A team of scientists has discovered that descendants of "exploratory" butterflies that colonized new habitats differ genetically from their more cautious cousins. The team, led by James Marden, a professor of biology at Penn State University, and Christopher Wheat, a post-doctoral scholar working at both Penn State and the University of Helsinki, has revealed some of the genetic bases for faster egg maturation, a higher rate of energy metabolism, and superior flight ability -- traits that...

"You don't have to go out into the woods anymore," says tick expert Brian F. Allan, PhD, who just completed a postdoctoral appointment at Washington University in St. Louis. "The deer are bringing tick-borne disease to us." So, it stands to reason that anything deer like, might increase the risk of tick-borne disease for people. The invasive plant bush honeysuckle, for example. Yes, that leafy shrub with the lovely egg-shaped leaves on arching branches, fragrant white or yellow flowers and...

New research shows that when some fence lizards are attacked by fire ants they "stress out"-- a response that actually helps the species to survive by heightening the animal's awareness of imminent danger. Tracy Langkilde, assistant professor of biology at Penn State University, found that lizards living in areas of the southeastern United States, where large numbers of fire ants also live, have elevated levels of stress hormones, called glucocorticoids. The stress-hormone study comes on the...

New research points to a genetic route to understanding and treating epilepsy. Timothy Jegla, an assistant professor of biology at Penn State University, has identified an ancient gene family that plays a role in regulating the excitability of nerves within the brain. "In healthy people, nerves do not fire excessively in response to small stimuli. This function allows us to focus on what really matters. Nerve cells maintain a threshold between rest and excitement, and a stimulus has to cross...

UC Riverside biologists say young male crickets grow larger in the presence of sexually mature adult male crickets In the animal kingdom, sexual signals often are manifested as displays of bright coloration or, in the case of crickets, as loud song. Adult male crickets produce loud song to attract females, but the song, which permeates the environment, can be overheard also by unintended receivers - such as young males unable to produce song due to a mutation they carry. Until now researchers...

Mercury levels in fish are prompting widespread consumption advisories and uncertainty among consumers over which species are safe to eat. Now researchers at North Carolina State University have developed a model that will help scientists and regulators around the country predict which areas are likely to have fish with high mercury levels "“ a breakthrough that should help officials address public uncertainty by developing health advisories for specific water bodies and fish species....


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
