In the next four years, Cambridge streetlights will be outfitted with wireless sensors collecting data on air pollution and weather for use by researchers. Harvard announced today that it’s launching a new project, CitySense, in collaboration with a Cambridge high-tech firm, BBN Technologies, and the city of Cambridge to install about 100 sensors that will measure parameters like temperature, wind speed, and air quality.

Majid Ezzati from the Harvard School of Public Health will use the environmental data as part of his work on the effect of air pollution on health. The idea is that eventually, these devices will collect other types of data that other researchers could use.

Green building frenzy has overtaken Boston. Not only is the city requiring private builders to meet minimum energy-efficiency standards, but local hospitals, undergoing a bit of a construction boom, say their new buildings will exceed those targets.

Novartis, the drug company you can’t miss if you’re on Mass Ave in the Central Square area, is set to get bigger, according to the Boston Business Journal. Cambridge’s largest tenant is negotiating to buy up even more office/lab space to house its vaccines and diagnostics division, which is moving to Cambridge. It has about 100 new jobs available in this division, and has been flooded with job applications. It already employs more than 1,300 people in Cambridge.
