Scientists spot erupting jets of material as black hole tears a star apart
Astronomers have for the first time directly imaged a fast-moving jet of material ejected as a supermassive black hole consumed a star. Scientists have previously detected a few cases of black holes destroying stars, but this is the first time they have imaged a bright jet of material from the event.

Discovery in the sky with nanodiamonds
A faint and mysterious stream of microwaves emanating from star systems far out in the Milky Way could be caused by tiny diamonds, new research has suggested. For decades scientists have been able to measure this ‘glow' of microwave light, dubbed the anomalous microwave emission (AME), coming from a number of regions in the night sky, but have yet to identify its exact source.

Magnetic field collisions around Saturn reveal planetary differences
Magnetic field collisions around Saturn reveal planetary differences
Magnetic reconnection - the explosive reconfiguration of two magnetic fields - occurs differently around Saturn than around Earth, according to new findings from the international Cassini mission involving UCL researchers. On Earth, the collisions which create aurora are only seen on the boundary between Earth's magnetic field and the magnetic field in interplanetary space.

Graphene paves the way to faster high-speed communications
Graphene paves the way to faster high-speed communications
Researchers have created a technology that could lead to new devices for faster, more reliable ultra-broad bandwidth transfers, and demonstrated how electrical fields boost the non-linear optical effects of graphene, a two-dimensional form of carbon.  Graphene never ceases to surprise us when it comes to optics and photonics.

Supercomputers provide new window into the life and death of the neutron
Experiments that measure the lifetime of neutrons reveal a perplexing and unresolved discrepancy. While this lifetime has been measured to a precision within 1 percent using different techniques, apparent conflicts in the measurements offer the exciting possibility of learning about as-yet undiscovered physics.

Multiple metals - and possible signs of water - found in unique exoplanet
An international team of researchers have identified 'fingerprints' of multiple metals in one of the least dense exoplanets ever found.  The detection of a trace element such as lithium in a planetary atmosphere is a major breakthrough. Nikku Madhusudhan The team, from the University of Cambridge and the Instituto de Astrofísica de Canarias (IAC) in Spain used the Gran Telescopio Canarias (GTC) to observe WASP-127b, a giant gaseous planet with partly clear skies and strong signatures of metals in its atmosphere.

Scientists use a photonic quantum simulator to make virtual movies of molecules vibrating
Scientists use a photonic quantum simulator to make virtual movies of molecules vibrating
Scientists have shown how an optical chip can simulate the motion of atoms within molecules at the quantum level, which could lead to better ways of creating chemicals for use as pharmaceuticals. An optical chip uses light to process information, instead of electricity, and can operate as a quantum computing circuit when using single particles of light, known as photons.

Improving drug treatments with natural products
Turmeric, shrimp shells, beeswax and cocoa butter are being used to improve the effectiveness of drugs and reduce side effects when treating a range of diseases including cancer and diabetes. Research is being carried out at the University of Nottingham Malaysia to discover how these ‘natural products' can improve the ways drugs are delivered and their efficiency, whilst also minimising any side effects.

Dementia friendly swimming sessions help patients and carers, study finds
Specially organised ‘dementia friendly' swimming sessions can be beneficial to people with dementia and their carers, according to a new study by researchers at the University of Nottingham and the Institute of Mental Health. The team set out to find out what impact swimming sessions have on the lives of people with dementia and how they affect the experience of their carers.

Stars formed only 250 million years after the Big Bang
Stars in a galaxy 13.28 billion light years away formed only 250 million years after the Big Bang, finds a team of international astronomers led by groups at UCL and Osaka Sangyo University in Japan. The discovery shows that stars in the galaxy - called MACS1149-JD1 - formed at an unexpectedly early stage in the age of the Universe and the new observations break the team's own record for detecting the most distant known source of oxygen.

Could a Multiverse be hospitable to life?
Could a Multiverse be hospitable to life?
A Multiverse - where our Universe is only one of many - might not be as inhospitable to life as previously thought, according to new research. Questions about whether other universes might exist as part of a larger Multiverse, and if they could harbour life, are burning issues in modern cosmology. Now new research led by Durham University, UK, and Australia's University of Sydney, Western Sydney University and the University of Western Australia, has shown that life could potentially be common throughout the Multiverse, if it exists.

X-rays from tabletop lasers allows scientists to peer through the ’water window’
Studying the fleeting actions of electrons in organic materials will now be much easier, thanks to a new method for generating fast X-rays. The technique means advanced measurements of fast reactions will now be possible in physics labs around the world, without having to wait to use expensive and scarce equipment.

Gravitational waves help unravel mystery of gamma ray bursts in space
The data collected during historic first detection of a binary neutron star collision is helping astrophysicists further unravel the mystery of gamma-ray bursts in space. Gamma-ray bursts are extremely energetic cosmological events in which massive amounts of gamma-ray light, hundreds of times brighter than a supernova, are released.

Fleet of spacecraft spot long-sought-after process in the Earth’s magnetic field
A NASA mission has discovered an important process explaining the fate of energy contained in the turbulent magnetic fields surrounding the Earth. The phenomenon, discovered by NASA's four-spacecraft Magnetospheric Multiscale (MMS) mission, is small but provides crucial insight into turbulent plasmas.
