First evidence for new class of gravitational waves which could unveil origin of the Universe
After 25 years of observations, an international team of astronomers has seen the first evidence of ultra-low-frequency gravitational waves. The waves are expected to come from pairs of supermassive black holes found in the centres of merging galaxies and the discovery could hold answers about the formation and evolution of the Universe and the galaxies that populate it, including our own Milky Way.

Experiments reveal water can ’talk’ to electrons in graphene
For the last 20 years, scientists have been puzzled by how water behaves near carbon surfaces. It may flow much faster than expected from conventional flow theories or form strange arrangements such as square ice.

New hope in search for dark matter as most sensitive instrument of its kind begins first science run
The search for extremely light particles which are thought to be the building blocks of dark matter is underway. An international team of scientists, led by Deutsches Elektronen-Synchrotron (DESY) and drawing on expertise from Cardiff University, have started the Any Light Particle Search (ALPS II) experiment.

New gravitational waves observation run to reveal more of the universe's secrets
New gravitational waves observation run to reveal more of the universe’s secrets
A new observation run to search for ripples in space-time generated by colliding black holes and other extreme cosmic events will take gravitational wave astronomy to the next level, scientists claim. Upgraded instruments, some of which use Cardiff University-built technology, new and even more accurate signal models, and more advanced data analysis methods mean the 20-month observation will be the most sensitive search for gravitational waves to date.

Origin of superfast solar wind found by spacecraft flying close to the Sun
The Parker Solar Probe has flown close enough to the surface of the Sun to detect the fine structure of the solar wind close to where it is generated. In a paper published today in the journal Nature , a team of researchers including from Imperial College London used data from NASA's Parker Solar Probe to explain how the solar wind is capable of surpassing speeds of one million miles per hour.

Cell 'skeletons' built with strands of DNA
Cell ’skeletons’ built with strands of DNA
The tiny tubes and thread-like structures that give cells their shape and help determine their function have been artificially re-created using strands of DNA in a study led by UCL researchers. The research, published in Nature Communications , represents a key step towards synthetic "smart cells" that could be used to sense diseases, deliver drugs or repair damaged cells inside the body.

What made the brightest cosmic explosion of all time so exceptional?
What made the brightest cosmic explosion of all time so exceptional?
Last year, telescopes registered the brightest cosmic explosion of all time. Astrophysicists can now explain what made it so dazzling. Few cosmic explosions have attracted as much attention from space scientists as the one recorded on October 22 last year and aptly named the Brightest of All Time (BOAT).

Early universe crackled with bursts of star formation, Webb Telescope shows
Among the most fundamental questions in astronomy is: How did the first stars and galaxies form? The James Webb Space Telescope (JWST), a partnership between NASA, the European Space Agency and the Canadian Space Agency, is already providing new insights into this question.

Scientists propose revolution in complex systems modelling with quantum technologies
Scientists have made a significant advancement with quantum technologies that could transform complex systems modelling with an accurate and effective approach that requires significantly reduced memory. Complex systems play a vital role in our daily lives, whether that be predicting traffic patterns, weather forecasts, or understanding financial markets.

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
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
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
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
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.

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.
