Earth's extraordinary deep biosphere is our next great frontier
A fantastic alien adventure can be found on our very own planet by studying the microbial life in Earth's crust, according to Karen G. Lloyd's new book Intraterrestrials
Earth's upper mantle is revealing the deepest effect of human activity
As the Aral Sea has been drained by irrigation and dried up, the mass loss on the surface has caused Earth’s upper mantle to rise up, lifting the emptied sea bed an average of 7 millimetres per year
Supergiant crustaceans could live across half the deep-sea floor
The enigmatic crustacean Alicella gigantea is the world’s largest amphipod, but like all deep-sea creatures it hasn’t proved easy to find
How one farm is testing multiple carbon-capture tricks all at once
Rock dust, compost and biochar can all help capture carbon dioxide and boost crop yields when spread on soil – but researchers are discovering they may be even more effective when used in combination
How cloud-seeding could help us predict when it will snow
These brilliant images show how researchers in Switzerland are using weather-modification techniques to understand how ice crystals form in clouds, an important and poorly understood factor in climate and weather models
Forests' vanishing snow is also bad news for carbon storage
The loss of snow cover in temperate forests is set to slow their growth and reduce their ability to remove carbon from the atmosphere, an overlooked consequence of climate change
World's farmers won't be able to keep up with climate change
Even if agricultural practices adapt in response to higher temperatures, five of the world's six main staple crops will suffer severe losses due to climate change
Earth wouldn’t have ice caps without eroding rocks and quiet volcanoes
Throughout Earth's history, ice caps have been very rare, but a model of the past 420 million years suggests an explanation for why they sometimes form
The prospectors hunting hydrogen along a US continental rift
A gaggle of companies are searching the US Midwest for underground hydrogen fuel produced by a billion-year-old split in the continent – New Scientist visited one of the first to start drilling
