University of Glasgow researchers prepare for next gravitational wave observing run
Researchers from the University of Glasgow's School of Physics & Astronomy are preparing for the next observing run of the international LIGO-Virgo-KAGRA (LVK) network of gravitational-wave detectors. The LVK collaboration consists of scientists across the globe who use a network of observatories-LIGO in the United States, Virgo in Europe, and KAGRA in Japan-to search for gravitational waves, or ripples in space-time, generated by colliding black holes and other extreme cosmic events.

JUICE magnetometer passes fitness tests and is ready to take data
The magnetometer instrument on the JUpiter ICy moons Explorer (JUICE) spacecraft has been rigorously tested and is ready to fulfil its mission. The magnetometer instrument (J-MAG), led by Imperial College London researchers, consists of three sensors, all of which were shown to be operating well. The deployment also marks the first time a quantum interference sensor - a precise but delicate technology - has been used beyond Earth orbit.

Shaping the technologies of the future
A new method of controlling the shape of tiny particles about one tenth of the width of human hair could make the technology that powers our daily lives more stable and more efficient, scientists claim. The process, which transforms the structure of microscopic semiconductor materials known as quantum dots, provides industry with opportunities to optimise optoelectronics, energy harvesting, photonics, and biomedical imaging technologies, according to the Cardiff University-led team.

Shining ring around black holes recreated in the lab
Researchers have created a spinning disc of plasma in a lab, mimicking discs found around black holes and forming stars. The experiment more accurately models what happens in these plasma discs, which could help researchers discover how black holes grow and how collapsing matter forms stars. As matter approaches black holes it heats up, becoming plasma - a fourth state of matter consisting of charged ions and free electrons.

Sustainable solar cell material shown to be highly promising for medical imaging
Using X-rays to see inside the human body has revolutionised non-invasive medical diagnostics. However, the dose of X-rays required for imaging is far higher than background levels, due to the poor performance of the detector materials currently available. This can cause harm to patients, and in some cases even cancer.

Signs that a rocky exoplanet could have an atmosphere detected by JWST
Scientists working with the James Webb Space Telescope say new data potentially shows water vapour around a rocky exoplanet - a first if confirmed. However, the water signature may also be coming from the star itself, so additional observations are needed. Water vapour has been seen on gaseous exoplanets before, but to date no atmosphere has been detected around a rocky exoplanet - defined as those with sizes less than or equal to 1.4x Earth's radius.

Most massive touching stars ever found will eventually collide as black holes
Two massive touching stars in a neighbouring galaxy are on course to become black holes that will eventually crash together, generating waves in the fabric of space-time, according to a new study by researchers at UCL and the University of Potsdam. The study, accepted for publication in the journal Astronomy & Astrophysics , looked at a known binary star (two stars orbiting around a mutual centre of gravity), analysing starlight obtained from a range of groundand space-based telescopes.

Intelligent membranes with memories make next-generation smart filters
Researchers from the National Graphene Institute (NGI) have made 'intelligent' membranes whose 'memory' can be used in areas like smart separation technology, wound management, drug delivery, sensors and memory devices. "The history of membrane development spans more than 100 years and has led to a revolution in industrial separation processes," says Professor Rahul Raveendran Nair , Carlsberg/Royal Academy of Engineering Research Chair and study team leader.

Researchers team up with NASA to launch new citizen science study
The cosmos is roaring with activity produced by the fourth state of matter - and now we can listen to it. Contrary to popular belief, space isn't a total vacuum - it's actually full of activity, with 99.999% of the universe's matter found in the form of the mysterious fourth state of matter: plasma.

Wonder material graphene claims yet another superlative
In a paper published in Nature this week (13 Apr 2023), researchers from The University of Manchester report record-high magnetoresistance that appears in graphene under ambient conditions. Materials that strongly change their resistivity under magnetic fields are highly sought for various applications and, for example, every car and every computer contain many tiny magnetic sensors.

Jupiter icy moon explorer prepares to discover new worlds
A Jupiter-exploring mission, which includes hardware provided by UCL scientists, is due to take off tomorrow (Thursday 13 April)m and will investigate whether some of the planet's icy moons are home to conditions that could support life. The European Space Agency's Jupiter Icy Moons Explorer (JUICE) will spend eight years travelling to the Jupiter system.

Double-slit experiment that proved the wave nature of light explored in time
Imperial physicists have recreated the famous double-slit experiment, which showed light behaving as particles and a wave, in time rather than space. The experiment relies on materials that can change their optical properties in fractions of a second, which could be used in new technologies or to explore fundamental questions in physics.

Tiny materials have huge solar energy applications
Tiny materials one hundred thousand times smaller than the width of a strand of hair could be used to improve solar cell technology. A study published this month in Advanced Materials shows that materials as small as 1.2 nanometres across could function in solar cells, which harvest energy from the sun.

Nanorippled graphene becomes a catalyst
A team of researchers led by Prof. Andre Geim from the National Graphene Institute (NGI) have discovered that nanoripples in graphene can make it a strong catalyst, contrary to general expectations that the carbon sheet is as chemically inert as the bulk graphite from which it is obtained. Published this week in the Proceedings of the National Academy of Sciences (PNAS), the research has shown that graphene with nanoscale corrugations of its surface can accelerate hydrogen splitting as well as the best metallic-based catalysts.

A new way to create high-energy ions could speed up their applications in treating cancer and probing the fundamental nature of matter. The new technique, created by researchers at Imperial College London with collaborators in Japan and Germany, will help deliver beams of ions that could treat cancers with high doses of more targeted radiation.

Edible electronics: how a seaweed second skin could transform health and fitness sensor tech
Scientists at the University of Sussex have successfully trialed new biodegradable health sensors that could change the way we experience personal healthcare and fitness monitoring technology. The team at Sussex have developed the new health sensors - such as those worn by runners or patients to monitor heart rate and temperature - using natural elements like rock salt, water and seaweed, combined with graphene.

Stick to your lane: hidden order in chaotic crowds
Mathematical research brings new understanding of crowd formation and behaviour. Have you ever wondered how pedestrians -know- to fall into lanes when they are moving through a crowd, without the matter being discussed or even given conscious thought? A new theory developed by mathematicians at the University of Bath led by Professor Tim Rogers explains this phenomenon, and is able to predict when lanes will be curved as well as straight.

Astronomers measure the heartbeat of spinning stars
An international team of scientist have used the MeerKAT radio telescope to observe the pulsing heartbeat of the universe as neutron stars are born and form swirling lightning storms which last for millions of years. Radio pulsars are spinning neutron stars from which we can observe flashes of radio waves in the manner of light pulses from a lighthouse.
