Yongcui Mi has developed a new technology that enables real-time shaping and control of laser beams for laser welding and directed energy deposition using laser and wire. The innovation is based on the same mirror technology used in advanced telescopes for astronomy.

In a few years, this new technology could lead to more efficient and reliable ways of using lasers for welding and directed energy deposition with laser and wire. The manufacturing industry could benefit from new opportunities to build more robust processes that meet stringent quality standards.

“We are the first to use deformable technology for this application. The mirror optics can handle multi-kilowatt laser power, and with the help of computer vision and AI, the laser beam can be shaped in real time to adapt to variations in joint gaps,” explains Yongcui, a newly minted Ph.D. in Production technology from University West.

The search for quantum gravity has gone on for 100 years, but it is not the only unification challenge in physics. Many of us believe that one day there will be a unification theory—a theory that will reconcile many divergent physical theories.

Our new article published in Physica Scripta brings new hope that such a theory exists. It demonstrates that the use of a certain mathematical object called Alena Tensor reconciles various physical theories, including , electrodynamics, and continuum mechanics. Will this finally allow scientists to unify descriptions used in physics?

Researchers have developed a tiny, room-temperature device that creates a special type of structured light called radially polarized photons, which are highly useful for secure communication, advanced imaging, and precision optical tools.

By carefully designing and positioning a quantum dot within a nanoantenna, they achieved high-quality light with more than 93% purity. This breakthrough helps improve the efficiency and practicality of devices that use structured light, paving the way for advancements in and optical technology.

A team led by Prof. Ronen Rapaport from the Racah School of Physics at The Hebrew University of Jerusalem has developed the new device that produces radially polarized photons at room temperature. This advancement offers new possibilities for both classical and quantum communication technologies.

New analysis supports Einstein’s relativity and narrows neutrino mass ranges, hinting at evolving dark energy.

Gravity, the fundamental force sculpting the universe, has shaped tiny variations in matter from the early cosmos into the vast networks of galaxies we see today. Using data from the Dark Energy Spectroscopic Instrument (DESI), scientists have traced the evolution of these cosmic structures over the past 11 billion years. This research represents the most precise large-scale test of gravity ever conducted, offering unprecedented insights into the universe’s formation and behavior.

Introduction to DESI and its global impact.

A vulnerability in WPForms, a WordPress plugin used in over 6 million websites, could allow subscriber-level users to issue arbitrary Stripe refunds or cancel subscriptions.

Tracked under CVE-2024–11205, the flaw was categorized as a high-severity problem due to the authentication prerequisite. However, given that membership systems are available on most sites, exploitation may be fairly easy in most cases.

The issue impacts WPForms from version 1.8.4 and up to 1.9.2.1, with a patch pushed in version 1.9.2.2, released last month.

Microsoft has now partially lifted a compatibility hold blocking the Windows 24H2 update on systems with some Ubisoft games after the French video game publisher has fixed bugs causing crashes, freezes, and audio issues.

The company blocked Windows 24H2 upgrades on PCs with Assassin’s Creed, Star Wars Outlaws, and Avatar: Frontiers of Pandora games more than two weeks ago, following a stream of user reports on Reddit [1, 2] and the Microsoft Answers forums [1, 2, 3] that these games were no longer working correctly.

Windows users affected by this known issue were particularly frustrated as they reported these issues in the Windows Insider Feedback Hub, on Reddit, and other online platforms since Windows 11 24H2 was still in preview.
