Inexpensive material compresses light, paving the way for photonic microcircuits in the terahertz range

A two-dimensional lamellar crystal composed of atomically thin layers of lead iodide (PbI2) could be used to manufacture a new generation of circuits that use light and mechanical vibrations (rather than electrons) to transmit information in the terahertz frequency range.

Elastic rules may explain why nematic crystals look ordered and disordered at once

Electronic nematicity is a phase of some crystalline solids in which electrons’ collective properties, such as charge or spin densities, organize themselves into ordered patterns, lowering the crystal’s rotational symmetry. This phase is found across a wide range of diverse materials, making nematicity crucial to understanding emergent solid-state phenomena, such as unconventional superconductivity and magnetism.

Video: Calif. law enforcement officers trap street takeover bikers on Bay Bridge, seizing 80 vehicles

More than 100 Oakland, San Francisco and CHP officers participated in the operation that trapped riders in between agencies on the bridge, leading to multiple arrests

Astronomers map lifetime of over 100,000 molecular clouds across 66 galaxies

An international team of astronomers has analyzed the data from the James Webb Space Telescope (JWST) and Atacama Large Millimeter/submillimeter Array (ALMA) to investigate giant molecular clouds in nearby galaxies. The new study, presented April 27 on the arXiv preprint server, unveils crucial information regarding the lifetime of more than 100,000 such clouds across 66 galaxies.

JWST pins down the origins of a planetary odd couple

Across the Milky Way galaxy, a planetary odd couple is circling a star some 190 light years from Earth. A normally “lonely” hot Jupiter is sharing space with a mini-Neptune, in a rare and unlikely pairing that’s had astronomers puzzled since the system’s discovery in 2020.

Blue Origin moon lander completes testing at NASA vacuum chamber

Also known as Endurance, MK1 is an uncrewed cargo lander. It’s a commercial demonstration mission to advance Human Landing System capabilities in support of NASA’s Artemis program. The tests in Chamber A represent a public-private partnership model, with Blue Origin conducting work through a reimbursable Space Act Agreement.

Magnetic fields can ‘revive’ superconductivity in nickelates, research reveals

A research team led by Professor Denver Li Danfeng, Associate Dean (Research and Postgraduate Education) of the College of Science and Associate Professor in the Department of Physics at City University of Hong Kong (CityUHK), has achieved a significant advance in superconducting materials.

Understanding how lasers can rapidly magnetize fusion plasmas

The mechanism that can cause a rapidly expanding plasma—the superhot state of matter harnessed in fusion energy systems—to spontaneously generate its own magnetic fields was identified through a new set of simulations. This improves our understanding of naturally occurring plasmas in our universe and advances the development of fusion systems based on an approach called direct-drive inertial fusion.

BWC: Texas civilian officer shot in face with pellet gun while responding to day-old burglary report

The Fort Worth Civilian Response Unit officer, who was not armed with a gun, was struck by pellets on his face and eye as he ushered a bystander to safety

Secret Service agents shoot man who opened fire at them near Washington Monument

The unidentified man attempted to flee when uniformed officers with the Secret Service approached him; he then fired at the officers, who returned fire

We might have massively underestimated Io’s thermal output

Io is a world of extremes. It is by far the most volcanically active world in our solar system. Being continually squeezed in the never-ending tug-of-war between Jupiter and its larger satellites will do that to a moon. As a result, Io has over 400 “paterae”—volcanic depressions that spew lava up onto its surface. And, according to a new paper available in pre-print on arXiv and utilizing data from Juno’s Jupiter InfraRed Auroral Mapper (JIRAM) tool, we have been massively underestimating the power output of those paterae for decades.

N.M. city to pay $6.5M in fatal shooting of man during mental health call

The 2022 fatal shooting of a man, who was well-known to police, prompted the Albuquerque PD to change use-of-force policies

Optically dark gamma-ray burst reveals an unusually wide jet

Using various telescopes, an international team of astronomers has performed multi-wavelength observations of a recently identified gamma-ray burst source designated GRB 250416C. Results of the observational campaign, published April 23 on the v pre-print server, could help us better understand the nature of GRB 250416C and gamma-ray bursts in general.

Symmetry says these crystal vibrations can never mix, but an exotic quantum phase rewrites the rules

Symmetry is one of the most fundamental principles in nature. It describes the rules that make an object look unchanged after a rotation, reflection, or other transformations. In materials, symmetry governs how atoms and electrons are arranged, and how they move together. Crucially, symmetry can even prevent certain collective atomic motions (vibrations) from interacting at all: some are simply forbidden to talk to each other. But what if those symmetry restrictions are not as rigid as they seem?

Mathematical framework solves asteroid route planning exactly for first time

A new publication from Bielefeld University sets a benchmark in optimization research. Together with an international team, Professor Michael Römer from the Faculty of Business Administration and Economics has developed a mathematical framework that solves a complex problem from space logistics exactly for the first time: the optimal planning of a route to visit several asteroids under conditions that are as close to reality as possible. The study is published in the INFORMS Journal on Computing.
