An international team of scientists is using porous, sponge-like materials that can trap carbon dioxide in their cavities while allowing other gases such as nitrogen to pass through. The materials are made from sugar and low-cost alkali metal salts, so they would be inexpensive enough for large-scale deployment, and they could be particularly effective for limiting the environmental damage of coal-fired power plants.

New research from Aravinda Thyagarajan outlines a new protocol toward better privacy and security protections when swapping cryptocurrencies. The paper, “Universal Atomic Swaps: Secure Exchange of Coins Across All Blockchains,” is being presented at the 2022 IEEE Symposium on Security and Privacy. Thyagarajan’s protocol addresses security and privacy concerns. First, the protocol is universal — it allows for exchanges across all current and future cryptocurrencies. Second, the swap protocol ensures that the swap will happen honestly or it won’t happen at all, meaning no one will maliciously lose coins, without relying on third parties. And lastly, the protocol supports the exchange of multiple types of coins—e.g. Bitcoin, Ethereum, Dogecoin, etc.—in a single swap.

Hormones are crucial to prevent, treat, and manage many of the world's most common diseases. They are important to good human health and wellbeing. The role of hormonal health and disease in European Health Policies has so far been insufficiently recognized. This is why The European Society of Endocrinology (ESE), together with the European Hormone and Metabolism Foundation – Foundation of the European Society of Endocrinology (ESE Foundation) and its partner societies are therefore launching the first European Hormone Day, on 23 May.
