Surface-only superconductor is the strangest of its kind

Something strange goes on inside the material platinum-bismuth-two (PtBi₂). A new study by researchers at IFW Dresden and the Cluster of Excellence ct.qmat demonstrates that while PtBi₂ may look like a typical shiny gray crystal, electrons moving through it do some things never seen before.

In 2024, the research team demonstrated that the top and bottom surfaces of the material superconduct, meaning pair up and move without resistance.

Now, they reveal that this pairing works differently from any superconductor we have seen before. Enticingly, the edges around the superconducting surfaces hold long-sought-after Majorana particles, which may be used as fault-tolerant quantum bits (qubits) in quantum computers.

Acoustic waves could be the key to orbitronic devices

Electronics traditionally rely on harnessing the electron’s charge, but researchers are now exploring the possibility of harnessing its other intrinsic properties. In a Nature Communications study, scientists from Japan demonstrated that sound waves in certain solids can generate orbital currents—flow of electron orbital angular momentum.

Their findings establish a foundation for realizing next-generation “orbitronic” devices using existing acoustic technology.

Since the discovery of electricity, countless advancements in technology have relied on harnessing the electron’s charge, which is the fundamental principle behind most traditional electronics.

JUNO experiment delivers first physics results two months after completion

The Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences has successfully completed the Jiangmen Underground Neutrino Observatory (JUNO) and released its first physics results.

After more than a decade of design, construction, and international collaboration, JUNO has become the world’s first next-generation, large-scale, high-precision neutrino detector to begin operation.

Early data show that the detector’s key performance indicators fully meet or surpass design expectations, confirming that JUNO is ready to deliver frontier measurements in neutrino physics.

Lockheed Martin, Google team up on generative AI

Lockheed Martin is partnering with Google Public Sector to integrate Google’s generative AI technologies, including the Gemini models, into its AI Factory.

Google’s AI tools will be introduced within Lockheed Martin’s secure, on-premises, air-gapped environments, making them accessible to personnel throughout the company.

Python-Based WhatsApp Worm Spreads Eternidade Stealer Across Brazilian Devices

Cybersecurity researchers have disclosed details of a new campaign that leverages a combination of social engineering and WhatsApp hijacking to distribute a Delphi-based banking trojan named Eternidade Stealer as part of attacks targeting users in Brazil.

“It uses Internet Message Access Protocol (IMAP) to dynamically retrieve command-and-control (C2) addresses, allowing the threat actor to update its C2 server,” Trustwave SpiderLabs researchers Nathaniel Morales, John Basmayor, and Nikita Kazymirskyi said in a technical breakdown of the campaign shared with The Hacker News.

It is distributed through a WhatsApp worm campaign, with the actor now deploying a Python script, a shift from previous PowerShell-based scripts to hijack WhatsApp and spread malicious attachments.
