How climate change is hitting Europe

Global warming is costing lives, deepening health inequality and driving the spread of diseases across Europe. A review of hundreds of studies has revealed that between 2013 and 2022, there were around 17 more heat-related deaths per 100,000 people per year than during the previous nine years. Warmer temperatures also mean that disease-carrying parasites including ticks and sandflies are spreading into more northern latitudes. “We really need some drastic action to be taken by European countries to help keep the European population, and also populations across the globe, safe from the health impacts of climate change,” says health researcher and study co-author Rachel Lowe.

Old genes could improve wheat

Genes from century-old wheat varieties could make the high-yielding but finicky modern crop more resistant to diseases or decrease its fertilizer needs. DNA sequencing of more than 800 wheat varieties held in a seed collection from the 1920s and 30s revealed that they contained twice as much genetic diversity as around 200 modern cultivars. “I could see that we were exploring a gold mine,” says geneticist and study co-author Shifeng Cheng. By planting the antique crops, the researchers could even pinpoint some of the genes responsible for traits such as nutritional content and stress tolerance.

Why bird flu is worse for some species

H5N1 avian influenza has killed millions of domestic and wild birds, as well as affecting many other animal species and spreading through US cattle. But few people are known to have been infected — only 15 worldwide, so far — and only one death, in 2022. And even among animals, some species seem to fare worse than others. There is still much to be done to understand how the virus affects different species, why people have so far been mostly spared and how that might change if the virus mutates. “There’s a lot we don’t understand,” says physician Tom Frieden, the former head of the US Centers for Disease Control and Prevention, who now heads an epidemic-prevention not-for-profit called Resolve to Save Lives. “I think we have to get over the ‘hope for the best and bury our head in the sand’ approach. Because it could be really bad.”

The science of election misinformation

Misinformation is undoubtedly being wielded in the swathe of elections occurring this year across the world. But it’s not clear what impact these falsehoods have. A body of research suggests that it is extremely difficult to persuade people to change their vote. But misinformation does not have to change minds to have an impact: it can mislead people about when and where to vote, or whether they should bother to vote at all. And just knowing that misinformation is out there — and believing it is influential — is enough to corrode trust in democracy, science and other structures.

How to build a career-development plan

Structured thinking about professional goals is common in industry and could also be effective for academics, says data scientist Tomasz Głowacki. Here are his steps for crafting an actionable development plan:

1. Ask your manager or mentor for input about your career aspirations. Be open about your strengths and weaknesses. Consider asking colleagues and students for (anonymous) feedback.

2. Have a clear idea of the end goal. Ask others about their career paths.

3. Identify the skills that you are missing and how to develop them, for example through training or working on specific projects.

Smarter Sustainable Development Goals

The United Nations’ Sustainable Development Goals (SDGs) offer a path to a better world — but none of the 17 goals, which include combating climate change and reducing inequality, is expected to be achieved by the UN’s 2030 deadline. The world should redouble its efforts, not abandon them, argues a group of researchers from institutions in Europe and the United States. They propose that the SDGs should all remain the same, and call for greater ambition: the goal to end poverty should include providing social protection for vulnerable people, for example.

Their advice is well timed, says a Nature editorial. Talks on a post-2030 future for the SDGs have not yet officially begun, but because adjustments to them cannot be made quickly, the earlier that discussions can begin, the better. And it’s perfect timing for the SDGs to be part of the discussion at an upcoming summit of world leaders convened by UN secretary-general António Guterres to draft a ‘Pact for the Future’.

Scientific photographer Steve Gschmeissner images tiny creatures, cells and viruses to show the public the world he sees through the microscope. “People say to me, ‘You’re looking at horrible things — cancer cells, viruses, bacteria — but you make them look attractive and beautiful. Is that a contradiction?’,” says Gschmeissner. “It sounds odd, but a cancer cell can produce a beautiful image. People who have cancer have said to me, ‘Seeing the image helps me relate to my cancer.’ Or, ‘I know what I’m up against.’” (Nature | 5 min read)

When geologist Rivoningo Khosa presented a poster titled ‘The geological period no one talks about: menstruation in the field’ some attendees had “quite entertaining” reactions, she says. Khosa is one of the scientists opening up conversations about menstruation to make fieldwork more inclusive. (Nature | 10 min read)
