Decision to ban unrealistic body images has merit, but presents challenges

A public health measure and a slippery slope. That's how Iowa State University experts describe the decision by London's mayor to ban ads with "unrealistic body images" from the city's public transit system. The ban is intended to limit exposure to ads that can have harmful effects, but it raises questions on how to define what's acceptable.

Breathing new life into schoolyards benefits entire communities

Millions of American elementary school children are sidelined on barren plots of cracked asphalt that resemble parking lots rather than schoolyards. And despite the educational and health benefits of green landscapes, only two major cities in the United States — Denver and Boston — have renovated all of their public schoolyards. Bambi Yost, an Iowa State University assistant professor of landscape architecture, and her students are part of a collaboration of nonprofits, government agencies, landscape architects, schools, community members and universities. Together they are breathing new life into more than 300 neglected schoolyards in the School District of Philadelphia. They represent a burgeoning national movement to green schoolyards.

Workshop to present commercial viability of ‘Hexcrete’ idea for taller wind turbine towers

Iowa State University engineers will explain the benefits of their Hexcrete technology for taller wind turbine towers during a workshop in late June. They'll also discuss how potential partners can be involved in building a full-scale prototype tower. The engineers have been developing the precast concrete technology since 2010.

Even when help is just a click away, stigma is still a roadblock

Stigma is a major barrier preventing people with mental health issues from getting the help they need. Even in a private and anonymous setting online, someone with greater self-stigma is less likely to take that first step to get information about mental health concerns and counseling, according to a new Iowa State University study.

Iowa State University entomologists assess possibility of fighting soybean aphids with other insects

Iowa State University entomologists are studying the possibility of combating soybean aphids, one of the most damaging pests Iowa farmers battle, by introducing a species of stingless wasp that eats them. The harmless, stingless wasps may offer a form of biological control that could suppress soybean aphid populations.

Leath announces initiatives to enhance safety at Iowa State

At the June 9 Iowa Board of Regents meeting, ISU President Steven Leath announced three initiatives to enhance campus safety: development of a body camera policy for ISU Police; a new mobile app that will power the department's safety escort service; and expansion of the Multicultural Liaison Officer program, which began last spring.

Iowa State physicist wins early career awards to study mysterious materials

Iowa State's Rebecca Flint recently won two early career research grants. The support from the U.S. Department of Energy and the National Science Foundation will advance her theoretical studies of unique materials featuring strongly interacting electrons. At low temperatures, these materials obey new laws of physics and have exotic properties.
