Bacteria created using mirror images of natural biomolecules would pose a grave threat to life on Earth, some researchers ...

For biologists, seeing is believing. But sometimes biologists have a hard time seeing. One particularly vexing challenge is seeing all the molecules in an intact tissue sample, down to the level of ...

Biomolecules, also known as organic molecules, include sugars, proteins and lipids and are the building blocks of all life.

When we think about highly sensitive medical testing, we often imagine a hospital laboratory filled with large instruments, trained technicians, and carefully controlled conditions. This is especially ...

What’s in our food? Believe it or not, we still don’t know. We don’t have reliable indexes of the biomolecules in an overwhelming majority of what we eat, a team of global scientists say—which is ...

A new tissue expansion method enables scientists to use mass spectrometry imaging to simultaneously detect hundreds of molecules at the single cell level in their native locations. For biologists, ...
