origins of this devastating virus are…

On plague memory (again)
RUMINATING on why the 1918 flu pandemic wasn’t better remembered, the African historian Terence Ranger concluded in the early 2000s that the story wasn’t being told right. The vast majority of the victims—50 million of them at a conservative count—perished in a mere 13 weeks at the tail end of 1918, all over the globe.…

‘It’s not over’: intimate diaries from the eye of the UK’s coronavirus storm
WHEN the Oxford team working on a Covid-19 vaccine first started holding weekly catchups in early February, Christina Dold, a 35-year-old senior postdoctoral researcher, jokingly referred to them as “Cobra” meetings. But it was in one of these early sessions that she found out how many volunteers they would be immunising daily, once the vaccine…

Drugs, money and misleading evidence
IN the race to find treatments and a vaccine for COVID-19, it’s more essential than ever that society can trust drug companies seeking regulatory approval. The Illusion of Evidence-Based Medicine is the latest in a long line of books that caution us not to hold out much hope… This article was first published in Nature on…

Poison centre cases rise under Covid-19
THE official US advice has been to disinfect high-touch surfaces to minimise the spread of Covid-19. Taking that advice to the extreme, Lisa filled a sink with a mixture of 10% bleach solution, vinegar and hot water and soaked her vegetables and other food in it. Soon, she noticed a powerful odour of chlorine in…
