How “Empty Space” Is Supercharging Atomically Thin Semiconductors
SPIE–International Society for Optics and Photonics / SciTechDaily
A single layer of atoms may seem too thin to meaningfully interact with light, yet materials like tungsten disulfide are reshaping what is possible in nanophotonics. Researchers have now found a way to dramatically strengthen these interactions.
Atomically thin semiconductors such as tungsten disulfide (WS₂) are emerging as key materials for next-generation photonic technologies. Although they consist of just a single layer of atoms, they support tightly bound excitons, which are electron-hole pairs that interact strongly with light. These materials can also produce new colors of light through nonlinear optical effects such as second-harmonic generation. Because of these capabilities, they are considered promising for quantum optics, sensing, and compact on-chip light sources.
However, their atomic-scale thickness also presents a fundamental challenge. With so little material present, light has limited opportunity to interact with it. As a result, light emission and frequency conversion processes are typically weak unless the surrounding optical environment is carefully designed to boost these interactions. Read more here.

Don’t Panic Yet: “Humanity’s Last Exam” Has Begun
By Texas A&M University – SciTechDaily
As artificial intelligence systems rapidly outgrow traditional academic benchmarks, researchers have unveiled an ambitious new test designed to probe the true limits of machine intelligence.
When advanced artificial intelligence systems began scoring near-perfect marks on established academic tests, researchers recognized a growing concern. The exams that once posed serious challenges were no longer difficult enough to meaningfully evaluate cutting-edge AI. Well-known benchmarks such as the Massive Multitask Language Understanding (MMLU) exam, previously viewed as rigorous, have become less effective at distinguishing true progress in AI capability.
In response, an international group of nearly 1,000 researchers, including a professor from Texas A&M University, developed a far more demanding assessment. Their goal was to design an exam so comprehensive and grounded in specialized human expertise that today’s AI systems would struggle to…Read more here.

Clean Energy Discovered in the Depths of Old Coal Mines
Richard Dal Monte / University of Victoria / SciTechDaily
Cumberland is testing whether its abandoned coal mines can become a town-wide geothermal network that supports redevelopment, economic growth, and lower emissions.
Cumberland, B.C. was built on coal mining—both literally and practically. For more than 80 years, the industry shaped the village’s economy and identity, employing thousands of workers and exporting millions of tonnes of coal. When the mines closed, they left behind vast underground workings and a community searching for a new economic direction.
Today, Cumberland is looking beneath its streets for that next chapter. In partnership with the University of Victoria-led Accelerating Community Energy Transformation (ACET) initiative, the village is exploring how its abandoned mine network could anchor a shift to clean energy.
At the center of the effort is the Cumberland District Energy project. Researchers are studying whether water that has collected in the old mine shafts and tunnels can be used as a geothermal resource to heat and cool local buildings. Read more here.

Forget IQ: This One Surprising Skill Predicts if You’ll Fall for AI Fakes
By Mary-Lou Watkinson, Vanderbilt University – SciTechDaily
People with stronger object recognition skills are better at spotting AI-generated faces, according to new research. Intelligence and AI familiarity did not predict performance.
Could you reliably spot a computer-generated face in a lineup of real people?
As synthetic images become more common across news feeds and social platforms, the ability to separate authentic photos from AI creations is becoming increasingly important.
New research shows that one specific visual skill makes a measurable difference. People who are better at object recognition, meaning they can distinguish between visually similar objects with high accuracy, are also more likely to identify AI-generated faces correctly. The stronger this ability, the more accurately a person can tell whether a face is real or artificial. The study was conducted by Isabel Gauthier, David K. Wilson Chair and Professor of Psychology at Vanderbilt University, along with Jason Chow, Ph.D.’24, and Rankin McGugin, former research assistant professor in the Department of Psychology.
