Lion with nine lives breaks record with longest swim in predator-infested waters

A record-breaking swim by two lion brothers across a predator-infested African river has been documented in a new study. The researchers say the 1km swim is another example of iconic wildlife species having to make tough decisions to find homes and mates in a human-dominated world. Read more

Researchers discover 'trojan horse' virus hiding in human parasite

An international team has found a new RNA virus that they believe is hitching a ride with a common human parasite. The virus is associated with severe inflammation in humans infected with the parasite Toxoplasma gondii, leading the team to hypothesize that it exacerbates toxoplasmosis disease. Read more

'Ugly' fossil places extinct saber-toothed cat on Texas coast

This fossil looks like a lumpy, rounded rock with a couple of exposed teeth that are a little worse for wear, having been submerged and tumbled along the floor of the Gulf of Mexico for thousands of years before washing up on a beach. But when it was X-rayed a doctoral student saw there was more to Read more

Genes provide hope for the survival of Arabia's last big cat

The release of captive bred animals carefully selected for their genes can make a significant contribution to the successful recovery of the dwindling wild population and avert the prospect of extinction. Despite revealing extremely low levels of genetic diversity in the wild leopard population in O Read more

How did sabre-toothed tigers acquire their long upper canine teeth?

In a groundbreaking study an international team of scientists has investigated the evolutionary patterns behind the development of sabre teeth, with some unexpected results along the way. Read more

Cats purrfectly demonstrate what it takes to trust robots

Would you trust a robot to look after your cat? New research suggests it takes more than a carefully designed robot to care for your cat, the environment in which they operate is also vital, as well as human interaction. Read more

The double-fanged adolescence of saber-toothed cats

How did North America's saber-toothed cats hunt without breaking their unwieldy saber-like canines, which are vulnerable to sideways bending stresses? A paleontologist provides mechanical evidence that during adolescence, when young cats were learning to hunt, their baby teeth remained in place Read more

Dog attacks on mountain tapirs highlight a growing threat to endangered wildlife

Researchers who captured footage of dog attacks on endangered mountain tapirs in Colombia are calling for action to protect threatened wildlife. Read more

Canada lynx historic range in US likely wider than previously thought

A broader past could mean a brighter future for Canada lynx in the U.S., according to recent research. The study indicates that lynx might do well in the future in parts of Utah, central Idaho and the Yellowstone National Park region, even considering climate change and the lack of lynx in those are Read more

Meow or rooaaar: Exotic cats' ability to recognize familiar caregivers' voices

Biologists present compelling evidence that exotic cats possess the remarkable ability to discriminate between familiar and unfamiliar human voices. Read more

A tiny tattoo for a tabby

Researchers have developed an alternative labeling method called 'bio-tagging', which is a microneedle array system that can safely deliver ink in the form of unique number or letter sequences for the identification of animals, which can be used for pets or livestock. This method may be us Read more

Strong connections found between vaccine hesitancy and support for vaccinating pets

Study findings raise the stakes for public health efforts to improve attitudes about vaccination rates across the board. Read more

Scientist discovers potential brain link between stress, emotional eating

Scientists describe how they identified a molecule that may trigger over-consumption of comfort foods after a threatening event. Read more

More than meows: How bacteria help cats communicate

Many mammals, from domestic cats and dogs to giant pandas, use scent to communicate with each other. A new study shows how domestic cats send signals to each other using odors derived from families of bacteria living in their anal glands.  Read more

Infection with common cat-borne parasite associated with frailty in older adults

A new study of 601 older adults found that those with higher serointensity -- or a higher concentration of antibiodies -- to the cat-borne parasite Toxoplasma gondii are more likely to show signs of frailty, including exhaustion, loss of muscle mass and other indications of declining health. T. Gond Read more

City and highway lights threaten mountain lion habitats

Artificial light pollution at night threatens mountain lion habitat, making it a factor to consider for wildlife crossings and land use, finds a new study.  Read more

New secrets about cat evolution revealed

By comparing genomes of several cat species, the project has helped researchers understand why cat genomes tend to have fewer complex genetic variations (such as rearrangements of DNA segments) than other mammal groups, like primates. It also revealed new insights into which parts of cat DNA are mos Read more
