Israeli airstrikes on oil facilities in Tehran on 7 March led to sulphur dioxide emissions equivalent to a small volcanic eruption, potentially exposing people as far away as China to acid rain and toxic air pollution. As part of the US and Israeli campaign against Iran, warplanes struck several oil depots and a refinery that night, sparking massive fires that lit up the sky and spewed smoke for days. Black rain containing soot and hydrocarbons fell on the Iranian capital, and residents reported eye and skin irritation and difficulty breathing. Now, satellite data has shown that the plume of sulphur dioxide released by these explosions and fires covered 300,000 square kilometres, passing over several countries. Read more

Wherever you are reading this, look around you. Every living thing you can see – other people, pets, trees, flowers, mushrooms – is here because of unions between different species. This symbiosis, which means “living together”, has been neglected in our explanation of biology and ecology thanks to an emphasis on the role of competition in the evolution of life, argues Rowan Hooper. But if we stop focusing on the individual and instead look at life through the lens of togetherness, we get a whole new picture of how life on Earth – and elsewhere – may have begun. Read more
