Researchers find some cider makers add unneeded sugar

It's the holiday season and the time of year when there are plenty of libations at nearly every event and or celebration. However, you may not be aware of all the ingredients in your favorite libation, especially if that ...

How do cellular machines unfold misfolded proteins?

Protein chains typically fold to function. Folding is a complex process and if done correctly leads to a unique functional fold topology for a given protein chain. Other topologies are also possible but are often non-functional ...

What's behind smelly wine

Aging often improves the flavor of wine, but sometimes the beverage emerges from storage with an unpleasant smell. One of the prime culprits is hydrogen sulfide (H2S), which can give the affected wine an aroma of sewage or ...

Green production of chemicals for industry

Industry consumes large quantities of crude oil to produce basic substances for drugs, cosmetics, plastics, or food. However, these processes consume a lot of energy and produce waste. Biological processes with enzymes are ...

Obtaining polyester from plant oil

The development of future technologies that are not based on mineral oil and can be used for producing chemicals and plastics is one of the major tasks in modern materials science and a key challenge that needs to be addressed ...
