A circular economy for sustainable resources
Scientists proposed a new economic strategy to distribute global rare earth element reserves more sustainably.
How quickly can forests recover from wildfires?
Scientists modeled forest productivity before and after wildfires. They found that plant regrowth depended on the type of biome and how much…
When did freshwater appear on Earth?
Geologists found chemical ratios in ancient minerals that suggested Earth had freshwater 550 million years after it formed.
Is groundwater heating up?
Researchers modeled groundwater temperature trends from 2000 to 2100. They estimated that groundwater could warm by up to 3.5°C over the…
Is Earth safe from nearby exploding stars?
Scientists used an Earth system model to test how radiation from a nearby supernova would affect life on our planet. They found that the…
Melting glaciers release methane
Geologists studied gas fluxes from groundwater springs uncovered by melting Arctic glaciers. They estimated that these springs release over…
Volcanism warmed past Earth
Geologists dated a global warming event about 180 million years ago. They found it lasted between 169,000 and 417,000 years and was linked…
New way to find geothermal energy
Scientists used an exploration approach developed by the oil industry to track down geothermal energy sources.
Methane-munching microbes modify the seafloor
Researchers showed that methane-eating bacteria acidify their surroundings and dissolve carbonate rocks on the seafloor.
