How On Earth

Electric Car Road Trips // Renewable Energy Nation . . . in 15 Years

Tesla Superchargers - Rural Arizona — Tesla Superchargers – Rural Arizona

Electric Car Road Trips (starts 3:42): We go on a road trip with How on Earth’s Shelley Schlender to see how all-electric vehicles are exceeding “range anxiety” by driving coast to coast, all on electricity. Along the way we talk with Boulder Nissan’s Nigel Zeid about regional plans to help more drivers “plug in” and with Hunter Lovins, head of Natural Capitalism Solutions.

Renewable Energy Nation (starts 11:53): Joel Parker talks live with NOAA scientist Alexander MacDonald and Christopher Clack, a mathematician at the University of Colorado-Boulder. They have developed a model that demonstrates how the entire U.S. can run on solar and wind power–with existing technologies, with no batteries, and at lower cost than today’s prices–within 15 years. For more information, see this video and these animations of:

Using the Microbiome to Determine Time of Death

Using the Microbiome to Determine Time of Death (starts at 5:40): This week on How on Earth, we speak with Jessica Metcalf, an evolutionary biologist, who studies bacteria, specifically the microbiome. One of her research interests is using molecular biology to address basic hypotheses about the role of microbes in corpse decomposition. The time since death, or postmortem interval, also known as (PMI), is important for criminal investigations because it can lead to the identification of the deceased and validate alibis. PMI is critical to both forensic science and pop culture (e.g. TV shows Bones, CSI). Recently she co-authored a paper published in Science, describing how various species of the microbiome can be used to accurately and repeatedly determine the post-mortem interval.

Hubble Space Telescope

Today’s show of How on Earth starts with headlines about dark matter, genetic mysteries, jealous monkeys, and polar bears. We then present a short feature of BBC’s Science in Action about the Hubble Space Telescope.

This is shorter than our usual How on Earth show due to technical difficulties with the phone system for our feature interview with entomologist Jonathan Lundgren; that feature will appear in a future show.

Our Microbes, Ourselves — Special Call-in Show

Our Microbes, Ourselves, Dec. 31, 2015: Roughly one hundred trillion bacteria are living, and gorging, in our gut–all the more so during the indulgent holidays. Microbes influence our health and well-being, by affecting our gut directly, as well as the crops we eat and the soils in which we grow crops. These microbial communities – called the gut microbiome — have been linked to many disorders, including obesity, inflammatory bowel disease, diabetes, cancer, immune disorders, and even mental illness. We are just at the dawn of a new era of microbial treatments for many illnesses. After a recent How On Earth show generated so much interest, we decided to bring our guest, Amy Sheflin, back for an hour-long call-in show on A Public Affair on KGNU. Amy is a doctoral student at Colorado State University in food science and human nutrition. She studies how the food we eat alters the microbial communities in our gut, and how those microbes in our bodies influence our overall health. For more info on the gut microbiome, check out Amy’s favorite books on the topic: The Good Gut, by Justin and Erica Sonnenburg; and The Inside Tract, by Gerard Mullins. Also check out the American Gut Project.

Hunter Lovins – Regenerative Economics for the Future of Humanity

Hunter Lovins - Natural Capitalism Solutions — Hunter Lovins – Natural Capitalism Solutions

Hunter Lovins – Regenerative Economics (Starts 2:42) One of the world’s leading voices for the environment is urging the world to work for even more than a sustainable economy. She says it’s time for a regenerative economy. That’s the message from Boulder County resident, Hunter Lovins. Lovins heads up Natural Capitalism Solutions, and she’s a sought after speaker around the world, as well as here in Colorado. To give you an idea about what the vision of Lovins for a regenerative economy, here is an excerpt from a recent talk about the Future of Humanity. This talk was recorded in Boulder as part of the Colorado Chautauqua Events series, in conjunction with the Boulder City Club.

Climate Change and Cities

Climate Change and Cities (starts at 5:05) Sea level rise, severe storms, heat waves – these are just a few of the challenges cities might be facing as the climate changes in the next few decades. So how should they adapt to cope with such events? And with urban developments being one of the largest contributors to greenhouse gas emissions, what can they do to mitigate their impact?

These are questions that the Urban Climate Change Research Network has set out to address in its Second Assessment Report on Climate Change and Cities. The report gives the expected climate projections for 100 cities along with guidance on increasing resilience and reducing impact. The Network released its summary for city leaders at the Paris talks only three weeks ago, and Boulder’s Paty Romero Lankao was there to promote the report — she was a co-editor of the report and coordinating lead author of the chapter on governance. Dr. Lankao is a research scientist at the National Center for Atmospheric Research who investigates the interactions between urban development and global environmental change, and in our show she talks with us about the outlook for cities and the report.

Grad School Science

What is graduate school and how does it differ from the undergraduate experience? What drives people to go through another 4…5…6…or more years of school? Today’s show features some people who might be able to tell us about the grad school experience in the sciences. We have three grad students from the University of Colorado at Boulder:
* Joe Villanueva in the Molecular Cellular and Developmental Biology department.
* Annie Miller, in the Integrative Physiology department.
* Marcus Piquette, in the Astrophysical and Planetary Science department.
Each of them works in a lab with an advisor and is doing projects that will eventually lead to a thesis and getting a PhD, and they talk about what they do and what grad school is like.

CUCafe // Math, Science, Intuition and CFS

Today we had a terrific show with two local guests. First, Sarah McQuate, Post-Doc at the University of Colorado joins us to talk about CUCafe, a student run group committed to creating dialogues and safe spaces for underrepresented student on campus. We talk about their role in the most recent Inclusion and Diversity Summit on campus along with their on-going efforts and events.

cucafeseminar.wordpress.com

Next, Julie Rehmeyer, a award-winning science tells us about her experience as a math graduate student at MIT and her investigative research into Chronic Fatigue Syndrome. These two stories form interesting connections as we discuss the meaning of intuition; a skill that is acknowledge as powerful in the mathematics community but not necessarily cultivated or nourished. Additionally, Julie finds resilient solutions using her analytical and intuitive skills when enduring a incapacitating experience with Chronic Fatigue Syndrome, treatment for which is scarce and poorly understood in the scientific community.

HERE is here latest article on the research of CFS
