Better Living Through Science: Women in STEM

A look at pioneering women in fields of science, technology, engineering, and mathematics.

In the story we shared earlier this week you learned about Brittany Wegner, a young entrepreneurial scientist who has made breakthroughs in the technology of cancer diagnosis. Continuing in the thread of women in the STEM fields we bring you an in depth look of two women making strides in the fields of astronomy and nuclear non-proliferation, their educational journey, and the impact that women mentors in STEM had on them growing up.


In August of 2014 the Fields Medal, the Nobel Prize equivalent of mathematics, was awarded for the very first time in history to Maryam Mirzakhani, an Iranian woman. Women like Dr. Deidre Hunter, Astronomer and Deputy Director of Science at Lowell Observatory in Flagstaff, Arizona and Dr. Patricia Lewis Research Director for International Security at Chatham House in London are prime examples of women who went against the grain and chose careers that inspired them to change the world. Whether it has been the work of a patriarchal education system, macro cultural conditioning, or a likely combination of the two, when women make up 48% of the U.S. work force and only represent 26% of STEM fields there are still radical shifts to be made.

The importance of modeling careers in STEM to younger women is paramount. “One person who was very influential to me was Vera Rubin,” said Dr. Hunter, “the astronomer who discovered that spiral galaxies rotate. She [Rubin] was passionate about promoting women in science, probably because she had seen so much discrimination during the course of her career. Because of pioneers like that, science is much more open to women today.” Dr. Deidre Hunter has made significant breakthroughs as a scientist and astronomer, researching irregular galaxies, star formation, and star clusters. Hunter grew up during the Apollo Program, and had a fervent desire to become an astronaut. “I thought walking on the moon or another planet would be so exciting,” said Hunter. “I quickly realized that I would never be an astronaut. I wear glasses and in those days astronauts were test pilots and they could not wear glasses. But thinking about it had made me want to know about the universe beyond earth, and I decided I would study what was out there instead.”

Dr. Patricia Lewis, part researcher, part superhero, hybridizes the practice of science with international policy. “I read all the astronomy books in our local library and I used to do science experiments in the kitchen as a young girl,” said Lewis, “[I] was lucky in that I went to an all girls school…my physics and math teachers were all women and we were expected to excel.” “[Now] I run a research department looking at all aspects of international security that ranges from the threat of microbes to the role of gender in international conflicts to nuclear weapons,” noted Lewis. “I am dedicated to doing everything I can to keep people safe from the scourge of war and to make sure that humanity survives this stage in our history.”

Lewis and Hunter’s view is that children need to be encouraged and engaged with STEM topics at an age when they will still be receptive. “I think the key is to get kids (girls and boys) excited about science early on. The 5th-8th grades are a prime time to influence them. It is between the early elementary years when kids are excited about everything and high school when kids lose that spontaneous excitement for the world,” states Hunter. Concurrently, it is integral for the work women have already done in the STEM fields to be recognized. The contribution of women to STEM subjects and professions has never been fully appreciated,” said Lewis. “STEM needs women and women need STEM.”

In addition to their work in the STEM fields, Hunter and Lewis have made teaching and education a fixture in their lives. “Since coming to Lowell Observatory, I co-founded an outreach program that works with teachers and their classes on the Hopi and Navajo Nations,” remarked Hunter. “Each year I partner with 5th-8th grade teachers conducting astronomy activities with their classes. I also hold star parties and bring the classes to Flagstaff to observe on Lowell’s research telescopes.” For Lewis, she has held teaching positions at the University of Birmingham, the University of Auckland New Zealand, the Imperial College, and was the Deputy Director of the Center for Nonproliferation Studies at the Monterey Institute of International Studies.

Clearly mentoring begets mentors as these two women’s past role-models have influenced their careers as scientists, and also their mission to help guide young people to find their path and engage in the worlds of science, technology, engineering, and math—a mission worth pursuing. Young girls like Brittany Wegner who created Cloud4Cancer, a web-based application that has correctly diagnosed 99.11% of 7.6 million cancer trials.

When former Pittsburgh Steelers' center Mike Webster committed suicide in 2002, his death began to raise awareness of the brain damage experienced by NFL football players. A 2017 study found that 99% of deceased NFL players had a degenerative brain disease known as CTE (chronic traumatic encephalopathy). Only one out of 111 former football players had no sign of CTE. It turns out, some of the risks of traumatic brain injury experienced by heavily padded adults playing at a professional level also exist for kids with developing brains playing at a recreational level. The dangers might not be as intense as what the adults go through, but it can have some major life-long consequences.

A new PSA put out by the Concussion Legacy Foundation raises awareness of the dangers of tackle football on developing brains, comparing it to smoking. "Tackle football is like smoking. The younger I start, the longer I am exposed to danger. You wouldn't let me smoke. When should I start tackling?" a child's voice can be heard saying in the PSA as a mother lights up a cigarette for her young son.

On Tuesday morning, President Trump tweeted about some favorable economic numbers, claiming that annual household income is up, unemployment is low, and housing prices are high.

Now, just imagine how much better those numbers would be if the country wasn't mired in an economy-killing trade war with China, bleeding out trillion-dollar-a-year debts, and didn't suffer from chaotic leadership in the Oval Office?

At the end of tweet, came an odd sentence, "Impeach the Pres."

October is domestic violence awareness month and when most people think of domestic violence, they imagine mostly female victims. However, abuse of men happens as well – in both heterosexual and homosexual relationships. But some are taking it upon themselves to change all that.

At this point most reasonable people agree that climate change is a serious problem. And while a lot of good people are working on solutions, and we're all chipping in by using fewer plastic bags, it's also helpful to understand where the leading causes of the issue stem from. The list of 20 leading emitters of carbon dioxide by The Guardian newspaper does just that.

Before the release of "The Joker" there was a glut of stories in the media about the film's potential to incite violence.

The FBI issued a warning, saying the film may inspire violence from a group known as the Clowncels, a subgroup of the involuntarily celibate or Incel community.

Incels an online subculture who believe they are unable to attract a sexual partner. The American nonprofit Southern Poverty Law Center describes them as "part of the online male supremacist ecosystem" that is included in its list of hate groups.
