Bacteria in ancient flea may be ancestor of the Black Death
About 20 million years ago a single flea became entombed in amber with tiny bacteria attached to it, providing what researchers believe may be the oldest evidence on Earth of a dreaded and historic killer - an ancient strain of the bubonic plague.  View News Article (2015-09-29)

Flower declines shrink bee tongues
Climate-related changes in flower diversity have resulted in a decrease in the length of alpine bumble bees' tongues, a new study reports, leaving these insects poorly suited to feed from and pollinate the deep flowers they were adapted to previously.  View News Article (2015-09-25)

Maternal experience brings an evolutionary advantage
Using a species of butterfly as an example, researchers from the Department of Environmental Sciences at the University of Basel have demonstrated how insects adapt their offspring to changing environmental conditions.  View News Article (2015-09-22)

Naturally occurring 'GM' butterflies produced by gene transfer of wasp-associated viruses
Research teams from the University of Valencia and the University of Tours have discovered that genes originating from parasitic wasps are present in the genomes of many butterflies. View News Article (2015-09-18)

Size matters -- the more DNA the better
A new study from researchers at Uppsala University shows that variation in genome size may be much more important than previously believed. It is clear that, at least sometimes, a large genome is a good genome. View News Article (2015-09-15)

Caterpillar deceives corn plant into lowering defenses against it
In a deception that likely has evolved over thousands of years, a caterpillar that feeds on corn leaves induces the plant to turn off its defenses against insect predators, allowing the caterpillar to eat more and grow faster, according to chemical ecologists in Penn State's College of Agricultural Sciences.  View News Article (2015-09-10)

High rate of Texas bugs carrying Chagas disease
A deadly parasite that causes Chagas disease is widespread in a common Texas insect, according to a new study by University of Texas at El Paso (UTEP) researchers. The finding suggests that the risk of Texans contracting the disease may be higher than previously thought. View News Article (2015-09-10)

Engineers identify how to keep surfaces dry underwater
Imagine staying dry underwater for months. Now Northwestern University engineers have examined a wide variety of surfaces that can do just that -- and, better yet, they know why.  View News Article (2015-08-19)

Mosquito-repelling chemicals identified in traditional sweetgrass
Native North Americans have long adorned themselves and their homes with fragrant sweetgrass (Hierochloe odorata), a native plant used in traditional medicine, to repel biting insects, and mosquitoes in particular. Now, researchers report that they have identified the compounds in sweetgrass that keep these bugs at bay. View News Article (2015-08-17)

Chitin of insects and crustaceans found to be active against pathogenic microorganisms
The study specifically concentrated on chitosan extracted from chitin in the carapaces of insects and crustaceans.  View News Article (2015-08-12)
