Grant will help scientists break new ground in gene editing

A new grant from the National Institutes of Health will allow Iowa State University scientists to continue to develop gene editing technologies to model human disease in zebrafish. The research aims to build new tools to determine which genes have therapeutic potential to treat human genetic diseases that affect the cardiovascular, immune and nervous systems.

Scientists developing portable viral tests for future pandemics

Iowa State University researchers are developing a portable, inexpensive technology that could allow people to test for the presence of a virus or antibodies without having to go to a medical facility. The technology is still about a year away, but it could come in handy in the event of a resurgence of the coronavirus or for future pandemics.

Study gauges insecticide effects on monarch butterflies

A newly published study sheds light on how insecticides commonly applied to crops affect monarch caterpillars. Conservation efforts to protect monarch butterfly populations depend on planting milkweed on agricultural land, but doing so may put caterpillars in close proximity to harmful insecticides.

Sorghum study illuminates relationship between humans, crops and the environment in domestication

A new study illustrates the concept of a domestication triangle, in which human genetics interact with sorghum genetics and the environment to influence the traits farmers select in their crops. The concept gives a more complete systemic picture of domestication.

Regional trends in overdose deaths reveal multiple opioid epidemics, according to new study

A recently published study shows the United States in the grip of several simultaneously occurring opioid epidemics, rather than just a single crisis. The epidemics came to light after the researchers analyzed county-level data on drug overdose deaths. The study highlights the importance of different policy responses to the epidemics rather than a single set of policies.
