a note from the culture editor

Hello. I’m excited to announce that the New Scientist Photography Awards 2021 are now open for entries. We have launched the competition to celebrate extraordinary images that show how science and technology impact our lives and the world around us. This comes in many different forms, and so to inspire a diverse range of entries, we have settled on three award categories: The Natural World, Modern Life and Our Changing Environment. Our judging panel consists of naturalist and TV presenter Chris Packham, award-winning photographer Sue Flood and three members of the New Scientist team (including me). Together, we will decide the shortlisted entries, category winners and category runners-up. The overall competition winner will then be decided by public vote. And what is a photography competition without prizes? The overall winner will take…

taking out the junk

ALMOST every month, a new piece of research emerges linking diets high in processed “junk” foods with obesity and poor health. It isn’t yet clear if the relationship is causal, and if so, what the mechanisms behind it may be. But insights are starting to emerge from trials that compare diets that are based on either ultra-processed foods or wholefoods, yet are carefully matched for nutrients in all other ways (see page 36). The links need investigating as a matter of urgency. If these processed foods really do carry intrinsic health risks, it could mean that official advice about healthy eating has been aiming at the wrong target for decades. In almost all high-income countries, nutrition guidelines say the key to healthy eating is avoiding too much fat, salt and sugar. While…

g7 urged to donate now

AS SOME of the world’s wealthiest democratic nations prepare to meet in the UK at the G7 summit this week, pressure is mounting on high-income countries to donate more covid-19 vaccines to poorer parts of the globe. Ahead of the talks, the children’s charity UNICEF warned the G7 group that member nations need to supply vaccine doses to COVAX, the vaccine distribution plan set up by the World Health Organization (WHO), at a slow and steady rate throughout the year. It said that offloading a large batch at once would risk jabs going to waste, as some low-income countries may not have the facilities for administering so many doses in one go. In an open letter co-written by Jeremy Farrah, director of the Wellcome Trust, the charity also called for 20 per…

how to make travel safe

AS VACCINATION numbers continue to climb, high-income countries are beginning to journey back towards normality. That is also true of travel itself. On 1 June, seven EU countries set out on the long road back to freedom of movement, allowing unimpeded travel between them as long as arrivals can prove they are either immune to SARS-CoV-2 or uninfected. Many other countries are also inching back to business as usual. But the world of travel is still a long way from its destination. So how do we get back to where we started? And if you plan to travel abroad over the coming months, what do you need to know? The risks of returning to international travel as it was done before covid-19 are obvious: as people move about, so does the SARS-CoV-2…

how to go abroad and minimise your covid-19 risk

If you are desperate to go abroad, then what precautions should you take? “If you’re double vaccinated and you’re going to a low-risk area, I would take the view that you’re going to be pretty safe as long as you abide by the usual, sensible rules,” says Anthony Costello at University College London. The US Centers for Disease Control and Prevention (CDC) agrees. It advises travellers to low-risk countries to get fully vaccinated, wear a mask, avoid crowds, stay at least six feet (1.8 metres) from people they aren’t traveling with, wash their hands often and monitor their health for signs of illness. You should also take “low risk” with a pinch of salt. For instance, Portugal was on England’s green list, but on 8 June it moved to the amber list, meaning…
