The very first life on earth is thought to have developed from 'protocells' -- liquid mixtures of many different types of molecules. Researchers have now shown that in such mixtures, small imbalances ...

Basic biology textbooks will tell you that all life on Earth is built from four types of molecules: proteins, carbohydrates, lipids, and nucleic acids. And each group is vital for every living ...

One of the central challenges for synthetic chemists is to impose control over free radicals. Highly reactive molecules with an unpaired electron, free radicals may be familiar to you; these are the ...

In patients with severe osteoarthritis, cartilage can wear so thin that joints essentially transform into bone on bone — without a cushion between. A new therapy that uses synthetic nanofibers to ...

Northwestern University researchers almost three years ago introduced an injectable new therapy, which harnessed fast-moving “dancing molecules,” to repair tissues and reverse paralysis after severe ...
