A new study offers hope for children born with a rare genetic disease, according to a paper published by the American Association for the Advancement of Science. The research was led by Dr. Matthew Ellinwood, a veterinarian and animal science professor at Iowa State University, in collaboration with Dr. Patricia Dickson at the Harbor-UCLA Medical Center, with colleagues at the Iowa State College of Veterinary Medicine, the University of Tennessee, St. Louis University and the University of...

Patricia Thiel of Iowa State University and the Ames Laboratory put a box of tissues to the right, a stack of coasters to the middle and a trinket box to the left. "Nature," she said of her table-top illustration, "doesn't want lots of little things." So Thiel grabbed the smaller things and slid them into a single pile next to the bigger tissue box. "Nature wants one big thing all together, like this." Thiel, an Iowa State Distinguished Professor of Chemistry and a faculty scientist for the...

The flu virus uses a shuttle mechanism to relay protons through a channel in a process necessary for the virus to infect a host cell, according to a research project led by Mei Hong of Iowa State University and the Ames Laboratory. The findings are published in the Oct. 22 issue of the journal Science. Hong, an Iowa State professor of chemistry and an associate of the U.S. Department of Energy's Ames Laboratory, said her research team used solid-state nuclear magnetic resonance (NMR)...

The nation's poverty rate climbed to 14.3 percent -- the highest level since 1994 -- according to the Census Bureau's annual report on the economic well-being of U.S. households. That means one in seven Americans now live in poverty, and that may have an especially depressing effect on people living in bad neighborhoods, according to two Iowa State University researchers. Daniel Russell, an Iowa State professor of human development and family studies; and Carolyn Cutrona, professor and chair...

A research team led by Edward Yu of Iowa State University and the Ames Laboratory has discovered the crystal structures of pumps that remove heavy metal toxins from bacteria, making them resistant to antibiotics. The findings are published in the Sept. 23 issue of the journal Nature. Yu - an Iowa State associate professor of chemistry, of physics and astronomy, of biochemistry, biophysics and molecular biology and an associate of the U.S. Department of Energy's Ames Laboratory - said the...

A cow's eyes may show signs of neurological disorders such as mad cow disease, according to scientists.Noticing the signs early enough may help prevent infected meat from reaching the food supply.Researchers at the Iowa State University examined the retinas of sheep infected with scrapie -- a disease similar to mad cow disease. The researchers stated in the journal Analytical Chemistry that the sick sheep's eyes had a unique "glow."People who eat contaminated meat may contract a brain-wasting...

A new Iowa State University study has found that corn bred to contain increased levels of beta-carotene is a good source of vitamin A. The discovery gives added support to the promise of biofortified corn being developed through conventional plant breeding as an effective tool to combat vitamin A deficiency in developing countries. Beta-carotene is converted in the body to vitamin A. The researchers found that the beta-carotene in the corn was converted to vitamin A at a higher rate than...

Iowa State University researchers have found a way to produce high-value chemicals such as ethylene glycol and propylene glycol from biomass rather than petroleum sources. Walter Trahanovsky, an Iowa State professor of chemistry who likes to write out the chemical structures of compounds when he talks about his science, was looking to produce sugar derivatives from cellulose and other forms of biomass using high-temperature chemistry. And so he and members of his research group studied the...

An Iowa State University team of researchers has developed a type of hybrid proteins that can make double-strand DNA breaks at specific sites in living cells, possibly leading to better gene replacement and gene editing therapies. Bing Yang, assistant professor of genetics, development and cell biology, and his colleagues developed the hybrid protein by joining parts of two different bacterial proteins. One is called a TAL effector, which functions to find the specific site on the gene that...

By planting switchgrass and using certain agronomic practices, farmers can significantly reduce the amount of nitrogen and nitrates that leach into the soil, according to Iowa State University research.Matt Helmers, associate professor of agricultural and biosystems engineering, and Antonio Mallarino, professor of agronomy, have been studying the amount of nitrates that pass through soil into tiling systems from several different types of crops and fertilizer treatments for the past three...
