A growing body of experimental work on how single bacteria sense and respond to their environment has reopened a long-standing question in biology and philosophy: can an individual cell be conscious?

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...

Peroxiredoxins are among the most abundant enzymes involved in managing oxidative stress. They control the levels of peroxides such as hydrogen peroxide, relay redox signals, and help protect other ...

A new LMU study shows how proteins function reliably even without a stable 3D structure—and the crucial importance not only of short sequence motifs, but also of chemical characteristics. Subscribe to ...

In Michigan Tech's biology teaching lab, undergraduate students research potential cancer cures with help from the humble worm.

Salivary glands are essential for everyday human functions —speaking, swallowing, tasting and protecting the mouth—yet they ...

Innate immune sensors—known as pattern recognition receptors (PRRs)—detect specific molecular components of bacterial or ...

Frances Arnold's game-changing technique of "directed evolution" creates enzymes with unusual capabilities. Her own evolution made it possible.

A version of this Priestley Medal address will be presented at the American Chemical Society Spring 2026 meeting ...

Biochemistry has been a core component of Purdue University and the College of Agriculture since 1934. Our graduate students experience a rigorous and creative research environment in which they can ...

"It's exciting to feel like what I'm doing matters. I'm learning so much — not just about chemistry, but about problem-solving, teamwork and communication." When most incoming first-year students were ...
