For Your Information

Concern has been spreading across scientific disciplines that the pervasive human transformation of Earth's natural systems is an urgent threat to human health, and Cornell's College of Veterinary Medicine is helping to forge a new field to meet unprecedented challenges.

Cornell researchers have developed a new process using nanoscale technology that can detect multiple pathogens at once, and are now adapting this method to more efficiently test different types of ticks for a large number of disease agents.
Students helping treat leopard

College of Veterinary Medicine students have partnered with the Belize Zoo and Tropical Education Center, gaining valuable experiences they will never forget.
Bald Eagle landing on branch

Bald eagles have made a successful comeback since their numbers dwindled due to human pressures in the early 1900’s. However, the charismatic national bird is threatened once again, this time from a different human-driven cause: lead.
Diamondback Terrapin

Cornell scientists and partners have discovered that saxitoxin, a potent neurotoxin from algal blooms, was the cause of a massive die-off of diamondback terrapin turtles and fish. Understanding what's happening in this fragile ecosystem is key to preventing future crises - for wildlife and people.
Kids and fish

Hundreds of students ranging from fourth-graders to high school seniors across New York State are engaging in a hands-on scientific project with Cornell University by collecting water samples and evaluating environmental DNA to monitor the spread of invasive fish species, providing a real-world lesson in ecology and environmental management.
Earth and Hands


Dr. Steve Osofsky discusses the challenges of responding to zoonotic disease in Africa.
hammerhead shark swimming

A new study of shark DNA, including from great white and great hammerhead sharks, reveals unique modifications in their immunity genes that may underlie their rapid wound healing and possibly higher resistance to cancers.
moose in a field

College of Veterinary Medicine researchers and partners are evaluating the health of moose populations across the New York Adirondacks region. By screening animals for infectious diseases and developing health indicators for evaluation over time, we can assess factors key for ensuring the population's long-term viability.

For Your Information

Cornell veterinary students are benefiting from international experience that ties coursework in language, culture, and research to hands-on fieldwork. They are able to spend eight weeks in Indonesia, Uganda, or the Republic of Congo to experience first-hand how the health of wildlife, domestic animals and people - and the health of the environment - are all deeply interconnected.
