We definitely dig this. NASA has started testing the Regolith Advanced Surface Systems Operations Robot (RASSOR). This robot is designed to mine resources on the surface of asteroids, the Moon or even Mars. The bot is in development at Kennedy Space Center in Florida. The agency has released a video showing a simulated mission in …
Japanese researchers have successfully raised mice, using stem cells that they transformed into egg cells. Though the technique has so far only been proven using mice, it could one day help infertile human couples to have children without the need for egg donors, researchers say. The team, led by Katsuhiko Hayashi at Kyushu University, took …
1. Minimise Swaying To avoid swaying, choose a seat close to the centre of gravity of the bus, midway between the front and back wheels. As the bus turns a corner, this point will travel in a smooth circle. That’s better than the front or back, where you travel in a narrow ellipse that lurches …

It seems abnormalities in grey matter may lead to black moods. A team based at Warwick University and China’s Fudan University has found evidence that depression has a physical root in the brain. The findings could lead to new treatments for depression by targeting the root cause of the illness and helping depressed people to …
Flying over the Philippine Sea, an astronaut looked toward the horizon from the International Space Station and shot this photograph of threedimensional clouds, the thin blue envelope of the atmosphere, and the blackness of space. The late afternoon sunlight brightens a broad swath of the sea surface on the right side of the image. In …
Ever since the grand unveiling in 1905, the colossal skeleton of Dippy the Diplodocus has been one of the stars of the Natural History Museum, and she’s welcomed visitors to the Hintze Hall since the 1970s. So there was something of a commotion when the museum announced last year that Dippy was due to be …
The hearing range of nearly all mammals is wider than the frequency range they can produce with their voices. This is because the top end of our hearing range has evolved to help us accurately detect the direction of a sound. The ear facing away from the sound hears less of the higher frequencies because …

If the Sun miraculously disappeared, the Earth (and all the other objects in the Solar System) would continue their forward motion in a straight line off into space, instead of following their almost-circular orbits. For the Earth this means it would head off towards the stars at about 30km/s (67,000mph). There may be some subsequent …

Far from it: many substances can be found in more than three states of matter, while others have fewer than three. All the chemical elements can be induced to form solids, liquids or gases. But if you superheat a gas, then the electrons get stripped away from the nuclei to form plasma. Stars are made …
The polygraph test, still used widely in the US, measures your heart rate, breathing and blood pressure as a way to tell how stressed you are feeling. The idea is that the interrogator asks you questions and when you lie, you get more stressed than when you tell the truth, and this difference is revealed …
In 2011 a team of physicists in Spain created a perfectly smooth material by coating a thin silicon crystal with a layer of lead a dozen or so atoms thick. According to the team, quantum forces between the atoms levelled out even atom-sized bumps. The result was a surface known as a quantum-stabilised atom mirror, which will be used …
The internet is made from a vast global collection of computer networks that all interconnect. In contrast, the Internet of Things (also known as ‘ubiquitous computing’) is a set of smart devices that connect to the internet, making them accessible remotely. Today we have connected heating thermostats, security cameras, motion sensors, lights, doorbells and even …
The first punch might, because the assailant can’t brace against the ground, so some of the momentum of his fist will be wasted pushing his body backwards. But once the two brawlers are pushed in opposite directions to the walls of their spacecraft, they will be able to launch themselves back again. The second punch will be boosted by the forward momentum of …
