🏛️ New research reveals ancient Roman concrete's durability is boosted by a second chemical process, "carbonation," in addition to the known pozzolanic reaction. This ongoing reaction between atmospheric CO₂ and calcium compounds helps bind and densify the concrete over time.

🔬 Scientists analyzed a concrete latrine at Hadrian's Villa in Italy (2nd century A.D.) using advanced 3D imaging. They found that mineralized carbonation forms calcium carbonate networks, which act as a self-healing mechanism by filling cracks and pores.

💡 This discovery, highlighting how calcite crystals strengthen and seal Roman concrete, could inform the development of more sustainable and resilient modern construction materials, potentially reducing the environmental impact of cement production.

🧫 UC Berkeley and Harvard researchers developed new metamaterials inspired by deep-sea glass sponges. These materials optimize both structural strength and fluid management simultaneously, a breakthrough in design.

🔬 An automated framework integrates mechanical and fluid dynamics simulations to explore complex metamaterial designs, allowing for optimization of structural rigidity and smooth fluid flow, avoiding vibrations.

⚙️ Tests show the new metamaterial increased buckling load by ~140% and reduced vibrations with minimal porosity (5%), demonstrating potential for lightweight, high-performance applications.

* 🥚 Princeton Engineering researchers have developed a new method for creating adjustable shells that can snap into multiple stable shapes, inspired by the geometry of ketchup bottle caps.

* 🤖 This discovery led to a magnetically controlled robot that can roll, crawl, and change shape without motors, by leveraging geometry to encode multiple stable configurations into its structure.

* 💡 The team's work, published June 15, 2026, in the Proceedings of the National Academy of Sciences, uses principles from curved-crease origami and found that structures can naturally form "pseudocreases," creating more stable states than initially predicted.
