For quantum computers to function, they must be kept at extremely low temperatures. However, today’s cooling systems also generate noise that interferes with the fragile quantum information they are meant to protect. Now, researchers at Chalmers University of Technology in Sweden have developed an entirely new type of minimal quantum "refrigerator", which is partly driven by the noise itself. This refrigerator enables very precise control over heat and energy flows and could play an important role in scaling up quantum technology.

A surface capable of responding to chemical signals generated by microorganisms and automatically producing biocidal substances – this is not a futuristic vision, but a description of how the B-STING silica nanocomposite works. The new material, developed at the Institute of Nuclear Physics Polish Academy of Sciences in Cracow, acts as a nanofactory of reactive oxygen species, activating itself only when necessary.

RNA viruses' rapid evolution challenges conventional diagnostics like reverse transcription quantitative polymerase chain reaction, as mutations can cause detection failures. Researchers from the Shenzhen Institute of Advanced Technology prospected a dual-strategy for RNA virus detection in Medicine Plus: mutation-tolerant broad screening and precise variant discrimination. Integrating these into portable, multiplex devices using real-time genomic data is key for effective public health responses.

Organic field-effect transistors are promising for highly sensitive portable gas sensors, but their practical application is limited by the atmospheric instability of organic semiconductors. This instability eventually leads to reduced device performance, contributing to growing electronic waste. To address this issue, researchers, through careful solvent engineering, have now developed a new class of eco-friendly, high-performance, and durable organic gas sensors using biodegradable polymers.
