Computationally classifying fungal lifestyles

As a proof of concept, researchers developed an algorithm that "taught" a computer how to classify 101 representative genomes of Dothideomycetes, the largest class of fungi, by lifestyles. The machine "learned" to identify ...

Plant roots increase carbon emission from permafrost soils

A key uncertainty in climate projections is the amount of carbon emitted by thawing permafrost in the Arctic. Plant roots in soil stimulate microbial decomposition, a mechanism called the priming effect. An international ...

New insight into the origin of water on the earth

Scientists have found the interstellar organic matter could produce an abundant supply of water by heating, suggesting that organic matter could be the source of terrestrial water.

Study finds warming peat may boost greenhouse gases

Warming temperatures in cold-climate peatlands may over time trigger decomposition of old, deeply buried peat and increase emissions of climate-harming methane and carbon dioxide into the air, according to a study led by ...

Pinpointing the origins of Jerusalem's Temple Mount

Integrating radiocarbon dating and microarchaeology techniques has enabled more precise dating of the ancient Wilson's Arch monument at Jerusalem's Temple Mount, according to a study published June 3, 2020 in the open-access ...

Exploring the neurological impact of air pollution

Air pollution has become a fact of modern life, with a majority of the global population facing chronic exposure. Although the impact of inhaling polluted air on the lungs is well known, scientists are just now beginning ...
