Study finds Midwest flooding more frequent

Researchers from the University of Iowa analyzed daily stream gauge records from 1962-2011 and found that 34% of stations experienced an increase in flood frequency, while 9% saw a decrease. The study suggests that warmer temperatures and increased rainfall are contributing to the rising number of big floods in the region.

UI researchers link smoke from fires to tornado intensity

Researchers found that smoke from spring fires in Central America intensified conditions leading to severe tornadoes in the US. The study's results suggest a novel mechanism by which smoke affects tornado severity, and highlight the importance of considering atmospheric particles in weather prediction models.

Cookie Monster teaches self-control

A study by University of Iowa professor Deborah Linebarger found that preschoolers who watched videos starring Cookie Monster were better able to control impulses and remember number sequences. These executive functioning skills are crucial for school readiness and predict academic skills like reading, math, and science.

Green spaces don't ensure biodiversity in urban areas

A University of Iowa study found that planting trees in urban areas does not guarantee an increase in insect populations, despite attracting species. The researchers surveyed tree species and insect abundance, concluding that built environments can limit diversity by impeding insects' ability to interact with other trees.

Sleep twitches light up the brain

A University of Iowa study found that sleep twitches activate the brains of mammals differently than movements made while awake. Twitches during rapid eye movement (REM) sleep comprise a different class of movement and provide evidence that sleep twitches teach newborns about their limbs.

Parents, listen next time your baby babbles

Parents who engage with their infant's babbling can accelerate their child's vocalizing and language learning, according to a new University of Iowa study. Infants whose mothers responded to their babbling showed an increase in developmentally advanced vocalizations and began directing more of their babbling towards their mothers.

A map for eye disease

Researchers have created a high-resolution molecular map of the choroid, supplying blood and oxygen to the outer retina, revealing patterns of protein abundance that may be critical in vision loss. The map helps explain why certain areas are more susceptible to disease and identifies potential treatment targets.

Background TV can be bad for kids

A University of Iowa study found that background TV can divert children's attention from play and learning, negatively affecting cognitive development. Parents who create a loving and nurturing environment with set rules and expectations can help buffer these impacts.

UI study finds potential genetic link between epilepsy and neurodegenerative disorders

A new study at the University of Iowa has identified a potential genetic link between epilepsy and neurodegenerative disorders, revealing a novel pathway involved in the pathophysiology of epilepsy. The researchers found that mutations in prickle genes cause seizures in flies, leading to epilepsy-like behaviors.

Researchers create vaccine for dust-mite allergies

A new vaccine developed by researchers at the University of Iowa reduces lung inflammation caused by dust-mite allergens in both lab and animal tests. The vaccine uses a booster called CpG to alter the body's immune response, producing antibodies that dampen the damaging effects of dust-mites.

Clean air in Iowa

A new study from the University of Iowa reveals that Iowa's air quality is generally clean, but with notable variations between urban and rural areas. The research found higher concentrations of fine particulate pollutants in urban locations, particularly associated with vehicle exhaust and industrial activity.

Infertile women want more support

A study at the University of Iowa found that infertile women want more than just practical aid but also emotional reassurance and empathy. The researchers suggest spouses, friends, and family can help by being more supportive and emotionally invested in the process.

Researchers track down cause of eye mobility disorder

Researchers at the University of Iowa have identified the mutated protein responsible for a common eye mobility disorder. In a study published in Neuron, they found that a unique swelling in one of the nerves to the eye muscle causes the defect, and that breeding mice with this mutation can enhance the effect.

Safety first, children

A University of Iowa study found that mothers and children often disagree on the danger of situations, but mothers can bring their child's thinking around with effective conversations. Mothers use a specific tactic to explain why a situation is dangerous, focusing on present features rather than potential outcomes.

Healthy food is good for you -- and can sell, too

A University of Iowa-led study found that adding healthy foods to concession stands can increase sales and profits while maintaining customer satisfaction. The study, which involved a school booster club in Muscatine, Iowa, showed that introducing healthier options led to stable sales and revenue increases.

Humans have a poor memory for sound

Researchers at the University of Iowa found that humans tend to forget sounds they hear, rather than visual or tactile information. The study suggests that our brain may use separate pathways to process auditory information, and that alternative strategies like increased mental repetition may be needed to improve memory.
