An international consortium involving over 50 institutions has announced an ambitious project to assemble high-quality genome sequences of all 66,000 vertebrate species on Earth, including all mammals, birds, reptiles, amphibians, and fish. With an estimated total cost of $600 million dollars, it’s a project of biblical proportions. Continue reading Plan to Build a Genetic Noah’s Ark Includes a Staggering 66,000 Species
No other member of the animal kingdom can ace an algebra test or write an A+ essay. But that doesn’t mean other species aren’t highly intelligent. Several members of the animal kingdom have impress cognitive chops and cerebral skills.
The early 2000s were a great time to study amphibians in Panama. At night, dozens of species sang out in chorus while researchers measured and photographed frogafter frog, often hiking to remote sites hours from the nearest road. Jamie Voyles and Cori Richards-Zawacki were both graduate students at the time, just at the start of their scientific careers, and Panama’s amphibians offered a plethora of research possibilities.

Ever since the 19th century, when disease was first linked to sewage-contaminated water, humans have gone to great lengths to escape their own filth. Meanwhile, animals have gone on reveling in the stuff—eating it, strategically dropping it, flinging it around just to pass the time, etc. Same goes for mud, piss, vomit, blood and rotting carcasses of every make and vintage. Most creatures just don’t have our hang-ups. Continue reading What’s the Filthiest Animal?
There’s something about the blind Mexican cavefish that will make you quite jealous: To survive and thrive, they require just two hours of sleep each night; no more, no less. Imagine everything you could do with those extra six hours.

However wondrously varied the animal kingdom might be, on a species-level its residents tend to look more similar than not—at least, from a human perspective.

Does the thought of leaving your pet behind in an evacuation keep you up at night? If so, you’re not alone. A recent paper in the American Journal of Public Healthhighlights how neglecting steps for evacuating animals, thereby forcing people to leave their pets behind, can have serious public health consequences for the pet owners—and for everybody else.
