Where Have All the Bees Gone?

Rebecca E. Hirsch (author)

Publisher: Lerner Books ISBN: 9781541583856

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.

Tracking Pythons

Kate Messner (author)

Publisher: Lerner Books ISBN: 9781541583795

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.

Genomics: A Revolution in Health and Disease Discovery

Whitney Stewart, Hans C. Andersson (author)

Publisher: Lerner Books ISBN: 9781728401560

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.
