"Houston, we've had a problem." On April 13, 1970, the three astronauts aboard the Apollo 13 spacecraft were headed to the moon when a sudden explosion rocked the ship. Oxygen levels began depleting rapidly. Electrical power began to fail. Astronauts James Lovell, Jack Swigert, and Fred Haise were about to be stranded in the inky void of outer space. The mission to the moon was scrapped. Now, Apollo 13's only goal was to bring the crew home. With the damaged spacecraft hurtling towards the moon at roughly six thousand miles per hour, there was little hope of success. But the astronauts and mission control were fully prepared to do whatever it took to return the crew to Earth. This space disaster occurred at the peak of the United States' Space Race against the Soviet Union. But for four days in 1970, the two nations put aside their differences, and the entire world watched the skies, hoping and praying the astronauts would return safely. As missions to Mars and commercial space flight become a reality, the time is now to be reminded of our common humanity, of how rivals can work together and support each other towards a shared goal. Because no matter what happens or where we travel, we all call Earth home.
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!
Apples, blueberries, peppers, cucumbers, coffee, and vanilla. Do you like to eat and drink? Then you might want to thank a bee. Bees pollinate 75 percent of the fruits, vegetables, and nuts grown in the United States. Around the world, bees pollinate $24 billion worth of crops each year. Without bees, humans would face a drastically reduced diet. We need bees to grow the foods that keep us healthy. But numbers of bees are falling, and that has scientists alarmed. What's causing the decline? Diseases, pesticides, climate change, and loss of habitat are all threatening bee populations. Some bee species teeter on the brink of extinction. Learn about the many bee species on Earth—their nests, their colonies, their life cycles, and their vital connection to flowering plants. Most importantly, find out how you can help these important pollinators.
Over the past 50 years, scientists have made incredible progress in the application of genetic research to human health care and disease treatment. Innovative tools and techniques, including gene therapy and CRISPR-Cas9 editing, can treat inherited disorders that were previously untreatable, or prevent them from happening in the first place. You can take a DNA test to learn where your ancestors are from. Police officers can use genetic evidence to identify criminals—or innocents. And some doctors are using new medical techniques for unprecedented procedures. Genomics: A Revolution in Health and Disease Discovery delves into the history, science, and ethics behind recent breakthroughs in genetic research. Authors Whitney Stewart and Hans Andersson, MD, present fascinating case studies that show how real people have benefitted from genetic research. Though the genome remains full of mysteries, researchers and doctors are working hard to uncover its secrets and find the best ways to treat patients and cure diseases. The discoveries to come will inform how we target disease treatment, how we understand our health, and how we define our very identities.
Containing 97 percent of Earth's water supply, the ocean plays a huge role in regulating global temperatures, supporting plant and animal life, and contributing to the livelihoods of millions of people. But in spite of all this, the ocean remains drastically unexplored, and the details of its impact on human lives aren't fully understood. Scientists from around the world are realizing that to address issues plaguing the ocean, such as dead zones, coral bleaching, and climate change, we need to better understand this incredible, unique feature of our planet. With a range of impressive, cutting-edge technologies at their disposal, oceanographers have set out to measure, sample, and analyze at every turn. Every day, mysteries about the ocean are being solved, and every day, new questions come to light. The more scientists learn, the better they are able to answer these new questions. What lies in the deep? And who is at the forefront of these exciting discoveries? The scientists and research included in this book shed light on the most pressing issues currently facing oceanographers and point us in the right direction to solving these challenges.
In January 2009, a mysterious software developer, Satoshi Nakamoto, exchanged a specially designed code with another developer. The code was a digital currency that Nakamoto had proposed several months before in a paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System.” This was the first Bitcoin transaction. Since then, Bitcoin has become the face of a tech revolution in digital cryptocurrencies based on blockchain technology. Its success has sparked a tech revolution that could fundamentally change global economics. Delve into the world of coders, libertarians, criminals, financial regulators, and crypto-detectives to understand what digital cryptocurrencies have to offer, their limitations and potential pitfalls, security issues, and how they may affect government and financial regulations in the future.
On April 22, 1970, an estimated twenty million people held in a teach-in to show their support for environmental protections. This new celebration, Earth Day, brought together previously fragmented issues under the same banner. It was the largest nationwide event ever, and lawmakers took notice. But one day didn't change everything. Fifty years after the first Earth Day, climate change remains a dire concern. The divide between political parties continues to widen, and environmental policy has become an increasingly partisan issue. The spread of disinformation has also made climate change a debatable idea, rather than scientific fact. A new generation of advocates continue the fight to make environmental policy a top priority for the United States and for nations around the globe
The best part about coding is that anyone with a computer can learn how to do it. From education to healthcare to entertainment, software touches almost every aspect of twenty-first century life. Take a high-level perspective on the types of people who create that software—including many jobs that do not involve writing code at all. Learn about the software development cycle and the huge variety of skills developers draw on, including psychology, mathematics, and art, to create amazing apps and programs. Explore why diversity is needed to prevent bias in design. Learn about the different coding languages and what they are used for, how developers choose a language, and tools that simplify coding. Jennifer Connor-Smith breaks down stereotypes about coding as a career that is open only to technology-obsessed gamers, revealing ways people use software to improve medical care, nurture dementia patients, promote social justice, and more. Hands-on activities show you how easy it is to learn to think like a coder. The next generation of coders will require diverse teams, creativity, and ethical codes of conduct to create the best and most successful software. Will you be one of them?
