There are about 1,500 potentially active volcanoes worldwide and about 50 eruptions occur each year. But it’s still difficult to predict when and how these eruptions will happen or how they’ll unfold. Now, new insight into the physical processes inside volcanoes are giving scientists a better understanding of their behaviour, which could help protect the 1 billion people who live close to volcanoes.

Artificial intelligence (AI) used by governments and the corporate sector to detect and extinguish online extreme speech often misses important cultural nuance, but bringing in independent factcheckers as intermediaries could help step up the fight against online vitriol, according to Sahana Udupa, professor of media anthropology at Ludwig Maximilian University of Munich, Germany.

Dr Luciano Zuccarello grew up in the shadow of Mount Etna, an active volcano on the Italian island of Sicily. Farms and orchards ring the lower slopes of the volcano, where the fertile soil is ideal for agriculture. But the volcano looms large in the life of locals because it is also one of the most active volcanoes in the world.

Online voting is often considered a way to improve voter turnout and security. But according to Dr Steve Kremer of the French Institute for Research in Computer Science and Automation, computer scientists have got a long way to go before they make it a viable alternative to pencils and paper.

Robust, intelligent robots that react to their surroundings are being developed to work in situations that are too dangerous for humans, such as cleaning up Europe’s decades-old radioactive waste or helping during a nuclear emergency.

From high winds and heavy rainfall to droughts and plummeting temperatures, people in Europe have already begun to feel the effects of extreme weather. As we get used to this new reality, scientists are investigating how it will affect how we get around and whether our infrastructure can cope.

Airports could be equipped with technology capable of detecting and bringing down drones that stray into their air space, according to Dan Hermansen, chief technology officer of Danish anti-drone firm MyDefence. The company has developed a drone alarm and protection system that is being installed at a number of prominent sites around Europe, including an airport. It has the potential to prevent the kind of costly disruption that hit London’s Gatwick and Heathrow airports recently.

The eruption of a volcano can have devastating consequences – killing people and destroying livelihoods, as well as releasing vast amounts of ash into the sky that disrupts air travel and alters the climate. Knowing what goes on underground, however, would facilitate better warnings for when an eruption will occur – and help save lives while keeping damage to a minimum.
