Over a typical two-year rotation of corn and soybeans, 40% of nitrous oxide emissions are in the fertilizer-free soybean year, according to new Iowa State University research. Winter cover crops and planting soybeans earlier could reduce emissions of the potent greenhouse gas by one-third while increasing yields.
The interplay between the genetic makeup of crops and the conditions in which they grow is difficult to untangle. A research team led by an Iowa State University professor aims to help breeders analyze the interactions to make crops more resilient and productive.
A new study led by an Iowa State University evolutionary biologist described for the first time the three-dimensional architecture of turtle genomes, which fold in a configuration unlike any other animal observed so far.
"Cyber House Rock!" is a fresh and helpful way for people to learn a few basics about securing their digital information. The series of music videos, with more to come, launches during this year's Cybersecurity Awareness Month.
Researchers examined the costs of weather-related damage and destruction for companies and government agencies with multiple buildings. The researchers focused on the large building portfolio of the U.S. Department of Defense. Their study aims to help organizations plan for the rising costs associated with long-range facilities maintenance and replacement.
A research team at Iowa State University has found that zinc supplements may be an inexpensive, effective antidote to the growing health threat of antimicrobial resistance, potentially extending the effectiveness of today’s antibiotic arsenal against disease.
An Iowa State engineer is leading development of cybersecurity tools to guard power grids that carry renewable energy resources such as such as wind or solar farms. The researchers will develop "zero-trust" tools to reduce cyber exposure. The U.S. Department of Energy is supporting the project.
An Iowa State University plant biologist received a $1.8 million federal grant to study a gene that affects both how plants grow and how they respond to environmental threats. Unraveling the balancing act between fortifying and flourishing could help scientists develop crops that are more resilient in challenging conditions.
Sougata Roy and his DREAM-TEAM collaborators are studying 3D printing as an alternative way to process tungsten for use as shields and other components in nuclear reactors. The project is supported by a new, $1 million grant from the U.S. Department of Energy.
Iowa State's Valery Levitas and his collaborators have used pressure with a twisting shear to permanently deform silicon, an important material for electronics. The resulting changes in silicon's microstructure produce material phases that feature different and potentially useful properties.
A research team led by Iowa State's Zhaoyu Wang will study electric vehicle charging stations with a goal of developing strategies and technologies to keep the chargers operating, even when storms hit and the power goes out.
A new USDA-supported project based at Iowa State University will create an encyclopedia of livestock species' genetic regulatory regions, a DNA netherworld that could be useful in breeding for improved animal efficiency and health.
An Iowa State University research team has discovered when and why inflammatory signaling affects the formation of blood stem cells in embryos, which will benefit efforts to develop lab-grown, patient-derived stem cell transfusions to treat blood disorders. The promising advancement in regenerative medicine could eliminate the need for bone marrow transplants.
A research team led by Iowa State's Qi An has developed artificial intelligence technology that could find ways to improve researchers’ understanding of the chemical reactions involved in ammonia production and other complex chemical reactions.
The economic impact of porcine reproductive and respiratory syndrome increased 80% between 2010 and 2020, costing the pork industry more than $1 billion per year in lost production, according to a new study. Researchers say improved biosecurity is essential to reversing the mounting losses.
As we use electricity to power more and more -- everything from vehicles to lawn mowers -- it's getting harder for utilities to manage the distribution transformers that are in every neighborhood. Iowa State's Zhaoyu Wang is leading an effort to develop a system that will help utilities maintain the important links between the power grid and homes, farms and businesses.
A new study by a broad team of researchers at Iowa State University’s College of Veterinary Medicine helps explain why dairy cows infected by highly pathogenic avian influenza are shedding the virus in their milk. Their findings could help develop biosecurity measures aimed at slowing the spread of the illness.
Matthew Panthani and his research group are developing new materials that allow semiconductors to emit light. The resulting integrated photonic circuits could make computers, phones and other electronics faster and more energy efficient. The National Science Foundation is supporting the work with a $552,000 grant.
