A short postscript on my trip to Brazil:
If it wasn't so hard to get there, Natal would probably be a nice beach resort.
In Rio, I got to eat at the restaurant where ‘Girl from Ipanema’ was supposedly written, a chic street-corner spot. We also visited the Sugar Loaf and the 2330-foot Jesus.
Sorry, no pictures from the beach.
All about the Girl from Ipanema.

Nature:
Snapshot taken of the tiniest time interval.
"A group led by Ferenc Krausz of Vienna University of Technology used pulses of laser light to watch electrons moving around atoms, and were able to distinguish events that took place 100 attoseconds -- or 10-16 seconds -- apart1.... The attosecond (10-18 s), also known as a quintillionth of a second, is the timescale of atomic events. In Niels Bohr's 1913 model of a hydrogen atom, it takes about 150 attoseconds for an electron to orbit the proton."
NYT:
Hubble closes in on Big Bang.
"Among the roughly 10,000 new galaxies revealed by a million-second-long exposure of a small patch of dark sky in the constellation Fornax are several dozen faint reddish spots that could be infant galaxies just emerging from the ‘dark ages’ that prevailed in the first half-billion years after the Big Bang, when stars had not yet had time to form, the astronomers said."
