Researchers track down cause of eye mobility disorder

The image depicts mice having a normal nerve (left) as compared to an incomplete nerve, a condition resulting in permanent downward gaze in both mice and humans.

In a paper published in the April 16 print issue of the journal Neuron, UI researchers Bernd Fritzsch and Jeremy Duncan and their colleagues at Harvard Medical School, along with investigator and corresponding author Elizabeth Engle, describe how their studies on mutated mice mimic human mutations responsible for an eye mobility disorder.

More to biological diversity than meets the eye

Female fly on a flower

UI biology researcher Andrew Forbes and his colleagues studied fly and wasp species on plants in a Chilean rainforest and found more species than biological theory would have predicted because specialized interactions between species allow a larger, more diverse number of species to live in the same place.

World's oldest rocks spark discussion on origin of life

boninites (rock)

An Australian-led team including a UI geologist studied rocks from the coast of Hudson Bay in Quebec, Canada and found indications that life existed on Earth nearly 900 million years early than currently thought. Story

A quicker, cheaper way to detect staph in the body

Watch out, infection. University of Iowa researchers have created a probe that can identify staph bacteria before symptoms appear. The probe is noninvasive and is expected to be cheaper and faster than current diagnostic techniques. Results published in the journal Nature Medicine. Story

The science of evolution

Today the overwhelming majority of scientists in Iowa, the United States, and across the world agree that biological evolution explains the diversity of life on our planet. Story

The developmental genetics of space and time

Understanding the concept of morphogen gradients—the mechanism by which a signal from one part of a developing embryo can influence the location and other variables of surrounding cells—is important to developmental biology, gene regulation, evolution, and human health. Story

Project HOPE helps students explore the health sciences

students look at a human muscle skeleton model

Employment opportunities in the health science fields will be the topic of discussion when students from two eastern Iowa middle schools visit the University of Iowa Department of Biology this spring as part of Project HOPE, created by College of Education associate professor Saba Ali. Story

UI researcher learns mechanism of hearing is similar to car battery

 A fruit fly auditory organ

University of Iowa biologists have advanced their knowledge of human hearing by studying a similar auditory system in fruit flies—and by making use of the fruit fly “love song.” Results featured on the cover of the journal Proceedings of the National Academy of Sciences. Story

Biology research may lead to new insight into stem cell division and tumor formation

Bryan Phillips, an assistant professor in the University of Iowa College of Liberal Arts and Sciences Department of Biology, was recently awarded a three-year grant by the Roy J. Carver Charitable Trust in the amount of $372,828. Research funded by the grant could lead to the development of drugs to alleviate the effects of human disease. Story

Biology prof elected to Academia Sinica

Chun-Fang Wu, professor of biology in the University of Iowa College of Liberal Arts and Sciences, was elected as a prestigious academician of Academia Sinica, the most preeminent academic institution in Taiwan. Story
