For decades, Arieh Warshel, USC Distinguished Professor of Chemistry and a 2013 Nobel laureate, has used computer simulations to understand how enzymes—fundamental to nearly every biological process ...

Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular ...

Scientists have identified a small flaw in the enzyme GPX4 that prevents neurons from defending themselves. This mutation, ...

For years, ETH researchers have been investigating a molecular complex that plays a key role in protein synthesis. They have ...

Natural biological systems cannot efficiently convert waste CO₂ or its derivatives into useful building-block chemicals at a scale that can keep pace with rising atmospheric carbon. Engineer a fully ...

Researchers discovered that a tiny structural feature of the enzyme GPX4 helps keep neurons safe. A rare mutation removes this protection, allowing harmful molecules to damage cell membranes and ...

And now more cities are implementing curbside composting to help them meet their sustainability goals. New York is currently rolling out a mandatory composting program that will soon be effect in ...

Dr. Anju Goel, MD, MPH, is a public health consultant and physician with more than 10 years of experience in the California public health system. The pancreas is an organ that makes enzymes for ...

RFdiffusion2, RFdiffusion3, and Riff-Diff each solve different structural problems in computational enzyme design ...

Enzymes that originally evolved in high-temperature environments later adapted to cooler conditions as Earth underwent global cooling. Now, researchers from Waseda University and RIKEN in Japan have ...
