A team of U.S. scientists has discovered the oldest directly dated ice and air on the planet in the Allan Hills region of East Antarctica.

Pseudomonas aeruginosa is a species of bacteria that, when organized on a surface to form a community known as a biofilm, causes lethal infections in cystic fibrosis patients and resists treatment with antibiotics.

A UCLA-led research team has uncovered a key mechanism controlling initial biofilm formation in Pseudomonas, in which cells sense and follow sugar-based trails secreted by other bacteria to organize themselves into a colony on a surface.

This discovery could lead to treatments for deadly infections in people with cystic fibrosis and in hospitalized patients on ventilators, as well as solutions for problems in industry that are rooted in the presence of bacterial biofilms.

Research uses low-cost, light-weight earthquake-monitoring tools to measure how towering cacti resonate in response to wind and ground motion. University of Utah geologist Jeff Moore unlocks the dynamic properties and structural properties of saguaro without harming them. 

What do honey bees and electric power grids have in common? More than you might think, according to Wangda Zuo, professor of architectural engineering at Penn State. Zuo is leading a new project funded by a $1 million award from the U.S. National Science Foundation (NSF) to investigate how coordinating and controlling distributed energy resources — similar to how honey bees regulate their colony’s resources — may help improve the distribution resiliency of electric grids.
