I have a couple shelves of my books I need to clear out. You have to buy holiday gifts. We need to talk!
If you’d like to get an autographed copy of one of my books, please check out the Amazon links below. They’re all in good or like-new condition.
Amazon’s gotten a little buggy when it comes to presenting used books, but these links should take you to a collectible offer marked “Carl Zimmer–Author.” First come, first serve! Continue reading “Friday’s Elk, December 13, 2017”

The 57-million-year-old fossil is both fearsome and comical: a long-beaked penguin that stood 5 feet 7 inches tall and weighed about 220 pounds.
“It was as tall as a medium-sized man,” said Gerald Mayr, a paleontologist at the Senckenberg Research Institute in Frankfurt, Germany, and lead author of a report in Nature Communications on Tuesday announcing the discovery.
By comparison, the tallest living species, the emperor penguin, reaches about four feet in height. Kumimanu biceae, as the fossil was named, would have towered above the emperor, and above just about all other known ancient penguins.

When you drive toward an intersection, the sight of the light turning red will (or should) make you step on the brake. This action happens thanks to a chain of events inside your head.
Your eyes relay signals to the visual centers in the back of your brain. After those signals get processed, they travel along a pathway to another region, the premotor cortex, where the brain plans movements.
Now, imagine that you had a device implanted in your brain that could shortcut the pathway and “inject” information straight into your premotor cortex.

Greetings. I hope all American readers had a happy Thanksgiving. A sudden arrival of stuffing and turkey slowed down my email newsletter production, and so I have a bit to catch up on here.
First off, the columns. Continue reading “Friday’s Elk, December 2, 2017”

It’s hard to see what’s so special about a scallop. It looks a lot like a clam, mussel or any other bivalve. Inside its hinged shell lurks a musclebound creature that’s best enjoyed seared in butter.
But there’s something more to this ubiquitous entree: the scallop sees its world with hundreds of eyes. Arrayed across the opening of its shell, the eyes glitter like an underwater necklace. Each sits at the tip of its own tentacle and can be extended beyond the rim of the shell.
While some invertebrate eyes can sense only light and dark, scientists have long suspected that scallops can make out images, perhaps even recognizing predators quickly enough to jet away to safety.
