We polled 52 leading UK epidemiologists, virologists and public health researchers to see when they think life will return to something resembling normality.

A majority expect mandatory face masks in shops and on public transport to remain in the UK until at least 2022.
On physical distancing guidelines, the majority of experts polled expected them to stay in place until 2022, with five people predicting that they will stay until 2023. One respondent thought that the guidance would always be necessary.
At the time of questioning, the UK government had promised to offer a vaccine to every adult by September. This goal has now been moved forward to the end of July. Among respondents, 27 said the UK government would meet its old target, 19 thought not.

How can we measure humanity's impact on the natural world? (1/5)

Human use now directly affects more than 70 per cent of Earth’s ice-free surface, with wilderness largely confined to a few areas of the Arctic, the Amazon rainforest, the Sahara desert and the Australian interior.
The acceleration of the rate of extinctions has been dramatic. The background or natural rate is 0.1 to 2 extinctions per million species per year. Data from the @iucn Red List of Threatened Species suggests a rate of 34 extinctions per million species per year now.
Since 1970, the global abundance of vertebrates has declined by 68 per cent, as measured by the Living Planet Index, produced by the @WWF in association with @OfficialZSL.

If you're getting a #COVID19 vaccine, there are a few things you can do to give your jab the best chance of working, based on research on other vaccinations. (Thread)
1. Avoid stress. Many studies have found that people experiencing stress have weaker antibody responses to vaccines, and positive mood on the day of vaccination is linked to a stronger response.
2. Sleep well. Studies report that people who get plenty of sleep on the nights before the vaccination have stronger antibody responses than those who sleep less.
