Happy Friday. Let's head into the weekend with a few updates on local innovation stories we've been following:

• Project Waves, the community internet service provider founded by RealLIST Engineers 2020 honoree Adam Bouhmad and fiscally sponsored by Digital Harbor Foundation, has a new partnership with Enoch Pratt Free Library. This will provide internet to 50 homes in Southeast Baltimore, via an antenna that's on the roof of the Southeast Anchor library. The expansion was funded by a $50,000 PNC Foundation grant.
• DataTribe made its investment for the winner of its startup challenge official. The Fulton-based cyber foundry is investing $1.7 million in SightGain, a D.C.-based startup that makes technology to evaluate cybersecurity readiness in production environments, and among personnel.
• emocha Mobile Health said it was granted $1.5 million from the NIH's National Institute on Diabetes and Digestives and Kidney Diseases. This brings the Mount Vernon-based company's total funding from NIH to $6.1 million. The latest funding will allow Johns Hopkins University, the University of Miami, and the University of Virginia to study the effectiveness of emocha's video-based therapy platform for kidney and liver transplant recipients. The company got an initial award for this use case in March.
