"Qutrit": Complex quantum teleportation achieved for the first time
Austrian and Chinese scientists have succeeded in teleporting three-dimensional quantum states for the first time. High-dimensional teleportation could play an important role in future quantum computers. Researchers from the Austrian Academy of Sciences and the University of Vienna have experimentally demonstrated what was previously only a theoretical possibility.

Atomically thin heat shield protects electronics
Atomically thin materials developed by Stanford researchers could create heat-shields for cell phones or laptops that would protect people and temperature-sensitive components and make future electronic gadgets even more compact. Excess heat given off by smartphones, laptops and other electronic devices can be annoying, but beyond that it contributes to malfunctions and, in extreme cases, can even cause lithium batteries to explode.

How do atoms vibrate in graphene nanostructures?
Innovative new electron spectroscopy technique pushes the limits of Nanospectroscopy for materials design In order to understand advanced materials like graphene nanostructures and optimize them for devices in nano-, optoand quantum-technology it is crucial to understand how phonons - the vibration of atoms in solids - influence the materials' properties.

Scientists can now control thermal profiles at the nanoscale
At human scale, controlling temperature is a straightforward concept. Turtles sun themselves to keep warm. To cool a pie fresh from the oven, place it on a room-temperature countertop. At the nanoscale - at distances less than 1/100th the width of the thinnest human hair - controlling temperature is much more difficult.

A light-trapping, color-converting crystal
A recipe for creating a microscopic crystal structure that can hold two wavelengths of light at once is a step toward faster telecommunications and quantum computers. Five years ago, Stanford postdoctoral scholar Momchil Minkov encountered a puzzle that he was impatient to solve. At the heart of his field of nonlinear optics are devices that change light from one color to another - a process important for many technologies within telecommunications, computing and laser-based equipment and science.

Global team of scientists finish assembling next-generation dark matter detector
The key component of the LUX-ZEPLIN experiment is ready to be sealed and lowered nearly 1.5 km underground, where it will search for dark matter. Dark matter is a mysterious form of matter thought to make up around 85% of the mass of the universe. However, because it is predicted to interact only very weakly with ordinary matter, it has so far not been detected.

Super-resolution microscopy sheds light on dementia
University of Queensland researchers have used super-resolution microscopy to observe key molecules at work inside living brain cells, further unravelling the puzzle of memory formation and the elusive causes of dementia. UQ Queensland Brain Institute 's Clem Jones Centre for Ageing and Dementia Research Professors Frédéric Meunier and Jürgen Götz found a protein, Tau, involved in Alzheimer's disease affects the organisation of the signalling protein Fyn, which plays a critical role in memory formation.

Is your Supercomputer Stumped? There May Be a Quantum Solution
S ome math problems are so complicated that they can bog down even the world's most powerful supercomputers. But a wild new frontier in computing that applies the rules of the quantum realm offers a different approach. A new study led by a physicist at Lawrence Berkeley National Laboratory (Berkeley Lab), published in the journal Scientific Reports, details how a quantum computing technique called "quantum annealing" can be used to solve problems relevant to fundamental questions in nuclear physics about the subatomic building blocks of all matter.

Ultradense arrays of magnetic quanta in high-temperature superconductors The properties of high-temperature superconductors can be tailored by the introduction of artificial defects.

New Recipes for Taking Salt Out of Seawater
Promising design rules for cost-effective desalination rely on just a few ingredients: ionic liquids plus low-cost geothermal or solar heat, or waste heat from machines A s populations boom and chronic droughts persist, coastal cities like Carlsbad in Southern California have increasingly turned to ocean desalination to supplement a dwindling fresh water supply.

Moving Forward on Desalination
A Q&A with scientist Jeff Urban, who explains forward osmosis and how Berkeley Lab is pushing the frontiers of this emerging technology As global populations grow and water scarcity becomes an increasingly pressing issue, the number of desalination plants is growing. There are now more than 20,000 worldwide, and more than 300 million people around the world rely on desalination for some or all of their daily water needs, according to the International Desalination Association.

Quantum computers to clarify the connection between the quantum and classical worlds
A new algorithm will allow quantum computers to investigate how the classical world we experience emerges from the quantum world The quantum-to-classical transition occurs when you add more and more particles to a quantum system, such that the weird quantum effects go away and the system starts to behave more classically.

Making biominerals: nature’s recipe is old, evolved more than once
In recent years, scientists have teased out many of the secrets of biomineralization, the process by which sea urchins grow spines, mollusks build their shells and corals make their skeletons, not to mention how mammals and other animals make bones and teeth. The materials that animals make from scratch to build protective shells, razor sharp teeth, load-bearing bones and needlelike spines are some of the hardest and most durable substances known.

Lab-based dark energy experiment narrows search options for elusive force
An experiment to test a popular theory of dark energy has found no evidence of new forces, placing strong constraints on related theories. Dark energy is the name given to an unknown force that is causing the universe to expand at an accelerating rate. It is very exciting to be able to discover something about the evolution of the universe using a table-top experiment in a London basement.

Hydrogen induces high-temperature superconductivity in a monolayer material
UAntwerp researchers from the CMT group, Dr Jonas Bekaert and Prof Milorad Milosevic, in collaboration with Swedish researchers have predicted that a atomically thin layer of hydrogen will boost the critical temperature of a thin superconductor to above a hundred kelvin. Hydrogen-rich bulk superconducting materials have recently exhibited record-breaking critical temperatures, nearing the ambient temperature and thereby promising a major technological impact on the society.

Physicists Develop "Time Machine" for Materials Science
Physics experiments are often time-consuming and expensive. Sometimes scientists do not realize until the very end that they have been using the wrong calibration for measurements the whole time. What if there were a way to go back in time to the start of the experiment and re-examine the data? Researchers at Martin Luther University Halle-Wittenberg (MLU), Freie Universität Berlin, and the Technical University of Munich (TUM) hope to create a machine that would make that possible.

Bending the rules: A revolutionary new way for metals to be malleable
For nearly 100 years, scientists thought they understood everything there was to know about how metals bend. They were wrong. Materials science and engineering researchers at the University of Wisconsin-Madison have demonstrated that the rules of metal-bending aren't so hard and fast after all. They described their findings Aug.

Scientists uncover deep-rooted plumbing system beneath ocean volcanoes
Cardiff University scientists have revealed the true extent of the internal ‘plumbing system' that drives volcanic activity around the world. An examination of pockets of magma contained within crystals has revealed that the large chambers of molten rock which feed volcanoes can extend to over 16 km beneath the Earth's surface.

Artificial tongue could have whisky counterfeiting licked
An artificial 'tongue' which can taste subtle differences between drams of whisky could help cut down on the trade in counterfeit alcohol, scientists say. In a new paper published today in the Royal Society of Chemistry's journal Nanoscale, Scottish engineers describe how they built the tiny taster, which exploits the optical properties of gold and aluminium to test the tipples.
