How On Earth

Wisdom of the Body

Filed under Episodes by Beth Bennett on January 8, 2019 at 7:45 pm {no comments}

Animal scientists have long considered domestic livestock to be too dumb to know how to eat right, but the lifetime research of animal behaviorist Fred Provenza and his colleagues has debunked this myth. Their work shows that when given a choice of natural foods, livestock have an astoundingly refined palate. Like these animals, humans too, have an innate ability to determine what nutrients they need, but we are losing the information from our foods that allow us to make this determination.

A Tale of Two Missions: OSIRIS-REx and New Horizons

Filed under Episodes by Joel Parker on December 25, 2018 at 5:44 pm {no comments}

OSIRIS-REx (starts at 1:00) In today’s first feature, we hear about OSIRIS-REx, NASA’s first mission to do a sample return from an asteroid. Our guest is Dr. Vicky Hamilton, a Staff Scientist at the Southwest Reserarch Institute’s Boulder office, and a member of that mission. She talks about the scientific goals of OSIRIS-REx, and how it plans to obtain and return a sample of the asteroid Bennu.

New Horizons (starts at 14:05) Our second spacey feature is about a mission that you might describe as exploring “beyond the beyond”. The piano-sized, nuclear-powered New Horizons spacecraft flew by Pluto over 3 years ago, and now has its sights set on an even more distant target named Ultima Thule. To talk about that, we have another local scientist from Southwest Research Institute, Dr. Cathy Olkin, Institute Scientist and also a New Horizons mission Deputy Project Scientist. We hear about the flyby events that will take place on New Year’s Eve.

HASEL “Soft Robotic Muscles” lift a Raspberry

Soft Robotic Muscles (WHOLE SHOW) Robotic Materials are going beyond gears and levers toward powerful components that are softer and more muscular. These materials may someday soon help build more human like prosthetic limbs for amputees. . . . or help a harvesting machine pluck ripe strawberries without squishing them. PhD students Nick Kellaris and Shane Mitchell are with CU Boulder’s College of Engineering and Applied Science — Keplinger Lab. They call their soft robotic muscles HASEL actuators. HASEL stands for Hydraulically Amplified Self-healing Electrostatic actuators.

Titan Talk with Sarah Hörst

Filed under Episodes by Joel Parker on December 15, 2018 at 12:00 am {no comments}

Headlines: Inheritance of mitochondrial DNA. Coffee and Parkinson’s disease. Sending your name and a message to the New Horizons spacecraft. Winds on Mars. Water on Asteroids.

Feature: Titan (starts at 8:55) The solar system has so many different worlds that come in all shapes and sizes and histories, from boiling hot Mercury and Venus to icy Pluto and the Kuiper belt. Such extreme alien worlds are exciting, but perhaps the places that catch our imaginations the most are the ones that are more familar – perhaps with the hope of humans one day visiting there and even living there. So we think of places that have atmospheres and have – or once had – liquid water. But then there are those places that live in what you might call “the uncanny valley” between familiar and alien, and perhaps Saturn’s moon Titan fits into that category, with an atmosphere (but not one that you would want to breathe) and lakes (but not ones you would want to swim in).

Our guest today is Titan researcher Dr. Sarah Hörst, an Assistant Professor in the Department of Earth and Planetary Sciences at Johns Hopkins University, where she also is a member of the Hopkins Extreme Materials Institute. She is a Co-Investigator in the proposed Dragonfly mission to Titan. You can also follow her on Twitter as @PlanetDr.

National Assessment on Climate Change

Filed under Episodes by Joel Parker on December 4, 2018 at 10:07 pm {no comments}

Climate Change (starts at 6:30) Volume II of the fourth National Assessment on Climate Change was released on the day after Thanksgiving. The findings are stark. It is already too late to prevent major long term effects of climate change. The scientific community has now turned to predicting and quantifying those effects and how human civilization can respond to mitigate what might be catastrophic results. Today we talk with one of the co-authors of the chapter on Transportation, Professor Paul Chinowksy, of the CU Department of Civil, Environmental and Architectural Engineering. He elaborates on the findings of the report and his frustration at the lack of a serious response by the federal government.

Baking Soda for Autoimmune Disease // Crickets for the Gut

Filed under Episodes by Shelley Schlender on November 27, 2018 at 10:47 am {no comments}

Baking Soda for Autoimmune Disease (starts at 1:00) Georgia Medical College researcher Paul O’Connor reports that a small amount of baking soda in water, for two weeks, shifts the immune cell known as macrophage away from “attack” mode and more toward, “repair” mode. He says this research comes, in part, from studies involving the benefits of baking soda for people whose kidneys are stressed and failing. There’s more research ahead, but O’Connor suspects that someday, these findings might mean that baking soda becomes a safe part of calming down an autoimmune disease attack.

Crickets for the Gut (starts 10:25) New research from Colorado State University reveals that adding just a few teaspoons of cricket powder to a milkshake, or to a muffin, may reduce an inflammatory marker in the blood and increase levels of an intestinal microbe that is known for reducing the chance of a leaky gut that can lead to excess inflammation. The leader of this cricket powder study CSU Department of Food Science and Human Nutrition professor Tiffany Weir.

Nature and Health

Filed under Episodes, Nature Rx by Joel Parker on November 13, 2018 at 2:17 pm {no comments}

Nature is good for you.
It can be a walk in the woods that helps to calm your nervous system and spark novel ideas, or a wilderness retreat that helps to reduce symptoms of PTSD or ADHD. But little is actually understood about how nature offers healing effects. What are the mechanisms? How much nature is enough, and to do what? And how enduring are the effects? “Nature” isn’t only limited to places like Yellowstone or Rocky Mountain National Park. Nature abounds in some cities, as well. City parks, tree-lined neighborhoods, your own garden – these are slices of nature that can have huge benefits to your physical and mental health. However, many cities and neighborhoods that lack a healthy tree canopy, and produce a lot of air pollution from vehicle traffic are plagued by high rates of cardiovascular disease, diabetes and obesity, among other illnesses, among residents. At a time when humans around the globe are migrating to cities at rates never seen before, it is critical that cities increasingly become part of the solution, not just a major culprit behind environmental degradation and human disease.

Today’s show is the first in a series we’ll offer on the connections between nature and human health. It’s called “Nature Rx.”

Our three guests today are working in the nexus between environmental conservation and human health, to make cities part of the solution:

Dr. Ted Smith, director of the Center of Healthy Air, Water and Soil, at the University of Louisville’s Envirome Institute.
Christopher Hawkins, Urban Conservation Program Manager at The Nature Conservancy.
Janette Heung, principal and owner of JWG Global, a management consulting and research think tank in Colorado focusing on environmental conservation and public health.

Read more in the Colorado Outdoor Rx report and the UN Environment Programme report on air pollution.

Living in a World of Thinking Machines

Filed under Episodes by Chip Grandits on October 30, 2018 at 12:42 pm {no comments}

Book Cover: Solomon’s Code by Olaf Groth and Mark Nitzberg, published by Pegasus Books, November 2018

It has been 50 years since the original 2001, A Space Odyssey, where movie viewers first heard Captain Powers asking, “Open the pod bay doors, HAL” and found HAL thought differently about whether that was a good idea. For most of that half-century, artificial intelligence still seemed a long way off, but in the last decode, it has permeated our every day life with unexpected swiftness and thoroughness.

Do we currently live in a world of thinking machines? Is it just around the corner? Far off? Never? And what will that really be like for us humans (I’ll assume for the moment your not a machine reading this…) This is the subject of Solomon’s Code: Humanity in a World of Thinking Machines by Olaf Groth and Mark Nitzberg. With the recent backlash against Facebook, fake news algorithms or headlines about Cambridge Analytica and Russian bots, this book’s release on November 6 could not be more well timed. The book covers economic, social, personal and political implications of living in a world of thinking machines. For this edition of How On Earth, we spoke with co-author Mark Nitzberg, Executive Director of the Center for Human compatible Artificial Intelligence at UC Berkeley and principal at Cambrian.ai. Dr. Nitzberg studied AI at M.I.T. and completed his PhD at Harvard university. His co-author Olaf Groth is Professor of Strategy, Innovation and Economics at Hult International business School, and founder and CEO of Cambrian.ai. The name Cambrian.ai is taken from a metaphor from biological evolution and the Cambrian Geological Period, where most of the major groups of animals first appeared in the fossil record; an event sometimes also known as the “Cambrian Explosion.”

Are we now at a similar point in the evolution of artificial intelligence? Is the metaphor fanciful or very accurate. Chip Grandits talks with Mark Nitzberg co-author of Solomon’s Code to find out what are the forms of AI, if they are different from their progenitors, and whether they really can think.

Front Range Fracking // Planet+Human Health

Filed under Episodes by Susan Moran on October 23, 2018 at 3:26 pm {no comments}

Today’s show offers two features:
Oil & Gas Impacts (start time: 1:05) Proposition 112, which would require oil and gas wells to be at least 2,500 feet from homes, schools, parks and other buildings, has highlighted mounting public concerns about the health, social and other impacts of extensive drilling along Colorado’s Front Range. Weld County is center stage for the latest oil and gas boom; nearly half of Colorado’s 55,000 active wells are located there. Jason Plautz, a Denver-based journalist, discussed with host Susan Moran the science and politics surrounding drilling activities, and whether explosions such as the one in Windsor last December could happen in many other locations. Plautz and Daniel Glick wrote a feature article that has just been published in High Country News.

Healthy Planet+Healthy Humans? (start time: 14:46) Matthew Burgess has been immersed in thinking about and studying how we humans, and the planet we inhabit, can both remain intact—in fact, can both thrive–well into the future. What’s he smok’in, you might ask? In fact, he is a serious environmental scientist at the University of Colorado Boulder. Dr. Burgess and nearly two dozen colleagues authored a recently published scientific paper that applies models to show how we can meet demands of increased populations and economic growth in 2050, while simultaneously achieving bold and effective conservation and climate goals set forth by the United Nations. Dr. Burgess is an assistant professor in Environmental Studies, with an additional appointment in Economics. And he works at the Cooperative Institute for Research in Environmental Science (CIRES), the collaboration between the National Oceanic and Atmospheric Administration (NOAA) and the University of Colorado. He discusses the paper and its implications with hosts Susan Moran and Joel Parker.
