And the Squirrels were Merry

Posted on Categories Discover Magazine

By: Russ Campbell I grew up in Fishtown, Philadelphia, an inner city grid of red-brick row homes, corner bars, candy shops, and barely-breathing factories. Fishtown was not known for its wildlife. There were birds. A wide variety, if two counts as a wide variety: big birds (pigeons) and small birds (sparrows). There were cats and an occasional dog that escaped out of someone’s yard. On rare occasions, I’d see a squirrel scampering about on the telephone pole in my backyard. This was ...read more

Since the 17th century, it has been recognized that sl ...read more

The authors, Qiaozhen Chen et al. from Zhejiang in China, used fMRI to record brain activity while 15 volunteers listened to two musical pieces: Psy’s ‘Gangnam Style‘ and a “light music” control, Richard Clayderman’s piano piece ‘A Comme Amour‘.

A wimpy La Niña is on the way toward La Nada status

Posted on Categories Discover Magazine

La Niña typically cools the Pacific. But this time, large swathes of warmer-than-average sea temperatures have muted the cooling. A comparison of sea surface temperature anomalies in the Pacific Ocean for two seven-day periods: Dec. 28, 1998 to Jan. 3, 1999; and Dec. 26, 2016 to Jan. 1, 2017. The strong La Niña of 1998/1999 is characterized by widespread blue colors concentrated especially along the equator west of South America. Whereas today’s Pacific i ...read more
