Dark Matter Experiment’s Central Component Takes a Deep Dive - Nearly a Mile Underground
This video chronicles the move of the LUX-ZEPLIN central detector, known as the time projection chamber, nearly a mile underground to the research cavern where it will be used to hunt for dark matter. (Credit: Matthew Kapust, Erin Broberg, and Nick Hubbard/Sanford Underground Research Facility) Q: How do you get a 5,000-pound, 9-foot-tall particle detector, designed to hunt for dark matter, nearly a mile underground? A: Very carefully.

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.

DESI Opens Its 5,000 Eyes to Capture the Colors of the Cosmos
This video highlights the components and statistics that make DESI, the Dark Energy Spectroscopic Instrument, unique. Installed on the Mayall Telescope at Kitt Peak National Observatory near Tucson, Arizona, DESI brings high-speed automation to its galaxy-mapping mission. In five years DESI will capture the light from 35 million galaxies and 2.4 million quasars to produce the largest 3D map of the universe.

Theorists discover the ’Rosetta Stone’ for neutrino physics
UChicago, Brookhaven, Fermilab scientists find new math identity while studying particle physics Usually the way things work is that mathematicians make math discoveries, and physicists borrow and adapt those ideas to explain the universe. But three physicists at the University of Chicago and two national laboratories have discovered a fundamental identity in linear algebra-based on studying particle physics.

Fast internet anytime and anywhere
Fast internet anytime and anywhere
The continuously growing need for higher data rates as well as globally available broadband internet requires innovative technology developments and the exploitation of a new electromagnetic spectrum. In the scope of R&D projects funded by the German Aerospace Center, researchers at the University of Stuttgart have developed a high-performance technology platform to exploit the frequency spectrum in the so-called E-band at 71-86 GHz.

Münster University chemists create new types of Lewis acids
Münster University chemists create new types of Lewis acids
Researchers at the University of Münster have developed a method which makes it possible to create three-coordinate Lewis superacids on the basis of phosphorus. Previously, it had not been possible to isolate this type of compound, either in a liquid or in a solid state, due to its extreme electrophilicity and the associated reactivity.

It takes two - a two-atom catalyst, that is - to make oxygen from water
The search for sustainable approaches to generating new fuels has brought scientists back to one of the most abundant materials on Earth - reddish iron oxide in the form of hematite, also known as rust. Researchers say rust has long been seen as a potentially attractive material for solar water splitting, a key process that plants employ in photosynthesis.

Atomic images reveal unusually many neighbors for some oxygen atoms
Atomic images reveal unusually many neighbors for some oxygen atoms
The identification of new chemical bonds is crucial for the design of new material structures. A team led by Jani Kotakoski at the University of Vienna and Jannik Meyer at the University of Tübingen has found unexpected new configurations of oxygen and nitrogen in graphene. Direct images of the actual atoms and the analysis of Life as we know it is based on just a handful of different types of atoms (called elements), among them carbon, nitrogen and oxygen.

Atomic force microscopy: new sensing element for high-speed imaging
Researchers at TU Wien have developed a new type of sensing element for atomic force microscopy, which enables a high measurement speed and can even image sensitive processes in living cells. High-definition images of minute objects are standard these days including the imaging of bacteria and viruses, and even molecules and individual atoms in extremely fine details.

Physicists shed new light on how liquids behave with other materials
Using a range of theoretical and simulation approaches, physicists from the University of Bristol have shown that liquids in contact with substrates can exhibit a finite number of classes of behaviour and identify the important new ones. Their findings, published in the Proceedings of the National Academy of Sciences (PNAS) , challenge the accepted wisdom on wetting and drying phase behaviour.

Quantum physics: ménage ŕ trois photon-style
Quantum physics: ménage ŕ trois photon-style
Physicists from UNIGE have discovered a new quantum property: by placing three pairs of photons in a network, it is possible to entangle them and create new ultra-strong correlations. Entanglement is one of the properties specific to quantum particles. When two photons become entangled, for instance, the quantum state of the first will correlate perfectly with the quantum state of the second, even if they are at a distance from one another.

Observation of the Resonance Frequencies of a Stable Torus of Fluid
Publication by Laboratoire de physique in Physical Review Letters on August 30, 2019. We report the first quantitative measurements of the resonance frequencies of a torus of fluid confined in a horizontal Hele-Shaw cell. By using the unwetting property of a metal liquid, we are able to generate a stable torus of fluid with an arbitrary aspect ratio.

Solving the Mystery of Quantum Light in Thin Layers
Solving the Mystery of Quantum Light in Thin Layers
A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna). It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material tungsten diselenide, it begins to glow in a highly unusual fashion.

Super light dampers for low tones
Super light dampers for low tones
A team of Empa acoustic researchers has built macroscopic crystal structures that use internal rotation to attenuate the propagation of waves. The method makes it possible to build very light and stiff materials that can also "swallow" low frequencies very well, as they report Communicatons. The world of crystals offers many interesting properties: crystals can strike electric sparks in disposable lighters, for example, they can produce polarized light and they can scatter bundled X-rays into thousands of individual reflexes that are refracted in all spatial directions.
