We Now Know What Caused The Weird Eruptions On Rosetta's Comet

Last winter, something strange happened on Rosetta’s comet. After a period of calm, the comet began erupting, throwing huge jets of comet dust into space before abruptly stopping. Now, we finally know what happened.


The Five-Second Rule Still Doesn't Work

Actual lab tests have revealed that the commonly-cited five-second rule doesn’t hold up. And yet, they still can’t stop me from eating this piece of floor candy! Who’s in charge now, Science?


Two 'Unprecedented' Hurricanes Are Churning Toward Hawaii

In what’s being hailed a meteorological first, two back-to-back hurricanes are marching toward Hawaii, both of them threatening torrential rains and rip-roaring winds this week. The closer of the two, hurricane Madeline, could break a second meteorological record as the first hurricane to strike the Big Island since bookkeeping began in 1949.


In 1898, Nikola Tesla Predicted Drone Warfare

Nikola Tesla was both of his time and ahead of it (he has a car company named after him, after all). Besides his contributions to alternating current electrical systems, the inventor predicted smartphones, television and apparently drones, which he thought could cause humanity’s destruction.


The Terrifying Reason This Star Flickers Every Two Minutes

Some 380 light years away in the constellation Scorpius lies a star that has puzzled astronomers for over 40 years. Called AR Scorpii, the star flashes brightly and fades again every couple minutes, like a lightbulb on a dimmer switch. Now, astronomers have identified the cause of the flickering, and it’s a reminder that the cosmos is still rife with terrifying secrets.


5 Amazing Facts About NASA's Mission To Jupiter

After five years and 716 million kilometres, NASA’s Juno mission arrives in orbit around Jupiter this week to begin an unprecedented scientific study of the behemoth planet that shaped our solar system.


This 'Hourglass' Liquid Battery Runs On Gravity

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.


A Camera Lens Breakthrough Could See Smartphones Outperforming DSLRs

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.


Experts Held Secret Meeting On Building A Human Genome

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.


A Major Mystery About Earth's Magnetic Field Has Just Been Solved

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.
