    These fish could be harbingers of a major human health crisis

    Bad news, everyone. Researchers have discovered that 15% of the coral trout living in Australia's great Barrier Reef are suffering from what's been described as a scalier version of melanoma, a deadly form of skin cancer.
    Are bites from vampire bats making people resistant to rabies?
    ...
    The disease, which is commonly transmitted by bats, is almost always fatal. But a recent study conducted in Peru is suggesting that native people there may have developed an immunity to the virus by getting bitten by vampire bats. If true, the discovery could have serious implications to the development of vaccines — and even a cure.

    Kitty Cameras Find U.S. House Cats Killing More Prey Than Previously Known
    ...
    The study found that only 30 percent of the 74 million U.S. house cats prey on smaller animals, but this 30 percent is taking part in much more outdoor hunting than previously thought. According to study leader Kerrie Anne Loyd, previous numbers were likely lower because "they didn't include the animals that cats ate or left behind."

    While the study didn't give a total number of prey killed by the house cats, about 49 percent of critters killed by house cats were left for dead, 30 percent were eaten and just under 25 percent were brought home.

    Single mutation keeps racehorses in the money
    Single change affects their ability to trot at high speed.
    ...
    They found it was present at a high rate in horses bred for harness racing. In fact, all American Standardbred trotters had two copies of the mutation (the presence of only a single copy appears to have no effect, meaning the mutation is recessive).

    A more interesting natural experiment occurred in the population of Swedish harness racers. And here, the mutation's presence was correlated with something you don't often see measured in a genetics paper: money. The mutation was linked to higher race performance, breeding values, and increased prize earnings over a horse's career.

    A new species of bee that survives solely by invading other beehives
    It would now appear that cuckoo birds are not the only animal that has the nasty habit of laying its eggs in another animal's nest. A newly discovered species of bee has been observed to invade the nests of other bees while they're out collecting pollen. It's during this opportune time that the female members of these newly dubbed "cuckoo bees" lay their eggs in the hive. And because invader eggs hatch early, the immature bees are able to get rid of the host bee eggs — leaving the pollen and nectar reserves for themselves.
    Scientists have solved the 200-year-old mystery of this “monstrous” creature
    For almost two hundred years, Cerataspis monstrosa has been turning up in the guts of everything from dolphins to tuna. But for as widely known as this larval creature is, its adult counterpart has managed to remain a mystery.

    These birds hold funerals for their dead
    ...
    Researchers at UC Davis have observed this funereal behavior in western scrub jays. When one bird spots a dead jay on the ground, it stops what it was doing and starts sending out loud alarm calls. The calls bring in jays from all over, who gather around the body and continue sending out the alarm calls so that as many jays as possible show up near the dead body.

    Pregnant males and pseudopenises: complex sex in the animal kingdom
    Think sex and gender are simple? Nature says otherwise.

    ...
    The spotted hyena may have one of the most arresting sexual incongruities in the animal kingdom. Female hyenas possess what scientists call "pseudopenises," since they so closely mimic male penises. These female organs are fully erectile, can be up to seven inches long, and are accompanied by a “pseudoscrotum.” Stranger still, a female hyena must urinate, copulate, and give birth through her pseudopenis. No wonder that, for centuries, people thought hyenas were hermaphrodites—watching a mom with a large penis nurse her babies can be a little confusing.

    Killer whales need their mamas to look after them… even as adults
    Despite their fearsome nickname, orcas might actually be among the animal kingdom's biggest mama's boys. Males rely on their mothers to keep them alive well into their adulthood — and that might help explain the evolution of menopause.

    Enslaved worker ants fight back through acts of sabotage
    New research from Gutenberg University Mainz in Germany shows that enslaved ants conduct their own form of civil disobedience, by neglecting and killing the offspring of their oppressors. And by doing so, the ants may be preventing their comrades outside the nest from being enslaved themselves.

    One Way That Bird Brains Could Be Superior to Mammal Brains
    Mammals are unique in that they're the only animals whose brains feature a neocortex — a recently evolved structure that's responsible for higher order functioning like conscious thought, sensory perception, spatial reasoning, and language.
    But now, scientists working at the University of Chicago have confirmed that birds have their own version of the neocortex — one that may actually give them certain cognitive advantages over mammals.
