This week, three papers came out describing new approaches to folding DNA into large complex shapes—20 times bigger than previous DNA sculptures. Staff Writer Bob Service talks with Sarah Crespi about building microscopic teddy bears, doughnuts, and more from genetic material, and using these techniques to push forward fields from materials science to drug delivery.
Sarah also interviews Philip Cook of Duke University in Durham, North Carolina, about his Policy Forum on gun regulation research. It’s long been hard to collect data on gun violence in the United States, and Cook talks about how some researchers are getting funding and hard data. He also discusses some strong early results on open-carry laws and links between gun control and intimate partner homicide.
