Astute piece in the Chronicle Review about the opportunism of disputing the truth that actually grew out of the academy:

It’s not just garden-variety ignorance that periodically appears in public-opinion polls that makes us cringe or laugh. A 2009 survey by the California Academy of Sciences found that only 53 percent of American adults knew how long it takes for Earth to revolve around the sun. Only 59 percent knew that the earliest humans did not live at the same time as the dinosaurs.

As egregious as that sort of thing is, it is not the kind of ignorance that should most...

The amount of dissolved carbon in the world's oceans is roughly equivalent, and likely greater, than atmospheric concentrations of CO2. Some of it gets semi-permanently sequestered, some gets released up into the atmospheric in a process that has been in place for millions of years. But with the global carbon picture changing, understanding the details of these processes has become more urgent: the slightest changes in ocean temperature or acidification (not hypothetical: we know these conditions are in flux) could usher in major changes in the relationship between the carbon in...

Long long ago in a land far far away not so far from here at all, crocodiles, dinosaurs, and birds all arose from early reptiles called thecodonts.

 

Using new computational methods developed by assistant professor of statistics Liang Liu, Travis Glenn of the College of Public health and others, an international team of scientists has shed more light on an obscure period of avian evolution and further untangle the bird family tree.

Members of the Avian Phylogenomics Consortium—composed of 200 researchers from 80 institutions and 20 countries—have sequenced and...
