Atmospheric carbon dioxide drawdown from rock weathering processes has its limits

A new study found that atmospheric carbon dioxide (CO2) drawdown from chemical weathering of rocks is limited to a narrow range of moderate erosion rates. This has significant implications for understanding the constraints of weathering-mediated CO2 drawdown and resolving conflicting data on its impact on the climate.

How a common food ingredient can take a wrong turn, leading to arthritis

Researchers have identified how bacteria in the digestive system break down tryptophan into an inflammatory chemical that primes the immune system towards arthritis. A Mediterranean diet rich in plant-based fibers and lean meats may tip the balance towards anti-inflammatory pathways, while a Western diet may exacerbate inflammation.
