CERN announces a charming new particle

The observation of a new particle containing two charm quarks and one up quark has been reported by the LHCb experiment at CERN’s Large Hadron Collider. The existence of this particle from the baryon family was expected by current theories,

Happy 5th anniversary, Higgs boson!

Where were you on 4 July 2012, the day in which the Higgs boson discovery was announced? Many people will be able to answer without referring to their diary. Perhaps you were among the few who had managed to secure

Hints of extra dimensions in gravitational waves?

Researchers  found that hidden dimensions – as predicted by string theory – could influence gravitational waves. In a recently published paper they study the consequences of extra dimensions on these ripples in space-time, and predict whether their effects could be

A single electron triggers ‘Molecular Sunscreen’

In experiments scientists were able to see the first step of a process that protects a DNA building block called thymine from sun damage: When it’s hit with ultraviolet light, a single electron jumps into a slightly higher orbit around

A 100-year-old physics problem has been solved

At EPFL, researchers challenge a fundamental law and discover that more electromagnetic energy can be stored in wave-guiding systems than previously thought. The discovery has implications in telecommunications. Working around the fundamental law, they conceived resonant and wave-guiding systems capable

Cosmic inflation: Higgs says goodbye to ‘little brother’

In the first moments after the Big Bang, the Universe was able to expand even billions of billions of billions of times faster than today. Such rapid expansion should be due to a primordial force field, acting with a new

New confirmation of Einstein’s theory of relativity

Albert Einstein predicted that whenever light from a distant star passes by a closer object, gravity acts as a kind of magnifying lens, brightening and bending the distant starlight. Yet, in a 1936 article in the journal Science, he added

Quantum physicists build on Einstein and Galileo’s work

Sixteenth century scientist Galileo Galilei threw two spheres of different mass from the top of the Leaning Tower of Pisa to establish a scientific principle. Now nearly four centuries later, a team of Italian physicists has applied the same principle to

Merging black holes release more energy than entire universe

The Laser Interferometer Gravitational-wave Observatory (LIGO) has made a third detection of gravitational waves, ripples in space and time, from merging black holes, demonstrating that a new window in astronomy has been firmly opened. As was the case with the

Breaking glass in infinite dimensions

Thirty pages of calculations settle a 30-year debate over a mysterious new phase of matter. Zoom in on a crystal and you will find an ordered array of atoms, evenly spaced like the windows on the Empire State Building. But zoom
