Moths strike out in evolutionary arms race with sophisticated wing design
Moths strike out in evolutionary arms race with sophisticated wing design
Ultra-thin, super-absorbent and extraordinarily designed to detract attention, the wings of moths could hold the key for developing technological solutions to survive in a noisy world. As revealed in a new study published today in PNAS [date tbc], researchers from the University of Bristol have discovered the precise construction of moths wings that have enabled the species to evade its most troublesome predator in a 65 million-year-old evolutionary arms race.

Magnetic brain waves to detect injury and disease
Scientists at the University of Birmingham have developed a new sensor to measure weak magnetic signals in the brain, which has the potential to increase understanding of connectivity in the brain, and detect signs of traumatic brain injury, dementia and schizophrenia. Magnetic signals in the brain are measured by magnetoencephalography (MEG).

LIGO and Virgo announce new detections in updated gravitational-wave catalogue
The publication of a new catalogue of gravitational wave detections from the LIGO Scientific Collaboration and the Virgo Collaboration is providing valuable new insight into the workings of the universe. The catalog contains 39 new signals from black-hole or neutron-star collisions detected between April 1 and October 1, 2019, which more than triples the number of confirmed detections since the first detection of gravitational waves in September 2015.

Death by Spaghettification: Scientists Record Last Moments of Star Devoured by a Black Hole
A rare blast of light, emitted by a star as it is sucked in by a supermassive black hole, has been spotted by scientists using telescopes from around the world. The phenomenon, known as a tidal disruption event, is the closest flare of its kind yet recorded, occurring just 215 million light-years from Earth.

Upper limit for the speed of sound
Upper limit for the speed of sound
A research collaboration between the University of Cambridge, Queen Mary University of London and the Institute for High Pressure Physics in Troitsk has discovered the fastest possible speed of sound. The result - about 36 km per second - is around twice as fast as the speed of sound in diamond, the hardest known material in the world.

Squeezing light inside memory devices could help improve performance
Squeezing light inside memory devices could help improve performance
Researchers have developed a method to 'squeeze' visible light in order to see inside tiny memory devices. The technique will allow researchers to probe how these devices break down and how their performance can be improved for a range of applications. The team, led by the University of Cambridge, used the technique to investigate the materials used in random access memories, while in operation.

Detection of gravitational wave ’lensing’ could be some way off
Gravitational wave scientists looking for evidence of ‘lensing', in which the faintest gravitational wave signals become amplified, are unlikely to make these detections in the near future according to new analysis by scientists at the University of Birmingham. A team in the University's School of Physics and Astronomy and the Institute for Gravitational Wave Astronomy has analysed currently available gravitational wave data to predict that these elusive signals are likely to remain undetected by the instruments currently operated by the LIGO and Virgo Collaboration.

AI shows how hydrogen becomes a metal inside giant planets
Researchers have used a combination of AI and quantum mechanics to reveal how hydrogen gradually turns into a metal in giant planets. The existence of metallic hydrogen was theorised a century ago, but what we haven't known is how this process occurs Bingqing Cheng Dense metallic hydrogen - a phase of hydrogen which behaves like an electrical conductor - makes up the interior of giant planets, but it is difficult to study and poorly understood.

Where do black-hole parents meet? LIGO/Virgo may provide answers
Astrophysicists investigating gravitational-wave data from the far reaches of the Universe believe they may have found an explanation for a curious signal detected from the collision of two black holes. The signal, named GW190412, was picked up by the LIGO / Virgo detectors, which are set up to observe gravitational waves - the ripples in space and time caused by huge astronomical objects - and use them to make new discoveries about our Universe.
