Research work at the University of Massachusetts expanded by 23% over the past five years, with almost all of it in STEM fields and a portfolio that’s the fourth largest in New England, behind Harvard University, MIT and Yale University.

UMass on Wednesday released its annual report on research enterprise across its five-campus system. Research work grew 8% in fiscal 2022 over fiscal 2021, to reach $813 million, the report said. The growth marked a second straight year of success in the research realm, coming on top of a 9.4% surge in R&D spending at UMass between fiscal 2020 and fiscal 2021.

Over the past five years, state and local support for UMass research work was down 20%, to $28.5 million. The university made up for that decline in other areas. The federal government boosted support by 28% over that same period to nearly $484 million while institutional support jumped 17% to nearly $213 million.

The biggest buckets of research spending in fiscal 2022 occurred at the Chan Medical School in Worcester ($358 million) and at the flagship campus of UMass Amherst ($245 million).

Warner Bros. Discovery unveiled a streaming service Wednesday combining iconic HBO programming such as “The Sopranos” with a mix of unscripted TV series in a push to reap more subscribers from what so far has been a muddled media merger.

The $16-per-month service, called Max, will be released May 23 in the U.S. and automatically replace the company’s existing HBO Max service in what is being promised as a seamless transition.

The existing Discovery Plus app featuring reality and unscripted series such as “Fixer Upper” from a collection of TV networks will still be offered.
