Surface protein editing in bacteria

University of Minnesota researchers have discovered this previously unknown signaling pathway that regulates surface proteins on bacteria that can lead to new targets for antibiotics.

The sticky science of underwater adhesives

Mussels stick to rocks on the seafloor, to aquatic plants, and—to the consternation of boaters—they can hitch rides fastened to seafaring vessels no matter their composition: metals, rubber, glass, wood and more.

Slug glue reveals clues for making better medical adhesives

The Dusky Arion slug produces a defensive glue that fouls the mouthparts of any would-be predator. Two new studies reveal more about how this glue achieves its strong sticking power and flexibility, insights that could be ...

Mussel-inspired coatings for drug delivery

Nature is full of wonderful, time-tested solutions to different challenges. Science has turned its attention to reproducing and repurposing these phenomena to create more sustainable responses to human challenges. This relatively ...

Team gets a closer look at how proteins meet on the cell membrane

Scripps Research scientists have uncovered the workings of a critical process in cell survival. Their study, published recently in the Proceedings of the National Academy of Sciences, is the first to show exactly how a protein ...

Bacterial adhesion in vitro and in silico

Ludwig-Maximilians-Universitaet (LMU) researchers in Munich, Germany, have characterized the physical mechanism that enables a widespread bacterial pathogen to adhere to the tissues of its human host.

Slippery liquid surfaces confuse mussels

It all began with a bet at a conference in Italy in 2013. Nicolas Vogel, Ph.D., then a postdoctoral fellow in Joanna Aizenberg's lab at the Wyss Institute for Biologically Inspired Engineering at Harvard University and Harvard's ...

Nontoxic underwater adhesive could bring new surgical glue

A nontoxic glue modeled after adhesive proteins produced by mussels and other creatures has been found to out-perform commercially available products, pointing toward potential surgical glues to replace sutures and staples.
