Lab-based dark energy experiment narrows search options for elusive force
An experiment to test a popular theory of dark energy has found no evidence of new forces, placing strong constraints on related theories. Dark energy is the name given to an unknown force that is causing the universe to expand at an accelerating rate. It is very exciting to be able to discover something about the evolution of the universe using a table-top experiment in a London basement.

Scientists uncover deep-rooted plumbing system beneath ocean volcanoes
Cardiff University scientists have revealed the true extent of the internal 'plumbing system' that drives volcanic activity around the world. An examination of pockets of magma contained within crystals has revealed that the large chambers of molten rock which feed volcanoes can extend to over 16 km beneath the Earth's surface.

Where in the universe can you find a black hole nursery?
Gravitational wave researchers at the University of Birmingham have developed a new model that could help astronomers track down the origin of heavy black hole systems in the Universe. Black holes are formed following the collapse of stars and possibly supernova explosions. These colossally dense objects are measured in terms of solar masses (M⊙) - the mass of our sun.

Global team of scientists finish assembling next-generation dark matter detector
The key component of the LUX-ZEPLIN experiment is ready to be sealed and lowered nearly 1.5 km underground, where it will search for dark matter. Dark matter is a mysterious form of matter thought to make up around 85% of the mass of the universe. However, because it is predicted to interact only very weakly with ordinary matter, it has so far not been detected.

Artificial tongue could have whisky counterfeiting licked
An artificial 'tongue' which can taste subtle differences between drams of whisky could help cut down on the trade in counterfeit alcohol, scientists say. In a new paper published today in the Royal Society of Chemistry's journal Nanoscale, Scottish engineers describe how they built the tiny taster, which exploits the optical properties of gold and aluminium to test the tipples.

Image of quantum entanglement
For the first time ever, physicists have managed to take a photo of a strong form of quantum entanglement called Bell entanglement - capturing visual evidence of an elusive phenomenon which a baffled Albert Einstein once called 'spooky action at a distance'. Two particles which interact with each other - like two photons passing through a beam splitter, for example - can sometimes remain connected, instantaneously sharing their physical states no matter how great the distance which separates them.

Quantum sensor breakthrough using naturally occurring vibrations in artificial atoms
A team of scientists, led by the University of Bristol, have discovered a new method that could be used to build quantum sensors with ultra-high precision. When individual atoms emit light, they do so in discrete packets called photons. When this light is measured, this discrete or 'granular' nature leads to especially low fluctuations in its brightness, as two or more photons are never emitted at the same time.

Light touch to improve rheumatoid arthritis diagnosis
A new way of detecting rheumatoid arthritis using infrared light could offer an objective way of diagnosing the disease and monitoring treatment effectiveness, a University of Birmingham study shows. The rapid, non-invasive technique could help clinicians diagnose the disease earlier, and assess how effectively the selected treatment is controlling the progression of the disease.

New Semiconductor Technology for Future Data Communications
Researchers have developed world-leading Compound Semiconductor (CS) technology that can drive future high-speed data communications. A team from Cardiff University worked to innovate an ultrafast and highly sensitive 'avalanche photodiode' (APD) that creates less electronic 'noise' than its silicon rivals.

Chameleon Theory could change our thoughts on gravity
Einstein's theory of General Relativity is world famous - but it might not be the only way to explain how gravity works and how galaxies form. Physicists at Durham University created huge supercomputer simulations of the universe to test an alternative theory. Our researchers found that f(R)-gravity - a so-called Chameleon Theory - could also explain the formation of structures in the cosmos.

Generation and sampling of quantum states of light in a silicon chip
Scientists from the University of Bristol and the Technical University of Denmark have found a promising new way to build the next generation of quantum simulators combining light and silicon micro-chips. In the roadmap to develop quantum machines able to compete and overcome classical supercomputers in solving specific problems, the scientific community is facing two main technological challenges.

Mini ’magic’ MRI scanner could diagnose knee injuries more accurately
Researchers at Imperial College London have developed a prototype mini MRI scanner that fits around a patient's leg. The team say the device - which uses so-called 'magic angle' effect - could potentially help diagnose knee injuries more quickly, and more accurately. Knee injuries affect millions of people - and MRI scans are crucial to diagnosing the problem Dr Karyn Chappell Study author In a proof-of-concept study using animal knees, the results suggest the technology could be used to show all the structures of the knee.

Identifies Fukushima reactor material in environment
Through the analysis of specific fallout particles in the environment, a joint UK-Japan team of scientists has uncovered new insights into the sequence of events that led to the Fukushima nuclear accident in March 2011. The multi-organisation research, led by Dr Peter Martin and Professor Tom Scott from the University of Bristol's South West Nuclear Hub in collaboration with scientists from Diamond Light Source, the UK's national synchrotron facility, and the Japan Atomic Energy Agency (JAEA), has been published today .

Researchers harness AI to combat colon cancer
Engineers have shown that it is technically possible to use an AI system to guide a tiny robotic capsule inside the colon to take microultrasound images. Known as a 'Sonopill', the device could spell the end for painful endoscopic examinations for patients, where a semi-rigid scope is passed into the bowel.

3D magnetic interactions could lead to new forms of computing
A new form of magnetic interaction which pushes a formerly two-dimensional phenomenon into the third dimension could open up a host of exciting new possibilities for data storage and advanced computing, scientists say. In a new paper published today , a team led by physicists from the University of Glasgow describe how they have been found a new way to successfully pass information from a series of tiny magnets arrayed on an ultrathin film across to magnets on a second film below.
