New results deal a blow to the theoretical sterile neutrino | University of Cambridge
Results from a global science experiment have cast doubt on the existence of a theoretical particle beyond the Standard Model. The results were gathered by an international team at the MicroBooNE experiment in the United States, with leadership from a UK team including researchers from the. The two most likely explanations for anomalies that were seen in two previous physics experiments: one which suggests a sterile neutrino, and one which points at limitations in those experiments, have been ruled out by MicroBooNE.

Cambridge physicists announce results that boost evidence for new fundamental physics | University of Cambridge
Results announced by the LHCb experiment at CERN have revealed further hints for phenomena that cannot be explained by our current theory of fundamental physics. The fact that we've seen the same effect as our colleagues did in March certainly boosts the chances that we might genuinely be on the brink of discovering something new Harry Cliff In March 2020, the same experiment released evidence of particles breaking one of the core principles of the Standard Model - our best theory of particles and forces - suggesting the possible existence of new fundamental particles and forces.

Have we detected dark energy? Cambridge scientists say it’s a possibility
Dark energy, the mysterious force that causes the universe to accelerate, may have been responsible for unexpected results from the XENON1T experiment, deep below Italy's Apennine Mountains. It was surprising that this excess could in principle have been caused by dark energy rather than dark matter.

On the hunt for ’hierarchical’ black holes
Black holes, detected by their gravitational wave signal as they collide with other black holes, could be the product of much earlier parent collisions. Such an event has only been hinted at so far, but scientists at the University of Birmingham in the UK, and Northwestern University in the US, believe we are getting close to tracking down the first of these so-called 'hierarchical' black holes.

Planets form in binary systems without getting crushed
Astronomers have developed the most realistic model to date of planet formation in binary star systems. Planet formation in binary systems is more complicated, because the companion star acts like a giant eggbeater, dynamically exciting the protoplanetary disc Roman Rafikov The researchers, from the University of Cambridge and the Max Planck Institute for Extra-terrestrial Physics, have shown how exoplanets in binary star systems - such as the 'Tatooine' planets spotted by NASA's Kepler Space Telescope - came into being without being destroyed in their chaotic birth environment.

Scientists solve 40-year mystery over Jupiter’s X-ray aurora
A research team co-led by UCL has solved a decades-old mystery as to how Jupiter produces a spectacular burst of X-rays every few minutes. The X-rays are part of Jupiter's aurora - bursts of visible and invisible light that occur when charged particles interact with the planet's atmosphere. A similar phenomenon occurs on Earth, creating the northern lights, but Jupiter's is much more powerful, releasing hundreds of gigawatts of energy, enough to briefly power all of human civilisation*.
