Baking Soda for Autoimmune Disease // Crickets for the Gut

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

Nature Rx (start time: 9:33): Nature is good for your health. Sounds obvious, but what does science tell us? A walk in the woods can help to calm your nervous system and spark novel ideas, and spending time in nature can reduce symptoms of PTSD or ADHD. Little is actually known about how nature offers healing effects. How much nature is enough, and to do what, exactly? 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 improve your physical and mental well-being. Researchers are measuring the effect of living near trees, for instance, on cardiovascular disease, diabetes and obesity. 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

solomonscodebookimg — 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.

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.

Boulder researchers have discovered a key mechanism by which skin begins to develop in embryos, shedding light on the genetic roots of birth defects like cleft palate and paving the way for development of more functional skin grafts for burn victims. We bring you an interview with lead researchers, Associate Professor Rui Yi of CU Department of Molecular, Cellular and Development Biology, who explains some of the secrets he has been uncovering about “How Skin Begins” [3:27]

How do you reconcile a flair for competition and performance with a penchant for science and learning. We’ll hear from Doctor Daniel Rudnicki, who’s first career was as a competitive and professional figure skater, then after getting an undergraduate degree in Biochemistry and PhD in Organic Chemistry from CU he then founded a biotech company. But still needing an outlet for his urge to perform he has created the persona of Doctor Dan to bring enthralling and flashy science presentations to local schools. [19:08]

Late-summer Cricket Chorus (start time: 1:02) One of the most poetic sounds of the end of summer is …. no, not your kids kicking and screaming because summer is over. It’s the sound of crickets, katydids and other melodic insects “chirping” at night. Our focus here is Snowy Tree Crickets in Colorado. They are called “temperature” crickets because you can calculate what the temperature is outside based on how many times these crickets “chirp” in a certain time period. How On Earth’s Shelley Schlender took a stroll recently with two Boulder naturalists — Steve Jones and Scott Severs — to learn more about how, and why, crickets in general make their chirping sound, and why we hear so many of them in the evenings this time of year. Some resources about crickets and their brethren: 1) http://songsofinsects.com/ 2) biology and recordings of nearly all singing Orthopterans (crickets, grasshoppers, katydids), at Singing Insects of North America (SINA) http://entnemdept.ufl.edu/Walker/buzz/.

The Science of Aspen (and other) Foliage (starts: 9:40) One of the most iconic images of Colorado is aspen groves quaking in early fall in their brilliant yellow, orange and even red hues. This year, the aspen, and many other plants, are changing colors earlier than normal. Due largely to the extended warm and dry conditions, many aspen leaves are fading and shriveling without turning bright colors. Dr. Jeff Mitton, an evolutionary biologist and a professor emeritus at the University of Colorado Boulder, talks with host Susan Moran about what dictates the timing and intensity of foliage. Dr. Mitton also writes a bimonthly column, called Natural Selections, in the Daily Camera. Here’s one (of many) on crickets.
