Nature knows how to activate and deactivate enzymes on demand, without wasteful protein synthesis and degradation. Surprisingly, methods to do so using tools of chemistry are few. PhD candidate Mireia Casanovas Montasell, Prof. Alexander N. Zelikin and colleagues address this challenge in their new publication, published in Nature Communications.

Researchers at Aarhus University have developed a new and inexpensive way of breaking down polyurethane (PU) plastic into its original components, which can be recycled into new PU material instead of ending up as landfill or in an incinerator.

Geckos are an interesting species. They climb walls and ceilings and do not seem to have any problems with it. But how can that be? PhD Mette Heidemann Rasmussen, Associate Professor Tobias Weidner and their colleagues might have come a bit closer to an answer with their new article in Biology Letters.
