A research team including research scientist Atsuko Kobayashi from the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology, Japan, and research scientist Mizuho Koike from the Institute of Space and Astronautical Science at Japan Aerospace Exploration Agency, have found nitrogen-bearing organic material in carbonate minerals in a Martian meteorite. This organic material has most likely been preserved for 4 billion…

TAMA300 blazes trail for improved gravitational wave astronomy
Researchers at the National Astronomical Observatory of Japan (NAOJ) have used the infrastructure of the former TAMA300 gravitational wave detector in Mitaka, Tokyo, to demonstrate a new technique to reduce quantum noise in detectors. This new technique will increase the sensitivity of the detectors comprising a collaborative worldwide gravitational wave network, allowing them to observe fainter waves.

Sony Plans Limited PlayStation 5 Output in First Year
Sony plans to produce far fewer units of its upcoming PlayStation 5 in its first year than it had for the previous-generation console’s launch, Bloomberg reported Thursday. From the report: The Tokyo-based tech giant is limiting its initial production run in part because it expects the PS5’s ambitious specs to weigh on demand by leading to a high price at launch,…
Machine learning puts a new spin on spin models
Researchers from Tokyo Metropolitan University have used machine learning to analyze spin models, which are used in physics to study phase transitions. Previous work showed that an image/handwriting classification model could be applied to distinguish states in the simplest models. The team showed the approach is applicable to more complex models and found that an AI trained on one model and…
Glass transition of spins and orbitals of electrons in a pure crystal
A joint research group from Osaka University and the University of Tokyo uncovered the mechanism of the glass transition that electrons can experience in pyrochlore oxide crystals. The researchers show that distortions in the atomic lattice cause two types of rotational degrees of freedom of spins to become coupled and form a glassy state at the exact same temperature. This work…
A filter for cleaner qubits
A research team at the Tokyo Medical and Dental University (TMDU), RIKEN, and the University of Tokyo have demonstrated how to increase the lifetime of qubits inside quantum computers by using an additional “filter” qubit. This work may help make higher fidelity quantum computers that can be used in financial, cryptographic, and chemistry applications. …

A spookily good sensor
Scientists from the Research Center for Advanced Science and Technology (RCAST) at The University of Tokyo demonstrated a method for coupling a magnetic sphere with a sensor via the strange power of quantum entanglement. They showed that the existence of even a single magnetic excitation in the sphere could be detected with a one-shot measurement. This work represents a major advancement…
Phonon hydrodynamics and ultrahigh-room temperature thermal conductivity in thin graphite
Different forms of carbon or allotropes including graphene and diamond are among the best conductors of heat. In a recent report on Science, Yo Machida and a research team in the department of Physics and the Laboratory of Physics and Materials in Tokyo and France monitored the evolution of thermal conductivity in thin graphite. The property evolved as a function of…
