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.
Burmese pythons are native to Southeast Asia, so when one showed up dead along the side of a Florida highway in 1979, scientists wondered where it came from. No one knew the snakes had launched a full-scale invasion. Pet pythons that escaped or were released by their owners started breeding in the wild, and these enormous predators began eating every animal in their path. Today a group of scientists at the Conservancy of Southwest Florida is tracking Burmese pythons to find ways to stop their spread. Page Plus links lead to video clips and photos of the scientists working in the field. Delve into the science of pythons and their role as invasive predators.
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.
Albert Einstein's restless intelligence drove him to ponder the biggest topics the universe has to offer: light, time, mass, energy, and more. His conclusions changed the way people thought about the laws of physics. But first, he had to pass his university entrance exams. This graphic biography traces Einstein's path from his home country of Germany to his studies in Switzerland to his time in the United States. It also follows his life as an international scientific celebrity and his refusal to stay silent in the face of anti-Semitism.

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.
Bitcoin is a digital currency—money that exists only online. Some people have used it to get rich. Others have accidentally lost it forever. Learn what decides bitcoin's value and how anyone with a fast computer can mine it. You'll also explore blockchains, the technology used to make bitcoin transactions. See how the blockchains may change the internet forever.
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
