Giant impacts caused by interplanetary collisions
Giant impacts caused by interplanetary collisions
Astronomers have found fresh evidence for significant planetary diversity within a single exoplanet system, suggesting that giant high-speed collisions are partly responsible for planetary evolution. An international team of scientists led by Italy's National Institute for Astrophysics (INAF) and involving physicists from the University of Bristol spent three years observing the exoplanetary system Kepler-107 via the Telescopio Nazionale Galileo in La Palma.

Observing hydrogen's effects in metal
Observing hydrogen’s effects in metal
Microscopy technique could help researchers design safer reactor vessels or hydrogen storage tanks. Hydrogen, the second-tiniest of all atoms, can penetrate right into the crystal structure of a solid metal. That's good news for efforts to store hydrogen fuel safely within the metal itself, but it's bad news for structures such as the pressure vessels in nuclear plants, where hydrogen uptake eventually makes the vessel's metal walls more brittle, which can lead to failure.

Virtual lens improves X-ray microscopy
PSI researchers are first to transfer state-of-the-art microscopy method to X-ray imaging X-rays provide unique insights into the interior of materials, tissues, and cells. Researchers at the Paul Scherrer Institute PSI have developed a new method that makes X-ray images even better: The resolution is higher and allows more precise inferences about the properties of materials.

Faster than allowed by quantum computing?
Faster than allowed by quantum computing?
Researchers determine the performance of multi-dimensional bits Quantum computers are more powerful than classical computers since they work with coherent "quantum bits" instead of ordinary zeroes and ones. But what if the laws of nature were different from what we think today - could there be even more efficient "science fiction computers"- Researchers from the Austrian Academy of Sciences and the University of Vienna have now shown that this is not possible - as long as those machines satisfy the same construction principles as ordinary circuits and their quantum counterparts.

’Magnetic graphene’ switches between insulator and conductor
Researchers have found that certain ultra-thin magnetic materials can switch from insulator to conductor under high pressure, a phenomenon that could be used in the development of next-generation electronics and memory storage devices.

Unmanned vehicles to take quantum leap
Unmanned vehicles to take quantum leap
Quantum sensors being developed at the University of Queensland could revolutionise navigation and communications in unmanned and autonomous vehicles. UQ researchers are working with the Australian Defence Force (ADF), NASA , Orica Ltd and Brisbane's Skyborne Technologies to develop the next-generation sensors as part of a $6.6 million Australian initiative to develop quantum technologies for use in defence applications.

Knighthood for groundbreaking UofG astrophysicist
A pioneering University of Glasgow researcher who helped deliver the historic first detection of gravitational waves has received a knighthood in recognition of his contribution to physics and astronomy. James Hough, Research Professor in Natural Philosophy in the School of Physics and Astronomy, was made a Knight Bachelor of the British Empire by the Duke of Cambridgeduring a ceremony at Buckingham Palace today (Thursday 31 January).

Scientists ’hijack’ open-access quantum computer to tease out quantum secrets
The rules of quantum mechanics describe how atoms and molecules act very differently from the world around us. Scientists have made progress toward teasing out these rules-essential for finding ways to make new molecules and better technology-but some are so complex that they evade experimental verification.

Technique could boost resolution of tissue imaging as much as tenfold
Approach developed by MIT engineers surmounts longstanding problem of light scattering within biological tissue and other complex materials. Imaging deep inside biological tissue has long been a significant challenge. That is because light tends to be scattered by complex media such as biological tissue, bouncing around inside until it comes out again at a variety of different angles.

How does a quantum particle see the world?
Researchers at the University of Vienna study the relevance of quantum reference frames for the symmetries of the world According to one of the most fundamental principles in physics, an observer on a moving train uses the same laws to describe a ball on the platform as an observer standing on the platform - physical laws are independent on the choice of a reference frame.

Ingestible, expanding pill monitors the stomach for up to a month
Ingestible, expanding pill monitors the stomach for up to a month
Soft, squishy device could potentially track ulcers, cancers, and other GI conditions over the long term. The inflatable pill is embedded with a sensor that continuously tracks the stomach's temperature for up to 30 days. If the pill needs to be removed from the stomach, a patient can drink a solution of calcium that triggers the pill to quickly shrink to its original size and pass safely out of the body.

’Light tweezers’ can move, melt, and scatter mysterious biological ’icebergs’
For the first time, scientists have used light beams to manipulate lipid rafts in artificial cell membranes. Lipid rafts are domains, or areas, of protein and lipid (fats) which float freely in cell membranes - the protein and lipid layer that surrounds a cell. These structures, which float in the membranes like icebergs, play important but mysterious roles in cellular signalling that aren't yet fully explained.

Superconductors: Resistance is Futile
Superconductors: Resistance is Futile
New findings are changing the way we think about superconductivity. Experiments at TU Wien (Vienna) underline the special role of immobile charge carriers, acting as a 'glue', which makes superconductivity possible. Every standard cable, every wire, every electronic device has some electric resistance.

16 Elements: Berkeley Lab's Contributions to the Periodic Table
16 Elements: Berkeley Lab’s Contributions to the Periodic Table
In celebration of the 150th anniversary of the periodic table, a look at how far it's come and where it's headed. A century ago, the periodic table looked much different than it does today. It had empty spots for elements that had not yet been found, and ended at uranium (element 92), the heaviest known element until 1940.

New theory sends temperatures to new lows
Researchers have developed a new theory for recording the lowest temperatures ever measured, with the largest accuracy allowed by the laws of Nature. This line of research holds promise to revolutionise low-temperature physics and could find a plethora of applications in emerging quantum technologies.

How to Escape a Black Hole: Simulations Provide New Clues to What's Driving Powerful Plasma Jets
How to Escape a Black Hole: Simulations Provide New Clues to What’s Driving Powerful Plasma Jets
Black holes are known for their voracious appetites, binging on matter with such ferocity that not even light can escape once it's swallowed up. Less understood, though, is how black holes purge energy locked up in their rotation, jetting near-light-speed plasmas into space to opposite sides in one of the most powerful displays in the universe.

When Black Holes Collide
When Black Holes Collide
One of the most cataclysmic events to occur in the cosmos involves the collision of two black holes. Formed from the deathly collapse of massive stars, black holes are incredibly compact-a person standing near a stellar-mass black hole would feel gravity about a trillion times more strongly than they would on Earth.

Fine tuning for clean energy
An international collaboration between researchers in Spain and Scotland has resulted in a new approach to improve the catalysts needed to carry out the Hydrogen Evolution Reaction (HER). The reaction, in which water is transformed into hydrogen and oxygen, is a promising alternative to humanity's dependency on fossil fuels to satisfy energy requirements.
