Worcester Polytechnic Institute (WPI) has been awarded $6.3 million for a groundbreaking initiative that could transform additive manufacturing by enabling the rapid production of high-quality components from scrap metal. This innovative approach to additive manufacturing, aims to ensure that essential components can be produced even in the most resource-limited environments, including where access to traditional supply chains is limited. 

MIT engineers find making hydrogen from soda cans and seawater is scalable and sustainable. Their method’s overall carbon emissions are on par with those of other green hydrogen technologies.

What if your brain had a built-in map – not of places, but of possible futures? Researchers at the Champalimaud Foundation (CF) blend neuroscience and artificial intelligence (AI) to reveal that populations of dopamine neurons in the brain don’t just track whether rewards are coming – they encode maps of when those rewards might arrive and how big they might be.

These maps adapt to context and may help explain how we weigh risks, and why some of us act on impulse while others hold back. Strikingly, this biological mechanism mirrors recent advances in AI, and could inspire new ways for machines to predict, evaluate and adapt to uncertain environments more like we do.

A new way to 3D print complex structures recycles the material used for structural supports, significantly reducing the amount of waste generated.
