Urge Universities to Cut Ties With Deadly Navy Animal Tests

Two universities are partnering with the U.S. Navy to torment animals in gruesome and deadly decompression sickness/illness and oxygen toxicity experiments that are outdated, wasteful, and out of step with international standards.

This doomed animal in a hyperbaric chamber is one of the countless rats who University of South Florida experimenter Jay Dean has used to supposedly study oxygen toxicity in humans, even though human-relevant, animal-free methods are widely available.

PETA previously contacted the Navy and ended such experiments on sheep at the University of Wisconsin-Madison two years early, saving animals from painful cardiovascular collapse, spinal cord injuries, and paralysis.

With your help, we can do it again. PETA is now urging leaders at the following universities to end the cruelty happening on their campuses:

Duke University

The Navy pays experimenter Heath Gasier nearly $845,000 to induce seizures in young mice, subject them to high-pressure oxygen in hyperbaric chambers, force them to run on a treadmill using electric shocks, and gas them to death. The test is scheduled through January 2026.

University of South Florida

The Navy gave experimenter Jay Dean more than $1 million to induce seizures in rats without pain relief, implant recording devices in their abdomens, thread wires through their bodies, and implant electrodes on their skulls before killing them all. The tests are scheduled through June 2026.

This rat, with drastically different physiology from humans, was locked in a hyperbaric chamber and forced to undergo an agonizing decompression test conducted by University of South Florida experimenter Jay Dean.

Navies in France and the U.K. have already banned these types of experiments on animals, making these universities complicit in keeping our country an outlier. Even the U.S. Naval Medical Research Center admits that such tests are unhelpful for humans, noting that “animal DCS in many cases is more severe than that in humans and, therefore, appears ‘different’ from the average human case.”

In this distressing test, University of South Florida experimenter Jay Dean inserted electrodes into sensitive rats and subjected them to the harrowing conditions of a hyperbaric chamber, even though rats are not biologically accurate stand-ins for humans.

What You Can Do

Please politely urge these universities to end deadly and irrelevant tests on animals in favor of superior, human-relevant, non-animal research methods.

You can contact university officials with one message—just copy and paste this block of e-mail addresses in the “To” field of your e-mail: [email protected]; [email protected]

You’re welcome to use the following talking points, but putting them in your own words will be more effective:

  • Please immediately stop all U.S. Navy–funded decompression sickness and/or oxygen toxicity tests on all animals at your university.
  • The navies of France and the U.K. have banned decompression sickness tests on animals. The U.S. should follow suit.
  • More effective, ethical, and economical animal-free research methods are available.

Then Urge an End to These Experiments Nationwide

Once you’ve told the universities to cut ties with the Navy’s cruel tests, take the next step: tell the U.S. Department of War to ban all decompression sickness and oxygen toxicity experiments on animals.
