Engineers model mutations causing drug resistance
Whether it is a drug-resistant strain of bacteria, or cancer cells that no longer react to the drugs intended to kill them, diverse mutations make cells resistant to chemicals, and "second generation" approaches are needed. Now, a team of Penn State engineers may have a way to predict which mutations will occur in people, creating an easier path to create effective pharmaceuticals.

Developing a novel oral antibiotic to treat multidrug-resistant gonorrhea
Up to $2.86M has been awarded to a research team including Penn State scientists to develop a new oral antibiotic to treat multidrug-resistant gonorrhea, a sexually transmitted disease caused by bacteria that have developed resistance to all but one existing antibiotic.

Gene regulatory factors enable bacteria to kill rivals and establish symbiosis
Two factors that control the expression of a key gene required by luminescent bacteria to kill competing bacterial cells have been identified. The finding, by researchers at Penn State, sheds light on the molecular mechanisms that enable different strains of bacteria to compete and establish symbiosis in the Hawaiian bobtail squid.

Listening to your gut: A powerful new tool on the microbiome and cell metabolism
Many aspects of our lives — not only the presence or absence of certain diseases, but conditions like obesity, sleep patterns, even mood — may be determined, to a surprising extent, by the microbes living inside of us.

Herringbone pattern in plant cell walls critical to cell growth
Plant cells tend to grow longer instead of wider due to the alignment of the many layers of cellulose that make up their cell walls, according to a new study that may have implications for biofuels research.

Persistent environmental contaminant changes the gut microbiome of mice
An industrial chemical — phased out since 2002, but previously used in stain and water-repellent products and firefighting foam — alters the gut microbiome of mice and could have implications for human health, according to an international team of researchers.
