You are more prone to trip when you think someone is watching you. A breakthrough in improving balance as we age might just come through the study of the Achilles tendon. A person gets "falling down drunk" due to a tiny structure in the inner ear that floats when it becomes...

In The Descent of Man Darwin addresses many of the issues raised by his notorious Origin of Species: finding in the traits and instincts of animals the origins of the mental abilities of humans, of language, of our social structures and our moral capacities, he attempts to show that there is no clear dividing line between animals and humans. Most importantly, he accounts for what Victorians called the 'races' of mankind by means of what he calls sexual...

"We all assume we know what life is, but the more scientists learn about the living world -- from protocells to brains, from zygotes to pandemic viruses -- the harder they find it is to locate life's edge"-- What is life?

Zimmer journeys through experiments that have attempted to recreate life; shows how coronaviruses have altered the course of history; and even tries his own had at evolving...

Human beings evolved in a tribal environment. Over the millennia, our brains have become adept at fostering social networks that are the basis of group cohesion, from the primary family unit to the extended associations of clans, villages, cities, and nations. This essential social component of our behavior gave the human species distinct survival advantages in coping with the challenges of an often-hostile environment. This book examines the many...

However, if the destroying begins, then the signs of this are described in what neurologists take to be the symptoms of neurodegenerative diseases. Those most often encountered are Alzheimers and Parkinsons disease, but there are many otherssurprisingly many, as explained here....
