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 ...

In addition to conventional secreted factors, cells also secrete ncRNA molecules (RNAkines). The molecular types of secreted factor are in bold, and representative examples or subfamilies, such as ...

A version of this story appeared in Volume 103, Issue 11 Chemists and chemical biologists just keep dreaming up new ways to interfere with biomolecules. That research frequently leads to promising ...

Kidney stones are solid deposits of minerals that can form in the kidneys, also known as renal calculi. They can be made up of various types of crystals, with the most abundant crystal determining the ...

Much of the world we see around us is made up of complicated molecules. If you go to the store, virtually everything you see—every bottle of nail polish, every bag of lawn fertilizer, and every ...

Proteins are important molecules—but they aren’t the only molecules in a cell, and they don’t operate alone. In a new preprint, the team behind the protein structure prediction software RoseTTAFold ...

Efforts to build a better digital “nose” suggest that our perception of scents reflects both the structure of aromatic molecules and the metabolic processes that make them. Alex Wiltschko began ...

A treasure trove of molecules has turned up in two galaxies that we see as they were over 12 billion years ago, revealing information about how the ancient realms form stars. The two galaxies were ...

With the ability to map dozens of biomarkers at once, a new method could transform testing for conditions including heart disease and cancer. With the ability to map dozens of biomarkers at once, a ...
