Signing on and reading up

OK, so I have finally taken some steps toward keeping up on the literature and staying aware of this crazy industry called Academia.  I've subscribed to paper versions of the Chronicle of Higher Education and Science, and signed up for emails from ArXiv about quantitative biology and e-alerts from Nature Publishing.  I regularly peruse the Science sections of the BBC and NYTimes.

What else do people do to stay up to date on general science developments?  I'm open to more suggestions, though I'm not quite sure I can stomach an RSS feed.  I'm looking more for a sprinkler system of relevant, edited science news rather than a fire hose.

Short Course on Complexity

The Santa Fe Institute (SFI) is an institution and think tank focusing on complex systems and transdisciplinary research.  SFI is hosting a short course in Austin, Texas that should be excellent.  The program coordinator is Dr. Melanie Mitchell, author of "Complexity: A Guided Tour" (which is an excellent introduction to complex systems).  My advisor, Dr. Aaron Clauset, will be speaking, along with Drs. Chris Moore, Luis Bettencourt, Simon DeDeo, Jennifer Dunne, Paul Hines, Bernardo Huberman, and Lauren Ancel Meyers.  More info here:

Alessandra Volta and the invention of the battery

I have spent the past two weeks in Como, Italy for a wonderful conference called Quantitative Laws of Genome Evolution.  I will write more about it later, but let me at least thank Marco Lagomarsino for organizing such a wonderful conference.
The location was ok, too.  Como is a beautiful place; I was in the region 15 years ago and was eager to return in the name of science.  However, during my first visit to Lombardy, I wasn't aware of the rich scientific history in the region.  Como was the home of Alessandro Volta, who discovered the first battery by creating a continuous current between two metals and stacking these in a voltaic pile.

Today I visited the Tempio Voltiano to try to glean some details of Volta's life from the Italian descriptions and to look at his instruments and early batteries. I was attracted to the exhibit after learning that Volta discovered the battery in 1800.  I found out that Volta was an interdisciplinary scientist, tinkering and building eudiometers, investigating "inflammable gases" (e.g., methane), studying atmospheric conditions, building capacitors, etc., all from materials such as wax, clay, wood, stone, metal, paper, and glass.  It seems miraculous to me to design something as complex as a battery from these supplies without any post hoc knowledge.

There were also displays about the study of "animal electricity," the view supported by Volta's rival Luigi Galvani, including many mummified frog legs and one manta ray preserved in formaldehyde.  What an interesting time to be studying the movement of electrons!  Did energy come from the dead animal itself?  Or was the animal just a vehicle?  Volta was inspired to build his voltaic piles to prove his rival wrong, ultimately inventing an incredibly useful technology.  He received recognition in his time, as well, demonstrating his early batteries to Napoleon in Paris.

And now I leave you with a few pictures from the museum. Enjoy!
