A trove of footage from early U.S. nuclear weapons tests has just been declassified and uploaded to YouTube.
The film release was part of a project headed by Lawrence Livermore National Laboratory (LLNL) weapons physicist Greg Spriggs which aimed to digitize and preserve thousands of films documenting the nation’s nuclear history. The endeavor required an all-hands-on deck approach from archivists, film experts and software engineers, but the team says that this digitized d ...read more

Researchers who want to study the nature of Earth’s original crust find themselves between a rock and a hard place: Our planet’s top layer is constantly wearing down in one spot and building up in another, continents colliding or slip-sliding past each other in the great mosh pit of plate tectonics. You might have figured none of the early crust was even still around. New research shows you would have f ...read more

Natural variability in atmospheric conditions could account for as much as half of the recent decline in Arctic sea ice, according to a new study.
While the masses of ice that float atop the planet have been in steady decline over the past few decades, scientists haven’t been able to say how much of the losses are attributable to human-driven climate change and how much is simply the result of periodic swings in climate conditions. While the scientific c ...read more

We know that dogs have a guilty look, but can they actually be guilty? Well, according to this study, the answer is… kind of. Here, researchers show that dogs are capable of “deceptive-like behavior.” In a set of experiments, dogs tended to lead a human “competitor” away from food when that human would keep it for himself. However, the same dogs happily lead their “cooperative” owner to the ...read more
