The atomic clocks that keep satellites and your smartphone on time
The US Naval Observatory is home to a set of incredibly precise atomic clocks that record America's official time. Its clocks are relied upon for a vast range of functions, from providing the time on your smartphone lock screen to keeping GPS satellites accurate in their calculations. The clocks, and the service they provide, are presided over by Dr. Demetrios Matsakis, chief scientist for the observatory's time services department.

New State of Matter Discovered
There was a time when states of matter were simple: Solid, liquid, gas. Then came plasma, Bose -Einstein condensate, supercritical fluid and more. Now the list has grown by one more, with the unexpected discovery of a new state dubbed “dropletons” that bear some resemblance to liquids but occur under very different circumstances...

New type of ‘ultracold’ molecule ideal for quantum computing
Researchers have created a new type of “ultracold” molecule, using lasers to cool atoms to about one thousandth of degree above absolute zero using lasers and then gluing them together, a technology that might be applied to quantum computing, precise sensors, and advanced simulations.

Anti-Gravity Wheel?
In this video I attempt to lift a 19kg (42 lbs) wheel over my head one-handed while it's spinning at a few thousand RPM. This replicates an earlier experiment by Professor Eric Laithwaite. He claimed the wheel was 'light as a feather' and could not be explained by Newton's Laws. I wanted to find out for myself what I really felt like.

NIST Launches a New U.S. Time Standard: NIST-F2 Atomic Clock
NIST-F2 would neither gain nor lose one second in about 300 million years, making it about three times as accurate as NIST-F1, which has served as the standard since 1999. Both clocks use a "fountain" of cesium atoms to determine the exact length of a second.

Physics-exploiting axe splits wood in record time
Chopping wood is hard, but it’s something modern society has largely freed us from as a daily activity. That’s nice, but consequently, if you ever do have to chop wood, you’re more than likely going to suck at it. Splitting a log requires a surprising amount of force, but Finnish inventor Heikki Kärnä has invented a new kind of axe that makes it much easier and safer.

Scientists ‘freeze’ light for an entire minute
In what could prove to be a major breakthrough in quantum memory storage and information processing, German researchers have frozen the fastest thing in the universe: light. And they did so for a record-breaking one minute.

Can You Slow Down a Day Using Angular Momentum?
Could a spinning human slow down the Earth? Theoretically, yes. But in practice, the amount of spin you'd have to give would be so monstrous that it is nearly impossible.

Why Does the Balloon Move Forward in an Accelerating Car?
So, the car is accelerating forward and the balloon also leans forward. Why? Well, Destin gives a very nice explanation focusing on the air in the van. The air in the car has a higher density in the back of the vehicle than it does in the front. This means that the net force on the balloon due to collisions with the air will be in the forward direction.

Scientists Create Element 117, Which Is 40% Heavier Than Lead
Element 117, a super-heavy atom with a long half-life is, according to an international team of scientists, real and ready to take its place on the Periodic Table. Scientists actually confirmed the existence and lifetime of the element in 2010 thanks to experiments conducted by teams in Russia and the U.S. However, now researchers in Germany and the U.S. have created the actual element, which is reportedly 40% heavier than an atom of lead, according to a report in Phys.org.

Big Bang Discovery Comes Under Fire
Concerns rise over a rumored error in observations of gravitational waves rippling through the aftermath of the big bang. In March the Background Imaging of Cosmic Extragalactic Polarization 2 (BICEP2) team headed by Harvard's John Kovac announced a pioneering observation of cosmological "gravitational waves" first predicted by Einstein to headlines worldwide. The claim seemed to confirm the conventional cosmological view of the universe expanding exponentially in its earliest instant.

How to Turn a Star Into a Supermagnet
Astronomers have figured out how to make the universe’s most powerful magnet. All you need is two massive stars orbiting close to each other so that one swipes gas from the other, causing the thief to spin so quickly that its magnetic field dwarfs that of Earth by 100 trillion-fold. The finding offers fresh insight into how some of the galaxy's smallest but most extraordinary stars arise.

Supermassive Black Hole At The Centre Of The Galaxy May Be A Wormhole In Disguise, Say Astronomers
One of the most extraordinary objects in the Milky Way galaxy is Sagittarius A* (pronounced Sagittarius A star). This small object is a bright source of radio waves in the constellation of Sagittarius that was discovered in 1974. Since then, astronomers have made numerous observations of Sagittarius A* and the stars nearby, some of which orbit it at very high velocity. That implies that Sagittarius A* is extremely massive and since it is so small it must also be hugely dense.
