Machine learning reveals recipe for building artificial proteins

Proteins are essential to the life of cells, carrying out complex tasks and catalyzing chemical reactions. Scientists and engineers have long sought to harness this power by designing artificial proteins that can perform ...

A small step for lungfish, a big step for the evolution of walking

(Phys.org) —The eel-like body and scrawny "limbs" of the African lungfish would appear to make it an unlikely innovator for locomotion. But its improbable walking behavior, newly described by University of Chicago scientists, ...

Antarctic sea ice is key to triggering ice ages, study finds

We've known for years that Earth's climate is like a giant Rube Goldberg machine: Pull one lever, and a massive chain of events starts into motion. Yet many of the steps that drive these changes have remained shrouded in ...
