Big Picture Science - What Lies Beneath

What you can’t see may astound you.  The largest unexplored region of Earth is the ocean.  Beneath its churning surface, oceanographers have recently discovered the largest volcano in the world – perhaps in the solar system.
 
Find out what is known – and yet to be discovered – about the marine life of the abyss, and how a fish called the bristlemouth has grabbed the crown for “most numerous vertebrate on Earth” from the chicken.
 
Plus, the menace of America’s Cascadia fault, which has the potential to unleash a devastating magnitude 9 earthquake. 
 
Follow Dr. Sager’s voyage back to Tamu Massif in Fall 2015.

Aurora Watch, Aug.27-28


Source - Space Weather News for Aug. 27, 2015: http://spaceweather.com

Earth's polar magnetic field is storming as our planet passes through a region of south-pointing magnetism in the solar wind.  Last night (Aug. 26-27), observers around the Arctic Circle saw some of their first auroras in months and Northern Lights descended across the Canadian border into multiple US states.  Solar wind conditions favor more geomagnetic storms and high-latitude auroras on Aug. 27-28.  Check http://spaceweather.com for more information and updates.

AURORA ALERTS:  Don't sleep through the auroras.  Get a phone call when geomagnetic storms are underway.  Space weather alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).

Big Picture Science for Monday 24 August 2015 - The Light Stuff











Big Picture Science - The Light Stuff

The light bulb needs changing.  Edison’s incandescent bulb, virtually unaltered for more than a century, is now being eclipsed by the LED.  The creative applications for these small and efficient devices are endless: on tape, on wallpaper, even in contact lenses.  They will set the world aglow.  But is a brighter world a better one?
 
Discover the many ingenious applications for LEDs and the brilliance of the 19th century scientist, James Clerk Maxwell, who first discovered just what light is.  But both biologists and astronomers are alarmed by the disappearance of dark.   Find out how light pollution is making us and other animals sick and – when was the last time you saw a starry night?

Big Picture Science - Skeptic Check: Skeptic Seth


Are you skeptical?  Sure, you raise an eyebrow when some Nigerian prince asks for your bank numbers, or when a breakfast cereal claims that it will turn your kid into a professional athlete overnight.

But what do you really know about the benefits of organic milk?  Or the power of whitening ingredients in your toothpaste?  How credible is what you read on Twitter?

Today, information overwhelms us, and the need to keep our skeptical wits about us has never been greater.  We follow Seth around as he faces the daily onslaught of hype and hokum.

It’s Skeptic Check, our monthly look at critical thinking … but don’t take our word for it!

Big Picture Science for Monday 10 August 2015 - Solar System Vacation












Big Picture Science - Solar System Vacation

Ever gone bungee jumping on Venus?  Of course not.  No one has.  However your great-great-great grandchildren might find themselves packing for the cloudy planet … or for another locale in our cosmic backyard.  That’s what we picture as we accelerate our imagination to escape velocity and beyond – and tour vacation spots that are out of this world.

An enormous mountain and an impressive canyon await you on Mars.  If the outer solar system is more your thing, consider making a ten minute free-fall on Miranda, a moon of Uranus, or step up to the challenge of playing catch on an asteroid..

Also, just opened up: Pluto. A member of the New Horizons science team describes why the dwarf planet could be a holiday haven.  Bring your crampons for ice climbing!

Guests:

•   Andrew Fraknoi – Chair of the astronomy department, Foothill College
•   Lori Fenton - Planetary scientist, SETI Institute 
•   David Grinspoon – Astrobiologist, author of Venus Express

Big Picture Science for Monday 03 August 2015 - The Fix is In












Big Picture Science - The Fix is In

The moon jellyfish has remarkable approach to self-repair.  If it loses a limb, it rearranges its remaining body parts to once again become radially symmetric.  Humans can’t do that, but a new approach that combines biology with nanotechnology could give our immune systems a boost.  Would you drink a beaker of nanobots if they could help you fight cancer?
 
Also, materials science gets into self-healing with a novel concrete that fixes its own cracks. 
 
Plus, why even the most adaptive systems can be stretched to their limit.  New research suggests that the oceans will take a millennium to recover from climate change.

Big Picture Science - Skeptic Check: Are You Sure You’re Sure?

ENCORE: Nuclear fission powers the Sun. Or is it fusion? At any rate, helium is burned in the process, of that you are certain. After all, you read that article on astronomy last week*.
 
You know what you know. But you probably don’t know what you don’t know. Few of us do. Scientists say we’re spectacularly incompetent at recognizing our own incompetency, and that sometimes leads to trouble.
 
Find out why wrongness is the by-product of big brains and why even scientists – gasp! – are not immune. Plus, a peek into the trash bin of history: the biggest scientific blunders and the brighter-than-bright brains that made them. Including Einstein.
 
*Oh, and the Sun burns hydrogen to produce helium. But then, you knew that.
 
Guests:
•   David Dunning – Psychologist, Cornell University. His cover story, “We Are All Confidence Idiots,” appeared in the November/December issue of The Pacific Standard.
•   Robert Burton – Neurologist, author, On Being Certain: Believing You Are Right Even When You’re Not and A Skeptic’s Guide to the Mind: What Neuroscience Can and Cannot Tell Us About Ourselves
•   Brendan Nyhan – Political scientist, Dartmouth College

Big Picture Science for Monday 20 July 2015 - Moral’s Law












Big Picture Science - Moral’s Law

“If it bleeds, it leads” is the tried and true tenet of news.  Indeed, headlines are often no more than a long list of moral atrocities.  Yet one man argues that we’re living in the most civilized era in history.  And he credits this to scientific thought and reason. 

Hang on!  Our executive function isn’t enough to promote ethical behavior, says a psychologist.  The real fuel behind our drive to be good?  Anger, compassion, pride: your emotions!
 
But whether or not you’re a pillar of the community, good intentions might all be for naught when future ethical decisions are made by our silicon successors.  Get ready for moral machines. Or not.

Guests:

•   Michael Shermer - Publisher of Skeptic Magazine, author of The Moral Arc: How Science and Reason Lead Humanity Toward Truth, Justice, and Freedom
•   David DeSteno – Psychologist, Northeastern University, author of The Truth About Trust
•   Colin Allen – Historian, philosopher of science and cognitive science, Indiana University.  Co-author of Moral Machines: Teaching Robots Right From Wrong
