Discovered This Day: Radium
“In 1898, Polish-French scientist Marie Sklodowska Curie discovered the radioactive element radium while experimenting with pitchblende, a common uranium ore. She had observed that this ore was more radioactive than refined uranium. This indicated that there must be another element, even more radioactive than uranium, mixed in with this ore.
During the years between 1899 and 1902, Marie Curie dissolved, filtered and repeatedly crystallized nearly three tons of pitchblende. The goal of that work was a refined sample of the element - the yield was about 0.1 gram. This was enough for spectroscopic examination, and to determine the exact atomic weight of radium. This discovery, along with the element polonium, earned her a second Nobel Prize in 1911.” From Today In Science History

Preventing The Next Ice Age
Powerful simulations on the world's most advanced computer climate models lend strong support to the radical idea that human-induced climate change began not 200 years ago, but thousands of years ago with the onset of large-scale agriculture in Asia and extensive deforestation in Europe.
What's more, according to the same computer simulations, the cumulative effect of thousands of years of human influence on climate is preventing the world from entering a new glacial age, altering a clockwork rhythm of periodic cooling of the planet that extends back more than a million years.Using climatic archives such as 850,000-year-old ice core records from Antarctica, scientists are teasing out evidence of past greenhouse gases in the form of fossil air trapped in the ice. That ancient air, say Vavrus and Kutzbach, contains the unmistakable signature of increased levels of atmospheric methane and carbon dioxide beginning thousands of years before the industrial age.
"Between 5,000 and 8,000 years ago, both methane and carbon dioxide started an upward trend, unlike during previous interglacial periods," explains Kutzbach. Indeed, Ruddiman has shown that during the latter stages of six previous interglacials, greenhouse gases trended downward, not upward. Thus, the accumulation of greenhouse gases over the past few thousands of years, the Wisconsin-Virginia team argue, is very likely forestalling the onset of a new glacial cycle, such as have occurred at regular 100,000-year intervals during the last million years. Each glacial period has been paced by regular and predictable changes in the orbit of the Earth known as Milankovitch cycles, a mechanism thought to kick start glacial cycles.
"We're at a very favorable state right now for increased glaciation," says Kutzbach. "Nature is favoring it at this time in orbital cycles, and if humans weren't in the picture it would probably be happening today." Read the press release

WeirdWorld by Moench & Ploog
“Weirdworld was set in a dimension of magic not unlike Middle-earth from The Lord of the Rings. The protagonists were two elves: Tyndall and Velanna , both from the floating ring-shaped island of Klarn, and an irascible dwarf dubbed Mud-Butt (because he tended to land on his backside in a quarrel)." link
Weirdworld (later changed to “Warriors of The Shadow Rhelm”) was created by Doug Moench and Mike Ploog and first appeared in the black and white magazine Marvel Super Action #1 (January, 1976). This tale from Marvel Preimere #28 (1977) is the 2nd of 1st three tales illustrated by Ploog, and the only one inked by Alex Nino. The whiplash-inducing ending suggests that the creators had their original page count for the story chopped at the last minute.
Weirdworld kicked around a variety of Marvel titles between 1976 and 1982, and one of the swamp serpents even made a cameo in X-men First Class II (2008). The three part mini-series in Marvel Super Special, illustrated by John Buscema, was heralded at the time for its use of full color paintings throughout. Although Ploog and Nino have very different art styles, they mesh surprisingly well in this story. This is a series that would benefit from a good collection, with an added tale or two to finish up the story.
Tim Perkins has a nice overview of the series and features some of his own unpublished “Weirdworld” art.

1933: 1st Full-Length Animated Film Premieres
In 1937, Snow White and the Seven Dwarfs, Walt Disney's first full-length (83 minutes), animated film opened in Los Angeles, California. Using the story adapted from Brothers Grimms' Fairy Tales, it was the first commercially successful film of its kind.
Taking two years and $1.5 million to create, it was released for its premiere during Christmas of 1937. Disney had to mortgage his house to pay for the film's production. This followed within a span of just 12 years since the first black and white talking Mickey Mouse in Steamboat Willie (1928). link
From 1933, The Fleischer Bros. present Betty Boop's "Snow White" featuring Cab Calloway:
