How Bigger Atoms Could Help Make Smaller 'Lab-On-A-Chip' Devices

“Lab-on-a-chip” devices — which can carry out several laboratory functions on a single, micro-sized chip — are the result of a quiet scientific revolution over the past few years. For example, they enable doctors to make complex diagnoses instantly from a single drop of blood.


Can Lightning Strike An Indoor Pool?

Two swimming pool weather policies have surprised me in recent years. One was when I showed up to swim laps at an outdoor pool as it was beginning to drizzle. “Come on in,” I was told; as long as there was no lightning, the pool was still open. So I had one of my weirdest swims ever: you turn your head out of the water to breathe, but your face is still wet. Thanks, rain.


We May Have Dramatically Misunderstood The Shapes Of Black Holes

Even if you didn’t see Interstellar, you’ve probably heard about how black holes have an “event horizon” — and, once you pass it, you’re mashed into multi-dimensional mush. But now some physicists believe we got it all wrong. Black holes are more like fuzzy balls of cotton with no event horizons at all.


A Sheet Of Graphene Is The World's Thinnest Lightbulb

Amid a revolution in low-energy lighting, some scientists are returning to older ways of thinking. Now, graphene has been turned into a working filament, lighting up when it’s pumped with electricity.


Watching Water Filled Condoms Explode Is Suprisingly Mesmerising

Ever wonder what happens when you fill a condom with water, spin it up with a drill, and jab it with a knife? Maybe not, but now you’re thinking about it. Thankfully, the Slo Mo Guys have yet another mesmerising demonstration to feed our imaginations.


Every Satellite Got Into Space Thanks To Newton's Law Of Gravitation

What goes up must come down — though not always in the way you’d expect. This is Newton’s Universal Law of Gravitation, and you can thank it for GPS, Google Earth and even the pictures beamed back from the other side of the Solar System. Here’s why.


New Solar Storm Forecast Gives Over 24 Hours Warning Of Disruption

Solar storms start their lives as violent explosions from the sun’s surface. They’re made up of energetic charged particles wrapped in a complex magnetic cloud. As they erupt from the sun’s surface, they can shoot out into interplanetary space at speeds of up to 3000km per second. Depending on their direction of travel, these energetic storms can journey past Earth and other planets.


A Stealth Energy Startup Just Made A 10x Improvement To Its Fusion Tech

Tri Alpha Energy does not have a website. Its office in California is unmarked. But this stealth company apparently has hundreds of millions in cash. And now it has something to show for it, reports Science: The company claims it’s gotten ten times better at containing high-energy particles necessary for fusion energy.


The Physics Behind Ice Spikes, Nature's Perfect Murder Weapon

Ice spikes may very well be the perfect untraceable weapon, but how do these jagged sticks of frosty death form? Turns out there’s no magic involved (womp), just some simple physics.


The Seashell-Inspired Material Creating A New Wave Of Safety Gear

The risk of injury in professional sport has been a central feature in recent debates about how well protected our stars are. Only recently, Argentine football player Emanuel Ortega died of a fatal head injury after hitting a concrete wall during a game.
