Dragonfly migration resembles that of birds, scientists say
Scientists have discovered that migrating dragonfliesand songbirds exhibit many of the same behaviors, suggesting the rulesthat govern such long-distance travel may be simpler and more ancientthan was once thought. The research, published in the May 11 Biology Letters, is based on datagenerated by tracking 14 green darner dragonflies with radiotransmitters weighing only 300 milligrams -- a...Dragonfly's metabolic disease provides clues about human obesity
Parasite-infected dragonflies suffer the same metabolic disorders that have led to an epidemic of obesity and type-2 diabetes in humans, reveal the findings of research conducted at Penn State University that are due to be published in the 5 December 2006 issue of the Proceedings of the National Academy of Science and also in the PNAS early online edition at www.pnas...Dragonfly’s metabolic disorders help explain Human Obesit
Researchers from Penn State University have unearthed clues,from studies on dragonflies, that may help in understanding obesity in humans.// The study has revealed that when dragonflies are infected with certain parasites they suffer from metabolic disorders. These disorders are very similar to the Type -2 diabetes seen in humans. Obesity is frequently seen associated with diabetes. The...
