Quantum spin model made from nanographene molecules

Researchers have experimentally recreated another fundamental theoretical model from quantum physics, which goes back to the Nobel Prize laureate Werner Heisenberg. The basis for the successful experiment is made of tiny carbon molecules known as nanographenes. This synthetic bottom-up approach enables versatile experimental research into quantum technologies, which could one day help drive breakthroughs in the field.

Researchers develop computational tools to safeguard privacy without degrading voice-based cognitive markers

Digital voice recordings contain valuable information that can indicate an individual’s cognitive health, offering a non-invasive and efficient method for assessment. Research has demonstrated that digital voice measures can detect early signs of cognitive decline by analyzing features such as speech rate, articulation, pitch variation and pauses, which may signal cognitive impairment when deviating from normative patterns. However, voice data introduces privacy challenges due to the personally identifiable information embedded in recordings, such as gender, accent and emotional state, as well as more subtle speech characteristics that can uniquely identify individuals. These risks are amplified when voice data is processed by automated systems, raising concerns about re-identification and potential misuse of data.

Week in review: NIST selects HQC for post-quantum encryption, 10 classic cybersecurity books

Here’s an overview of some of last week’s most interesting news, articles, interviews and videos: NIST selects HQC as backup algorithm for post-quantum encryption Last year, NIST standardized a set of encryption algorithms that can keep data secure from a cyberattack by a future quantum computer. Now, NIST has selected a backup algorithm that can provide a second line of defense for the task of general encryption, which safeguards internet traffic and stored data alike. … More → The post Week in review: NIST selects HQC for post-quantum encryption, 10 classic cybersecurity books appeared first on Help Net Security.

Reading magnetic states faster — in far infrared

With today’s data rates of only a few hundred megabytes per second, access to digital information remains relatively slow. Initial experiments have already shown a promising new strategy: Magnetic states can be read out by short current pulses, whereby recently discovered spintronic effects in purpose-built material systems could remove previous speed restrictions. Researchers are now providing proof of the feasibility of such ultrafast data sources. Instead of electrical pulses, they use ultrashort terahertz light pulses, thereby enabling the read-out of magnetic structures within picoseconds.

ClickFix: How to Infect Your PC in Three Easy Steps

A clever malware deployment scheme first spotted in targeted attacks last year has now gone mainstream. In this scam, dubbed “ClickFix,” the visitor to a hacked or malicious website is asked to distinguish themselves from bots by pressing a combination of keyboard keys that causes Microsoft Windows to download password-stealing malware.

Catching aromaticity in the act: Direct real-time tracking of how ‘excited-state aromaticity’ drives molecular shape changes

Scientists have achieved the first real-time visualization of how ‘excited-state aromaticity’ emerges within just hundreds of femtoseconds and then triggers a molecule to change from bent to planar structure in a few picoseconds. By combining ultrafast electronic and vibrational spectroscopies, the team captured these fleeting structural changes at the molecular level and showed that aromaticity appears before — and then drives — the structural planarization. Their findings lay the groundwork for designing more efficient photoactive materials, such as sensors and light-driven molecular switches, by leveraging the power of aromaticity in excited states.
