Illinois researchers examine teens’ use of generative AI, safety concerns

Researchers found that teenagers use generative artificial intelligence for emotional support, social interactions, and academic purposes. However, they also reported significant misconceptions about generative AI among parents and children. Parents had little to no understanding of their children's use of GAI, and they viewed AI as a ...

New 3D printing approach means better biomedical, energy, robotics devices

Researchers at Oregon State University have developed a new 3D printing technique that allows for the creation of shape-changing materials with muscle-like properties. These materials can crawl, fold, and snap directly after printing, enabling their use in implantable medical devices, soft robotics, and energy storage applications.

Bendable electronic parts heat up by themselves like “heat pack” and lower the manufacturing temperature barrier!

Scientists at DGIST have created a technology to manufacture high-performance liquid process-based electronic parts at lower temperatures than before. This innovation harnesses the 'heat of combustion' generated in materials, enabling the production of robust yet flexible electronic components for wearable devices and smart products.

Exploring sea buckthorn polysaccharides for next-generation skincare applications

Researchers isolated three purified polysaccharide fractions from sea buckthorn and found them to have good thermal stability, antioxidant activity, and reducing capabilities. The polysaccharides outperformed vitamin C in eliminating free radicals, making them promising for application in functional cosmetics.

Which AI model best deciphers medical information?

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.

VUMC and Philips landmark emissions assessment of a radiology department published in premier industry journal

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.

Artificial photosynthesis learned from nature! Successfully developed new solar hydrogen production technology

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.

Planetary boundaries: Confronting the global crisis of land degradation; Potsdam institute report opens UNCCD COP 16

The report charts a course correction for how the world grows food and uses land, highlighting the central role of land in maintaining Earth's stability. Land degradation is undermining the planet's capacity to support humanity, with seven out of nine planetary boundaries negatively impacted by unsustainable land use.

Deadly diets driving digestive diseases

Researchers urge people to improve their eating habits to reduce the risk of bowel cancer, citing evidence that high-fibre foods promote healthy gut bacteria. Studies found a link between poor diet choices and digestive cancers, highlighting the importance of diets rich in whole grains, vegetables, fruits, and legumes.
