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, […]

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 […]

Primary forests are crucial for biodiversity conservation and store high quantities of carbon in biomass, therefore helping to mitigate climate change.

Cross-section view of Austrocedrus chilensis wood in the Andes of northern Patagonia, Argentina. This species is abundant in the xeric forest-steppe ecotone, where periodic massive mortality events have been documented in relation to extreme droughts in Patagonia during the 20th century.
