Researchers at the University of Michigan have found a new potential benefit of a molecule in green tea: preventing the misfolding of specific proteins in the brain. The aggregation of these proteins, called metal-associated amyloids, is associated with Alzheimer’s disease and other neurodegenerative conditions. A paper published recently in the Proceedings of the National Academy of Sciences explained how U-M Life Sciences Institute faculty member Mi Hee Lim and an interdisciplinary team of researchers used green tea extract to control the generation of metal-associated amyloid-β aggregates associated with Alzheimer’s disease in the lab.

In the future, ultra-high-density non-volatile storage — such as hard drives — could be grown using magnetic bacteria.
This breakthrough, shepherded by researchers from the University of Leeds in the UK and the Tokyo University of Agriculture and Technology, relies on certain strains of bacteria that ingest iron, which is then converted into magnetite (iron II, III oxide), the most magnetic naturally occurring mineral on Earth. These microbes, by following the Earth’s magnetic field, use this built-in magnet to navigate.
To turn this behavior into something that can actually act as magnetic storage, the researchers identified and extracted the protein responsible for converting iron into magnetite — Mms6. A gold substrate is then covered in a checkerboard fashion with chemicals that bind to Mms6, and the substrate is dunked in the protein. The whole caboodle is then washed with an iron solution, turning each of the Mms6 sites into a magnetic bit (pictured above)
