State lines are one way to picture the US, but natural history provides another – one that shows the ancient and living connections running across the landscape.

Some salamanders begin their spring migration in the deep cold. New field research shows how they stay active without freezing.
Redwoods grow in networks that house unique communities of plants and animals high in the air. They offer life lessons about adapting over time.
Axolotls are amphibians known for their ability to regrow their organs, including their brains. New research clarifies their regeneration process.
The discovery shakes up what scientists thought they knew about salamander evolution.
The Bsal fungus is not yet here in North America, or any place in the Western Hemisphere, but there is concern that the pet trade is the most likely route for introduction here.
If albanerpetontids were around today, they’d easily fit in your hand. And although their bones are found all over the world, these unique amphibians eluded experts for a long time.
Local adaptation allows plants and animals to thrive in a diversity of places. Sometimes adaptation sharpens patterns of where organisms live, but 85% of the time, it creates a more homogeneous world.
People sometimes release pets into the wild, resulting in biological invasions.
Chytrid fungus has caused a global “amphibian apocalypse,” killing frogs worldwide. Now some appear to be evolving resistance – but a closely related fungus threatens newts and salamanders.
Nature has created some of the strongest glues with properties we could use – if we understood how they worked.
A new project hopes to drill through the Earth’s crust for the first time. But what beasties lurk deep beneath our feet?
Newts are unique within the salamander family for the way they regrow limbs. And along with fossils are giving clues to a unique ability to regenerate.
Metoposaurus algarvensis, aka toilet jaws, was all over our early ancestors. The thing that got us off the hook? A big hot interception 200m years ago.
Biologists in the US have discovered the number and physical condition of woodland salamanders can be linked to a forest’s…
Damage to vital organs, the spinal cord, or limbs can have an enormous impact on our ability to move, function – and even live. But imagine if you could restore these tissues back to their original condition…
