Researchers from the University of Tsukuba demonstrate that the hypnotic and teratogenic effects of thalidomide are separable. Thalidomide is a medication with several different effects, one of which is promoting sleep in the context of insomnia. In a new study, researchers from the University of Tsukuba have discovered that thalidomide exerts its hypnotic effects through mechanisms distinct from those for the drug’s notorious teratogenicity. These are striking results showing how thalidomide induces sleep independently of its known effects on the teratogenic cereblon pathway. These findings could be helpful in developing novel thalidomide-like hypnotic drugs without thalidomide’s teratogenic effects. The study was published in the scientific journal Proceedings of the National Academy of Sciences of the United States of America.

Researchers at Kanazawa University report in ACS Nano a high-speed atomic-force microscopy study of the formation of protein fibrils (amyloids) associated with pathologies in collaborated research with Showa University. Mixing different variants of a single protein and changing the acidity of its environment is shown to result in significant variations in amyloid structure and elongation rates.

A research team from the School of Life Sciences at The Chinese University of Hong Kong (CUHK) has developed a novel method for extracting enzymes from bacteria, which lowers the production cost yet improves the enzyme’s stability. It also opens up a new avenue for the enzymatic production of biodiesel, an eco-friendly and effective substitute for fossil fuels. The research findings were recently published in the Journal of the American Chemical Society.
