A major compound in soil organic matter degrades chronic wasting disease prions and decreases infectivity in mice, according to a study published November 29 in the open-access journal PLOS Pathogens by Judd Aiken of the University of Alberta, and colleagues.
Chronic wasting disease is an environmentally transmissible, fatal prion disease affecting free-ranging deer, moose, elk and...
Rivaling the evolution of feathers in dinosaurs, one of the most extraordinary transformations in the history of life was the evolution of baleen -- rows of flexible hair-like plates that blue whales, humpbacks and other marine mammals use to filter relatively tiny prey from gulps of ocean water. The unusual structure enables the world's largest...
Tyrone Lavery, postdoctoral researcher at the Field Museum in Chicago, traveled nearly 8,000 miles to find two species -- a giant rat and a monkey-faced bat -- in Malaita, one of the Solomon Islands' largest provinces.
The search for these mammals isn't over yet -- but in partnership with the Kwaio, an indigenous people in Malaita,...
Some lizards in the eastern U.S. have adapted to invasive fire ants -- which can bite, sting, and kill lizards -- reversing geographical trends in behavioral and physical traits used to avoid predators. A new study describing this reversal appears online on November 29, 2018, in the journal Global Change Biology and reveals that new...
Blue whales around the world are singing a little flat, and scientists may now have more clues as to the reason why.
A new study finds there's a seasonal variation in the whales' pitch correlated with breaking sea ice in the southern Indian Ocean. The new research also extends the mysterious long-term falling pitch to related...

Researchers from Lincoln Park Zoo's Urban Wildlife Institute and Davee Center for Epidemiology and Endocrinology set out to understand why. The findings are published Nov. 28 in Frontiers in Ecology and Evolution.
Rats are a unique species...
