  • iconProtected habitats near US borders
    The clustering of protected habitats in the Americas near international borders makes many iconic, wide-ranging animals physically dependent on good relations between neighboring countries and wildlife-friendly borders.
  • iconEarly-life exposure to dogs may lessen risk of developing schizophrenia
    Ever since humans domesticated the dog, the faithful, obedient and protective animal has provided its owner with companionship and emotional well-being. Now, a study suggests that being around 'man's best friend' from an early age may have a health benefit as well -- lessening the chance of developing schizophrenia as an adult.
  • iconJewel beetles' sparkle helps them hide in plain sight
    Bright colors are often considered an evolutionary tradeoff in the animal kingdom. Yes, a male peacock's colorful feathers may help it attract a mate, but they also make it more likely to be seen by a predator. Jewel beetles and their iridescent wing cases may be an exception to the rule, researchers report. They found that the insects' bright colors can act as a form of camouflage.
  • iconGene hunting: The power of precision medicine
    Humans and animals are made up of trillions of cells, and each cell contains DNA specific to that individual. Therefore, identifying DNA that causes genetic disorders gives researchers and clinicians a better understanding of how to treat inherited diseases and possibly prevent the diseases from being passed down to future generations.
  • iconHow and when spines changed in mammalian evolution
    Researchers compared modern and ancient animals to explore how mammalian vertebrae have evolved into sophisticated physical structures that can carry out multiple functions. The comparison between complex spine of cats, the more uniform spine of lizard, and CT scans of synapsid fossils showed that the evolution of functions (e.g. bending, twisting) is driven by both selective pressures/behavior and the evolution of independent sections of the spine. The findings shed light on how mammals evolved.
  • iconFecal excretion of PFAS by pets
    Per- and polyfluoroalkyl substances (PFAS) are used in a wide range of consumer products, from pizza boxes to carpets to non-stick cookware. Therefore, it's not surprising that these water- and stain-repelling substances are ubiquitous in the environment. Now, researchers report that cats and dogs excrete some PFAS in their feces at levels that suggest exposures above the minimum risk level, which could also have implications for the pets' owners.
  • iconImproving assessments of an endangered lion population in India
    An alternative method for monitoring endangered lions in India could improve estimates of their abundance and help inform conservation policy and management decisions.
  • iconCamera trap study captures Sumatran tigers, clouded leopards, other rare beasts
    Scientists deployed motion-sensitive camera traps across a 50-square-mile swath of Bukit Barisan Selatan National Park in southern Sumatra and, over the course of eight years, recorded the haunts and habits of dozens of species, including the Sumatran tiger and other rare and endangered wildlife. Their observations offer insight into how abundant these species are and show how smaller creatures avoid being eaten by tigers and other carnivores.

    Cats who suffered burns and smoke inhalation in recent California wildfires also had a high incidence of heart problems, according to a new study.
  • iconCat food mystery foils diet study
    How a study aimed at assessing the wildlife impacts of domestic cats was foiled by the mysterious ingredients of cat food.
  • iconKeeping cats indoors could blunt adverse effects to wildlife
    A new study shows that hunting by house cats can have big effects on local animal populations because they kill more prey, in a given area, than similar-sized wild predators. This effect is mostly concentrated relatively close to a pet cat's home, since most of their movement was a 100-meter radius of their homes, usually encompassing a few of their neighborhood's yards on either side.
  • iconUnraveling the puzzle of Madagascar's forest cats
    Biologists have long wondered where Madagascar's mysterious wild cats came from. Now, new genetic evidence delivers an answer.
  • icon'Fatal attraction': Small carnivores drawn to kill sites, then ambushed by larger kin
    Researchers have discovered that large predators play a key yet unexpected role in keeping smaller predators and deer in check. Their 'fatal attraction' theory finds that smaller predators are drawn to the kill sites of large predators by the promise of leftover scraps, but the scavengers may be killed themselves if their larger kin return for seconds.
  • iconSea otters, opossums and the surprising ways pathogens move from land to sea
    A parasite known only to be hosted in North America by the Virginia opossum is infecting sea otters along the West Coast. A new study elucidates the sometimes surprising and complex pathways infectious pathogens can move from land to sea to sea otter.

    Neuroscientists describe how the common Toxoplasma gondii parasite prompts the loss of inhibitory signaling in the brain by altering the behavior of nearby cells called microglia.
  • iconCanada lynx disappearing from Washington state
    Canada lynx are losing ground in Washington state, even as federal officials are taking steps to remove the species' threatened status under the Endangered Species Act. A massive monitoring study has found the big cat on only about 20% of its potential habitat in the state.
  • iconQuestionnaire survey identifies potential separation-related problems in cats
    The first questionnaire survey to identify possible separation-related problems in cats found 13.5 percent of all sampled cats displayed potential issues during their owner's absence, according to a new study.
  • iconConservation research on lynx
    Scientists have discovered that selected anti-oxidative enzymes, especially the enzyme superoxide dismutase (SOD2), may play an important role to maintain the unusual longevity of the corpus luteum in lynxes. It is highly likely that SOD2 not only detoxifies the reactive oxygen radicals in the cells, but also inhibits programmed cell death.
  • iconStress in parents of children with autism: Pets may help
    While current events have increased stress for all families, parents of children with autism report higher levels of stress on average than parents of typically developing kids. Feeling overwhelmed and overburdened by various responsibilities, some parents turn to pets as a source of comfort and support.
  • iconThousands of miles of planned Asian roads threaten the heart of tiger habitat
    Nearly 15,000 miles of new Asian roads will be built in tiger habitat by mid-century, deepening the big cat's extinction risk and highlighting the need for bold new conservation measures now, according to a new study.
  • iconCoronavirus structure clue to high infection rate
    Researchers studying the structure of the virus that causes COVID-19 have found a unique feature that could explain why it is so transmissible between people.
  • iconHow a mint became catnip
    Catmint -- or catnip -- is well-known for its intoxicating effect on cats. The odor responsible for the cats' strange behavior is nepetalactone, a volatile iridoid. Researchers have now found that the ability to produce iridoids had already been lost in ancestors of catmint. Hence, nepetalactone biosynthesis is the result of 'repeated evolution.' However, nepetalactone differs considerably from other iridoids with regards to its chemical structure and properties, and most likely its ecological functions.
  • iconStudy confirms cats can become infected with and may transmit COVID-19 to other cats
    Scientists report that in the laboratory, cats can readily become infected with SARS-CoV-2, the virus that causes COVID-19, and may be able to pass the virus to other cats.
