Declaring a global planetary emergency, improving sub-volcanic imaging to predict eruptions and developing artificial intelligence that works for humans are some of the urgent actions and research that experts in different fields want to see in 2020.
The most powerful source of misperceptions about important issues such as immigration and climate change are false beliefs rooted in people’s political or social preferences, but having people who question authority is also important for a society, according to Professor Jason Reifler, a political scientist at the University of Exeter, UK.
Innovative ways of supporting undocumented migrants so that they can access vital health, social and emergency services are required so that European countries can properly assist these vulnerable people.
It is used as a fertiliser to help crops grow, burned as a fuel for heat, and is even used as a building material. But exactly when and how humans began using dung is a mystery that is now starting to be unravelled by researchers.
Around the world there are 10 wars being fought, according to recent figures. That covers humanity’s most deadly clashes, but the figure rises to 49 if you count those state-based conflicts where ‘only’ 1,000 people or fewer have been killed in the past year. The captain’s share of all this fighting happens in cities.
The rise of right-wing populism is being fuelled by polarisation in society that we must address without resorting to the claim of moral superiority, or protest voters will become the permanent supporters of these new parties, says Wolfgang Merkel, director of the Democracy and Democratisation research department at the WZB Berlin Social Science Center, Germany, and professor of political science at the Humboldt University of Berlin.
Domestic dogs come in all shapes and sizes, but the animals we now regard as man’s best friend may have originated from just two populations of wolves, research suggests. The findings, along with studies on other domesticated animals, are providing new insights into how our ancestors' lives and movements transformed these creatures forever.
Fake news has already fanned the flames of distrust towards media, politics and established institutions around the world. And while new technologies like artificial intelligence (AI) might make things even worse, it can also be used to combat misinformation.
The upcoming European elections will reveal how recent challenges such as immigration, the financial crisis, Brexit and the rise of populist parties will play out in the political arena. But the elections are also providing an opportunity for researchers to understand how to better engage voters and ensure the European Union remains relevant to its citizens.
Europe’s minority languages have been squeezed by nation-building, urbanisation and the ‘lingua francas’ of the internet, according to Professor Anneli Sarhimaa, specialist in Northern European and Baltic languages and cultures at the University of Mainz, Germany. But one lesson she has learned from researching the fate of the Finnic language Karelian, spoken in Finland and north-western Russia, is that digital media can also help revitalise them.
Metagenomics can help us spot emerging diseases, says virologist Marion Koopmans.
What are they and why are they promising for coronavirus?
The more satellite launches we do, the bigger the risk of damage or debris, says Dimitra Stefoudi.
