In order to avoid predators, scarlet kingsnakes in North Carolina have evolved to more closely resemble a poisonous lookalike no longer found in the area

It's not easy to study a whale vagina. But it is necessary. Right now, penises get far more attention than vaginas in the science world. (It's also apparent in the museum scene, too—sadly, today, there's no vagina equivalent to rival the Icelandic Phallocological Museum).

Receding glaciers at the end of the last ice age led to the flightless birds' move to the Crozet Islands

Life is tough if you’re a northern quoll (Dasyurus hallucatus). These rare, cat-sized Australian marsupials don’t have very long life spans—especially males, which tend to die after their first mating experience when less than a year old.

I have a prediction. There is a scientific hypothesis, formulated over 20 years ago, that we will one day look back on, when the evidence is in, and say “Of course that was right!

Is de-extinction a real possibility?

Crocodiles, alligators and gharials are the modern members of a far grander, far more diverse clade of archosaurian reptiles termed Crocodylomorpha.

California Chrome lacks a prestigious pedigree, but bears genes that make him born to run

While on a family holiday recently I visited Dan yr Ogof, the famous National Show Cave for Wales. Besides being interesting for the expected geological and speleological reasons, Dan yr Ogof is set within landscaped gardens that, bizarrely, feature one of Europe's largest `dinosaur parks'.

“It’s a strange world. Let’s keep it that way.”—Warren Ellis You can find some pretty weird things when you go poking around in holes in remote parts of the globe.

A juvenile tick trapped in a 15-million- to 20-million-year-old piece of amber contains a bacterium that could be the oldest documented ancestor of the microbe that causes Lyme disease

Sometimes research into one question reveals the answer to another. In July 2012 Catherine Hughes and Julie Broken-Brow, students at the University of Queensland in Australia, were in Papua New Guinea studying how the region’s tiny microbats responded to sustainable logging of their forest homes.
