“Doctor” Oz Fails at Medicine AND Physics as He Pushes Cell Phone Fear-Mongering

Posted by mattusmaximus on December 18, 2013

This recent silliness by “Doctor” Oz came to my attention: apparently, during a recent show he took seriously the notion that women shouldn’t carry cell phones in their bras because it could give them breast cancer.  My skeptical colleague Dr. David Gorski at Science-Based Medicine summarizes Oz’s idiocy and fear-mongering here…

… The story aired on December 6 and was entitled Why You Should Keep Your Cell Phone Out of Your Bra. The entire segment, lasting ten minutes or so, is one blatant piece of fear mongering. Even by the usual low standards of a typical Dr. Oz segment, this one was bad. How bad? I’ll give you a taste. Let me start just by asking what you might expect in a segment claiming a link between an environmental exposure of some sort and a specific cancer? You’d expect some actual scientific evidence, wouldn’t you? Some epidemiology, perhaps, showing that women who hold their cell phones in their bras have a higher risk of breast cancer, perhaps with some relative risks that were at least statistically significant. You might expect some scientific evidence suggesting why the proposed mechanism is plausible. You might even expect that there would be convincing (or at least suggestive) evidence that women who put their cell phones in their bras, when they develop breast cancer, develop it more frequently on the side where they stick their cell phone. These would be reasonable things to expect that, even though they wouldn’t be convincing proof, would at least raise concerns.

There was none of that at all. Zero. Nada. Zip. In fact, I was shocked at how evidence-free this whole segment was. Usually Oz at least tries to slather a patina of scientific evidence on his pseudoscience. OK, maybe not usually, but he does at least sometimes try when he’s not doing a story on alternative medicine, “complementary and alternative medicine,” or “integrative medicine,” anyway. Not here. It’s as if Dr. Oz’s producers weren’t even trying for this one. …

If you want a good analysis that thrashes the hell out of Oz’s claims from a medical perspective, definitely read through all of Dr. Gorski’s blog post.  Seeing as how I’m not a medical doctor, I won’t rehash his analysis here; but I am a physics professor, so what I can do is go through the basic physics of why it is implausible that cell phones are even physically capable of causing cancer.  In fact, I’ve written numerous posts on this topic already…

Electromagnetic Fields & Cancer Myths

This first post is probably the most thorough on the fundamental physics of how electromagnetic radiation/waves (also known as light) are generated and propagate; also included is a basic primer on the different kinds of EM waves, the EM spectrum, what role frequency and energy of light play in these issues, and the all important difference between ionizing and non-ionizing radiation.  Here’s the upshot: cell phones emit non-ionizing (i.e. non-cancer causing) radiation.

Maine Legislator Pushes Cell Phone-Cancer Woo

This article about a hysterical politician in Maine points out the implications of allowing basic scientific literacy to be trumped by the kind of psuedoscience and fear-mongering propagated by “Doctor” Oz and his ilk.

Cell Phones STILL Don’t Cause Cancer

Just a more up-to-date article outlining some more research from the Institute of Cancer Epidemiology in Denmark after it looked at more than 350,000 people with mobile phones over an 18-year period.  Conclusion: even while looking for supposed long-term negative effects, none were found.

Loch Ness Monster Activity is Likely Just Seismic in Nature

Posted by mattusmaximus on July 8, 2013

I ran across two articles recently about the latest research regarding the Loch Ness Monster.  And by “research” I really do mean serious scientific work: it seems that many supposed Nessie sightings over the years have been accompanied by audible rumbling and gas bubbling up to the surface of Loch Ness.  There seems to be a plausible geological (note: “geological” does NOT equate to “big freaking monster”, just to clarify) explanation for these phenomena.

As a lesson in critical thinking (or a lack thereof) in the media, let us compare the coverage of this research from two different sources, the Scientific American blog and the Huffington Post.  First, the SciAm blog…

The Earth-shattering Loch Ness Monster that wasn’t

Summer is traditionally Silly Season, when newspapers publish strange stories about aliens and monsters again and again to bridge holiday time – and so will July on “History of Geology” be dedicated to frivolous science stories…

In 2001 the Italian geologist Luigi Piccardi presented during the Earth Systems Processes meeting in Edinburgh a hypothesis explaining the supposed appearance of the sea/lake monster “Nessie” as a result of geologic forces.

According to Piccardi’s idea the historic description of the monster – appearing on the surface with great (earth)shakes and rumours – could be associated with bubbles emanating from the bottom of the Scottish lake of Loch Ness in response of seismic activity along the Great Glen fault system, passing below the lake. …

VERNE_1864_Voyage_au_centre_terre_Plesiosaurus

… Not only biological constrains, also the geology don’t seems to support the existence of an earthshaking monster in Loch Ness.  Common earthquakes from the Loch Ness area range between magnitude 3 to 4, larger events were recorded only in 1816, 1888, 1890 and 1901. These earthquakes don’t coincide with the years of supposed increased activity of Nessie (like 1933). Even the largest Scottish earthquakes were anyway too weak to cause any observable effects on the surface of Loch Ness (curiously the great earthquake of Lisbon in 1755 generated waves on Loch Ness, but no Nessie sighting is reported for this year).

Piccardi himself sees the value of his hypothesis more in the possibility to make geologists aware of the geological origins of some myths, as to propose verifiable cryptozoology.

Well, that seems pretty good: a well thought-out article regarding an area of actual scientific research, even going so far as to note the limitations of Piccardi’s hypothesis.

Now, let’s see what the HuffPo has to say…

Loch Ness Monster Mystery Solved? ‘Nessie’ Just Bubbles From Seismic Activity, Geologist Says (VIDEO)

… The first claimed sighting of “Nessie” occurred in the sixth century, according to Scientific American. Legend has it that the creature appears along with earth tremors and bubbling from the bottom of Loch Ness, one of Britain’s largest freshwater lakes.

Formed as a result of a long-ago collision between the northern tip of Scotland and the rest of Britain, the loch sits over the 62-mile Great Glen fault line. Piccardi argues that this position may have fueled centuries of Loch Ness Monster rumors.

“Loch Ness is exactly on the fault zone,” Piccardi said in 2001, according to The Telegraph. “When there are small shocks, it can create a commotion on the water surface. Along the fault there can be gas emissions, which can create large bubbles on the surface. There are many surface effects which can be linked to the activity of the fault.”

But Piccardi’s theory is not without critics, especially among Loch Ness Monster enthusiasts like Gary Campbell, president of the Loch Ness Monster Fan Club in Inverness, Scotland.

“Most of the sightings involve foreign objects coming out of the water. There’s two most common — one’s a hump, and the other is a head and neck,” Campbell told ABC News. “At the end of the day, there’s still sightings that are inexplicable. There’s something physical in there.” …

*facepalm*

Where to begin?  First of all, the fact that the HuffPo elevates a pseudoscientific hack – in this case, the Gary Campbell who runs a fan club for the Loch Ness Monster – to the level of a serious critic of a pretty plausible area of scientific research speaks volumes.  Apparently, to the HuffPo, “scientist” equates with “anyone who can make sh*t up”.

Next, pay attention to Campbell’s response: “At the end of the day, there’s still sightings that are inexplicable…” So that proves… what exactly?  That there isn’t a full explanation?  And how exactly does a lack of an explanation provide any validity to the explanation via invoking Nessie?  This is a classic argument from ignorance, and one could just as easily invoke leprechauns or unicorns as an explanation using such shoddy logic.

Last, but not least, is the final few seconds of the video at the HuffPo link, wherein the host shows some TV anchors moaning about how they don’t want to accept the geological research of Piccardi because they like the idea of Nessie.  The HuffPo host summed it up as follows:

“Sometimes you just don’t want scientific reasoning, and you just want to believe.”

CNN Taken to Task Over Its NON-Critical Thinking on the Boston Bombing

Posted by mattusmaximus on April 19, 2013

As I mentioned in my last post regarding this past Monday’s Boston Marathon bombing, there has been a huge amount of rumor, misinformation, and innuendo floating all over the place, and we should do what we can to combat it.

Of course, one would hope that our media outlets, such as “The Most Trusted Name in News” CNN, would take such a task to heart, making certain to get their facts straight before they report the news.  But, sadly, in the era of the 24-hour “news” cycle, it appears that getting it right takes a back seat to getting it first.

I can think of no other way to illustrate this point more clearly than to reference The Daily Show’s incredible smackdown of just how badly CNN botched some major news regarding the bombing:

CNN-The Human Centipede of News

Yup, that’s CNN… the most busted name in news.

A Brief History of The “History” Channel

Posted by mattusmaximus on April 3, 2012

I have long lamented the slow, downward spiral into an abyss of stupidity taken by networks such as The “History” Channel in recent years.  It started when a student of mine expressed his shock at seeing a show about “ancient aliens” building the pyramids on THC; fortunately my student knew it was a steaming pile of woo.  As a way of giving you some idea of how THC has gone all the way down the rabbit hole of pseudoscience and complete nonsense in its quest for ratings, I would like to pass along to you this humorous graphic I stole from my skeptical colleague Kylie Sturgess.  It sums the whole thing up nicely… :)

Resolve to Fight Deadly Anti-Vaccine Propaganda: Start with the NVIC’s New Years Ad

Posted by mattusmaximus on December 28, 2011

Just yesterday I learned that the National Vaccine Information Center, a deceptive title for one of the worst anti-vaccine propaganda groups out there, has a new ad playing in New York City’s Times Square.  Worse yet, this ad is going to be playing on the megatron screen there during the New Year’s Eve celebration on Dec. 31st!  Folks, this is bad, not just because of the content of the ad, which plays on the “pro-choice” mentality that parents are better equipped to make medical decisions than doctors and also directs viewers to the NVIC’s website, but because of the timing: due to the fact that millions (perhaps even billions) of people watch the Times Square festivities on television, this ad could easily get worldwide exposure.

The NVIC and other anti-vax groups would rather this kid get whooping cough or another deadly disease than take a life-saving vaccine.

We need to fight back, and we’ve already started.  Elyse Anders has already written a post at Skepchick on this, and I’ve also blown the whistle via the JREF Swift blog.  But more needs to be done, so here’s what you can do:

1. Direct people to reliable and trustworthy outlets for vaccine information – a quick and handy one is the Women Thinking Free Foundation’s Hug Me I’m Vaccinated FAQ.

2. Sign the new petition demanding that ABC Full Circle pull the NVIC Times Square ad.

3. Join our Twitter campaign: Tweet @DisneyChannelPR using #ABCsSickNYE. You can copy/paste one of these or write your own:

I resolve to end deadly anti-vaccine propaganda. @DisneyChannelPR Pull NVIC’s anti-vax Times Square ad http://wp.me/pbblq-6RR  #ABCsSickNYE

Whooping cough is on the rise thanks to things like NVIC advertising on @DisneyChannelPR screens in NYC. #ABCsSickNYE http://bit.ly/rXLHOd

4. Go to the NVIC YouTube video link and “dislike” the video.

5. Share this information on Facebook and other social media outlets.

6. Contact Gerald Griffin at ABC Full Circle by emailing Gerald.T.Griffin@abc.com or calling 212.456.7389 to voice your displeasure with them playing the NVIC ad.

And this campaign needs to be mounted from the inside as well as the outside: it seems we in the skeptical and pro-science community need media connections within the companies which rent out space for these high-profile ads.  We need to inform and educate these companies about the part they are playing in spreading this dangerous anti-vaccination misinformation, and we need to raise such a fuss that they’ll simply refuse the NVIC the next time they come wanting to rent the space.

Of course, none of this will work without you, because we are going up against an organization that has literally hundreds of thousands of dollars to spend on anti-vaccine propaganda.  So please take some time to get involved and take action now – it really is a matter of life or death.

Update on the Delta Airlines Anti-Vaccine Ad

Posted by mattusmaximus on November 19, 2011

In a recent blog post – Deceptive Anti-Vaccination Ad by the NVIC on Delta Airlines – I mentioned an online petition at Change.org that is gathering signatures to convince Delta Airlines to pull the deceptive anti-vaccine ad being run on some of their flights.  I wanted to pass along to you a recent update I received about this situation from my friend and skeptical colleague, Elyse Anders:

Update about ‘Tell Delta to Stop Putting their Passengers’ Health at Risk’ on Change.org

Hi,

Thank you so much for signing the petition, “Tell Delta to Stop Putting Passengers’ Health At Risk.” Delta has already committed to make some big changes: they are instituting a new review policies for future ads and will be showing a pro-vaccine Public Service Announcement beginning in December.

But we think they can do better. Do you think Delta should pull their anti-vaccine ad immediately? If so, here’s how you can help keep on the pressure:

1) Share the petition with your friends. Here’s the link to share on your Facebook wall – http://www.change.org/petitions/tell-delta-to-stop-putting-their-passengers-health-at-risk

2) Are you on Twitter? Delta sure is. They invest a lot of resources to customer service on Twitter, and this is a great way to get Delta’s attention. Here are some ideas for tweets. Feel free to write your own, just be sure to mention #fludelta and @delta or @deltaassist:

#FluDelta @DeltaAssist @Delta Thank you for changing your review process. Please, stop airing the anti-vaccine ad now! http://chn.ge/vbtnDt

When you fly, you shouldn’t have to worry about the flu. Tell @Delta to drop the anti-flu #vaccination in-flight ad now. #FluDelta

Thanks so much for supporting this important campaign,

Elyse Anders (@dELYSEious)

Another Crappy “Lake Monster” Sighting in Canada?

Posted by mattusmaximus on November 11, 2011

Here’s a new one for the “you’ve-got-to-be-kidding-me” files: a halfway serious ABC News report on a really bad video shot by someone who claims to have evidence of a lake monster in Canada called Ogopogo (basically, the Canadian equivalent of the Loch Ness Monster).  Below is the video footage in question…

Oooh, scary!!!

That’s it?!!  That’s all there is to this supposedly astonishing story sweeping the world?  Some ripples/waves in the water which are likely caused by debris?

Sometimes I weep for humanity; if this is the best that cryptozoologists can come up with (and it pretty much is the best they can come up with), then it is no wonder they are mocked.  I think the following comment on the ABC News story sums it up best…

How come most quickly taken video’s are crystal clear but any UFO – Yeti – Nessie videos look like they were shot by a 2 yr. old with a Fisher Price camera???

‘Nuff said, folks.

Deceptive Anti-Vaccination Ad by the NVIC on Delta Airlines

Posted by mattusmaximus on November 5, 2011

It’s like playing a game of Whack-A-Mole sometimes… the anti-vaccine movement is back at it again, this time with a deceptive ad on Delta Airlines flights by the National Vaccine Information Center directing people to their website for “accurate information” on the influenza vaccine.  The NVIC is the same outfit which ran another anti-vaccine ad in New York’s Times Square earlier this year.

Here’s the NVIC’s advertisement:

For the most part, it seems pretty much okay, until you hit the 1:56 mark in the video and they start discussing the influenza vaccine.  At that point, they flash a couple of shots of the NVIC website…

And here is where the real problem lies: the fact that the NVIC wants to use this seemingly innocuous ad to direct people to their website (which they would like people to think is a valid clearinghouse on vaccines) which contains all manner of dangerous nonsense and pseudoscience regarding vaccination.  I think my skeptical colleague, Elyse Anders of Skepchick, says it very well…

And let’s not forget that NVIC’s ultimate goal here is not to get people to opt out of just the flu shot. The ultimate goal of this ad is to get people to visit the NVIC website, trick them into thinking they’re looking at a legitimate government website, and get them to stop vaccinating altogether. And then put those people on planes. Which is how many vaccine-preventable outbreaks happen in the US.

The bad news is that these anti-vax loons have gotten their sneaky ad onto Delta Airlines; the good news is that the skeptical community is all over it, and a hard response is swinging into action.  Here are some things you can do to help (stolen from Elyse Anders’s post on Skepchick, btw)…

  1. Sign this petition from Change.org demanding the Delta Airlines yank the NVIC ad

  2. Tweet: “#fludelta @DeltaAssist @Delta If you’re so concerned about safety, stop running potentially deadly anti-vaccine ads http://wp.me/pbblq-6qu
  3. Comment on the video on Facebook (this video has since been removed, probably due to too many negative comments :) )
  4. Share this post on Facebook and Twitter.
  5. Encourage your friends to join this campaign.
  6. Tell Delta that it’s irresponsible to encourage anti vaccination rhetoric (you can also tell In-Flight Media the same thing).  Let them know that you are not willing to support their decision to risk your health for advertising dollars. Ask them if they’re willing to add to the anti-vax body count.
  7. Last, but definitely not least, if you communicate with the people at Delta Airlines, tell them that you will take your business elsewhere, like to airlines that communicate responsible information regarding vaccines (because money talks and bullshit walks).  For more information on this, take a look at this PSA by Every Child By Two, a pro-vaccine group, which is running on US Airways and American Airlines through the month of November:

WTFF’s “Hug Me, I’m Vaccinated!” Campaign Gets a Shout Out from… the Huffington Post?

Posted by mattusmaximus on October 31, 2011

Wow.  I’m pretty stunned by this development.  Many of you know that in the past I have been highly critical of the Huffington Post (a.k.a. the HuffPo) for their tacit acceptance and promotion of various kinds of medically-related nonsense, especially the fact they provide a big platform for anti-vaccination kooks.

However, in an interesting twist, one of their prominent writers – science correspondent Cara Santa Maria – has written a very solid and in-your-face pro-vaccine article.  Not only that, but she also gives a big shout out to the WTFF’s Hug Me, I’m Vaccinated campaign! :D

Perhaps there’s hope yet for the HuffPo…

Talk Nerdy to Me: Hug Me! I’m Vaccinated

Yesterday I got a flu vaccine at work. The coughs and sneezes are beginning to sound like bad muzak around the office, so I figured it was time to give flu season the finger. I’ve actually never had a flu vaccine before. It just never occurred to me to do so. But now that I work in a corporate office environment, the handwashing signs over the bathroom sink and little pumps of antibacterial hand sanitizer glistening on individual desks are beginning to make sense to me. I don’t want these people making me sick. I don’t want to make them sick either. I like my coworkers a lot, but I wish we lived in a country that understood the value of a sturdy facemask. I live in Hollywood, a city so image-obsessed that the only time you see somebody wearing one of those is if they’ve just gotten their nose done.

But I digress. I noticed when I proudly bore the sticker proclaiming to the office masses today that I got my vaccination, a lot of people responded that they “don’t do that” or they “don’t believe in it.” That struck me as funny. It made me wonder why, if a free flu vaccination is offered to you only steps from your desk, you would opt not to partake. …

… The truth is, even though a new meta-analysis published in The Lancet only two days ago showed an overall efficacy for influenza vaccination hovering around 59% (in adults age 18-65, spread over the last 44 years), I’ll take 59% over 0% any day. And not getting a vaccine is 0% effective against the spread of influenza. By the way, if you are one of those people who opt out of prophylaxis, please do your part by washing your damn hands. And sneeze into your sleeve, not all over your disease-laden paws. Of course, I’m now a lot less worried about your germs making me sick. So, hug me! I’m vaccinated.

More Media Fail and Silliness: Lunar Effect Babies

Posted by mattusmaximus on August 17, 2011

This week there’s been a story going around the media about a supposedly huge jump in births in a Sacramento hospital where “45 babies were delivered in 48 hours.”  Now that may or may not sound very unusual (it ends up it isn’t that strange – read on), but the really weird aspect of this is the claim made by the hospital officials with nary a skeptical thought:

“The human body is 80 percent water, after all. And, given that both menstruation and ovulation roughly follow a lunar cycle – occurring on a monthly basis – it doesn’t seem too far off to think that the moon could have a say in childbirth as well,” hospital officials said.

And, of course, the supposed mechanism for this “lunar effect”, as espoused by the hospital spokesman, is gravitational in nature:
According to the news release, the moon’s gravitational pull “can control a woman’s body” the same way the moon’s gravity controls tides.
*Cue spooky music…
Image courtesy of Nineplanets.org

First of all, the fact that 45 babies were born in 48 hours is not that significant.  Note the article states that there have been a total of 325,000 babies delivered at the hospital since 1937.  If you do the math, then this comes out to an average of about 12 babies per day – compared to the claim in the article (which basically averages out to about 22 or 23 babies in one day), this seems not very extraordinary because it shows that there was a weekend where the hospital had only double the average number of births!  100 times the average number of births would be statistically significant, but not 2 times the average.

Then there’s the stupid claim about the “lunar effect”.  Not only is this a bogus claim – click here to see why not – but it is also implausible from the standpoint of basic physics.  The hospital spokesman makes a common claim about the “lunar effect” being gravitational in nature, like the tidal effects on the Earth’s oceans.  However, if one takes a moment to work through the mathematics, this arguments falls apart pretty quickly.  For example, I perform the calculations for the tidal effects of the moon (whether it is full or not is irrelevant) on a person in my physics classes, and it ends up the tidal forces that act upon a person are stupendously small – about one-billionth the weight of a paperclip!  So whether or not you decide to wear a hat or use hair gel on any given day has more gravitational influence on you than does the tides from the moon!

That’s because the strength of the tidal forces that act on an object are proportional to the size of that object.  In the case of a large planet, like the Earth, the relative difference between gravity from one side of the planet to the other (this difference is the tide itself) is pretty big since the Earth is big.  But humans are so small on this size scale that the difference in gravity (tide) on us is miniscule.

So the next time you gaze upwards and see the full moon, appreciate it for all its beauty and wonder.  But don’t worry about it making you crazy; the failure of the media to accurately report science is a bigger threat of making you nuts ;)
