European mammals will struggle under climate change

As temperatures on Earth rise, many animals have already begun migrating to more amenable climates, shifting their ranges. But not all animals will be able to relocate, according to a new study in the journal Diversity and Distributions.

Benchmarks: July 29, 1958: The Birth of NASA

Growing up in the suburbs of Washington, D.C., meant that my house was often frequented by guests who wanted to visit our nation’s capital. Without fail, this meant my family and I would be taking a trip to one of the Smithsonian’s most popular attractions, the National Air and Space Museum. I can’t count the number of times I visited the museum before I left for college, but it was a lot. Although glimpsing the museum’s collection of aircraft and spacecraft was cool at first, I would much rather have spent those afternoons wandering the halls of the National Museum of Natural History.

Cretaceous volcanic ash seeded U.S. oilfields

Petroleum and natural gas stores are often found amid rocks — particularly ashbeds — deposited during the Cretaceous, when dinosaurs roamed Earth and abundant volcanic arcs lined the edges of the continents.

Tracking Hurricane Harvey's freshwater plume

On Aug. 25, 2017, Hurricane Harvey made landfall along the Texas coast as an unexpected Category 4 storm, with maximum sustained winds of 209 kilometers per hour. After rapidly intensifying over the Gulf of Mexico, it hovered over southeastern Texas for days, slowly weakening as it dumped 68 trillion liters of water onto the land — more than three times the volume of the Great Salt Lake in Utah.

Down to Earth With: Highway paleontologist Shane Tucker

When roads are built in fossil-rich states, paleontologists sometimes follow the trucks and bulldozers to make sure that the buried treasures that construction crews occasionally uncover — namely, remnants of ancient animals and plants — get out of the ground safely and into a museum to be cataloged and studied.

Radium levels suggest Arctic Ocean chemistry is changing

Rising temperatures have already caused changes in the Arctic environment, like diminishing sea ice and thawing permafrost. Now, it appears that sea-ice loss could be throwing Arctic Ocean chemistry out of whack.

Hot tropics drove out ancient reptiles, but they came back

About 252 million years ago, massive volcanic eruptions in what is now Siberia rapidly warmed Earth, resulting in the end-Permian mass extinction that saw most terrestrial and marine species die off. It’s been thought that surviving reptiles and fish fled the hot tropics and didn’t return for millions of years. But according to new research, the tropical evacuation may not have lasted so long after all.

Earthquakes shaped ancient Greek culture

In ancient Greece, earthquakes frequently shook the ground and devastated cities and temples. But time after time, people built — and rebuilt — prominent structures near dangerous faults. How much the ancient Greeks knew about earthquakes and fault behavior is unclear. But in a new study in Proceedings of the Geologists’ Association, researchers suggest that the relationship between sacred sanctuaries and faults is more than coincidental, and that earthquakes may have had a previously underappreciated cultural significance to the ancient civilization.
