Researchers Mitsuyoshi Kamba, Naoki Hara, and Kiyotaka Aikawa of the University of Tokyo have successfully demonstrated quantum squeezing of the motion of a nanoscale particle, a motion whose uncertainty is smaller than that of quantum mechanical fluctuations. As enhancing the measurement precision of sensors is vital in many modern technologies, the achievement paves the way not only for basic research in fundamental physics but also for applications such as accurate autonomous driving and navigation without a GPS signal. The findings were published in the journal Science.

A pioneering team of scientists at Simon Fraser University have created a new type of silicon-based quantum device controlled both optically and electrically, marking the latest breakthrough in the global quantum computing race.

Published in the journal Nature Photonics, researchers at the SFU Silicon Quantum Technology Lab and leading Canada-based quantum company Photonic Inc. reveal new diode nanocavity devices for electrical control over silicon colour centre qubits.

The devices have achieved the first-ever demonstration of an electrically-injected single-photon source in silicon. The breakthrough clears another hurdle toward building a quantum computer – which has enormous potential to provide computing power well beyond that of today’s supercomputers and advance fields like chemistry, materials science, medicine and cybersecurity.

Researchers at the ESRF - the European Synchrotron-, together with CNRS, ENS Lyon and the Institute of Marine Research in Norway, have unveiled how Atlantic Bluefin tuna transforms the toxic form of mercury into less harmful forms. Their study, published in Environmental Science & Technology, shows that the tuna’s edible muscle contains not only toxic methylmercury, but also mercury bound in stable, non-toxic compounds.

Symmetric solid oxide fuel cells (SSOFCs) have emerged as promising energy conversion devices due to their low fabrication cost and outstanding durability. Ammonia (NH₃), a carbon‑free hydrogen carrier with high energy density and ease of storage, serves as an ideal fuel for such systems. In this study, a bifunctional electrode material, Pr_0.32Sr_0.48Fe_0.75Ni_0.2Ru_0.05O_3-δ (PSFNRu), is synthesized by doping 5 mol% Ru into the parent perovskite Pr_0.32Sr_0.48Fe_0.8Ni_0.2O_3-δ (PSFN). The resulting PSFNRu exhibits abundant oxygen vacancies and enables the in‑situ exsolution of alloy nanoparticles (ANPs) under reducing conditions, which act as additional active sites to enhance electrochemical performance. The PSFNRu‑based SSOFC delivers peak power densities of 736 mW cm^-2 with H₂ and 547 mW cm^-2 with NH₃ at 800 °C, significantly outperforming its undoped counterpart. Furthermore, the cell maintains stable performance for over 172 h at 700 °C under NH₃ fuel, confirming excellent operational durability. These findings underscore the potential of PSFNRu as a high‑performance symmetric electrode for direct ammonia SSOFCs (DA‑SSOFCs).

Researchers at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, report in ACS Nano, how proteins in cells can be controllably activated through heating, an effect that can be used to initiate programmed cell death.
