I haven’t had the chance to write much here about vaccines recently, so I was delighted to participate in MHA@GW’s initiative to highlight vaccination for National Immunization Awareness Month with a series of posts from guest bloggers entitled “Why Immunize?” My post focused on science literacy, and how to communicate with others about this issue:
In all likelihood, parents have already made up their mind as to whether or not they’ll vaccinate themselves and their children. And in all likelihood, that decision was to vaccinate.
These parents are motivated by a shared concern for their children and community. They know that vaccines prevent many childhood diseases, and that by maintaining high vaccination rates in their community, they maintain herd immunity. Perhaps they’ve seen the comparison of morbidity rates in the pre- and post-vaccine era and understand the significant impact vaccines have made in preventing the worst childhood diseases. They may have been worried about the outbreak of measles among families who took their children to Disneyland earlier this year, which hit unvaccinated people the hardest . Regardless of how they came to this decision, the vast majority of parents understand that the risks of vaccines are low relative to their tremendous benefits.
This is good news for the health of our communities. It’s critical that we continue to talk about immunization, because vaccine opponents are relentless — see the comments on my piece here for many examples of the bad science and provocative rhetoric they employ.
Speaking up is the most important step, letting parents know that their decision to vaccinate is the safest and most common way people protect their children. The anti-vaccine minority is disproportionately loud, partly because vaccines are so safe, effective and ubiquitous that they become part of the background landscape of parenting. Fortunately, in reaction to harmful pseudoscientific scaremongering and events like the Disneyland outbreak, people are motivated to speak out in favor of vaccines.
But I was dismayed to see that just hours after my piece was posted, a mainstream news site posted an article purporting to give balanced coverage on “the vaccine debate”, but instead propagated the same old mistruths and pseudoscience that have been thoroughly debunked by the scientific community again and again. This article, which features comments from a “Montana mother” given the same weight as those from a trained physician, and concludes by telling parents how to get vaccine exemptions for their children before school starts, is utterly reprehensible journalism. It’s a depressing reminder that we can’t ever let up on our efforts to educate journalists, as well as the general public, on basic scientific and medical issues
So in honor of National Immunization Awareness Month, I’m asking all of you to make a small but meaningful contribution to this effort. Please share at least one example of good news coverage on vaccines with your online and in-person friends. Your voice makes a difference in this conversation.
I was delighted to read at Jason Colavito’s excellent blog that the journal American Antiquity has just published a special section in its current issue that’s devoted to debunking popular pseudo-archaeological ideas. This is a fantastic example of the kind of outreach that I (and many others) would like to see academics and academic institutions engage in. I want to commend American Antiquity (and its parent organization, the Society for American Archaeology) for this. But with a caveat: outreach actually needs to, well, reach its intended audience. Right now, that’s not the case. Continue reading →
A little over a year ago the complete genome sequence of a Clovis individual, the 12,500 Anzick child, was published. His sequence gave us a fascinating glimpse of ancient Native American genetic diversity, and new insights into the early peopling of the Americas. At the time, however, I was unhappy about how the media covered it:
“Unfortunately, several press reports chose to find controversy in a decidedly non-controversial story by giving undue weight to problematic “alternative” explanations of Native American origins, including the Solutrean hypothesis, and other “European contributions” to Native American ancestry.”
Last week saw the announcement (also from Eske Willerslev’s lab group: they’re amazingly prolific) of the sequencing of yet another significant ancient American genome: the 8,500 year old skeleton from Washington popularly called “Kennewick Man.” This time the press did an exemplary job of covering the news.
I’ve had the Apple Watch for a few weeks now, and enough people have asked me about what I think of it that I thought it was worth writing a post. Since the majority of reviews I’ve seen are all from tech or fashion people, and I don’t find these particularly helpful, I thought I’d give a bit of a different perspective– one from a completely normal person who just happens to have gotten one early. I have the Sport version with the 38mm case, and the white band.
Let’s be real: I wouldn’t have bought this watch for myself. Despite the fabulous sums of shill money that certain antivaxxers are convinced I’m pulling in, I actually don’t have a spare $350 lying around. (If for some reason you’re burning with curiosity about what I make, go look up NSF biology postdoc salaries for a ballpark figure). The watch was an early wedding gift from my fiancé, who is both in love with being an early adapter of new tech but a staunch enemy of all things Apple. Yeah, I don’t get it either.
But that being said, I absolutely love my watch. I’ve never worn one regularly before, but three weeks of wearing this one has made me an addict. Here are the ways in which I use it, and the ways in which I don’t. Continue reading →
My colleagues and I have just published a paper on the genetic diversity and population history of contemporary Iñupiat peoples (the indigenous inhabitants of the North Slope of Alaska) in the American Journal of Physical Anthropology. It’s open-access for at least a few months, so you can read it in its entirety here, our collaborator Dr. Anne Jensen ‘s thoughts on it here, and Archaeology Magazine’s article on the paper here. I’ve also summarized our findings below.
The pseudoscience community has long tried to convince parents that the MMR vaccine (to prevent infection with the diseases measles, mumps, and rubella) causes autism, despite study after study after study after study after study after study after study after study* showing that there is no connection between MMR and autism.
The pseudoscience community’s desperate investment in this myth–and the shaky ground they stand on– is illustrated by how quickly they shift their stories:
“Thimerosol or aluminum, or some kind of ‘toxin’ is the cause!”Debunked .
“No, I mean, it’s just too many too soon!”Debunked
“No, but seriously, natural infection is way better because unvaccinated children are healthier than vaccinated children!”Debunked.
And just yesterday, another study (Jain et al. 2015 Autism occurrence by MMR vaccination status among US children with older siblings with and without autism) has come out debunking yet another antivaccine myth: that the MMR vaccine somehow “triggers” autism in children who are genetically susceptible to it.
My not-so-secret goal with this blog is to improve public science literacy and to help people become more critical consumers of information. As a consumer activist and critic with enormous influence, one might hope that Food Babe’s goals are similar to mine. But I’m afraid I have to give her methods a big red F, and for distressing reasons. Before I get into that, however, I want to give readers who aren’t familiar with Food Babe some background.
Like the decision to vaccinate, the choices we make about food have significant consequences to our health. It’s easy to find advice on how to structure our diet–there is an overwhelming volume of admonitions to eat more protein!, only organic!, less fat!, more fat!, plant-based!, paleo!, non-GMO!, raw!, Mediterranean!, gluten-free! with dire warnings about what will happen if we fail to follow that plan exactly. (I feel particularly sympathetic to parents of young children, who are already stressed out about the incredible day-to-day challenges of raising them in a difficult economy. Shaming them if they’re buying most of their food in bulk once or twice a month at Costco instead of shopping exclusively for their children at Whole Foods is outrageous. In fact, the very ability to make choices about what we eat is a privilege not shared by a huge proportion of the planet’s population…but that’s a subject for another post).
For the average person untrained in science, nutrition, or medicine, the challenge of wading through this mountain of advice on how one “should” eat, sorting out the good advice from the bad, can be daunting. With so many options it’s easy to succumb to decision fatigue–or default to way too many meals at fast food joints.
Diet and health gurus are counting on this. They offer people a simple solution: follow my “movement”, follow my advice and you don’t have to think for yourself about this; follow my simple “tricks” and you’re guaranteed “health”, “thinness” and a sense of belonging to a righteous movement.
The idea that Native Americans had at least some ancestry from a trans-Atlantic migration has been around since the earliest days of American anthropology. The earliest proponents of this idea looked at the spectacular burial mounds and art from North America and insisted that they could not have been made by the ancestors of the indigenous (or as they put it, “primitive”) peoples they encountered. Obviously, they reasoned, a “Lost Race” of “Moundbuilders” (identified variously as Atlanteans, Europeans, and Israelites) must have been responsible for the great archaeological sites in North America. But systematic excavation of these sites has thoroughly debunked that idea.**
Nevertheless, an idea that there must be a European origin for at least some Native Americans has persisted in various forms. In its modern iteration, this idea is known as the “Solutrean Hypothesis.” The Solutrean hypothesis claims that the Clovis people, the makers of the earliest known stone tools in the Americas, were the cultural and biological descendants of the Solutrean peoples of southwest coastal Europe.
Did you know that Darwin’s children doodled on his “Origin” manuscript? You can see their sketches here.
Creationists tend to raise the same objections to evolution over and over again. Here are Phil Plait’s responses to a number of them (h/t to Washington Post for the last two links ).
If I’m being completely honest, I found “On the Origin of Species” to be a rather boring book. World-changing, but not a thrilling read. “The Voyage of the Beagle”, on the other hand, is fantastic and I highly recommend it! You can download the full book for free here.
What does it mean to be human? Understanding the history of our species helps us answer this question. If you’re a little rusty on your human paleontology, the Smithsonian Museum of Natural History has an excellent, easy to read guide for you.
Help improve science education in your community by visiting the National Center for Science Education’s webpage. They keep track of legislation that threatens science education in public schools, and have resources for community members who want to help.
Finally check out this page to find an event in your town celebrating Darwin today! I’m planning on toasting the great man tonight with a nice bottle of champagne (sent to me by one of my mentors as a congratulatory gift for becoming a professor. It seems fitting!).
