Human civilization likely alone

The good news: it's all ours. The bad news: there's nothing to stop us. A new model of civilization, arrived by taking the Drake equation and plugging in models of chemical and genetic transitions on paths to the origin of life, predicts that humanity is the only advanced one in observable space.

As Dr. Sanberg told Universe Today via email:

“One can answer [the Fermi Paradox] by saying intelligence is very rare, but then it needs to be tremendously rare. Another possibility is that intelligence doesn’t last very long, but it is enough that one civilization survives for it to become visible. Attempts at explaining it by having all intelligences acting in the same way (staying quiet, avoiding contact with us, transcending) fail since they require every individual belonging to every society in every civilization to behave in the same way, the strongest sociological claim ever. Claiming long-range settlement or communication are impossible requires assuming a surprisingly low technology ceiling. Whatever the answer is, it more or less has to be strange.”

Financial consultancy says that Bitcoin's value is speculative, and as a currency, it should be worth $810

Wall Street consultants Quinlan & Associates have published "Fool's Gold: Unearthing The World of Cryptocurrency," a $5000, 156-page report that predicts that Bitcoin will drop to $1800 by next December, and down to $810 by 2020 (it is currently trading in the $14,000 range). Read the rest

China's capital controls are working, and that's bursting the global real-estate bubble

More news on the Chinese crackdown on money-laundering and its impact on the global property bubble: the controls the Chinese government has put on "capital outflows" (taking money out of China) are actually working, and there's been a mass exodus of Chinese property buyers from the market, with many abandoning six-figure down payments because they can't smuggle enough money out of the country to make the installment payments.

July: Vancouver imposes a 15% tax on foreign real estate speculators; September: home sales drop by a third

Vancouver has been wracked by a white-hot property bubble driven primarily by offshore speculators, mostly Chinese, who have driven up the price of housing beyond the means of working Vancouverites, crippling the city's daily life as workers, students and families struggle to find somewhere -- anywhere -- to live.

Chinese real estate bubble is "biggest in history"

Wang Jianlin made billions speculating on Chinese real-estate; now that he's diversified into buying Hollywood movie studios and chains of movie theaters, the richest man in China is prepared to say what many have known: the Chinese property market is a huge, deadly bubble that's ripe to burst.

Singaporean bank stops lending money to UK property speculators

Singaporeans are the most prolific speculators on UK commercial property, and the United Overseas Bank is the most prolific lender to Singaporeans who want to speculate in that market -- and now they're turning off the faucet. Read the rest

Tube-map labelled with one-bedroom flat rental rates

Since the crisis, the number of people renting in the UK has sharply increased, but the number of landlords has decreased, as a smaller and smaller number of richer and richer people control the destiny of more and more Britons. Read the rest

New York Times helps promote book poorly reviewed by New York Times

In the past year, The New York Times Sunday opinion page has run three different columns by Moises Velasquez-Manoff, a writer whose new book argues that the hygiene hypothesis — the idea that over-cleanliness can make you sick — is the one true cause behind everything from autism, to celiac disease, to allergies. While the hygiene hypothesis, itself, is perfectly plausible, Velasquez-Manoff's extension of it to cover a host of hot-button disorders and cures for said disorders is much less plausible ... something that was pointed out in a negative review of his book that ran in, yes, The New York Times. Matthew Herper explores this strange dichotomy at Forbes. Read the rest

How would you short London?

Here's a finance riddle: how would you short London's property bubble? House prices are up GBP50K in the last six months, our freeholder is making noises about either buying or forcing us out in order to build a giant tower, and they sold off Scotland Yard (!). They say the market can stay irrational longer than you can stay solvent, and I've been marvelling at the irrationality of London's property market since I moved there in 2003. Just for the sake of argument, if you wanted to put a bet down on a property value crash, how would you make it? Read the rest

Bubblenomics: how the Beanie Babies speculators got it wrong

Buzzfeed's Hunter Schwarz revisits 1998's "Scholastic Beanie Baby Handbook," which predicted values of Beanie Babies in 2008, and compares them to the current-day eBay clearing price for these same speculative items. For example, the Stripes the Dark Tiger doll, which retailed for $5 and traded for $250 in 1998 was predicted to rise to $1,000. Today it can be had on eBay for $9.95. And the $4,000-$5,000 estimated 2008 value for the Violet Teddy was also way off, though Violet is today a $700 item ($700 was also what it traded for in 1998).

Three important takeaways from the "ladies like big penises" study

First: When shown images like the one above and asked to choose which men they found more attractive, women cared significantly more about body shape than penis size. (Also, it's worth noting that the image above is meant to show you an average, actual human guy in the middle and the extremes of body shape and penis size that were shown to the women on either side of him. In reality, the women were shown a full spectrum of images mixing different body types and penis sizes).

Second: The hypothesis (that human women sexually selected human males to have the larger-than-other-primates junk they are blessed with today) comes with some big questions, including the obvious — flaccid penis size does not correlate well to erect penis size.

Third: As Faye Flam points out at The Knight Science Journalism Tracker, the journal Proceedings of the National Academy of Sciences might need a new acronym (or, at least, different subject matter).

NASA downplays still-unannounced findings from Mars

Just before Thanksgiving, the lead mission scientist for the Curiosity rover told NPR that his team had found something that would "be one for the history books." Naturally, we all began speculating about the presence of life, giant obelisks, and half-buried Statues of Liberty. Yesterday, however, a different NASA spokesman basically asked the world to not get its hopes up too high, revising the level of importance down from "earthshaking" to "interesting". So far, nobody has said what, exactly, was discovered. (Via Colin Schultz) Read the rest

The kids dig minor keys: How pop music has changed since 1960

While 85% of Billboard Top 100 songs of the 1960s were written in a major key, that preference no longer holds true today. Minor key songs have become the majority, representing about 60% of modern hits. Scientific American's Helen Lee Lin delves into this, and other documented changes in musical preference. The research is totally interesting, even if the scientists don't seem to have a good idea of what it means. Maybe we're depressed. Or maybe we're just trying to sound more mature. Here's the original paper. (Via ScienceGoddess) Read the rest

Fossils in storage: How do you sort through the backlog?

Yesterday, I posted about Pegomastax africanus, a parrot-like dinosaur whose fossil was discovered not in a remote waste in some far corner of the world, but in a rock that had sat in storage at Harvard University for 50 years.

In the post, I tried to explain why something like that could happen. The simple fact of the matter: A successful archaeological or paleontological dig will produce far more material than the original scientists have time (or money) to sort through, process, and examine. So lots of stuff ends up sitting in storage.

That led BoingBoing reader Matt Fedorko to some interesting speculation:

"...This seems like a perfect opportunity to exploit 3D scanning technology to put the shapes of fossils, at least, into some kind of digital storage area where other researchers could look at a dig's haul and start to work with them spatially, or beside any of the other data that is collected in the field or logged during the cataloging procedure."

Now, Charles Q. Choi, a journalist who wrote about the discovery of Pegomastax africanus, says that Matt's idea isn't all that far-fetched. In fact, scientists already do something like this with the fossils that do get closely examined. Read the rest

Beware of neuro-speculation

Between the downfall of Jonah Lehrer, and Naomi Wolfe's new book that claims chemicals in women's brains force us to demand our lovers shower us with roses and candy and refer to us as "goddess"*, there's been some growing backlash against the long-popular idea of better living through neuroscience. You know what I'm talking about here: You (yes, you!) can succeed at work, be more creative, improve your relationships, and have a better sex life — all you have to do is read this one interpretation of the latest in neuroscience research!

Perhaps unsurprisingly, that pitch oversells the reality. What we know about how the brain works isn't really that clear cut. But more than that, the idea of scientific self-help quite often has to severely distort science in order to make any sense. The public comes away with a massive misunderstanding of what MRI does and doesn't tell us, what hormones like dopamine actually do, and what the lab tells us about real life.

There are two big essays that you need to read before you pick up another story or book that tries to make connections between cutting-edge brain science and real life. The first, in New Statesman, is by Steven Poole and the broad overview of why it's such a problem when neuroscience becomes neuro-speculation. The second, by Maia Szalavitz at Time Magazine's Healthland blog, focuses on Naomi Wolfe's new book and uses that as a springboard to talk about the bigger issue of brain chemicals, what they are, and what they aren't.

Great moments in pedantry: Winter is coming. But why?

A work of fiction doesn't have to be scientifically accurate. It just has to make sense. All it has to do is maintain an internal logic and consistency strong enough that you, the reader, aren't inadvertently thrown out of the world. If you're frequently frustrated by detail accuracy in fiction, that's likely your problem, not fiction's. Chill out. Breath deep. Smell the flowers. Experience some imagination and wonder.

I fully endorse all the sentiments outlined above. And yet. And yet. There are some fictional details that drive me crazy. Like the seasonal shifts in George R. R. Martin's A Song of Ice and Fire series, where winter and summer last for years—sometimes decades—and nobody knows exactly when the seasons will change. It's not that I feel a burning need to prove to Martin that this can't work. Instead, it makes me ravenously curious. I keep wondering whether, given what we know about astronomy, there's any way that this could actually work somewhere, in a galaxy far, far away.

A couple of weeks ago, io9's George Dvorsky put together a little round-up of five possible scientific explanations that would make Westeros' magical reality make more sense. I chatted about Dvorsky's list with Attila Kovacs, an actual astronomer who has a postdoc position at the California Institute of Technology. They've got differing perspectives on how unpredictable and ridiculously long seasons might work. Thanks to both these sources, I feel like I better understand our universe, and can read Martin more comfortably. Read the rest
