How do you determine whether a creature is immortal? In this animated video, Radiolab host Robert Krulwich explains why, after observing hydra for just a few years, one researcher suggested that the animals might live startlingly long lives.
Krulwich Wonders, the superlative science blog maintained for the last four years by Robert Krulwich (of NPR and Radiolab fame), will soon be no more.
Here's a fun experiment to try next time you find yourself in an open field. Close your eyes (or wear a blindfold) and set off walking, taking care to walk in as straight a line as possible. Have a buddy monitor your route (and warn you of obstacles). Sounds simple enough, right? Turns out it's harder than you think.
If you'd asked Emily Dickenson this question, she would have told you that "The brain is wider than the sky / For, put them side by side / The one the other will include / With ease, and you beside."
Remember the Lord Howe Island stick insect, that massive "tree lobster" researchers thought had been extinct for decades? Rohan Cleave of the Melbourne Zoo has filmed one of these arthropod giants emerging from an egg. The insect spends six months incubating — when it's time to leave the egg, the animal literally (and…
In 1918, a battered British supply ship was forced to run aground off the coast of Lord Howe Island, a volcanic remnant located hundreds of miles off Australia's eastern seaboard. There, the ship's crew was received by the island's famous Dryococelus australis, a positively massive, hand-sized species of stick insect…
When the Nazis invaded Copenhagen in 1940, physicist Niels Bohr was in possession of two Nobel Prize medals. But they were not his medals. The first belonged to Max von Laue, winner of the 1914 Prize for physics, the second to James Franck, the physics winner in 1925.
It's been a big year for the space sciences. The first privately-held spacecraft orbited our world, the blackest material in history was created, researchers expanded the list of possible sources of life threefold; and that was just in December.
