Red-necked keelback snakes possess a potent toxin derived from the toads they consume, which can cause severe harm to predators like mongooses. The snakes store these toxins in specialized nuchal glands.
The strain the animals have contains a mutation allowing it to more easily transmit between mammals. It is also a different variation than the ones found in dairy cows and commercial poultry. This one is Eurasian in origin, first seen in 2022. It has been detected in birds that fly along the Pacific Flyway, and is responsible for a mass mortality event in 2023 in northern fur seals on an island in eastern Russia.
Risks of outbreaks with pandemic potential rise with increasing land-use change, biodiversity loss and climate change. The Pandemic Agreement adopted by the World Health Assembly in 2025 marks a historic shift that establishes the One Health approach as a legally binding obligation for pandemic prevention.
An unnamed tourist saw it and told Aidan Moore, who works for Alcatraz City Cruises. Moore told SFGATE that he was initially skeptical, but the guest's iPhone footage left little room for doubt. The video shows, not a sea lion or an otter, but an actual Canis latrans, doggedly dogpaddling, then clambering out of the water, noticeably shaky and struggling to settle tired paws on the craggy rocks.
Bats carry a lot of very deadly pathogens like Ebola virus, Nipah, Hendra, coronavirus, and also rabies virus. People are finding more and more bat-borne viruses. When such viruses are transmitted to humans, the results are often fatal so there's a lot of interest in trying to prevent spillover in the first place.
In a study published in Science Advances, researchers in China fed Aedes aegypti mosquitoes blood that contained either a vaccine against Nipah virus or the rabies virus. The viruses, contained in the vaccines, replicated inside the insects and reached their salivary glands, allowing them to pass on the vaccine when feeding on bats or when the bats ate the insects.
A passerby discovers it first - and lets out a piercing call. Within seconds, everyone in earshot rushes to the scene. It's mayhem... or so it seems. Crows are intelligent, and super chatty. They watch out for one another within tight-knit groups. As adults it's pretty rare for crows to be killed. So when one dies the others notice. Are they just scared? Or is something deeper going on.
A statement by the government's region 5 livestock office for Chiang Mai, said the animals had been infected with canine distemper virus, with veterinarians also identifying mycoplasma bacteria as a secondary infection. Earlier however, Somchuan Ratanamungklanon, director general of the department of livestock development within the Thai agricultural ministry, told the Thai outlet Matichon that the tigers had been infected with feline panleukopenia.
This is exceptionally rapid detection of an outbreak in free-ranging marine mammals, said professor Christine Johnson, director of the Institute for Pandemic Insights at UC Davis' Weill School of Veterinary Medicine. We have most likely identified the very first cases here because of coordinated teams that have been on high alert with active surveillance for this disease for some time.
Our workshop has encountered all kinds of issues with vehicles over the years, but a set of fox cubs is a brand new one for us. At first, our technician thought they might be rats because the cubs are grey, rather than the typical red you would expect of a fox they gave him quite a fright.
Yvonne Ford, 59, from Barnsley, died four months after she suffered a minor scratch when she startled a dog under her sun lounger on a Morocco beach during a holiday in February last year. She did not seek medical treatment at the time. It wasn't until June 2 2025 that Mrs Ford eventually went to Barnsley Hospital with a range of symptoms including severe headaches, nausea, mobility issues and disorientation.
Rats were leaving Manhattan, hurrying across the bridges in single-file lines. Some went to Westchester, some to Brooklyn. It was the pandemic, and the rats, which had been living off the nourishing trash of New York's densest borough for generations, were as panicked about the closure of restaurants as we were. People were eating three meals a day at home, and the rats were hungry.
