In a laboratory at the University of Massachusetts at Amherst, graduate students hover around a complex setup that involves tubes, chambers, and dials. The students load sawdust into one side of the machine and, within moments, a brown liquid begins to drip into a catch basin on the other side.

The liquid - known as green gasoline - is the chemical equivalent of traditional gasoline, but cleaner and less expensive. According to its inventor, that means the green gas, also referred to as grassoline, has the potential to transform the economy.

Knee-surgery devices maker raises $50 million

A Burlington medical device company, ConforMIS Inc., is set to disclose today that it has raised $50 million from a consortium of private equity firms and sovereign wealth funds, one of the largest investments in a Massachusetts life sciences company this year.

Last week, Google declared an end to “beta,’’ or test status, for its online office software, Google Apps, as part of a new effort to sell the service to corporate users. Then the company said it’s building Chrome OS, a full-fledged operating system for personal computers that will compete with Microsoft Windows. It’s due next year.
