Detecting a concealed weapon or threat is not easy, even for experienced police officers

Terrorist attacks and bombings at concerts, sporting events and airports underscore the need for accurate and reliable threat detection. However, the likelihood of a police officer identifying someone concealing a gun or bomb is only slightly better than chance, according to new research from Iowa State University.

Engineer looks to owl wings for bio-inspired ideas for quieter aircraft, wind turbines

Iowa State's Anupam Sharma is running high-powered computer simulations to learn exactly how owl wings manipulate air flow, pressure and turbulence to create silent flight. He and his research partners hope their studies will produce practical ideas for making ultraquiet aircraft and wind turbines.

President Allen outlines five-year Iowa State University tuition plan

Interim President Benjamin Allen presented a plan to the Iowa Board of Regents Tuition Task Force on Aug. 9 that would increase resident undergraduate tuition by 7 percent in each of the next five years. If approved by the regents, that would add $522 to the base tuition starting in fall 2018, and gradually rise to $684 more per year by fall 2022. The proposal also recommended a 4 percent increase for nonresident undergraduates and differential adjustments for students majoring in engineering, business and some science, technology and experiential learning programs that have a higher cost of delivery.

New study from Iowa State University biologist tracks nonnative plant species in timing of grassland green-up

The introduction of exotic, nonnative plant species to U.S. grasslands has led to changes in prairie phenology, or the timing of season changes. A new study from an ISU scientist details the magnitude of those changes.

Saving the monarch butterfly: Iowa State University biologist explains census discrepancy

New research from an ISU biologist provides an explanation for why citizen scientists taking censuses of monarch butterfly populations didn’t note the same drops in population recorded in Mexico, where the monarchs spend their winters. The research supports previous studies suggesting that an increase in available milkweed could help the monarch population rebound.
