Researchers make most precise ever measurement of expanding Universe
Researchers make most precise ever measurement of expanding Universe
The Dark Energy Spectroscopic Instrument (DESI) collaboration, led by the Lawrence Berkeley National Laboratory in the US and involving UCL researchers, has made the most precise measurements to date of how fast the universe has expanded throughout its history. The analysis, based on the largest 3D map of the cosmos ever created with just the first year of data from DESI, confirms the basics of our current best model of the universe - with some tantalising areas to explore with more data.

’Cosmic Cannibals’ expel jets into space at 40% speed of light
Astronomers including those at the University of Warwick, have observed jets of matter being expelled into space at more than one-third the speed of light. These jets play an important role in the universe, from forming stars to transporting elements deep into space. Jets are produced by many different astronomical objects but studying them is hard, as they are so energetic.

Quantum imaging could create bright future for advanced microscopes
The unique properties of quantum physics could help solve a longstanding problem that prevents microscopes from producing sharper images at the smallest scales, researchers say. The breakthrough, which uses entangled photons to create a new method of correcting for image distortion in microscopes, could lead to improved classical microscope imaging of tissue samples to help advance medical research.

Astrophysicists unveil new phenomenon challenging textbook definition of white dwarf stars
Scientists have revealed why some white dwarfs mysteriously stop cooling - changing ideas on just how old stars really are, and what happens to them when they die. White dwarf stars are universally believed to be 'dead stars' that continuously cool down over time. However, in 2019, data from the European Space Agency's (ESA's) Gaia satellite discovered a population of white dwarf stars that have stopped cooling for more than eight billion years.

Scientists make nanoparticles dance to unravel quantum limits
Two optically trapped nanoparticles are coupled together by photons bouncing back and forth between mirrors The image shows two nanoparticles (green) trapped by optical tweezers / laser beams (red) and placed in between two mirrors (white) which forms an optical cavity (periodic blue blobs). The photons scattered by the nanoparticles (squiggly purple arrows) are trapped in the cavity, resulting in an interaction between the two nanoparticles (straight purple line).

Scientists closer to solving mysteries of universe after measuring gravity in quantum world
Scientists closer to solving mysteries of universe after measuring gravity in quantum world
Scientists are a step closer to unravelling the mysterious forces of the universe after working out how to measure gravity on a microscopic level. Experts have never fully understood how the force which was discovered by Isaac Newton works in the tiny quantum world. Even Einstein was baffled by quantum gravity and, in his theory of general relativity, said there is no realistic experiment which could show a quantum version of gravity.

Metal 'scar' found on dying star ingesting planets and asteroids
Metal ’scar’ found on dying star ingesting planets and asteroids
The unique signature of a star ingesting its surrounding planets and asteroids - a metal scar imprinted on the surface of a white dwarf star - has been found for the first time by a team including UCL researchers. White dwarfs are glowing embers of stars that have burned through all their hydrogen fuel.

Terahertz biosensor detects skin cancer with remarkable accuracy
Researchers have developed a revolutionary biosensor using terahertz (THz) waves that can detect skin cancer with exceptional sensitivity, potentially paving the way for earlier and easier diagnoses. Published in the IEEE Transactions on Biomedical Engineering , the study presents a significant advancement in early cancer detection, thanks to the collaboration of multidisciplinary teams from Queen Mary University of London and the University of Glasgow.

Astronomers uncover previously unknown source of star dust in rare supernova explosion
Astronomers uncover previously unknown source of star dust in rare supernova explosion
The first clear evidence of freshly baked star dust in a Type Ia supernova has been observed by an international team of astronomers. Monitored over the first three years after its explosion, the team claim the supernova - based in a spiral galaxy around 300 million lightyears away - is one of the most prolific dust-producing supernovae ever recorded.

Swarming cicadas, stock traders, and the wisdom of the crowd
Swarming cicadas, stock traders, and the wisdom of the crowd
The springtime emergence of vast swarms of cicadas can be explained by a mathematical model of collective decision-making with similarities to models describing stock market crashes. Pick almost any location in the eastern United States - say, Columbus Ohio. Every 13 or 17 years, as the soil warms in springtime, vast swarms of cicadas emerge from their underground burrows singing their deafening song, take flight and mate, producing offspring for the next cycle.

Lightest black hole or heaviest neutron star? Manchester astronomers uncover a mysterious object in Milky Way
An artist's impression of the system assuming that the massive companion star is a black hole. The brightest background star is its orbital companion, the radio pulsar PSR J0514-4002E. The two stars are separated by 8 million km and circle each other every 7 days. An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.

Astronomers detect oldest black hole ever observed
Astronomers detect oldest black hole ever observed
Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is 'eating' its host galaxy to death. It's a new era: the giant leap in sensitivity, especially in the infrared, is like upgrading from Galileo's telescope to a modern telescope overnight Roberto Maiolino The international team, led by the University of Cambridge, used the NASA/ESA/CSA James Webb Space Telescope (JWST) to detect the black hole, which dates from 400 million years after the big bang, more than 13 billion years ago.

Experiment could test quantum nature of large masses for the first time
Experiment could test quantum nature of large masses for the first time
An experiment outlined by a UCL-led team of scientists from the UK and India could test whether relatively large masses have a quantum nature, resolving the question of whether quantum mechanical description works at a much larger scale than that of particles and atoms. Quantum theory is typically seen as describing nature at the tiniest scales and quantum effects have not been observed in a laboratory for objects more massive than about a quintillionth of a gram, or more precisely 10^(-20)g.
