cryonics offers almost eternal life. To its critics, cryonics is pseudoscience; the idea that we could freeze someone today in such a way that future technology might be able to re-animate them is nothing more than wishful thinking on the desire to avoid death. Many who battle nonsense dressed as science have spoken out against it: see for example Nano Nonsense and Cryonics, a 2001 article by celebrated skeptic Michael Shermer; or check the Skeptic’s Dictionary or Quackwatch entries on the subject, or for more detail read the essay Cryonics–A futile desire for everlasting life by “Invisible Flan”.

And of course the pro-cryonics people have written reams and reams of material such as Ben Best’s Scientific Justification of Cryonics Practice on why they think this is exactly as plausible as I might think, and going into tremendous technical detail setting out arguments for its plausibility and addressing particular difficulties. It’s almost enough to make you want to sign up on the spot. Except, of course, that plenty of totally unscientific ideas are backed by reams of scientific-sounding documents good enough to fool non-experts like me. Backed by the deep pockets of the oil industry, global warming denialism has produced thousands of convincing-sounding arguments against the scientific consensus on CO2 and AGW. T

Nano Nonsense and Cryonics goes for the nitty-gritty right away in the opening paragraph:To see the flaw in this system, thaw out a can of frozen strawberries. During freezing, the water within each cell expands, crystallizes, and ruptures the cell membranes. When defrosted, all the intracellular goo oozes out, turning your strawberries into runny mush. This is your brain on cryonics.This sounds convincing, but doesn’t address what cryonicists actually claim. Ben Best, President and CEO of the Cryonics Institute, replies in the comments:Strawberries (and mammalian tissues) are not turned to mush by freezing because water expands and crystallizes inside the cells. Water crystallizes in the extracellular space because more nucleators are found extracellularly. As water crystallizes in the extracellular space, the extracellular salt concentration increases causing cells to lose water osmotically and shrink. Ultimately the cell membranes are broken by crushing from extracellular ice and/or high extracellular salt concentration. […] Cryonics organizations use vitrification perfusion before cooling to cryogenic temperatures. With good brain perfusion, vitrification can reduce ice formation to negligible amounts.

Say the word “inventor” and most people think of a solitary genius toiling in a basement. But two ambitious new books on the history of innovation—by Steven Johnson and Kevin Kelly, both longtime wired contributors—argue that great discoveries typically spring not from individual minds but from the hive mind. In Where Good Ideas Come From: The Natural History of Innovation, Johnson draws on seven centuries of scientific and technological progress, from Gutenberg to GPS, to show what sorts of environments nurture ingenuity. He finds that great creative milieus, whether MIT or Los Alamos, New York City or the World Wide Web, are like coral reefs—teeming, diverse colonies of creators who interact with and influence one another.

Seven centuries are an eyeblink in the scope of Kelly’s book, What Technology Wants, which looks back over some 50,000 years of history and peers nearly that far into the future. His argument is similarly sweeping: Technology, Kelly believes, can be seen as a sort of autonomous life-form, with intrinsic goals toward which it gropes over the course of its long development. Those goals, he says, are much like the tendencies of biological life, which over time diversifies, specializes, and (eventually) becomes more sentient.

We share a fascination with the long history of simultaneous invention: cases where several people come up with the same idea at almost exactly the same time. Calculus, the electrical battery, the telephone, the steam engine, the radio—all these groundbreaking innovations were hit upon by multiple inventors working in parallel with no knowledge of one another.

The Swiss economists Bruno Frey and Alois Stutzer argue that people do not appreciate the real cost of a long commute. And especially when that commute is unpredictable, it takes a toll on our daily well-being.

imagine if we shared our commuting information so that we could calculate the average commute from various locations around a city. When the growing family of four pulls up to a house for sale for in New Jersey, the listing would indicate not only the price and the number of bathrooms but also the rush-hour commute time to Midtown Manhattan. That would be valuable information to have, since buyers could realistically factor the tradeoffs of remaining in a smaller space closer to work against moving to a larger space and taking on a longer commute.

In a cover story for the New York Times Magazine, the writer Gary Wolf documented the followers of “The Data-Driven Life,” programmers, students, and self-described geeks who track various aspects of their lives. Seth Roberts does a daily math exercise to measure small changes in his mental acuity. Kiel Gilleade is a "Body Blogger" who shares his heart rate via Twitter. On the more extreme end, Mark Carranza has a searchable database of every idea he's had since 1984. They're not alone. This community continues to thrive, and its efforts are chronicled at a blog called the Quantified Self, co-founded by Wolf and Kevin Kelly.

I have a paper in this week’s issue of Science on the cloud feedback

clouds are important regulators of the amount of energy in and out of the climate system. Clouds both reflect sunlight back to space and trap infrared radiation and keep it from escaping to space. Changes in clouds can therefore have profound impacts on our climate.

A positive cloud feedback loop posits a scenario whereby an initial warming of the planet, caused, for example, by increases in greenhouse gases, causes clouds to trap more energy and lead to further warming. Such a process amplifies the direct heating by greenhouse gases. Models have been long predicted this, but testing the models has proved difficult.

The problem of replicability in science from xkcdby Massimo Pigliucci

In recent months much has been written about the apparent fact that a surprising, indeed disturbing, number of scientific findings cannot be replicated, or when replicated the effect size turns out to be much smaller than previously thought.

Arguably, the recent streak of articles on this topic began with one penned by David Freedman in The Atlantic, and provocatively entitled “Lies, Damned Lies, and Medical Science.” In it, the major character was John Ioannidis, the author of some influential meta-studies about the low degree of replicability and high number of technical flaws in a significant portion of published papers in the biomedical literature.

have you noticed how the capacity of the media to explain in lay terms such matters as quantum physics, or cosmology, is contracting faster than the universe is expanding? The more mind warping the discoveries the less opportunity there is to fit them into 30 seconds in a news cast, or 300 words in print.

There has been a long running conspiracy of convenience between science reporters and the science being reported to leave out inconvenient time and space consuming explanations, and go for the punch line that best suits the use of the media to lobby for more project funding.

Almost every space story I have written over 50 years has been about projects claiming to ‘discover the origins of the solar system/life on earth/life on Mars/discover the origins of the universe, or recover parts of things like comets because they are as old as the sun, except that we have discovered they aren’t ancient at all.’ None of them were ever designed to achieved those goals. They were brilliant projects, brilliantly misrepresented by the scientists and the reporters because an accurate story would have been incomprehensible to 99.9% of readers or viewers.

rather than being forced to wait for parliament to meet to air their dissent, now opposition parties are able to post pre-emptively their criticisms online, shifting the time and space of Singapore's political debate

Singapore's People's Action Party (PAP)-dominated politics are increasingly being contested online and over social media like blogs, Facebook and Twitter. Pushed by the perceived pro-PAP bias of the mainstream media, Singapore's opposition parties are using various new media to communicate with voters and express dissenting views. Alternative news websites, including The Online Citizen and Temasek Review, have won strong followings by presenting more opposition views in their news mix.

Despite its democratic veneer, Singapore rates poorly in global press freedom rankings due to a deeply entrenched culture of self-censorship and a pro-state bias in the mainstream media. Reporters Without Borders, a France-based press freedom advocacy group, recently ranked Singapore 136th in its global press freedom rankings, scoring below repressive countries like Iraq and Zimbabwe. The country's main media publishing house, Singapore Press Holdings, is owned by the state and its board of directors is made up largely of PAP members or other government-linked executives. Senior newspaper editors, including at the Straits Times, must be vetted and approved by the PAP-led government.

[T]he original cost [estimate] was 1.5 billion with completion targeted in 1965. The "actual" historical events went something like this. The NASA cost estimating gurus in 1961 projected an amount close to $7 Billion to do the entire program.33 34 This figure was apparently padded to $10-$12 Billion by management prior to giving that estimate to James Webb, the NASA Administrator. Mr. Webb (within hours of receiving the $10-$12 Billion figure) placed an "administrator's discount" on NASA’s ability to predict costs with due precision and by the stroke of his own pen, changed the estimate to $20 billion and submitted it to Vice President Linden B. Johnson. In the words of Robert Seamans Jr., (the Associate Administrator at the time) "We were aghast!"35 This cavalier beginning describes how Apollo's original fiscal requirements arrived at the steps of the Capitol and was subsequently blessed by Congress. Ironically, the $20 billion amount submitted by Mr. Webb to the Vice president appeared to be a completely arbitrary and highly irregular move. In anyone's book it was a radical cost estimating maneuver to be sure. But in the end, Mr. Webb's innate business sense and the courage to follow what that sense told him validated his action. It turned out to be a leadership demonstration of profound foresight. In the end the "real cost" of Apollo ultimately surpassed Mr. Webb's $20 billion estimate with a price tag of $25.4 billion as was reported to congress in 1973. The final program cost varies depending on what we include or exclude in the calculations,36 37 38 but in all instances exceeds $20 billion.

Review sites depend on user trust, and that trust is eroded when businesses are able to manipulate their own reviews. Some, including Yelp, view themselves as passive conduits for their users' reviews. Others take a more active role in fighting against censorship of patients. We think the latter approach makes more sense.

"it's scary to be involved in litigation," Levy said. "For many ordinary people, the easiest thing is to move on with your life."

Review sites can protect the integrity of their review processes by actively fighting such takedown requests.

What many of these sceptics – or deniers, if you must – do question is a) whether – and if so by how much – this warming is anthropogenic (ie human-caused) b) whether the warming constitutes a threat – or whether its benefits might in fact far outweigh its drawbacks c) whether this warming likely to continue or whether – as happened without human influence at the end of the Roman warm period and the Medieval warm period – it will be followed by a period of natural cooling d) whether the drastic policy measures (tax, regulation, “decarbonisation”, the drive for renewables) being enacted to ‘combat climate change’ will not end up doing far more harm than good.

Though Dr Jones’s report argues that the BBC should from henceforward give less space to sceptics, it’s difficult to imagine quite how it could possibly do so. About the only occasion on which they have been given any air space has been on hatchet-jobs like the BBC’s feature-length assault on Lord Monckton, “Meet The Climate Sceptics”.

One of the scientists was Richard Muller from University of California, Berkeley. Muller has been working on an independent project to better estimate the planet's surface temperatures over time. Because he is willing to say publicly that he has some doubts about the accuracy of the temperature stations that most climate models are based on, he has been embraced by the science denying crowd.

A Koch brothers charity, for example, has donated nearly 25 percent of the financial support provided to Muller's project.

Skeptics of climate science have been licking their lips waiting for his latest research, which they hoped would undermine the data behind basic theories of anthropogenic climate change. At the hearing today, however, Muller threw them for a loop with this graph:

The Observer piece then continues by labeling New York City Skeptics as a cult. Now a cult is often defined as “a relatively small group of people having religious beliefs or practices regarded by others as strange or sinister.” Hmm, let’s see. Well, NYCS is indeed a small group, and it probably isn’t impossible to find someone somewhere who considers our activities “strange” (though “sinister” would be pushing it). At least as strange as New Yorkers might find a group of people getting together for dinner and talking about things they are interested in — that is, not at all. But “having religious beliefs”? By what sort of distorted conception of religious belief does what Mr. Liu observed that night qualify as such? We are not told, though inquiring minds (apparently not those of Liu’s editors) wish to know.

For Liu “Skepticism starts with the feeling of being under siege by the nonthinking. It becomes Skepticism with the faith that there must be people out there who think like you do — that is, who think.” Well, that’s actually close to the mark, except that we like to think that we go by evidence not faith. But just as my spirits (metaphorically speaking) were beginning to lift a bit, I learned from Mr. Liu that skepticism has recently turned “[in]to something like a distinct, aggressive and almost messianic mentality.” Distinct, yes. Aggressive, maybe, though nothing compared to the aggressiveness of fundamentalists and homeopaths. Messianic? Here we go again with the projected Jesus complex!

Had he done his homework, he would have found out the answer quite readily: until the very same week of the meetup, New Yorkers had been treated to an inane message of the anti-vaccination movement, displayed in full colors on the CBS billboard in Times Square. But that’s a fact that was much less interesting to Mr. Liu than the type of earring I wear (a black diamond, if you need to know).

ost disclosure statements are not designed to be read; they are designed to be clicked on. But some companies actually want their customers to read and understand the statements. They don’t want customers who might sue, and, just in case, they want to be able to prove that the customers did understand the risks. So the leaders in disclosure statements right now tend to be financial and health-care companies – and also space-travel and extreme-sports vendors. They sincerely want to let their customers know what they are getting into, because a regretful customer is a vengeful one. That means making disclosure statements readable. I would suggest turning them into a quiz. The user would not simply click a single button, but would have to select the right button for each question. For example: What are my chances of dying in space? A) 5% B) 30% C) 1-4% (the correct answer, based on experience so far; current spacecraft are believed to be safer.) Now imagine: Who can see my data? A) I can. B) XYZ Corporation. C) XYZ Corporation’s marketing partners. (Click here to see the list.) D) XYZ Corporation’s affiliates and anyone it chooses. As the customer picks answers, she gets a good idea of what is going on. In fact, if you're a marketer, why not dispense with a single right answer and let the consumer specify what she wants to have happen with her data (and corresponding privileges/access rights if necessary)? That’s much more useful than vague policy statements. Suddenly, the disclosure statement becomes a consumer application that adds value to the vendor-consumer relationship.

And show the data themselves rather than a description.

this is all very easy if you are the site with which the user communicates directly; it is more difficult if you are in the background, a third party collecting information surreptitiously. But that practice should be stopped, anyway.

Literature teaches us about life. Literature helps us understand the world.

this belief in truth-from-fiction is the party line for those who champion the merits of literature. Eminent English professor and critic Harold Bloom proclaims, in his bestselling How to Read and Why, that one of the main reasons to read literature is because "we require knowledge, not just of self and others, but of the way things are."

why would we expect literature to be a reliable source of knowledge about "the way things are"? After all, the narratives which are the most gripping and satisfying to read are not the most representative of how the world actually works. They have dramatic resolutions, foreshadowing, conflict, climax, and surprise. People tend to get their comeuppance after they misbehave. People who pursue their dream passionately tend to succeed. Disaster tends to strike when you least expect it. These narratives are over-represented in literature because they're more gratifying to read; why would we expect to learn from them about "the way things are"?

MIDDLE SCHOOL students are champion time-wasters. And the personal computer may be the ultimate time-wasting appliance.

there is an automatic inclination to think of the machine in its most idealized form, as the Great Equalizer. In developing countries, computers are outfitted with grand educational hopes, like those that animate the One Laptop Per Child initiative, which was examined in this space in April.

Economists are trying to measure a home computer’s educational impact on schoolchildren in low-income households. Taking widely varying routes, they are arriving at similar conclusions: little or no educational benefit is found. Worse, computers seem to have further separated children in low-income households, whose test scores often decline after the machine arrives, from their more privileged counterparts.

The accepted definition of creativity is production of something original and useful, and that’s what’s reflected in the tests. There is never one right answer. To be creative requires divergent thinking (generating many unique ideas) and then convergent thinking (combining those ideas into the best result).

Torrance’s tasks, which have become the gold standard in creativity assessment, measure creativity perfectly. What’s shocking is how incredibly well Torrance’s creativity index predicted those kids’ creative accomplishments as adults.

The correlation to lifetime creative accomplishment was more than three times stronger for childhood creativity than childhood IQ.
