The U.S. Naval Research Laboratory and the Fermi Large Area Telescope Collaboration have discovered nearly 300 gamma ray pulsars, advancing pulsar research and contributing to gravitational wave studies and navigation applications. The findings also include insights into “spider” pulsars, where a neutron star interacts intensively with its binary companion.

The U.S. Naval Research Laboratory (NRL), in conjunction with the international Fermi Large Area Telescope Collaboration, has announced the discovery of almost 300 gamma ray pulsars. This announcement was made in their Third Catalog of Gamma Ray Pulsars, marking a significant achievement 15 years after the 2008 launch of the Fermi telescope. At the time of Fermi’s launch, there were less than ten known gamma-ray pulsars.

“Work on this important catalog has been going on in our group for years,” said Paul Ray, Ph.D., head of the High Energy Astrophysics and Applications Section at NRL. “Our scientists and postdocs have been able to both discover and analyze the timing behavior and spectra of many of these newfound pulsars as part of our quest to further our understanding of these exotic stars that we are able to use as cosmic clocks.”

The DragonFire laser-directed energy weapon (LDEW) system has achieved the UK’s first high-power firing of a laser weapon against aerial targets during a trial at the MOD’s Hebrides Range.

The DragonFire is a line-of-sight weapon and can engage with any visible target, and its range is classified. The system is able to deliver a high-power laser over long ranges and requires precision equivalent to hitting a £1 coin from a kilometer away.

Laser-directed energy weapons are incredibly powerful and can engage targets at lightning-fast speeds. They use a concentrated beam of light to cut through their target, resulting in structural failure or other devastating outcomes if the warhead is targeted.

Organic-based optoelectronic technology is increasingly recognized as an energy-efficient solution for low-power indoor electronics and wireless IoT sensors. This is largely due to its superior flexibility and light weight compared to conventional silicon-based devices. Notably, organic photovoltaic cells (OPVs) and organic photodetectors (OPDs) are leading examples in this field.

OPVs have the remarkable ability to absorb energy and generate electricity even under very low light conditions, while OPDs are capable of capturing images. However, despite their potential, the development of these devices has thus far been conducted independently. As a result, they have not yet reached the level of efficiency necessary to be considered practical for next-generation, miniaturized devices.

A Korea Institute of Science and Technology (KIST) research team, led by Dr. Min-Chul Park and Dr. Do Kyung Hwang of the Center for Opto-Electronic Materials and Devices, Prof. Jae Won Shim and Prof. Tae Geun Kim of the School of Electrical Engineering at Korea University, Prof. JaeHong Park of the Department of Chemistry and Nanoscience at Ewha Womans University, have now developed an organic-based optoelectronic device.

A certain fossil fuel works well as a 2D insulating films that could help launch a new era of semiconductors made with 2D materials.

Research shows 20% boost in seawater desalination efficiency and reducing energy demand – a leap towards eco-friendly water solutions.

A team of engineers at the University of Massachusetts Amherst has recently shown that nearly any material can be turned into a device that continuously harvests electricity from humidity in the air.

Researchers describe the “generic Air-gen effect”—nearly any material can be engineered with nanopores to harvest, cost effective, scalable, interruption-free electricity.

VexTrio, the shadowy entity controlling a massive network of 70,000+ domains, is finally in the spotlight. This “traffic broker” fuels countless scams & malware campaigns, including ClearFake, SocGholish, & more. Read:

The threat actors behind ClearFake, SocGholish, and dozens of other actors have established partnerships with another entity known as VexTrio as part of a massive “criminal affiliate program,” new findings from Infoblox reveal.

The latest development demonstrates the “breadth of their activities and depth of their connections within the cybercrime industry,” the company said, describing VexTrio as the “single largest malicious traffic broker described in security literature.”

With four electric motors each pumping out 240kW of power, BYD’s new Yangwang U7 is a powerful large sedan.

Data-centric applications benefit from dense, low-power memory. Here the authors use a combination of chalcogenide superlattices and nanocomposites to achieve low switching voltage (0.7 V) and fast speed (40 ns) in 40-nm-scale phase-change memory.
