Rhesus monkeys getting treats from their caregiver at the Wisconsin National Primate Research Center. Healthy treats can include peanuts, grapes, apple slices, etc. Positive reinforcement is used to train the monkeys to move to transport boxes. These boxes safely carry monkeys to procedure rooms for blood draws, ultrasounds, TB…
Environmental enrichment is an important part of caring for research animals. Research animals are provided with several types of enrichment to stimulate species-typical behaviors. These juvenile rhesus macaques are enjoying mini marshmallow treats. Interactions with their caregiver give them social and intellectual stimulation, while strengthening their bonds with…
A rhesus macaque mom climbs into a hammock with her infant at the Wisconsin National Primate Research Center. Females reach puberty at around age three, while males are sexually mature by age four. Gestation is five and a half months, with one infant born at a time and often a…
Love, Care, Progress: Research Involving Dogs is the inaugural video in the Love, Care, Progress series, focused on the important role of canines in health research which benefits humans and dogs alike. Research professionals, including a trainer, scientist, animal behaviorist, surgical manager, and veterinarian talk about caring for…
Embryonic development takes place rapidly. It is also a key area of study during drug safety testing. This photo shows thirty-day-old zebrafish embryos. Because they are transparent, researchers can easily monitor the development of the embryo from fertilization to when it hatches as larval fish. The embryo in…
Nanoparticles carrying two drugs can cross the blood-brain barrier and shrink glioblastoma tumors.
Adult tissues retain — and can recover — a memory of their early development, which might be a game-changer for cancer and regenerative medicine
Chinchillas serve as vital models for auditory system research due to their physiological similarities to humans, aiding advancements in acoustic studies and offering insights into middle ear infections and other areas like respiratory infections and ototoxicity.
Xenopus frogs, pivotal in vertebrate embryology, cell biology, genomics, and disease research, aid in understanding embryonic development, environmental adaptation, and the causes of diseases and birth defects.
Rhesus macaque monkeys, owing to their anatomical and physiological likeness to humans, have been instrumental in developing life-saving vaccines and treatments like those for polio, smallpox, rabies, and HIV/AIDS. They've also contributed to behavioral discoveries, showing promise in neural mechanism studies.
