F*ck yes! Curiosity lands on Mars!

It was spectacularly ambitious and terrifying complicated, but at 10:31pm Pacific time, the MSL rover, Curiosity, touched down softly on the surface of Mars, and sent back its first thumbnail image of the horizon through a fisheye lens.

I watched the rover’s launch in November from my bedroom and shed a private tear of pride and hope. Tonight I was at NASA Ames in California, sharing many tears of happiness and relief.  Nearly ten thousand people packed out the parade ground inside Ames, watching the two huge screens as mission control checked off each automated stage from NASA’s JPL in Pasadena.  Ripples of applause at the switching of antennae and data feeds turned to hearty cheers and then whoops and shouts of delight as entry began, the parachute was deployed, the retro-boosters set in, and finally, MSL touched down on Mars.  It’s hard to believe any image has caused such universal joy as that first 64×64 thumbnail of the Martian surface.

Over the last few weeks I had become increasingly tired of watching NASA’s cinematic ‘7 minutes of terror’ trailer, and explaining the to best of my knowledge the intricacies of the upcoming landing.  But the event tonight, experienced not only by the scientists involved, and the thousands packed into NASA centres across America, but by the whole world through unrivalled live streaming, is something that can not be easily explained or forgotten.  Watching the landing, I had chills that had nothing to do with the coolness of the night, and seeing its success, there is a warmth and elation that is nothing to do with the celebratory swigs of fizz.

We have landed toys on Mars before, small rovers the size of remote control cars, and barely better equipped.  In comparison, the behemoth we have just lowered out of the sky from a freaking jet pack, is a fully equipped geochemical and geological laboratory.  It’s the size of a small car and weighs nearly a tonne, and we’ve just airlifted it from 500,000 miles away.  It’s going to tell us more about the geological and habitable history than we’ve ever known before, and I get to work with that data to look for traces of past life. It’s going to be an unbelievably exciting couple of years.

But first, I’m just going to bask in scientific glory and pride.  Today we touched Mars with curiosity, and Curiosity survives to tell the tale.  What a fucking awesome time to be here.

A Fortnight in ‘Frisco

Well, so much for keeping a regular travel blog.  Little did I realise, but travelling half way across the world to an entirely new place, with an entirely new group of people, and entirely new kind of work, sort of knocks you backwards for a while.  It’s been a little over two weeks since I arrived in San Francisco, and I finally feel like I’ve caught up with myself.

So, a fortnight ago I set off from rainy Wales, which became rainy London, and I soaked in the padded, rolling English countryside from the train window, only too conscious that it would be the last time I’d see anything like it for the next three months.  A warm sunset with puffy clouds and contrails, like one of Marie Robinson’s paintings, was my last sight of England.

Twenty-four hours of transit was, as could be expected, near hell.  As the hours ticked by beyond our scheduled departure from Heathrow, I was conscious of my dwindling transit time in Houston, and sure enough, I have never seen an airport at quite such speed.  My impression of Houston, Texas was green – a lot more green than I had been expecting.  But no time to explore and I was straight onto my flight across the mountains to ‘Frisco.

It was dark when I arrived, but I was welcomed like a lost friend into my cosy houseshare in the centre of the City.  This Californian attitude is easy and heartfelt, and something that many places could benefit from.  Never mind the acts of blatant generosity (dinner, wine, lifts to the train station), just a smile when you arrive is enough to dispel any gloomy thoughts.

New friends in San Francisco

New friends in San Francisco. Me and my new housie Julie on my birthday.

Well, I was well looked after by my housemates, and the first weekend was spent exploring the city, getting my bearings.  I think I had been in San Francisco less than 12 hours when I saw my first naked man.  Five in fact, in the gay centre Castro, just a 15 minute walk from the house.  Just sunning themselves in the square, they brought towels to sit on, although I’m not sure whether that was for their benefit or for the benefit of succeeding patrons.

The weather has been unseasonably warm for July, I am told.  It has been mid to high 20s and clear most days in the city, although the dense marine layer of cloud blanket and fog usually rolls in around sunset, and perseveres until mid morning.  The weather here is so dramatic and dynamic, it reminds me of this heartbreakingly beautiful time lapse of clouds over the Canary Islands.  It could just as easily be here.

So once settled in San Francisco, Monday was time to start my new job. NASA here I come.  The commute was ridiculously easy, buses and trains door to door – although so few people seem to use it.  The numbers of cars are frightening.  I’m carpooling now with a postdoc in our lab, and every morning we sail down the freeway that is packed bumper to bumper with one-commuter cars.  It seems madness when the pubic transport is so efficient, but then I guess Americans sure do like their cars.  Some of them even have six wheels. Why? Beats me.

NASA Ames is a lot more homely than you might expect.  Nestled right up next to the Moffatt Airfield, the aeronautics heritage is ever-present.  The science buildings are dwarfed by vast wind tunnels and hangars, used rarely now modelling technologies are so much more efficient. I was told that the largest wind tunnel there uses as much energy as the whole of San Francisco when in operation.  Although that fact was later floored by the laser at nearby Lawrence Livermore, which in the few picoseconds of its operation uses as much energy as the whole USA.  Anyway, big machines doing big science.

The second most amazing thing about NASA is how friendly everyone is.  Must be California again.  The lab is made up of a couple of PIs, a few postdocs, and a seemingly endless stream of short term researchers, interns, and summer students.  Even those who are here short term are welcomed, inducted, and given free reign in the labs, permitting the kind of self-driven, self-motivated blue sky research that sets NASA apart from other universities and research institutions.  All specialisations are mixed in together.  I’ve had meetings with algologists, shared beers with geobiologists, visited the golf club with molecular biologists, and my office is sandwiched between the eminent Mars geologists that I spent my academic career referencing and respecting.   I feel so different to the talent base there, and yet so welcomed for the skills I do have.  It is a nurturing environment that I could easily get used to.

And so two weeks have passed already.  I’ve set up my experiments, caught up on sleep, finished all the books I brought with me, and finally unpacked my suitcase.  I’m on first name terms with the guy at the corner shop, and the guy who drives the NASA shuttle bus, and pretty much everyone in California, or so it seems.  I’m looking forward to a profitable and fun six weeks in Frisco, with a short visit to Pasadena for AbGradCon, and then an epic road trip to take in all the sights that differ so much from the English countryside I’ve left behind.  And then, who knows.  I’ve got 2 months to think about that….

 

 

Moving Out and Moving On

Not enough posts from me in the last month or so.  Well, none at all.  But I do have the best excuse of all.  Try writing a 360 page thesis, and a 600 page atlas in a month, and then see how motivated you can be to write more than an email.  Anyway, you’ll be pleased to know I survived the experience, and the thesis was gleefully, if exhaustedly, submitted on the 6th June.

Since then it has been all change at Pen and Ink towers.  After a week long conference, supposedly exploring the origins of life, but mostly exploring the local wine lists courtesy of the Lyon Institute of Origins, I packed up and drove away from Oxford for the last time, ending an eight-year era that has been the majority of my adult life.  A tear was shed, but stepping out into the unknown can be exhilarating with a look to the future instead of the past.

The last week has been a complete change to the pure academic life I’ve been leading of late, as I organised and led the Diamond Jubilee tour of The Ancient Men Morris Dancers on their 107th tour in 60 years.  This past week we have danced from Llandeilo to Llanelli, Camarthen to Cardiff, in some of the most inclement weather the UK has seen for years.  An unremittingly wet, but unremittingly fun week was spent with some of the finest people I know, and while the bruises and blisters may take some time to heal, the memories will stick around for a good while yet.  Here’s a photo of us after our last dance on the beach at Port Talbot.

The Ancient Men at Port Talbot

So, onwards and upwards to this future, and I am now counting down the days before I leave for my summer of adventure.  On Saturday, I fly out to San Francisco, to join the exalted ranks of NASA scientists as we strive for a truer understanding of our place in the universe.  Or, more simply, I’m going to poke some algae for a couple of months.  The plan is to try and approach some of the enigmas of early Earth microbial systems from a biological point of view, with a view to understanding what they may be doing, or may have done, if life arose elsewhere.  I expect the work to involve collecting, culturing, and sequencing algal mats, as well as investigating nutrient flows and responses to extreme external stimuli.  I have high hopes and am super excited for a new direction and a new location.

Also super exciting is the prospect of living and working in San Francisco.  Renowned for its microbrewery and chilled out folk culture, somehow I feel I’m going to get on pretty well there.  I’ll be living just off Alamo Square, and while its about an hour commute, I think its going to be well worth it, for living in the middle of everything.  Recommendations for places to hang out, or things not to be missed are greatly welcomed!

As seems to be the thing these days, I’m going to try and keep some semblance of a travel blog/diary right here for those of you who will be missing me desperately, or want to find out how I’m treating San Francisco.  So watch this space for considerably more updates on life as a Brit in the States, life as a Morris dancer in San Francisco, or life as a palaeontologist at NASA.

 

 

Microbes on a Moonbeam: Update from the JoC

Two weeks have passed since Richard Hoover’s paper in the Journal of Cosmology, claiming evidence for cyanobacterial fossils in meteorites, broke the news.

The feedback I have received from my report at that time has been most encouraging, and from scanning the popular press, and internet blogging community, I have been warmed by the healthy logical scepticism that dominates now.  To be honest, I thought the matter was settled, and we could all put it behind us as a lesson in overexuberant interpretation and sloppy scientific publication.

But no.  It would seem that the Journal of Cosmology are still thrashing around in a borderline hysterical way, with a tone very much like that of their soon-retracted ‘The terrorists have won’ official statement.  This time, an email sent round to the JoC mailing list, also replicated on the JoC website, seems to blame the Obama administration for slandering Hoover and the Journal of Cosmology.  Republicans, much?  And we are all made to feel like horrible bullies for making poor Richard Hoover ‘terrified’.

The email is copied below.  What strikes me most is the ‘facts’ stated by the JoC, that  ‘The IJA had received a paper by Hoover, but it was never reviewed as it was determined to be too lengthy’, and ‘NASA’s Chief Scientist … brazenly lied’, for example, while being of great import to our understanding of what is going on, actually have no corroborating statements or references to back them up.  A journal, of all places, should see the absolute necessity of that.  You could argue with every point made, but why do I get the feeling you would be beating your head against a brick wall?  Anyway. Here it is, and I’l let you make up your own minds.

Subject: Obama White House, Meteors & Microfossils–The Slander Campaign

-In 2007 NASA Approved Hoover Data For Publication: Discovery of Microfossils in Meteors
-In 2011 NASA Denounces Hoover & JOC For Publishing Data
-What Changed?
-Obama Elected President–White House Intervenes on Day 1 of Story
-NASA Threatens NASA Scientist. Orders Hoover Not to Speak to Media
-NASA Chief Scientist Lies to Media 

On March 5, 2011, the Journal of Cosmology published the data of Richard Hoover of NASA, which NASA approved for publication
in 2007: the discovery of microfossils in 3 meteors.  The Journal of Cosmology, its editorial staff, and Richard Hoover of NASA were subjected to a campaign
of slander and defamation by NASA administrators and NASA’s Chief Scientist after the Obama White House became involved.

-2007 NASA administrator Michael Griffin was ordered by White House to Lie About Climate Change.
Now they are lying about the Hoover discovery. Politics and religion have again trumped science.

The Facts

1) In 2007–NASA approved the submission of the Hoover Microfossil-Meteorite data for publication.

2) The IJA had received a paper by Hoover, but it was never reviewed as it was determined to be too lengthy.

3) Hoover wrote the paper submitted to JOC in Sept-October 2010 and submitted it in the first week of November of 2010.

4) The Hoover paper submitted to JOC, and the data it contained, had never been reviewed or rejected by any other journal, but contained the data approved by NASA in 2007 for publication.

5) The Hoover paper was reviewed, and subsequently underwent a major revision and was resubmitted in November, and again reviewed and approved. But it was not immediately published in JOC as is our normal standard procedure.

6) For the next 4 months the Hoover paper was critically examined by a Referee/Editor who went over it line by line, even enlarging the photos to pixel size to search for any evidence of tampering or fraud or anything which would make the data suspect. The data looked solid.

7) We were well aware the paper would be controversial, and were braced for slanders and defamatory attacks.

8 ) Before it was published the Hoover paper was made available to the scientific community for comment.

9) It was published in the first week of March and immediately met with an avalanche of slanderous attacks, led by a NASA administrator at Ames Research Center and a fake expert, and two media outlets with ties to NASA.

10) JOC quickly became the target of these attacks, now led by NASA’s Chief Scientist, who, to our astonishment, brazenly lied about the history of the Hoover paper and about JOC and its review policies. In so doing he maliciously disputed the legitimacy of the work of two NASA Senior Scientists Science Directorates who have published five peer reviewed articles in JOC, and over 30 NASA scientists and 4 NASA astronauts who have also published their own peer reviewed work in this same journal. JOC has in fact been guest edited by a NASA Senior Scientist Science Directorate, and another senior scientist at NASA/JPL. NASA’s chief scientist was willing to discredit anyone and everyone including top scientists at NASA, in order to destroy the legitimacy of the Hoover discovery.

11) Dr. Chandra Wickramasinghe spoke by phone with Richard Hoover the weekend the article was published, and reported that Hoover was clearly “terrified”. Hoover reported that NASA officials had been threatening him and “shouting” and “yelling and screaming” at him, demanding that he recant. They also ordered that he was not allowed to speak with the Press.

12) Over the following week we received 24 commentaries on the Hoover article. Most of these were sympathetic.

13) JOC is so confident of the data the editors at Science and Nature magazine were invited to cooperate in an independent review. These editors were uncooperative.

14) To date, there is no evidence the Hoover data is not accurate. The preponderance of evidence is these are microfossils of microorganisms which are extraterrestrial in origin and which colonized these structures and the parent bodies, before this planet was formed.

15) We had anticipated the results would be met with hoots of derision. We anticipated slander and defamation. We believed that much of this would be motivated by ignorance, fear, and religious beliefs. We did not anticipate that NASA’s Chief Scientist would lead a slander campaign and boldly make up easily disproved lies about the Hoover paper and JOC. We frankly wondered why he would maliciously defame the work of numerous NASA scientists who had published in JOC and why he did not fear consequences from officials higher up.

16) On Friday, March 18, 2011, Dr. Rudolf Schild, Editor-in-Chief of JOC spoke at length with Richard Hoover and learned that the White House, i.e. the offices of President Obama, became a party to this issue almost immediately after the story broke. The exact nature of this involvement is unknown to us.

17) We have been concerned that Richard Hoover might be forced to recant. He has not done so yet. However, it is also clear he has been under enormous pressure at NASA by powerful forces which wish him to disavow his findings.

18) The involvement of the offices of the President of the United States in this sordid affair, and with all its power, is most distressing. What the motives are, are unknown to us, though clearly the entire campaign of slander, defamation, intimidation, took place after the Obama White House became involved.

These are the facts as we know them. We believe the data is real. The implications profound.

We have to consider if a mountain-sized chunk of this planet was sheared from the surface and tossed into the abyss, only to land billions of years from now on another planet, that this chunk of expelled Earth would be peppered with the fossilized remains of various organisms. Hoover found fossils of microorganisms which had lived in the parent bodies which may have included planets older than Earth.

The Hoover data, by itself, does not mean life on Earth came from other planets. It simply means we are not alone–and the implications are staggering. However, based on the evidence compiled in an inexpensive book, “The Discovery of Alien ExtraTerrestrial life” and which includes Hoover’s discovery and landmark paper, and the discoveries of other independent scientists, the conclusions are threefold:

We are not alone. Life is everywhere. Life on Earth, came from other planets.

JOC never intended to take the safe road. Our goal is to advance science. We are open to all ideas, even those we disagree with, so long as they are backed up by science and scholarship. This is why JOC, with 15 Million Hits for March alone, has become one of the most read scientific journals in the world.

It takes courage to lead. It also takes intelligence to recognize when it is time to move on. The involvement of the offices of the president of the United States in this sordid affair, and with all its power, is most distressing. What the motives are, are unknown to us.

Our goal is to advance science.

Microbes on a Moonbeam: Disentangling the Meteorite Microbe Claims

Earlier this month, a paper was published in the open access online Journal of Cosmology, claiming to have identified verifiable alien cyanobacteria in rare water-rich meteorites.  The paper, published by Dr. Richard Hoover at the NASA Marshall Flight Centre, was immediately picked up by various news outlets and soon, news of the finding had spread across the public domain causing amazement and outrage in equal measure.

Why?  The claims are controversial enough, but increasingly, all is not as it seems with Richard Hoover, his microbes, and the Journal of Cosmology itself.  Many people have said many things in the week following the announcement, and it is my hope to consolidate some of this, and also to shed some light from a personal perspective – I have a review paper published with the Journal of Cosmology in the same issue.

So, as far as I see it, there are two main questions that should be posed of the Hoover-microbe furore:

  • Is the claim true?  It is good science?
  • Has the paper been properly peer reviewed and published?

Various pieces of evidence may be brought to bear on each of these questions, and the story may change as more facts become available, but addressing each one should help to disentangle the complex issue.

The Science

In summary, Richard Hoover claims to have found filaments of alien cyanobacteria embedded within CI1 carbonaceous meteorites.  These meteorites are exceptionally rare – only nine have ever been recovered – and have an unusual petrology and structure.  They are composed largely of clays and carbonaceous material, held together with salts such that, when the rocks are soaked in water, they disintegrate.  Hoover has taken six samples from two of these meteorites, and tested them geochemically, as well as imaging them using Environmental and Field Emission Scanning Electron Microscopy.  Great pains were taken to reduce the chances of contamination with modern material during the preparation process, and a method developed by the author previously, using comparative nitrogen contents, was used to demonstrate that the imaged structures were not modern contaminants.  Hoover compares filamentous and variously tapering and bulging structures in the rock to forms of modern cyanobacterial genera, before discussing more general implications for life existing in the solar system, and even seeding our own planet in the past.

Hoover's 'Microbial' filaments

Hoover's 'Microbial' Filements

That is what the paper says.  But to the scientist, it does seem to simultaneously say too much, and too little.  It says too much about history, general astrobiology, and meteorite petrology which should have been, or should be, covered elsewhere.  And for such a big and important claim which understandably makes good headlines, the scientific method that supports it is notably lacking in substance.  The Journal of Cosmology picked up on the grumblings of the scientific community fairly quickly, and invited 100 experts to comment on the findings of the paper.  This commentary is now published on the Journal’s website alongside the paper.  At the time of writing, 21 invited scientists have offered comments, and the views are certainly varied.  Many accept Hoover’s findings without question, and use them as a platform for further discussion as to the search for, and implications of, extraterrestrial life.  Some agree with Hoover’s findings, but have qualms with the presentation or weight of evidence for certain of his conclusions.  And some scientists, notably Michael H. Engel of the University of Oklahoma, and Martin Brasier of the University of Oxford, find much of Hoover’s evidence unsubstantiated, and interpretations reached without proper appreciation of the extraordinary evidence needed to prove his extraordinary claim.

My personal opinion is one of scepticism.  Claiming to find life in a meteorite is indeed an extraordinary claim, and given that we have not abundant evidence for life verdantly colonising other planets and bodies within our solar system, we must logically assume that it is rare.  Thus, it is more likely that such structures are abiogenic, than being formed by life.  Biogenicity may only be confirmed by multiple lines of supporting evidence, and convincing disproof of the null abiogenic hypothesis.

While Hoover’s work goes to great lengths to prove that the structures are not modern contaminants – including exhaustive isolation methods during preparation, noting the fact that the filaments are embedded in freshly fractured rock surfaces, and the fact that their elemental and protein constituents do not match with measured modern biological objects – it does fail to acknowledge the likelihood that the structures, while being native to the meteorite, are in fact abiogenic.  As any Precambrian palaeontologist will tell you, identifying cellular fossils in Earth’s rocks is fraught with difficulty.  Disentangling true body fossils from abiogenic structures like carbon chains (as in the 3.4Ga Apex Chert, proposed as biogenic by Schopf and Packer in 1987, and subsequently given an abiogenic explanation by Brasier and others in 2002), and carbonate globules (as in the Martian meteorite ALH84001, proposed as biogenic by McKay and others in 1996, and subsequently given an abiogenic explanation by Golden and others in 2001) is an essential and logical part of the scientific process necessary to confirm life in an otherwise barren rock.  The biological morphology would also need to be supported with multiple other lines of information – contextual, geochemical and elemental, and the much more likely abiogenic null hypothesis for each supposedly biological signature would need to be first disproved.   Only in light of these many lines of robust evidence, could the structures be confidently assigned a biological origin.

Martin Brasier, of the University of Oxford shows compelling images of ambient inclusion trails (included below), which are formed by the migration of a mineral crystal through a lithified substrate (Reported in detail by Wacey and others in 2008).  These purely abiogenic processes create structures that look strikingly similar to Hoover’s trichromic cyanobacterial filaments.

In a personal communication, Ian Musgrave of the School of Medical Sciences, University of Adelaide, drew my attention to magnesium sulphate nanotapes that closely resemble the tape-like structures reported by Hoover (Zhou 2006).  Further, Gounelle and Zolensky demonstrated in 2010, that magnesium sulphate bacteria-like structures do occur in CI1 meteorites due to post-landing changes in water content.

The general outcry by scientists and the informed public since publication of Hoover’s paper, not only in the official Journal of Cosmology commentary, but also on countless blogs and social media discussions bears testament to the fact that the science is not as robust as it could be.  An official statement from Dr Paul Hertz, chief scientist of NASA’s Science Mission Directorate in Washington, seems to be trying to put distance between NASA and the paper:

“NASA is a scientific and technical agency committed to a culture of openness with the media and public. While we value the free exchange of ideas, data, and information as part of scientific and technical inquiry, NASA cannot stand behind or support a scientific claim unless it has been peer-reviewed or thoroughly examined by other qualified experts. This paper was submitted in 2007 to the International Journal of Astrobiology. However, the peer review process was not completed for that submission. NASA also was unaware of the recent submission of the paper to the Journal of Cosmology or of the paper’s subsequent publication. Additional questions should be directed to the author of the paper.”

Even though Dr. Rocco Mancinelli, Editor of the Journal of Astrobiology later says that the manuscript was rejected after peer review, the whole affair remains suspicious.

But it is the job of the publication process to pick up on any problems, so now the Journal of Cosmology itself is coming under scrutiny.

The Publication

The Journal of Cosmology website, as the first encounter, does not inspire confidence.  In these days of easy website hosting, creation, and design, the unprofessional look of the page is jarring, and harks back to a MySpace age, where fourteen-year-old musical wannabes with very little design taste could make a page that looked surprisingly like this.

But look is not everything.  Giving the benefit of the doubt, and taking the Journal at its word, one can assume that its concern is more with good, peer-reviewed science, and not with superficial appearance.

Any paper published by an academic journal must first go through what is known as the ‘peer-review’ process.  An author, or group of authors submit a manuscript to a journal for consideration.  The journal first decides whether they are interested in publishing the paper, based on the topic, and then they send the manuscript out to at least two experts in that particular field – the peers.  The experts are asked to assess the paper on the basis of relevance to the field, international importance, and the robustness of the science carried out.  The peers will then either recommend the paper for publication, and advise ways in which the paper could be improved, or reject the manuscript, giving reasons.  The peers remain anonymous throughout.  After correction and redrafting of a recommended manuscript, the journal will accept it, and it will move into the ‘proof’ stage.  Here the text is typeset by sub editors of the journal, and returned to the authors for final error checking.  It is the job of the subeditors and the authors together to ensure that all typographical, grammatical and subject errors are picked up and corrected before the paper is published.  Only after this has been completed, will the paper appear on an online or in print, and may be cited by subsequent papers.  The publication process can be extremely lengthy, often taking months or even years from initial submission to publication.  It is a rigorous and thus time-consuming process to ensure that the science is as good as it could be, and potential queries and qualms are addressed premptively.

Given that the peer review process is specifically aimed at making the science in a paper as robust as possible, it is then reasonable for non-specialists to interpret the results at face value, as being the best they can be.  Disagreements with the interpretations may be subsequently made, but the assumption is that results were reached in a way that is generally accepted and respected by other experts. This should be the case for the Hoover paper in the Journal of Cosmology, just as it is the case with every paper in every academic journal.

Now, I am in a bit of a special position, in that I have a paper published in the Journal of Cosmology in the same issue.  This was an invited submission, passed on to me by my supervisor, and the paper is a broad theoretical review of the potential for life in our solar system.  It is nothing groundbreaking, but was intended as part of my PhD thesis conclusions.  The chance to publish it was an added bonus, so I submitted it on a wing and a prayer, on 1st February, for publication in the March issue.  I should add at this stage, that the Journal of Cosmology is one of many ‘open-access’ journals – requiring no payment or subscription in order to read the articles within.  It is also exclusively an online journal, so printing related publication times are unsurprisingly significantly reduced.  Still, I was somewhat surprised that they expected just a month-long turnaround from all reviewers, authors and subeditors.

Along with the manuscript, I was asked to recommend five potential experts who would be a position academically to review my work.  This is normal for academic publication – as often the authors themselves will have the best idea of who the experts are in their field.  The journal may not use these recommendations (obvious problems of the author only choosing people who will review their work favourably apply here!), but they are often used as at least a starting point.  I selected reviewers from a range of fields, from space science to microbiology.  On the 24th February, I received an email from the Journal of Cosmology, informing me that my paper had been seen by two reviewers and that they had both recommended it for publication… and this is where the process became a little irregular.  Normally, the reviewers would write a few short paragraphs confirming their thoughts on the manuscript and directly advising changes and additions.  No such comments were included in my communication with the editors.  They merely said:

“Your article has been reviewed by two referees, both of whom recommend publication without need for significant revision.

However, both felt that many of your references were outdated, and that if you included, or at least mentioned, some of the recent research and theories which have been published, RE: Europa, Titan, Enceladus, it would make for a much stronger paper.

SEE FOR EXAMPLE:

http://journalofcosmology.com/Contents5.html

This was reasonable feedback, and there were several references that I had inadvertently missed – not difficult when you are reviewing a large amount of literature.  Even so, I thought it odd at the time that no reviewers comments were included.  Nevertheless, I revised my manuscript, and resubmitted it on the 27th February.  I received an email from the Journal confirming receipt, and saying it was being ‘processed’.  I assumed that this meant it was being sent back to the reviewers for approval, but didn’t hold much hope for it being ready in time for the March issue.  It was to my great surprise, therefore, that I received an email on 1st March:

“Your revised article has been reviewed, accepted for publication, and can be viewed at this link: http://journalofcosmology.com/SearchForLife131.html Your article, with links, has also been added to the Table of Contents for volume 13.”

And so it was.  I was amazed – how efficient!  But, no proofs?  As a bit of a pedantic proof reader, I was quite looking forward to seeing proofs and being able to check my own writing for errors, and was very surprised that the Journal did not do this.  Perhaps it is because it is online, I thought, perhaps because it is open access.  I gave them the benefit of the doubt.

But when Richard Hoover’s paper in the same issue started to make a stir in the scientific community, my doubts were resurrected.  I decided to do a little prying.  So I contacted all five of my suggested reviewers to ask if they had, in fact, reviewed my paper.  To my astonishment, none of them had even seen a sniff of it.  As I said before, the recommended reviewers are not always used, but as the Journal is primarily about Cosmology, and my manuscript was mostly about astrobiology, I was more than a little surprised that none of my suggestions, even one who had previously published in the Journal of Cosmology, had been approached.

There was also a small matter of me being credited with a PhD I do not yet have.  Not something to cause complaint from someone like me, on a relatively un-ground breaking paper like mine, but still something completely unfounded.  It now appears that they have done the same with Richard Hoover.  On all NASA Marshall Flight Centre (his employer) sites he is listed as Mr, and yet, the Journal of Cosmology have given him a Dr., as they did with me.  Some critics suggest that this is Hoover himself trying to overstate his position, but I can attest that it is, in fact, coming straight from the journal.

I read the Hoover paper.  Now, I am not senior enough to offer heavy weight criticism about the scientific methods, although I do still have my opinions (expressed above).  But I am a freelance editor, and I know an edited piece of writing when I see one.  Or rather, I know a not-edited piece of writing when I see one.  In my experience and opinion, Richard Hoover’s paper is just not very well written.  In overall content, it is not the concise and exact writing that is normally used to report important paradigm-changing claims such as this (see every paper published in Science and Nature for the desirable format for ground-breaking research papers).  There is historical perspective, and direct quotes, which could be just as easily cited as references in the text.  We are told that a falling meteor broke a branch from a tree, and are quoted the philosophical musings of nineteenth century scientists for nearly six pages before the author’s contributions are even broached.  The discussion following the reported results are not relevant to the major finding of the paper, and fail to identify any of the possible alternative interpretations of the microbe structures, other than discounting the fact that they are modern contaminants.  Typographically, the manuscript is riddled with errors.  Fractured and nonsensical sentences, such as:“It should be noted that one seriously Murchison sample was found to be contaminated…” are frighteningly common.  Symbols and units are erratic too – ‘H2O’, ‘SiO2’, and ‘200oC’ are errors that I would expect to find in a an undergraduate essay.   I do not blame Richard Hoover for this.  We all make a mess of our sentences when editing, but it is the job of reviewers or proof readers to pick this sort of thing up.  Formatting is odd as well – not all figures have their own figure caption, making interpretation of the data difficult without intense reading.  This is just not what I would expect from a professionally peer reviewed and edited journal.  How did they let it slip through unless, and this is just a logical conclusion to draw from the weighty evidence in its favour, the Journal of Cosmology are not doing what they say they are?

Don’t get me wrong, I am not casting unfounded aspersions on the basis of my own biased opinion, and if the reviewers of the Hoover paper, or indeed my paper, come forward and say they did their job to their accepted standard, I will not doubt it.  If the Journal of Cosmology can stand up and say they have done all that is expected of a respected academic journal in terms of presenting good science in a good way, and provide robust evidence in support of it, then my qualms will only lie with the reviewers.  Until that time the Journal is unavoidably sitting under a black cloud of suspicion.

Clearly, the Journal is aware of the criticism coming its way – as evidenced by this official statement preceding Hoover’s paper on the website.  In itself it is not that odd, and is a natural defence against the press’ and public’s scepticism of the paper.  But when I first came across it yesterday (10th March), it read very differently, and not so objectively:

“Official Statement The Journal of Cosmology,

Have the Terrorists Won?

The Journal of Cosmology is free, online, open access. Free means = No money.

Our intention has always been to promote science and this means, particularly in this case, stepping on the toes of the “status quo” who have responded with a barrage of slanderous attacks. They are lying to you.

The Journal of Cosmology is a Prestigious Scientific Journal Two of NASA Senior Scientists Science Directorates have published in the Journal of Cosmology (JOC). A NASA Senior Scientist Science Directorate served as a “guest” Executive editor and repeatedly referred to the Journal as “prestigious.” Four astronauts, two who walked on the Moon have published with JOC. Over 30 top NASA scientists have published in JOC.

Top scientists from prestigious universities from around the world have published in the Journal of Cosmology, Harvard, Yale, Stanford, Berkeley, UCLA, Oxford, Cambridge, MIT, and so on. Sir Roger Penrose of Oxford and who shared the “Wolf Prize” in physics with Stephen Hawking is Guest editing the April edition.

Peer Review NASA Senior Scientist Science Directorate Joel Levine, while participating in a NASA press conference, remarked about how his papers were peer reviewed and he was required to revise all of them, even though he was the editor for that edition of JOC!

As every editor, and guest editor will attest, all articles are subjected to peer review. We reject over 30% of invited papers and over 70% of those which are not invited. Over 90% of all papers are sent back for revision following peer review. Every editor, and Guest editor, has had their work subjected to peer review, and every editor has been required to revise their articles after peer review. Even the executive editors have been required to revise their papers after peer review. We believe in peer review. Peer review provides wonderful feedback which can help make a paper better, or which can explain why the paper is hopeless and must be rejected. However, we do not reject great papers because we disagree with them as is the habit of other periodicals.

Richard Hoover’s paper was received in November. It was subjected to repeated reviews and underwent one significant revision.

Selling JOC The Journal of Cosmology has no income, a small staff, and is overwhelmed with submissions from scientists around the world. A decision was made in early February to stop publishing in June. A buy out offer was received in mid-February. Terms were agreed to in late February. The offer was made public in February. Hoover’s paper was received in November of 2010 and published in March.

We were well aware we would suffer profound, slanderous, attacks by those who would do anything to destroy our reputation. If Hoover’s paper were a factor in this sale, we would have never published it. They are lying to you.

Have the Terrorist Won? Only a few crackpots and charlatans have denounced the Hoover study. NASA’s chief scientist was charged with unprofessional conduct for lying publicly about the Journal of Cosmology and the Hoover paper. The same crackpots, self-promoters, liars, and failures, are quoted repeatedly in the media. However, where is the evidence the Hoover study is not accurate?

Few legitimate scientists have come forward to contest Hoover’s findings. Why is that? Because the evidence is solid.

But why have so few scientists come forward to attest to the validity? The answer is: They are afraid. They are terrified. And for good reason.

The status quo and their “hand puppets” will stop at nothing to crush debate about important scientific issues, and this includes slander, defamation, trade libel… they will ruin you. Three hundred years ago, they would burn you for questioning orthodoxy. Has anything changed?

The scientific community must march according to the tune whistled by those who control the funding. If you don’t do as you are told, if you dare to ask the wrong questions, they will destroy you.

JOC offered the scientific community a unique opportunity to debate an important paper, but for the most part they have declined.

The message is: Be afraid. Be very afraid. Or you will be destroyed.

Why is America in decline?

Maybe the terrorists have won.”


By all means attack me for being small minded, call me a crackpot and a charlatan, but to me, and to the many people who also read it during its brief period on the website, this is not reasonable scientific debate and defence, but is the stuff of hysterical conspiracy theorists.  I am not even sure what point this statement is trying to make – and the fact that the Journal have since removed it, is testament to  the fact that they themselves don’t know either.  What is going on?

Only time and further developments between NASA, Richard Hoover (who has remained surprisingly silent throughout) and the Journal of Cosmology will eventually reveal the twisted processes behind this suspicious publication.  It may be that we will never get to the bottom it.  But given that the scientific world has been shaken by the strong viewpoints in play and the many apparent inconsistencies, how have the press and the public reacted?

Sensibly, for once, it would seem!  I will put together my views on how the press has dealt with this report in a separate post.  But in summary, many of the official news and comment outlets – Yahoo news, CBSTIME, Philip Ball at Nature and many many others, carried stories that emphasised the scepticism shown by scientists about the report.  Some, most notably and disappointingly, Fox News in their initial ‘exclusive’ report, and the Guardian newspaper, show very little caution in using the story to crash the headlines (leaping head first into the churnalism snake pit), but in general, the mixed reception of the paper has been well represented.

Curiously though, in his own blog post, P. Z. Myers, a biology Professor at the University of Minnesota questions why it is almost exclusively him who is quoted as debunking the Hoover findings.  In his own words: “I know I don’t have much clout with the academic establishment, and I certainly don’t control the funding…”.  Few other expert academics have commented, or at least are being quoted as commenting, other than this very nice summary from Rosie Redfield.  While I am fully in support of the media showing a bit of hysteria mitigation, I am in agreement with Prof. Myers, and disappointed in the resourcefulness of the journalists.  But that is another story.

So, is there a conclusion?  Is there a definitive answer which can be reached?  Right now – no.  A lot of things seem fishy about Hoover’s science, and about the Journal of Cosmology, and it will take much time, official statements, and academic rebuttals before it is sorted out.  I for one, however, hope that this issue does not just fizzle into obscurity, as there are important lessons to be learnt by scientists, publishers, and the public alike, about scientific transparency and open debate.

And readers, please, if you know more, if you have heard whisperings that can shed any light on this suspicious situation, please get in touch.  I will happily post links to blogs, articles or web pages that can give insight.  Croudsourcing exposed the problems with the research, let’s see if it can provide a solution.
