Updates: Campaign to End Deadly Marmoset Experiments at the University of Massachusetts–Amherst

At the University of Massachusetts–Amherst (UMass), experimenter Agnès Lacreuse drills holes into the skulls of small marmosets, threads electrode leads through their abdomens, zip-ties them into restraining devices, and overheats them with hand warmers to simulate hot flashes associated with menopause—which they don’t even experience naturally. PETA is urging the university to ditch these crude and painful tests—and you can help.

Ad: Multiple Federal Violations Detail UMass’ Definition of ‘Love’

October 4, 2021

After Paul Katz, UMass professor and director of neuroscience, claimed that university experimenters “actually love animals a lot,” we ran a full-page ad in The Boston Globe revealing gross negligence in UMass’ treatment of monkeys. Public records obtained by PETA document federal animal welfare violations in the university’s laboratories, resulting in injuries and death for vulnerable marmosets and other animals—a perverse display of “love.”

Gruesome Marmoset Tests Earn UMass an F in Scathing Back-to-School Ad

September 10, 2021

As UMass students hit the books, PETA’s ad calling out the university for its archaic menopause experiments on vulnerable marmosets hit the pages of the Amherst Bulletin. While UMass struggles to learn the basics—for instance, that faking hot flashes using hand warmers in monkeys who don’t experience menopause is patently absurd—other universities have increasingly advanced to using state-of-the-art, non-animal methods.

Baby Mice Drowned, Birds Starved in Devilishly Cruel UMass Laboratories

July 15, 2021

Animals imprisoned in University of Massachusetts–Amherst (UMass) laboratories—aka “hell on Earth”—endure horrors that would make Satan squeal with delight.

PETA Blog: UMass Experimenter’s Make-Believe Science Wouldn’t Even Pass Muster on the Playground

May 19, 2021

Marmosets don’t experience menopause, but UMass experimenter Agnès Lacreuse has hauled in more than $3.8 million in taxpayers’ hard-earned money to play pretend. She’s devised a trick so preposterous that even the first graders sitting in the sandbox are giving her side eye: She uses hand warmers on the tiny monkeys to mimic hot flashes.

PETA’s incisive full-page ads in The Boston Globe and the Daily Hampshire Gazette, which were seen by Massachusetts residents perusing their morning paper the weekend of May 15, pressure UMass to resume negotiations with PETA about swapping its archaic animal experiments for modern methods. University officials had previously met with PETA scientists to discuss reducing suffering in their laboratories but then slammed the door on further dialog.

PETA’s Exhibit Highlights the Plight of Nonconsenting Animals Exploited in Experiments

May 6, 2021

Spotlighting the stories of animals who have been cut open, poisoned, maimed, and killed in a century of painful and deadly experiments, PETA’s “Without Consent” exhibit challenges institutions—including UMass—to rethink this exploitative, expensive, cruel, and archaic idea of science and replace it with state-of-the-art, animal-free research. The traveling exhibit dropped by the Amherst North Town Common, but you don’t have to be anywhere near Massachusetts to view it virtually.
