Answering the mystery of what atoms do when liquids and gases meet
Answering the mystery of what atoms do when liquids and gases meet
How atoms arrange themselves at the smallest scale was thought to follow a 'drum-skin' rule, but mathematicians have now found a simpler solution. Atomic arrangements in different materials can provide a lot of information about the properties of materials, and what the potential is for altering what they can be used for.

Nanoscale tweezers can perform single-molecule ’biopsies’ on individual cells
Using electrical impulses, the 'tweezers' can extract single DNA, proteins and organelles from living cells without destroying them. We are continuously expanding our knowledge on how cells function, but many unanswered questions remain. This is especially true for individual cells that are of the same type, such as brain, muscle or fat cells, but have very different compositions at the single-molecule level.

Marsquakes’ mission successfully lands on Red Planet
A mission to Mars which carries instruments co-designed by Oxford scientists, has successfully landed and will soon begin the first study of the heart of the planet. The NASA InSight mission landed shortly after 19:50 GMT on Monday, 26 November. InSight will study the inside of Mars to learn how planets, moons and meteorites with rocky surfaces, including the Earth and its Moon, formed.

Finding rules in the chaos that could help reveal secrets of the Big Bang
New research has revealed that non-equilibrium quantum systems do obey universal laws, a discovery that can bring us closer to revealing the secrets of the Big Bang. Researchers from the University of Nottingham joined teams at the Technical University of Vienna and the University Heidenberg to undertake It shows that when quantum particles whirl around they obey universal laws, meaning what is true for one quantum system is also true for others.

Auroras unlock the physics of energetic processes in space
A close study of auroras has revealed new ways of understanding the physics of explosive energy releases in space, according to new UCL-led research. Auroras are an incredible light show caused by electrically charged particles in near-Earth space spiralling down Earth's magnetic field and colliding with gases in the atmosphere, causing them to glow. They are also a tell-tale sign of physical processes in space, acting like TV screens by showing what happens millions of kilometres away from Earth where our planet's magnetic field stretches into a long tail facing away from the Sun.

Comet tails: charged dust blowing in the solar wind
Comet tails: charged dust blowing in the solar wind
How a comet's dust tail forms bands stretching millions of kilometres across the sky has been observed for the first time by UCL scientists. The study, published today in Icarus, reveals the charged nature of the dust particles and the important role of the Sun in forming the characteristic patterns. An international team led by researchers from UCL Mullard Space Science Laboratory (UCL MSSL) successfully mapped the movement of dust particles in Comet C/2006 P1 McNaught, one of the brightest comets visible from Earth in the past 50 years.

New wireless device can aid recovery of breast cancer patients
A new sensing device can provide early warning of potential failure of breast reconstruction surgery, making it easier to take effective action. An international team led by Imperial College London and funded by the Engineering and Physical Sciences Research Council (EPSRC) have developed the wireless ‘bio-patch' as part of the Smart Sensing for Surgery project.

New efficiency record set for perovskite LEDs
Researchers have set a new efficiency record for LEDs based on perovskite semiconductors, rivalling that of the best organic LEDs (OLEDs). Compared to OLEDs, which are widely used in high-end consumer electronics, the perovskite-based LEDs, developed by researchers at the University of Cambridge, can be made at much lower costs, and can be tuned to emit light across the visible and near-infrared spectra with high colour purity.

First high-temperature single-molecule magnet
First high-temperature single-molecule magnet
Scientists discover the first high-temperature single-molecule magnet. This could be relevant for molecule-based magnetic information storage materials. The research group reports a new single-molecule magnet (SMM) - a type of material that retains magnetic information up to a characteristic blocking temperature.

Graphene may exceed bandwidth demands of future telecommunications
Graphene may exceed bandwidth demands of future telecommunications
Researchers from the Cambridge Graphene Centre, together with industrial and academic collaborators within the European Graphene Flagship project, showed that integrated graphene-based photonic devices offer a solution for the next generation of optical communications. The researchers have demonstrated how properties of graphene - a two-dimensional form of carbon - enable ultra-wide bandwidth communications and low power consumption to radically change the way data is transmitted across the optical communications systems.

Pentacene patterns prove crucial for solar power
Solar panels could be improved by arranging their molecules in a certain pattern, according to new research led by Imperial and UCL. Renewable solar power can be harnessed using solar cells, which are made of materials called semiconductors. In a solar cell, electrons are generated when photons, or packets of light, are absorbed by semiconductors and released as high energy electrons.

World’s largest neutrino detector brings scientists closer to understanding the universe
International scientists are one step closer to answering the most fundamental question of our existence, ‘why are we here'', as part of a global collaboration involving UCL researchers. The Deep Underground Neutrino Experiment (DUNE) is led by scientists at CERN, Switzerland and Fermilab, USA, and is dedicated to unlocking the mysteries of neutrinos, the most abundant and most mysterious matter particles in the universe.

Latest insights into Saturn's weird magnetic field only make things weirder
Latest insights into Saturn’s weird magnetic field only make things weirder
Some of the last data from the Cassini mission reveals more structure in Saturn's magnetic field, but still no answer as to how it formed. NASA's Cassini mission - with Imperial kit on board - took a series of daring dives between the planet and its inmost ring in September 2017 before burning up in the planet's atmosphere.

Just seven photons can act like billions
A system made of just a handful of particles acts just like larger systems, allowing scientists to study quantum behaviour more easily. Most substances physicists study are made up of huge numbers of particles - so large that there is essentially no difference between the behavioural properties of a drop or a swimming pool's worth of pure water.

Long-sought decay of Higgs boson observed
UCL particle physicists are celebrating that the ATLAS Collaboration at CERN's Large Hadron Collider (LHC) has - at long last - observed the Higgs boson decaying into a pair of bottom (b) quarks. The elusive interaction is predicted to make up almost 60% of the Higgs boson decays. "Finding the Higgs in its favoured decay channel was one of the key missing items in our knowledge of the Higgs boson.
