Scientists at MIT have designed an ingenious new concept for a battery that operates on the same fundamental principal as an hourglass — it relies on gravity to generate energy. They described the device in a recent paper for Energy and Environmental Science.

If you've ever held a high-quality camera lens, the first thing you notice is the weight. Thanks to layers and layers of thick glass hunks inside, they end up being very heavy. However, thanks to research being done at Harvard on something called metalenses, one day those giant glass-filled lenses might be obsolete.
Earlier this week, over a hundred scientists, lawyers and entrepreneurs gathered to discuss the radical possibility of creating a synthetic human genome. Strangely, journalists were not invited and attendees were told to keep a tight lip. Which, given the weighty subject matter, is obvious cause for concern.
For the first time, physicists have observed a mysterious process called magnetic reconnection — wherein opposing magnetic field lines join up, releasing a tremendous burst of energy. The discovery, published in Science, may help us unlock the secrets of space weather and learn about some of the weirdest, most magnetic objects in the universe.
When Canadian Prime Minister Justin Trudeau schooled a journalist on the basics of quantum computing yesterday, I was initially as charmed and delighted as everyone else. But then a niggling sense of dismay set in. Why should this be such a singular newsworthy event? How come so few of us can do what Trudeau did, when science plays such a central role in almost every aspect of our daily lives?
Every week people all around the world spend 3 billion hours playing games. Games are entering almost all areas of our daily life and have the potential to become an invaluable resource for science.
Citizen science games have already proved successful in advancing scientific endeavours such as protein folding and neuron mapping. However, this approach had not previously been applied to quantum physics, and a recent study has now shown that gamers are solving a class of problems in quantum physics that cannot be easily solved by algorithms alone.
I'm sure our inevitable robot overlords will dish out sufficient payback 50 years from now, but today, it's better to send in machines than humans when the work required is sufficiently dangerous. When it comes to maintaining the Sydney Harbour Bridge, NSW's Roads and Maritime Services agrees and as such, have enlisted mechanical aid for the job, courtesy of the University of Technology Sydney.
A sonar reading recently revealed a previously unseen trench at the bottom of Loch Ness. Located about 14.5km east of Inverness, it looks just large enough for Nessie to hide in. Or more plausibly, it's yet another attempt by the locals to keep the myth alive — and the tourists flocking to the lake.
In our 24/7 culture, sleep loss is a major problem. Back in 1942, we averaged almost 8 hours of sleep a night — now that’s down to 6.8. (Seven to 9 hours per night are what’s generally recommended.) Almost 40 per cent of Americans get less than seven hours of sleep a night, a recent Gallup poll found, and an estimated 70 million Americans have a sleep disorder. Everyone knows that it’s important to get enough sleep — but you may not realise just how many things can go wrong when you don’t.
Episode 6: best and worst! The games, gadgets, movies and science stories that most caught our attention in 2015. We also chat with renowned theoretical physicist and string theorist, professor Brian Greene.
Personally, I need breakfast. Almost every morning, I wake up early feeling hungry, and it’s only once I banish my morning hunger that I’m ready to fire. By mid-morning, I take a break and enjoy a snack.
I’ve used a personal anecdote because it’s likely that eating breakfast – or skipping it – may simply reflect a personal preference for timing food intake. Not everyone enjoys eating first thing in the morning. But your first choice of foods may contribute to an overall healthy diet.
If the notion that humans will one day ascend into orbit on a rope of ultra strong carbon nanofibres sounds a bit out of this world, then you're going to love the latest dazzling twist: our future space elevators might actually be built of diamond.
Yesterday the Royal Swedish Academy of Sciences awarded the Nobel Prize in Chemistry to Tomas Lindahl, Aziz Sancar, and Paul Modrich for their work in mapping out how cells repair damaged DNA. Their research improved our understanding of how our own cells work and helped in the development of cancer treatments, but what does it all really mean?
