University of B.C. researchers have developed a groundbreaking coating that could make medical devices safer for millions of patients, reducing the risks associated with blood clots and dangerous bleeding. The new material is designed to mimic the natural behavior of blood vessels so that catheters, stents, blood-oxygenation machines and dialysis machines won't trigger clotting by activating certain proteins in the blood. 

Scientists at EPFL have advanced their NeuroMechFly model, simulating fruit fly movement in the real world. With integrated vision and smell, NeuroMechFly v2 helps us understand brain-body coordination, setting a path for neuroengineering's role in robotics and AI.

This work introduces a novel tandem hydrothermal-calcination synthesis strategy to construct a p-n heterojunction between ultrasmall Te nanoparticles and CN nanosheets. The optimized Te/CN-NH₃ catalyst exhibits outstanding photocatalytic CO₂ reduction activity and stability, achieving nearly 100% CO selectivity and a yield of 92.0 μmol g^-1 h^-1—four times higher than that of pure CN.

Last year, Longyearbyen recorded an average July temperature over 10°C, challenging the traditional polar climate definition that typically inhibits tree growth. This trend continued with record-high temperatures in Svalbard and East Finnmark in 2024, where COAT weather stations on the Varanger Peninsula recorded temperatures 3-4 degrees above the tree growth threshold.

These temperature records are not random. Statistical analysis shows that such high temperatures in Vardø and Longyearbyen are extremely rare events, suggesting that recent temperature spikes are linked to ongoing Arctic climate changes rather than yearly weather variability.

Recent studies have refined the criteria for tree growth in Arctic regions, indicating that a combination of the length of the growing season and average temperature is more accurate than the classical 10-degree rule. For instance, the growing season should last at least 94 days with temperatures above 0.9°C, and the average temperature should be at least 6.4°C. These conditions were met in both 2023 and 2024 at various COAT stations, suggesting potential for tree growth.

However, transitioning from tundra to forest can take centuries, even under suitable climate conditions, due to ecological and biological barriers. Rapid Arctic climate changes necessitate comprehensive ecosystem monitoring, as demonstrated by COAT, to manage and adapt to these transformations effectively.

Exercise can have benefits at the level of neurons, through chemical and mechanical effects, MIT researchers find. The discovery could inform exercise-related therapies for repairing damaged and deteriorating nerves. 

Recently, a team led by Prof. ZHAO Chun and Prof. AN Hong from the University of Science and Technology of China (USTC) conducted a one-month subseasonal forecast experiment using a self-developed global convection-permitting model based on China's Sunway supercomputer, accurately capturing the rainband of the extensive 2020 plum rain events in Japan.
