Quantum light breakthrough could transform technology

Scientists have achieved a breakthrough in light manipulation by using topological insulators to generate both even and odd terahertz frequencies through high-order harmonic generation (HHG). By embedding these exotic materials into nanostructured resonators, the team was able to amplify light in unprecedented ways, confirming long-theorized quantum effects. This discovery opens the door to new terahertz technologies with vast implications for ultrafast electronics, wireless communication, and quantum computing.

Week in review: WSUS vulnerability exploited to drop Skuld infostealer, PoC for BIND 9 DNS flaw published

Here’s an overview of some of last week’s most interesting news, articles, interviews and videos: Can your earbuds recognize you? Researchers are working on it Biometric authentication has moved from fingerprints to voices to facial scans, but a team of researchers believes the next step could be inside the ear. New research explores how the ear canal’s unique acoustic properties can be used to verify identity through wireless earbuds. Their system, called EarID, shows that … More → The post Week in review: WSUS vulnerability exploited to drop Skuld infostealer, PoC for BIND 9 DNS flaw published appeared first on Help Net Security.

Too much screen time may be hurting kids’ hearts

More screen time among children and teens is linked to higher risks of heart and metabolic problems, particularly when combined with insufficient sleep. Danish researchers discovered a measurable rise in cardiometabolic risk scores and a metabolic “fingerprint” in frequent screen users. Experts say better sleep and balanced daily routines can help offset these effects and safeguard lifelong health.
