The results are ready from a national centers for disease control (CDC) study of tick-borne diseases in the Island Wampanoag population, but the outbreak of swine flu may delay their release, the tribe’s environmental health coordinator Cynthia Robinson said this week.

The study is a key feature of a wide-ranging environmental health exposition this Saturday, put on by the Wampanoag Tribe of Gay Head (Aquinnah). The event runs from 9 a.m. to 4 p.m. at the Harbor View hotel in Edgartown.

The Edinburgh Fringe Festival — it’s the biggest arts festival in the world, and the drama department at the Martha’s Vineyard Regional High School, under the direction of Kate Murray, has been chosen as one of the U.S. representatives for its 2010 lineup.

Calling Volunteers

The American Red Cross, Cape Cod and Islands chapter, is looking for additional volunteers in disaster services and for general support in the next few months. Training will be provided free of charge.

West Tisbury author Cynthia Riggs will talk about her latest book Death and Honesty, the eighth in her Martha’s Vineyard mystery series, at the Chilmark Public Library on Wednesday, May 20, at 5:30 p.m.

Matzo & Mistletoe, a documentary from Vineyard-based filmmaker and author Kate Feiffer, will screen on Thursday, May 21, at 6 p.m. at the Oak Bluffs Public Library.

Ms. Feiffer was six years old when her father told her she was Jewish. Since she celebrated Christmas and never attended synagogue, this information came as a surprise. In Matzo & Mistletoe, she interviews a fascinating cast of characters, and uses archival footage, illustration and clips from television shows and movies to ponder the paradox of American secular Judaism.

The Vineyard Sinfonietta presents a spring concert Tuesday, May 26, from 3 to 4:30 p.m. at the Oak Bluffs Library.

Encore selections will feature baritone Howie Marlin (and, in one piece. his daughter, Hannah) in three pop songs by Cole Porter, Jimmy VanHeusen and Matt Dennis, plus other songs made famous by Frank Sinatra.
