New research from northern Scandinavia and Svalbard reveals that Arctic lakes could emit more methane as climate change increases lake and ecosystem productivity. The study highlights how even modest warming can drive greenhouse gas emissions from Arctic sediments—fuelled by lake algal production and plant growth around the lakes.

In IJEM, a new method for the production of high specific strength SiC-based ceramics at a relatively low sintering temperature (1100 °C) is proposed. Low-temperature sintering of SiC-based ceramics can be achieved by introducing a high content of polysiloxane (PSO) solution (75% by weight). At the same time, the introduction of silicon oxidized carbon (SiOC) phase greatly reduces the anisotropy in the mechanical properties of SiC ceramics. This method provides insights for forming SiC-based ceramics by low-temperature primary sintering and provides a new reference for controlling the anisotropy of vat polymerization ceramic parts.

Once current scientific limitations are overcome, AI-powered digital twins could become a transformative solution to the urgent challenge of shifting from fossil fuels to renewable and environmentally sustainable energy sources.

A team of researchers at the Max Born Institute and collaborating institutions has developed a reliable method to create complex magnetic textures, known as skyrmion bags, in thin ferromagnetic films. Skyrmion bags are donut-like, topologically rich spin textures that go beyond the widely studied single skyrmions.

Researchers from Okayama University of Science and collaborating institutions have experimentally demonstrated the mathematical relationship between the number of collisions and the value of pi (π). By suspending the objects to minimize friction, the team successfully observed 31 collisions at a 1:100 mass ratio—corresponding to 3.1, the first decimal place of π—confirming that pi can be derived in real-world experiments.
