Watch Water Get Tied In A Knot

How do you tie water in a knot? First you make parts of it into vortices, which move more like long continuous strings than groups of autonomous molecules. Then you need to tangle those strings together.

Here's How Black Holes Turn On The Lights In The Universe Around Them

Despite their popular reputation as dark inescapable pits, black holes really put out a lot of energy. They thrust out jets of matter. They get matter to heat up through friction as it swirls around them. And, in some cases, they contribute to bursts of incredibly high energy photons, thanks to a phenomenon first encountered in the 1920s here on Earth.

Neutrinos Change Their Flavour And Snag Another Nobel Prize

Early this morning the world learned that the 2015 Nobel Prize in Physics has been awarded to Takaaki Kajita and Arthur B. McDonald for discovering that neutrinos can change from one type to another, evidence that — contrary to prior scientific consensus — they must have mass.

How A Giant Lift Harnesses Gravity To Move Boats

You’re probably aware that normal elevators make use of counterweights, which reduce the amount of energy it takes to move people up and down skyscrapers with slightly frightening speed. But when it comes to moving hundred-ton boats, a little more precision is required.

After The Supermoon, Came The Supertide

Many locations along the UK, US and Australian coasts will experience their highest tides for tens of years around September 29 or 30. Coastal roads in Miami, for instance, have already been closed in anticipation of exceptional tides.

That T-Junction In Your Sewer Line Is A Trap 

Your sewers have T-junctions — places were two pipes come together and form a “T” shape. So do your arteries. A new study has found that these junctions can trap tiny particles of matter, blocking normal healthy flow.

We're One Small Step Closer To A Working Light Saber

Killjoy physicists have long pointed out the sheer unlikelihood of building a working light saber. But now, they have taken a small step toward realising the dream of Star Wars fans worldwide, by figuring out how to get photons to stick together like molecules in a super-chilled gas.

Master The Art Of Sabrage With This Space-Age Champagne Saber

This sleek, space-age stainless steel take on a saber from Menu is proof that a champagne saber doesn’t need to be sharp to get the job done. It’s the impact that matters, after all, not the sharpness of the blade.

One Physicist's Quest For New Physics Beyond Einstein And The LHC

All eyes are currently on the upgraded Large Hadron Collider as it ramps up its hunt for new physics. But some physicists are already looking beyond and pinning their hopes on an even bigger machine, four times the size of the LHC. One of them is Nima Arkani-Hamed, the subject of a recent extensive profile by Natalie Wolchover at Quanta.

This 15-Tonne Magnet Is Now Ready To Study Mysterious Particles

Last year, a massive, 15.4-tonne, 15.85m wide electromagnet was successfully shipped from Long Island to Illinois. This week, it hit another milestone: It was successfully chilled to absolute zero temps after 10 years’ inactivity, proving it’s ready to solve a whole new decade’s physics mysteries.
