The polysaccharides outperformed vitamin C in eliminating free radicals, making them promising for application in functional cosmetics.
Most medical large language models offer little better than guesses when it comes to interpreting medical information. ChatGPT-4 achieved the best performance, but its accuracy remained insufficient for some medical code questions. The study highlights the need for broader clinical language in models and caution in their widespread use.
A seminal life cycle assessment (LCA) study found that diagnostic services generate the equivalent of nearly 1,100 gas-powered cars annually, with CT scans accounting for the majority of GHG emissions. The team identified areas to reduce energy consumption and greenhouse gas emissions without compromising patient care.
Professor Chiyoung Park's team created a supramolecular photocatalyst that converts sunlight into chemical energy, producing hydrogen. The system was combined with Shewanella oneidensis MR-1 to produce ascorbic acid into hydrogen continuously under sunlight. This technology has the potential to provide sustainable energy solutions.
A global study using teabags to measure carbon release from soil in wetlands found that warmer temperatures led to increased decay of organic matter, reducing carbon preservation. Freshwater and tidal marshes showed the highest potential for carbon storage.
