Cosmic Metal: The Solution to Rare-Earth Metal Shortage

Tetrataenite, a cosmic metal found in meteorites, may offer a solution to the rare earths crisis. Rare earth metals are essential for renewable infrastructure but are difficult to mine and are dominated by China. Researchers at the University of Cambridge have discovered a simple way to mass-produce tetrataenite by adding phosphorus to iron-nickel alloys, eliminating the need for millions of years of cooling. While further research is needed to determine if tetrataenite possesses the necessary magnetic qualities, this discovery highlights the potential for alternative materials in the renewable energy sector.

Unlocking Antiferromagnets: A Revolutionary Approach to Computer Memory

Scientists at Nanyang Technological University, Singapore have made a breakthrough in reading data stored in antiferromagnetic materials, which could be used as an alternative to traditional silicon-based computer memory chips. By passing a current through the antiferromagnets at ultra-low temperatures, researchers were able to measure a unique voltage that indicated whether the material was coded as 1 or 0. This discovery provides a practical method for reading data stored in antiferromagnets, which are potentially more energy efficient and less susceptible to corruption than traditional magnetic materials. The research opens up possibilities for faster and more efficient computer memory in the future.

UN lays out plan to reduce global plastic pollution by 80% by 2040

The United Nations Environment Programme has released a report outlining a roadmap for governments and businesses to reduce plastic pollution by 80% by 2040. The report recommends promoting reuse of plastics, scaling up recycling levels, and discontinuing fossil fuel subsidies that make new plastic products cheaper. The use of appropriate alternative materials for single-use products could also reduce plastic pollution. The investment needed for the changes is estimated to cost around $65 billion a year, but moving to an economy where plastic is reused and recycled could bring $3.25 trillion in savings by 2040.
