Scientists find unexpected proteins in bacteria motors

A team of scientists, co-led by Karen Ottemann, a professor of Microbiology and Environmental Toxicology, recently found three unexpected proteins while studying the motors that power the flagella of a species called Helicobacter pylori. The proteins, which are normally found in another type of appendage on a separate group of bacteria, seem to exert control over the motion of the flagella. These proteins, known as PilN, PilO, and PilM, had never been found associated with a flagella before.









Scientists use Hawaiian fossils to study the past and future of climate change

This month, an international team of researchers returned to shore after a two-month-long ocean expedition exploring fossil coral reefs off the coast of Hawai’i. The fossils provide a record of past climate conditions, so scientists are using them to learn about environmental changes throughout geologic history and make predictions about the future
