Breathing carbon dioxide can trigger panic attacks, but the biological reason for this effect has not been understood. A new study by University of Iowa researchers shows that carbon dioxide increases brain acidity, which in turn activates a brain protein that plays an important role in fear and anxiety behavior.
New research shows people who feel depressed tend to recall having more physical symptoms than they actually experienced.
A study by developmental scientists at the University of Iowa and Indiana University challenges the conclusions of two recent studies on how babies and dogs respond to certain social cues. The new findings, published in this Friday's edition of the journal Science, indicate that babies and dogs may not be as clever as the other studies suggest.
The blood brain barrier is generally considered an obstacle to delivering therapies from the bloodstream to the brain. However, University of Iowa researchers have discovered a way to turn the blood vessels surrounding brain cells into a production and delivery system for getting therapeutic molecules directly into brain cells.
By investigating a rare and severe form of diabetes in children, University of Iowa researchers have discovered a new molecular mechanism that regulates specialized pancreatic cells and insulin secretion. The mechanism involves a protein called ankyrin, which UI researchers previously linked to potentially fatal human heart arrhythmias.
Discovery of a deafness-causing gene defect in mice has helped identify a new protein that protects sensory cells in the ear, according to a study led by University of Iowa researchers. The findings, which also involved Kansas State University, appear in the Aug. 21 issue of the open-access journal PLoS Genetics.
Being active at age 5 helps kids stay lean as they age even if they don't remain as active later in childhood, a new University of Iowa study shows.
Scientists in a network of medical research institutions across the United States are set to begin a series of clinical trials to gather critical data about influenza vaccines, including two candidate H1N1 flu vaccines. The research will be under the direction of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
It's easy to explain why we act a certain way by saying "it's in the genes," but a group of University of Iowa scientists say the world has relied on that simple explanation far too long.
HOUSTON -- (June 17, 2009) -- An overactive enzyme is behind a leaky calcium channel that plays a role in the development of atrial fibrillation, which is the most common cardiac arrhythmia that is responsible for a third of all strokes. However, it doesn't act alone, say researchers at Baylor College of Medicine.
A research team led by a University of Iowa investigator has generated DNA-like compounds that effectively inhibit the cells responsible for systemic lupus erythematosus -- the most common and serious form of lupus. There currently is no cure for this chronic autoimmune condition that damages the skin, joints and internal organs and affects an estimated one million Americans.
ATS 2009, SAN DIEGO? A protein from algae may have what it takes to stop Severe Acute Respiratory Syndrome (SARS) infections, according to new research.
The recent H1N1 influenza epidemic has raised many questions about how animal viruses move to human populations. One potential route is through veterinarians, who, according to a new report by University of Iowa College of Public Health researchers, are at markedly increased risk of infection with zoonotic pathogens -- the viruses and bacteria that can infect both animals and humans.
Combating several human pathogens, including some biological warfare agents, may one day become a bit easier thanks to research reported by a University of Iowa chemist and his colleagues in the April 16 issue of the journal Nature.
How will plant cells that live in the oceans and serve as the basic food supply for many of the world's sea creatures react to climate change?
A University of Iowa biologist and faculty member in the Roy J. Carver Center for Comparative Genomics and his colleagues came one step closer to answering that question in a paper published in the April 9 issue of the journal Science.
