“Marriage saves lives!” (Well, it has a nice ring to it…)

So, apparently, being married is good for you. Married, I tells ya, as in party to a matrimonial contractual arrangement with a legally eligible spouse. Why might this be? Well, one advantage to being married is that your tax and inheritance provisions tend to be facilitated by legislation in ways that materially advantage you over non-married folk. And if you are inclined toward such stuff, you may also expect your relationship will be spiritually blessed by whatever deity you think morally underwrites your existence.

But what you mightn’t count on are the associated medical benefits. And quite specific ones at that. Because, according to several media reports this week, scientists have now revealed that “being married” makes you twice as likely to be alive 15 years after heart surgery. Or three times as likely, if you read a different media website. Or four times as likely if you read another. Whichever, it seems like quite a lot. Put the other way around, it means that not being married makes you only half, a third, or a quarter as likely to survive as someone who has been wedded in holy (or civil) matrimony.

It was a pretty simple message; so simple, in fact, that the media ended up gravitating toward a relatively narrow repertoire of similarly worded headlines. The LA Times went with ”Marriage helps the heart“, while CBS News had ”Marriage tied to longer survival after heart bypass“. Both USA Today and CNN came up with “Marriage helps survival after heart surgery“. Meanwhile, some of the more socially conservative outlets emphasized the importance of having a cohesive marriage: “Take Heart! A good marriage protects even after a bypass” proclaimed Fox News; while the Christian Post declared that “Healthy marriages lead to healthy hearts“. And these pronouncements were not intended as social value-statements moderated by conservative editorial stances. No, science told us that all this is so, apparently.

Except it didn’t, of course. Continue reading

No, you are NOT worth it

When it comes to questionable science claims in advertising, you rarely need to look further than the cosmetics industry. Just two weeks ago, two magazine advertisements by French cosmetics giant L’Oréal were banned by Britain’s Advertising Standards Authority following a complaint by a Member of the UK Parliament. The ASA found that L’Oréal had misleadingly airbrushed photos of Christy Turlington and Julia Roberts in a way that exaggerated the purported enhancing effects of two of its foundation products. In both cases, the claims being made were explicitly scientific, ones that clearly implied a basis in research-sourced empirical evidence.

The pic of Christy Turlington was alleged to support the claim that the product could produce a “natural light” from human skin, and that this effect had been established following “10 years of research“. In their submission to the ASA, L’Oréal said their research had focused on “the optical properties” of skin, and on how to “reinforce the skin’s radiance” and “improve its ability to reflect light“. Meanwhile the photo of Julia Roberts was used to show how another product had been developed to exert “anti-aging” effects.

The ASA, however, felt that all this was bunkum, and banned the ads. Continue reading

Shock! ‘Rise of the Planet of the Apes’ is scientifically implausible


I’ve just returned from watching Rise of the Planet of the Apes at my local cinema, and I’m happy to report that there were no scientific shortcomings or flaws whatsoever in this movie.

ONLY KIDDING! While it is certainly an enjoyable flick, and boasts terrific visual effects (especially once all the argy-bargy kicks off in the third act), its scientific aspects are indeed a little confused. Now, I’m not naïve: I realise that a movie that portrays the rise of a domineering superspecies of genetically modified ape is unlikely to be wholly realistic. And as well as the overarching fantasy, I am more than happy to accept some of the more trivial scientific anomalies, such as the idea that a few hundred nonhuman primates — species that breed very slowly (maybe one offspring per couple every four or five years) — can threaten to outpopulate humanity itself any time soon.

But what does irritate me a little about the movie is its strapline: ‘Evolution Becomes Revolution‘. Because it is pretty obvious that, while revolution might be apparent, what preceded it was not evolution. At least not in this movie. In fact, the central plot device here runs so counter to the principles of evolution that it appears to belie even Victorian-era biological science. In other words, it pre-dates Darwin.

“Extraordinary people, ordinary evidence”

Here’s just something for the archives. I rarely write book reviews nowadays (although I often get invited to do so), partly because they can become extremely time-consuming. After all, to be fair to the book’s authors or editors, you do need to actually read the book in question before reviewing it (a principle that, as far as I can tell, does not command universal adherence). Of course if the book is terrific, then that’s no problem; you’d be glad to read it anyway whether or not you were invited to write a review. But if the book is poor, then things become uncomfortable; reading it to completion and then writing the review can be extremely tedious indeed. Continue reading

See no evil, hear no evil…

If you were confused by last week’s media stories about the latest review of UK science research on monkeys, then you are forgiven. The review, commissioned by the major British science funders and chaired by the president of the Zoological Society of London, evaluated 10 years of research involving non-human primates (NHPs) with a brief to establish whether or not such work was justified. Not a terribly vague objective, you might think, although perhaps a complex one. So what did they conclude, exactly? Well, according to some media headlines, NHP research was found to be little more than monkey business. For example, according to the Daily Telegraph, “Most experiments on monkeys have little medical benefit“. Now that certainly sounds bad: the Telegraph are telling us that the majority of NHP studies were medically useless. However, the Guardian presented quite a different arithmetic: “One in ten research projects using monkeys has no benefit, finds review” was their headline. One in ten, eh? That’s quite a lot. But it’s by no means the majority. So what exactly is going on? And are the Review Group’s findings reliable? Continue reading
