Particle detector for hunting dark matter installed a mile underground
Particle detector for hunting dark matter installed a mile underground
The central component of LUX-ZEPLIN (LZ) - the largest direct-detection dark matter experiment in the US - has been slowly lowered 4,850 feet down a shaft formerly used in gold-mining operations by a team involving UCL physicists. Although dark matter accounts for about 27 percent of the universe, we do not know what it is made of and experiments have yet to make direct contact with a particle - it has only been detected through its gravitational effects on normal matter.

Mapping the universe in extraordinary detail using UCL lenses
A three-dimensional map of the Universe that reaches deeper in space and time than ever before is one step closer as final testing begins on the Dark Energy Spectroscopic Instrument (DESI), designed and built in part by UCL physicists. From early 2020, DESI will observe the light from 35 million distant galaxies and 2.4 million quasars over five years to precisely map their distance from Earth and gauge how quickly they are moving away from us.

Scientists Observe Year-long Plateaus in Decline of Type Ia Supernova Light Curves
A team of scientists, including a researcher from the University of Birmingham, has discovered that the fading of infrared light following Type Ia supernovae explosions can be interrupted, with brightness staying the same for up to a year. This is a surprising finding as astronomers had expected that the light curve would not only continue decreasing but even experience a sharp drop, rather than flattening into a plateau.

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.

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
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.

Chameleon Theory could change our thoughts on gravity
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.
