Insights into Toxoplasma gondii parasites - MMP 16

Written by

Emma H. Wilson of the University of California, Riverside, talks with Jeff Fox about efforts, with her collaborators to determine more precisely how Toxoplasma gondii parasites disrupt the mammalian brain—in this case, the brains of mice.

Carolyn Shore of Pew Charitable Trusts in Washington, D.C., and Ruben Tommasi of Entasis Therapeutics in Waltham, Massachusetts, talk with Jeff Fox about what’s needed to identify and develop new antimicrobial agents to treat infections caused by bacterial pathogens, with an emphasis on gram-negative bacterial pathogens.

A look at several microorganisms involved with electricity and bacterial proteins called nanowires and mineral composites made by fungi that might be used as capacitors with Gemma Reguera and Geoffrey Gadd.

Redetermining the ratio of microbial to human cells. Widely cited as 10 to 1, the real ratio is closer to even.

Jon Telling of Bristol University in Bristol, United Kingdom talks with Jeff Fox about his findings suggesting that the grinding of glaciers over rocks can liberate hydrogen, which, in turn, drives the growth of methanogens within microbial ecosystems.

Øjvind Moestrup and Peter Ulvskov, both at the University of Copenhagen and Jesper Harholt at Carlsberg Laboratory, also in Copenhagen, Denmark, talk with Jeff Fox about their hypothesis about terrestrial plants, based on analyses of the cell walls of charophycean green algae.

Lewis and Krithivasan Sankaranarayanan—“Krithi”-- both from the University of Oklahoma in Norman talk with Jeff Fox about their analyses of the gut microbiomes of American Indians of Cheyenne and Arapaho ancestry.

Lu, an Associate Professor of Biological Engineering and Electrical Engineering and Computer Science at Massachusetts Institute of Technology in Cambridge, Massachusetts, talks with Jeff Fox about efforts to develop new phage varieties, swapping in phage tail genes that enable them to target specific bacterial pathogens, including those carrying virulence or antibiotic resistance factors.

Mertens, a graduate student working with Kevin Verstrepen at the University of Leuven in Belgium, talks with Jeff Fox about their efforts to develop new yeast strains for making lager beers—imparting novel flavor and aroma notes without detracting from the freshness and drinkability of lagers.
