Lake Natron: The caustic, blood-red lake in Tanzania that turns animals to 'stone'
Lake Natron is a soda lake in northern Tanzania with a volcanic geology that maintains the water's pH around 10.5, which is almost as caustic as ammonia. Some life-forms thrive there nevertheless.
Record-breaking piles of sargassum seaweed wash up on Caribbean beaches, with more on the way
Record amounts of sargassum are floating in the Caribbean Sea and ending up on beaches from Puerto Rico to Guyana — but scientists aren't sure why there's so much of it in the first place.
Earth's energy imbalance is rising much faster than scientists expected — and now researchers worry they might lose the means to figure out why
For reasons still unknown, Earth's energy imbalance is rising much faster than models can account for. Now, scientists are calling for long-term investment in monitoring capability, so that they can make informed predictions about climate change.
The closer a volcano is to erupting, the greener the trees around it look from space
Scientists have found a way to monitor volcanic carbon dioxide levels — one of the first signs a volcano might be about to blow — that doesn't involve trekking up a mountain.

The decline of key Atlantic currents is underway, and it's been flooding parts of the US for 20 years
New research has linked sea level rise and an increase in flooding in the U.S. Northeast over the past 20 years to the breakdown of the Atlantic Meridional Overturning Circulation (AMOC).
North America's 'broken heart': The billion-year-old scar from when the continent nearly ripped apart
The Midcontinent Rift is a giant tear that formed in what is now the U.S. Midwest 1.1 billion years ago. Nicknamed North America's "broken heart," it is filled with solidified magma and lava.
Scientists think a hidden source of clean energy could power Earth for 170,000 years — and they've figured out the 'recipe' to find it
Researchers have compiled a list of "ingredients" that could help resource exploration companies locate huge reservoirs of clean hydrogen, a critical element in the transition away from fossil fuels.
See the reconstructed home of 'polar dinosaurs' that thrived in the Antarctic 120 million years ago
Fossil sites in Australia hold pollen and spores from the dinosaur age, when the island straddled the Antarctic Circle. Now, scientists have re-created the habitat of "polar dinosaurs," using these plant remains.

Jellyfish Lake: Palau's saltwater pool with a toxic bottom and surface waters brimming with millions of jellyfish
Palau's Jellyfish Lake is home to millions of endemic golden jellies that live in the lake's top layer but never venture below 50 feet, where the water is saturated with poisonous gas.
Invasive Asian needle ants are surging in US Southeast — and their bite can trigger anaphylaxis
Asian needle ants found in the southeastern states of the U.S. have been spreading north and west for years, but experts now consider them to be a medically important pest and urge caution.
What's an 'omega block,' and why is it messing with US weather right now?

How related are dire wolves and gray wolves? The answer might surprise you.
Recent findings indicate that dire wolves and gray wolves are distantly related, having diverged about 5.7 million years ago and, as far as scientists can tell, never interbred since then.
Yellowstone holds potentially untapped cache of 'carbon-free' helium for rockets, reactors and superconductors
Conventional helium production comes with enormous carbon emissions, so scientists are looking for alternatives in places like Yellowstone, Tanzania's Rukwa Rift and India's Bakreswar-Tantloi province.
