The Golden Poison Frog

Despite its diminutive size, the golden poison frog is one of the deadliest creatures in the world. Native to Columbia, the poisonous—but not venomous—frog contains enough of the rare neurotoxin batrachotoxin to kill 10 humans. Indigenous peoples use the toxin on the tips of poison darts and arrows. The intelligent frogs are seemingly unafraid of potential predators. They do not produce the toxin themselves, and lose their toxicity in captivity. Where, then, do they acquire the toxin? More...

First Issue of the New-York Daily Times, now The New York Times, Is Printed (1851)

Originally sold for a penny a copy, the New-York Daily Times was founded by journalist and politician Henry Jarvis Raymond in 1851 and has been controlled by the Ochs-Sulzberger family since 1896. The paper shortened its name to The New York Times in 1857. Perhaps the most respected newspaper in the world, it has been awarded more Pulitzer Prizes than any other. In 2006, the newspaper announced that it would save how much money by narrowing its page width by 1.5 inches (4 cm)? More...

Fiestas Patrias (2017)

Fiestas Patrias is the national two-day holiday in Chile celebrating Independence Day, September 18, and Army Day, September 19. In the days preceding the holiday, fondas (fairs) pop up throughout Chile, and it is a popular time for Chilean rodeo. Huasos (cowboys) compete against one another by attempting to pin a calf against the wall of the medialuna, or arena, with their horse, and are awarded points based on which part of the horse is touching the calf. Because September marks the beginning of spring in Chile, Fiestas Patrias is also a popular occasion for kite flying. More...

Why Van Gogh's Flowers Are Changing Colors

When conservation work on Flowers in a Blue Vase by Vincent van Gogh was begun in 2009, conservators noticed that the vibrant yellow paint used for some flowers in the painting had become greyish and cracked. Scientists who investigated the change say it's due to a never-before-seen chemical reaction between the pigment, called cadmium yellow, and a protective varnish added well after the painting was finished. Using X-rays on a microscopic sample of the painting, scientists found the compound causing the discoloration—cadmium oxalate—in a micrometer-thin layer between the paint and the varnish. More...
