Green spaces in cities are great, but they don't ensure biodiversity, according to University of Iowa biologists. The team found insect abundance was lacking in two common urban trees, suggesting insect movement may be limited by barriers, such as roads and buildings. Results appear in the journal PLOS ONE.
UI researchers have found a gene in a soil amoeba that can overcompensate for the specific mutations of a similar gene. In humans, those genetic mutations can often lead to tumor growth. Researchers are now looking for a separate human gene that could overcompensate for mutations in the same way.
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.
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.
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.
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.
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.
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.
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.
