The worlds largest insect emergence of "Brood X" cicadas in May will result in some damage to fruit trees and prized yard trees and shrubs, but the large insects will not cause crippling harm to common farm crops, an Indiana University scientist says.
Two cicadas mate during their brief above-ground reproductive period.

"There will be some crop damage, especially to orchards, but we dont expect a disaster," said IU Bloomington biologist Keith Clay, who recently received a three-year, $300,000 National Science Foundation grant to study Brood X. "The cicadas dont harm evergreen trees or leafy, non-woody plants. But isolated shrubs, broad-leafed trees, and trees with soft, woody branches are vulnerable. People who have just spent thousands of dollars on landscaping may want to consider throwing netting over the trees during the two-to-three-week period when the adult cicadas are out."
Clay recommends that concerned gardeners, vintners and farmers place netting -- with holes no greater than one-half inch across -- securely over the top of vulnerable plants.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
