ANIMATION While there are efforts to reinforce its beaches and marshes, some of Barataria Bay is slowly slipping away Sandwiched between the Mississippi River and Bayou Lafourche, the Barataria Bay in Louisiana is a latticework of shrinking marsh, swamp, and islands. Few other coastlines in the Mississippi River Delta—or anywhere […]
January 5, 2021 In spring and summer, conditions are often just right for populations of the plant-like organisms explode into enormous blooms. The Goldilocks zone typically refers to the habitable area around a star where conditions are right for the existence of liquid water and possibly life. But on Earth, […]
ANIMATION After two years of quiet, Kilauea, Hawaii’s youngest and most active volcano, is erupting again. In the early days of the volcano’s latest eruption, water that had pooled in the volcano’s summit crater (Halema‘uma‘u) since July 2019 was replaced by a lava lake. The water boiled off on December 20, 2020, […]
Overview of the study area and the schematic illustration of interaction of fault motion and the seafloor subsidence. Credit: University of Tsukuba University of Tsukuba researchers have developed a state-of-the-art model, which has revealed major complexity in rupture processes even in simple oceanic faults. Researchers from the University of Tsukuba […]
August 15, 2020. (Click here for wide, high-resolution image.) If you accidentally stumbled upon the town of Huacachina, you might think it is a mirage. Huacachina is centered around a lagoon lined with lush vegetation—all located in the driest desert in the world. Snuggled between the biggest sand dunes in […]

The first large-scale study of the risks that countries face from dependence on water, energy, and land resources has found that globalization may be decreasing, rather than increasing, the security of global supply chains. Countries meet their needs for goods and services through domestic production and international trade. As a […]
The proximity of hot springs to early settlements have led researchers to wonder if early humans used hot springs as a cooking resource long before fire. Credit: Tom Björklund Scientists have found evidence of hot springs near sites where ancient hominids settled, long before the control of fire. Some of […]
