Effect of alder on soil bacteria offers an alternative explanation to the role played by alder in rock weathering [Biological Sciences]

The article by Perakis and Pett-Ridge in PNAS (1) stimulated an interesting discussion (2) on the role of nitrogen-fixing alder in enhancing rock weathering and supply of rock-derived nutrients.

Researchers synthesize 'impossible' superconductor

Researchers from the U.S., Russia, and China have bent the rules of classical chemistry and synthesized a "forbidden" compound of cerium and hydrogen—CeH9—which exhibits superconductivity at a relatively low pressure of 1 million atmospheres. The paper came out in Nature Communications.

Why magnetism in certain materials is different in atomically thin layers and their bulk forms

Researchers led by MIT Department of Physics Professor Pablo Jarillo-Herrero last year showed that rotating layers of hexagonally structured graphene at a particular "magic angle" could change the material's electronic properties from an insulating state to a superconducting state. Now researchers in the same group and their collaborators have demonstrated that in a different ultra-thin material t

Earth could warm even faster as climate change progresses

As climate change continues, the rate at which Earth warms could increase in the future, according to new simulations. Researchers used a state-of-the-art climate model to successfully simulate—for the first time—the extreme warming of the Early Eocene Period, which scientists consider an analog for Earth’s future climate. The researchers found that the rate of warming increased dramatically as c

Getting to the root of carbon storage in deep soils

Land use changes, nutrient depletion, and drought can make plant roots grow deeper into the soil. But scientists question how that growth affects carbon in the soil. Could more roots reaching deep soil layers result in more carbon being sequestered? Or will this root-driven mineral weathering unlock older carbon in deep soils? Combining advanced imaging techniques, scientists examined the impact o
