Programmable nanospheres unlock nature’s 500-million-year-old color secrets

Half a billion years ago, nature evolved a remarkable trick: generating vibrant, shimmering colors via intricate, microscopic structures in feathers, wings and shells that reflect light in precise ways. Now, researchers from Trinity have taken a major step forward in harnessing it for advanced materials science.

A team led by Professor Colm Delaney from Trinity’s School of Chemistry and AMBER, the Research Ireland Center for Advanced Materials and BioEngineering Research, has developed a pioneering method, inspired by nature, to create and program structural colors using a cutting-edge microfabrication technique.

The work could have major implications for environmental sensing, biomedical diagnostics, and photonic materials. The research is published in the journal Advanced Materials.

Columbia scientists turn yogurt into a healing gel that mimics human tissue

Scientists at Columbia Engineering have developed an injectable hydrogel made from yogurt-derived extracellular vesicles (EVs) that could revolutionize regenerative medicine. These EVs serve both as healing agents and as structural components, eliminating the need for added chemicals. The innovation leverages everyday dairy products like yogurt to create a biocompatible material that mimics natural tissue and enhances healing.

A qualitative systematic review on AI empowered self-regulated learning in higher education

npj Science of Learning — A qualitative systematic review on AI empowered self-regulated learning (SRL) in higher education. Aiming to synthesize empirical studies, we employed a qualitative approach to scrutinize AI’s role in supporting SRL processes. Through a meticulous selection process adhering to PRISMA guidelines, we identified 14 distinct studies that leveraged AI applications, including chatbots, adaptive feedback systems, serious games, and e-textbooks, to support student autonomy. Our findings reveal a nuanced landscape where AI demonstrates potential in facilitating SRL’s forethought, performance, and reflection phases, yet also highlights whether the agency is human-centered or AI-centered leading to variations in the SRL model. This review underscores the imperative for balanced AI integration, ensuring technological advantages are harnessed without undermining student self-efficacy. The implications suggest a future where AI is a thoughtfully woven thread in the SRL fabric of higher education, calling for further research to optimize this synergy.

The battery-powered Starlink Mini is here

Starlink is a life-changing Internet service that connects people and villages too remote for towers and cables to reach. My own Starlink Mini has been critical in helping me pursue life as a digital nomad from almost anywhere in Europe. And right now, Starlink’s the only game in town for relatively cheap and fast consumer internet that can be quickly deployed into data dead spots.

My overriding thought after using the PeakDo LinkPower for the last few weeks is this: why doesn’t SpaceX make one of these?
