Opinion
A (chemical) potential theory of life's origin
Philip Ball says we should look beyond the molecules that make us to find the spark of life

FeatureA chemical account of evolution
Bob Williams and Ros Rickaby examine the co-evolving chemistry of the environment and life

Feature
Life, but not as we know it
Biology has been pretty successful at creating life, but now chemistry wants a crack at it
-
Research
Seeds of life incubated in proto-planetary nurseries
Organic molecules that were the potential precursors of life on Earth could have been synthesised in a part of the cosmic environment hitherto considered to be chemically inert
