Biofilm Streamers Clog Medical Devices

Bacterial communities called biofilms can quickly clog medical devices such as stents and catheters by forming 3-dimensional streamers that block flow. The finding will inform future approaches to prevent these deadly clogs.

Compound Induces Antitumor Protein

Researchers identified a small compound that can boost production of a known tumor-suppressing protein. The finding may improve on current approaches—now in clinical trials—that target this biological pathway.
