It’s tempting to cast the role of women in STEM (Science, Technology, Engineering, and Math) as one of struggles and battles because of their sex, rather than as one of contributions because of their minds. But for Women’s History Month and this Diversity in Science Carnival #14, our focus is the role of women in the enterprise of STEM. There’s more to a woman than her sex and her struggles in science–there is, after all, the enormous body of work women have contributed to science.
Our history is ongoing, but we can start with a look back. Thanks to the efforts of the Smithsonian Institution Archives, we can put faces to the names of some of the female STEMmers of history. In a presentation of photographs in an 8 by 9 space, we can see the images of 72 women who contributed to the enterprise of STEM, many of them involved with the Smithsonian in some capacity. As their clothes and the dates on the photos tell us, these women were doing their work in a time when most women didn’t even wear pants.
Some are Big Names–you’ve probably heard of Marie Curie. But others are like many of us, women working in the trenches of science, contributing to the enterprise of STEM in ways big and small. Women like Arlene Frances Fung, whose bio tells us she was born in Trinidad, went to medical school in Ireland, and by 1968 was engaged in chromosome research at a cancer institute in Philadelphia. From Trinidad to cancer research, her story is one of the millions we could tell about women’s historical contributions to science, if only we could find them all. But here there are 72, and we encourage you to click on each image, look at their direct gazes, ponder how their interest in science and knowledge trumped the heavy pressures of social mores, and discover the contributions these 72 women made, each on her own “little two inches wide of ivory.”
For more on historical and current women in science, you can also see Double X Science’s “Notable Women in Science” series, curated by Adrienne Roehrich.
And then there are the women STEMmers of today, who likely are, according to blogger Emma Leedham writing at her blog Pipettes and Paintbrushes, still underpaid. Leedham also mulls here what constitutes a role model for women–does it require being both a woman and a scientist, or one or the other?
Laurel L. James
Laurel L. James, writing at the University of Washington blog for the school’s SACNAS student chapter, answers with her post, “To identify my role as a woman in science: I must first honor my mother, my family and my past.” Her mother was the first “Miss Indian America,” and Laurel is a self-described non-traditional student at the school, where she is a graduate student in forest resources. She traces her journey to science, one that involved role models who were not scientists but who, as she writes, showed her “how to hang onto the things that are important with the expectation of getting something in return all the while, persevering and knowing who you are; while walking with grace and dignity.” I’d hazard that these words describe many a woman who has moved against the currents of her society to contribute something to the sciences.
A great site, Steminist.com, which features the “voices of women in science, tech, engineering, and math,” runs a series of interviews with modern-day STEMmers, including Double X Science’s own Jeanne Garbarino, and Naadiya Moosajee, an engineer and cofounder of South African Women in Engineering. You can follow Naadiya on Twitter here. Steminist is also running their version of March Madness, except that in honor of Women’s History Month, we can choose “Which historical women in STEM rock (our) world.” The 64 historical STEMinists in the tourney are listed here and include Emily Warren Robling (left), who took over completion of the Brooklyn Bridge when her husband’s health prevented his doing so; she is known as the first woman field engineer. Double X Science also has a series about today’s women in science, Double Xpression, which you can find here.
Today, you can find a woman–or many women–in STEM just about anywhere you look, whether it is as a government scientist at NOAA like Melanie Harrison, PhD, or at NASA. It hasn’t always been that way, and it can still be better. But women have always been a presence in STEM. In the 18thand 19th centuries, astronomer Caroline Herschellabored away through the dark hours of just about every night of her adult life, tracking the night sky. Today, women continue these labors, and STEM wouldn’t be what it is today without women like Herschel willing to stay up all night with the skies or spend days on end in the field or lean over a microscope for hours just to add a tiny bit more to what we know about our world and our universe.
For women in science, we’re there–at night, in the lab, in the field–because we love science. But as the non-science role models seem to tell us, we stick to it–and can stick with it–because we had role models in and out of science who showed us that regardless of our goals, our attitudes and willingness to move forward in spite of obstacles are really what drive us to success in STEM careers. Among the links I received for this carnival was one to Science Club for Girls, which is sponsoring a “Letter to My Young Self” roundup for Women’s History Month. The letters I’ve read invariably have that “stick with it” message, but one stood out for me, and I close with a quote from it.
It’s a letter by Chitra Thakur-Mahadik, who earned her PhD in biochemistry and hemoglobinopathy from the University of Mumbai and served as staff scientist a Mumbai children’s hospital for 25 years. She wrote to her younger, “partially sighted” self that, “The future is ahead and it is not bad!” She goes on to say, “Be fearless but be compassionate to yourself and others… be brave, keep your eyes and ears open and face the world happily. What if there are limitations? Work through them with awareness. —Yours, Chitra”

Stay tuned for the April Diversity in Science Carnival #15: Confronting the Imposter Syndrome. This topic promises to resonate for many groups in science. I’m pretty sure we’ve all felt at least of twinge of imposter syndrome at some point in our education and careers. Your editor for this carnival will be the inimitable Scicurious, who blogs at Scientific American and Scientopia.
UPDATE: Carnival #15 is now available! Go read about imposter syndrome, why it happens, who has it, and what you can do about it.
In a victory for the dense-breast patient movement, Governor Jerry Brown (D-CA) signed legislation last week requiring that doctors who discover that women have dense breasts on mammography must inform women that: §dense breasts are a risk factor for breast cancer; §mammography sees cancer less well in dense breasts than in normal breasts; and §women may benefit from additional breast cancer screening. The California law goes into effect on April 1, 2013. It follows four states (Connecticut, Texas, Virginia, and New York) with similar statutes. All have enjoyed solid bipartisan support. Rarely do naysayers or skeptics speak up.
Young women who are leading the charge often bring lawmakers the story of a young constituent, diagnosed with a very aggressive, lethal cancer that was not shown on film-screen mammography. The Are You Dense? patient advocacy group engages patients on Facebook, where women share their experiences with breast cancer, organize events, and lobby for legislation. Individual radiologists work with the advocacy groups, but many radiology groups and breast surgeons do not endorse these laws.
A Closer Look at Breast Cancer Data
Living in an age when information is viewed as an entitlement, knowledge, and power, many physicians find it hard to argue against a patient’s right to know. Can sharing information be a mistake? Some epidemiologists think so. Otis W. Brawley, MD, FACP, Chief Medical & Scientific Officer, American Cancer Society, says: “I really worry when we legislate things that no one understands. People can get harmed.” Numerous issues have to be worked out, according to Brawley. For one, he explains: “There is no standard way to define density.” Additionally, “even though studies suggest that density increases the risk of cancer, these cancers tend to be the less serious kind, but even that is open to question,” Brawley says. “We in medicine do not know what to do for women who have increased density.”
A study of more than 9,000 women in the Journal of the National Cancer Institute revealed that women with very dense breasts were no more likely to die than similar patients whose breasts were not as dense. “When tumors are found later in more dense breasts, they are no more aggressive or difficult to treat,” says Karla Kerlikowske, MD, study coauthor, and professor of medicine and epidemiologist at the University of California San Francisco. In fact, an increased risk of death was only found in women with the least dense breasts.
The trouble is what is known about dense breasts is murky. Asked whether he backs advising women that dense breasts are a risk factor for breast cancer, Anthony B. Miller, MD, Co-Chair of the Cancer Risk Management Initiative and a member of the Action Council, Canadian Partnership Against Cancer, and lead investigator of the Canadian National Breast Cancer Screening Study, says: “I would be very cautious. The trouble is people want certainty and chances are whatever we find, all we can do is explain.”
Women in their forties, who are most likely to have dense breasts (density declines with age) may want to seek out digital mammography. In studies comparing digital mammography to film-screen mammography in the same women, digital mammography has been shown to improve breast cancer detection in women with dense breasts. Findingsfrom the Digital Mammographic Imaging Screening Study, showed better breast cancer detection with digital mammography. But digital mammography is not available in many areas. Moreover, Miller explains: “We do not know if this will benefit women at all. It is very probable that removal of the additional small lesions will simply increase anxiety and health costs, including the overdiagnosis of breast cancer, and have no impact upon mortality from breast cancer.”
Additional imaging studies sound attractive to people convinced that there is something clinically significant to find. But as I pointed out in my last post, many radiologists and breast physicians contend that there is no evidence that magnetic resonance imaging or any other imaging study aids breast cancer screening in women with dense breasts. Brawley notes: “These laws will certainly lead to more referral for MRI and ultrasound without clear evidence that women will benefit (lives will be saved.) It’s clear that radiologists will make more money offering more tests.” Miller adds: “A number of doctors are trying to capitalize on this and some of them should know a lot better.”
Many Advocates Question More Tests, Statutes
Even though the “Are You Dense?” campaign has been instrumental in getting legislation on the books across the county, other advocacy groups and patient advocates want research, enhanced patient literacy about risks and benefits of procedures. Many recall mistakes made that led women down the path of aggressive procedures. In that group is the radical Halsted mastectomy, used widely before systematic study, but once studied, found no better than breast-conserving surgery for many cancers, and bone marrow transplants, also found to be ineffective, wearing, and costly.
Jody Schoger, a breast cancer social media activist at @jodymswho engages women weekly on twitter at #bcsm, had this to say on my blog about the onslaught of additional screening tests:
“What is needed is not another expensive modality… but concentrated focus for a biomarker to indicate the women who WILL benefit from additional screening. Because what’s happening now is an avalanche of screening, and its subsequent emotional and financial costs, that is often far out of proportion to both the relative and absolute risk for invasive cancer. I simply don’t think more “external” technology is the answer but one that evolves from the biology of cancer.”
Eve Harris @harriseve, a proponent of patient navigation and patient literacy, challenged Peter Ubel, MD, professor of business administration and medicine, at Duke University, on his view of the value of patient empowerment on the breast density issue. In a post on Forbes, replicated in Psychology Today, Ubel argued that in cases where the pros and cons of a patient’s alternatives are well known, for example, considering mastectomy or lumpectomy, patient empowerment play an important role. “But we are mistaken to turn to patient empowerment to solve dilemmas about how best to screen for cancer in women with dense breasts,” he writes.
Harris disagrees, making a compelling case for patient engagement:
“I think that we can agree that legislative interference with medical practice is not warranted when it cannot provide true consumer protection. But the context is the biggest culprit in this situation. American women’s fear of breast cancer is out of proportion with its incidence and its mortality rate. Truly empowering people—patients would mean improving health literacy and understanding of risk…”
But evidence and literacy take time, don’t make for snappy reading or headlines, and don’t shore up political points. Can we stop the train towards right-to-inform laws and make real headway in women’s health? Can we reallocate healthcare dollars towards effective treatments that serve patients and engage them in their care? You have to wonder.

In a unanimous decision, FDA has approved the first breast ultrasound imaging system for dense breast tissue “for use in combination with a standard mammography in women with dense breast tissue who have a negative mammogram and no symptoms of breast cancer.” Patients should not interpret FDA’s approval of the somo-v Automated Breast Ultrasound System as an endorsement of the device as necessarily beneficial for this indication and this will be a thorny concept for many patients to appreciate.
If the approval did not take place in the setting of intense pressure to both inform women that they have dense breasts and lobbying to roll out all sorts of imaging studies quickly, no matter how well they have been studied, it would not be worth posting.
Dense breasts are worrisome to women, especially young women (in their 40s particularly) because they have proved a risk factor for developing breast cancer. Doing ultrasound on every woman with dense breasts, though, who has no symptoms, and a normal mammogram potentially encompasses as many as 40% of women undergoing screening mammography who also have dense breasts, according to the FDA’s press release. Dense breast tissue is most common in young women, specifically women in their forties, and breast density declines with age.
The limitations of mammography in seeing through dense breast tissue have been well known for decades and the search has been on for better imaging studies. Government appointed panels have reviewed the issue and mammography for women in their forties has been controversial. What’s new is the “Are You Dense?” patient movement and legislation to inform women that they have dense breasts.
Merits and pitfalls of device approval
The approval of breast ultrasound hinges on a study of 200 women with dense breast evaluated retrospectively at 13 sites across the United States with mammography and ultrasound. The study showed a statistically significant increase in breast cancer detection when ultrasound was used with mammography.
Approval of a device of this nature (noninvasive, already approved in general, but not for this indication) does not require the company to demonstrate that use of the device reduces morbidity or mortality, or that health benefits outweigh risks.
Eitan Amir, MD, PhD, medical oncologist at Princess Margaret Hospital, Toronto, Canada, said: “It’s really not a policy decision. All this is, is notice that if you want to buy the technology, you can.”
That’s clearly an important point, but not one that patients in the US understand. Patients hear “FDA approval” and assume that means a technology most certainly is for them and a necessary add-on. This disconnect in the FDA medical device approval process and in what patients think it means warrants an overhaul or at the minimum, a clarification for the public.
Materials for FDA submission are available on the FDA website, including the study filed with FDA and a PowerPoint presentation, but lots of luck, finding them quickly. “In the submission by Sunnyvale CA uSystems to FDA, the company stated that screening reduces lymph node positive breast cancer,” noted Amir. “There are few data to support this comment.”
Is cancer detection a sufficient goal?
In the FDA study, more cancers were identified with ultrasound. However, one has to question whether breast cancer detection alone is meaningful in driving use of a technology. In the past year, prostate cancer detection through PSA screening has been attacked because several studies and epidemiologists have found that screening is a poor predictor of who will die from prostate cancer or be bothered by it during their lifetime. We seem to be picking up findings that don’t lead to much to worry about, according to some researchers. Could new imaging studies for breast cancer suffer the same limitation? It is possible.
Another question is whether or not the detected cancers on ultrasound in the FDA study would have been identified shortly thereafter on a routine mammogram. It’s a question that is unclear from the FDA submission, according to Amir.
One of the problems that arises from excess screening is overdiagnosis, overtreatment, and high-cost, unaffordable care. An outcomes analysis of 9,232 women in the US Breast Cancer Surveillance Consortium led by Gretchen L. Gierach, PhD, MPH, at the National Institutes of Health MD, and published online in the August 21 Journal of the National Cancer Institute, revealed: “High mammographic breast density was not associated with risk of death from breast cancer or death from any cause after accounting for other patient and tumor characteristics.” –Gierach et al., 2012
Proposed breast cancer screening tests
Meanwhile, numerous imaging modalities have been proposed as an adjunct to mammography and as potential replacements for mammography. In 2002, proponents of positron emission tomography (PET) asked Medicare to approve pet scans for imaging dense breast tissue, especially in Asian women. The Medicare Coverage Advisory Commission heard testimony, but in the end, Medicare did not approve it for the dense-breast indication.
PET scans are far less popular today, while magnetic resonance imaging (AKA MR, MRI) and imaging have emerged as as adjuncts to mammography for women with certain risk factors. Like ultrasound, the outcomes data is not in the bag for screening with it.
In an interview with Monica Morrow, MD, Chief of Breast Surgery at Memorial Sloan-Kettering Cancer Center, New York, several months ago concerning the rise in legislation to inform women about dense breasts, which frequently leads to additional imaging studies, she said: “There is no good data that women with dense breasts benefit from additional MR screening.” She is not the only investigator to question potentially deleterious use of MR ahead of data collection and analysis. Many breast researchers have expressed fear that women will opt for double mastectomies, based on MR, that in the end, may have been absolutely unnecessary.
“There is one clear indication for MR screening,” stressed Morrow, explaining that women with BRCA mutations should be screened with MRI. “Outside of that group, there was no evidence that screening women with MR was beneficial.”
At just about every breast cancer meeting in the past two years, the benefits and harms of MR and other proposed screening modalities come up, and there is no consensus in the field. It should be noted, though, that plenty of breast physicians are skeptical about broad use of MR– not just generalists outside of the field. In other words, it is not breast and radiology specialists versus the US Preventive Services Task Force – a very important message for patients to understand.
One thing is clear: as these new technologies gain FDA approval, it will be a windfall for industry. If industry is successful and doctors are biased to promoting these tests, many may offer them on the estimated 40% of women with dense breasts who undergo routine mammograms, as well as other women evaluated as having a high lifetime risk. The tests will be offered in a setting of unclear value and uncertain harms. Even though FDA has not approved breast MRI for screening dense breasts, breast MR is being used off label and it is far more costly than mammography.
When patients raise concerns about the unaffordability of medical care, they should be counseled about the uncertain benefit and potential harms of such a test. That may be a tall bill for most Americans to consider: it’s clear that the more is better philosophy is alive and well. Early detection of something, anything, even something dormant, going nowhere, is preferable to skipping a test, and risking who-knows-what, and that is something, most of us cannot imagine at the outset.

Prenatal care and treatment access are big factors.
By Laura Newman
Last week, the media got all excited about the possibility of a cure for HIV perinatal transmission. What was lacking was the recognition that the public remains largely ignorant about HIV in pregnant women. Yet with good wellness care, prevention, HIV testing, and medication,HIV transmission from mother to child can be close to zero. The public needs to know that women who are pregnant and HIV positive can also live good-quality lives, as can their children.
Thanks to Dr. Judy Levison, an obstetrician/gynecologist whose career centers on caring for HIV-pregnant women, I began to learn how scientific advancements in HIV-care make it possible for pregnant women with HIV and HIV-positive men to have children and not transmit the virus to their newborns. In the midst of this learning experience, I found out that a young woman I know, “Angela*,” was HIV positive and wanted to plan a pregnancy. I was shocked; I knew plenty of gay men with HIV, but rarely had I met a woman who had contracted the virus. Planning a pregnancy while being infected with HIV was something that I couldn’t imagine.
“Angela” is married and has lived with HIV for some years, with a low viral load by taking good care of herself and taking recommended antiretroviral therapy, when needed. She sought artificial insemination, one of several options available to HIV-affected couples. It worked. When she was planning her pregnancy, her parents were resistant. They worried that even though she is healthy now, that might change. They couldn’t imagine being saddled with taking care of a young child. Her parents’ resistance reminded me of the old coming-out stories we used to hear and how parents adapted to learning their child is gay. To their credit, both parents soon rose to the occasion. Angela and her spouse have a healthy toddler, and the grandparents love spending time with him.
Angela’s story isn’t everyone’s story. The hubbub at the recent 20th Conference on Retroviruses and Opportunistic Infections was not on the “functional cure” of the baby born to a pregnant woman with HIV, but on why, in this day and age, the mother doesn’t seem to have received the recommended prenatal care and antiretroviral therapy herself. Under what circumstances did she deliver? How did mom and baby get lost in the healthcare system? It’s far too easy to be captivated by a potential breakthrough and forget that plenty of people don’t get access to basic science-backed care that prevents HIV transmission in the first place.
As I describe below and as Angela’s experience illustrates, a lot of evidence shows that it is very safe for women with HIV to get pregnant, have healthy babies, and not transmit HIV to their children. Unfortunately, for many pregnant women with HIV, harsh judgments and inaccurate assumptions often carry the day. Let’s just say that HIV-positive moms and their kids have not earned the acceptance allotted to, say, a Magic Johnson, who has had HIV for decades, and with good HIV and wellness care, lives a good-quality life.
These inroads in science-based HIV prevention and care that have helped Johnson so much lag behind in poor and minority communities in the United States and low-resource countries around the world. HIV disproportionally affects African-Americans in the United States, and access to care, Medicaid cuts, and poverty reduce the chance that many people in need will receive good state-of-the-art prevention (regular testing, practicing safe sex, not sharing drug needles) and wellness care. Perinatal transmission could well rise in these communities.
Facing down ignorance
At first, being pregnant was not easy for Angela — not because her pregnancy was hard (it was not) — but because of the uneasiness some of her coworkers expressed about her becoming pregnant as an HIV-positive woman. Even though Angela worked in healthcare, some of her coworkers thought she had no business being pregnant. When she complained to her supervisor, the manager urged Angela to take it upon herself to educate staff about scientifically proven treatments for pregnant women with HIV that help moms stay well and prevent transmission to the baby. Angela asked instead for an in-service training, which was scheduled. Her colleagues’ attitudes turned around after the in-service.
It meant a lot to her to change the culture.
Angela had a normal term delivery, gave birth to a healthy baby, who is now a toddler, with no sign of HIV infection. Angela’s viral load remains undetectable. They are living healthy, high-quality lives like many other families, moms, and children.
The parents and prenatal planning
The ideal in the setting of HIV infection is that both partners are involved in preconception planning. Prevention of transmission of HIV from an HIV-positive father to an HIV-negative mom and fetus is now possible. The door is now open to HIV-positive men and women who want families but have HIV. Any plans they had to become parents have not simply vanished.
HIV research has advanced to the point that we now know that if HIV-positive individuals work with knowledgeable medical providers and have good access to proven practices, parents and children do quite well. Essential practices include:
Before trying to conceive, people should take antiretroviral drugs and have their infection under control, shown by a low viral load or undetectable levels of the virus (“undetectable” levels vary, depending on the lab) in their blood;
Couples are instructed to have unprotected sex only when the woman is ovulating. Current guidelines recommend using an ovulation prediction kit, which you can purchase at most drugstores.
Artificial insemination is another option that HIV-affected couples are using, as Angela did.
HIV testing is recommended routinely for all pregnant women, as well as for all non-pregnant adults and teens.
If a woman learns during her pregnancy for the first time that she is HIV infected, she can work with her healthcare provider to stay healthy, prevent mother-to-child transmission, and prevent passing HIV to her partner.
In general, people infected with HIV who are not pregnant begin taking anti-HIV medications when their CD4 counts fall below 500 cells/mm3 (HIV targets these immune cells and destroys them, compromising a person’s immunity). The medication regimen during pregnancy depends on whether or not you are taking medication to improve your own health or just your baby’s. In many cases, healthy women delay starting antiretroviral medication until the second trimester, which is when all women should be on HIV medication. However, HIV medication and interactions with other drugs and the fetus are complicated and require consultation with a physician. If women are diagnosed later in a pregnancy, they should start HIV drugs then. You can find detailed recommendations here.
During childbirth, women whose viral loads are still undetectable can have normal vaginal deliveries. However, according to the National Institutes of Health and other authorities, scheduled cesarean delivery at 38 weeks of gestation is recommended to reduce perinatal transmission of HIV for women with HIV-RNA levels >1,000 copies/mL or unknown HIV levels near the time of delivery, regardless of whether they were taking recommended antiretroviral drugs during pregnancy. The guidelines state that when there is a low rate of transmission (viral loads lower than 1000 copies/mL), the benefits of a scheduled c-section are unclear. Dr. Levison, an obstetrician/gynecologist at Baylor College of Medicine, Houston, TX, says that in her practice, women rarely need a cesarean section.
The newborn child
In the United States, breastfeeding is discouraged because HIV can be transmitted in breast milk. According to the Centers for Disease Control and Prevention (CDC), the risk for HIV transmission goes up as much as 45%. However, the topic of breastfeeding remains controversial. In healthy women with no HIV history, the broad consensus is that breastfeeding is best, giving babies excellent nutrition and helping the infant bond with mom. And many parts of the world have problems with sanitation and dirty water, making breastfeeding preferable to mixing formula. Outside of the US, according to Levison, in the UK, breastfeeding guidelines are more liberal. Furthermore, in some cultures, women are afraid not to breastfeed for fear that they will be outed as having an HIV infection, according to Levison, so many treating physicians adapt practice to the culture, preferences of the mom. Internationally, for example, in Africa, women often breastfeed and remain on antiretroviral drugs during that time. Formula is also costly. In the US, poor moms are eligible for formula through the federal Women’s Infants and Children’s nutritional support program.
Besides breastfeeding, HIV-positive moms need to know that pre-chewing of food before feeding baby is a transmission risk.
As soon as a woman goes into labor and during childbirth, the infantmust begin a six-week course of the antiretroviral medication zidovudine (AZT). Current guidelines also state that the baby should be tested for HIV at 14 to 21 days, at 1 to 2 months, and again at 4 to 6 months. If the viral load remains undetectable after two tests, the baby is considered to not have gotten HIV.
Resolving resource disparities
The moms, dads, and kids with HIV have enormous potential to live healthy lives for decades on proven antiretroviral drugs.
In fact, a December 2012 CDC Fact Sheet states that the number of women with HIV giving birth in the United States increased approximately 30% from 6,000 to 7,000 in 2000 to 8700 in 2006. During that same time frame, the estimated number of perinatal infections per year in all 50 states and 5 dependent areas continued to decline.
It’s not all good news, though, because of marked disparities in resource allocation and pre- and perinatal care. According to CDC data, 63% of perinatal infections were in blacks/African-Americans; 22% were in Hispanics/Latinos, and 13% were in whites. That leaves a lot of work to be done in enhancing targeted prevention programs.
Another recent milestone is that the US Preventive Services Task Force is finally about to endorse universal HIV testing, long after the CDC backed such a move in 2006. This milestone is important to because it is also linked to health reform. All public and private health plans are required to provide coverage for U.S. Preventive Services Task Force-recommended preventive services without patient copayments.
With this availability, perhaps women might learn about an HIV infection before they become pregnant, giving them time to have their own treatment in place before it is too late to protect the baby. The case report of the baby cured of HIV gives a lot of hope, but even more preferable would be preventing HIV infection in the first place, through safe sex and not exchanging needles. Once people become infected, for whatever reason, their lives should no longer be viewed as if they are at in a holding pattern until death.
The world needs to know that just like every other mom, dads and pregnant women with HIV can parent children, stay healthy, and not transmit the virus to their babies. Paramount in this is universal HIV testing for adults and teens, prevention programs, and ensuring scientifically proven treatment of the mother before, during, and after her pregnancy.
One of the goals of Double X Science is to raise the profile of women in science. When others are doing this exact same things, we like to let our readers know. Here’s a few recent efforts to expand the public’s knowledge of women scientists:
The Royal Society recently had a wikipedia push for writers to start new and expand the pages of women in science. Having visited wikipedia for writing the Notable Women in Science series, I can say that the number of pages created has definitely expanded and certainly there is much more information provided on a number of women. But there are still gaps. Look for more from Double X Science on this topic in the future.
A group in the UK is making a calendar “to showcase real women doing great science.” Learn more about ScienceGRRL by visiting their website and following thier social media. The images being used in the calendar look to be scenic or portrait-style.
SpotOn provides some tools for the female scientist to promote herself and also provides links that those interested in science might be interested in following, such as twitter lists of women in science.
When researching this post, I found several sites trying to promote women in science. This site provides resources as well as 4000 years of women in science. In addition, they link to many associations dedicated to helping women in science. Geek Feminism has Wednesday Geek Woman posts every Wednesday highlighting women in STEM. The RAISE project has an on-going blog about the issues facing women in science.
Please comment: What is your favorite site working to raise the profile of women in science and why?
