A newly discovered fossil from Mongolia’s Gobi Desert reveals a previously unknown genus and species of Cretaceous mammal. Named Ravjaa ishiii, the tiny animal was identified from a partial lower jaw found by a joint team from Okayama University of Science and the Mongolian Academy of Sciences. The find marks the first record of a zhelestid mammal in Mongolia and suggests early mammals may have adapted to eating seeds and fruits from emerging flowering plants. Full findings are published in Acta Palaeontologica Polonica.

Many products in the modern world are in some way fabricated using computer numerical control (CNC) machines, which use computers to automate machine operations in manufacturing. While simple in concept, the ways to instruct these machines is in reality often complex. A team of researchers including those from the University of Tokyo devised a system to demonstrate how to mitigate some of this complexity. Draw2Cut allows users to draw desired designs directly onto material to be cut or milled. In this case, color-coded lines drawn with standard marker pens instruct the Draw2Cut system to mill designs into wood without any prior knowledge of CNC machines or their typical workflows.

Chimpanzee naive pluripotent stem cells (PSCs) can now be grown in cellular cultures, reveals a recent study. They successfully created chimpanzee early embryo models, called ‘blastoids,’ and found that the inhibition of a specific regulatory gene is essential for chimpanzee PSC self-renewal. They also developed a feeder-free culture system, eliminating the need for mouse-derived feeder cells as support. These findings provide valuable insights into primate embryology and could advance stem cell research and regenerative medicine.

Researchers found a strategy to create catalysts that make the production of hydrogen for clean fuel more efficient and affordable.

Strong methods do exist for measuring animal movement in the context of energy expenditure, but these are limited by the physical size of the equipment used. Now, in a paper published in the Journal of Experimental Biology, researchers from the Marine Biophysics Unit at the Okinawa Institute of Science and Technology (OIST), in collaboration with Professor Amatzia Genin from the Hebrew University of Jerusalem, describe an innovative method for measuring energy usage during movement with video and 3D-tracking via deep learning.

Current risk assessment guidelines for ischemic stroke may underestimate patients with mild carotid stenosis. A Japanese multicenter study found that unstable plaque—particularly intraplaque hemorrhage—was a key stroke predictor. Surgical intervention, such as carotid endarterectomy, significantly reduced stroke risk compared to medical therapy alone. These findings could prompt a shift in how physicians assess and treat mild but symptomatic carotid artery disease.

Researchers from The University of Osaka discover new biomarkers at the cell and protein levels for predicting relapse of autoimmune vasculitis before the beginning of treatment. The insights into the disease mechanism and these new biomarkers may lead to better treatment strategies and outcomes for new vasculitis patients.

Carbon-containing meteorites look like they had less severe impacts than those without carbon because the evidence was blasted into space by gases produced during the impact. The Kobe University discovery not only solves a 30-year-old mystery, but also provides guidelines for a future sampling mission to Ceres.

Cationic Ir（III） complex bound to synthetic saponite was used as a donor for TTA-UC（Triplet-triplet annihilation up-conversion）with 9,10-diphenylanthracne.

High quantum yield of TTA-UC was attained due to the hybridization with organically modified synthetic saponite in R-limonene.

Since R-limonene is a natural product belonging to a green solvent, the present finding may promise the possible utility of clay minerals for TTA-UC in green solvents.
