Phys.org / Decades-long study finds 'stable' soil carbon degrades

After nearly four decades, the world's longest-running soil warming experiment is revealing a surprising result: even "stable" carbon in forest soils can break down as temperatures rise, releasing more CO₂ into the atmosphere. ...

Phys.org / Ancient farming clues may finally expose where humanity's most important wheat first emerged

The exact origin of bread wheat (Triticum aestivum) is still a mystery, but researchers believe they are edging closer to the source of one of the most important food staples worldwide. Using genetic studies and ancient plant ...

Phys.org / How a free flow of information can amplify incorrect ideas

The idea that information should flow freely is deeply embedded in the design of social media. The assumption is that the more information is produced and shared, the better. However, simulations by a team of scientists including ...

Phys.org / An anomaly in global sea level rise is explained by deep ocean heating

Climate scientists like to keep their accounting books neat and balanced. As climate change alters energy flows all across the planet, which in turn causes effects like sea level rise, ice melt and more, keeping close track ...

Science X / Snowball Earth may hide a far stranger climate cycle than anyone expected

During the Sturtian glacial period during the Neoproterozoic Era, Earth underwent periods of global glaciation, which have been described as either "Snowball" and "Slushball" Earth scenarios. In Snowball Earth models, the ...
