Luckily for us, the economically devastating Karnal bunt fungus needs personal ads and singles bars more than we do.
Airborne spores from the fungus, which damages wheat crops, are limited in how well they can start new infections over long distances, according to the findings from a Kansas State University project.
A phenomenon known as the Allee effect occurs when a small population of a species spread over a large area has little success in reproduction. The reason is that when individuals are dispersed over a wide area, it becomes difficult to find a mate. Like male and female humans, each Karnal bunt spore has something similar to a gender, and must find a spore with a different gender to reproduce. Karnal bunt has a larger spore that can reproduce on its own, but is heavier and less likely to be blown over long distances. It is the bunts lighter, airborne spore that needs a mate.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
