Study finds pigeons tend to respond ‘at the edge of chaos’

Researchers found that pigeons tend to decrease variability in their responses when rewarded, but maintain exploratory tendencies and switch among favorite sequences. The study's findings extend beyond evolutionary biology, suggesting adaptability may be beneficial for other complex behaviors like art creation.

Iowa-led research team names, describes new crocodile that hunted iconic Lucy’s species

A new species of crocodile, named Lucy's hunter, was discovered in Ethiopia and found to have hunted the iconic Lucy's species 3 million years ago. The crocodile, named Crocodylus lucivenator, was found to have a prominent lump on its head and a snout that extended further from its nostrils than other crocodiles at that time.

Researchers test new gene treatment to prevent premature skull fusion in newborns

University of Iowa researchers have successfully tested a technique that stimulates a gene to prevent craniosynostosis, a condition causing infants' skulls to close prematurely. The treatment involved injecting nano-sized packets containing the miR-200a gene into newborn mice, allowing their brains to expand and preventing skull fusion.

Researchers find cholesterol-lowering drugs have no effect on kidney function

A study published in the Journal of the American Geriatrics Society found that statin use did not improve kidney function and had no ill effects in older adults. The research provides evidence supporting the kidney safety of statins, suggesting they can be used without concerns related to potential kidney harm.

Study finds physical activity reduces chronic disease risk

A new study by University of Iowa researchers found that physical activity reduces the risk of chronic diseases such as cardiovascular disease, cancer, and diabetes. The study recommends health care providers survey patients on their physical activity levels to identify those at high risk.

Wildfires have erased two decades’ worth of air quality gains in western United States

A new study reveals that wildfires have worsened air quality in the western US, mainly due to increased frequency and ferocity of fires, resulting in a significant increase in premature deaths. The study found black carbon concentrations rose 55% annually in fire-prone areas, contributing to a decline in air quality.

Human brain takes stock of blame

Researchers found that the brain can distinguish between human error and non-error outcomes in as little as 1,000 milliseconds. In cases of human error, the brain takes additional time to catalog the mistake and inform the body to avoid repeating it.

How the brain's immune system worsens epilepsy

Researchers have definitively linked the brain's immune system to worsening epilepsy, identifying a chain of events that causes seizures to worsen. The study suggests repurposing anti-inflammatory compounds and antioxidants could help control epilepsy progression.

New model can detect long-COVID’s effects using simple, 2D chest X-rays

Researchers developed a contrastive learning model that can detect compromised lung function in long-COVID patients from 2D chest X-ray images. The model successfully identified small airways disease and separated it from more advanced respiratory issues, offering an affordable diagnosis option for clinics without CT scanning equipment.

Researchers confirm stress link in the brain

University of Iowa researchers confirmed a neural circuit linking two brain regions that governs how animals react to stressful situations. The study showed that activating this pathway can revive active coping behaviors and reduce stress hormone release in rats.

New study shows flood risk for Iowa farmland

A new study from the University of Iowa has created comprehensive maps showing flood risk for farmland throughout Iowa. The researchers analyzed nearly 25 million acres of agricultural land to classify the flood risk according to eight scenarios, highlighting areas prone to chronic flooding and low productivity yields.

A heart that beats (almost) like our own

Researchers at the University of Iowa found that the fruit fly's head-heart beats much like a human's, driven by an automatic muscle contraction and relaxation. This rhythmic pulsation generates hemolymph flow to the antennae and may help keep the brain clean.

Physicists report definitive evidence how auroras are created

Researchers have identified Alfven waves as the primary cause of the most brilliant auroras. These waves accelerate electrons toward Earth, producing atmospheric light show, through a process known as Landau damping. The study, conducted at the Large Plasma Device, confirms decades-long quest to demonstrate experimentally the physical ...

Physicists describe new type of aurora

Researchers have found a new feature in the diffuse aurora, where sections of the background-like glow disappear and then reappear after a short period. This phenomenon, dubbed 'diffuse auroral erasers,' has never been mentioned in scientific literature and raises questions about its frequency and potential impact on Earth's climate.
