Why I’m Not Sorry to See the Space Shuttle End
I have to say, when I think about the end of the Space Shuttle program, I'm really not that sorry to see it come to a close

A Delayed Tyrannosaurus Showdown
In 1913, paleontologists at the American Museum of Natural History made plans for what would have been a spectacular reconstruction of a prehistoric battle. Too bad that their plans did not come to fruition.Tyrannosaurus rex—the most celebrated dinosaur of all time—made its debut at the AMNH. The f...

The Myth of the Eight-Spiked Stegosaurus
Everybody knows that Stegosaurus had four tail spikes. The formidable weapons this odd dinosaur sported were some of its most prominent features. Yet, when Stegosaurus was new to science, it seemed as if this dinosaur bristled with even more spikes. In 1891, the first full skeletal drawing of Stegosaurus ungulatus was created under the direction [...]

Bringing Dinosaurs Up to Speed
Dinosaurs are ambassadors of paleontology. Much to the frustration of scientists who study plants, invertebrates, and even fossil mammals, the word "paleontologist" is closely associated with the image of scruffy researchers digging around for dinosaur bones. Despite the popularity of dinosaurs, th...

A 1980s Look at Smithsonian Dinosaurs
I thought that I had seen just about every major dinosaur documentary from the 1980s, but I just found out that I missed at least one: the Smithsonian Video Collection's Dinosaurs. It was one of many programs—like A&E's miniseries Dinosaur!—that were inspired by deep changes to what we thought ...

How Tyrannosaurus Lost a Finger
Everybody knows that Tyrannosaurus had small arms tipped in only two fingers. The relatively small arms of the Late Cretaceous predator are part of its charm. When paleontologist Henry Fairfield Osborn described Tyrannosaurus in 1905, however, the fingers and forearm of the dinosaur were missing. E...

When Dinosaurs Were New
I spent Sunday morning among the dinosaurs of Smithsonian's National Museum of Natural History. The skeletons of the prehistoric creatures stood nearly shoulder to shoulder—the Tyrannosaurus appeared to snarl at a nearby Triceratops, and an Allosaurus stood dangerously close to the business-end of...

Will the Dinosaurs Return?
When the American Museum of Natural History's paleontologist William Diller Matthew published his book Dinosaurs in 1915, no one understood how the famous Mesozoic creatures originated or went extinct. Both the beginning and end of the "Age of Dinosaurs" were mysterious. Yet, tucked away in a foot...

Is There A "Homer Simpson Effect" Among Scientists?
Despite decades of progress for women in science (and some arguments that no more is needed), the playing field still isn't level. But do all the advantages men get result in them thinking more highly of their expertise than female scientists do? Three researchers, including D. Carolina Useche at t...

Five Reasons Anti-Evolution Measures are a Bad Idea
In 1925, John Scopes, a high school biology teacher, was put on trial in Tennessee for having the audacity to teach evolution to his students. In the 21st century, teachers don't have to worry about being arrested for teaching this fundamental topic in science, and the Supreme Court declared teachi...

Great Depression Had Little Effect on Death Rates
There's this somewhat counter-intuitive idea that economic downturns are good for your health. You might expect the privation and malnutrition inherent in such times would take a toll. But during the Great Depression, mortality rates fell. And since that time, the idea that recessions are a net-pos...

The Lost Naturalist: A 163-Year-Old Australian Mystery
When I was preparing to visit friends in Australia a few years ago, I read a book about all the ways the continent would kill you. The entry on scorpions, I remember, stood out because it said not to worry about them---their stings only hurt.I was reminded of this while reading a story from Austral...

Dinosaur Sighting: Vintage Stegosaurus
Like many fossils fans, I quite enjoy picking apart bad restorations of dinosaurs, but I must admit that I have a soft spot for the 20th century image of drab, slow, stupid dinosaurs. Those were the dinosaurs I first encountered at museums and school libraries—just before the "Dinosaur Renaissance...

Creating an Allosaurus Feast
I feel a little sorry that I said Allosaurus had one of the dullest names in paleontology yesterday. It's not the dinosaur's fault that Othniel Charles Marsh gave it the unimaginative title of "different reptile." Had Marsh seen the complete skeleton when he coined the name, perhaps he would have ...

Always Brontosaurus to Me
During the latter half of the 1980s, when I was just becoming acquainted with dinosaurs, "Brontosaurus" was just on its way out. A few of my books depicted the lumbering dinosaur, and a few museums still had the wrong heads on their skeletons, but the images of slow, stupid Brontosaurus were slowl...
