New study reveals what brought down the powerful Assyrian empire

For 1,400 years, the ancient Assyrian empire dominated the Middle East ruling an area stretching from Turkey to Egypt and east to Iran through what is today Northern Saudi Arabia and Iraq. And then it all fell apart because of a megadrought caused by climate change.

The Assyrians were truly a superpower of the […]

JWST discovers a new extremely metal-poor dwarf galaxy

Using the James Webb Space Telescope (JWST), astronomers have discovered a new dwarf galaxy, which received designation CAPERS-39810. Further investigation of CAPERS-39810 revealed that it is an extremely metal-poor galaxy. The discovery was detailed in a paper published January 24 on the arXiv pre-print server.

Two huge hot blobs of rock influence Earth’s magnetic field, study reveals

Exploring Earth’s deep interior is a far bigger challenge than exploring the solar system. While we have traveled 25 billion km into space, the deepest we have ever gone below our feet is just over 12 km. Consequently, little is known about the conditions at the base of the mantle and the top of the […]

Ultra-thin metasurface can generate and direct quantum entanglement

Quantum technologies, devices and systems that process, store, detect, or transfer information leveraging quantum mechanical effects, have the potential to outperform classical technologies in a variety of tasks. An ongoing quest within quantum engineering is the realization of a so-called quantum internet: a network conceptually analogous to today’s internet, in which distant nodes are linked […]

Niobium’s superconducting switch cuts near-field radiative heat transfer 20-fold

When cooled to its superconducting state, niobium blocks the radiative flow of heat 20 times better than when in its metallic state, according to a study led by a University of Michigan Engineering team. The experiment marks the first use of superconductivity—a quantum property characterized by zero electrical resistance—to control thermal radiation at the nanoscale. […]

Using duality to construct and classify new quantum phases

A team of theoretical researchers has found duality can unveil non-invertible symmetry protected topological phases, which can lead to researchers understanding more about the properties of these phases, and uncover new quantum phases. Their study is published in Physical Review Letters.

Ultra-thin metasurface chip turns invisible infrared light into steerable visible beams

The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the development of advanced technologies. Researchers at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have taken a significant step forward with the development of a metasurface that can turn invisible infrared light […]

Angstrom-scale plasmonic gap boosts nonlinear light output by 2,000% per volt

Researchers at the Institute for Molecular Science (NINS, Japan) and SOKENDAI have demonstrated a more than 2000% voltage-induced enhancement of near-field nonlinear optical responses. To achieve this giant modulation, they focused on an angstrom-scale gap formed between a metallic tip and substrate in a scanning tunneling microscope (STM), which can strongly confine and enhance light […]

Scientists genetically link orangutans to giant ape thought to be Bigfoot

Bigfoot may or may not be real, but there is a living relative of the giant ape thought to be Bigfoot already living among us known as the orangutan, according to scientists who studied the ape’s genetic code.

There have been countless Bigfoot sightings for hundreds of years, and the […]

Real-time single-event position detection using high-radiation-tolerance GaN

Silicon semiconductors are widely used as particle detectors; however, their long-term operation is constrained by performance degradation in high-radiation environments. Researchers at University of Tsukuba have demonstrated real-time, two-dimensional position detection of individual charged particles using a gallium nitride (GaN) semiconductor with superior radiation tolerance.

Machine learning accelerates plasma mirror design for high-power lasers

Plasma mirrors capable of withstanding the intensity of powerful lasers are being designed through an emerging machine learning framework. Researchers in Physics and Computer Science at the University of Strathclyde have pooled their knowledge of lasers and artificial intelligence to produce a technology that can dramatically reduce the time it takes to design advanced optical […]

AI streamlines deluge of data from particle collisions

Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have developed a novel artificial intelligence (AI)-based method to dramatically tame the flood of data generated by particle detectors at modern accelerators. The new custom-built algorithm uses a neural network to intelligently compress collision data, adapting automatically to the density or “sparsity” of the […]
