Money being returned by the MBTA should be directed right back at improving mass transit in Cambridge, especially where it makes up for the state agency’s deficiencies, residents and city councillors said Monday.

Dismay and outrage greeted news Friday that the MBTA’s green line extension spur to Union Square has been delayed to a March opening.

Police released video Monday that shows the stabber in a Saturday road rage incident and the car he fled in, hoping people will come forward with helpful information.

Bless Mazarura’s Bless by Bless capsule collection of limited-edition “luxury wardrobe essentials” is available at a pop-up shop at Cambridgeside until the end of the year, displaying the designer’s African-influenced fashion and uniting continents through his Army of Luv nonprofit line.

An apparent road rage incident resulted in the stabbing of a 34-year-old man Saturday outside the CambridgeSide mall Best Buy.

Delays to the green line extension project will push the start of service back by two months at the Union Square spur – to December, also when the Lechmere stop is expected to reopen. But there will be a five-month delay on the stretch ending at a Medford/Tufts station.

Toscanini’s ice cream is looking to reopen in Lafayette Square at the end of July or beginning of August, making it 3.5 years after closing there for construction of the boutique hotel 907 Main.

Though the Union Square stop on the green line is expected to open as early as October, there’s no sign yet of elevator access from its neighboring parcel, which got its building permit Thursday and could be under construction into the fall of 2024.

There may be a decision by early summer on whether Somerville will be absolved of its $50 million liability for the MBTA green line extension. Cambridge has not asked for relief on its $25 million.

Transit upgrades are in store for the East Cambridge and East Somerville area as plans solidify to open the green line extension and make McGrath Highway more bike and pedestrian friendly.
