The Ledecky Page -- The Saga Continues -- She Has Never Lost A Race On The Big Stage -- August 9, 2016

My wife tells me Katie Ledecky won the gold in the 200 meter freestyle.

From a reader, this link, apparently shown this morning on NBC: http://www.today.com/video/see-katie-ledecky-as-a-tot-meeting-al-roker-on-today-in-1998-740702275505.

This is truly amazing!

The Next Big Thing

Google data centers and power consumption. A lot of dots will connect. The Eric Schmidt - Hillary Clinton connection is starting to make sense.

From The [London] Independent, January 23, 2016:  Global warming: Data centres to consume three times as much energy in next decade, experts warn.

And that's just the start. Go ahead. Google it.

Genetics
For The Granddaughters

When biologists talk about genomes, they use shorthand. Chromosome nomenclature is now composed of three letters followed by a number. The number is the chromosome number of the species being considered.

The three letters are all capitalized. The first letter is the first letter of the genus; the second two letters are the first two letters of the species.

For example, human chromosome #11 is known as HSA 11 (Homo sapiens 11). For the Capuchin monkey, its chromosome #2 is CCA 2 (Cebus capucinus 2).

Others:
  • chimpanzee, PTR: Pan troglodytes
  • mouse, MMU: Mus musculus domesticus)
  • and the link provides about a dozen examples
I don't when they started using this shorthand, it certainly wasn't mentioned when I was in college many decades ago, and I only recently came across it while looking up something else.
