When your family members gather at a picnic in your backyard, there may be 10 to 20 people -- maybe more -- enjoying your barbecue. When flies visit your party, be glad they don't bring their entire family. Houseflies have more than 152,000 cousins. And those are just the ones we know about. An Iowa State University researcher is one of a team of scientists who have recently researched the fly family tree -- one of the most complicated in the animal world. "It really isn't a tree, it's sort...

Solving problems for clients in any field usually requires gathering information and creative thinking that leads to practical and inventive solutions. A new computer interface developed at Iowa State University is helping students use what they've learned in the horticulture classroom and apply it to problems they'll face when they are on the job site. The project, called ThinkSpace, is led by a group of ISU faculty including Ann Marie VanDerZanden, professor of horticulture and associate...

NASA's Kepler Mission has detected changes in brightness in 500 sun-like stars, giving astronomers a much better idea about the nature and evolution of the stars.Prior to Kepler's launch in March 2009, astronomers had identified the changes in brightness, or oscillations, of about 25 stars similar to our sun in size, age, composition and location within the Milky Way galaxy.The discoveries are reported in a paper, "Ensemble Asteroseismology of Solar-Type Stars with the NASA Kepler Mission,"...

NASA's Kepler Mission is giving astronomers such a clear view of changes in star brightness that they can now see clues about what's happening inside red giant stars. "No one anticipated seeing this before the mission launched," said Steve Kawaler, an Iowa State University professor of physics and astronomy and a leader of the Kepler Asteroseismic Investigation. "That we could see so clearly down below a red giant star's surface was unexpected." The astronomers' preliminary findings are...

An increase in average wind speeds blowing over the world's oceans over the past quarter-century have generated higher waves and rougher seas, and researchers said those increased wind speeds could lead to more water vapor in the air, providing added moisture for rain and potentially increasing rainfall. In a study published online in the journal Science on Thursday, researchers led by Ian Young of Swinburne University of Technology in Australia said the increased wind speed averages could...

Sixty million dollars are being invested by the federal government on three major studies on the effects of climate change on crops and forests in hopes of ensuring farmers and foresters can continue producing food and timber while limiting the impact of a shifting environment, the Associated Press (AP) reports. Midwestern corn will be the subject of one study, wheat will be the focus in the Northwest and a third study will determine the effects on Southern pine forests. The studies will...

Invasive plant species have long had a reputation as being bad for a new ecosystem when they are introduced. Stan Harpole, assistant professor of ecology, evolution and organismal biology at Iowa State University, is founding organizer of a team of more than 70 researchers working at 65 sites worldwide that tested that assumption. They wanted to know if it is true that problematic invasive species often spread widely in their new habitats because they don't encounter predators or diseases...

A protein pathway that may hold the secret to understanding Parkinson's disease has been discovered and explained by Iowa State University researchers. Anumantha Kanthasamy, a distinguished professor of biomedical sciences and the W. Eugene and Linda R. Lloyd Endowed Chair in Neurotoxicology at the ISU College of Veterinary Medicine, has been working to understand the complex mechanisms of the disease for more than a decade. He believes this recent discovery offers hope for the cure. The...

A research team led by Edward Yu of Iowa State University and the Ames Laboratory has identified and described two parts of the three-part system that pumps toxins from bacteria and allows them to resist antibiotics. The discoveries are published in the Feb. 24 issue of the journal Nature. The paper describes the co-crystal structure of two parts of the three-part efflux pump that recognizes and removes heavy metal toxins from bacteria. A research team led by Yu "“ an Iowa State...
