Advances in x-ray imaging can help patients with breast cancer
A new x-ray imaging scanner to help surgeons performing breast tumour removal surgery has been developed by UCL experts. Most breast cancer operations are what are known as conserving surgeries, which remove the cancerous tumour rather than the whole breast. Second operations are often required if the margins (edges) of the extracted tissue are found to not be clear of cancer.

New research will disrupt solar and expedite efforts toward Net-Zero target
A team of researchers, led by chemists from the University of Bristol, has received significant funding from the UKRI to revolutionise the fabrication and application of photovoltaic devices, used to produce solar energy. Imagine a city in the near future where buildings have solar panels integrated into windows, cladding and rooftops - allowing urban areas to generate their own clean and renewable energy.

'Magnetic graphene' forms a new kind of magnetism
’Magnetic graphene’ forms a new kind of magnetism
Researchers have identified a new form of magnetism in so-called magnetic graphene, which could point the way toward understanding superconductivity in this unusual type of material. The researchers, led by the University of Cambridge, were able to control the conductivity and magnetism of iron thiophosphate (FePS 3 ), a two-dimensional material which undergoes a transition from an insulator to a metal when compressed.

Newly-developed material could lead to lighter, safer car designs
A new form of 3D-printed material made by combining commonly-used plastics with carbon nanotubes is tougher and lighter than similar forms of aluminium, scientists say. The material could lead to the development of safer, lighter and more durable structures for use in the aerospace, automotive, renewables and marine industries.

’Multiplying’ light could be key to ultra-powerful optical computers
New type of optical computing could solve highly complex problems that are out of reach for even the most powerful supercomputers. An important class of challenging computational problems, with applications in graph theory, neural networks, artificial intelligence and error-correcting codes can be solved by multiplying light signals, according to researchers from the University of Cambridge and Skolkovo Institute of Science and Technology in Russia.

Physicists finesse the storing of light to create rainbows of colour
Physicists at the University of Bath have found a way to use resonance to harness the energy of light more effectively inside microresonators. Last updated on Monday 8 February 2021 In nature, as in everyday life, we are surrounded by resonance - the phenomenon that describes how each object has a frequency that it prefers to vibrate at.

Holography ’quantum leap’ could revolutionise imaging
A new type of quantum holography which uses entangled photons to overcome the limitations of conventional holographic approaches could lead to improved medical imaging and speed the advance of quantum information science. A team of physicists from the University of Glasgow are the first in the world to find a way to use quantum-entangled photons to encode information in a hologram.

Magnetic waves explain mystery of Sun’s outer layer
A theory as to why the Sun's outer atmosphere differs in its chemical make-up from its inner layers has been confirmed by direct observation for the first time by scientists at UCL and the Italian Space Agency. The Sun's extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades.

UofG supports major quantum technology effort to solve universe’s mysteries
The University of Glasgow's James Watt School of Engineering is providing key expertise for a new project which has won funding from UK Research and Innovation (UKRI). The Quantum-enhanced Interferometry for New Physics project, led by Cardiff University, is one of seven projects which aim to transform our understanding of the universe.

Quantum tech to help weigh universe’s most elusive particle
Researchers are leading a £3.8 million project to develop quantum technology aimed at detecting the mass of a neutrino, the universe's most abundant but elusive particle of matter. UCL is playing a key role in three of the seven projects. Neutrinos are millions of times lighter than electrons and are poorly understood as they can pass through matter undetected.

Scientists to lead hunt for dark matter
Cardiff University scientists are to lead a consortium hoping to track down one of the most mysterious materials in the Universe - dark matter. The £5m Quantum-Enhanced Interferometry (QI) collaboration will use state-of-the-art quantum technology to shed more light on the material which makes up roughly 27 per cent of the Universe but has yet to be directly detected.

UofG researchers set out for New Horizons
Researchers from the University of Glasgow's College of Science & Engineering are sharing in new funding for adventurous, high-risk research. Four projects from three Schools have received support from the £25.5m New Horizons fund, administered by the Engineering and Physical Science Research Council (EPSRC).

How heavy is Dark Matter? Scientists radically narrow the potential mass range for the first time
How heavy is Dark Matter? Scientists radically narrow the potential mass range for the first time
Scientists have calculated the mass range for Dark Matter - and it's tighter than the science world thought. Their findings - due to be published in Physical Letters B in March - radically narrow the range of potential masses for Dark Matter particles, and help to focus the search for future Dark Matter-hunters.

Transforming detection with quantum-enabled radar
Radars are being installed at the top of an engineering building at the University of Birmingham as part of a demonstration intended to test and prove the precision of quantum-enabled radar detection capabilities. A key part of keeping everyday life secure is being able to detect dangerous or unsafe situations before they occur.

Hidden symmetry could be key to more robust quantum systems, researchers find
Researchers have found a way to protect highly fragile quantum systems from noise, which could aid in the design and development of new quantum devices, such as ultra-powerful quantum computers. Until we can find a way to make quantum systems more robust, their real-world applications will be limited Shovan Dutta The researchers, from the University of Cambridge, have shown that microscopic particles can remain intrinsically linked, or entangled, over long distances even if there are random disruptions between them.

Magnetic vortices come full circle
The first experimental observation of three-dimensional magnetic 'vortex rings' provides fundamental insight into intricate nanoscale structures inside bulk magnets and offers a fresh perspective for magnetic devices. One of the main puzzles was why these structures are so unexpectedly stable - like smoke rings, they are only supposed to exist as moving objects Claire Donnelly Magnets often harbour hidden beauty.

Quantum nanodiamonds may help detect disease earlier
The quantum sensing abilities of nanodiamonds can be used to improve the sensitivity of paper-based diagnostic tests, potentially allowing for earlier detection of diseases such as HIV, according to a study led by UCL researchers in the i-sense McKendry group. Paper-based lateral flow tests work the same way as a pregnancy test in that a strip of paper is soaked in a fluid sample and a change in colour - or fluorescent signal - indicates a positive result and the detection of virus proteins or DNA.

Moths strike out in evolutionary arms race with sophisticated wing design
Ultra-thin, super-absorbent and extraordinarily designed to detract attention, the wings of moths could hold the key for developing technological solutions to survive in a noisy world. As revealed in a new study published today in PNAS [date tbc], researchers from the University of Bristol have discovered the precise construction of moths wings that have enabled the species to evade its most troublesome predator in a 65 million-year-old evolutionary arms race.
