An ancient biological enzyme known as nickel-iron hydrogenase may play a key role in producing hydrogen for a renewables-based energy economy, researchers said. Careful study of the enzyme has led ...

CHAPEL HILL – All biological reactions within human cells depend on enzymes. Their power as catalysts enables biological reactions to occur usually in milliseconds. But how slowly would these ...

Research has chemists one step closer to recreating nature's most efficient machinery for generating hydrogen gas. This new development may help clear the path for the hydrogen fuel industry to move ...

However, conventional chemical synthesis methods have many side reactions and high environmental burdens, and existing ...

An epigenetic sensor uses a 21st amino acid to illuminate protein dynamics in real time to observe changes within cells.

Saxitoxin—a compound made by marine microbes that can contaminate shellfish—is a toxin so potent that minute quantities can prove deadly. Its mode of action means that less toxic versions have ...

The economic turmoil unleashed by the Covid-19 pandemic and compounded by the war in Ukraine has resulted in disruption of global supply chains marked by shortages and skyrocketing prices of key raw ...

The goal of gene therapy is to permanently cure hereditary diseases. One of the most promising technologies for this is the ...

Preserving DNA in biological samples has long posed a challenge for researchers, but the process may be about to get a lot ...

Bacteria love moist surfaces. Once they have settled there, they do not live as solitary organisms but form larger communities that are embedded in a protective film. These biofilms are found on ...
