The snow forest of North America may be about to shrink
One of nature’s woody behemoths — the North American snow forest — may soon begin shrinking. The continent’s boreal forest reposes in subarctic latitudes, spanning much of Alaska and Canada. Scientists had…
Nobel Laureate John B. Goodenough dies at 100
Goodenough’s visionary efforts in developing lithium ion batteries played an instrumental role in revolutionizing the way we generate, store, and use energy. Renowned scientist and Nobel Laureate, John B. Goodenough, passed away…
Irrigation may be shifting Earth’s rotational axis
Runoff from irrigation has moved so much water from land to sea that Earth’s rotation might have measurably shifted. Computer simulations suggest that from 1993 through 2010, irrigation alone nudged the North…
Portable 3D-printed sensor detects low concentrations of water pollutants
3D-printed sensor detects low concentrations of pesticides, offering a cost-effective and portable solution for water monitoring. Monitoring water pollution is of the utmost importance to maintaining ecosystems, safeguarding human health, and ensuring…
The Amazon might not have a ‘tipping point.’ But it’s still in trouble
The shore of a sea of nearly 400 billion trees winds through the central Brazilian state of Mato Grosso. Here, the Amazon rainforest rubs up against the Cerrado, the world’s largest savanna….
Why is the North Atlantic breaking heat records?
In the past few weeks, sea-surface temperatures in some parts of the North Atlantic Ocean have soared to record heights. The anomalous warming is occurring in a large swath stretching almost one-third…
Rising groundwater threatens to spread toxic pollution on U.S. coastlines
Hidden flows of water are poised to flush toxic contamination into U.S. coastal communities. Sea level rise from climate change won’t just force shorelines to retreat — in inland areas, it will…
Wildfire smoke is blanketing the U.S. East Coast. It won’t be the last time
Even as the thick clouds of smoke from wildfires raging in eastern Canada, which blanketed the U.S. East Coast in a dangerous orange haze, begin to dissipate, researchers are warning it’s a…
Surviving a drought may help forests weather future dry spells
Some forests take one-two punches surprisingly well. Researchers have shown that certain California forests exposed to two successive droughts weathered the second one much better than forests only hit by the later…
