  This book looks at the weird and wonderful world of parasites, the most abundant form of life on Earth. Parasites come in all forms and sizes and inhabit every free-living organism. Parasitism is now, and always has been, a way to survive under changing environmental conditions. From arctic oceans to tropical forests, Scott Gardner, Judy Diamond, and Gabor Racz investigate how parasites survive and evolve, and how they influence and provide stability to ecosystems.Taking listeners to the open ranges of Mongolia, the Sandhills of north-central Nebraska, the Andes of Bolivia, and more, the authors examine the impact parasites have on humans and other animals. Using examples of parasites from throughout the tree of life, the authors describe parasite-host relationships as diverse as those between trematodes and snails and tapeworms and whales. Parasites offer clues to the evolutionary history of particular regions, and they can provide insights into the history of species interactions. Through parasites, biologists can weave together a global knowledge of the past to predict the challenges that we will face in the future.Revealing that parasites are so much more than creepy-crawlies, this book gives up-to-date context for these critical members of the biological diversity of our planet.

  Cryptography is a direct link to the blockchain world. A blockchain is resistant to modification of the data and it is an open distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way. If simply understood it is a growing list of records called blocks. And each block is a cryptographic hash of the previous block, a timestamp and transaction data. Blockchain was invented by a group of people called Satoshi Nakamoto in 2008 to serve as a public transaction of cryptocurrency bitcoin. The identity of that group called Satoshi Nakamoto is still unknown. The invention of blockchain in reference to bitcoin made it the first currency or digital currency to solve the double spending problem without a need of a trusted authority of central server. Blockchain is also considered as a payment rail. There is no security in this chain, so some time computer world marketing also called it snake oil.

  Bitter Pills - The Global War on...

  The explosion of Internet commerce, coupled with globalization and increased pharmaceutical use, has led to an unprecedented vulnerability in the U.S. drug supply. Today, an estimated 80% of our drugs are manufactured overseas, mostly in India and China. Every link along this supply chain offers an opportunity for counterfeiters, and increasingly, they are breaking in. In 2008, fake doses of the blood thinner Heparin killed 81 people worldwide. In 2012, a counterfeit version of the cancer drug Avastin, containing no active chemotherapy ingredient, was widely distributed in the United States. In early 2013, a drug trafficker was sentenced to prison for distributing an assortment of counterfeit, Chinese-made pharmaceuticals across America. By the time he was arrested, he had already sold over 140,000 fake pills to customers.Even when the U.S. system works, consumers are increasingly circumventing the safeguards. Skyrocketing health care costs in the U.S. have forced more Americans to become "medical tourists" seeking drugs, life-saving treatments, and transplants abroad, sometimes in countries with rampant counterfeit drug problems and no FDA. Bitter Pills will heighten the public's awareness about counterfeit drugs, critically examine possible solutions, and help people protect themselves.

  The Gulf of Mexico - A Maritime...

  “[Sledge] rightfully celebrates and affirms the southern sea’s enriching past and gives readers reason to want for its wholesome and meaningful future.” —Jack E. Davis, Pulitzer Prize–winning author of The Gulf: The Making of an American Sea 
   
  The Gulf of Mexico presents a compelling, salt-streaked narrative of the earth’s tenth largest body of water. In this beautifully written and illustrated volume, John S. Sledge explores the people, ships, and cities that have made the Gulf’s human history and culture so rich. Many famous figures who sailed the Gulf’s viridian waters are highlighted, including Ponce de León, Robert Cavelier de La Salle, Francis Drake, Elizabeth Agassiz, Ernest Hemingway, and Charles Dwight Sigsbee at the helm of the doomed Maine.  
   
  Gulf events of global historical importance are detailed, such as the only defeat of armed and armored steamships by wooden sailing vessels, the first accurate deep-sea survey and bathymetric map of any ocean basin, the development of shipping containers by a former truck driver frustrated with antiquated loading practices, and the worst environmental disaster in American annals. 
   
  Occasionally shifting focus ashore, Sledge explains how people representing a gumbo of ethnicities built some of the world’s most exotic cities—Havana, way station for conquistadores and treasure-filled galleons; New Orleans, the Big Easy, famous for its beautiful French Quarter, Mardi Gras, and relaxed morals; and oft-besieged Veracruz, Mexico’s oldest city, founded in 1519 by Hernán Cortés.  
   
  In the modern era the Gulf has become critical to energy production, fisheries, tourism, and international trade, even as it is threatened by pollution and climate change. The Gulf of Mexico is a work of verve and sweep that illuminates both the risks of life on the water and the riches that come from its bounty.
