See these annular structures? They are 492 million years old and come from Wisconsin. Here are some more. Was there a severe shortage of beer coasters in Cambrian Wisconsin?
To look at a rock sponge, which usually has all the visual appeal of a potato, you would never guess that inside lies the Notre Dame of animal skeletons.
The tropical plant Genlisea is a tiny, homely rosette of simple green leaves. If you dig up its roots, you will find what look like an unremarkable bunch long, pale underground roots.
To a human, two billion years is an unfathomable interval. But that, a team of European, Gabonese, and American scientists now say, is how long ago a recently discovered hoard of fossils suggests Earth’s first big life evolved — large enough to see with the naked eye, and in a spectrum of forms that tease [...]..
Just how big is a giant squid? Not quite as big, perhaps, as you might think. This fabulous new graphic from the Deep Sea News crew and several other scientists represents *a lot* of research to find out the true largest sizes of 25 ocean creatures of giant repute...
There comes a depth at which even fish struggle to survive the titanic pressure. But that depth is only found at the few places on Earth that lie below 27,600 feet of water, where the weight of the water warps piscine proteins and crushes cells...
Author's note: This is the latest post in the Wonderful Things series. You can read more about this series here. One of the more under-appreciated and ingenious machines evolved by plants is the cavitation catapult of leptosporangiate ferns...
Today I have a small biology present for you courtesy of a new series of short videos produced by PBS Digital Studios and KQED San Francisco.
Bacteria propel themselves with corkscrew tails anchored in rotary motors. That may seem surprisingly mechanical for a microbe, but it is a system that has been wildly popular and conserved across billions of years of evolution...
The organisms that cause us untold suffering can also be astounding works of art, sculpted by evolution into elegant, deadly packages. Such is the case for the trypanosomes, the protists I discussed last time as the source of Chagas Disease, but which also cause sleeping sickness in Africa...
