After Nora Keegan spent three years studying whether hand dryers hurt children's hearing, she's published her research in a scientific journal.

When she was nine years old, Nora Keegan noticed that many children didn't want to use hand dryers and would often cover their ears around them. She understood from personal experience why they would have this reaction, observing that "sometimes after using hand dryers my ears would start ringing." In the fifth grade, she decided to investigate the topic further for a science fair project and started studying "if they were dangerous to hearing." Three years later, the now 13-year-old Mighty Girl from Calgary, Canada has just published the results of her multi-year study in a scientific paper in the Paediatrics & Child Health, the premiere Canadian pediatric journal. In it, she concludes that "children who say hand dryers 'hurt my ears' are correct" since, as she discovered through her research, many hand dryers operate "at levels that are clearly dangerous to children’s hearing."

Dr. Katie Bouman led the creation of a new algorithm to produce the first-ever image of a black hole.

Scientist Katie Bouman has said that photographing a black hole is "equivalent to taking an image of a grapefruit on the moon, but with a radio telescope." Today, the MIT postdoctoral fellow shared a photo of herself "watching in disbelief as the first image I ever made of a black hole was in the process of being reconstructed." Bouman and her team released this first-ever image of a black hole to the public, which is the first direct visual evidence that black holes exist. Continue reading → Continue reading

"I find that I am bored with anything I understand," says Abel Prize winner Dr. Karen Uhlenbeck.

American mathematician Karen Uhlenbeck has become the first woman to win the Abel Prize — the "Nobel Prize" of mathematics! The 76-year-old professor emeritus of the University of Texas at Austin and visiting scholar at the Institute for Advanced Study in Princeton has made wide-ranging advances in mathematics that influence many sciences, including quantum physics and string theory, and pioneered a new field of mathematics called geometric analysis. "She did things nobody thought about doing, and after she did, she laid the foundations of a branch of mathematics," says Sun-Yung Alice Chang, a Princeton mathematician who sat on the prize committee. Hans Munthe-Kaas, chair of the Abel Committee, added that "her perspective has pervaded the field and led to some of the most dramatic advances in mathematics over the last 40 years."

The Katherine Johnson Independent Verification and Validation Facility is located in the West Virginia native's home state.

"Hidden Figures" mathematician Katherine Johnson played a critical role in NASA's early space program — now, the space agency is honoring her contributions by renaming a NASA software facility after her! The Katherine Johnson Independent Verification and Validation Facility , located in Johnson's home state of West Virginia, is the home of NASA's IV&V Program, which is dedicated to "contributing to the safety and success of NASA’s highest-profile missions" by improving the software used for a variety of space launches and flights. "I am thrilled we are honoring Katherine Johnson in this way as she is a true American icon who overcame incredible obstacles and inspired so many," NASA Administrator Jim Bridenstine said in an announcement. "It’s a fitting tribute to name the facility that carries on her legacy of mission-critical computations in her honor." Continue reading → Continue reading

Dr. Donna Strickland is only the third woman in history to be awarded the Nobel Prize in Physics.

Physicist Donna Strickland has just awarded the 2018 Nobel Prize in Physics for her groundbreaking work studying light and lasers — becoming the third woman in 117 years to win the prestigious award. The 59-year-old associate professor in the Physics and Astronomy Department at the University of Waterloo was a graduate student working on her doctoral dissertation when she and her supervisor invented chirped pulse amplification, a method that creates ultrashort, high-intensity bursts of laser light without destroying amplifiers. The technique is most famous for its use in the development of Lasik eye surgery, but it also allows manufacturers to drill tiny, precise holes and makes it possible to miniaturize laser systems. Strickland, who describes herself as a "laser jock," says that becoming the third woman ever to win a Nobel Prize in Physics is "surreal," adding, "It’s hard for me to take it in right now. But I’m trying to enjoy it." Continue reading → Continue reading

Dr. Frances Arnold, who pioneered the field of "directed evolution," became the fifth woman in history to win the Nobel Prize in Chemistry.

Dr. Frances Arnold has just been awarded the 2018 Nobel Prize in Chemistry for pioneering the field of "directed evolution"  —  becoming the first American woman in history and the fifth woman overall to be honored.  The method she developed of engineering enzymes that mimic the process of natural selection has created a revolutionary new way for scientists and engineers to design more environmentally-friendly industrial processes. It's now being used in laboratories around the world to develop enzymes that can replace toxic compounds in everything from medicines to biofuels to laundry detergents. “My entire career I have been concerned about the damage we are doing to the planet and each other,” she says. “Change is easier when there are good, economically viable alternatives to harmful habits.” Continue reading → Continue reading

For the first time in history, a woman will serve as NASA's chief flight director.

NASA took another giant step for equality this week when it named Holly Ridings as its first female chief flight director! Ridings, who is originally from Amarillo, Texas, will lead the flight directors that oversee human spaceflight missions from Mission Control in Houston's Johnson Space Center.  "Holly has proven herself a leader among a group of highly talented flight directors,” says Director of Flight Operations Brian Kelly. "I know she will excel in this unique and critical leadership position providing direction for the safety and success of human spaceflight missions. She will lead the team during exciting times as they adapt to support future missions with commercial partners and beyond low-Earth orbit." Continue reading → Continue reading

The "Women of NASA" Lego Set has become one of this year's top toys -- now learn the inspiring stories of these trailblazing scientists!

When LEGO released their Women of NASA Building Set last month, it was a sensation. Our Facebook post announcing its release quickly went viral. The set became Amazon's bestselling toy and sold out within a day, showing the strong demand for science toys with female scientists at the forefront!

The set features four pioneering women who made major contributions to the U.S. space program: astronomer and educator Nancy Grace Roman; computer scientist Margaret Hamilton; astronaut and physicist Sally Ride; and astronaut, physician, and engineer Mae Jemison. The 231-piece set, created by LEGO fan and science writer Maia Weinstock, includes minifigures of all four women and buildable models of the Hubble space telescope and a space shuttle.

Weinstock, who first proposed the set on LEGO's crowdsourcing design platform, designed her set to increase awareness of the contributions these women made to the space program and to science as a whole. In her proposal, she wrote: “In many cases, their contributions are unknown or under-appreciated — especially as women have historically struggled to gain acceptance in the fields of science, technology, engineering, and mathematics (STEM)." In a later interview, Weinstock added that she believes it's "critical to have toys that girls can look at and play with and think, ‘that's me!'’ or ‘that could be me!"

The massive popularity of this unique set — the first of its kind since the now discontinued LEGO Research Institute — has generated a sense of excitement and curiosity about the women of America's space program. But while many children and adults may recognize their names, few people know the details of these pioneering scientists' work. In this blog post, we're introducing you to these remarkable women, filling in the details about their careers and why they deserve to hold a special place in space history. We've also recommended books for all ages that let those interested explore their fascinating stories in greater depth. They've been immortalized in LEGO form; now it's time to celebrate the women themselves! Continue reading → Continue reading

A Mighty Girl's top picks of books, toys, and gear to inspire young astronomers -- and introduce them to the women who helped us understand the stars.

On August 21, people across North America will get the chance to witness a once-in-a-lifetime astronomical event: a solar eclipse! It's the first total eclipse in the continental US since 1979, and for central US states, the first total eclipse since 1918. Even for those not in the zone of totality, partial eclipses will be visible in many places. So it's no wonder that there is so much excitement brewing — and with it, a surge of interest in astronomy and all things space!

If the upcoming eclipse has your kids clamoring to learn more about astronomy, this is the perfect time to pursue their interest — and to share stories of the little-known women who have made enormous contributions to the field.
