The Baryon Antibaryon Symmetry Experiment (BASE) at CERN’s Antimatter Factory has set new limits on the existence of axion-like particles, and how easily those in a narrow mass range around 2.97 neV could turn into photons, the particles of light. BASE’s new result, published by Physical Review Letters, describes this pioneering method and opens up new experimental possibilities in the search for cold dark matter.
Axions, or axion-like particles, are candidates for cold dark matter. From astrophysical observations, we believe that around 27% of the matter-energy content of the universe is made up of dark matter. These unknown particles feel the force of gravity, but they barely respond to the other fundamental forces, if they experience them at all. The best accepted theory of fundamental forces and particles, called the Standard Mod

Nicole first soared to fame on TOWIE when she appeared for two seasons in 2015 as the ex-girlfriend of Lewis Bloor, before departing the programme however she has since returned and is a current cast member.
In 2017 - following her first TOWIE departure - she wowed fans by hitting MTV s Ex On The Beach where she was at the centre of the drama.
Oh my! The TOWIE and Ex On The Beach star, 28, slipped into the revealing two-piece while posing up a storm in the sizzling swimwear which flaunted all her best bits
Stunning: Nicole looked incredible as she posed up a storm in the sexy bikini, which featured a delicate pattern and some dazzling adornments
Tim Roth’s renegade cop in Tin Star is one believable bloke
4/5
In a review of the opener of the final series, it s Roth that keeps you hooked - and boy, would you not want to meet him down the pub
Tim Roth returned as sheriff Jim Worth for the final series of bloodthirsty drama Tin Star
Somewhere nestled comfortably in the Canadian Rockies was the quaint little oil town of Little Big Bear. And somewhere nestled uncomfortably between Twin Peaks, Fargo and the oeuvre of Quentin Tarantino, was the crime drama Tin Star, complete with its quaint little British sheriff, Jim Worth (Tim Roth). Little Big Bear’s oil company, however, was corrupt and Jim, it turned out, wasn’t Jim, but Jack Devlin, a psychotic, hard-drinking former undercover cop, whose true self burst bloodily to the fore when his cute poppet of a son was killed.
