Rabbits with ‘horns' in Colorado are being called ‘Frankenstein bunnies.' Here's why
DENVER — A group of rabbits in Colorado with grotesque, horn-like growths may seem straight out of a low-budget horror film, but scientists say there's no reason to be spooked — the furry creatures merely have a relatively common virus.
The cottontails recently spotted in Fort Collins are infected with the mostly harmless Shope papillomavirus, which causes wart-like growths that protrude from their faces like metastasizing horns.
Viral photos have inspired a fluffle of unflattering nicknames, including 'Frankenstein bunnies,' 'demon rabbits' and 'zombie rabbis.' But their affliction is nothing new, with the virus inspiring ancient folklore and fueling scientific research nearly 100 years ago.
The virus likely influenced the centuries-old jackalope myth in North America, which told of a rabbit with antlers or horns, among other animal variations. The disease in rabbits also contributed to scientists' knowledge about the connection between viruses and cancer, such as the human papillomavirus that causes cervical cancer.
The virus in rabbits was named after Dr. Richard E Shope, a professor at The Rockefeller University who discovered the disease in cottontails in the 1930s.
News about the rabbit sightings in Fort Collins, 65 miles (105 kilometres) north of Denver, started getting attention after residents started spotting them around town and posting pictures.
Kara Van Hoose, a spokesperson for Colorado Parks and Wildlife, told The Associated Press on Wednesday that the agency has been getting calls about the rabbits seen in Fort Collins.
But she said that it's not uncommon to see infected rabbits, especially in the summer, when the fleas and ticks that spread the virus are most active. The virus can spread from rabbit to rabbit but not to other species, including humans and pets, she said.
The growths resemble warts but can look like horns if they grow longer, Van Hoose said. The growths don't harm rabbits unless they grow on their eyes or mouths and interfere with eating. Rabbits' immune systems are able to fight the virus and, once they do, the growths will disappear, she said.

Hundreds may have been exposed to rabies at bat-infested cabins in Grand Teton National Park
Health officials are working to alert hundreds of people in dozens of states and several countries who may have been exposed to rabies in bat-infested cabins in Wyoming's Grand Teton National Park over the past few months. As of Friday, none of the bats found in some of the eight linked cabins at Jackson Lake Lodge had tested positive for rabies. But the handful of dead bats found and sent to the Wyoming State Veterinary Laboratory in Laramie for testing were probably only a small sample of the likely dozens that colonized the attic above the row of cabins, Wyoming State Health Officer Dr. Alexia Harrist said. Other bats weren't killed but got shooed out through cabin doors and windows. Meanwhile, the vast majority never flapped down from the attic into living spaces. Health officials thus deemed it better safe than sorry to alert everybody who has stayed in the cabins recently that they might have been exposed by being bitten or scratched. Especially when people are sleeping, a bat bite or scratch can go unseen and unnoticed. 'What we're really concerned about is people who saw bats in their rooms and people who might have had direct contact with a bat,' Harrist said Friday. The cabins have been unoccupied, with no plans to reopen, since concessionaire Grand Teton Lodge Company discovered the bat problem July 27. Bats are a frequent vector of the rabies virus. Once symptoms occur — muscle aches, vomiting, itching, to name a few — rabies is almost always fatal in humans. The good news is a five-shot prophylactic regimen over a two-week period soon after exposure is highly effective in preventing illness, Harrist noted. The cabins opened for the summer season in May after being vacant over the winter. Based on the roughly 250 reservations through late July, health officials estimated that up to 500 people had stayed in the cabins. They were trying to reach people in 38 states and seven countries through those states' health agencies and, in the case of foreign visitors, the U.S. Centers for Disease Control and Prevention. Others who have not been alerted yet but stayed in cabins 516, 518, 520, 522, 524, 526, 528 and 530 this year should tell health officials or a doctor immediately, Harrist said. Health officials were recommending prophylactic shots for people who fit certain criteria, such as deep sleepers who found a bat in their room, and children too young to say that they had seen a bat. The Wyoming Department of Health had no ongoing concern about visitor safety at the Jackson Lake Lodge area. That includes a Federal Reserve economic policy symposium Aug. 21-23 that takes place at Jackson Lake Lodge every summer. 'The lodge company has done a fantastic job of doing their due diligence of making sure everyone that is coming in for that, and for all other visits this year, are going to be as safe as possible,' said Emily Curren, Wyoming's public health veterinarian. 'Three or four' dead bats from the cabins tested negative and one that was mangled did not have enough brain tissue to be testable, Curren said. All were brown bats, which come in two species: 'little' and 'big,' with the larger ones more than twice as big. Officials were unsure which species these were, but both are common in Wyoming. They typically live in colonies of 30 to 100 individuals, Curren said. 'That's a lot of bats that we cannot rule out a risk of rabies being in,' Curren said. 'There's no way for us to know for certain about every single bat that got into these rooms.' There are no plans to exterminate the bats, Grand Teton National Park spokesperson Emily Davis said. Devices fitted to the building were keeping the bats from getting back in after flying out in pursuit of insects to eat, they said. Sejal Govindarao And Mead Gruver (), The Associated Press

Novo Nordisk's Wegovy gets accelerated U.S. approval for liver disease
Novo Nordisk said on Friday the U.S. Food and Drug Administration had granted accelerated approval for its weight-loss drug Wegovy to treat a serious liver condition known as metabolic dysfunction-associated steatohepatitis. The decision makes Wegovy the first GLP-1 class therapy cleared for MASH, a progressive liver condition that affects around 5% of adults in the U.S., according to the American Liver Foundation. The approval is for use alongside a reduced-calorie diet and increased physical activity. The FDA's approval was based on part one of a two-part study that showed Wegovy helped more patients with MASH and liver scarring improve the organ's condition, compared to a placebo. At 72 weeks, nearly 37% of patients on Wegovy saw an improvement in liver fibrosis, compared to 22.4% on placebo. Nearly 63% of those on Wegovy had their liver inflammation resolved, versus 34.3% for placebo. No worsening of the disease was seen in these patients. Accelerated approvals allow the agency to move therapies that target serious and life-threatening conditions to the market more quickly. However, such approvals have been criticized because some drugs have later been proven to be ineffective.
