Switching 'spin' on and off (and up and down) in quantum materials at room temperature
Switching ’spin’ on and off (and up and down) in quantum materials at room temperature
Researchers have found a way to control the interaction of light and quantum -spin- in organic semiconductors, that works even at room temperature. These new materials hold great promise for completely new applications, since we've been able to remove the need for ultra-cold temperatures Sebastian Gorgon Spin is the term for the intrinsic angular momentum of electrons, which is referred to as up or down.

Making molecules dance to our tune reveals what drives their first movements
Making molecules dance to our tune reveals what drives their first movements
Bringing ultrafast physics to structural biology has revealed the dance of molecular -coherence- in unprecedented clarity. How molecules change when they react to stimuli such as light is fundamental in biology, for example during photosynthesis. Scientists have been working to unravel the workings of these changes in several fields, and by combining two of these, researchers have paved the way for a new era in understanding the reactions of protein molecules fundamental for life.

New measurement of particle wobble hints at new physics
New measurement of particle wobble hints at new physics
A new, ultraprecise measurement of the subatomic muon particle's anomalous magnetic moment, conducted at US-based Fermilab and involving researchers from UCL, reinforces a discrepancy between theory and experiment that physicists can't explain, potentially hinting at new physics. The latest results, submitted to Physical Review Letters , reinforce previous measurements of the muon's magnetic moment conducted by the Muon g-2 collaboration, the international research team operating the experiment.

Gravitational waves may reveal nature of dark matter
Gravitational waves may reveal nature of dark matter
Observations of gravitational waves from merging black holes may reveal new insights about dark matter, suggests a new study from a UCL-led international team. The study, presented at the 2023 National Astronomy Meeting in Cardiff and now published in the journal Physical Review D , used computer simulations to study the production of gravitational wave signals in simulated universes with different kinds of dark matter.

Can rainbows monitor the environment?
Can rainbows monitor the environment?
New nanotechnology may make it easier to identify the chemical composition of impurities and their geometrical shape in samples of air, liquid and live tissue. Using conventional testing techniques, it can be challenging - sometimes impossible - to detect harmful contaminants such as nano-plastics, air pollutants and microbes in living organisms and natural materials.

Scientists caught Hofstadter’s butterfly in one of the most ancient materials on Earth
Researchers in the National Graphene Institute (NGI) at The University of Manchester have revisited one of the most ancient materials on Earth - graphite, and discovered new physics that has eluded the field for decades. Despite being made entirely of layers of carbon atoms arranged in a honeycomb pattern, natural graphite is not as simple as one may think.

Two-faced star exposed in first for astronomy
An unusual white dwarf star is made of hydrogen on one side and helium on the other. In a first for white dwarfs, the burnt-our cores of dead stars, astronomers from institutions including the California Institute of Technology (Caltech) and the University of Warwick have discovered that at least one member of this cosmic family is two faced.

Webb sees carbon-rich dust grains in the first billion years of cosmic time
For the first time, the James Webb Space Telescope has observed the chemical signature of carbon-rich dust grains in the early universe. Similar observational signatures have been observed in the much more recent universe, and have been attributed to complex, carbon-based molecules known as polycyclic aromatic hydrocarbons (PAHs).

Limiting loss in leaky fibres
Limiting loss in leaky fibres
A theoretical understanding of what makes some hollow-core optical fibres more efficient than others will inspire the design of new low-loss fibres. Immense progress has been made in recent years to increase the efficiency of optical fibres through the design of cables that allow data to be transmitted both faster and at broader bandwidths.

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
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.
