New 'whirling' state of matter discovered in an element of the periodic table

The strongest permanent magnets today contain a mix of the elements neodymium and iron. However, neodymium on its own does not behave like any known magnet, confounding researchers for more than a half-century. Physicists at Radboud University and Uppsala University have shown that neodymium behaves like a self-induced spin glass, meaning that it is composed of a rippled sea of many tiny whirling magnets circulating at different speeds and constantly evolving over time. Understanding this new type of magnetic behaviour refines our understanding of elements on the periodic table, and could eventually pave the way for new materials for artificial intelligence. The results will be published on 29th of May, in Science.

Topology sheds new light on synchronization in higher-order networks

Research led by Queen Mary University of London, proposes a novel 'higher-order' Kuramoto model that combines topology with dynamical systems and characterises synchronization in higher-order networks for the first time.

Fresh antimatter study will bolster future indirect dark matter searches

The ALICE collaboration has presented new results on the production rates of antideuterons based on data collected at the highest collision energy delivered so far at the Large Hadron Collider. The antideuteron is composed of an antiproton and an antineutron. The new measurements are important because the presence of antideuterons in space is a promising indirect signature of dark matter candidates. The results mark a step forward in the search for dark matter.

New technique offers higher resolution molecular imaging and analysis

A Northwestern University research team has developed a new method to conduct spectroscopic nanoscopy, an approach that could help researchers understand more complicated biomolecular interactions and characterize cells and diseases at the single-molecule level.

A single proton can make a world of difference

Scientists from the RIKEN Nishina Center for Accelerator-Based Science and collaborators have shown that knocking out a single proton from a fluorine nucleus—transforming it into a neutron-rich isotope of oxygen—can have a major effect on the state of the nucleus. This work could help to explain a phenomenon known as the oxygen neutron dripline anomaly.

Configurable circuit technology poised to expand silicon photonic applications

Researchers have developed a new way to build power efficient and programmable integrated switching units on a silicon photonics chip. The new technology is poised to reduce production costs by allowing a generic optical circuit to be fabricated in bulk and then later programmed for specific applications such as communications systems, LIDAR circuits or computing applications.

'Bottom-heavy squirmers' adopt characteristic group behaviours

From starling aberrations to self-turbulent fluids, 'active systems' encompass a wide family of phenomena in which individual objects propel themselves forward, allowing them to display intriguing collective behaviors. On microscopic scales, they are found in groups of living organisms which move around by squirming, and are aligned with Earth's gravitational fields due to their bottom-heavy mass distributions. Through research published in EPJ E, Felix Rühle and Holger Stark at the Technical University of Berlin find that depending on their properties, these objects collectively spend most of their time in one of two states, between which some intriguing behaviors can emerge.

Convenient location of a near-threshold proton-emitting resonance in boron-11

Polish scientists working in Poland, France and the USA explained the mysterious β-delayed proton decay of the neutron halo ground state of 11Be. Studies within the SMEC model suggest the existence of collective resonance, carrying many characteristics of a nearby proton-decay channel, which explains this puzzling decay. It was argued that the appearance of such near-threshold resonant states is a generic phenomenon in any open quantum system, in which bound and unbound states strongly mix.

Astronomy and Space news

Extremely intense radio burst detected from magnetar SGR 1935+2154

Using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope, astronomers have detected a bright, millisecond-duration radio burst from a galactic magnetar known as SGR 1935+2154. The discovery of such an extremely intense event, reported in a paper published May 20, could be important for improving the understanding of the origin of fast radio bursts (FRBs).

In planet formation, it's location, location, location

Astronomers using NASA's Hubble Space Telescope are finding that planets have a tough time forming in the rough-and-tumble central region of the massive, crowded star cluster Westerlund 2. Located 20,000 light-years away, Westerlund 2 is a unique laboratory to study stellar evolutionary processes because it's relatively nearby, quite young, and contains a large stellar population.

Half the matter in the universe was missing—we found it hiding in the cosmos

In the late 1990s, cosmologists made a prediction about how much ordinary matter there should be in the universe. About 5%, they estimated, should be regular stuff with the rest a mixture of dark matter and dark energy. But when cosmologists counted up everything they could see or measure at the time, they came up short. By a lot.

ESPRESSO confirms the presence of an Earth-sized planet around the nearest star (Update)

The existence of a planet the size of Earth around the closest star to the Sun, Proxima Centauri, has been confirmed by an international team of scientists including researchers from the University of Geneva (UNIGE). The results, published in Astronomy & Astrophysics, reveal that the planet in question, Proxima b, has a mass of 1.17 Earth masses and is located in the habitable zone of its star, which it orbits in 11.2 days.

Hydropower plants to support solar and wind energy in West Africa

Hydropower plants can support solar and wind power, rather unpredictable by nature, in a climate-friendly manner. A new study in the scientific journal Nature Sustainability has now mapped the potential for such "solar-wind-water" strategies for West Africa: an important region where the power sector is still under development, and where generation capacity and power grids will be greatly expanded in the coming years. "Countries in West Africa therefore now have the opportunity to plan this expansion according to strategies that rely on modern, climate-friendly energy generation," says Sebastian Sterl, energy and climate scientist at Vrije Universiteit Brussel and KU Leuven and lead author of the study. "A completely different situation from Europe, where power supply has been dependent on polluting power plants for many decades—which many countries now want to rid themselves of."

Evidence suggests that the U.S. loses hundreds of billions to cybercrime, possibly as much as 1% to 4% of GDP annually

Cybercrime puts America's competitive edge and economic future at risk; however, there is some debate as to the extent that this activity is impacting economic activity. Many have questioned the validity of estimates of cybercrime losses, concluding that "they are so compromised and biased that no faith whatever can be placed in their findings" (Florencio and Herley 2016). NIST AMS 100-32 addresses a number of issues and challenges by using a large dataset and taking a number of approaches to increase accuracy and reliability.
