Scientists unveil technique to build ultra-thin material stacks that promise quantum breakthrough

University of Southampton
Peer-Reviewed Publication

Scientists have developed a cleaner and cheaper method for fabricating 2D heterostructures which enables them to precisely layer materials just a few atoms thick. They say it could lead to faster microchips and the development of next-generation quantum computing technologies.

Damage growth in metals under shear loading

Karlsruher Institut für Technologie (KIT)
Peer-Reviewed Publication

The resistance of material against mechanical loads is a decisive factor for component safety – such as in aircraft. Working in an international team, researchers from the Karlsruhe Institute of Technology (KIT) have found a previously unknown damage mechanism in metals: Contamination in the form of stiff particles can make the volume of voids grow up to sixfold when exposed to deformation by shear loading. The results of the study are particularly relevant to the ductility and safety of materials in recycling processes. Publication in the International Journal of Plasticity.

Testing the limits of what’s possible (and what isn’t) with AI

University of Cambridge
Peer-Reviewed Publication

When can we trust the results we get from AI, and when is learning impossible? Researchers have shown that there are some problems that even the most powerful AI can reliably solve, no matter how much data it’s given.

Quantum bath syncs distant qubits

Institute of Science and Technology Austria
Peer-Reviewed Publication

Future quantum computing will require correlations between distant modules—a feature known as distributed entanglement. Traditionally, such entanglement has relied on active control and repeated measurements. Now, physicists at the Institute of Science and Technology Austria (ISTA) have realized a fully autonomous method for distributed entanglement using a “quantum bath” of correlated light particles. Published on Monday in Physical Review X, their work experimentally confirms a 20‑year‑old prediction and could provide a new platform for applied quantum technologies.

New method aims to keep kids safe from illegal AI-generated content

Massachusetts Institute of Technology
Reports and Proceedings

Researchers developed an evaluation procedure that tests generative AI models for harmful capabilities without generating outputs. This could enable auditors to identify open-source models that have been adapted to produce illegal content, like child sexual abuse material (CSAM).

New technique sheds light on longstanding debates about ferroelectric materials

North Carolina State University
Peer-Reviewed Publication

New findings are shedding light on longstanding debates over the behavior of ferroelectric materials when those materials are exposed to electric fields. The findings stem from the use of a novel technique that allows researchers to observe the real-time behavior of domain walls in ferroelectric materials as they are “poled” and “depoled.”

Amyloid PET quantitation and centiloid thresholds in the diagnosis of Alzheimer disease

JAMA Network
Peer-Reviewed Publication

About The Study: In this individual participant data meta-analysis, positivity cutoffs converged around 18 Centiloids (data-driven) and 27 Centiloids (visual reads). Findings from a double-cutoff analysis suggest that scans in the 11 to 26 Centiloid range should be interpreted with caution depending on the context of use.
