- Government scientists link directly, for the first time, a boost in warming at Earth’s surface to increasing levels of carbon dioxide. Much of that gas has been released by human activities, such as coal burning and gas-burning vehicles.
- A new study of one of the deadliest U.S. outbreaks of tornadoes sees a possible role for smoke. In this analysis, the smoke had come from fires burning in Central America.
- A half-century search for samples of Earth’s most abundant mineral has ended. This stuff forms only deep in the rocky layer surrounding our planet’s core. But scientists found bits of it in a meteorite that fell in 1879. And finally, this bridgmanite gets a name.
- Warming temperatures will lead to 50 percent more lightning strikes across the 48 U.S. states in the next century, researchers report. That increase could lead to more warming, more fires and even more deaths.
- Scientists have probed the fossilized remains of an ancient jellyfish. It reveals a bizarre sequence of events that led to its preservation 310 million years ago.
- Last year, scientists drilled 800 meters (roughly a half mile) down through ice to reach a pitch-black Antarctic lake. They now report that lake hosts a thriving community of one-celled microbes.
- Enormous meteorites appear to have slammed into Earth several times early in its history. Each mega-smashup would have boiled off oceans and obliterated any bit of life.
- Scientists have compressed diamonds more than ever before. Their carbon may give clues to what conditions might be like deep within planets way beyond our solar system.
- This late-Jurassic dino was also a bird. Its ample coat of feathers emerged before any need for flight.
