Science of Deathbed Visions Apr 16, 2024
Show notes

Dr. Christopher Kerr

The Science of Deathbed Visions Many people have visions and dreams as they near the end of their life in which they reunite with loved ones who have gone before them. What can science tell us about these mysterious and common experiences? And how do they affect those who have them? These are questions that Chris Kerr, a hospice physician and neurobiologist, set out to answer through research decades after he witnessed his dying father having one when Kerr was an adolescent. Dr. Kerr, is the Chief Medical Officer and Chief Executive Officer of Hospice & Palliative Care Buffalo. He was featured in a recent New York Times magazine article . He is also the author of the book Death is But a Dream: Finding Hope and Meaning in End-of-Life Dreams.

Corban Tillemann Dick c Mabell Quantum — Colorado – The Quantum State Apr 09, 2024
Show notes

Corban Tillemann Dick c Maybell Quantum

Colorado – The Quantum State: We speak with Corban Tillemann-Dick about how Colorado has emerged as a world leader in Quantum Technologies. Tillemann-Dick will speak at CU-Boulder’s Conference on World Affairs, Thursday, 10:30, at the UMC Central Ballroom. Tillemann-Dick heads up Elevate Quantum, a consortium of over 85 quantum-focused organizations in Colorado and the Mountain West. He’s also the founder and a CEO of the Denver company, Maybell Quantum. It’s named after the tiny town of Maybell, Colorado, which holds the record for the coldest temperature ever recorded in Colorado – Minus 61 Degrees Fahrenheit. Maybell Quantum honors the little town’s record-breaking cold with a refrigerator the company calls “The Icebox” Quantum computers can only operate at the incredibly cold temperature of -441 F. Maybell Quantum’s Icebox” is designed to help quantum processors stay that supercold – which is one of the many keys to unlocking the quantum breakthroughs up ahead.

Colorado River: new deals, old tensions Mar 26, 2024
Show notes

Colorado River: Promise and Peril (start time: 6:28) For more than two decades the Colorado River has been shrinking, afflicted by climate change-induced drought, population growth, and water politics. Some 40 million people living in seven states, and 30 tribes, depend on the river. The Upper Basin — Colorado, Utah, Wyoming and New Mexico– have been at odds with Lower Basin states – California, Nevada and Arizona — over who should do more to cut back on water use. Meanwhile, here in Colorado, cities and towns on the Front Range have been clashing with those on the Western Slope over water from the river. After all, Front Range cities get almost half of their water from the Western Slope, through transmountain diversions. In this week’s show, host Susan Moran interviews two journalists who have been covering water issues in the West. They recently produced a feature on a surprising new water-rights purchase that could ease west-vs-east tensions, while giving endangered fish a leg up. Alex Hager is a reporter covering the Colorado River Basin for KUNC and many NPR network stations. Luke Runyon is co-director of The Water Desk, an initiative of the Center for Environmental Journalism at CU Boulder. Previously he was managing editor and a reporter at KUNC.

Deep-sea Coral Reefs // Mineral-Mining Feb 27, 2024
Show notes

This week’s How On Earth offers two features:

Deep-sea Coral

Deep-sea coral reef discovery (start time: 0:58) Scientists recently discovered and mapped the largest known deep-sea coral reef in the world. It’s located up to 200 miles off the U.S. Atlantic Coast, and it’s larger than Vermont. The news comes as a bright spot for oceans and marine life, when ocean acidification related to global warming, as well as overfishing, have been destroying coral reefs around the world. Contributing host Kara Fox interviews Kasey Cantwell, the operations chief for the Expeditions and Exploration Division of the National Oceanic and Atmospheric Administration, about the big discovery and its implications.

Deep-sea mining: promises and perils (start time: 10:48) Exploratory mining of the ocean floor for minerals began decades ago. Although commercialization remains elusive, some some companies are moving rapidly to exploit the seabed for commercial use. They aim to harness critical minerals – manganese, nickel, copper, cobalt and others – for use in the production of electric vehicle batteries, cell phones, wind turbines, etc. Some scientists, environmentalists, a regulatory body, and even some auto and tech companies, have called for at least a temporary ban on seabed mining, out of concern about its impact on marine life. Host Kara Fox interviews Farah Obaidullah, founder of the conservation group The Ocean and Us, and editor of a book of the same name, about seabed mining.
