Best offense is a great defense for some carnivorous plants

Insect-eating plants have fascinated biologists for more than a century, but how plants evolved the ability to capture and consume live prey has largely remained a mystery. Biologist Ivan Radin in Arts & Sciences and collaborators investigated the molecular basis of plant carnivory in sundews and found evidence that it evolved from mechanisms plants use to defend themselves.

Earth’s deep mantle was drier from the start

Geoscientist Rita Parai in Arts & Sciences uses noble gas isotopes to better understand the formation and evolution of planetary bodies. Her new modeling study published in PNAS shows that the deep mantle had low concentrations of volatiles like xenon and water when it formed, setting up an internal viscosity contrast with lasting impacts.

Endangered species need help: No biology expertise required

New approaches to help save animals from extinction may come from experts outside of the traditional natural science disciplines. The Living Earth Collaborative invites social scientists, political scientists, engineers and other experts from the university community who would like to be involved in efforts to help with conservation projects to participate in a July 21 social event.
Urban bees collaboration wins USDA grant

Urban bees collaboration wins USDA grant

A team that received early support from the Living Earth Collaborative was awarded a $633,000 grant from the U.S. Department of Agriculture to evaluate pollination in orchards across the city of St. Louis. They will examine how factors such as human population density, socioeconomic status, soil type and surrounding vegetation impact insect numbers and fruit yield.
