Less is more for Maxwell's Demon in quantum heat engines

Over 150 years after the famous Scottish scientist James Clerk Maxwell first introduced the idea, the concept of Maxwell's demon continues to perplex physicists and information scientists. The demon he dreamed up in a thought experiment, which could sort fast and slow particles into separate sides of a container, seemed to violate the second law of thermodynamics. By taking into account the demon's memory, physicists were able to bring the demon in line with the laws of statistical mechanics for classical systems, but the situation grew contentious once again when quantum heat engines were proposed, as thermodynamics physicists and information theorists wrangled over viable explanations. Recent results from physical modeling may bring the different arguments together.

Unstable rock pillars near reservoirs can produce dangerous water waves

In many coastal zones and gorges, unstable cliffs often fail when the foundation rock beneath them is crushed. Large water waves can be created, threatening human safety.

How can we stop the spread of false rumors about COVID-19? Better math

Think of all the false rumors that went viral about COVID-19—it got so bad, the World Health Organization called it an "infodemic." Whether it is in hoaxes or a viral conspiracy theory, information travels fast these days. Just how fast and far information moves depends on who shares it, and where, from discussions on social media to conversations with fellow commuters on your way to work.

Scientists shed light on mystery of dark matter

Scientists have identified a sub-atomic particle that could have formed the "dark matter" in the Universe during the Big Bang.

Hope for a new permanent magnet that's cheap and sustainable

Scientists have made a breakthrough in the search for a new, sustainable permanent magnet.

Manipulating atoms to make better superconductors

Scientists have been interested in superconductors—materials that transmit electricity without losing energy—for a long time because of their potential for advancing sustainable energy production. However, major advances have been limited because most materials that conduct electricity have to be very cold, anywhere from -425 to -171 degrees Fahrenheit, before they become superconductors.

Scientists created an 'impossible' superconducting compound

Scientists have created new superconducting compounds of hydrogen and praseodymium, a rare-earth metal, one substance being quite a surprise from the perspective of classical chemistry. The study helped find the optimal metals for room-temperature superconductors. The results were published in Science Advances.

Virtualized metamaterial opens door for acoustics application and beyond

Playing back recorded audio from digital storage allows us to enjoy music without the physical presence of a musical instrument to generate resonating sound. In a seemingly unrelated area called metamaterials, scientists design different physical structures also resonating with sound or light, to achieve many intriguing phenomena such as negative refraction and invisibility.

Biologically inspired ultrathin arrayed camera for high-contrast and high-resolution imaging

Vision systems in nature provide intriguing optical design inspiration for ultracompact imaging systems. Scientists in South Korea have now demonstrated a fully packaged ultrathin insect-eye camera, which offers high contrast and super-resolution imaging by using new optical materials and techniques. This ultrathin arrayed camera could have practical use in mobile devices, advanced surveillance vehicles, and endoscopes without technical reservation.

How a new quantum approach can develop faster algorithms to deduce complex networks

Our world has no dearth of complex networks—from cellular networks in biology to intricate web networks in technology. These networks also form the basis of various applications in virtually all fields of science, and to analyze and manipulate these networks, specific "search" algorithms are required. But, conventional search algorithms are slow and, when dealing with large networks, require a long computational time. Recently, search algorithms based on the principles of quantum mechanics have been found to vastly outperform classical approaches.

Scientists create the first diamond X-ray micro lens

After fourth-generation synchrotrons were invented (these are particle accelerators, which are, in fact, giant research facilities), there was an urgent need for a fundamentally new optics that could withstand high temperatures and radiation loads created by a powerful X-ray stream.

Astronomy & Space news

New eclipsing binary millisecond pulsar discovered by FAST

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have discovered a new eclipsing binary millisecond pulsar in the globular cluster NGC 6341 (or M92). The newly found object received designation PSR J1717+4308A or M92A. The finding is detailed in a paper published February 24 on

Milky Way's warp caused by galactic collision, Gaia suggests

Astronomers have pondered for years why our galaxy, the Milky Way, is warped. Data from ESA's star-mapping satellite Gaia suggest the distortion might be caused by an ongoing collision with another, smaller, galaxy, which sends ripples through the galactic disc like a rock thrown into water.

Shedding new light on black hole ejections

Academics from the University of Cape Town (UCT) are part of a research group led by the University of Oxford's Department of Physics that has observed a black hole ejecting material at close to the speed of light out to some of the largest angular distances (separations) ever seen. These observations have allowed a deeper understanding of how black holes feed into their environment.

Globular cluster billowing in the galactic wind

The galactic magnetic field plays an important role in the evolution of the galaxy, but its small-scale behaviour is still poorly known. It is also unknown whether it permeates the halo of the galaxy or not. By using observations of pulsars in the halo globular cluster 47 Tuc, an international research team led by Federico Abbate from the Max Planck Institute for Radio Astronomy in Bonn, Germany who started this work at University of Milano Bicocca and INAF-Astronomical Observatory of Cagliari, could probe the galactic magnetic field at scales of a few light years for the first time. They discovered an unexpected strong magnetic field in the direction of the cluster. This magnetic field points perpendicularly to the galactic disk and could be explained by an interaction with the galactic wind. This is a magnetized outflow that extends from the galactic disk into the surrounding halo and its existence has never been proven before.

Astronomers have succeeded in recording sunlight shining through the Earth's atmosphere in a manner similar to the study of distant exoplanets. During the extraordinary occasion of a lunar eclipse, the Large Binocular Telescope observed the light that was filtered by the Earth's atmosphere and reflected by the moon in unique detail. In addition to oxygen and water, atomic spectral lines of sodium, calcium and potassium were detected in our atmosphere in this way first time.

Dark web study reveals how new offenders get involved in online pedophile communities

The "dark web"—a collection of heavily encrypted websites, forums and social networks—notoriously provides spaces for illegal activities.

New lithium batteries from used cell phones

Lithium-ion batteries are used around the world, and though over the last few years they have had some competition, such as sodium and magnesium, they continue to be indispensable due to their high density and capacity. The issue is this: this metal has major availability and concentration problems. Almost 85% of its reserves are located in what is known as the Lithium Triangle, a geographical area found on the borders of Argentina, Bolivia and Chile. In addition, it seems that demand will rocket over the next few decades because of the implementation of electric vehicles. Each car equals about 7,000 cell phone batteries, so reusing their different components has become an issue of utmost importance.
