A new study revealed molecular features linked to more aggressive prostate cancer in a subset of patients who had been classified as low risk, highlighting biological differences that may not be apparent from clinical measures alone. The results could lead to new therapeutic strategies.

Nanotechnology using plant-based fibers could be the answer to detecting and cleaning up pesticides, fertilizers and other chemicals before they become harmful on the farm and in the environment.

A University of Tennessee Institute of Agriculture research project led by Mi Li, associate professor in the Center for Renewable Carbon and the School of Natural Resources, received $300,000 for two years from the USDA National Institute of Food and Agriculture’s Agriculture and Food Research Initiative nanotechnology program to create these prototype materials. The project also includes researchers from the University of Memphis and Auburn University.

A landmark survey of the world’s largest free-roaming giant tortoise population has revealed the once endangered species is thriving and stable in the Seychelles. Giant tortoises found on the Aldabra Atoll - one of two population centres in the world - are now numbered at around 180,000 individuals following five years of surveying and the use of sophisticated statistical techniques.
