UI biologist comments on bioelectricity


Bernd Fritzsch, UI professor of biology, comments on the paper of another researcher, the long history of bioelectric batteries, and their potential future use in the human body. Story from: Science


Researchers test whether Red Queen hypothesis makes species resilient

The Red Queen lecturing Alice

Over the years, evolutionary biologists have referenced the “Red Queen” hypothesis, which describes how living organisms, including humans, manage to survive in a changing environment by adapting through sexual reproduction. According to a University of Iowa researcher, the hypothesis is supported. Story

In this video feature Urbandale native Michelle Sullivan talks about her biology major at Iowa, the research opportunities she's had through Honors at Iowa, and how the dance minor complemented her scientific training. Video

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

stylized DNA strand

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
