Carried by mosquitoes, the Zika virus is spreading quickly through many countries in South America and the Caribbean. We report on the history of the virus, its dangers, why the World Health Organization has said it is global health emergency, and what Brazil plans to do to stop it. Money is being spent to make access to the 'world's oldest temple' in Turkey easier. We outline why the site raises so many unanswered questions. Elsewhere, the secretary birds' stamp is measured with some surprising results and the Doomsday Clock remains at three minutes to midnight.
Margaret Atwood is acknowledged as one of the foremost writers of our time. In Moral Disorder, she has created a series of interconnected stories that trace the course of a life and also the lives intertwined with it—those of parents, of siblings, of children, of friends, of enemies, of teachers, and even of animals. As in a photograph album, time is measured in sharp, clearly observed moments. The ’30s, the ’40s, the ’50s, the ’60s, the ’70s, the ’80s, the ’90s, and the present —all are here. The settings vary: large cities, suburbs, farms, northern forests.
Why Pi?, the entertaining follow-up to the popular Go Figure!, presents even more mind-bending ways to think about numbers. This time, author Johnny Ball focuses on how people have used numbers to measure things through the ages, from the ways the ancient Egyptians measured the pyramids to how modern scientists measure time and space. Why Pi? includes games, puzzles, brainteasers, and fun facts, plus answer key.
