Dinosaur Bones Reveal Ancient Bug Bites Paleontologists have long been perplexed by dinosaur fossils with missing pieces -- sets of teeth without a jaw bone, bones that are pitted and grooved, even bones that are half gone.
Bees Disease: One Step Closer To A Cure Scientists in Germany have discovered a new mechanism of infection for the most fatal bee disease. American Foulbrood is the only infectious disease which can kill entire colonies of bees. Every
A First: Researchers Apply Efficient Coding Principle To Sense Of Smell For the first time, researchers have demonstrated that the efficient coding principle regarding neurobiological processes applies to sense of smell. The team displays this quantitative relationship in a study of male
Pathway Found That Lets Mosquitoes Fatten Up, Slow Down For Winter Two genes that help insulin regulate mosquitoes' growth have been identified as key contributors to how the insects enter a dormant state to survive winter's cold. The research finding broadens the
Insects Use Plants Like A Telephone Ecologists have discovered that subterranean and aboveground herbivorous insects can communicate with each other by using plants as telephones. Subterranean insects issue chemical warning signals via the leaves of the plant.
Fly Is At Home On A Crab, With New Evolutionary Neighbors Scientists have rediscovered a fly living in the mouth of land crabs. One of the more bizarre choices of breeding substrates comes from Drosophila endobranchia. This species is one out of
Fungus Fight: Researchers Battle Against Dangerous Corn Toxin The spiraling use of corn for food and fuel is creating heightened concerns about contamination of this staple crop with deadly aflatoxin. Produced by certain fungi that grow on corn, this
Flowers' Fragrance Diminished By Air Pollution, Study Indicates Air pollution from power plants and automobiles is destroying the fragrance of flowers and thereby inhibiting the ability of pollinating insects to follow scent trails to their source, a new study
Playing Dead Works For Young FIre Ants Under Attack Pretending to be dead is an effective self-defense strategy adopted by young fire ant workers under attack from neighboring colonies. This tactic makes them four times more likely to survive aggression
Double Trouble With Insecticide-resistant Mosquitoes Geneticists discover that insecticide resistance genes work together in mosquitoes, increasing their survival rate with important consequences for pest management. Mosquitoes harboring two insecticide-resistance genes have been found to survive unexpectedly
Creating Homes That Please America's Wild Bees Just like people who are looking for a perfect place to live, some female bees search for the ideal place to build their nests. Entomologists are discovering more about the "nesting
High-flying Moths Don't Just Go With The Flow Enormous numbers of migratory moths that fly high above our heads throughout the night aren't at the mercy of the winds that propel them toward their final destinations. Rather, they rely
Bats Play A Major Role In Plant Protection If you get a chance to sip some shade-grown Mexican organic coffee, please pause a moment to thank the bats that helped make it possible. At Mexican organic coffee plantations, where
