Harvard study models forelimbs of echidnas to shed light on evolution – Harvard Gazette

Using a detailed, musculoskeletal model of an echidna forelimb, Harvard scientists are not only shedding light on how the little-studied echidna’s forelimbs work, but also opening a window into understanding how extinct mammals might have used those limbs.

Greenhouse gas ‘detergent’ recycles itself in atmosphere — ScienceDaily

A simple molecule in the atmosphere that acts as a ‘detergent’ to breakdown methane and other greenhouse gases has been found to recycle itself to maintain a steady global presence in the face of rising emissions, according to new research. Understanding its role in the atmosphere is critical for determining the lifetime of methane, a powerful contributor to climate change.
