Who trusts gene-edited foods? New Iowa State University study gauges public acceptance

By Rachel Cramer, Iowa State University News Service

Through CRISPR and other gene-editing technologies, researchers and developers are poised to bring dozens – if not hundreds – of new products to grocery stores: mushrooms with longer shelf lives, drought-resistant corn and bananas impervious to a fungus threatening the global supply. A few, including a soybean variety that produces a healthier cooking oil, are…


Theoretical calculations predicted by Iowa State Researcher now-confirmed tetraneutron, an exotic state of matter

By Mike Krapfl, Iowa State University News Service

James Vary has been waiting for nuclear physics experiments to confirm the reality of a “tetraneutron” that he and his colleagues theorized, predicted and first announced during a presentation in the summer of 2014, followed by a research paper in the fall of 2016. “Whenever we present a theory, we always have to say we’re…


Iowa State Engineers develop cybersecurity tools to protect solar, wind power on the grid

By Mike Krapfl, Iowa State University News Service

Solar panels and wind turbines, now projected to produce 44% of America’s electricity by 2050, present cybersecurity challenges. They have sensors, controllers, actuators or inverters that are directly or indirectly connected to the internet. They’re distributed far and wide across the country and the countryside. Many have insecure connectivity to legacy electric grid systems. They have…


Iowa State Study shows how artificial light affects seasonal rhythms of plants in U.S. cities

By Angie Hunt, Iowa State University News Service

A new study led by Iowa State University researchers shows how artificial light has affected the natural seasonal processes of plants in urban regions of the United States. The study, published in the peer-reviewed academic journal PNAS Nexus, demonstrates how urbanization affects the natural world, resulting in noticeable changes for humans, said Yuyu Zhou, associate professor of…


Startups near state lines gravitate toward side with lower property tax, according to Iowa State Study

By Rachel Cramer, Iowa State University News Service

Researchers at Iowa State University found significantly different state tax rates affect where new businesses set up shop near state lines. Their study published in the journal Small Business Economics shows the fourth greatest distortion in the U.S. is between Iowa and its northwest neighbor. “The probability of starting up on one side of the border versus…


Iowa State Researchers reveal the origin story for carbon-12, a building block for life

By Mike Krapfl, Iowa State University News Service

With the help of the world’s most powerful supercomputer and new artificial intelligence techniques, an international team of researchers has theorized how the extreme conditions in stars produce carbon-12, which they describe as “a critical gateway to the birth of life.” The researchers’ fundamental question: “How does the cosmos produce carbon-12?” said James Vary, a…
