This Week on CENtral Science: #SheriSangji, China’s Solar Industry, and more

I’m out of town today, folks, so I scheduled a roundup for everything we had as of overlord press time.
Tweet of the Week:

And now, to the network:

Cleantech Chemistry: No Magic In China’s Solar Industry

Newscripts: In Print: Droplets of Rain, Strands of Honey and Amusing News Aliquots

The Safety Zone: On the importance of teaching safety and Patrick Harran arraigned on four felony counts, #SheriSangji case to be continued in June

The Watch Glass: Brain Chemistry and U.S. Prepares to Launch Sea-Air Study and Art Directors Club Selection, 1965 and Science, world politics, and human rights

Talking about science online at #sciodc

This Wednesday, May 1, ScienceOnlineDC will be holding its inaugural event.

ScienceOnlineDC is one of several local satellites of ScienceOnline, a nonprofit organization that facilitates conversations, community, and collaborations at the intersection of science and the Web. Our goal is to bring together science journalists, bloggers, federal and private research scientists, policymakers, and other science enthusiasts in the DC metro area for dynamic discussions about how science is carried out and communicated online. My co-organizers are Geoffrey Hunt of the American Society for Biochemistry & Molecular Biology, AAAS Science & Technology Policy Fellow Jamie Vernon, and Hannah Waters of the Smithsonian Institution.

Our first event will focus on federal agencies’ social media policies – how does government transparency influence the social media activities of scientists and communications staff? Here’s the panelist lineup:

Jamie Vernon, moderator

Gretchen Goldman, analyst, Union of Concerned Scientists (check out her post about Wednesday’s event)

Megan McVey, communications coordinator, United States Global Change Research Program

Sarah Dewitt, communications officer, NASA, Office of the Chief Scientist

John Ohab, public affairs specialist, Naval Research Laboratory

One of the hallmarks of ScienceOnline events is the unconference format. Sure, we’ve rounded up some experts to put in the front of the room, but most of the conversation will be driven by the attendees, both in person and online. Even if you can’t be there in person, chime in via the livestream and twitter (#sciodc). Should be a great discussion.

Of course, you may be wondering why I’m pitching this event to an audience of chemists, most of whom are not in the DC area. I’ll tell you why. Because it’s important for chemists to be involved in these conversations. Because many of you are already having such conversations on twitter and each other’s blogs. And some of those conversations include pondering who could be the chemist version of Neil deGrasse Tyson. But chemistry doesn’t need one deGrasse Tyson; it needs several. So, let’s move those discussions out of the chemistry inner circle and into Science, writ large. Chemistry is the central science, after all.

And you can start by attending any gathering with other people in your community who are interested in how science is communicated. As I said earlier, ScienceOnlineDC is only one of several satellites. Others with regular events include Seattle, Vancouver, and the Bay Area. There are SpotOn events in London and New York. Attend a local #SciTweetUp or Science Cafe. Or participate in the livestreams and twitter conversations that often accompany these events.

And if you are in DC on Wednesday, c’mon by. We’d love to have you.

UPDATE, 5/6: Doh! How could I leave out ScienceOnlineBeantown???

My apologies for a few weeks hiatus over here at Artful Science.

Last summer I got married and we are finally off on our honeymoon to Uzbekistan (aka the honeystan) where we will explore some awesome Silk Road architecture.

Given that we’ll be looking at a lot of mosaics, I thought I’d point you to this post on the conservation of tile art and the 2011 Nobel Prize in chemistry.

See you at the end of April…

Gold gilding, ancient amber and a mysterious hidden sculpture: A new cultural heritage journal launches!

This gold gilding at the Reales Alcazares of Sevilla was added in the 19th century.

This gold gilding at the Reales Alcazares of Sevilla was added in the 19th century.

There’s beautiful gold gilding at Reales Alcazares royal palace in Seville, Spain.

Yet it turns out that the pretty gold gilding you see in the image on the left is not precisely original.

The World Heritage Site was originally built in 914 AD, and then expanded from the 14th to the 16th century.

Recently, Spanish researchers found a layer of paint lying below the gold gilding that contains lead chromate, a pigment that wasn’t used until the 19th century. So the gold lying above must have been added afterwards.

Yellow lead chromate pigment is responsible for the bright color of many old school buses, and it was even used as a colorant for yellow candy before falling out of favor because both lead and chromate are extremely toxic.

Spanish researchers report that the lead chromate layer was added sometime after 1818 above a deteriorated layer gold gilding, probably as part of a 19th century restoration project.

The lead chromate may have been painted on as false gold to keep up appearances before new gold gilding could be applied.

Or it’s possible that the lead chromate was painted on just before the new gold gilding: The paint may have acted as a foundation layer to help the new gold gilding adhere.

This conundrum is reported in the inaugural issue of Heritage Science, the first peer-reviewed journal to focus entirely on cultural heritage science. (Welcome!!)

This 7th century BC amber found in an Italian tomb originally came from the Baltic area even though Italy had its own sources of amber.

This 7th century BC amber found in an Italian tomb originally came from the Baltic area even though Italy had its own sources of amber.

There’s a variety of interesting topics reported in the journal’s first edition, including a way to determine the geographical origin of amber which provides clues about early trading roots of the fossilized tree resin.

There’s also an analysis of medieval Hungarian silver coins, and several papers on the effects of pollution and humidity on cultural heritage objects, from ancient architecture to antique books.

The issue also contains a cool paper about a sculpture accidentally discovered behind a wall of St Petersburg’s Winter Palace in 2010.

The sculpture, called Fugitive Slave and made by the Russian artist Vladimir Beklemishev, was inspired by the anti-slavery novel Uncle Tom’s Cabin. It was initially exhibited at the World’s Fair in Chicago in 1893, and then sent to Russia before being hidden in the palace wall after the sculpture suffered heavy damage during World War Two.

The sculpture was made to look like bronze, even though it is definitely not bronze.

That’s why the scientists are keen to study its make-up: The pseudo bronze involves creative use of gypsum, iron, copper and arsenic.

But perhaps the most interesting read in the inaugural issue of Heritage Science is the very pointed essay by journal editor Richard Brereton.

Brereton does not mince words about the devastating effect of 20th century progress on cultural heritage. He begins with his hometown of Bristol, where “post-war planners destroyed more of Bristol than [World War 2] bombs” and goes on to decry lost heritage in other parts of Europe, Asia and the Americas.

“Capitalists, aristocrats, democrats and communists were all at it in the twentieth century, destroying a heritage that had evolved very slowly for centuries. In the past there had been waves of localized destruction, for example in Rome, the Popes raided marble from the Coliseum in order to construct new churches, and in Latin America, the Spanish conquistadors organised a mass destruction of Inca, Aztec and many other cultural artefacts – for example there are only fragments of Aztec written texts available due to the enthusiastic destruction of material by priests. But the twentieth century appears unique for a mass international desecration of our global historic heritage. Most governments were dependent on some sort of political support, even tyrants have to feed their armies, and people wanted hot water in the homes and good food on the table and washing machines and televisions rather than fine paintings and important buildings.”

Here’s to reading more in Heritage Science about how 21st century science can inform efforts to conserve what’s not been destroyed in the 20th century.
