Researchers at Tohoku University have created a yttrium‑doped nickel‑ceria catalyst (Ni₁Ce₁₋ₓYₓOα) that dramatically improves ammonia decomposition into hydrogen. The yttrium addition generates stable surface oxygen vacancies and tunes the electronic structure around nickel sites, lowering reaction energy barriers. The optimized Ni₁Ce₀.₅Y₀.₅Oα composition outperforms existing non‑noble‑metal catalysts and remains structurally stable at 500 °C. This low‑cost catalyst offers a practical route to carbon‑free hydrogen production.
A Swiss research initiative, TailorX, has advanced the synthesis, modeling, and sustainable production of MXenes, a versatile class of 2‑D transition‑metal carbides and nitrides. The team built a high‑purity library of MAX‑phase precursors, deployed AI models to predict MXene structures...
Researchers have introduced INSITE, an injectable platform that combines primary human hepatocytes with hydrogel microspheres to form self‑assembling, vascularizable tissue ensembles in situ. Using ultrasound guidance, the scaffold is delivered to an ectopic site where it integrates with host vasculature...

NASA’s ESCAPADE mission has activated its twin science instruments to study how the solar wind stripped Mars of its atmosphere, turning a once‑wet world into a barren desert. Launched on 13 Nov 2025, the dual‑orbiter pair is the first to operate together...

UC San Diego engineers have built a brain‑inspired hardware platform that merges memory and computation on a single chip. The device uses hydrogen‑doped perovskite nickelate to create nodes that store and process signals together, enabling spatiotemporal computing. In simulations it...

Researchers introduced a quantum key distribution protocol that leverages indefinite causal order, a form of causal nonseparability. In ideal conditions the scheme attains an 85.35% bit‑matching probability, corresponding to a 14.65% raw error rate suitable for standard error‑correction codes. The...

A UCLA‑Princeton team demonstrated that Loss‑DiVincenzo single‑spin qubits in a three‑qubit processor exhibit a strictly linear relationship between microwave drive amplitude and Rabi frequency, even when all qubits are driven simultaneously. The study resolved earlier reports of non‑linearities, showing frequency...

Researchers at the Polish Academy of Sciences have shown that introducing non‑Hermitian dynamics into altermagnetic materials creates previously inaccessible magnetic susceptibility components. By engineering gain and loss at an interface with a ferromagnetic lead, they can selectively amplify or attenuate...

Researchers demonstrated that two entanglement measures respond predictably to modular flow, a real‑time evolution driven by the entanglement Hamiltonian. They unified these responses in a single generating function that generalises the Rényi commutator and directly encodes chiral topological invariants such...
Researchers have demonstrated that graphene oxide (GO) selectively kills bacteria by forming hydrogen bonds with a phospholipid, POPG, found only in bacterial membranes. The study shows that GO’s oxygen‑rich surface is essential for this activity, achieving over 99% suppression of...
Researchers at Kyushu University used atomic force microscopy to directly visualize the motion of individual polymer chain segments on solid surfaces. They identified three distinct dynamic states—thermally activated, thermally suppressed, and a switching state that alternates between the two—revealing non‑equilibrium...

Earth scientist Kate Marvel’s new book, *Human Nature: Nine Ways to Feel about Our Changing Planet*, blends climate science with personal emotion, arguing that scientists need not hide their feelings. Each chapter explores a different emotion—wonder, anger, hope, fear—to make...
Researchers have demonstrated that mesenchymal stromal cells (MSCs) can actively internalize isolated, functional mitochondria through endocytic pathways. The study shows that the internalized organelles retain structural integrity and boost cellular proliferation, stress tolerance, and oxygen consumption. Chemical inhibition of endocytosis...

The latest U.S. winter showed a stark east‑west temperature split, with the Northeast experiencing colder‑than‑average conditions while the Southwest recorded its hottest winter on record, surpassing the previous high by 2.5 °F. A map of state‑by‑state anomalies highlighted more hot‑than‑cold deviations...

Song and Levine (2025) introduce a "covariance criteria" that ties the covariance of gain and loss processes to observed population abundance, providing a model‑structure test for ecological time‑series. Borrowed from queueing theory and later used in biophysics, the method works...
