O

O: The intimate history of the orgasm
Jonathan Margolis
Century, 2003

Der Mensch wird auf natürlichem Wege hergestellt, doch empfindet er dies als unnatürlich und spricht nicht gern davon. Kurt Tucholsky, Der Mensch

Every one of the seven billion humans alive today, as well as everybody who has lived before, owes their life to at least one person having an orgasm, as Margolis points out at the end of this book. (Although twins and sperm-donor children may have to share one, I might have added.) When it’s off its reproductive duty, the orgasm is free and healthy, though short-lived fun accessible to most people. So why have dominating cultures and religious creeds demonised it for centuries, insisting that women should feel no sexual pleasure at all, and men should limit theirs to procreation?

Following the cultural history of sexual pleasure – for which he uses “the orgasm” as a shorthand – Margolis gives a broad overview of the shifting attitudes towards it. His history starts off a bit shakily with speculations on stone-age sex, where he repeatedly admits that we don’t really know what went down, but then continues to speculate anyhow.

The writing gets much stronger as soon as the killjoy tendencies of the Christian church start to kick in, which he contrasts with the more liberal attitudes in other cultures including ancient China and India. Margolis argues convincingly, for instance, that the restrictive sexual morals of the catholic church, gradually getting worse as its power grew, also infected other cultures and religions, which started out with a much more relaxed attitude than they have today.

The general perception is that this anti-orgasmic ideology peaked in Victorian times and that things have gradually improved since then, with things like the Kinsey report, the Lady Chatterley trial, and the pill representing the much-cited milestones on our way back to a more natural and reasonable attitude to our own reproductive biology.

Arriving at the present day, one is tempted to think we live in the best of all times and have overcome most of the religious hang-ups. Except that fundamentalism is on the increase, and some of today’s dominating cultural forums play by rules that are downright Victorian. For instance, no breastfeeding pictures are allowed on facebook, and a female nipple on a cinema screen is deemed off-limits for children (who, on the other hand, are allowed to watch people getting murdered). So I wouldn’t quite share the author’s optimism that we’re at the beginning of an age of enlightenment. Things can slip back fairly quickly.

There isn’t much new material or original thought in this work, and it could have done with more thorough editing, but there are lots of lovely quotes and factoids to enjoy along the way, from the pharaohs’ duties in fertilising the Nile with their own seeds to J. Edgar Hoover’s admission that the FBI is powerless against the almighty “oral-genital intimacy.” I am particularly grateful that the author mentioned a book from 1839 with the intriguing title The women of England: Their social duties, and domestic habits. I found that it has actually been re-issued recently and is available to buy.

Thus, as a “review” drawing on a vast range of sources, O is certainly worth reading.

Cover of the Italian edition - very similar to my English edition though.

PS: It is really weird that I seem to have missed this when it came out, especially as I translated/edited Lust and Love in 2004/05, so would have had my eyes wide open for related works. I think it must have been comprehensively ignored by the media around here. I only discovered it a month ago in one of those bookshops where every book is £2. So it was cheaper than the Saturday edition of our newspaper, come to think of it, and it's very good value at that kind of price.

brazilian relatives

Back in 1891, when my great-great-great-great-uncle Christian Gottlieb Weiß wrote up what he knew about his ancestors and relatives, he noted about his aunt:

„Maria Katharina Weiß, geb. 17.2.1786 verh. mit Pfarrer Ried aus Schauern (Hochwald) ist in Rio di jeneire (Südamerika)“

which for a long time was all we knew about that branch of the family. We have now found out, however, that this family emigrating to Brazil has left many dozens of descendants there. They didn’t in fact go to Rio but to São Leopoldo, like a lot of other emigrants from the Hunsrück area did, too. The spelling of the husband’s name is Rieth, and he wasn’t a vicar either.

Helpful fellow genealogists in Brazil sent us a big chunk of data of Rieth descendants, which I’ll summarise the important bits here:

Maria Katharina (or Maria Barbara according to other sources) and her husband Georg Philipp Rieth (1784-1843), together with their two sons Philipp Christian Gottlieb (*1811) and Johann Friedrich (*1814) emigrated in 1829, arriving in São Leopoldo on 25.5.1829.

Both sons married within the community of German migrants from the Hunsrück. Philipp Christian Gottlieb Rieth married Maria Elisabeth Schiehl (born 1820 in Hundsbach near Meisenheim) in São Leopoldo in 1838. Johann Friedrich Rieth, confusingly, married Maria Caroline Rieth (1824-1898), born in Schauren like he was, so more likely than not a cousin. This second Rieth family (the parents are Georg Heinrich Rieth and Johanna Dorothea Schlieper) arrived in São Leopoldo on 29.12.1825.

Each of the two had eleven children, many of whom went on to marry other people from the German community (we find the names Uebel and Purper from Oberstein, Hemb from Niederkumbd, Haag from Sensweiler near Trier), producing more than 40 great-grandchildren for Maria Weiß and Georg Philipp Rieth.

These descendants stayed mostly in the surroundings of São Leopoldo (i.e. in the state of Rio Grande do Sul), settling in places like Lomba Grande, Hamburgo Velho, Sapiranga. In this area, you’ll even find streets and a school named after people with the surname Rieth.

Astrobiologie für Einsteiger

The official publication date for the German edition of Astrobiology - A brief introduction is today (though amazon.de hasn't updated the page yet). Below the picture is a snippet from the preface.

Auszug aus dem Vorwort:

Auf der Grundlage der umfassenden (wenn auch unvollständigen) wissenschaftlichen Erkenntnisse über das Leben auf der Erde stellt die Astrobiologie sich drei fundamentalen Fragen über das Leben im Universum:

• Welche physikalischen Eigenschaften ermöglichen es unserem Universum, Leben hervorzubringen?

• Wie spielte sich die Entstehung und Entwicklung des Lebens auf der Erde ab, und wie verschieden könnte dieser Prozess anderswo abgelaufen sein?

• An welchen anderen Orten im Universum könnte Leben entstanden sein, wie könnte es aussehen, und wie können wir es finden?

Der Wert der Astrobiologie liegt zum Großteil darin, dass diese Fragen vielleicht zu den fundamental wichtigsten Problemen der heutigen Wissenschaft gehören. Sie sprechen grundlegende Bedürfnisse des Menschen an, nämlich, zu wissen, wer wir sind, wo wir herkommen, und ob wir in den Weiten des Weltalls allein sind. Zusätzlicher Nutzen ergibt sich daraus, dass diese Fragen eine ungewöhnlich interdisziplinäre Vorgehensweise erfordern. Die Astrobiologie berührt eine Vielzahl von traditionellen Disziplinen wie Kosmologie, Astrophysik, Astronomie, Geologie, Chemie, Biochemie und natürlich die Biologie. Dieser Umstand verleiht den einzelnen Wissensgebieten einen neuen Grad an Bedeutung, da sie in einem weiter gefassten Kontext eingebettet werden. Andererseits macht die interdisziplinäre Natur der Astrobiologie auch eine reibungslose Kommunikation zwischen weit auseinanderliegenden Disziplinen erforderlich. Es gilt, Astronomie für Biologen verständlich zu machen, und Zellbiologie für Astrophysikerinnen. In diesem Sinne versuchen wir mit diesem Buch, den gegenwärtigen Stand der Astrobiologie einem breiten Spektrum von wissenschaftlich Interessierten, „also Hörerinnen und Hörern aller Fakultäten“ zugänglich zu machen und beschränken uns deshalb auf die notwendigen wissenschaftlichen Einzelheiten.

sea floor surprises

I used to think that our civilisation's lack of knowledge of the deep sea was just embarrassing - as often summarised in the statement (still true, I think) that we know the far side of the moon in greater detail than the sea floor. However, in the course of research for my latest feature, I realised that it is downright dangerous.

The bottom of the ocean is the boundary between the Earth's crust, which is reduced, thus may contain large amounts of methane, and the oxygen-bearing oceans. Microbes ensure that the methane reaching the boundary gets oxidised and metabolised. If it escaped this process and managed to rise to the atmosphere, a climate disaster would hit us that might be even bigger than the one we're currently producing ourselves.

And yet we have very incomplete knowledge of the chemistry going on in sea floor sediments, as two recent, completely unexpected discoveries have revealed - one demonstrating novel redox biochemistry with S(0) intermediates, the other electron transport through bacterial filaments.

My feature is out today in Current Biology:

snow leopards

For my recent feature "Felids fighting for survival" I established contact with the conservation charity Panthera, which specialises on felines. Panthera has now released a new video from the field of a snow leopard mother and cubs in Tajikistan.

Their description: "In true holiday form, the footage shows two snow leopard cubs licking and pawing icicles, attempting to climb a rock, playing, etc. Along with the interactive nature of the footage (and the awww factor), our scientists were pleased to find that it also potentially indicates that a healthy, breeding snow leopard population exists in the Jartygumbez Istyk region of Tajikistan’s Pamir Mountains."

is thorium the answer?

My long essay review of the book:
Superfuel – Thorium, the green energy source for the future.
by Richard Martin
Palgrave Macmillan
ISBN 978-0-230-11647-4

is out in Chemistry & Industry, December issue, pp 46-47.

I didn't know anything about thorium reactors before reading this book, but thought the author made a convincing case. Most intriguing, however, is the unravelling of the history of nuclear technology and the reasons why the reactor type predominant today was chosen. I think it's a fair summary to say that all of them were bad reasons, and a lot of them had to do with military considerations.

A snippet from my review: "It is always interesting to trace back the evolution of technology and work out why one route was taken rather than another. Why did petrol knock out ethanol fuel, when today we’re going back to ethanol? Why did planes that are heavier than air take off and leave the zeppelins behind? In the case of thorium liquid fuel reactors versus pressurized water reactors with solid uranium rods, Martin argues convincingly that the decisions favouring the latter type of technology were made for all the wrong reasons and that they blocked a technology that would today come in very handy as a green solution to the challenges of climate change and energy security."

For balance, note also that Stephen Ashley et al. say in the current issue of Nature that the arms proliferation risk of the thorium technology isn't as small as its proponents claim (Nature 2012, 492, 31).

evolution of writing

Something very scary happened in western Iran around 5000 years ago. People started using a writing system for their bookkeeping, used and developed it for a few centuries, and then stopped writing.

The system they used is called proto-Elamite script, it is obviously inspired by Mesopotamian cuneiform but has mostly developed its own symbols, which aren't completely decoded yet. Decoding it further may help to explain how and why people fell back to illiteracy.

I interviewed the leading researcher specialising in this script, who happens to be based in Oxford, and wrote a feature which is out in Current Biology today. And, writing for biologists, I've given the story a bit of a biological spin, hence the title:

Vermeer's China

Vermeer's Hat: The seventeenth century and the dawn of the global world by Timothy Brook

I raved about this book a few years ago after reading just a review of it - I was so jealous of the idea.

Years later, after laying hands on an actual copy and actually reading it, I'm not quite as excited any more (it may be a sign that I forgot to post the review here after I wrote it in May and posted it on amazon).

The author uses the compact and widely known oeuvre of Vermeer and, particularly, the objects pictured in it as a window into the 17th century world. (Very fittingly, as windows (or more likely, the same window) often feature in these pictures.) There is some great storytelling and intriguing connections between Old Europe, the New World, and China, which in this day and age we are very prone to interpret as the "dawn of globalisation."

I was a little disappointed, however, to find that Brook didn't stick with Vermeer - of the eight works he discusses, only five are Vermeer paintings. As an expert in Chinese history, the author is ultimately more interested in the global trade routes in the 17th century than in Vermeer, and he only uses the painter as a tool to popularise his academic discipline. Of course he has every right to do so, but I'd still be interested in a book that tries to shed light on the story of every object of every single Vermeer painting. There aren't that many, so it should be possible.

tumblr and I

These days I am spending most of my online social networking time on tumblr, which is ironic, as it took me well over a year before I got the hang of it.

I had been homeless on the web since MySpace turned into a ghost town and the forums I had visited also died at around the same time – probably all due to the unstoppable rise of facebook. While I’ve been able to transfer quite a few of these contacts to facebook, I never really liked spending time there. In 2010, I signed up to twitter, which I like a lot, but it is a medium more than a place. I can use it to widen the audience for blog entries (on blogspot) or photos (on flickr), but if I spend more than five minutes watching my twitter timeline (following some 1600 people!), the futility and randomness of it gets to me. Unless there is some major political scandal to kick around, which is always fun on twitter. (I also tried google+ but that never took off, and I am registered with LinkedIn, but it bores me to tears.)

So, well, tumblr and I started out on the wrong foot. I signed up in June 2011 when somebody whom I knew from mutual blog-following on blogspot moved her blogging activity to tumblr and I wanted to stay in touch. However, she soon succumbed to the temptation of the NSFW blogs available on tumblr and ended up reblogging that kind of stuff endlessly without posting anything of her own.

In the first months I didn’t come across any individuals who were actually posting their own content. Everything I saw back then seemed to be just swirling round in circles (which I guess is where the name tumblr comes from?) and come from unattributed sources, i.e. probably stolen. Using tags like #science I found some vaguely interesting blogs that I still follow, like the mother nature network, which covers science and environment, but that didn’t really pull me in.

The legacy of my very first contact in tumblr meant that I had no shortage of addresses for erotica, but once I eliminated all peniswaving blogs, I was left with a few lesbian ones (which I still love) and one that systematically reblogs “topless Tuesday” photos. For a few months I just let these float by, but at one point I started to wonder who these women were. If I liked the face above the boobs I looked up the blog and found quite a few interesting people who – and that was rather important to me – did post their own content, rather than just reblogging all the time.

Some of them even very kindly followed me back, so by that stage – perhaps 1 year into the experience - I had around 20 followers (as many as my blog on blogspot has, except that I don’t think that anybody still checks the blogs they follow there). That gave me a little bit more confidence to expect that somebody, at some point might actually look at contributions I post, so I systematically posted links to my articles and blog entries from blogspot. That helped a little bit, some people became interested in the science bits I had to offer.

Then I widened my spectrum, discovered that there is a one-click option to share my flickr photos on tumblr, also posted the odd video, and ended up sharing everything I posted elsewhere (blogspot, twitter, flickr, facebook) on tumblr as well, and more. By the beginning of this month, the increased activity succeeded in attracting new followers on a daily basis, and catalysing new friendships in a way that I hadn’t really experienced since the demise of myspace.

Tumblr really has become a place on the web where I like to spend time, where I’m surrounded by people who I like, even if they are still mostly strangers. I find it amazing how openly people communicate about very intimate problems over there, and how supportive and loving most people are (apart from some anon. trolling – personally I’ve switched off anonymous asks, so I don’t have that problem). I’m beginning to worry that this is too good to last and that Murdoch might soon buy it up and ruin it (this irrational fear will in the future be called the MySpace trauma). I'm just hoping it stays exactly as it is.

how the croc got its teeth

Last month, en route to a family visit, I stopped by at the Institut de Genomique Fonctionelle de Lyon (IGFL) and learned lots of exciting things about the research they're doing there, connecting physiology, evolution and development with the help of genomics. Essentially, how does a string of DNA turn into a living breathing animal? How did the leopard get its spots, and the croc its teeth? (Disclaimer: they don't do leopards in Lyon, as far as I know, but they have got answers for the croc question!)

There was too much to mention everything but I tried to make a meaningful story out of this, which is out in today's issue of Current Biology:
