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.

PETA Slaps UMass With Lawsuit for Attempting to Hide Public Records

September 13, 2022

UMass is trying to keep the public in the dark about the grisly marmoset monkey experiments being conducted in experimenter Agnes Lacreuse’s laboratory, going as far as refusing to provide public records that PETA requested. PETA filed a lawsuit with Suffolk County Superior Court in Massachusetts to demand transparency of the taxpayer-funded experiments, including videos of monkeys in stressful social separation tests and a video in which hand warmers are forcefully held on the monkeys’ abdomens.

Brand-New UMass Students Shown the Truth About Monkey Tests on Campus

September 6, 2022

PETA made sure all the new students starting fall semester learned about the university’s appalling monkey menopause experiments. Video footage from the laboratory was displayed on a mobile billboard, and posters were put up all around campus. We raised awareness at the New Student Convocation event, where we passed out leaflets and our reusable “UMass: End Marmoset Experiments” cups to hundreds of students. Students were disgusted to hear about the experiments being conducted at their new university and were eager to learn more about how they could help end the monkeys’ suffering.


PETA Activist Confronts UMass Chancellor About Monkey Experiments

September 3, 2022

Immediately following Chancellor Kumble Subbaswamy’s free-speech presentation on campus, an activist asked him why he had abruptly shut down talks with PETA scientists about ending the university’s gruesome menopause monkey experiments and shifting to a human-relevant, animal-free research program. Subbaswamy had the chance to practice what he preaches, but he refused to discuss the matter. It appears that when experiments rake in over $4 million in taxpayer funds, the chancellor stops caring about free speech. See his reaction here.

PETA Depicts Menopause Monkey Lab: The Dark Side of UMass

August 18, 2022

There’s a dark side to UMass, where greed, secrecy, and killing abound. UMass experimenter Agnès Lacreuse was pulled into it, like a real-life Darth Vader. There’s no doubt the tiny marmoset monkeys, whom she named after Star Wars characters, viewed her as a villain when she drilled into their skulls, cut them open, and forced hand warmers onto their bodies before killing them. Read the full story of Anakin, a marmoset imprisoned and killed in the UMass lab, here.

‘UMass Chancellor, Retire the Monkey Lab on Your Way Out,’ Says PETA

June 30, 2022

Following the announcement that UMass Chancellor Kumble R. Subbaswamy will retire in June 2023, PETA has urged him to retire the school’s shameful marmoset monkey laboratory, too, and release the monkeys to reputable sanctuaries. The chancellor should take advantage of his remaining time at the university and seize this opportunity to leave a legacy that confirms his stated commitment to “create a better, more just world.”

UMass Monkey Escape Hidden From Feds; PETA Files Complaint

May 26, 2022

Records obtained by PETA reveal that a marmoset’s escape in the UMass laboratory in 2017 went unreported to federal agencies—and that the mishandling of primates has only intensified since then. PETA filed complaints with the U.S. Department of Agriculture and the National Institutes of Health, urging them to investigate the school’s possible violations of animal welfare regulations and guidelines as well as its failure to comply with reporting requirements. Read more about UMass’ incompetency here.

Great News! UMass Apparently Nixes Request for Monkey Sleep-Deprivation Experiments

February 8, 2022

Could UMass finally have had enough sense to say NO to one of experimenter Agnès Lacreuse’s heinous experiments? Let’s hope so. Records obtained by PETA show that Lacreuse’s new torture test—in which she planned to blast monkeys with sounds as loud as a lawn mower for six minutes every 15 minutes throughout the night—will not be taking place at the university. Urge UMass officials to shut down the marmoset monkey lab here.

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.

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.

The traveling exhibit dropped by the Amherst North Town Common, but you don’t have to be anywhere near Massachusetts to view it virtually.
