University of Massachusetts Lowell held the fourth annual 2016 DifferenceMaker $35K Idea Challenge on April 13. Participants were invited to create new products, services, and technologies to solve problems in business and the community, and then pitch them to a panel of judges. A team of UMass Lowell students called Team eNABLE took the top prize of $6,000 for their prosthetic hand design. The money, given to help further their business idea, was raised by alumni.

Sarah Boermeester, a student of Dracut High School, was named the winner of the 2016 Congressional Art Competition across the Third District. Congresswoman Niki Tsongas awarded the prize to Boermeester at a reception in April, naming her piece, “Clementines,’’ the best out of 67 pieces of art, the most entries ever. It will be displayed in the Capitol for one year, and she will receive an artistic scholarship as well as two airplane tickets to Washington, D.C., to participate in the national ceremony.
