A newly designed robust mechanophore provides early warning against mechanical failure while resisting heat and UV, report researchers from Institute of Science Tokyo. They combined computational chemistry techniques with thermal and photochemical testing to show that their mechanophore scaffold, called DAANAC, stays inert under environmental stress yet emits a clear yellow signal when mechanically activated. This could pave the way for smart, self-reporting materials in construction, transportation, and electronics.

Researchers from the Fritz Haber Institute of the Max Planck Society have unveiled fundamental new insights into the working principles of fuel-cell catalysts. Their study, published in Nature Communications, reveals how multiple steps during the conversion of oxygen (O₂) to water (H₂O) give rise to the overall catalyst kinetics, and how this is related to changes at the catalyst-solution interface. The study constitutes a profound step forward in our understanding of multi-step electrocatalytic reactions.

Through theoretical derivation, researchers have concluded that a simple linear relationship exists between the reactivity of molten salt reactors and the reciprocal of uranium concentration in the fuel salt. This relationship has been validated through numerical simulations, demonstrating its general applicability, which is expected to have a far-reaching impact on the theoretical development of reactor physics.

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires precise coordination; otherwise, the embryo could develop serious complications. Scientists at ISTA have now demonstrated that the zebrafish eggs, in particular their curvature, might be the instruction manual that keeps cell division on schedule and activates the appropriate genes in a patterned manner to direct correct cell fate acquisition. These insights, published in Nature Physics, could help improve the accuracy of embryo assessments in IVF.

Researchers at Kumamoto University, in collaboration with colleagues in South Korea and Taiwan, have discovered that a unique cobalt-based molecule with metal–metal bonds can function as a spin quantum bit (spin qubit)—a fundamental unit for future quantum computers. The findings provide a new design strategy for molecular materials used in quantum information technologies.

Researchers able to track for the first time how a particularly active region of the sun develops over three solar rotations using two space probes.

Such observations help to better predict space weather.

The super -active region triggered the strongest solar storm observed in the last twenty years in May 2024.

Solar storms have the potential to cause significant disruption to modern technologies, including navigation, communication, and power systems.
