The Starmus Festival

news-placeholder-Starmus-e1517313691450Woodstock.  Lallapalooza. Lilith Fair.  Coachella.  Burning Man.  All famous music and art festivals.  What about…science festivals?  Perhaps a festival with all the “rock stars” of science and space exploration, and while you’re at it, throw in a few music rock stars as well?  Well, that describes the Starmus Festival.  Starmus is the brain child of Dr. Garik Israelian, an astrophysicist who led the team that found the first observational evidence that supernova explosions are responsible for the formation of stellar mass black holes. We talk with Dr. Israelian about the past, present, and future of Starmus.

Spaceport Earth

Spaceport Earth by Joe Pappalargo

Spaceport Earth. This week on How on Earth, we speak with Joe Pappalardo about his book “Spaceport Earth”. With the successes of Space-X and Blue Origin, private and commercial spaceflight is a fast growing business. Pappalardo talks with us about this new space industry and the advances and setbacks that have been faced. In particular, Pappalardo shares his knowledge about the spaceports, new and old, that are part of the new space endeavours. We also talk about how these new launch opportunities provide new ways to support the scientific exploration of both Earth and space.

2017 Look Back – 2018 Look Forward

2017For this end-of-the-year/start-of-the-year  How on Earth show, we look back to 2017 with clips from some of our features from the past year: selections about tracking methane leaks, ketogenic diets, using MDMA to treat PTSD, gravitational waves, the solar eclipse, space missions, and the politicization of science.  Those are just a few of the topics we covered in 2017, which also included: the continuation of the Our Microbes, Ourselves series, global warming and climate change, research about aging, mutant proteins, how humans have altered nature, future technologies, nuclear tests and the Van Allen belts, biofuels, extinctions following an asteroid impact, monorails, life expectancy in America,  observing stellar occultations by objects in the distant solar system, space shields for satellites, virtual colonoscopies, the Search for Extraterrestrial Intelligence (SETI), chronic fatigue syndrome, protecting pollinators, testing our drinking water, cancer, the Long Now foundation, citizen science, fracking, and more!

The Cassini Mission to Saturn

pia03883-nohuygensThe Cassini mission to Saturn launched 20 years ago, on October 15, 1997.  It took seven years to reach Saturn, and has been orbiting and intensely studying Saturn ever since…until last week when the mission ended in a final dive into Saturn’s atmosphere.  The mission studied Saturn, its famous rings, and its many moons using a suite of instruments that observed a broad range of wavelengths from ultraviolet, to visible, infrared, and radio as well as examining dust, charged particles, and magnetic fields.  It also delivered the Huygens probe that descended through the atmosphere of Saturn’s giant moon, Titan.

In this edition of How on earth, we have two scientists from the Cassini mission team.  Dr. Larry Esposito is a Professor at the Astrophysical and Planetary Sciences department at the University of Colorado at Boulder and member of the Laboratory for Atmospheric and Space Physics at CU.  Dr. Carly Howett is a planetary scientist and manager at the Southwest Research Institute in Boulder.  They share with us some of the science from Cassini-Huygens and experiences working on such a long-term and successful space mission.

Biofuels Tradeoffs

corn-field-farm-vertical-PA
 Biofuels Tradeoffs (start time: 8:27): In this week’s show David DeGennaro, an agriculture policy specialist with the National Wildlife Federation and author of a report called “Fueling Destruction,”  talks with host Susan Moran about the environmental consequences of biofuels, and about possible solutions. The Environmental Protection Agency has proposed maintaining record support for biofuels, namely corn. Last week the EPA ended an open public comment period leading up to a decision to maintain, increase or scale back its current support of biofuels as part of the Renewable Fuels Standard, a federal mandate to blend corn-based ethanol and other renewable fuels into conventional gasoline. NWF and some other environmental organizations, along with former California Congressman Henry Waxman, have been urging the EPA and Congress to reduce biofuels mandates. Increased demand for corn has led to the conversion of millions of acres of habitat-rich grasslands and into croplands — all without significantly reducing greenhouse gas emissions.

Climate Change and Extinctions Following an Asteroid Impact

asteroid_impactClimate Change and Extinctions Following an Asteroid Impact (starts at 8:45) It has been hypothesized that the dinosaurs were killed off by a large asteroid that struck the Earth. The details of how the impact of a 10 kilometer diameter asteroid led to global scale extinction have remained elusive. Recently, climate researchers from the Boulder area published new climate model results that show how the asteroid impact ultimately leads to widespread cooling in the atmosphere and increased exposure to ultraviolet radiation. These drastic and rapid changes to the climate due to the asteroid impact may explain the global scale extinction.

Two of the authors join us today to talk about this new research. Dr. Charles Bardeen works as a scientist at the National Center for Atmospheric Research, and is the lead author of the new paper. Joining Dr. Bardeen is Professor Brian Toon, a co-author of the new research and a professor at the University of Colorado, Boulder.

Stay Young – If You’re a Worm

Age
Age

This week on How on Earth, Beth spoke with Dr Gordon Lithgow, a researcher at the Buck Institute for Aging in California who studies aging in nematode worms. Stress actually keeps us young by activating systems that repair and maintain cells. These stresses can be things like caloric restriction and exercise. Eventually the molecular bases of these stresses will be identified and may lead to interventions to slow aging.

Mortality Trends in America // Life Expectancy in America

This week on How on Earth we look at the scientific research into the lifespans of Americans.

Andrea Tilstra

Mortality trends in America (start time 4:05): We speak with Andrea Tilstra, who co-authored a recent paper on mortality trends in America. Tilstra is a co-author of a recent study published in the International Journal of Epidemiology.  Her team’s paper is titled “Explaining recent mortality trends among younger and middle-aged White Americans.”

Life expectancy in America (start time 12:40): Next, we speak with Jay Olshansky, who ten years ago first predicted the recently observed drop in life expectancy in America. Olshansky is a world renowned expert in the Science of Aging.  As for his crystal ball – well, it has little to do with magic, and more to do with his understanding about how our cells work, and how they age.  It also helps that he understands statistics.

Chasing Shadows – Stellar Occultations and the Outer Solar System

Chasing Shadows [starts at 9:40]  Astronomy is a science that depends on watching things happen in the universe that we don’t have control over: supernovae, formation of stars, orbits of planets, and the spectacle of solar eclipses.  You can’t grab a distant galaxy and bring it into the lab for experiments, so astronomers have to depend on studying the light that fortuitously comes to them from distant objects.  However, by studying just that light, we can learn much about the objects in the universe and how they formed and evolved.  For example, studying solar eclipses have taught us about the corona of the sun and about general relativity.   To make those observations and measurements, scientists have to chase the shadow and set up their laboratory in remote places to catch it.  In this edition of How on Earth we talk with one such shadow-chaser: astronomer Dr. Marc Buie from the Boulder office of the Southwest Research Institute.  Marc organized a set of expeditions around the Earth to observe occultations of the Kuiper belt object 2014 MU69, which is is the next flyby target of the New Horizons space mission that flew past Pluto in July 2015.  He explains the science of occultations, what can be gleaned from these shadowy observations of 2014 MU69, and talks about planning for observation expeditions to remote places around the world.
