Spotted: thousands of wild tigers! Big news! An international organisation that works to save animals has announced that there are as many as 5,578 wild tigers in the world, 40 per cent more than we thought there were. This is great news for tigers. But it might be an even bigger win for the people who count them. It turns out that at least some of that 40 per cent increase isn't because the tiger population is growing. It's because humans are getting better at finding them.

Readers ask. Experts answer. Send your questions to: experts@britannicamagazine.com DR NATHAN SMITH Palaeontologist Question: When were the first dinosaurs alive? From Robert, age 8 Answer Dinosaurs first emerged in the Late Triassic period, which began 237 million years ago. Fossils of the earliest dinosaurs to be discovered so far were found in the Ischigualasto Formation in northwestern Argentina in South America. Some of these fossils have been dated to around 230 million years ago. Dinosaur fossils are relatively rare at this palaeontological site, but around half a dozen dinosaur species have been described and named. They include prehistoric animals such as Herrerasaurus (see the artist's illustration, above) and Eoraptor. We know of lots of animals closely related to dinosaurs that were alive earlier in the Triassic period, so it is…

What is the best way to launch a satellite into space? For the last 70 years, the answer has been the same: load the satellite onto a rocket and then blast the rocket up into space. However, space rockets need to burn a lot of expensive and environmentally unfriendly fuel to generate enough power to break free from Earth's gravity. To solve this problem, a new machine called the SpinLaunch is trying a different approach. It spins the rocket around at speeds of up to 5,000 mph, before releasing the rocket so it's sent flying 30 miles up into the atmosphere. A half-size version of the SpinLaunch is already being tested in New Mexico, USA. If it is successful, a full-size SpinLaunch is planning to hurl its first satellites into…
