   I didn't think for a minute that I'd be able to contribute anything of
   use to this group, but I just happened to be reading through back issues
   of SCIENCE NEWS and remembered a reference to the Braam study.

   The summary is in SCIENCE NEWS, Vol. 137, No. 8, page 117; Feb. 24, 1990,
   and the published study is in CELL, Feb. 9, 1990.

   I hope this is of some use, even though it's a week late.
