'Ironing' out the differences: Understanding superconductivity in ultrathin FeSe

Scientists at Tokyo Institute of Technology (Tokyo Tech) elucidate the underlying cause behind the different critical transition temperatures reported for ultrathin iron selenide (FeSe) superconductors. Their results clarify why the interface between the first FeSe layer and its substrate play an essential role in superconductivity, giving new insights into a long-standing puzzle in this field.

Order out of disorder in ice

The glass structure of a material is often believed to mimic its corresponding liquid. Polyamorphism between ices has been used as a guide to elucidate the properties of liquid water. But how many forms of amorphous ices are there? Do we understand how metastable high-pressure crystalline ice evolves towards the thermally stable low-density form?

Imaging magnetic instabilities using laser accelerated protons

The magnetic structures resulting from a plasma instability predicted by the physicist Erich Weibel about 50 years ago have been evidenced at surprisingly large scales in a laser-driven plasma in the prestigious journal Nature Physics. This instability is also expected to operate in astrophysical settings where it is held responsible for the acceleration of cosmic rays and the emission of gamma photons in the famous "gamma-ray bursts."

New model helps to describe defects and errors in quantum computers

A summer internship in Bilbao, Spain, has led to a paper in the journal Physical Review Letters for Jack Mayo, a Master's student at the University of Groningen, the Netherlands. He has helped to create a universal model that can predict the number distribution of topological defects in non-equilibrium systems. The results can be applied to quantum computing and to studies into the origin of structure in the early Universe.

Plug-and-play lens simplifies adaptive optics for microscopy

Researchers have developed a new plug-and-play device that can add adaptive optics correction to commercial optical microscopes. Adaptive optics can greatly improve the quality of images acquired deep into biological samples, but has, until now, been extremely complex to implement.

Improved understanding of the behavior of electrons in plasmas

Plasmas are strongly associated with thermonuclear reactions inside stars such as the sun, but in modern society, plasmas have found application in lithographic processes and decontamination techniques. High-temperature plasmas, like those in the sun, can be quite energy-inefficient for chemical applications and degrade materials in processes. One way to address such issues is to manipulate plasmas in a low-temperature environment. Ph.D. candidate Bart Platier has developed a new plasma-based production technique using low-temperature and atmospheric pressure plasmas for illumination diffusers, which are used in lighting technologies to improve the distribution of light. Platier defends his Ph.D. thesis on June 26th.

Astronomy and Space news

Neptune-sized planet discovered orbiting young, nearby star

For more than a decade, astronomers have searched for planets orbiting AU Microscopii, a nearby star still surrounded by a disk of debris left over from its formation. Now scientists using data from NASA's Transiting Exoplanet Survey Satellite (TESS) and retired Spitzer Space Telescope report the discovery of a planet about as large as Neptune that circles the young star in just over a week.

New remnant radio galaxy detected

Using the Giant Metrewave Radio Telescope (GMRT), astronomers from South Africa and India have discovered a new remnant radio galaxy. The newly detected object, designated J1615+5452 has a size exceeding 300,000 light years and showcases a diffuse amorphous radio emission. The finding is detailed in a paper published June 17 on

Rogue's gallery of dusty star systems reveals exoplanet nurseries

Astronomers this month released the largest collection of sharp, detailed images of debris disks around young stars, showcasing the great variety of shapes and sizes of stellar systems during their prime planet-forming years. Surprisingly, nearly all showed evidence of planets.

Beneath the surface of our galaxy's water worlds

Out beyond our solar system, visible only as the smallest dot in space with even the most powerful telescopes, other worlds exist. Many of these worlds, astronomers have discovered, may be much larger than Earth and completely covered in water—basically ocean planets with no protruding land masses. What kind of life could develop on such a world? Could a habitat like this even support life?

Physicist discusses eRosita mission

It may well mark a revolution in X-ray astronomy: The eRosita space telescope, which was launched last July, has completed its first complete survey of the sky. Over a million objects are visible on the map it has produced. Astronomers are excited about the results from the observatory. It was developed under the leadership of the Max Planck Institute for Extraterrestrial Physics and is intended to survey the entire sky with a previously unattained spectral and spatial resolution. We spoke with Peter Predehl, the scientific Director of eRosita, about the mission.

ESA listens in on black hole mission

European and Russian specialists recently worked together to catch signals from an astrophysical observatory mission, now mapping X-ray sources in our galaxy and beyond, discovering previously unknown supermassive black holes.

Ocean in Jupiter's moon Europa 'could be habitable'

A new model from NASA scientists supports the theory that the interior ocean in Jupiter's moon Europa would be able to sustain life. In addition they have calculated that this water, believed to be an ocean under the surface ice shell, could have been formed by breakdown of water-containing minerals due to either tidal forces or radioactive decay. This work, which is not yet peer-reviewed, is presented for the first time at the virtual Goldschmidt conference, and may have implications for other moons in the Solar System.

Video: SMOS monitoring droughts

In orbit for more than a decade, ESA's Earth Explorer satellite SMOS has not only exceeded its planned lifespan, but also surpassed its original scientific goals. Built to demonstrate new technology in space and address gaps in our scientific understanding of how Earth works as a system, this remarkable mission is now also being used for a number of practical applications.

Technology news

A statistical model of cognitive status for natural language generation

In order for robots to be used a wide variety of settings, they need to be able to communicate seamlessly with humans. In recent years, researchers have thus been developing increasingly advanced computational models that could allow robots to process human language and formulate adequate responses.

Researchers find solar photovoltaics benefits outweigh costs

Over the past decade, the cost of solar photovoltaic (PV) arrays has fallen rapidly. But at the same time, the value of PV power has declined in areas that have installed significant PV generating capacity. Operators of utility-scale PV systems have seen electricity prices drop as more PV generators come online. Over the same time period, many coal-fired power plants were required to install emissions-control systems, resulting in declines in air pollution nationally and regionally. The result has been improved public health—but also a decrease in the potential health benefits from offsetting coal generation with PV generation.

Artificial skin heals wounds and makes robots sweat

Imagine a dressing that releases antibiotics on demand and absorbs excessive wound exudate at the same time. Researchers at Eindhoven University of Technology hope to achieve just that, by developing a smart coating that actively releases and absorbs multiple fluids, triggered by a radio signal. This material is not only beneficial for the health care industry, it is also very promising in the field of robotics or even virtual reality.

The first use case: A digital assembly assistant for contact-free cooperation of humans and machines. It is tested in cooperation with Elabo GmbH at the Center for Artificial Intelligence Talents (CAIT).
