Cosmic physics mimicked on table-top as graphene enables Schwinger effect
Researchers at The University of Manchester have succeeded in observing the so-called Schwinger effect, an elusive process that normally occurs only in cosmic events. By applying high currents through specially designed graphene-based devices, the team - based at the National Graphene Institute - succeeded in producing particle-antiparticle pairs from a vacuum.

’Slushy’ magma ocean led to formation of the Moon’s crust
Scientists have shown how the freezing of a 'slushy' ocean of magma may be responsible for the composition of the Moon's crust. Cooling of the early magma ocean drove such vigorous convection that crystals remained suspended as a slurry, like the crystals in a slushy machine. Jerome Neufeld The scientists, from the University of Cambridge and the Ecole normale supérieure de Lyon, have proposed a new model of crystallisation, where crystals remained suspended in liquid magma over hundreds of millions of years as the lunar 'slush' froze and solidified.

Templating approach stabilises ’ideal’ material for alternative solar cells
Researchers have developed a method to stabilise a promising material known as perovskite for cheap solar cells, without compromising its near-perfect performance. The researchers, from the University of Cambridge, used an organic molecule as a 'template' to guide perovskite films into the desired phase as they form.

’Wonder material’ phosphorene nanoribbons live up to hype in first demonstration
Phosphorene nanoribbons have been incorporated into new types of solar cells, dramatically improving the cells' efficiency, in a new study led by UCL and Imperial College London researchers. Phosphorene nanoribbons (PNRs) are ribbon-like strands of the 2D material phosphorous, which, similar to graphene, are made of single-atom-thick layers of atoms.

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).

New space telescope to uncover secrets of Universe’s origins
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.

Precision sieving of gases through atomic pores in graphene
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.

Colour-changing magnifying glass gives clear view of infrared light
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.

Putting the fizz into salty water
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.

Opinion: AI can reliably spot molecules on exoplanets - and might even discover new laws of Physics
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.
