Scientists in Germany say they have hit a new superconductivity milestone. According to their paper, they achieved resistance-free electrical current at the highest temperature yet: just 250 Kelvin, or -23 degrees Celsius (-9.4 degrees Fahrenheit). Although the team’s superconducting material has yet to be verified, the claim has merit – the work was led by

Atomic clocks, based on the minute oscillations of atoms, are the most precise timekeeping devices humans have created. Every year, scientists make adjustments that improve the precision of these devices. Now, they’ve achieved new performance records, making two atomic clocks so precise they could detect gravitational waves, those faint ripples in the fabric of space-time.

Humanity just made a weighty decision. On Friday, representatives of more than 60 nations, gathered in Versailles, France, approved a new definition for the kilogram. Since the 19th century, scientists have based their definition of the fundamental unit of mass on a physical object — a shining platinum iridium cylinder stored in a locked vault

Strap yourselves in, because CERN has something up its sleeve. On Thursday 1 November, Large Hadron Collider (LHC) physicists will be discussing the fact that they may have found a new and unexpected new particle. “I’d say theorists are excited and experimentalists are very sceptical,” CERN physicist Alexandre Nikitenko told The Guardian. “As a physicist

More than eight decades after they were predicted to exist, physicists have found evidence of discrete units of matter that could help us better understand the electrical equivalent of ferromagnetism. Called hysterons, these nano-scaled stacks of molecules act like independent particles in a crowd, solving a long standing mystery while laying the groundwork for advanced

On February 11th, 2016, scientists at the Laser Interferometer Gravitational-wave Observatory (LIGO) made history when they announced the first detection of gravitational waves. Originally predicted made by Einstein’s Theory of General Relativity a century prior, these waves are essentially ripples in space-time that are formed by major astronomical events – such as the merger of

Scientists have experimentally confirmed the existence of strange new uranium compounds – and they predict some could even achieve superconductivity close to room temperature. Superconducting materials are able to shuttle electricity without any resistance – an incredible feat that could revolutionise our energy use. But so far researchers have only found superconductivity in a handful
