Turbocharged data analysis could prevent gravitational wave computing crunch
A new method of analysing the complex data from massive astronomical events could help gravitational wave astronomers avoid a looming computational crunch. Researchers from the University of Glasgow have used machine learning to develop a new system for processing the data collected from detectors like the Laser Interferometer Gravitational-Wave Observatory (LIGO).

The NASA-led James Webb Space Telescope, which includes hardware designed and built at UCL and which will image the very first stars to shine in the Universe, is scheduled to be launched into space later this month. The telescope, one of the great space observatories following Hubble, will be launched on-board the Ariane rocket from Europe's spaceport in French Guiana on or after Friday 24 December.

By crafting atomic-scale holes in atomically thin membranes, it should be possible to create molecular sieves for precise and efficient gas separation, including extraction of carbon dioxide from air, University of Manchester researchers have found. If a pore size in a membrane is comparable to the size of atoms and molecules, they can either pass through the membrane or be rejected, allowing separation of gases according to their molecular diameters.

Revolutionising imaging through an optical fibre the width of a human hair
A new imaging technique, allowing 3D imaging at video rates through a fibre the width of a human hair, could transform imaging for a wide range of applications in industrial inspection and environmental monitoring. In the longer term the technique could be further developed for applications in medical imaging.

By trapping light into tiny crevices of gold, researchers have coaxed molecules to convert invisible infrared into visible light, creating new low-cost detectors for sensing. It's like listening to slow-rippling earthquake waves by colliding them with a violin string to get a high whistle that's easy to hear, and without breaking the violin Jeremy Baumberg Detecting light beyond the visible red range of our eyes is hard to do, because infrared light carries so little energy compared to ambient heat at room temperature.

A new study sheds light on the way salty water acts in deep-sea aquifers, paving the way for further research into carbon storage deep beneath the seabed. Pools of salty water (brine) trapped beneath the seabed offer an unparalleled opportunity to sequester carbon and keep it trapped for millennia. Yet research in this area remains rudimentary, as little is known about the way sodium chloride (salt) behaves when it-s combined with carbon dioxide several kilometres beneath the surface of the earth, where conditions of heat and pressure are extreme.

Research into the logic behind AI shows that algorithms think in reliable and scientific ways that could help us learn undiscovered laws of physics, say PhD candidate Kai Hou Yip and Dr Quentin Changeat (both UCL Physics & Astronomy). Do you know what the Earth's atmosphere is made of? You'd probably remember it's oxygen, and maybe nitrogen.

Space dust analysis could solve mystery of the origins of Earth’s water
An international team of scientists may have solved a key mystery about the origins of the Earth's water, after uncovering persuasive new evidence pointing to an unlikely culprit - the Sun. In a new paper published today in the journal Nature Astronomy , a team of researchers from the UK, Australia and America describe how new analysis of an ancient asteroid suggests that extraterrestrial dust grains carried water to Earth as the planet formed.

Fundamental particles modelled in beam of light
Scientists at the University of Birmingham have succeeded in creating an experimental model of an elusive kind of fundamental particle called a skyrmion in a beam of light. The breakthrough provides physicists with a real system demonstrating the behaviour of skyrmions, first proposed 60 years ago by a University of Birmingham mathematical physicist, Professor Tony Skyrme.

Research casts new light on processes behind solar eruptions
New research into the powerful magnetic fields which form inside the sun and cause violent eruptions could help predict solar flares. Mathematicians and astrophysicists from the UK and Italy have comprehensively modelled the emergence of twisted magnetic fields into the solar atmosphere, and verified their models through observations - a breakthrough in scientific understanding of the process by which solar flares occur.

An international team involving UCL researchers has developed a computer model of the powerful jets released by the M87 black hole, matching the observations of astronomers and providing new support for the theory of general relativity. The black hole launches a jet of plasma at very close to the speed of light, a so-called relativistic jet, over a distance of more than 6,000 light years (that is, the jet extends beyond the giant galaxy in which the black hole resides).

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.

New era of physics uncovered by Neutrino experiment’s first results
A major new physics experiment has used four complementary analyses to show no signs of a theorised fourth kind of neutrino known as the sterile neutrino. Its existence is considered a possible explanation for anomalies seen in previous physics experiments. New results from the MicroBooNE experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory deal a blow to a theoretical particle known as the sterile neutrino.
