Editor's note

In one of the worst epidemics the UK has ever seen, ash dieback threatens to kill 95% of Britain’s 150m native ash trees and is estimated to cost the economy £15 billion. The disease – caused by a fungus and introduced to the country through imported saplings – has been met with little resistance by the trees. While the trees may be unable to defend themselves, Nick Atkinson, who came up with the figures, says people aren’t powerless to prevent this kind of damage.

Research of nearly 200 teenagers has found that many don’t see online abuse as a problem – even posts that are illegal. From revenge porn to hate speech, many of these teenagers considered abusive posts “normal” and thought it unlikely that anyone would get in trouble with the police. In that regard, writes Holly Powell-Jones, they might be right.

Some of the most deadly diseases in the world pass between humans and other animals. When epidemics strike, frantic vaccination efforts are often human-focused, leaving thousands of animals dead. Ebola, for example, has wiped out a third of the world’s chimps and gorillas. But what if we could develop vaccines that worked across species? In a world first, George Warimwe is doing exactly that to tackle Rift Valley Fever, a devastating disease that affects millions of humans and livestock. He explains how this new approach could save time, money, and lives – of all species.
