‘We still don’t know enough about the dangers of microplastics’

There is 'large uncertainty' surrounding the risk from microplastics, pieces of plastic less than 5mm wide, says Prof. Bart Koelmans.

by Jonathan O’Callaghan An estimated 5.25 trillion particles of plastic float in Earth’s oceans, threatening not only the health of marine ecosystems and animals, but that of humans in the water we drink and the food we eat. However, research into the extent of the dangers posed by microplastics is still just in its infancy. … Read more

In a picture: ‘Now we know what a black hole looks like’

by Jonathan O’Callaghan The first-ever image of an event horizon – the gravitational boundary of a black hole beyond which light cannot escape – was revealed on 10 April and is the best evidence yet that these phenomena really do exist. It was the result of a global collaboration of hundreds of scientists, using multiple … Read more

Gravitational waves – the invisible ripples in the fabric of space predicted by Albert Einstein – are opening up a new era of astronomy that is allowing scientists to see parts of the universe once thought to be invisible, such as black holes, dark matter and theoretical subatomic particles called axions. Almost 100 years after … Read more

‘Trusting self-driving cars is going to be a big step for people’

When self-driving cars start to operate in a real-life context, it could be transformative for people's perception of autonomous driving, says Dr Bonnefon.

Self-driving cars are set to bring one of the biggest changes to our global transportation system in decades, but their potential to increase road safety should not be over-emphasised if we want to increase people’s trust in automated vehicles, says Dr Jean-François Bonnefon from the Toulouse School of Economics, France, and Massachusetts Institute of Technology, … Read more
