Showing results for "life-" in History

In 1920, at the end of the last major pandemic, global life expectancy was just over 40 years. Today, in many parts of the world, human beings can expect to live more than 80 years. As a species, we have doubled our life expectancy in just one century. There are few measures of human progress more astonishing than this increased longevity.

The explorers featured in this volume include: Michele Dougherty, the mathematician who persuaded the Cassini mission to Saturn to make a diversion; Richard Fortey on his love of trilobites; Monica Grady, Meteorite Lady; neurosurgeon Henry Marsh on slicing through our thoughts; the Director of the British Antarctic Survey, Jane Francis; Jocelyn Bell Burnell describing how she missed out on a Nobel Prize; Brian Cox on quantum mechanics; and Nobel Prize winner John Sulston on why he thought it would be a good idea to sequence the human genome.

How did life begin? Why are we here? These are some of the most profound questions we can ask. For almost a century, a small band of eccentric scientists has struggled to answer these questions and explain one of the greatest mysteries of all: how and why life began on Earth. There are many different proposals and each idea has attracted passionate believers who promote it with an almost religious fervour, as well as detractors who reject it with equal passion.

Why cracking the code of human conception took centuries of wild theories, misogynist blunders, and ludicrous mistakes.Throughout most of human history, babies were surprises. People knew the basics: Men and women had sex, and sometimes babies followed. But beyond that the origins of life were a colossal mystery. The Seeds of Life is the remarkable and rollicking story of how a series of blundering geniuses and brilliant amateurs struggled for two centuries to discover where, exactly, babies come from.

Does life exist on Mars? The question has captivated humans for centuries, but today it has taken on new urgency. NASA plans to send astronauts to Mars orbit by the 2030s. SpaceX wants to go by 2024, while Mars One wants to land a permanent settlement there in 2032. As we gear up for missions like these, we have a responsibility to think deeply about what kinds of life may already inhabit the planet - and whether we have the right to invite ourselves in.

It seems likely that scientists will someday discover how life can emerge on habitable planets like the early Earth and Mars. In Origin of Life: What Everyone Needs to Know, David W. Deamer has written a comprehensive guide to the origin of life that is organized in three sections.

Daily we overlook fundamental simplicities. There are some fascinating things about how things got so easy. This book explores some interesting and captivating history behind everyday things that simplify our lives immensely. Why is your keyboard QWERTY? Why do we have 24 hours in a day and 12 months in a year? To highlight the importance of these simplicities, the book contrasts the daily lives of people who live in Anarcha, where there is no agreed-upon clock, calendar, unit of measurement, et cetera.
