Veterinary researchers have discovered that more than 50% of free-roaming cats in New York City carry parasites that could potentially be transmitted to humans. https://phys.org/news/2026-07-hidden-health-york-city-free.html Cell & Microbiology Fri, 10 Jul 2026 10:30:01 EDT news702895994 About 1 in 3 people worldwide have been infected with a microscopic parasite called Toxoplasma gondii—or simply "toxo"—which can cause toxoplasmosis. After the initial infection, toxo settles into our muscles and brains, where it can remain for life. https://phys.org/news/2026-07-people-toxoplasmosis-dangerous-brain-parasite.html Cell & Microbiology Fri, 10 Jul 2026 09:40:04 EDT news702893221 Rutgers Office for Research (OfR) leaders collaborated with researchers around the world to develop an artificial intelligence (AI) program that has the potential to revolutionize lab research. https://phys.org/news/2026-07-lab-animals-ai.html Biotechnology Fri, 10 Jul 2026 08:00:05 EDT news702888117 Scientists have detected the highly contagious H5 bird flu in an Australian seabird for the first time, the government said Friday. https://phys.org/news/2026-07-h5-bird-flu-australian-seabird.html Veterinary medicine Fri, 10 Jul 2026 04:10:01 EDT news702874673 The summer heat can be unrelenting, sending pets who usually run straight to their owners after being outside in search of their water bowls instead. Rehydrating after playtime is important, so if a pet does not have proper access—or a desire to seek out—water, the owner must step in before the companion's health is at risk. https://phys.org/news/2026-07-dangers-dehydration-pets.html Veterinary medicine Thu, 09 Jul 2026 18:40:04 EDT news702815687 Since the U.S. Department of Agriculture confirmed the first case of New World screwworm (NWS) in the United States on June 3, pet owners and shelters alike have expressed concern about what this might mean for their animals. Because the larvae of the parasitic fly infest wounds and can create significant tissue damage if left untreated, veterinarians are encouraging shelters and pet owners, including those who work with colonies of stray or other unowned animals, to remain vigilant and stay informed, especially because NWS infestations can be easily prevented and treated. https://phys.org/news/2026-07-pets-world-screwworm.html Plants & Animals Wed, 08 Jul 2026 22:40:03 EDT news702747009 A rat first frees a cagemate rat and then shares food with it. Is this animal just as empathetic as humans? In an American study from 2011, researchers observed that rats first freed their fellow rats from a cage and then shared food with them instead of leaving them in the cage and eating alone; this means they showed empathy. But do they have the same capacity for empathy as we humans, or do we differ in that regard? https://phys.org/news/2026-07-rats-empathy.html Plants & Animals Sun, 05 Jul 2026 16:00:03 EDT news702217587 As human cases of flea-borne murine typhus continue to occur in South Texas, researchers are working to better understand the role cats and their fleas may play in the disease's transmission cycle. https://phys.org/news/2026-07-feline-fleas-bacteria-linked-human.html Veterinary medicine Thu, 02 Jul 2026 22:00:01 EDT news702210631 In the northern hemisphere, the summer season is rolling in, and the heat is on the rise.

In contrast, chronological age itself was a poor predictor of stride length. A similar reduction in step length has been well documented in people with dementia. These results suggest that a decline in stride length could be an early warning sign of canine dementia, and so an informative new tool for veterinarians. https://phys.org/news/2026-06-shorter-front-leg-early-dementia.html Plants & Animals Thu, 25 Jun 2026 00:00:01 EDT news701451602 Scientists have detected the highly contagious H5 bird flu strain in a second Australian state, the nation's agriculture minister said Wednesday. https://phys.org/news/2026-06-h5-bird-flu-australia-state.html Veterinary medicine Wed, 24 Jun 2026 04:10:02 EDT news701491836 Sight-threatening antibiotic-resistant eye infections are becoming a significant threat to vision in dogs, cats and horses, according to a new comprehensive review published in Veterinary Ophthalmology by researchers from the Hebrew University of Jerusalem. The study examines global trends in antimicrobial resistance in animal eye infections and warns that multidrug-resistant bacteria are becoming more common in referral veterinary settings. The review also highlights a critical challenge for veterinarians: Standard laboratory tests may not always predict how well topical eye treatments will work in practice. https://phys.org/news/2026-06-antibiotic-resistance-threatens-vision-pets.html Veterinary medicine Tue, 23 Jun 2026 15:40:03 EDT news701438821 The dried larvae of the yellow mealworm beetle (Tenebrio molitor) are comparable to beef or poultry in nutritional value, but the mealworm has a far smaller ecological footprint.

In these multicat households, not all the cats get along equally well. Until recently, it was thought that if a cat licks another cat (a behavior known as "allogrooming"), the two cats were friends. But is this really true? Researchers at Ghent University and the University of Lincoln have investigated this behavior. https://phys.org/news/2026-06-cats-groom-friendly.html Plants & Animals Mon, 22 Jun 2026 14:20:01 EDT news701352831 On a remote beach near Esperance, Western Australia, two sick seabirds have brought the bird flu crisis to Australia. https://phys.org/news/2026-06-australia-h5n1-cases-wild-birds.html Cell & Microbiology Mon, 22 Jun 2026 07:40:02 EDT news701330882 Scientists have detected the H5 strain of bird flu in Australia for the first time, the country's agriculture minister said Saturday, meaning the highly contagious variant has now spread to every continent. https://phys.org/news/2026-06-australia-case-contagious-h5-bird.html Veterinary medicine Sat, 20 Jun 2026 02:55:27 EDT news701142893 When H5N1 bird flu first began infecting U.S. cattle in early 2024, diagnosis was elusive because, in cows, the disease looked completely different. Instead of affecting the lungs, as H5N1 does in other mammalian species, it caused severe infection in the cows' udders, largely sparing the lungs. https://phys.org/news/2026-06-h5n1-bird-flu-hid-unrecognized.html Cell & Microbiology Fri, 19 Jun 2026 14:00:05 EDT news700991161 See the vet reports during any yearling sale and you'll hear it—a ripple of concern when a veterinarian flags a bone chip on a radiograph of the horse's leg. Buyers often step away. Prices drop. The horse, in the minds of many, is already compromised. However, findings of a study from the University of Kentucky Maxwell H. Gluck Equine Research Center challenge that assumption, which carries real financial weight for sellers and consignors. https://phys.org/news/2026-06-buyers-assumptions-carpal-chips-thoroughbred.html Veterinary medicine Wed, 17 Jun 2026 22:00:01 EDT news700914741 Husker scientists have developed a new swine influenza vaccination technique whose low cost and adaptability can greatly strengthen disease protection. https://phys.org/news/2026-06-swine-influenza-vaccination-technique-greatly.html Biotechnology Wed, 17 Jun 2026 13:00:06 EDT news700910041 Just 10 viral particles of the H5N1 bird flu that caused hundreds of influenza outbreaks in U.S. dairy cattle can cause infection in cows, a new study shows. The research also hints at why the outbreaks have confounded scientists, farmers and livestock handlers hoping to contain and prevent the disease—an effort likely complicated by the fact that the virus has an affinity for cow mammary glands rather than airways. https://phys.org/news/2026-06-viral-particles-h5n1-avian-flu.html Ecology Mon, 15 Jun 2026 18:00:03 EDT news700758451 University of Melbourne researchers have uncovered several animal welfare issues in the United Kingdom's greyhound racing industry, reigniting public debate about whether the sport should be banned worldwide. https://phys.org/news/2026-06-ai-tool-spotlights-welfare-greyhound.html Veterinary medicine Mon, 15 Jun 2026 11:00:02 EDT news700736761 Taylor & Francis has announced the publication of the first Plain Language Summary of Publication (PLSP) in veterinary research, a milestone in making discoveries in animal health more accessible, engaging and impactful.
