In the United States, racial profiling affects thousands of Americans every day. Both individuals and institutions―such as law enforcement agencies, government bodies, and schools―routinely use race or ethnicity as grounds for suspecting someone of an offense. The high-profile deaths of unarmed people of color at the hands of police officers have brought renewed national attention to racial profiling and have inspired grassroots activism from groups such as Black Lives Matter. Combining rigorous research with powerful personal stories, this insightful title explores the history, the many manifestations, and the consequences of this form of social injustice.

"I didn't hear the word transgender until I was eighteen, when a person I was dating came out as trans. My boyfriend came out as my girlfriend, and I thought, 'What . . . is that?' She said, 'I just don't think I'm a man.' And I said, 'Guess what? Neither do I.' And then the skies parted, and I understood who I was."―Katie Burgess, nonprofit director and community activist/organizer Meet Katie, Hayden, Dean, Brooke, David, Julia, and Natasha. Each is transgender, and in this book, they share their personal stories. Through their narratives, you'll get to know and love each person for their humor, intelligence, perseverance, and passion. You'll learn how they each came to better understand, accept, and express their gender identities, and you'll follow them through the sorrows and successes of their personal journeys. Transgender Lives helps you understand what it means to be transgender in America while learning more about transgender history, the broad spectrum of transgender identities, and the transition process. You'll explore the challenges transgender Americans face, including discrimination, prejudice, bullying and violence, unequal access to medical care, and limited legal protections. For transgender readers, these stories offer support and encouragement. Transgender Lives is a space for trans* voices to be heard and to express the complexities of gender while focusing on what it means to be human.

And through Tillie’s own words, the story of one of the Civil War’s most famous battles comes alive.

"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.

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?

Gandhi's Salt March united all Indians in peaceful protest for independence. Yet British forces met them with violence and imprisonment. In this story of India's struggle for freedom, we'll learn how Gandhi’s philosophy of nonviolent action overpowered the British government. And we'll witness how Gandhi's actions influenced civil rights movements around the world. "With this salt, I am rocking the foundations of an Empire."―Mohandas Gandhi, 1930 On April 6, 1930, Mohandas Gandhi stood on the coast of the Arabian Sea in western India. He and his followers had walked 241 miles (388 kilometers) to reach this place. Now, at the end of their long journey, Gandhi made a simple gesture marking the beginning of a revolution: he reached down, grabbed a clump of sea salt, and raised it overhead. This signaled to all Indians to embark on a course of civil disobedience―making and selling their own salt. At this time, India had been ruled by the British Empire for more than 200 years. The British had taken control of India's main industries, including its highly profitable salt manufacturing process. By law, Indians were not allowed to produce their own salt―or to even pick up a lump of sea salt. Everyone in India, no matter how poor, paid a salt tax to the British government.

In the twenty-first century, because of climate change and other human activities, many animal species have become extinct, and many others are at risk of extinction. Once they are gone, we cannot bring them back—or can we?With techniques such as cloning, scientists want to reverse extinction and return lost species to the wild. Some scientists want to create clones of recently extinct animals, while others want to make new hybrid animals.Many people are opposed to de-extinction. Some critics say that the work diverts attention from efforts to save species that are endangered. Others say that de-extinction amounts to scientists "playing God." Explore the pros and cons of de-extinction and the cutting-edge science that makes it possible.

- A stolen top-secret nuclear reactor- A young lawyer falsely accused of murder- A government project to build a quantum supercomputer- A secretive consultancy that can fix any problemAll connected by invisible strings, but who are the puppets and who is the puppeteer?When someone steals a top secret experimental nuclear reactor, the British intelligence services have no leads. Their hopes rest on a new quantum super computer, one capable of interpreting patterns in the oceans of intelligence data. There’s just the small challenge of building it.Gregory Jenson, CEO of ZAT Systems, is tasked by MI5 to create the computer, but ghosts in his past could thwart matters before he even begins. Young lawyer, Michael Adams, is given the task of helping Jenson, but he soon has problems of his own.And they’ll soon learn that a hidden player wants to use the new system for their own plans – someone incredibly well-informed, and prepared to go to any lengths to achieve their goals.And if they succeed, the recovery of the nuclear reactor will be the least of everyone’s problems.

On a hot day in the African savannah, a group of elephants searches for food. While foraging they often lose sight of one another. Yet at the end of the day, in one coordinated movement, the elephants suddenly regroup. This coordinated movement—and others like it—has puzzled scientists and caused them to question how elephants communicate with each other.Since the 1990s, scientists have gathered significant data on elephant “talk.” Biologists have determined that elephants use a complex system of communication of at least ten distinct sounds, combined in many variations. Researchers are now asking: what do these sounds mean?As scientists study the elephant sounds that humans can hear, they are also identifying ways elephants communicate through nonverbal behaviors and making sounds too low for human ears. Scientists have realized that elephants even receive messages by using their sensitive feet to feel vibrations in the ground. All of these discoveries are helping elephant researchers better understand elephant behavior. But the elephant’s time as a wild animal is running out. Threatened by habitat loss and illegally hunted for their ivory tusks, elephants are on the brink of extinction. Will understanding elephant talk be the key to saving the species?

What would you have worn if you lived in the Old West? It depends on who you were! For example, Native Americans made clothing from rabbit fur, deerskins, buffalo hides, and plant fibers. They decorated their clothing with beads, porcupine quills, fringe, and feathers. However, cowboy gear included leather chaps, boots, and bandanas. Cowboys used their tall, wide-brimmed hats for protection from sun and rain and sometimes to carry water. Read more about fashions of the Old West―from buckskins to sunbonnets to sombreros―in this fascinating book!
