An iridescent feathered dinosaur

Hot in science news today is a recently published paper from Nature about a newly discovered plumed dinosaur with iridescent feathers. In the past few years, we’ve had to rethink our conception of dinosaurs as giant lumbering lizards to nimble, gregarious, and feathered proto-birds.
What’s particularly exciting about this dinosaur, named Caihong (meaning ‘rainbow’), is the range of techniques brought to bear to reconstruct the colors it may have had. The scientists based these on electron microscope readings of imprints on rocks, comparing them with modern extant samples to determine their light absorbing properties.

The rich get richer, the poor get poorer

The Rate of Return on Everything, 1870-2015 asks (and answers):

What is the aggregate real rate of return in the economy? Is it higher than the growth rate of the economy and, if so, by how much? Is there a tendency for returns to fall in the long-run? Which particular assets have the highest long-run returns?

And what’s key here is that if the rate of return is greater than the growth of the economy, inequality is exacerbated. Findings: over the past 150 years, the rate of return has been double the economic growth.
