A team of researchers, including NOIRLab astronomer André-Nicolas Chené, has found a highly unusual star that has the most powerful magnetic field ever found in a massive star — and that may become one of the most magnetic objects in the Universe: a variant of a neutron star known as a magnetar. This finding marks the discovery of a new type of astronomical object — a massive magnetic helium star — and sheds light on the origin of magnetars.

One of the less well-understood elementary particles, neutrinos rarely interact with normal matter, and instead travel invisibly through it at almost the speed of light.
Lynmarie K. Thompson has been elected President-elect of the Biophysical Society (BPS). She will assume the office of President-elect at the 2024 Annual Meeting in Philadelphia, Pennsylvania and begin her term as President during the 2025 Annual Meeting in Los Angeles, California. Thompson is a Professor of Chemistry at the University of Massachusetts Amherst (UMass).
Due to the poor chemical stability of the perovskite materials in the polar solvent, the most commonly used photolithography and etching techniques for patterning the single crystal arrays are highly incompatible with perovskite materials. To solve this problem, scientists in China invented a one-step space confinement and antisolvent-assisted crystallization (SC-ASC) method that enables the controlled fabrication of high-quality single crystal arrays on various substrates.
Metal-halide perovskite light-emitting diodes (PeLEDs) feature comprehensive advantages of wide color gamut, high luminescence efficiency and low-cost synthesis. PeLEDs are thus considered the promising photonic source for next-generation display applications. In this review, scientists from Nankai University discuss the key technical bottlenecks in PeLEDs for commercial display applications. These include large-area PeLEDs preparation, PeLEDs' patterning strategies, and flexible PeLED devices.
Conventional artificial-intelligence vision technology uses separate sensing, computing, and storage units to process vision data. The frequent movement of redundant data between sensors, processors and memory results in high power consumption and latency. Scientists in China designed a novel device, in which photoexcited carriers and ion migration are coupled, that can store and read the tunable short-circuit photocurrent in a non-volatile mode. This new concept of device enables all-in-one sensing-memory-computing approaches for neuromorphic vision hardware.
Life’s random rhythms surround us–from the hypnotic, synchronized blinking of fireflies…to the back-and-forth motion of a child’s swing… to slight variations in the otherwise steady lub-dub of the human heart. Now, an international team says it has developed a novel, universal framework for comparing and contrasting those oscillations--regardless of their different underlying mechanisms—which could become a critical step toward someday fully understanding them.

The drugs would be designed to target highly aggressive tumor-forming cancers that too often become terminal such as lung, colon, breast, pancreatic and prostate cancers.

Scientists recently discovered that neutrinos have mass, counter to long-held understanding. This means that neutrinos can change flavor. Now, advances in theory and experiment are helping scientists to determine whether the neutrinos’ charged counterparts—electrons, muons, and tauons—can also change flavor and how future experiments can look for those changes.
