"You are to report to Station X at Bletchley Park, Buckinghamshire, in four days time....That is all you need to know." This was the terse telegram hundreds of young women throughout the British Isles received in the spring of 1941, as World War II raged. As they arrived at Station X, a sprawling mansion in a state of disrepair surrounded by Spartan-looking huts with little chimneys coughing out thick smoke―these young people had no idea what kind of work they were stepping into. Who had recommended them? Why had they been chosen? Most would never learn all the answers to these questions.

Bletchley Park was a well-kept secret during World War II, operating under the code name Station X. The critical work of code-cracking Nazi missives that went on behind its closed doors could determine a victory or loss against Hitler’s army. Amidst the brilliant cryptographers, flamboyant debutantes, and absent-minded professors working there, it was teenaged girls who kept Station X running. Some could do advanced math, while others spoke a second language. They ran the unwieldy bombe machines, made sense of wireless sound waves, and sorted the decoded messages. They were expected to excel in their fields and most importantly: know how to keep a secret."

"Space probes, self-assembling robots, crash-absorbing cars, and designer proteins all have one thing in common: their use of folding technologies. To develop these technologies, engineers are taking inspiration from an unusual source―origami, the ancient art of paper folding. Examine origami's origins, how it intersects with mathematics, and how it became a tool to solve some of the most complicated challenges in engineering, architecture, technology, and medicine today. Plus, get a close-up look at these technologies with two augmented reality images included in the book!"

"The cold, dark world that lies at the farthest reaches of our solar system holds a vast collection of secrets, and for most of human history, we had no idea anything was out there. But, driven by curiosity and equipped with new technology, astronomers have determined that beyond the orbit of Neptune are countless icy comets, strange particles that dance under the influence of the sun, and signs of undiscovered planets. To learn more about these far-flung objects, scientists have finally begun to explore the distant solar system, finding answers to age-old questions at the same time that they encounter new mysteries.

With Ron Miller’s incredible illustrations and photographs from NASA probes and telescopes, The Big Backyard takes us on a tour through the solar system’s most obscure neighborhoods and into its darkest corners, to places beyond the limits of the human eye. Miller expertly describes the formation of the solar system and the history of the exploration of the outer solar system before delving into the latest discoveries and missions. Read on to learn what sorts of objects orbit at such extreme distances, what happens at the boundary between the sun’s influence and interstellar space, whether there is such a thing as the mysterious Planet X, and how life on Earth could not exist without the happenings at the edge of the solar system."

"CRISPR stands for clustered regularly interspaced short palindromic repeats. If it sounds complicated, it is—but it’s also one of the most powerful ways we can shape the future. And it’s poised to completely upend the way we think about science.

Author Yolanda Ridge tackles this topic in a friendly and accessible tone, with two introductory chapters covering the basics of DNA and genetic modification before taking readers through the ways that this ground-breaking science could affect them by potentially:

• eliminating diseases like malaria and cancer,  

• improving the stability of our food supply, and

• helping to manage conservation efforts for threatened animals and environments.

 But all of these possible advancements come with risks, the biggest being that the consequences are unknown. Chapters end with “Stop, Go, Yield” sections encouraging readers to consider the pros and cons of using CRISPR. “Cutting Questions” give readers the opportunity to further reflect on the ethics of the science.

CRISPR is a game changer. This important book, with detailed scientific illustrations, brings much needed clarity to a topic that will affect readers for generations to come."

"Believe it or not, ice isn’t always just frozen water.

In fact, most of the ice covering our planet contains thousands of years' worth of information about our atmosphere. This ice is made up of a lot more than snow—it has soot, volcanic ash, gasses, and other substances that affect the climate. And if we drill a piece of that ice? We get a frozen time capsule, courtesy of Earth.

In this exhilarating middle grade nonfiction book by a former educator, kids are immersed in the field of paleoclimatology. Readers go along on an ice core expedition, run through each step in the collecting and transporting process, review the fascinating components of an ice core, and explore the specialized labs where scientists examine them.

But these pieces of our planet are more than just cool records. By preserving and studying these frosty collections of climate history, we can learn from previous patterns and better protect our planet in the future. The final chapter focuses on ice as a key tool in the fight against climate change."
