Brainy stuff

Pinkish grey and vaguely reminiscent of an oversized walnut, the human brain is composed of brainy stuff, which allows it, by means that are far from fully understood, to do brainy stuff. Currently screening on BBC Four TV this week (and available on iPlayer) this year's Royal Institution Christmas Lectures are delivered by Professor Bruce Hood, who is inviting us to "Meet Your Brain".

Here's a trailer, from the RI Channel website:

The Christmas Lectures 2011 - Trailer from The Royal Institution on Vimeo.

There are lots more videos relating to the Christmas Lectures on the RI Channel, including some snippets recorded well before the lectures themselves. Worth a browse.

As an unexpected bonus, Professor Hood's new book The Self Illusion — not due to be published until April 2012 — is partly available as a free Kindle download from Amazon (remember you don't need a Kindle to be able to read Kindle ebooks — there are free software readers for Mac, Windows, iOS and Android).

The last time brainy stuff was the subject of the Christmas Lectures they were delivered, if I remember correctly, by Susan Greenfield. Presumably she went on to carry out rigorous, detailed research — fully documented in respected peer-reviewed scientific journals — into the effects on the brain of activities such as video-gaming and internet social networking. Or something like that.

Uncaged Monkeys at the Anvil, Basingstoke

"So what's this Uncaged Monkeys thing you're going to see then? Is it a band?"

"No, it's not a band."

"A play?"

"No, it's ... science. And comedy."

"Oh. That sounds —"

"By the people in Radio Four's The Infinite Monkey Cage. You heard of that?"

"Er, no."

"Well, they just got a Sony Award."

It may have been different, geeky, at times hilarious and at other times intensely moving. It may not be the usual fare at the Basingstoke Anvil, but it filled pretty well all of the hall's 1400 seats.

Robin Ince started the show off, casting some aspersions on Professor Brian Cox — whom he claimed never listened to the introductions so he could say what he liked. Then it was time for TV's Professor Wonder Boy to wow us with potted particle physics. He hit us with the Higgs boson, and claimed that particle accelerators were always built near airports in order to give them a sense of perspective. In a generally reassuring manner he touched on the likelihood of the Large Hadron Collider destroying the Earth, using a technical term that I forget — though I remember it was four letters beginning and ending in "t". (There was also a "w" and an asterisk in it somewhere). He showed us a graphic of government funding, challenging us to locate the spend on scientific research. He pointed out the bill for the bank bail-out, and that it was greater than the amount spent on science ... since Jesus. And he did the Big Bang.

Ben Goldacre chased his wild hair and oscillating eyebrows around the stage, with tales of placebos, big pharma and fish oil pills, and he showed us a picture of his cat Henrietta, plus a certificate of her medical qualifications — the same qualifications claimed by nutritionist Gillian McKeith. Great mirth ensued, but the stuff about big pharma was actually quite worrying.

Steve Jones talked about evolution, illustrating natural selection with something from his own early career as an engineer. His example was a process of converting a liquid to a powder by forcing it at high pressure through metal nozzles. Apparently these nozzles used to corrode and become ineffective very quickly. Rather than try to work out the best shape for these nozzles, the designers used a form of random mutation, making ten copies, each slightly — but randomly — different from the original. These copies then were tested, and best one was then randomly mutated ten times and then those copies were tested. After several cycles of such random mutation and selection, they ended up with a nozzle that lasted 100 times longer than the original, but no-one knew why.

Simon Singh electrocuted a gherkin on stage, which was highly illuminating (literally, though what it would taste like after that, he didn't say). Of such insights is the scientific knowledge regarding the size and the age of the universe derived. And he too did the Big Bang. He ended with the story of his somewhat pedantic insistence on the accuracy of song lyrics, which is appropriate because we were also entertained by Helen Arney, who sang to us while playing the ukele.

There was a session during which Robin Ince passed on tweeted questions to Ben Goldacre, Brian Cox and Simon Singh. (There is also a podcast — Free Primates — in which the Uncaged Monkeys answer questions they didn't have time to deal with on stage.)

Naturally the show could not pass without several mentions of Carl Sagan, of whom both Robin Ince and Brian Cox are declared fans. Sagan's Pale Blue Dot brought the proceedings to a moving close.

Altogether it was a splendidly enjoyable evening, and I saw the whole thing close up as I was on the front row. What I should have realised is that the Anvil is the nearest venue for many of those people who attend Winchester Skeptics in the Pub, as well as the fledgling Portsmouth Skeptics in the Pub. Several were indeed attending, and I was pleased to be able to join some of them for a curry after the show.

James Randi at TAM London 2010

TAM London's first day's talks concluded with the man himself, James the Amaz!ng Randi, who was interviewed on stage by Robin Ince. He talked about his skeptical origins and some of his encounters with so-called psychics, mediums and faith healers. It was clear that Randi's preoccupation with such people is not merely idle interest but an abiding passion. They may be deluded about their "powers" or they may be out-and-out charlatans; Randi has encountered both extremes and everything in between, and in all cases he is dedicated to exposing them for what they are, not least because they mislead innocent people who pay good money for something that isn't real.

It was inspiring to hear Randi speak live about his life in skepticism, but if I have one niggle it would be that he and Robin Ince should have swapped places — Randi was positioned on stage such that he gazed mostly off to the side, away from the camera producing the view that filled the big screen.



After his discussion with Robin Ince, Randi presented two awards. The TAM London 2010 award went to Ben Goldacre, who accepted it by pre-recorded video. Ben was unable to accept the award in person, but the video was an unexpected bonus — it initially freeze-framed, giving us a static second or two of typical zany Ben Goldacre expression. (And check out what must be the geekiest bookcase ever....)



The second award was for Grassroots Skepticism, and went to Rhys Morgan for his single-handed stance against quack-remedy "Miracle Mineral Solution", which despite being basically bleach, has been promoted as effective against ... pretty much anything except amputation. Rhys has Crohn's disease, one of the huge list of afflictions that MMS is claimed to cure, and it was this that led him to investigate it, and subsequently to campaign against it. Such activism is to be commended in anyone, and so the award is richly deserved — more so in this case as at the time Rhys was only 15 years old.

Japan earthquake — and responsible journalism

I've been at work all day and busy in the evening, so I've only caught glimpses of the news reports coming from Japan, but the TV pictures I've seen so far look horrendous. A natural disaster is obviously a hot topic, and a lot is written about it — not just dealing with the disaster itself, but also concerning related speculation, perhaps about the frequency of such events, their causes, and what can be done — if anything — to anticipate them, and to mitigate their effects afterwards.

I appreciate that it may be hard for a newspaper editor to come up with a unique perspective on an event like today's earthquake in Japan and its resulting tsunami. I appreciate that a paper needs to have something special to offer its readers — a reason why they should read this paper rather than another. But I am at a loss to understand the mentality of an editor who approved the publication of this:

(Via @bengoldacre's posterous)

It's clear from the article that the Mail knows that this "astrological prediction" is entirely bogus. And yet it publishes this despicable, tasteless and inconsiderate nonsense in the face of massive destruction and potentially enormous human suffering.

I ... words fail me.

Protest the Pope — speeches roundup

Here are some links to recordings of the "Protest the Pope" rally that took place in London last Saturday. The first video (for the attention-challenged) is edited highlights, beginning with Geoffrey Robinson and including Richard Dawkins, Barbara Blaine, Peter Tatchell, Maryam Namazie, Andrew Copson and Johann Hari:

The Pod Delusion folks have made available an unedited audio recording of the speeches. While the sound quality isn't great, for those like myself who did not attend the rally the recording does serve to put all of the above clips in sequence and context:

BBC investigates life-threatening teachings of nutritionist

The woo just goes on and on...

http://www.youtube.com/watch?v=aXaS_5AXJ0g


This is a clip from last Wednesday's Inside Out England TV programme* on BBC1; the segment is about Barbara Wren, who teaches courses on nutrition at her College of Natural Nutrition (the domain name for which is abbreviated with total lack of irony to "natnut.co.uk"). The BBC's investigation indicates that her teachings are not only unscientific but also life-threatening.

The clip is also available on the programme's web page, and the whole 30-minute programme is available for a limited time on the BBC iPlayer.

(*It turns out that this programme was a repeat, and was blogged by Professor David Colquhoun at DC’s Improbable Science.)

When I started writing this blog-post I considered making a point about how this kind of non-science might be about to fade away under the persistent scrutiny of investigations like this BBC TV programme. But after spending only a few minutes on Google I found that the amount of seriously misguided belief in such nonsense - as well as this nonsense in particular - remains large and widespread. It needs attention.

You've read the Bad Science blog, now buy the book

For some years I've been suspicious of mainstream media. Almost everyone I know who has had even the tiniest bit of media coverage has told of some distortion, misrepresentation or downright lies (um ... I mean, things reported as facts when they're not). Reading articles about matters on which I do have some expertise, I've been struck by the preponderance of inaccuracies. So the idea that the media don't tell the truth, the whole truth and nothing but the truth isn't new to me, as it probably isn't new to anyone. And though I've been reading Ben Goldacre's blog for over a year now, and on that basis was looking forward to reading his book, I wasn't prepared for the sheer scale of misrepresentation he so clearly and entertainingly documents in Bad Science (Fourth Estate, 2008).

He has a chapter (7) entitled "Dr Gillian McKeith PhD" in which he deconstructs the scientific pronouncements of a media nutritionist who is, apparently, a "prime-time TV celebrity", with a Channel 4 show entitled You Are What You Eat. Her name wasn't familiar to me, though I recognised the title of the show even if I'd never seen it. (I don't watch 'make-over' or similar shows - I find them embarassing and voyeuristic, especially with the modern trend of treating participants like recalcitrant schoolchildren.)

Goldacre's indictments of McKeith are damning and comprehensive, and given that (as I understand it) his book is a compendium of his Guardian columns and his blog posts, I imagined that McKeith would by now have been consigned to the media scrap-heap. But just to check, I did a little internet research, which yielded so many results that I found myself skimming the latest edition of Radio Times, to discover that You Are What You Eat was currently showing daily in an early morning slot on More4. As it happened I was due to leave the country for a few days, so I set my DVR to record a week's worth of these half-hour programmes in my absence.

I watched them back-to-back on my return (though I did fast-forward parts of the fourth and fifth, as the repetitious format had by then become seriously grating). What Goldacre says in his book is true - McKeith appeared to be obsessed with faeces and colonic irrigation, and repeatedly came out with scientific-sounding stuff for which there is no proper evidence. The programmes were strictly formatted to the point of tedium, and I was frankly amazed that they were still on TV.

Bad Science covers a lot of specifics, from the absurdities of Brain Gym to the scandal of the MMR vaccine scare - and nearly all of them are initiated, compounded and perpetuated by ill-informed and inexpert media. On the way through this quagmire of dumbing-down headlines Goldacre gives us primers on statistics, probablility, evidence-based medicine and ethical journalism. Anyone who reads the badscience.net blog will be aware of Goldacre's journalistic light touch, and will therefore be clamouring for a copy of this book.

For my own part, not since reading Carl Sagan's The Demon-Haunted World have I found a book so enlightening.
