“You can see the patient’s internal structures mapped onto their body”Robot surgeons, page 22 Wherever there’s a marriage of amazing technologies, the result is often greater than the sum of its parts. You might only ever encounter virtual and augmented reality features in your smartphone or on a games console, but it’s set to be the standard for surgeries of the future. Step into a surgeon’s shoes on page 22 and find out how robots, VR and AR are revolutionising hospitals. On page 70, we delve into a pet subject of my own: how prehistoric animals, long-extinct, have been so immaculately preserved in Siberian ice, peat bogs and sticky tar pits around the world.

jupiter marble

On 12 February this year, NASA’s Juno spacecraft made a close pass of the largest planet in the Solar System. The craft’s JunoCam, a mounted visible-light camera that takes photos in strips as the spacecraft spins, took a series of snaps over the course of an hour, between 26,900 and 95,400 kilometres above the tops of Jupiter’s clouds. This image of the Great Red Spot and Jupiter’s southern hemisphere, dubbed ‘Jupiter Marble’, was put together using three of JunoCam’s images by citizen scientist Kevin M. Gill.…

tiny living pest control

This is a rust mite (Aceria anthocoptes) on a plant sample, magnified 1,400 times under an electron microscope. This little living bug is around 60 micrometres long, too small even for the sharpest human eyes to detect. Rust mites were only discovered just over 100 years ago but have since been observed feeding on the invasive plant species Canada Thistle (Cirsium arvense), and have been recognised as a natural pest control method. This plant is native to Europe but is considered a weed when it spreads on other continents.…

is earth a ‘galactic zoo’?

Why hasn’t Earth received any messages from extraterrestrials yet? One possibility is because we’re unwitting inhabitants in a so-called 'galactic zoo'. This was one of the scenarios a group of international researchers explored at a meeting organised by the non-profit organisation Messaging Extraterrestrial Intelligence (METI) last month. The gathering, which took place at the Cité des Sciences et de l'Industrie museum in Paris, brought together around 60 scientists who've researched the possibility of communication with hypothetical intelligent extraterrestrials. They debated 'The Great Silence' – why aliens haven’t contacted us – exploring one possibility known as the 'zoo hypothesis'. First proposed in the 1970s, it describes Earth as a planet that is already under observation by 'galactic zookeepers' who are deliberately concealing themselves from human detection and have agreed to treat Earth…
