Electrical engineers at Duke University have demonstrated the ability to print fully functional and recyclable electronics at sub-micrometer scales. The technique could impact the more than $150 billion electronic display industry and its environmental impact while providing a toehold for U.S. manufacturing to gain traction in a vital and quickly growing industry.

Scientists at the University of Utah and Sethera Therapeutics have discovered an enzyme that can reshape therapeutic peptides—including GLP-1 drugs used for diabetes and obesity—into more stable, ring-shaped forms. New research could help accelerate drug development.

The faster a child takes bites during a meal or snack, the greater risk they have for developing obesity, according to researchers in the Penn State Department of Nutritional Sciences. But research into this association is often limited to small studies in laboratory environments, largely because counting a child’s bite rate is difficult; it requires someone to watch videos of a child eating and manually record each bite.
