This View of Life (starts 6:56) In this episode of How on Earth, we talk with David Sloan Wilson, an evolutionary biologist with a special interest in human biocultural evolution. Dr. Wilson is Distinguished Professor of Biology and Anthropology at SUNY Binghamton, and president of the Evolution Institute as well as editor in chief of its online magazine This View of Life. It is not just about biology, these ideas are formed by decades of research and drawing on studies that cover topics from the breeding of hens to the timing of cataract surgeries for infants to the organization of of an automobile plant. Last month he published his latest book, also titled This View of Life to present a comprehensive case for what he calls Completing the Darwinian Revolution.

Healthy Planet+Healthy Humans? (start time: 14:46) 
Dogs have an incredible sense of smell – it’s so good, people can train dogs to sniff our everything from illegal drugs and explosives to lost people and even computer “thumbnail” drives, that maybe someone is trying to sneak into a high security building so they can sneak out information. So how about dogs sniffing for something life-saving, such as a dangerous drop in blood sugars for an insulin-injecting diabetic? For a healthy person, the amount of sugar in the entire bloodstream at anytime is roughly 1 teaspoon. One teaspoon of sugar in around 5 liters of blood. That’s it. For most people, the body’s own insulin production keeps blood sugars in a relatively healthy range, with the pancreas adjusting insulin levels in miniscule amounts to keep blood sugars in balance. For a diabetic who injects insulin, the injection itself can end up putting too much or too little insulin into the body, and this is especially dangerous when it forces blood sugar levels to go far lower than they normally would. Modern technology is reducing the risk, somewhat, through continuous blood glucose monitoring devices. But even these have a lag time, and since sometimes a diabetics blood sugar levels can change dramatically in just 30 minutes, there’s still risk. But now, there are new “blood sugar monitors”. They don’t require batteries. They’re very friendly, they have incredible noses, and they even come equipped with wagging tails. In today’s edition of How on Earth, we talk about “Dogs for Diabetics”.

In 2015, the New Horizons Spacecraft flew past Pluto. Because Pluto is so far away, it took nearly 10 years of travel for the spacecraft to reach that distant dwarf planet — and that was after a decade of work to get the spacecraft to the launch pad. Planetary scientists Alan Stern and David Grinspoon have written a new book, called: “Chasing New Horizons: Inside the Epic First Mission to Pluto”. The book tells the story of developing and operating the New Horizon mission.
