Could baby’s first bacteria take root before birth?
https://www.Nature.com/articles/d41586-018-00664-8 Interesting discussion of the controversy around detecting trace exogenous sequences in human tissues. Perhaps relevant to #exRNA?

“The tool, described in Nature on 28 March1, is not the first software to wield artificial intelligence (AI) instead of human skill and intuition. Yet chemists hail the development as a milestone, saying that it could speed up the process of drug discovery and make organic chemistry more efficient.
“What we have seen here is that this kind of artificial intelligence can capture this expert knowledge,” says Pablo Carbonell, who designs synthesis-predicting tools at the University of Manchester, UK, and was not involved in the work. He describes the effort as “a landmark paper”.”

Nels and Vincent speak with Jim Bull about the results of genetic models which suggest that the evolution of inbreeding in response to lethal gene drive might make population control difficult to achieve.
21khz: The Art of Money In Music
December 31, 2015Some quick thoughts after listening to first 9 episodes
“Will Musicians Survive in the Age of Free When the “Bottle” is worth more than the wine” – a great line & an observation that the spotify platform is worth more than its music . See also:

“Intent, Licenses and “Sweat of the Brow” – helpful discussion of copyright but it would have been nice to hear about copyleft & re-combining of artworks
“two letters and a number” – MP3.com was originally someone’s name. Robertson’s story how on how to be sued & wooed simultaneously
“so… Why does Liza Minnelli get paid when the Sex Pistols Stream?” – how to weight things (downloads or listeners) & various frauds based on this…
Can you Sell Something that Doesn’t Exist? – Superfans: would you rather collect unemployment or by the latest Doors album?

Metallurgy: Iron production electrified : Nature : Nature Publishing Group
October 20, 2013Iron production electrified. New tech for extraction of Fe directly from its oxide w/o C via high-T #electrolysis.
http://www.nature.com/nature/journal/v497/n7449/full/nature12102.html
This piece contains an interesting discussion of new blast furnace technology, which enables one to extract the oxygen directly from iron oxide without the need for carbon or the creation of carbon dioxide as it uses electrolysis. The key idea is being able to do this at very high temperatures.

Kerri Smith: Extracting iron from its naturally found form, iron oxide is a hot and heavy business. You throw your iron oxide and some carbon into a blastfurnace and then heat it to 1600 degrees Celsius, out comes iron, worldwide about a billion tons of it a year, but also outcomes carbon dioxide- bad news for the environment. Scientists would like to use other friendlier methods to make iron. This week a team from MIT reports a way to convert iron oxide to iron using electricity. It’s not a new idea. It’s basically a form of
electrolysis which extracts the oxygen leaving pure iron behind. But they’ve gotten over the biggest problem, finding material that can withstand the temperatures of molten metal oxides. Metallurgist Derek Fray at the University of Cambridge in the UK has written a News and Views article about the research. He started by telling me how much CO2, iron production is responsible for.
