A connection between quantum correlations and spacetime geometry
A connection between quantum correlations and spacetime geometry
Researchers of the Academy explore the consequences of locality for measurements distributed in spacetime. Their article has now been published in the Nature journal "Quantum Information". Locality is a fundamental principle behind all physical interactions. It says that each physical system can only interact with other systems in its immediate vicinity, so that interactions between two distant objects must be mediated by an intermediary.

New Semiconductor Technology for Future Data Communications
Researchers have developed world-leading Compound Semiconductor (CS) technology that can drive future high-speed data communications. A team from Cardiff University worked to innovate an ultrafast and highly sensitive ‘avalanche photodiode' (APD) that creates less electronic ‘noise' than its silicon rivals.

Chameleon Theory could change our thoughts on gravity
Chameleon Theory could change our thoughts on gravity
Einstein's theory of General Relativity is world famous - but it might not be the only way to explain how gravity works and how galaxies form. Physicists at Durham University created huge supercomputer simulations of the universe to test an alternative theory. Our researchers found that f(R)-gravity - a so-called Chameleon Theory - could also explain the formation of structures in the cosmos.

Simulating quantum systems with neural networks
Simulating quantum systems with neural networks
A new computational method, based on neural networks, can simulate open quantum systems with unprecedented versatility. The method was independently developed by physicists at EPFL, France, the UK, and the US, and is published in Physical Review Letters. Even on the scale of everyday life, nature is governed by the laws of quantum physics.

Molecular energy machine as a movie star
Molecular energy machine as a movie star
Researchers at the Paul Scherrer Institute PSI have used the Swiss Light Source SLS to record a molecular energy machine in action and thus to reveal how energy production at cell membranes works. For this purpose they developed a new investigative method that could make the analysis of cellular processes significantly more effective than before.

Scientists combine light and matter to make particles with new behaviors
Every type of atom in the universe has a unique fingerprint: It only absorbs or emits light at the particular energies that match the allowed orbits of its electrons. That fingerprint enables scientists to identify an atom wherever it is found. A hydrogen atom in outer space absorbs light at the same energies as one on Earth.

Activity of fuel cell catalysts doubled
Activity of fuel cell catalysts doubled
Fuel cells may well replace batteries as the power source for electric cars. They consume hydrogen, a gas which could be produced for example using surplus electricity from wind power plants. However, the platinum used in fuel cells is rare and extremely expensive, which has been a limiting factor in applications up to now.

Researchers cast neural nets to simulate molecular motion
Researchers cast neural nets to simulate molecular motion
Machine learning allows quantum mechanics to be efficiently applied to molecular simulations for drug development, detonation physics and more This means we can now model materials and molecular dynamics billions of times faster compared to conventional quantum methods, while retaining the same level of accuracy.

Generation and sampling of quantum states of light in a silicon chip
Scientists from the University of Bristol and the Technical University of Denmark have found a promising new way to build the next generation of quantum simulators combining light and silicon micro-chips. In the roadmap to develop quantum machines able to compete and overcome classical supercomputers in solving specific problems, the scientific community is facing two main technological challenges.

Mini 'magic' MRI scanner could diagnose knee injuries more accurately
Mini ’magic’ MRI scanner could diagnose knee injuries more accurately
Researchers at Imperial College London have developed a prototype mini MRI scanner that fits around a patient's leg. The team say the device - which uses so-called ‘magic angle' effect - could potentially help diagnose knee injuries more quickly, and more accurately. Knee injuries affect millions of people - and MRI scans are crucial to diagnosing the problem Dr Karyn Chappell Study author In a proof-of-concept study using animal knees, the results suggest the technology could be used to show all the structures of the knee.

Trying to conceive? It's an exercise in fertility
Trying to conceive? It’s an exercise in fertility
Exercise may improve a woman's chances of falling pregnant, a University of Queensland study has found. Dr Gabriela Mena , from UQ's School of Human Movement and Nutrition Sciences , analysed research on reproductive health and exercise from the last two decades. “When physical activity was compared with standard fertility treatments, such as IVF or ovulation induction, there was no difference in pregnancy rates and live births between women exercising and those undertaking fertility treatments,” Dr Mena said.

Researchers verify 70-year-old theory of turbulence in fluids
Pilots and air travellers know turbulence can be powerful, but science has struggled to fully explain the phenomenon. Now, a University of Queensland study has confirmed a 70-year-old theory and is expected to help address “huge problems” in global engineering and transport. Dr Tyler Neely from the ARC Centre of Excellence for Engineered Quantum Systems (EQUS) said enormous amounts of energy were used daily to transport all sorts of fluids through pipes all over the world.

Scientists Capture Atomic Motion in 4D for the First Time
Scientists Capture Atomic Motion in 4D for the First Time
Adapted from the original release published by UCLA.  Everyday transitions from one state of matter to another - such as freezing, melting, or evaporation - start with a process called "nucleation," in which tiny clusters of atoms or molecules (called "nuclei") begin to coalesce. Nucleation plays a critical role in circumstances as diverse as the formation of clouds and the onset of neurodegenerative disease.

Identifies Fukushima reactor material in environment
Through the analysis of specific fallout particles in the environment, a joint UK-Japan team of scientists has uncovered new insights into the sequence of events that led to the Fukushima nuclear accident in March 2011. The multi-organisation research, led by Dr Peter Martin and Professor Tom Scott from the University of Bristol's South West Nuclear Hub in collaboration with scientists from Diamond Light Source, the UK's national synchrotron facility, and the Japan Atomic Energy Agency (JAEA), has been published today .

Researchers harness AI to combat colon cancer
Engineers have shown that it is technically possible to use an AI system to guide a tiny robotic capsule inside the colon to take microultrasound images. Known as a ‘Sonopill', the device could spell the end for painful endoscopic examinations for patients, where a semi-rigid scope is passed into the bowel.

A crystal with a twist
UC Berkeley and Berkeley Lab researchers created a new crystal built of a spiraling stack of atomically thin germanium sulfide sheets. (UC Berkeley image by Yin Liu) With a simple twist of the fingers, one can create a beautiful spiral from a deck of cards. In the same way, scientists at the University of California, Berkeley, and Lawrence Berkeley National Laboratory (Berkeley Lab) have created new inorganic crystals made of stacks of atomically thin sheets that unexpectedly spiral like a nanoscale card deck.
