Can You Help CERN Identify What's Happening In These Archive Images?

As an institute full of scientists, you might think CERN was good at keeping records. But it’s happened upon a stash of archived images that seem to make no sense whatsoever — and it wants you to help it work out what they show.


This Is What Happens In Slow-Mo When You Shoot Liquid Drops With Lasers

Lasers? Fun. Slow motion? Beautiful. Shooting things with lasers and recording what happens in slow motion? That will be what happens in this beautiful video.


Monster Machines: Scientists Are Creating The Coldest Cubic Metre In The Universe

It’s hard to describe exactly how cold the coldest cubic metre in the universe will be. Frozen to just a blip above absolute zero — the temperature at which atoms cannot even vibrate — the CUORE experiment will try to nail down a tiny number that has long eluded physicists: the mass of a neutrino.


How To Measure Distance In Space

Space is expansive. Looking up to the stars, it can sometimes feel like everything sits on a single, two-dimensional sheet held up above us. It doesn’t, of course — so how do we measure how far away things are?


A Brief History Of Scientists Hunting For Time Travellers

Time travel is possible — or at least a lot of serious physicists say so. It’s probably not possible to pull it off in a souped-up Delorean, but there are wormholes, Tipler cylinders, and other Einstein-inspired theories for how it could work. Which raises the question: Why haven’t we met any visitors from another time?


Inventors Of The Blue LED Inside Nearly Every Device You Own Win Nobel Prize

There’s pretty good chance you have a piece of this year’s physics Nobel prize-winning invention in your pocket. The blue light-emitting diode (LED) is found in the screens of millions of phones as well as our bright, new energy-efficient LED lightbulbs. Today, the Nobel Prize in physics was awarded to the three scientists who made this revolutionary discovery.


This Particle Is Matter And Antimatter At The Same Time

You might think that matter and antimatter aren’t the best of friends, cancelling each other out when they come into contact — but you’d be wrong. In fact, researchers have now discovered a particle that’s made up of both.


Giz Explains: Why The Human Body Can't Handle Heavy Acceleration

Our bodies are surprisingly resilient in many situations, but rapid acceleration is not one of them. While the human body can withstand any constant speed — be it 20km/h or 20 billion kilometres per hour — we can only change that rate of travel relatively slowly. Speed up or slow down too quickly and it’s lights out for you, permanently.


Scientists Make The World's Smallest 'Microphone' From A Single Molecule

With a name like “microphone”, you’d expect something small — but perhaps not quite as small as this. Scientist have figured out how to use just one molecule to detect the vibrations from sound.


Moon Seismometers From Apollo Are Still Helping Solve Physics Mysteries

When Apollo astronauts landed on the moon, they left flags and footprints, yes, but also dozens of scientific instruments. Among them was a network of seismometers originally meant to study moonquakes. Forty years later, data from these seismometers are still helping physicists understand how to detect elusive gravitational waves — a challenge even with our fancy modern technology.
