Suspended Animation for Worm Embryos: Life After Frozen Death | 80beats

icyMolecular biologist Mark Roth has found a way to bring frozen worm embryos and yeast cells back from the dead: he makes them hold their breath. In a paper to appear in the July 1 issue of Molecular Biology of the Cell, Roth questions the relationship between low oxygen, low temperatures, and life after death.

Freezing almost any living thing means certain doom, but, on occasion, organisms inexplicably make it through the cold. Even some humans have come back from what seemed an icy demise, for example the Canadian toddler Erica Nordby. In 2001, Nordby’s heart stopped beating for two hours and her body temperature dropped to 61 degrees Fahrenheit before rescuers found her and brought her back to life. Apparent miracles like these inspired Roth to hunt for the biological mechanisms at work.

This study did not freeze humans. Instead, Roth looked for a common life-preserving link in two frozen organisms very different from each other. He chose the nematode embryo and the yeast cell, and found that successful resuscitation in both organisms required extreme oxygen deprivation before freezing.

Roth and colleagues found that under normal conditions, yeast and nematode embryos cannot survive extreme cold. After 24 hours of exposure to temperatures just above freezing, 99 percent of the creatures expire. In contrast, if the organisms are first deprived of oxygen and thus enter a state of anoxia-induced suspended animation, 66 percent of the yeast and 97 percent of the nematode embryos will survive the cold. Once normal growth conditions are resumed–upon rewarming and reintroduction of oxygen–the organisms will reanimate and go on to live a normal lifespan.[Science Daily]

A developing nematode embryo rapidly divides its cells. When frozen, the embryo cannot divide these cells properly–and errors mean death. Roth believes that first reducing the organism’s oxygen, pauses it (as seen in the video, below) and keeps it from carrying out its job incorrectly.

The mechanism … has to do with preventing the cascade of events that lead to biological instability and, ultimately, death…. “When an organism is suspended, its biological processes cannot do anything wrong,” Roth said. “Under conditions of extreme cold, sometimes that is the correct thing to be doing; when you can’t do it right, don’t do it at all.” [Fred Hutchinson Cancer Research Center Release]

Though this research does not explain the medical mysteries of frozen children coming back to life, Roth believes that this line of research into slowing organisms’ natural functions might eventually help preserve human organs for transplant or help in surgery.

Roth’s laboratory studies the potential clinical benefits of metabolic flexibility–from anoxia-induced reversible suspended animation to metabolic hibernation brought on by exposure to agents such as hydrogen sulfide. The ultimate goal of this work is to find ways to temporarily lower metabolism–like dialing down a dimmer switch on a lamp–as a means to “buy time” for patients in trauma situations, such as victims of heart attack or blood-loss injury, by reducing their need for oxygen until definitive medical care can be given.

Gay Men May Soon Gain the Right to Give Blood | 80beats

blooddriveBlood donation is fraught with arcane restrictions and a mess of complex requirements meant to keep the blood supply as safe as possible (I can’t give, for instance, because I lived in England in the early 1990s. Thanks a lot, mad cow scare.) But one of its most controversial—a lifetime ban on donation by men who’ve had sex with other men—may finally be coming to an end.

Massachusetts lawmakers like Senator John Kerry are pushing an overturn of the ban. The Red Cross, American Medical Association, and American Association of Blood Banks all want the lifetime ban to go away, though the Red Cross supports in its stead a single-year donation ban dating back to the last sexual encounter.

The lifetime ban was enacted in 1983 before AIDS was widely understood and has long infuriated gay rights groups since it applies to all gay men regardless of their HIV status. Heterosexuals who engage in risky behavior, like having sex with prostitutes or HIV-positive partners, are only banned from giving blood for a year [Boston Globe].

Besides the ugly unfairness of that arrangement, there’s the fact that HIV testing now allows for the detection of infection just weeks after it happens, and everybody who donates blood is screened.

Dr. Norbert Gilmore, an AIDS clinician, says the first priority for medical officials has to be keeping the trust of Americans in the blood donation system. But we can do that and still get rid of rules that reflect the AIDS panic of the 1980s and not modern scientific advances.

“With the technology we have, the risks are so small that keeping this ban in place is like permanently grounding the entire aviation system because we’re afraid that eventually we might have a single crash,” he said [BusinessWeek].

The Department of Health and Human Services is considering the change. If the agency decides to ax the lifetime ban, the change would have to be approved by the Food and Drug Administration. UCLA research (pdf) found that going to a one-year ban instead of a lifetime one would bring in 90,000 more pints of blood every year; demolishing any ban based on sexual orientation, meanwhile, could bring in 210,000.

Sneak Peek at Futurama! Plus, Our Conversation With Billy West | Discoblog

Futurama New EpisodesUgly AmericansFunny TV Comedy Blog

Robot-human intermarriage. The Harlem Globetrotters performing mathematical wizardry. Hearing, “Good news, everyone!” when bad news is on the way. It means one thing: Futurama is back.

The interstellar travels of the Planet Express crew—canceled by Fox in 2003 but kept alive by syndication, straight-to-DVD movies, and the unstoppable force of geek fandom—return with 26 fresh episodes on Comedy Central, starting with a full hour on June 24 at 10PM eastern.

Here’s our conversation with voice actor Billy West. The voice behind Philip J. Fry, Professor Farnsworth, Dr. Zoidberg, and Zapp Brannigan on Futurama (not to mention Stimpy on Ren & Stimpy and Looney Tunes characters like Bugs Bunny and Elmer Fudd in Space Jam) talks of the origin of the professor’s vocabulary, why Richard Nixon is the President of 31st century Earth, and whether it’s weird to talk to yourself so much.

(For spoilers about the new episodes, check out our interview with executive producer David X. Cohen, coming in two weeks.)

Discover Magazine: Let’s get the obvious out of the way first: During the hiatus, what was the turning point when you felt like this was really going to happen?

Billy West: Because, I think, the Futurama movies sold well, it gave them an indication of who was still out there. So as I’ve maintained all along, the super fans of this show kept it alive. It’s too good to go away. That’s my feeling.

DM: We’re big sci-fi nerds, and the show itself both parodies and pays homage to a lot of the past TV shows and movies. Were you a sci-fi person before you did Futurama?

BW: I used to try to tell my friends about some cool show I saw, and so I’d go to explain and I’d say, “Wait, let me just do it for you,” and I’d wind up doing a ream of characters in a scene. So, that’s where I think a lot of artists cut their teeth, because you didn’t have any way to instantly replay anything. It was on TV, and then it was gone. And maybe you’d see it in the re-runs, but if not, you’re out of luck, Charlie.

But, the thing about those movies: The Day the Earth Stood Still and all these things that people make fun of now were hair-raising back then. You know? To see this giant robot that was going to open up his hatch in front and disintegrate the entire planet put a lot of stuff in jeopardy. It was always the human race that was at stake with sci-fi, which is what I love. I love that much hanging in the balance. It’s a popular theme, probably more today than ever.

DM: Any other particular favorites of yours?

BW: Oh, yeah. It Conquered the World, where this craft from Venus somehow wound up in the Sierra Madre hills or wherever they filmed it. This thing that was in the spaceship hid out in a cave, and it looked like a giant cucumber or some sort of root vegetable with teeth and eyes, and it had these little vampire bats that would crawl out from underneath it and go and sting people in the neck, and they’d become his servants. Everybody wants everybody else to serve them. You will serve!

DM: Does the fact that you grew up on that stuff influence the way you do some of the characters on the show? The professor, in particular, is a classic sci-fi mad scientist.

BW: Yeah, I would say so. My whole world was a sonic one. I mean, more than watching something, I listened to it, spectrum-analyzed it in my head. I could remember what pitch they were in and what accent. Was it Midwestern or was it Mid-Atlantic or was it Southwestern or Eskimo? It just registered in my head for some reason. I can’t do anything else, but I can do that really well.

I would remember the lingo that some of these guys used, and I’ve dropped it here, there, and everywhere in the show. I think there was one sci-fi movie where the guy with all the answers—the mad scientist—ran out of answers, and somebody said something to him and he went, “Ah, fuff!” So the professor wound up saying, “Oh, fuff.” There was another instance where a lot of people in the 40’s: Instead of saying “robot” they would say, “What’s the big idea with the rob’t?” So I had Dr. Zoidberg, any time he refers to them he goes, “What’s with the rob’t? Why won’t the rob’t come home?”

It’s juicy because it’s language nobody knows, and it’s a pronunciation kind of thing that nobody remembers. I’ve had a love of language since day one, and when I listen to old radio broadcasts I listen to the stuff they used to say, the detectives, or whoever. There was a whole other bunch of descriptions for things, which would be brand new today.

Senate narrowly votes down antiscience greenhouse gas Resolution | Bad Astronomy

earthonfireA Senate vote yesterday narrowly allowed the Environmental Protection Agency to monitor and regulate greenhouse gas emissions from motor vehicles. There has been a lot of spin and furor over this vote, but in the end I think that this was heavily (though not totally) influenced by a political (and heavily partisan) denial of climate change.

Here’s the deal: The Clean Air Act allows the EPA to monitor and regulate various pollutants emitted by industries. A recent provision, Section 202(a), added six greenhouse gases to that list — specifically, carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride — and paves the way to allow the EPA to actively regulate them.

However, a Joint Resolution was submitted by Senator Lisa Murkowski (R-AK), basically disallowing that Section of the Act. In other words, this Resolution would not allow the EPA to regulate those greenhouse gas emissions.

The Resolution was voted down by a 47-53 vote. Yay! Interestingly, not one of the 53 votes against it came from a Republican. A half dozen votes supporting it did come from Democrats, however.

What do we make of this?

Those who voted for the Resolution have a list of reasons. They say this is a power grab by the EPA, trying to overreach its authority. That, however, is clearly wrong. The idea of the EPA regulating pollutants goes back to the Clean Air Act’s beginnings in 1970. Since then, when new pollutants are found, they are added to the EPA’s list. Greenhouse gases are pollutants by definition, so the claim that this is some power grab is thin indeed.

There are also claims that this will allow the EPA to impose a backdoor tax on small businesses, farms, and so on, in the form of permits. This idea has more traction. I’ll note that some of the Democrats who voted for the Resolution have made these same claims as well. I agree that there is a financial burden on small businesses, and I am loathe to see it get any worse. However, I think climate change is a bigger problem overall, and it needs to be addressed.

Also, and very importantly, it should be noted that the Supreme Court ruled that the EPA must regulate these gases. That puts both those above claims into shady territory.

Regulation is needed. It’s a good thing. Regulations make sure industry doesn’t take advantage of lax laws and lax law enforcement. One of the root causes of the current recession, and the oil spill in the Gulf, is a lack of regulations and enforcement. I’m all for allowing corporations to grow and to profit, but there has to be some oversight. While the vast majority of private businesses operate above board, it only takes a handful to truly screw things up. That’s why we have laws.

But even if the supporters of the Resolution do believe those claims are valid, I still have alarm bells ringing in my head, because for at least some of them this is really about scientific ideology.

About this Resolution, Orrin Hatch (R-UT) came out and said, "There is nowhere a scientific consensus on one of the EPA’s findings that humans are causing warming or that warming is necessarily bad for the environment or for humankind." Senator Hatch, that’s utter garbage. There is a consensus. The disagreement over this is almost entirely a manufactured controversy, artificially created and pumped up by a religiously fervent noise machine.

Not everyone on that side said this, to be fair. Moderate Olympia Snowe (R-ME) stated that she understand what the science actually says, and I’m glad — very glad! – to hear that. But people like Hatch, Inhofe, and others make me very suspicious indeed — see the Related Posts at the bottom of this post for a litany of reasons why.

Obviously, this is a complicated issue. We have the real danger of greenhouse gas emissions and the real danger opposite it of over-regulation. But time and again we have seen the far-right members of Congress stomp on science, and I’m pretty much at the "fool me twice, shame on me" stage when I hear them on these issues. And I know I agree with this sentiment:

"The Murkowski resolution gives the United States Senate a choice between real science and political science," said Sen. Richard Durbin, D-Illinois. "That’s what it comes down to."

"This discussion about global warming is now political, not scientific. And this is absurd," added Sen. Bernie Sanders, D-Vermont.

As even Senator Murkowski said, science is what it is — though reading her entire statement, I don’t think she actually puts a lot of stock in it. It is my fervent hope that someday — maybe even after the mid-term elections coming up this fall — we’ll have a Congress that truly understands that and acts on it.

When the Sun Was Young, Did It Steal Comets From Other Stars? | 80beats

Comet_Hale-BoppWhen you saw the Hale-Bopp comet, you may have seen material from a distant star passing by. In a new study, a team of astronomers argues that most of the comets that streak through our solar system were actually born in other solar systems.

Given their eccentric orbits and infrequent visits, comets seem like worthy candidates for an exotic origin. But the prevailing thinking said no, they are rather ordinary. Researchers thought most of the comets that pay us a visit initially formed from the sun’s protoplanetary disk—the same swirling mass that formed our own planet—and came to reside in the weird Oort cloud region at the periphery of our solar system. From there, the gravitational bullying of larger bodies can dislodge a few like Halley’s Comet or Hale-Bopp, which swerve into an orbit that sees them visit the inner solar system now and then.

In a study in Science this week, researchers led by Harold Levison posit a different idea: Many of the comets hanging around our solar system are stolen. It goes like this:

Like most stars, the sun may very well have been created in a tightly nestled birth cluster, a stellar nursery with tens, hundreds or possibly even thousands of stars. During millions of years of intimate infancy, the newborn stars could have exchanged vast numbers of comets from the fringes of their disks, each of them winding up with an ensemble of hand-me-downs from their stellar siblings [Scientific American].

The idea arose because the Oort cloud itself doesn’t make sense under the long-standing interpretation of comet origins.

The researchers argue that the Oort cloud’s 400 billion objects could not have all originated from within the solar system: There are about 70 times fewer objects there than needed to explain the Oort cloud’s size. Therefore, the team argued, a large portion of the material that makes up the Oort cloud had to come from somewhere else [Los Angeles Times].

Levison’s team found that this material “from somewhere else” could constitute as much as 90 percent of the Oort cloud.

Other astronomers had proposed the same idea in decades past, but lacked the computing power to model such a scenario. As computing power marches ever upward, these models of the solar system may prove more and more ideas to be possible: Just two days ago we reported on a separate team that finally had the computing power to model the formation of Saturn’s tiny moons, showing that they could have formed from the planet’s rings.

Then again, a model is just a model.

Julio Fernandez, an astronomer with the University of the Republic in Uruguay, said the study was interesting but relied on several assumptions. Among them: that the sun formed in a star cluster; that every star in such a cluster formed a planetary system with a comet swarm around it, just like ours; and that the sun was close enough to other stars in the cluster to be able to capture an entire comet cloud [Los Angeles Times].

Even the population of the cloud itself, which spurred this question of alien comets, is just an estimation. The Oort cloud is a hypothesized region that extends to the most distant extent of the sun’s gravitational influence—maybe even halfway to the nearest foreign star. Guessing how many objects reside there isn’t a shot in the dark, but it’s no exact science, either.

Crushed-Out Man Stole Sally Ride’s Flight Suit | Discoblog

sallyrideWalking by a replica of Sally Ride’s flight suit during visits to NASA and Space Center Houston, Calvin Dale Smith would snicker. Later, he told his wife that he knew the location of Ride’s original flight suit. He didn’t tell her that it was in their home, in a duct tape-wrapped suitcase.

As Wired reports, Smith allegedly got his hands on Ride’s flight suit while working as a contractor at Boeing’s Flight Group Processing Office, which maintains the suits. During his time there, he also stole a NASA Omega watch and several machined spaceship parts (including a safety tether and airlock parts).

According to court documents (pdf), Smith’s wife turned in her husband, who had previously served jail time for domestic violence, after being asked to send her estranged husband his belongings. He wanted a suitcase, “the suitcase.”

Though the first American woman in space’s blue jumpsuit is estimated to fetch $2,500 if sold to the public and $3,500 at an open auction, Smith apparently, according to a local KHOU TV news report, wanted the suit because of a “crush” on the astronaut. A rejection letter found with the suit also shows an unsuccessful attempt to sell it to the Smithsonian.

According to Wired, Smith pleaded not guilty on May 27. He has a July 12 court date and, if convicted, could serve 10 years in jail. Closing KHOU TV’s report: “If convicted, Smith’s obsession with Sally is taking him on a Ride, to Federal Prison.”

No, We’re Not There Yet! The Trouble With Hydrogen Cars | The Intersection

One of the perks of being a Hill staffer is access to cool new technologies when lobbyists visit. And so in 2006, I looped around D and 2nd in a hydrogen car. When I asked the nice man who brought the vehicle about safety and the inherent 'chicken and egg' problem (cars and fueling stations - which comes first?), he provided a clearly scripted response intended to brush off public concerns. I was sure he'd repeated it dozens of times that afternoon and--needless to say--I wasn't convinced. * * * * * * * On Monday when I announced my new position with UT's Webber Energy Group, some commentors inquired about hydrogen. In short, despite all the hype, it's unlikely to become a significant source of energy. I'll explain what makes this energy carrier appealing, followed by outlining its detractors, especially regarding use in personal vehicles. Hydrogen has superior energy density compared other fuels (a whopping 120 MJ/ kg in the liquid form). You may remember that George W. Bush often brought up the way its combustion yields water avoiding emissions. He committed over $1 billion to the development of a hydrogen car. And it's true that fuel cells can produce electricity with ...


Diving into and out of the sky | Bad Astronomy

After I posted the amazing picture of the Shuttle launch and the F-15E fighter jet last week, I got a nice email from Peter Hugosson-Miller, an avid skydiver. He and some friends went jumping over Florida one day a few years back… in fact, it was on April 24, 1990. If that date sounds familiar, then maybe the picture he sent me will jog your memory:

ShuttleJump_clean_610

In the foreground are Peter and his jump-buddies, and in the background is the Space Shuttle Discovery launching the Hubble Space Telescope into orbit!

How freaking cool is that?

The picture was taken by Van Wideman, and just slays me. I remember what I was doing on that very day — getting ready to start my PhD work using that telescope, an adventure that would last for ten years. At the time, though, it sure felt like jumping out of an airplane…

The final launch of Discovery is scheduled for September 16, 2010.

Announcing My Next Point of Inquiry Guest: Bill McKibben | The Intersection

I'm excited to announce my Point of Inquiry guest, for the program airing on Friday, June 18: Bill McKibben. He is author of many great books including, most recently, Eaarth: Making Life on a Tough New Planet--which is prompting a ton of discussion right now about the new world we're going to have to inhabit for the rest of our lives (and indeed, for many generations) because of anthropogenic climate change. Although I've failed to do so for the last two shows, I'm announcing this interview in plenty of time to take questions for McKibben from POI listeners. I will be interviewing Bill on Monday afternoon, the 14th, so that leaves three full days for thinking about questions you might like to hear him address on the air. So leave your questions for Bill McKibben below, or, head over to the Point of Inquiry forums and leave them there. Either way, I'll be reading some off on the air...


The cloudy, warming Earth | Bad Astronomy

NASA just released an interesting picture of our home planet, taken from the GOES satellite:

goes_earth_20100530

[Click to massively englobenate.]

This image is in the infrared, and maps out the heat emitted from Earth. Brighter spots are giving off more IR — like the desert region in southwest South America, and the westernmost tip of Africa peaking over on the right — and darker spots show areas where less IR is emitted.

You might think that these dark spots are cooler, but you have to be careful here. The dark areas are actually cool high clouds. But they also trap the heat of the Earth — they don’t heat up themselves, but prevent the heat below them from escaping. High clouds like this are in reality warming us up slightly, even though they themselves are cold!

Interestingly, the low clouds in the image are white, as is open ocean. That means that the Earth is good at radiating away heat from its surface whether or not low clouds are present. Low clouds let the heat right through! So the type of cloud present affects the way the Earth’s temperature is maintained.

One lesson to be learned here — and it’s a good one — is that figuring out how the planet heats up and cools off is very complicated. A corollary of this is that when someone (a politician, say, or a demagogue) starts railing about scientists who are struggling with this information, they are almost certainly oversimplifying the case. Yeah, this stuff is hard. But that’s precisely why I tend to side with the majority of scientists who devote their lives to looking at this data, and not some talking head on TV whose only job is to confuse the issue even further.

[Note: I'll have another post on this very topic coming very soon. Stay Tuned.]

It’s… It’s… A Riddle!

UPDATE:  SOLVED by Frank at 12:19 CDT

Wakey wakey!  I know you’re there, ready to play.  Get those neurons fired up – hup two three four!

Your riddle today is an event.  It’s something you know about.  We talk about it all the time.  Here are your clues:

Today’s event is not one, specific time.

This event causes a structure, which is temporary.

The first time this event was detected scientifically was in 1971, but it’s believed to be part of an 1859 event.

When this event occurs, it is magnificent.

The event causes gorgeous after-effects.

The event itself is little understood.

It is associated with speed and power.

It happens everywhere, all the time.

We love it, but it causes us problems.

Okay, that should do it.  I’m presenting an event a little differently today, but that won’t cause you any problems.  I don’t expect this riddle to be up long, but you should have some fun with it.  I’m lurking in the comments, as usual.

No spiders today, Trudy

A foxy Caturday | Bad Astronomy

It’s Caturday! Which, regular readers know, I have expanded here at the BABlog to include all creatures great and small. So check out this cutie pie:

This is a young fox that lives across the street from my in-laws’ house. We were over there the other day, and I had to leave early (to come home to write, somewhat ironically). But my wife and daughter saw a fox running around the neighborhood, and saw it go into a neighbor’s yard. There were people standing around looking, so they joined them… and what they found were a pair of young kits poking around. They obviously had a lair there.

My brother-in-law took this picture, and several others. The foxes are apparently pretty tame, but I hope people still keep their distance. Also, my B-i-L has had to deal with finding mostly-eaten corpses of various prey in his yard, too. Nice. We’re starting to get pretty good at identifying bones…


Are science journalists being overly criticised? | Not Exactly Rocket Science

Muzzled_watchdogIn the UK, there is no more famous scourge of bad science journalism than Ben Goldacre, author of the Guardian’s well-named Bad Science column. In last week’s column, Goldacre published a critique of an inaccuracy-laden piece in the Observer, penned by health correspondent Denis Campbell. This triggered a sequence of ripostes including an opinion piece from the Independent’s health editor Jeremy Laurence criticising Goldacre, a response from Goldacre criticising Laurance, and a defence of Laurance from Fiona Fox of the Science Media Centre.

I have already commented on Laurance’s frankly appalling view of what journalism is, and I will leave that aside for now. Both he and Fox essentially argue that a critical overview of science journalism is necessary but both advocate a softly-softly approach that doesn’t get under anyone’s skin too much.

Laurence said, “While raging rightly at the scientific illiteracy of the media, [Goldacre] might reflect when naming young, eager reporters starting out on their careers that most don’t enjoy, as he does, the luxury of time.” Fox chimed in with “Ben was well within his rights to do his weekly column on the weaknesses in the Observer report on Omega 3 but he would not have prompted this backlash if he had done it in a different style”, and elsewhere, “I think it’s about the tone of Ben’s particular brand of critique.”

I will summarise these arguments: we like watchdogs, but we’d prefer it if they had no bite.

Both mention the difficult, high-pressure environment of the modern newsroom, which Fox refers to as “mitigating circumstances”. I disagree but there is certainly a grain of truth here about the life of a journalist. I have argued before that critics of journalism would do well to better understand such day-to-day routines, filled as they are with deadlines, editor-wrangling, dictats about what stories to cover, and many people to interview. In Flat Earth News, Nick Davies derides the culture of intense pressure for more stories in less time with less fact-checking, while simultaneously empathising with young journalists who are ground down by it.

You can understand why people who work in that environment might get a little narked with critics, especially when certain subtleties of the profession are commonly missed (hint: the journalist didn’t write the headline). This isn’t helped by the typically ferocious nature of internet criticism. It’s easy to rain vitriol on a name on a webpage over a wrong headline or a dodgy stat, while forgetting that behind the name is a real people with a real livelihoods. So I empathise with science journalists who feel that their backs are up against the wall, or who feel that they are sometimes criticised unfairly.

But none of this means that people shouldn’t be criticised if they screw up or that during such criticisms, they should be given an easy ride.

The high-pressure nature of the job merely explains some of the mistakes that are made – they don’t excuse them. At the most basic level, as an employee of a workplace, you are contracted to do a job, with all the stress and pressure that entails. If you can’t cope with that and fulfil your obligations, then you’re in the wrong job. This is particularly important in science and health journalism, because the costs of error can be very substantial.

Then there’s the old canard that the critics have it easy. Laurance accuses Goldacre of having “the luxury of time” while Fox contrasts the day of a “jobbing journalist” to the “luxury of a columnist like Ben who gets to lay bare the flaws in those stories once a week”. That’s absolute rubbish. I can’t speak for Ben but it’s worth noting that his column is written on top of his activities as a full-time doctor. I can, however, speak for myself. In the upcoming week, I will be writing 6 lengthy news pieces for this blog and a 1,500-word feature for the Times, outside of my day job in my spare time. In fact, writing this piece is eating into that time. The critic’s schedule is no less hectic and indeed part of the reason that bad science journalism is such an irritation is that correcting it soaks up time!

During my day job, I have to answer enquiries from people who have been misled by an inaccurate headline. I respond to sensationalist coverage and provide a more measured take on things. I also provide some of the quotes that work into those news pieces, often dropping all my other work to meet a reporter’s deadline – furiously reading the relevant paper (if it’s provided, otherwise, hunting it), second-guessing the angle of the story, drafting a response, and getting it signed off. That high-pressure news environment turns my office into a high-pressure working environment.

And really, regardless of how intense the schedule of a journalist is, that defence really starts falling apart when you consider that many people cope with it admirably. You’ll note that some reporters hardly ever seem to draw the wrath of critical bloggers. Why? Is it because they’re part of some secret club? Do they know where the off switch is? No – it’s because they’re simply better at what they do. They’re more careful. They do their homework. They check their facts. And most importantly of all (because we’re all human) if they do make mistakes, they take it on the chin and engage with their critics (check out that last link for my own personal fiasco and its swift resolution).

Earlier yesterday, Petra Boynton asked for resources to help journalists avoid making common mistakes and I answered that the only things people really need are humility, a willingness to learn, and time. We’ve talked about time already; the other two are just as important because they ensure that if you make mistakes, you’ll make them only once, and that you maintain accountability and professionalism.

It’s the lack of such accountability that fuels much of the frustration with bad science journalism. In fact, those who repeatedly do the worst job have a habit of not holding themselves to account. Goldacre’s attempts to track the source of the article that started all of this were protracted and difficult. The article in question has since disappeared from the Guardian website with no correction or explanation, even though the Code of Conduct from the National Union of Journalists calls for journalists to do “her/his utmost to correct harmful inaccuracies”. Instead, we get one piece in another national newspaper and one blog post criticising Goldacre for his tone.

This is not the type of reaction that instils confidence in a softly-softly approach.

The bottom line is that if people like Laurance and Fox feel that the “self-appointed critics” of science journalism are being too harsh, there must be some evidence that a more cordial tone would actually yield dividends (after all, scientists like evidence). To my knowledge, those data are sorely lacking.

Of course, most of this piece has been focused on bad science journalism and we must be careful to avoid confirmation bias. As I’ve argued repeatedly, there is plenty of good science journalism out there that often gets lost amid the venom triggered by the worst exemplars. I’m currently judging the ABSW Science Writer Awards and it’s a joy; there is no shortage of truly excellent science journalism of the sort that takes specialist skills (and a lot of time) to go out and find.

The critic who thinks that all journalists are rubbish is a straw man, but we could certainly do more to collectively highlight good science journalism (in this, I actually agree with Fox). It would serve to show the world what the craft actually looks like when done well, and it would hopefully encourage the best practitioners, who might otherwise think that their entire profession is being condemned despite their high-quality efforts. This will contribute towards raising overall standards just as much as debunking the worst articles. Social media is excellent for this and there is clearly a culture developing on Twitter where science journalists who do excellent work get praised for it. That can only be encouraged.

But in the meantime, the watchdogs are still needed. Their bites and barks may be unpleasant, but so are the consequences of the errors that draw their attention. In the end, the best way to avoid such criticisms is to give people as little as possible to criticise.

UPDATE: Martin Robbins at the Lay Scientist has an angrier take ;-)

I’ve seen many shuttle landings and the coverage always ends and the scene is a bunch of support trucks and people running around.

NASA put out a video showing some of what goes on after the camera’s go away.

Thank you NASA!

BTW: This is not the post I intended;  there is a “soon to be visible comet” out there and I didn’t have a chance to nail down a few things.  I will put out better finders charts and times but if you just can’t wait, and I couldn’t check Seiichi Yoshida’s site (probably the best comet site out there IMHO).  I think it’s a mag 5.5 right now so you will need binoculars to see it.
