Depleting oxygen and rising hydrogen sulfide levels in the oceans may have been responsible for one of Earth’s most significant mass extinctions more than 350 million years ago, a new study finds. The changes were likely driven by rising sea levels and have some spooky parallels to conditions seen today. Researchers studied samples of black … Read more
As climate change transforms our world, the impacts will be felt unequally, with some animals struggling to survive and others finding ways to overcome the resulting challenges. This phenomenon is increasingly described as the “winners and losers under climate change,” said Giovanni Strona (opens in new tab), an ecologist and former associate professor at the … Read more
There is a frozen soup of viruses, bacteria and fungal spores lurking beneath the frigid Arctic soil. Unlike the icy leftovers in the back of your freezer, some of these microbes haven’t interacted with a cell since well before ancient Egyptians built the Pyramids of Giza. As climate change continues to cook the planet, however, … Read more
Sea levels are likely rising faster than previously thought, meaning low-lying coastal cities in the U.S. could flood far more regularly in the coming decades, a NASA study has revealed. According to the study, which analyzed three decades of satellite observations, by 2050, sea levels along the coastlines of the contiguous U.S. could rise as … Read more
Scientists have just announced a breakthrough in nuclear fusion ignition: For the first time the heart of a powerful fusion reactor has briefly generated more energy than was put into it. But experts are urging caution, saying that the breakthrough, while hugely significant, is still a long way from safe, limitless nuclear energy. On Tuesday (Dec. 13), physicists at … Read more
A river longer than England’s Thames flows beneath the Antarctic ice sheet, draining an area the size of France and Germany combined, new research reveals. This under-ice river was discovered using ice-penetrating radar mounted on aircraft. In a series of aerial surveys, researchers discovered a river system snaking 285 miles (460 kilometers) and draining into … Read more
When lightning flashes above, plants on the ground may respond in kind. Scientists have long been aware that plants and trees can emit small, visible electric discharges from the tips of their leaves when the plants are trapped beneath the electrical fields generated by thunderstorms high overhead. These discharges, known as coronas, are sometimes visible … Read more
Hydrogen and natural gas are among the alternative fuels starting to get more attention as car companies work to reduce emissions. But Audi is exploring another option that you may not have heard much about yet: e-fuels. The German automaker, which aims to develop synthetically engineered e-fuels as a viable alternative to gasoline and diesel, … Read more
Ancient microbial life on Mars could have destroyed the planet’s atmosphere through climate change, which ultimately led to its extinction, new research has suggested. The new theory comes from a climate modeling study that simulated hydrogen-consuming, methane-producing microbes living on Mars roughly 3.7 billion years ago. At the time, atmospheric conditions were similar to those … Read more
DNA from ancient microorganisms, some of which dates back to roughly 1 million years ago, has been discovered beneath the seafloor in Antarctica. The DNA is the oldest ever discovered from seafloor sediments, a new study shows. Scientists accidentally collected the unusual genetic samples, known as sedimentary ancient DNA or sedaDNA, up to 584 feet … Read more
