Lithium-6 is essential for producing nuclear fusion fuel, but isolating it from the much more common isotope, lithium-7, usually requires liquid mercury, which is extremely toxic. Now, researchers have developed a mercury-free method to isolate lithium-6 that is as effective as the conventional method. The new method is presented March 20 in the Cell Press journal Chem.

Researchers from MIT and NVIDIA developed a hybrid AI approach that can generate realistic images with the same or better quality than state-of-the-art diffusion models, but that runs about nine times faster and uses fewer computational resources. The tool uses an autoregressive model to quickly capture the big picture and then a small diffusion model to refine the details of the image.

A study in Forest Ecosystems reveals that Australia's cool temperate rainforests are more disturbance-resilient than previously thought. Researchers found that Nothofagus moorei thrives under higher disturbance intensities through basal coppicing. 60% of species can resprout after disturbance, with N. moorei showing faster growth and better recruitment in response to canopy removal. These findings suggest that conservation strategies should not completely exclude disturbance but instead use controlled burning and selective logging to maintain ecological diversity.A study in Forest Ecosystems reveals that Australia's cool temperate rainforests are more disturbance-resilient than previously thought.
