The western corn rootworm continues to be on the rise in Europe. Why attempts to biologically target this crop pest by applying entomopathogenic nematodes have failed, can now be explained by the amazing defense strategy of this insect. In their new study, scientists from the University of Bern, Switzerland, and the Max Planck Institute for Chemical Ecology in Jena, Germany, show that the rootworm larvae are able to sequester plant defense compounds from maize roots in a non-toxic form and can activate the toxins whenever they need them to protect themselves against their own enemies.

Dark Ocean Bacteria Discovered to Play Large Role in Carbon Capture
Marine bacteria that live in the dark depths of the ocean play a newly discovered and significant role in the global carbon cycle, according to a new study published in Science.
Fear of Sharks Influences Seaweed Growth on Fijian Coral Reefs
Fishes’ fear of sharks helps shape shallow reef habitats in the Pacific, according to new research by a scientist at Bigelow Laboratory for Ocean Sciences.
Breakthrough in tornado short-term forecasting could mean earlier, more accurate warnings
When mere seconds of storm warning could mean the difference between harm or safety, two researchers with Western University ties have developed a tornado-prediction method they say could buy as much as 20 minutes more warning time.
The health threat from mercury in freshwater fish could be blowing away in the wind
Mercury is one of the top 10 chemical concerns for public health according to the World Health Organization (WHO). In more than half of Swedish lakes the mercury levels are so high that eating the fish is a threat to the health of people and wildlife. To make matters worse, the problem seems to have no solution in sight. But new research gives hope: the mercury problem could very well be blowing away in the wind.
SMU seismology research shows North Texas earthquakes occurring on “dead” faults
Study by Beatrice Magnani, USGS and other SMU scientists shows recent seismicity in Fort Worth Basin occurred on faults not active for 300 million years.
