During World War II, a German officer is reputed to have said that the US military did so well in war “because war is chaos, and the American army practises chaos on a daily basis”. Today, its activities are plunging Earth into chaos on an entirely different scale: the US military emits more carbon dioxide than most countries, and in a table of nations, its carbon “bootprint” would sit above Portugal’s. Through its tanks, jet planes and aircraft carriers – not to mention its supply chains of trucks, cargo planes and container ships – the US military is the largest institutional consumer of hydrocarbon fuels in the world.
Finding all this out wasn’t easy – the US has consistently tried to excuse its military from carbon emission assessments. As presidential candidates debate climate action, the researchers argue that shrinking history’s largest war machine should become a campaign priority, and action should be about more than humvees running on biofuels or solar powered drones.
From Viagra to slimming pills, it can sometimes be rather embarrassing to ask a doctor or pharmacist for drugs. It’s no wonder, then, that we are increasingly buying pharmaceuticals online. But, while convenient, this development has boosted the market for unregulated websites that sell fake medicines – illegal and substandard pharmaceuticals that largely used to be a problem in low and middle-income countries.
Providing basic healthcare in a country where power outages can last months is not easy, but a dentist in Sudan has found a way to save children’s rotting teeth, despite the difficult circumstances. He simply glues a cap on the offending tooth – no drilling, no anaesthetic. The lack of oxygen kills the bacteria and saves the tooth. It’s cheap, it’s quick and his latest study shows that it works.

Jumping spiders, like this one, usually have eight eyes: two very large front eyes to get a clear, colour image and judge distance, and extra side eyes to detect when something is moving.

Human eyes are very complex and are good at doing many jobs at once, while spiders have different sorts of eyes that do different jobs.
