A new study at the University of Iowa reports a potential link between stress hormones and short-term memory loss in older adults. The study, published in the Journal of Neuroscience, reveals that having high levels of cortisol—a natural hormone in our body whose levels surge when we are stressed—can lead to memory lapses as we age.

Pinecone or pine nut? Friend or foe? Distinguishing between the two requires that we pay special attention to the telltale characteristics of each. And as it turns out, us humans aren’t the only ones up to the task. According to researchers at the University of Iowa, pigeons share our ability to place everyday things in categories. And, like people, they can hone in on visual information that is new or important and dismiss what is not. Results are published in the Journal of Experimental Psychology.
Children are experts at getting into danger. So, how can parents help prevent the consequences? One answer, University of Iowa researchers say in a new study, is for parents to better understand how their children rate hazards and then use conversation to explain why certain situations can be dangerous. Results appear in the Journal of Pediatric Psychology.
A University of Iowa researcher and colleague found greater diversity among insects in a rainforest in Peru than theory would predict.
You don't just need to rely on hot dogs and pizza to make a buck at concession stands. A study led by the University of Iowa examined sales, revenues and profits at a booster-run concession stand in Iowa that offered healthy food items, from apples to string cheese, over two fall seasons. The club registered stable sales and revenue, while profits remained intact. Results appear in the Journal of Public Health.
Researchers at the University of Iowa have found that we don’t remember what we hear nearly as well as things we see or touch. In experiments, the team found that memory declined much greater with sounds than with sight or touch, and the forgetfulness began as early as four to eight seconds after being exposed to a sound. The finding suggests our brain may process auditory information differently than visual and tactile information. Results appear in the journal PLoS One.
An University of Iowa study shows that police officers move as much on the job as someone holding a baby or washing dishes. The finding comes from police wearing armbands that monitored their physical activity. Results appear in the Journal of Occupational and Environmental Medicine.

The researchers propose locating everyone within equal distance from the vote recorder or controlling for sound on voters’ microphones. Results appear in the Journal of the Acoustical Society of America.
University of Iowa researchers have developed a new vaccine that protects against lethal pneumonia caused by Staphylococcus aureus (staph) bacteria, including drug-resistant strains like MRSA.

Parents, let your children get messy in the high chair: They learn better that way. That's according to a new study from the University of Iowa, which concludes that a 16-month-old's setting and degree of interaction enhances his or her ability to identify nonsolid objects and name them. Results published in the journal Developmental Science.
A new international arbitration center will help Israelis and Palestinians settle commercial contract disputes to strengthen the regional economy and maybe help bring peace to the region.
Why are men's noses bigger than women's? The answer, according to a new study from the University of Iowa, lies in our physiology. Men's noses are about 10 percent larger than female noses, on average, because males have more lean muscle mass, which requires more oxygen for muscle tissue growth and maintenance. It also explains why we have smaller noses than our ancestors. Results appear in the American Journal of Physical Anthropology.
The happiest patients are those who have regular contact with their doctors. A University of Iowa study finds that VA patients who have established "continuity of care" with primary-care physician are most satisfied with their treatment. The study comes as the American health care system moves to a more team-based approach to care, known as patient-centered medical home. Results appear in the Journal of General Internal Medicine.
Researchers at the University of Iowa have created an implantable bio patch that regrows bone in a living body, using existing cells. The team created a scaffold seeded with plasmids containing the genetic information for producing bone. The plasmids are absorbed by bone cells already in the body, spurring new growth. Potential applications extend to dentistry. Results appear in the journal Biomaterials.
Affluent girls residing in two-parent homes are much less likely to be sexually assaulted than other female youth, according to a new study conducted by University of Iowa School of Social Work professor Amy Butler. The results appear in the Journal of Child Abuse & Neglect.
