Design principles for peroxidase-mimicking nanozymes

Nanozymes, enzyme-like catalytic nanomaterials, are considered to be the next generation of enzyme mimics because they not only overcome natural enzymes' intrinsic limitations, but also possess unique properties in comparison ...

New catalyst yields more accurate PSA test

Say you've been diagnosed with prostate cancer, the second-leading cause of cancer death in men. You opt for surgery to remove your prostate. Three months later, a prostate surface antigen (PSA) test shows no prostate cells ...

Multi-talented enzyme—produced on large-scale

Papayas are delicious and healthy – and they contain papain, an enzyme that is isolated from the fruit and used in countless industries. They are used for brewing beer, the handling of meat products, the treating of wool ...

A new glow for electron microscopy

The glowing green molecule known as green fluorescent protein (GFP) has revolutionized molecular biology. When GFP is attached to a particular protein inside a cell, scientists can easily identify and locate it using fluorescence ...

The Black Queen Hypothesis: A new evolutionary theory

Microorganisms can sometimes lose the ability to perform a function that appears to be necessary for their survival, and yet they still somehow manage to endure and multiply. How can this be? The authors of an opinion piece ...
