Deep beneath island arcs, new research suggests that gold enrichment originates from repeated, high-degree melting of a hydrous mantle rather than a single process.

Galactic magnetic fields may arise surprisingly fast, driven by collapsing plasma and turbulent flows.

36 npm packages disguised as Strapi plugins exploit Redis and PostgreSQL via postinstall scripts, enabling persistent access and data theft.

Microsoft has resolved a known issue that was preventing some Classic Outlook users from sending emails via Outlook.com.

As the company explained when it acknowledged the issue last week, affected users were being warned that some of their messages hadn’t reached intended recipients.

Microsoft said that those experiencing this issue would encounter it more often when the Outlook.com account they used to send emails was an Outlook profile linked to another Exchange account.

Aughts excellence.

A massive new analysis of over 1,700 languages shows that some long-debated “universal” grammar rules are actually real. By using cutting-edge evolutionary methods, researchers found that languages tend to evolve in predictable ways rather than randomly. Key patterns—like word order and grammatical structure—keep reappearing across the globe. The results suggest shared human thinking and communication pressures shape how all languages develop.

Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long distances. To overcome this challenge, structured light beams have been developed, whose amplitude, phase, and polarization can be carefully controlled.

Among these are Bessel beams, which are generated by the self-interference of laser beams as they propagate through space. However, ideal Bessel beams possess complex ring structures that complicate their practical use. Additionally, existing methods for generating advanced beam shapes, such as optical bottle beams, often involve complex and expensive setups that necessitate precise alignment.

Now, researchers at Chiba University, Japan, have developed a simple and compact method to generate a laser chain beam that remains nondiffracting during free-space propagation.

Researchers have discovered that perovskite crystals can rapidly and reversibly change shape when exposed to light, revealing a unique behavior not seen in traditional semiconductors.
