Attitudes towards green energy affected by fracking debate
Public attitudes towards some new low-carbon technologies could be negatively influenced by the fracking debate, new research from Cardiff University suggests. A team from the University's School of Psychology found that acceptance of deep geothermal energy - technology to harness the heat beneath the Earth's crust - was affected by the backdrop of controversy and opposition towards fracking for oil and gas.

New form of ice is like a snapshot of liquid water
A collaboration between scientists at Cambridge and UCL has led to the discovery of a new form of ice that more closely resembles liquid water than any other and may hold the key to understanding this most famous of liquids. Our discovery of MDA raises many questions on the very nature of liquid water and so understanding MDA-s precise atomic structure is very important Michael Davies The new form of ice is amorphous.

Researchers devise a new path toward ’quantum light’
Researchers have theorised a new mechanism to generate high-energy -quantum light-, which could be used to investigate new properties of matter at the atomic scale. The researchers, from the University of Cambridge, along with colleagues from the US, Israel and Austria, developed a theory describing a new state of light, which has controllable quantum properties over a broad range of frequencies, up as high as X-ray frequencies.

Discovery of new ice may change understanding of water
Researchers at UCL and the University of Cambridge have discovered a new type of ice that more closely resembles liquid water than any other known ices and that may rewrite our understanding of water and its many anomalies. The newly discovered ice is amorphous - that is, its molecules are in a disorganised form, not neatly ordered as they are in ordinary, crystalline ice.

The world’s most intense high-energy neutrino beam measures the ’unmeasurable’ proton for the first time
Once deemed -unmeasurable- protons have been measured using a high-energy neutrino beam. The first statistically significant study to measure the size of protons using neutrinos is published today, after years of data-gathering · The proton radius seen by the neutrinos is 0.73 femtometres - a quadrillionth of one metre · Measurements were made by firing high-energy neutrino beams at protons for a decade in the Main INjector ExpeRiment for v-A (MINERvA) experiment, at the Fermi National Accelerator Laboratory (Fermilab), Illinois, USA Protons have puzzled scientists for decades.

Long-term memory in 2D nanofluidic channels
Published in Science , a collaboration between teams from the National Graphene Institute (NGI) at The University of Manchester , and the É cole Normale Sup é rieure (ENS), Paris, demonstrated the Hebbian learning in artificial nanochannels, where the channels showed short and long term memory. Hebbian learning is a technical term introduced in 1949 by Donald Hebb, describing the process of learning by repetitively doing an action.

Scientists open new window on the physics of glass formation
Research from an international team of scientists has cast new light on the physics of vitrification - the process by which glass forms. Their findings, which centre on analysis of a common feature of glasses called the boson peak, could help pave the way for new developments in materials science. The peak can be observed in glass when special equipment is used to study the vibrations of its constituent atoms, where it spikes in the terahertz range.

Method to preserve entanglement could enable new quantum tech
An international team of researchers has developed a new method of overcoming a key challenge for the development of future quantum tech. In a new paper published in the journal Physical Review X Quantum, the researchers describe how they may have solved a key problem for quantum technologies by keeping particles entangled in previously impossible conditions.

Astronomical collaboration maps the structure of our Galaxy’s magnetic field
Almost a decade after starting observations of the sky in the northern hemisphere in the microwave range, the QUIJOTE Collaboration has presented the most accurate description we have of the polarisation of the emission of the Milky Way at these wavelengths. This is a window of observation not previously explored, which provides complementary information to that obtained previously by space mission (Planck and WMAP) dedicated to the study of the cosmic microwave background radiation (CMB), the fossil radiation left behind by the Big Bang.

The optical fibre that keeps data safe even after being twisted or bent
Physicists have created an optical fibre that uses the maths concept of topology to remain robust, thereby guaranteeing the high-speed transfer of information. Optical fibres are the backbone of our modern information networks. From long-range communication over the internet to high-speed information transfer within data centres and stock exchanges, optical fibre remains critical in our globalised world.

Lucky find! How science behind epidemics helped Sussex physicists to develop state-of-the-art conductive paint
In new research published in Nature Communications , University of Sussex scientists demonstrate how a highly conductive paint coating that they have developed mimics the network spread of a virus through a process called 'explosive percolation' - a mathematical process which can also be applied to population growth, financial systems and computer networks, but which has not been seen before in materials systems.

How magnetic waves interact with Earth’s bubble
A new study involving UCL has uncovered how magnetic waves are transmitted past a standing shock wave, known as the bow shock, that forms ahead of Earth as a result of the solar wind hitting our magnetic bubble (magnetosphere). Shock waves occur in air when a plane travels faster than the speed of sound and also occur in plasma (a fourth state of matter that makes up 99% of the visible Universe) in space.

Mysteriously bright flash is a black hole jet pointing straight toward Earth, astronomers say
Astronomers have determined the source of an incredibly bright X-ray, optical and radio signal appearing from halfway across the Universe. The signal, named AT 2022cmc, was discovered earlier this year by the Zwicky Transient Facility in California. Findings published today in Nature Astronomy, suggest that it is likely from a jet of matter, streaking out from a supermassive black hole at close to the speed of light.

Non-detection of key signal allows astronomers to determine what the first galaxies were - and weren’t - like
Researchers have been able to make some key determinations about the first galaxies to exist, in one of the first astrophysical studies of the period in the early Universe when the first stars and galaxies formed, known as the cosmic dawn.

Shock waves trigger black holes’ powerful jets
Powerful jets of material released by black holes are accelerated far into space by shock waves within the jets, an international collaboration involving UCL researchers has found. The study, published in Nature , helps to solve a decades-old mystery about how these jets are produced. The research team was able to rule out alternative causes of the jets - such as magnetic reconnection - and, out of a number of theoretical models of how the particles in the jets are accelerated, showed that just one model was correct.
