When stubborn bugs refuse to make drugs

Streptomyces
Research published in the Proceedings of the National Academy of Sciences by biologist Joshua Blodgett in Arts & Sciences highlights comparative metabologenomics as a powerful approach to expose the features that differentiate strong antibiotic producers from weaker ones.

Depth of perception

Moss
Minuscule tunnels through the cell membrane help cells to perceive and respond to mechanical forces, such as pressure or touch. A new study led by biologists in Arts & Sciences directly investigates what PIEZO channels are doing in the tip-growing cells in moss and pollen tubes of flowering plants, and how.

Two strands are tougher than one

Illustration of double-stranded RNA
Research from the lab of Kimberly Parker at the McKelvey School of Engineering reveals key differences between single- and double-stranded RNA, insights that may prove useful to fields from agriculture to medicine.

Moeller wins Heyrovsky Prize for electrochemistry

Moeller
Kevin Moeller, professor of chemistry in Arts & Sciences, won the 2021 Jaroslav Heyrovsky Prize for Molecular Electrochemistry from the International Society of Electrochemistry. His research focuses on using electrochemistry as a synthetic tool for constructing everything from complex organic molecules to two-dimensional addressable surfaces.
