New satellite may make flood prediction easier
A satellite on schedule to launch in 2021 could offer a more comprehensive look at flooding in vulnerable, under-studied parts of the world, including much of Africa, South America and Indonesia, a new study has found.
Read more'Treasure trove' of earthquake clues could be unearthed by wavy new technique
Geologists have improved upon methods to map seabed rocks, helping us better understand underwater earthquakes and the tsunamis they can cause.
Read moreMicroplastics in the Great Lakes: Becoming benthic
From the Great Pacific garbage patch to inland rivers, plastics are among the most widespread contaminants on Earth. Microplastics — particles of plastic smaller than five millimeters — are especially pervasive. As they build up in Earth's waters, microplastics are also becoming a permanent part of the planet's sedimentary layers.

The ancient Incan sanctuary of Machu Picchu is considered one of humanity's greatest architectural achievements. Built in a remote Andean setting atop a narrow ridge high above a precipitous river canyon, the site is renowned for its perfect integration with the spectacular landscape. But the sanctuary's location has long puzzled scientists: Why did the Incas build their masterpiece in such an inaccessible place?
Croc-like carnivores terrorized Triassic dinosaurs in southern Africa 210 million years ago
Giant, predatory croc-like animals that lived during the Triassic period in southern Africa preyed on early dinosaurs and mammal relatives 210 million years ago. These predators, known as 'rauisuchians' preyed on early herbivore dinosaurs and their mammal relatives living at the time.
Read moreNew evidence of the Sahara's age
The Sahara Desert is vast, generously dusty, and surprisingly shy about its age. New research looking into what appears to be dust that the Sahara blew over to the Canary Islands is providing the first direct evidence from dry land that the age of the Sahara matches that found in deep-sea sediments: at least 4.6 million years old.

For iconic landscapes such as Grand Canyon or the Appalachian Mountains, geological features are an integral part of their appeal. Yet despite the seeming permanence of cliffs, caves, fossils, and other geological highlights, these features are surprisingly vulnerable to damage or destruction.
