This engrossing story reveals the facts behind Mary, and young listeners will be on the edges of their seats wondering what happened to her and the innocent typhoid victims.

Vera Rubin was one of the astronomers who discovered and named dark matter, the thing that keeps the universe hanging together. Throughout her career she was never taken seriously as a scientist because she was one of the only female astronomers at that time, but she didn’t let that stop her. She made groundbreaking and incredibly significant discoveries that scientists have only recently been able to really appreciate—and she changed the way that we look at the universe.

The real-life Cinderella story of the very first professional woman astronomer—Caroline Herschel! Comet Chaser is the thrilling biography of a woman who made a lifetime of incredible contributions to science. She was the first woman to discover a comet, the first officially recognized in a scientific role, and the first to be given a Gold Medal by the Royal Astronomical Society.

In 1862, balloons were the only way to reach the sky. But 14-year-old Otto Lilienthal didn’t want to fly in balloons. He wanted to soar like a bird. Scientists, teachers, and news reporters everywhere said flying was impossible. Otto and his brother Gustav desperately wanted to prove them wrong, so they made their own wings and tried to take flight. The brothers quickly crashed, but this was just the beginning for Otto, who would spend the next 30 years of his life sketching, re-sketching, and building gliders.

Emma Lilian Todd's mind was always soaring—she loved to solve problems. Lilian tinkered and fiddled with all sorts of objects, turning dreams into useful inventions. As a child, she took apart and reassembled clocks to figure out how they worked. As an adult, typing up patents at the U.S. Patent Office, Lilian built the inventions in her mind, including many designs for flying machines. However, they all seemed too impractical. Lilian knew she could design one that worked. 

Growing up in the 1920s on a dirt-poor farm in North Dakota, Mary Sherman's life was filled with chores—until she finally began school and discovered she loved to learn. Mary excelled at science, especially chemistry, and leaped at the chance to work in a laboratory during World War II designing rocket fuels. And when the US decided to enter the space race, Mary was chosen over her male colleagues to create the fuel to launch a rocket carrying America's first satellite.

Meg Lowman was always fascinated by the natural world above her head—the colors, the branches, and, most of all, the leaves and mysterious organisms living there. Meg set out to climb up and investigate the rain forest tree canopies—and to be the first scientist to do so. But she encountered challenge after challenge. Male teachers would not let her into their classrooms, the high canopy was difficult to get to, and worst of all, people were logging and clearing the forests. Meg never gave up or gave in. 

Although Orville and Wilbur Wright are celebrated today as heroes for their revolutionary contributions to science and engineering - they are acknowledged as the first men to successfully achieve powered, piloted flight - their success was hard-earned. In fact, it took the self-taught engineers years of work and dozens of crashes before they managed a single 12-second flight! In this first installment of the brand new Epic Fails series, Ben Thompson and Erik Slader take listeners through the Wright brothers' many mishaps and misadventures as they paved the way for modern aviation.

You know the Super Soaker. It's one of the top 20 toys of all time. And it was an accidental discovery that brought it into being. Trying to create a new cooling system for refrigerators and air conditioners, inventor Lonnie Johnson instead created the mechanics for the iconic toy. A love of rockets, robots, and inventions and a mind for creativity were present in Lonnie Johnson's early life.

In 1934, Irene Curie, working with her husband and fellow scientist, Frederic Joliot, made a discovery that would change the world: artificial radioactivity. This breakthrough allowed scientists to modify elements and create new ones by altering the structure of atoms. Curie shared a Nobel Prize with her husband for their work. But when she was nominated to the French Academy of Sciences, the academy denied her admission and voted to disqualify all women from membership.

A boy rides a bicycle down a dusty road. But in his mind, he envisions himself traveling at a speed beyond imagining, on a beam of light. This brilliant mind will one day offer up some of the most revolutionary ideas ever conceived. From a boy endlessly fascinated by the wonders around him, Albert Einstein ultimately grows into a man of genius recognized the world over for profoundly illuminating our understanding of the universe. Jennifer Berne and Vladimir Radunsky invite the reader to travel along with Einstein on a journey full of curiosity, laughter, and scientific discovery. Parents and children alike will appreciate this moving story of the powerful difference imagination can make in any life.

On January 31, 1961, a three-year-old chimpanzee named Ham made history. Strapped inside a Mercury capsule, the little chimp blasted off into the sky, becoming the first intelligent being to ride an American rocket into suborbital space. Ham made a vital contribution to the United States space program. Because there were so many unanswered questions about space travel, scientists could not risk sending humans on a journey into the unknown. Chimpanzees, however, are very similar to humans in the makeup of their skeletons and internal organs.

On April 11, 1970, astronauts Jim Lovell, Fred Haise, and Jack Swigert were launched into space as the crew of Apollo 13. Their mission, like the missions of Apollo 11 and Apollo 12, was to explore the lunar surface. But that mission was never completed. As they began the procedure for landing on the Moon, the spacecraft was rocked by a violent explosion. Oxygen began pouring out of the Service Module, and the spacecraft began to lose power. Jim Lovell radioed Mission Control with the now-famous words, "Houston, we have a problem."

Jacqueline Briggs Martin’s Snowflake Bentley won a Caldecott Medal, a Parents’ Choice Award, and was picked as an ALA Notable Book for Children. Listeners of all ages will cherish this beautiful story about a real man whose discoveries changed the way the world saw snow.

In 1952, April is seven years old and adores her big sister, Annabel. But Annabel is failing her math class and desperately needs help with a tough math problem. April decides to write to Albert Einstein, asking him to give a hand.

Before Carl Linnaeus began classifying organisms, before John James Audubon drew birds from the wild, before Charles Darwin proposed his theory of evolution, there lived a 13-year-old girl named Maria Merian who loved to draw bugs. With no formal training or university education, Maria Merian took on the role of artist, adventurer, and scientist in 17th-century Europe - a time when women were rarely allowed responsibilities outside the home, and unusual interests led to accusations of witchcraft.  

The untold story of five women who fought to compete against men in the high-stakes national air races of the 1920s and 1930s - and won.

Mary Myers always dreamed of flying, but she lived when women were often told to stay put and stay quiet. Determined and fearless, Mary wouldn’t stay tied down. With the help of her husband, she transformed into Carlotta, the famous aeronaut, and took to the skies. Carlotta performed much more than aerial feats in her gas balloons. A skybound scientist, she collected information on currents, weather, and atmospheric pressure.

Formaldehyde, borax, salicylic acid. Today these chemicals are used in embalming fluids, cleaning supplies, and acne medications. But just over a hundred years ago, they were routinely added to all kinds of food by unregulated and unethical companies. Noted science and history writer Gail Jarrow introduces listeners to the relentless work of U.S. government chemist Dr. Harvey Washington Wiley, who mounted a thirty-year campaign to protect consumers from harmful food and drugs. As part of his research, he tested food additives by serving them to a squad of volunteers—the poison eaters.
