Data from Kaguya's prime mission to the Moon has been released
'Yesterday, the Japanese space agency announced the public release of the data from the primary mission of the Kaguya (a.k.a. SELENE) lunar orbiter. The release covers the period from December 21, 2007 to October 31, 2008, and includes data from all of the science instruments (which excludes the HD camera, not a science instrument). This release formally opens up the data for use by all scientists and enthusiasts around the world, not just the Kaguya science team, and will be a rich resource for lunar scientists.'

Speed Limit To The Pace Of Evolution, Biologists Say
'Researchers at the University of Pennsylvania have developed a theoretical model that informs the understanding of evolution and determines how quickly an organism will evolve using a catalogue of "evolutionary speed limits." The model provides quantitative predictions for the speed of evolution on various "fitness landscapes," the dynamic and varied conditions under which bacteria, viruses and even humans adapt.'

Mass extinction blamed on fiery fountains of coal
'FOSSIL fuels have a new crime to live down.

Neutered HIV Virus Delivers Treatment to Fatally Ill Boys
'Researchers may have taken a step towards curing the rare, inherited brain disease made famous by the movie Lorenzo’s Oil–and also towards ushering a new era of gene therapy. To help two young boys suffering from the disease, researchers tried an experimental treatment using a deactivated version of the HIV virus. The virus delivered working copies of a gene to stem cells from the patients’ bone marrows. The HIV virus, stripped of genetic material that makes it toxic, integrates permanently into the DNA of cells it enters, scientists said. That means the modified gene remains in the blood-forming stem cells for the life of the patient.'

2012

Fulfills every expectation of a Roland Emmerich disaster flick: big, noisy, national monuments in the firing line, totally infused with Emmerich's talent for presenting spectacular CGI destruction as flatly as Powerpoint, and killing billions of people and failing to make you care for any of them. But if it's dumb spectacle you want, he's your man, there's a nice twist in the story, and I can't help but having a sneaking regard for a film whose hero is a failed SF writer.

Most interesting aspect of these films, for me, is the use of found media footage to titivate the mise en scene. We're already in the middle of an apocalypse, and like the frog in the pot on the stove, don't realise the water is growing fatally warm.

Bonus Awful Warning: the Stephen Somers remake of When Worlds Collide due next year: 'Alpha Centauri is on a collision course for Earth, and mass hysteria of biblical proportions breaks out in the streets...'

Science Fiction That Isn't Science Fiction (3)

Roland Emmerich’s 2012 claims to be inspired by ancient Mayan prophecies, but with its lovingly detailed CGI shots of the destruction of the temples of Mammon and saving of a small band of the blessed, it’s actually square in the Christian apocalyptic tradition - something that’s almost as old as Christianity itself. The last book in the Bible, the Book of Revelation (also known as Apocalypse, from the verb apokalypto, to reveal), was written towards the end of the first century AD. It’s a visionary warning of the End Times, when the damned will flock to the AntiChrist, the Earth will be visited with every kind of destruction, and true believers will at last ascend into the infinite bliss of the New Jerusalem. Outbreaks of apocalypse fever have swept through Christianity ever since, peaking around 1500, when dozens of sects proclaimed the coming of the End Times (see Norman Cohen’s The Pursuit of the Millennium), and again around the end of the last century. Millions of premillennialists (especially Evangelical Christians in the United States; one of the Founding Fathers, Cotton Mather, was an ardent premillennialist) still expect at any moment to experience the Rapture of bodily ascent into Heaven as a prelude to the harrowing of Earth by a returned Christ.


This apocalypse is the subject of Victorian painter John Martin’s ‘The Great Day of His Wrath’ (above); this, and other huge, sensationalist canvases, were allegedly inspired by commercial dioramas animated by use of artificial lighting - precursors of present-day blockbuster movies. While Martin’s themes were biblical, most of the apocalypses in Hollywood movies are secular,with nuclear war, asteroids, or Arnold Swarzenegger as substitutes for God’s wrath. But an outfit outside the Hollywood machine, Cloud Ten Pictures, has been making movies for a Christian audience that deploy the tropes of premillennialism with deadly seriousness. They’ve produced a trilogy based on the bestselling Left Behind series of novels by Tim LaHaye and Jerry B. Jenkins, a literal portrayal of the End Times of the premillennialists, as well as several thrillers that share the same post-Rapture setting, as well as the same villain, UN President Nicolae Carpathia, aka the AntiChrist (played by Gordon Currie - what must his fan mail be like?): Revelation, Apocalypse, and Tribulation (starring Gary Busey and featuring Margot Kidder and Mr T as, er, Mr T).

They look like science fiction, or science thrillers, but they aren't. As far as the people who made them and their intended audience are concerned, they embody a literal truth.

Plume Run

The Cassini Orbiter completed its seventh close encounter with Saturn's small but highly active moon Enceladus yesterday, passing within a hundred kilometres of the south pole and ploughing through the plumes of water ice fired into space by some as yet unknown process deep beneath the surface. For much of the pass, Cassini was using various instruments to sample the plume, but it took pictures before and after the encounter; Emily Lakdwalla has pasted a couple of the best images in her blog over at the Planetary Society's site, including one of fissured and folded terrain that reminds me all over again that despite its small size, just five hundred kilometres in diameter, Enceldaus possesses an extremely varied and geologically active surface. It's easy to imagine climbing one of those ridges and looking out at a tangle of long, low bright hills snaking towards the sharply curved horizon . . .

Science Fiction That Isn't Science Fiction (2)

At first, when death appeared improbable, because it had never visited him before, Knight could think of no future, nor of anything connected with his past. He could only look sternly at Nature's treacherous attempt to put an end to him, and strive to thwart her.

From the fact that the cliff formed the inner face of the segment of a huge cylinder, having the sky for a top and the sea for a bottom, which enclosed the cove to the extent of more than a semicircle, he could see the vertical face curving round on each side of him. He looked far down the facade, and realized more thoroughly how it threatened him. Grimness was in every feature, and to its very bowels the inimical shape was desolation.

By one of those familiar conjunctions of things wherewith the inanimate world baits the mind of man when he pauses in moments of suspense, opposite Knight's eyes was an imbedded fossil, standing forth in low relief from the rock. It was a creature with eyes. The eyes, dead and turned to stone, were even now regarding him. It was one of the early crustaceans called Trilobites. Separated by millions of years in their lives, Knight and this underling seemed to have met in their death. It was the single instance within reach of his vision of anything that had ever been alive and had had a body to save, as he himself had now.

In this scene from Thomas Hardy’s third published novel, A Pair of Blue Eyes, Knight, a geologist, has just saved the woman he loves and now finds himself hanging from a precarious ledge high on a Cornish seacliff. It's not only the prototypical cliffhanger, dutifully replicated in just about every Hollywood action film; it's also an early instance of another kind of vertiginous thrill: the abrupt contrast between ordinary human life and deep time that creates the famous 'sense of wonder' science fictional affect.

Hardy is best known for his Wessex novels, which mythologise a large swathe of south and south-west England where rural life embedded in landscape and its rhythms and seasons is undergoing changes forced by industrialisation. But at the time of writing A Pair of Blue Eyes, the early 1870s, Britain was in the throes of a scientific revolution too. Darwin's evolutionary theories threatened to displace mankind from the centre of creation; and geology and paleontology were opening up vast backward and abyssal vistas of time. Confronted by the dead gaze of the trilobite, Knight is immediately plunged into a vivid vision of scenes from the history of life on Earth that wouldn't be out of place in an SF novel:

Time closed up like a fan before him. He saw himself at one extremity of the years, face to face with the beginning and all the intermediate centuries simultaneously. Fierce men, clothed in the hides of beasts, and carrying, for defence and attack, huge clubs and pointed spears, rose from the rock, like the phantoms before the doomed Macbeth. They lived in hollows, woods, and mud huts--perhaps in caves of the neighbouring rocks. Behind them stood an earlier band. No man was there. Huge elephantine forms, the mastodon, the hippopotamus, the tapir, antelopes of monstrous size, the megatherium, and the myledon--all, for the moment, in juxtaposition. Further back, and overlapped by these, were perched huge-billed birds and swinish creatures as large as horses. Still more shadowy were the sinister crocodilian outlines--alligators and other uncouth shapes, culminating in the colossal lizard, the iguanodon. Folded behind were dragon forms and clouds of flying reptiles: still underneath were fishy beings of lower development; and so on, till the lifetime scenes of the fossil confronting him were a present and modern condition of things.

Hardy and other late Victorian novelists were concerned with both human individuality and the problems thrown up by industrialisation, urbanisation and scientific revolution. But after modernism overwhelmed the realists, and rejected the authority of science along with that of God and government, SF moved in to take up arguments and themes that have only just been rediscovered by the mainstream.

Science Fiction That Isn't Science Fiction

Millions of years may elapse, hundreds of thousands of generations be born and die, but inexorably the time will come when the declining warmth of the sun will no longer suffice to melt the ice thrusting itself forward from the poles; when the human race, crowding more and more about the equator, will finally no longer find even there enough heat for life; when gradually even the last trace of organic life will vanish; and the earth, an extinct frozen globe like the moon, will circle in deepest darkness and in an ever narrower orbit about the equally extinct sun, and at last fall into it. Other planets will have preceded it, others will follow it; instead of the bright, warm solar system with its harmonious arrangement of members, only a cold, dead sphere will still pursue its lonely path through universal space. And what will happen to our solar system will happen sooner or later to all the other systems of our island universe; it will happen to all the other innumerable island universes, even to those the light of which will never reach the earth while there is a living human eye to receive it.

51̊28'38"N 0̊00'00"E

To Greenwich and the Royal Observatory on Friday, to take part in a discussion about ‘whether science fiction authors are wasting their time writing about interplanetary travel, space colonisation and the spread of mankind across the universe given everything science has taught us about the realities, possibilities and costs of doing so’. The answer to which is of course no, they are not, but I hope the various ramifications and byways my colleagues and I explored were sufficiently entertaining to the small but perfectly formed audience. The organisers may have been a tad optimistic to expect large audiences for the three panel discussions and the screening of Star Trek which were all running at the same time, but I can’t fault the location: our event took place in the circular library at the top of the observatory - the place where the telescope used to be housed, in fact. The round table at which we sat (with an inlay indicating true north) was directly beneath the dome that once opened to the night sky; there were some fine brass telescopes, astrolabes and other instruments in glass cabinets, and all kinds of wonderful books on the shelves running around the room.

The Royal Observatory is also the location of the Prime Meridian, where longitude is 0̊, the dividing line between east and west. Its location is arbitrary, defined by Sir George Airy in 1851, ratified by the International Meridian Conference in 1884 and observed by international convention (although not by everyone, to begin with; the French continued to use the Paris Meridian for a number of years). Appropriate then, that our panel discussion several times touched on the arbitrary division between science fiction that’s based on what’s possible, and science fiction that uses traditional but implausible tropes such as aliens and faster-than-light travel, reminiscent of a recent declaration by Margaret Atwood that she writes speculative fiction rather than science fiction, defining the difference between the two with her usual laser-like precision:

Speculative fiction encompasses that which we could actually do. Sci-fi is that which we’re probably not going to see. We can do the lineage: Sci-fi descends from H.G. Wells’ War of the Worlds; speculative fiction descends from Jules Verne’s Twenty Thousand Leagues Under the Sea.

I’m sort of sympathetic to Atwood’s need to avoid the science fiction tag (she believes that being defined as an SF writer would be the kiss of death to her career as a literary novelist), but her distinction between ‘speculative fiction’ and ‘sci-fi’ is not only as arbitrary as locating the Prime Meridian at 51̊28'38"N 0̊00'00"E, but is completely wrong-headed.

Obviously, novels about Martian invasions lie on the far side of the improbability, but it’s not always easy to predict what we’ll be able to do in the future. Who, in the nineteenth century, could have predicted that their great-great-grandchildren would be able to teleport photons, calculate the number of universes in the multiverse, or create black holes? These seem fantastical even now, yet they are as plausible as Verne’s deep-ocean submarine - if not more so, given that the Nautilus was coal-fired.

Wells’s The War of the Worlds is a realistic depiction of what we in the twenty-first century know must be a fantastical event - the invasion of Earth by Martians. We know now that the only Martians that might plausibly exist are some kind of bacteria or archaeobacteria because observations of the planet from orbit and from the surface have conclusively demonstrated that it is incapable of supporting advanced forms of life. But when Wells wrote The War of the Worlds, in 1898, there was a strong strand of scientific opinion that Mars was not only habitable, but inhabited. In 1877 the Italian astronomer Giovanni Schiaparelli observed patterns of lines on Mars which he called ‘caneli’ - channels. Twenty years later, Percival Lowell argued that these channels really were canals, part of an irrigation network built by an ancient civilisation to transport water from the polar caps. He and others also claimed to have observed seasonal advance and retreat of vegetation across the surface of Mars. In the late nineteenth century, then, it was not at all fantastical to write about Martians because belief that some kind of life existed on Mars was commonplace.

Of course, even though some scientists in the late nineteenth century believed that there might be Martians does not mean that, when it was published, The War of the Worlds could have been included in Atwood’s speculative fiction category. There was no absolute evidence that Martians existed; photographing or dissecting a Martian was not something that scientists could actually do. (Although the Martian heat-rays, then fantasy, now are not.) But it’s a trivial exercise to think of novels that were once ‘speculative fiction’ but are now ‘sci-fi’ simply because the science or universally held assumption on which their speculations were based has since been disproved. One of the tropes in Atwood’s latest novel, The Year of the Flood, is the creation of weird new hybrid species of animals and plants by genetic engineering. But while that seems a pretty probable development of current science, we can’t predict with absolute certainty that one day splicing parts of two different genomes together may be routine. We already know that genomes aren’t simple instruction manuals but are highly dynamic and packed with delicate checks and balances, and there’s now experimental evidence that rewinding evolution and deriving ancestral forms from modern genomes is far more difficult than was formerly believed. What was once rock-solid speculation too often melts into thin, thin air.

In any case, defining novels by a single characteristic - how realistic they are, how close they are to things we can actually do - is dangerously simplistic. The War of the Worlds is not just about a war of the worlds; at the heart of its narrative is a lesson in hubris founded on a powerful and unsettling scientific truth. Wells makes a famous comparison in the opening paragraph of his novel:

No one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man's and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinised and studied, perhaps almost as narrowly as a man with a microscope might scrutinise the transient creatures that swarm and multiply in a drop of water.

Wells studied biology under Thomas Huxley, who rejected current ideas of vitalism and strongly (and correctly) believed that all characteristics of living creatures could be explained by interactions between their constituent chemicals, and was a ferocious and famous supporter of Darwinism (he coined the term). And the idea that most strongly informs The War of the Worlds is not the possibility of life on other worlds, but Darwin’s theory of evolution. If life could evolve on Earth, Wells argues, then why not on Mars? And if there are two separate kingdoms of life, what would happen when one contacts the other?

The war of the worlds is not a war between Martians and men, but an extreme example of the struggle for existence that has shaped the evolution of every species on Earth. Human beings are incidental to the struggle. They are collateral damage. Wells has his Martians land in England when it is at the height of its pomp: the centre of the British Empire, the largest ever known; the epitome of industrial enterprise and scientific innovation. Yet the combined might of the British armed forces is swatted aside by the Martians, English civilisation is swiftly reduced to anarchy, and in the end the Martians are not defeated by microscopic bacilli to which, because they are from another world, they have not evolved resistance.

The epigraph of The War of the Worlds, taken from Kepler’s The Anatomy of Melancholy,* asks ‘how are all things made for man?’ Wells’ answer is that the world and all that is in it is not made for us at all; that the belief that, by divine right, we are masters of the world and the apex of creation is a false and dangerous illusion. That’s the heart of his novel, and we know that it is as true and real as television. Against that, the so-called difference between speculative fiction and sci-fi is trivial indeed.

*EDIT: Oops, actually a quotation from Kepler used by Burton in his The Anatomy of Melancholy, and then borrowed by Wells. Thanks to Cosma for spotting it.

Yesterday's Future Today

Here's an exciting example of cutting edge medical science, combining a clever molecular biology technique with a race-against-time detective story:

In a dramatic illustration of the power of emerging genetic technologies, Yale University researchers have reported making a clinical diagnosis for the first time using comprehensive DNA sequencing of all the protein-coding genes in the genome. The information changed the course of treatment of a baby boy suffering from symptoms of dehydration thousands of miles away in Turkey.

The baby boy presented symptoms that suggested he was suffering from a genetic condition affecting the way his kidneys functioned. Researchers extracted DNA from a small blood sample and applied a technique, whole exome sequencing, that analyses the small percentage of the genome that contains exons. Exons are stretches of DNA in genes that code for the sequences of amino acids that make up proteins. In eukaroyotes (basically, any organism with a cell nucleus), exons are separated by long stretches of DNA, introns, that don't code for amino acids in proteins. Genomes also contain huge amounts of so-called junk DNA between functioning genes, as well various other kinds of non-amino acid coding DNA. As a result, the DNA that codes for proteins makes up just 1% of the human genome, so a technique that exclusively reads exons saves a lot of time and money, and can quickly and accurately pinpoint mutations.

To cut a long story short, the researchers found that the mutation wasn't, as first suspected, the one that causes a rare condition known as Bartter syndrome, but affected a gene that regulates uptake of chloride and water by cells lining the gastrointestinal tract. Since most (but not all) genetic diseases are caused by mutations in the exome, this has all kinds of implications for fast, rapid, and accurate diagnosis of many diseases, and could help unravel the kind of complex syndromes that Dr Gregory House deals with on a weekly basis.

I'm especially interested in this not only because it is a very clever and neat technique, but it's also a powerful illustration that the future is a lot closer than we think. Or in this instance, than I thought. One of the characters in The Quiet War used a similar technique to diagnose a problem with a microalgal culture essential for the quickening of a biome. Macy Minnot applied a belt-and-braces approach I assumed would be commonplace in her present, our future: a comprehensive reading not only of the entire genome of the recalcitrant microalgal species, but also of its proteome (the complete array of structural and functional proteins in a cell). A little crude compared to the finer focus of exome sequencing, maybe, but able to capture a holistic snapshot of everything going on inside a cell, including all kinds of regulatory functions coded in non-exomic DNA. And by a funny little coincidence pinpointing a problem with another kind of transport gene, this one regulating uptake of phosphate.

'These photographs of albatross chicks were made just a few weeks ago on Midway Atoll, a tiny stretch of sand and coral near the middle of the North Pacific. The nesting babies are fed bellies-full of plastic by their parents, who soar out over the vast polluted ocean collecting what looks to them like food to bring back to their young. On this diet of human trash, every year tens of thousands of albatross chicks die on Midway from starvation, toxicity, and choking.'

There She Blows

Remember LCROSS? A rocket stage and a space probe crashing into a crater at the Moon's south pole one after the other? The huge plume that should have been visible from Earth, and should have provided evidence for or against the presence of water ice in the achingly cold permanent shadows inside the crater? I know, I know, it was a bust. No big plume, no instant results. It all happened so long ago, all of ten days, and the world has moved on.


Well, turns out there was a plume after all, created by the impact of the rocket stage. There it is, inside the circle, right on the money. An actual spaceship (kind of) impact! According to one of the scientists on the project, “Within the range of model predictions we made, the ejecta brightness appears to be at the low end of our predictions." So it wasn't visible from Earth, or the Hubble telescope, but there it is all the same, captured by the LCROSS probe as it rode in towards its own impact. LCROSS captured spectrographic data too, and so did the Lunar Reconnaissance Orbiter, which went on to map the thermal footprint of the impacts. Scientists are analysing it. Some time soon, maybe early in November, they may have some preliminary results.

And right there is one of the problems with trying to get people interested in science, in the age of One-Click shopping. News cycles grow shorter and shorter. We want our instant fix even more instantly. Superinstantly. Hyperinstantly. But actual science is slow and painstaking. It takes time, to look at the evidence. It takes more time to work out what it means. You give people two impacts on the Moon, one right after the other. I mean, really, how much more excitement can you take? But there's no big plume and no instant answer. Pundits begin to predict a moondoggle and complain that the project was overhyped and too hastily staged. And meanwhile, the truth grows stealthily and slowly towards the light. But when it emerges, especially if it's equivocal, will it be reported?

Oh, by the way, 32 new exoplanets found.
