Have you seen the headlines? Skip them You’ve probably seen a lot of headlines lately about autism and various behaviors, ways of being, or “toxins” that, the headlines tell you, are “linked” to it. Maybe you’re considering having a child and are mentally tallying up the various risk factors you have as a parent. Perhaps you have a child with autism and are now looking back, loaded with guilt that you ate high-fructose corn syrup or were overweight or too old or too near a freeway or not something enough that led to your child’s autism. Maybe you’re an autistic adult who’s getting a little tired of reading in these stories about how you don’t exist or how using these “risk factors” might help the world reduce the number of people who are like you. Here’s the bottom line: No one knows precisely what causes the extremely diverse developmental difference we call autism. Research from around the world suggests a strong genetic component[PDF]. What headlines in the United States call an “epidemic” is, in all likelihood, largely attributable to expanded diagnostic inclusion, better identification, and, ironically, greater awareness of autism. In countries that have been able to assess overall population prevalence, such as the UK, rates seem to have held steady at about 1% for decades, which is about the current levels now identified among 8-year-olds in the United States. What anyone needs when it comes to headlines honking about a “link” to a specific condition is a mental checklist of what the article–and whatever research underlies it–is really saying. Previously, we brought you Real vs Fake Science: How to tell them apart. Now we bring you our Double X Double-Take checklist. Use it when you read any story about scientific research and human health, medicine, biology, or genetics. The Double X Double-Take: What to do when reading science in the news 1. Skip the headline. Headlines are often misleading, at best, and can be wildly inaccurate. Forget about the headline. Pretend you never even saw the headline. 2. What is the basis of the article? Science news originates from several places. Often it’s a scientific paper. These papers come in several varieties. The ones that report a real study–lots of people or mice or flies, lots of data, lots of analysis, a hypothesis tested, statistics done–is considered “original research.” Those papers are the only ones that are genuinely original scientific studies. Words to watch for–terms that suggest no original research at all–are “review,” “editorial,” “perspective,” “commentary,” “case study” (these typically involve one or only a handful of cases, so no statistical analysis), and “meta-analysis.” None of these represents original findings from a scientific study. All but the last two are opinion. Also watch for “scientific meeting” and “conference.” That means that this information was presented without peer review at a scientific meeting. It hasn’t been vetted in any way. 3. Look at the words in the article. If what you’re reading contains words like “link,” “association,” “correlation,” or “risk,” then what the article is describing is a mathematical association between one thing (e.g., autism) and another (e.g., eating ice cream). It is likely not describing a biological connection between the two. In fact, popular articles seem to very rarely even cover scientific research that homes in on the biological connections. Why? Because these findings usually come in little bits and pieces that over time–often quite a bit of time–build into a larger picture showing a biological pathway by which Variable 1 leads to Outcome A. That’s not generally a process that’s particularly newsworthy, and the pathways can be both too specific and extremely confusing. 4. Look at the original source of the information. Google is your friend. Is the original source a scientific journal? At the very least, especially for original research, the abstract will be freely available. A news story based on a journal paper should provide a link to that abstract, but many, many news outlets do not do this–a huge disservice to the interested, engaged reader. At any rate, the article probably includes the name of a paper author and the journal of publication, and a quick Google search on both terms along with the subject (e.g., autism) will often find you the paper. If all you find is a news release about the paper–at outlets like ScienceDaily or PhysOrg–you are reading marketing materials. Period. And if there is no mention of publication in a journal, be very, very cautious in your interpretation of what’s being reported. 5. Remember that every single person involved in what you’re reading has a dog in the hunt. The news outlet wants clicks. For that reason, the reporter needs clicks. The researchers probably want attention to their research. The institutions where the researchers do their research want attention, prestige, and money. A Website may be trying to scare you into buying what they’re selling. Some people are not above using “sexy” science topics to achieve all of the above. Caveat lector. 6. Ask a scientist. Twitter abounds with scientists and sciencey types who may be able to evaluate an article for you. I receive daily requests via email, Facebook, and Twitter for exactly that assistance, and I’m glad to provide it. Seriously, ask a scientist. You’ll find it hard to get us to shut up. We do science because we really, really like it. It sure ain’t for the money. [Edited to add: But see also an important caveat and an important suggestion from Maggie Koerth-Baker over at Boing Boing and, as David Bradley has noted over at ScienceBase, always remember #5 on this list when applying #6.] —————————————————————————– Case Study Lately, everyone seems to be using “autism” as a way to draw eyeballs to their work. Below, I’m giving my own case study of exactly that phenomenon as an example of how to apply this checklist. 1. Headline: “Ten chemicals most likely to cause autism and learning disabilities” and “Could autism be caused by one of these 10 chemicals?” Double X Double-Take 1: Skip the headline. Check. Especially advisable as there is not one iota of information about “cause” involved here. 2. What is the basis of the article? Editorial. Conference. In other words, those 10 chemicals aren’t something researchers identified in careful studies as having a link to autism but instead are a list of suspects the editorial writers derived, a list that they’d developed two years ago at the mentioned conference. 3. Look at the words in the articles. Suspected. Suggesting a link. In other words, what you’re reading below those headlines does not involve studies linking anything to autism. Instead, it’s based on an editorial listing 10 compounds [PDF] that the editorial authors suspect might have something to do with autism (NB: Both linked stories completely gloss over the fact that most experts attribute the rise in autism diagnoses to changing and expanded diagnostic criteria, a shift in diagnosis from other categories to autism, and greater recognition and awareness–i.e., not to genetic changes or environmental factors. The editorial does the same). The authors do not provide citations for studies that link each chemical cited to autism itself, and the editorial itself is not focused on autism, per se, but on “neurodevelopmental” derailments in general. 4. Look at the original source of information. The source of the articles is an editorial, as noted. But one of these articles also provides a link to an actual research paper. The paper doesn’t even address any of the “top 10″ chemicals listed but instead is about cigarette smoking. News stories about this study describe it as linking smoking during pregnancy and autism. Yet the study abstract states that they did not identify a link, saying “We found a null association between maternal smoking and pregnancy in ASDs and the possibility of an association with a higher-functioning ASD subgroup was suggested.” In other words: No link between smoking and autism. But the headlines and how the articles are written would lead you to believe otherwise. 5. Remember that every single person involved has a dog in this hunt. Read with a critical eye. Ask yourself, what are people saying vs what real support exists for their assertions? Who stands to gain and in what way from having this information publicized? Think about the current culture–does the article or the research drag in “hot” topics (autism, obesity, fats, high-fructose corn syrup, “toxins,” Kim Kardashian) without any real basis for doing so? 6. Ask a scientist. Why, yes, I am a scientist, so I’ll respond. My field of research for 10 years happens to have been endocrine-disrupting compounds. I’ve seen literally one drop of a compound dissolved in a trillion drops of solvent shift development of a turtle from male to female. I’ve seen the negative embryonic effects of pesticides and an over-the-counter antihistamine on penile development in mice. I know well the literature that runs to the thousands of pages indicating that we’ve got a lot of chemicals around us and in us that can have profound influences during sensitive periods of development, depending on timing, dose, species, and what other compounds may be involved. Endocrine disruptors or “toxins” are a complex group with complex interactions and effects and can’t be treated as a monolith any more than autism should be. What I also know is that synthetic endocrine-disruptors have been around for more than a century and that natural ones for far, far longer. Do I think that the “top 10″ chemicals require closer investigation and regulation? Yes. But not because I think they’re causative in some autism “epidemic.” We’ve got sufficiently compelling evidence of their harm already without trying to use “autism” as a marketing tool to draw attention to them. Just as a couple of examples: If coal-burning pollution (i.e., mercury) were causative in autism, I’d expect some evidence of high rates in, say, Victorian London, where the average household burned 11 tons of coal a year. If modern lead exposures were causative, I’d be expecting records from notoriously lead-burdened ancient Rome containing descriptions of the autism epidemic that surely took it over. Bottom line: We’ve got plenty of reasons for concern about the developmental effects of the compounds on this list. But we’ve got very limited reasons to make autism a focal point for testing them. Using the Double X Double-Take checklist helps demonstrate that. By Emily Willingham, DXS managing editor
Today’s post is long. It’s long because it involves the winding path that science can take from ignition to exploding into the public view… and how the twists and turns in that path can result in a skewed representation and understanding of the science. Read the whole thing. It focuses on an example that involves autism–which seems to pop up in skewed representations every day–but certainly this path from science to you, the consumer, happens with scientific information in general. The author is Jess, who blogged this originally at “Don’t Mind the Mess” and graciously gave us permission to reproduce it here. Jess, an attorney with a B.S. in biochemistry, parent of an autistic child and brand new baby, and self-described “Twitter fiend,” tweets as @JessicaEsquire.
I am putting my foot down.
As the parent of an autistic child I hear a lot about vaccines and about half a million other things that people think cause autism.
I’m hyperaware of the attention autism gets in the media. So I know about the CDC’s new stats on autism rates. I know about the debate on whether the increase in autism is due to more awareness and diagnosis or more actual occurrences. (Personally, I find the former to be a serious factor, though who’s to say how much.) And I see all the articles that come out week after week about the millions of things that are linked to autism.
There’s a recurring problem here. Valuable research is done. Research is disseminated. Information is reported. Articles are read. Findings are spread. What starts in a lab ends up in a Facebook status. What starts as truth ends up as mistruth in something like a child’s game of telephone. Along the way, piece by piece, truth fades away in favor of headlines and pageviews and gossip.
It’s getting just plain stupid. I’m starting to suspect these articles have nothing to do with serious research but with a search for traffic and hype, an attempt to ride the wave of a trendy topic as concerned parents read every horror story they can find.
A particularly egregious one came up recently. This one doesn’t just cite some random correlation. This one is just plain making things up. The problems here just pile one on top of the other. So let’s consider it piece by piece, a case study in how real research becomes misinformation.
Part One: Research
It starts with scientists. It starts with research. They write up their findings and publish them in a peer-reviewed scientific journal. In this case there are several papers published over a few years about chemicals and their link to brain development. They cover a wide variety of issues and present a wide variety of conclusions. All of them suggest further study.
Maybe they have bad methodology or use statistics incorrectly. Only a few people would ever know the difference. That’s not my concern today. Bad science is one thing, but bad information on good science is another. So let’s assume we have good, solid science in this research.
Part Two: The Conference
Scientists and researchers with similar interests get together and discuss their findings. It’s not that difference from any other conference. There are panels and presentations.
Part Three: The Op-Ed
Next, a group that works on environmental hazards for children publishes a paper. Not a research study but an op-ed in a peer-reviewed journal. In this op-ed they review the conference from Part Two and encourage the study of environmental factors and their relationship to neurodevelopment disorders. Autism is one of many neuro-ish disorders and is mentioned by name in the piece and its title. It’s unclear to me why they zero in on autism. They have a couple vague pieces of evidence that are autism-specific, but the vast majority of what they’re looking at has never been demonstrated to have any kind of relationship to autism, not even a correlation.
Problem #1 is the unnecessary autism name-checking. Problem #2 is much worse, it’s the list of 10 chemicals they suggest for future study. The list itself isn’t a bad idea, I guess. They’re suggesting places for potential research, which certainly needs to be done. But it does reek a little bit of the kind of thing magazines do, you know what I mean, 10 Ways To Get Your Guy All Fired Up! and such. Still, it’s their prerogative.
So let’s examine their evidence for these suggestions. They cite at least one paper for each of these chemicals. I checked them all. The vast majority of them have never shown any connection to Autism (or even ADHD, another diagnosis they name-check). In fact, many of them show that with exposure to these chemicals, the outcome differentials between exposure and non-exposure is 5 IQ points.
FIVE IQ POINTS. Statistically significant? Perhaps. Practically important for a parent? No.
IQ itself is a strange and vague thing. And 5 points isn’t going to move your super-genius down to the level of an average person They’d still be a super-genius. And adding 5 points to someone with severe deficits isn’t going to make them average, either. It’s hard to imagine what difference you’d see between two people whose IQ’s are 5 points apart.
Such statistical differences may well be a sign to warrant further study. And they may be a sign that these chemicals affect neurological development. But it’s getting a bit ahead of ourselves to say they are suspected of being tied to autism. Many of these papers are in areas of research that are just beginning. Many of them involve homogeneous groups (for example, all the participants are Mexican-American migrant workers) which makes issues of genetics and heredity very difficult to account for. Many involve parents self-reporting by filling out surveys rather than having the children examined by professionals.
Let’s be fair. These are the very beginnings of research. You’ll need to do all sorts of rigorous testing and consideration to make real connections. Of course more research is needed. And it’s important that we keep that in mind as we move forward.
(Though, of course, no one else will.)
Part Four: The Press Release
The op-ed is about publicity so it’s the beginning of the problem. But it gets worse.A press release comes out with the list of ten chemicals and already the twisting starts. These are chemicals suggested for further research, but suddenly they’re a ”List of the Top Ten Toxic Chemicals Suspected to Cause Autism and Learning Disabilities.” This, unsurprisingly, is the headline you’ll see all over the internet when news organizations report on the press release. Already it’s turned from suggestions for research into a watchlist.
It gets worse. The press release has this second headline:
The editorial was published alongside four other papers — each suggesting a link between toxic chemicals and autism.
No, actually that’s not at all accurate.
Let’s start with the first paper, which examines the possibility of a connection between maternal smoking and autism. What’s their conclusion?
The primary analyses indicated a slightly inverse association with all ASDs[.]
What does that mean? Among the autistic kids vs. regular kids, there was actually LESS maternal smoking in the autism group. The paper does point out that when it comes to “subgroups,” for instance high-functioning ASD or Asperger’s, there may be a possibly positive relationship. But there are so many caveats I can’t even get to them all. Let’s just take this one:
The ASD subgroup variables were imperfect, relying on the child’s access to evaluation services and the documentation by a myriad of community providers, rather than direct clinical observation.
This means that when they’re saying some groups of ASD kids may have this relationship, they didn’t actually classify these kids. They never saw these kids. They’re relying on data collected by other people. Not even by a consistent set of people. It comes from 11 different states and who knows how many providers. Who’s to say how accurate any of it is. And who’s to say whether these kids are correctly classified at their particular place on the spectrum.
So take all that with a whole jar full of salt and you’re still looking at, overall, no connection with smoking. If anything, the data would indicate smoking has LESS autism rather than more.
After this there are 2 papers on the same chemical. One of them does not contain the word “autism” anywhere. (One of its references has it, but nowhere does it appear in the text of their paper.) The second paper is better. It focuses on the chemical’s effects in particular processes which have been linked to autism. This is very micro-scale science, there are no people involved, just cells and chemicals. It’s important research, but there’s a long stretch between cellular interactions and a person’s diagnosis. It didn’t involve any analysis with autistic individuals. This is certainly the most useful paper of the bunch by a long shot, but it still just sets the stage for further research.
The fourth paper is a review. That means it asserts no new information but summarizes the research on a particular issue, specifically pesticides and autism. Technically I suppose it does assert a link, but none of this is new information.
So I think we’ve pretty much destroyed the headline in that press release. There were not 4 articles suggesting a connection between chemicals and autism.
Is it likely that the writers who take this press release and write articles on it are going to read the papers it cites? Are they going to realize that what they’re saying isn’t actually true? They should. Of course they should. But they don’t.
This list has chemicals suspected of being tied to neurological development. And we should just leave it at that. It’s not that they shouldn’t be studied. They should. But we shouldn’t be throwing out buzzwords like ADHD and Autism when the research doesn’t show any firm data.
Part Five: News Articles
This is a process, though. First research, then op-ed, then press release and finally news articles. So what’s the headline of our news article? “Top 10 Chemicals Most Likely to Cause Autism and Learning Disabilities.” Guilty of serious fearmongering, no? A more accurate title may be: Researchers propose list of chemicals potentially tied to neurological development for further study. But I doubt anyone’s going to write that.
The article itself, to be fair, is full of caveats. The reasons for the increase in autism are “controversial.” There is a “gap in the science.” But then you get a sentence like this:
But clearly, there is more to the story than simply genetics, as the increases are far too rapid to be of purely genetic origin.
Clearly? Clearly says who? What source says it’s too rapid? The author certainly isn’t a reliable source. She is Robyn O’Brien, a writer for Prevention who posted this article. Her scientific credentials are nonexistent. She is a former financial analyst who now writes about the food industry. She has an MBA, and her undergraduate was in French and Spanish.
Full disclosure: I have a B.S. in Biochemistry, but I feel I’m unqualified to write this article. I’d much rather it be written by someone with a PhD. I’m married to a PhD, which has given me a lot more exposure to science since leaving school, but I fully acknowledge that I shouldn’t be the one doing this. I know how to read a scientific article and examine its conclusions, but I certainly am not someone who can tell you if their methods and analysis are correct.
But I’m talking because there aren’t enough people talking about it. Because the PhD’s aren’t generally science writers. They are scientists. They write about their research in journals, not in the newspaper. And certainly not on a blog for a healthy living magazine.
The author goes on to restate the inaccurate subheadline of the press release verbatim.
In the end she suggests things like buying organic produce, opening your windows and buying BPA-free products.
This is part 5 of our process, but it’s where many of us start. Many of us will only read this article and not the press release or the op-ed or the research papers. Most of us aren’t qualified to do so, all we have is this article. Well, we have that and what other people tell us. Which leads us to our next step.
Part Six: Readers
The article is frustrating, but I can only get so mad. She is saying what the scientists told her to say. She has even included some cautionary language. The problem is that when writing for laymen, you have to be careful.
And with AUTISM? You have to be really careful. Just for you I’m going to venture into the comments to this article to show you how people have responded.
–How about we quit injecting our kids with aluminum, formaldehyde and the rest of the toxic stew that they call vaccines — we bypass every natural defense our bodies have (skin, saliva, stomach acid) to put these things directly in the blood stream.
–Thank you Robyn for always providing sound information to continue guiding our decisions.
–What about heavy metals like Arsenic that are trapped in soils that our “organic” brown rice is growing in to be made into brown rice syrup to sweeten organic foods and baby formula? Not to mention the reports coming in regarding the radiation and contamination from Fukushimi that has reached the west coast an is spreading across this country in the produce and even the pollen…
–Unvaccinated children are some of the healthiest little people on the planet. As far as the Autism link, who really knows but why risk it.
–Thank you for this information. It confirms to me that we should keep doing what we are doing. It also helps me to enforce our no shoes policy in our home. Some people are so disrespectful and just don’t take them off and I hate to sound like a nag and ask even though they already know its what we prefer.
Thankfully there are some people in there who take the writer to task, but how is a reader to trust any one commenter over another? You have no way of knowing from a comment what someone’s experiences or qualifications are.
There’s a reason we need responsible scientific reporting. I’m all for the open dissemination of information, but I’m also aware of what happens when people read something they don’t understand.
I encountered this FB conversation the other day. Usually I overlook such things but I could not help myself. I jumped in. I tried hard to be polite and present facts. When all that was over, no one was convinced. The response?
Enough articles on vaccines and people are scared even without evidence. Enough headlines and people don’t bother reading articles. It doesn’t matter how much is retracted or debunked, the damage is done.
We need responsible science reporting. We need responsible reporting, period. I’ve seen plenty of lazy articles on Supreme Court opinions that lead me to read the opinion myself only to realize that they’ve stated the conclusions all wrong.
I don’t want to go on all day, but I do feel like it’s important for us to put our foot down and demand better.
We aren’t all scientists. But we can ask for science writers with the appropriate qualifications. We can ask for links and citations in their articles. (I spent quite some time tracking everything down for this post, and luckily I’m relatively familiar with looking up scientific articles online.) We can ask for articles that show failed connections. It doesn’t all have to be “Autism linked to X” there’s plenty of “Autism not linked to Y” that happens in these studies but you never see that, do you?
As for us laymen, we have to find our own trusted experts. Ask your pediatrician. And if your pediatrician’s not qualified (most of them are MD’s but not PhD’s) ask them if they have a trusted source. Track down specialists in Autism with PhD’s and ask them what they think of the research. Find reliable books and articles and spread them to your friends. We can’t necessarily do a lot, but we can do our part to stop the spread of misinformation and demand better.
These views are the opinion of the author and do not necessarily either reflect or disagree with those of the DXS editorial team.
How often have you wished for an extra hour or extra day to get everything you need done? At the Autism Science Foundation (ASF), we want to make the most of this special leap day by using it to help autism science leap forward.
Thanks to your support, for the last two years we have provided funding for autism stakeholders (parents, individuals with autism, teachers, students, etc) to attend the International Meeting for Autism Research (IMFAR). All donations made today, February 29, 2012, will go directly to our IMFAR Travel Grants program, helping us provide more scholarships to IMFAR 2012 in Toronto where they will share their real world autism experience with scientists. These stakeholders will then bring the latest autism science back into our communities helping the science take a giant leap forward.
After attending IMFAR, past grant recipients have: - Organized a five day autism science seminar at Barnard College - Presented critical autism research information to nurses in Philadelphia - Produced multiple blog posts that reached thousands of readers around the world - Organized an autism awareness club and speaker series at Yale College
And thanks to a generous donor, all donations made today (February 29, 2012) will be matched dollar for dollar for an extra big leap.
The Autism Science Foundation was founded in 2009 as a nonprofit corporation organized for charitable and educational purposes, and exempt from taxation under section 501(c)(3) of the IRS code.
The Autism Science Foundation’s mission is to support autism research by providing funding and other assistance to scientists and organizations conducting, facilitating, publicizing and disseminating autism research. The organization also provides information about autism to the general public and serves to increase awareness of autism spectrum disorders and the needs of individuals and families affected by autism.
This edition of the Notable Women in Science series presents modern astronomers. Many of these women are currently working in fields of research or have recently retired. As before, pages could be written about each of these women, but I have limited information to a summary of their education, work, and selected achievements. Many of these blurbs have multiple links, which I encourage you to visit to read extended biographies and learn about their current research interests.

She is currently Professor of Physics and Department Chair at the Open University, England.
Featured today are 10 more women who broke boundaries by their presence in physics. They lived from 1711 to 2000. While I again limited information to one paragraph, I tried to highlight how they got their start, what universities, family members, and scientists were supportive of them. For these women, without the support of fathers, mothers, husbands, and mentors (all male with one exception) their life in science would not have happened. While barriers are not as difficult today as they were at the times these women made their way, it is a testament to what can be done when families and scientists support each other. These women are an inspiration and I hope you look up more information for them. In addition, I’d love to hear who your favorite women in science are in the comments.
Laura Bassi (1711-78) lectured on science until a few hoursbefore her death. An Italian scientist of international fame and one of the first women physicists in western history, Dr. Bassi earned her doctorate in philosophy and science through public debate from the University of Bologna. The University of Bologna offered Dr. Bassi a position in an effort to be known as a leader in women’s education. Unfortunately, this forward step was not acceptable to much of the rest of the world’s academic community and required stipulations to Dr. Bassi teaching. However, she countered these limitations with determination and passion. Her appointment to full membership in the Bendettini Academics also deterred some naysayers of Dr. Bassi’s involvement in research and teaching. In order to further her career, she married. A married woman could achieve more than a single woman at that time. Her death in 1778 was unexpected, especially as she had participated in an Academy of Sciences lecture on a few hours before.
Margaret Eliza Maltby (1860-1944) was a recognized scientistand advocate for women in science.She overcame the education offered to women by taking extra courses in order to attend Oberlin College and receive a B.A. She studied with the Art Students’ League in New York City to explore her interest in art and then taught high school before enrolling as a “special student” at the Massachusetts Institute of Technology (MIT), receiving her B.S. Oberlin recognized this extra effort by awarding Dr. Maltby an M.S. She became a physics instructor at Wellesley College. She was encouraged in her graduate students by an AAUW fellowship to attend Göttingen University, which culminated in Dr. Maltby being the first American woman to receive a Ph.D. in physics from any German university. Dr. Maltby worked as an instructor, a researcher, and administrator in many universities and colleges in the U.S. and abroad. Her stature as a scientist was acknowledged with her entry in the first edition of AmericanMen of Science. She also was active in the AAUW, advocating for women to gain education and enter scientific fields. After her retirement from university life, she maintained her interest in the arts.
Irène Joliot-Curie (1897-1956) was a Nobel Prize Laureate for “artificial radioactivity.”Born to the woman every person thinks of as the epitome of a woman in science, Marie Curie, Irène had an extremely close relationship with her paternal grandfather. Her schooling was outside of the standard schooling type, her first years at home and her latter years in a science and math heavy co-operative school of Madame Curie’s colleagues. She received her Bachelor’s degree from the Collège Sévigné and went on to study at the Sorbonne. She received her doctorate in 1925 based on work with her mother at the Radium Institute of the Sorbonne. She married Frédéric Joliot, another research assistant of Madame Curie’s. Dr. Joliot-Curie continued her research, interrupted by a stint as Undersecretary of State for Scientific Research, one of the first high government posts to be offered to a woman. She worked as a professor for the Sorbonne and director of the Radium Institute, but was not admitted to the Academy of Sciences due to discrimination despite her work. She died, like her mother, of acute leukemia. Her scientific work was complemented by her love of physical activity and motherhood.
Katharine Burr Blodgett (1898-1979) was a woman with an amazing number of firsts. Born to a widow, she was a world citizen in her formative years, attended high school at a private school in New York City, won a scholarship to attend Bryn Mawr, and graduated second in her class there. She received her Master’s degree from the University of Chicago, then headed off to work with Nobel Laureate Irving Langmuir at General Electric (GE) and becoming the first woman research scientist there. She was able to work with Nobel Laureate Sir Ernest Rutherford and earn her Ph.D. from Cambridge University as the first woman to earn a doctorate from Cambridge. She returned to GE. During her career, she invented many applications and is credited with six patents. She achieved much when many women did not, but her work was de-valued in the media. She did earn recognition from her peers, including the ACS Garvan Medal, the Photographic Society of America Progress Medal, and a day named after her in her hometown of Schenectady, NY. In addition to her scientific life, she enjoyed gardening, civic engagement, acting, and “dart[ing] about Lake George in a fast motor boat.”
Astrophysicist Charlotte Emma Moore Sitterly (1898-1990) was an authority on sun composition. She started her career as an excellent student with extracurricular interests, attending Swarthmore College to earn her B.A. Upon graduation, she accepted a position as a mathematics computer at Princeton University Observatory, one of the few employment opportunities available to science inclined women at the time. A stint at the Mount Wilson Observatory led to results published a 1928 monograph which was considered the authoritative work on the solar spectrum for four decades. She received her Ph.D. from the University of California, Berkeley in 1931. Her work earned her the Annie J. Cannon Prize, Silver and Gold Medals from the Department of Commerce, and several honorary doctorates in the U.S. and abroad. She was the first woman elected foreign associate by the Royal Astronomical Society of London. Her enthusiasm for her work continued until her death.
Nuclear Physicist Maria Goeppert-Mayer (1906-1972) was the second woman to win the physics Nobel. Her early education was public education for girls followed by a private school founded by suffragettes. Circumstances led Dr. Goeppert-Mayer to take her exiting exams a year early, passing them she attended the University of Göttingen for her college education in mathematics. She continued to study physics at the University of Göttingen, earning her Ph.D. in 1930. She also married that year. The couple moved to America in hopes of better career trajectory for Dr. Goeppert-Mayer. Finding a position was difficult. When she had her first child, she stayed home with her for one year, then returned to research. While her positions were always part-time and not well recognized, she grew a well-respected network of collaborators. This network led to work with Hans Jensen which won her the Nobel Prize, shared with Jensen. Her network also eventually led to a full professorship position after 20 years of volunteer work. During this time, her health began to fail. She persevered with her work, publishing her last paper in 1965. The American Physical Society established an award in her honor in1985.
Gertrude Scharff Goldhaber (1911-1998) was a respected researcher.She grew up in a time in Germany where girls were expected to become schoolteachers. She had a fascination with numbers, and eventually studied physics at the University of Munich, receiving her PhD in 1935. She fled Germany during the rise of the Nazis due to being Jewish, arriving in the United States and becoming a citizen in 1944. She had a wide involvement in the various National Laboratories studying nuclear physics. She also maintained several committee positions in the science community. She was also a strong advocate for women in the science community, forming a Women in Science group at Brookhaven National Lab and supporting other similar groups elsewhere. After her retirement from research, she continued interests in the history of science, outdoor activities, and art.
Physicist, Molecular Spectroscopist Leona Woods MarshallLibby (1919-1986)Leona Woods grew up on a farm and was known for her inexhaustible energy. She attained her B.S. in chemistry from the University of Chicago when she was only 19 years old, and earned her PhD 5 years later. She worked as the only woman and youngest member of the Chicago Metallurgical Laboratory, a secret war group led by Enrico Fermi who built the world’s first nuclear fission reactor during her graduate work. Dr. Woods’ expertise was essential to the undertaking. She married another member of her team. She hid her first pregnancy until 2 days before her son’s birth. She took one week off before returning to work. Childcare was provided by her mother and sometimes Fermi’s bodyguard, John Baudino. Dr. Marshall was encouraged by Fermi as a female physicist. In the late 1950s, Dr. Marshall was divorced from her husband, pursuing her own career. In the early 1960s, Dr. Marshall moved to Colorado to work and married Willard Libby. Her mind was always considering any number of problems from many angles. She worked up until her death and was honored posthumously for her work, along with Lise Meitner, Marie Curie, and Irene Joliot-Curie.
Chien-Shiung Wu (1912-1997) was a foremost experimental physicist of modern era. She was encouraged as a girl to pursue her schooling as far as possible. This led her to teaching training, which lacked science so she taught herself physics, chemistry, and mathematics. She graduated high school with the highest grades in her class, earning her a place at the National Central University in Nanjing. She taught and did research upon graduation, then moved to the United States to pursue graduate studies. She earned her Ph.D. from the University of California – Berkeley in 1940, four years after leaving China. She was known for her expertise in nuclear fission and was consulted by top scientists. Despite this, her gender and nationality hindered her finding appropriate employment due to discrimination on both accounts. She married and started a teaching career, although she missed research. Upon the recommendation of Ernest Lawrence, she received offers from several Ivy League schools who were not accepting female students at the time. She became Princeton’s first woman instructor at that time. She was offered several positions, including back in China, but chose to remain in the U.S. to raise her son. She was unable to return to China until 1973. She worked at Columbia for many decades and earned accolades for her work.
Xide Xie (1921-2000) is a woman in China who needs no introduction. Her early life involved much moving due to war and ill health, during which she taught herself English, calculus, and physics. She graduated in 1942 with a degree from Xiamen University. She moved to the United States to receive her master’s degree from Smith College in 1949 and her Ph.D. in physics from M.I.T. in 1951. She married in England and returned to China, despite the political climate. She taught and did research at the prestigious Fudan University. During the Cultural Revolution of 1966-76, she was detained, publicly humiliated, and endured breast cancer. After this upheaval, she returned to Fudan University, growing the physics department and achieving more esteemed positions in the University and government. She had also remained connected to her family, caring for her husband through lengthy illness. Her achievements were internationally recognized.
Benedettini Academics were a select group of scholars from the Academy of Sciences created and named for Pope Benedict XIV to conduct research and present it annually at Academy meetings. This appointment escalated the prestige of the scientist above that given by being a member of the Academy of Sciences.
American Association for University Women (AAUW): Margaret Maltby received the European Fellowship from the Association of Collegiate Alumnae, which became the AAUW. This fellowship was specifically intended to help American women pursue graduate studies to circumvent rules that did not allow women to enroll in coeducational universities or earn graduate degrees.
The Nobel Prize is an international award given in several fields. It is one of the most prestigious awards for scientists in the eyes of the public.
The Garvan Medal is an award from the American Chemical Society to recognize distinguished service to chemistry by women chemists.
