Research at Iowa State University has led scientists to uncover how the deadly Zaire Ebola virus decoys cells and eventually kills them. A research team led by Gaya Amarasinghe, an assistant professor of biochemistry, biophysics and molecular biology, had previously solved the structure of a critical part of an Ebola protein known as VP35, which is involved in host immune suppression. Amarasinghe and his research team now know how VP35 is able to do it. When most viruses invade a cell, they...

Three Iowa State University physicists who took winter trips to the Large Hadron Collider for meetings and experimental work are starting to see real data from the planet's biggest science experiment. Finally. The multibillion-dollar collider made international news on Sept. 10, 2008, when it sent its first beam of protons around 17 miles of underground tunnel near Geneva, Switzerland. But breakdowns in the machine's high-current electrical connections forced a complete shutdown for more than...

A spear-shaped hunting tool used by savanna chimpanzees in Senegal and provided by Iowa State University Associate Professor of Anthropology Jill Pruetz will be displayed in a new exhibition hall opening next year at the Smithsonian's National Museum of History. The exhibit is dedicated to the discovery and understanding of human origins. The spear will be displayed in a case that highlights two other original tools made by chimpanzees: a stone anvil and hammerstone with oil palm nuts, and an...

The use and control of fire are behavioral characteristics that distinguish humans from other animals. Now, a new study by Iowa State University anthropologist Jill Pruetz reports that savanna chimpanzees in Senegal have a near human understanding of wildfires and change their behavior in anticipation of the fire's movement. An ISU associate professor of anthropology, Pruetz and Thomas LaDuke, an associate professor of biological sciences at East Stroudsburg (Pa.) University, co-authored the...

A researcher at Iowa State University has discovered how a group of proteins from plant pathogenic bacteria interact with DNA in the plant cell, opening up the possibility for what the scientist calls a "cascade of advances." Adam Bogdanove, associate professor in plant pathology, was researching the molecular basis of bacterial diseases of rice when he and Matthew Moscou, a student in the bioinformatics and computation biology graduate program, discovered that the so-called TAL effector...

Neal Iverson opened his laboratory's walk-in freezer and said the one-of-a-kind machine inside could help scientists understand how glaciers slide across their beds. And that could help researchers predict how glaciers will react to climate change and contribute to rising sea levels. Iverson is an Iowa State University professor of geological and atmospheric sciences. He's worked for three years on his big new machine, which is over nine feet tall, that he calls a glacier sliding simulator....

Researchers at Iowa State University have found an essential key to possibly cure Parkinson's disease and are looking for others. Anumantha Kanthasamy, a distinguished professor of biomedical sciences and 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 and thinks he has found hope for the cure. Parkinson's disease sufferers lack a sufficient...

Researchers at Iowa State University have identified an enzyme that helps make tuberculosis resistant to a human's natural defense system. Researchers have also found a method to possibly neutralize that enzyme, which may someday lead to a cure for tuberculosis. Tuberculosis is caused by Mycobacterium tuberculosis and is a contagious disease that is on the rise, killing 1.5 to 2 million people worldwide annually. Reuben Peters, associate professor in the department of biochemistry, biophysics...

A new Iowa State University study found that a family, school and community intervention program helps children live healthier lives and could be a new tool in the fight against the nation's childhood obesity epidemic. In the study, children who participated in The Switch® program -- a program developed by the Minneapolis-based National Institute on Media and the Family (NIMF) -- watched an average of two fewer hours of television and also consumed two more servings of...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
