Big Picture Science - ZZZZZs Please

We’ve all hit the snooze button when the alarm goes off, but why do we crave sleep in the first place? We explore the evolutionary origins of sleep … the study of narcolepsy in dogs … and could novel drugs and technologies cut down on our need for those zzzzs.

Plus, ditch your dream journal: a brain scanner may let you record – and play back – your dreams.

And, branch out with the latest development in artificial light: bioluminescent trees. How gene tinkering may make your houseplants both grow and glow.

Guests:
  • Emmanuel Mignot – Professor of psychiatry and behavioral sciences, and director of the Stanford Center for Sleep Sciences and Medicine, Stanford University
  • Kyle Taylor – Molecular biologist at Glowing Plant
  • Jerry Siegel – Neuroscientist and professor of psychiatry, the University of California, Los Angeles

CME Strike on May 24th

CME STRIKE: As expected, a CME hit Earth's magnetic field on May 24th around 1800 UT. It was just a glancing blow. Nevertheless, the impact could spark polar geomagnetic storms in the hours ahead. High-latitude sky watchers should be alert for auroras shining through the bright moonlight on May 24-25.

CME and Solar Radiation Storm

SIGNIFICANT EXPLOSION: A solar radiation storm is in progress on May 22nd following an M5-class solar flare on the sun's western limb.  The explosion not only accelerated a hailstorm of protons toward our planet, but also produced a magnificent CME, which might deliver a glancing blow to Earth's magnetic field in the days ahead.

Big Picture Science for 05/20/13 - Skeptic Check: Hostile Climate

Image for Big Picture Science weekly radio show
Big Picture Science - Skeptic Check: Hostile Climate

It’s a record we didn’t want to break. The carbon dioxide concentration in the atmosphere has hit the 400 parts-per-million mark, a level at which some scientists say is a point of no return for stopping climate change. A few days later, a leading newspaper prints an op-ed essay that claims CO2 is getting a bad rap: it’s actually good for the planet. The more the better.

Skeptic Phil Plait rebuts the CO2-is-awesome idea while a paleontologist paints a picture of what Earth was like when the notorious gas last ruled the planet. Note: humans weren’t around.

Plus, our skit says NO to O2 … and a claim that climate change skeptics have borrowed from the Creationists’ playbook in challenging the teaching of established science in schools.

Guests:
  • Phil Plait – Astronomer, Skeptic, and author of Slate Magazine’s blog Bad Astronomy
  • Peter Ward – Paleontologist and biologist, Department of Earth and Space Sciences, University of Washington in Seattle

Strong Solar Activity Continues


Source - Space Weather News for May 14, 2013: http://spaceweather.com

Solar activity is high.  During a 24 hour period straddling May 13th and 14th, the sun unleashed three X-class solar flares.  These are the strongest flares of the year so far, and they signal a significant increase in solar activity.  The source of the flares, a large sunspot on the sun's eastern limb, appears poised to erupt again as it turns toward Earth.

X-FLARE: A sunspot hiding behind the sun's eastern limb erupted on May 13th at 02:17 UT, producing the strongest solar flare of the year so far (X1.7).  The blast site  will turn toward Earth in a few days. This will give forecasters a better view of the active region and allow them to gauge its potential for more explosions. Visit http://spaceweather.com for updates and images of today's X-flare.

Big Picture Science - Fundest Show Ever

You can remember yesterday, but not tomorrow. But why is that? We consider the arrow of time and why it all traces to the Big Bang. Also, artificial blood cells and life in a deep Antarctic lake.

You’ll hear how Stephen King thinks that humankind is metaphorically living under a big dome, and what reasons Neil Tyson gives for why we really want to go into space.

And … skeptical takes on faces in cheese sandwiches and the supposedly special powers of psychics.

All this and more on this special Big Picture Science podcast.

ANNULAR ECLIPSE: On May 10th, the South Pacific sun will turn into a ring of fire as the Moon passes directly in front of the solar disk, producing an annular solar eclipse. At maximum, more than 95% of the sun's diameter will be covered over parts of Australia, eastern Papua New Guinea and the Solomon Islands. Please check http://spaceweather.com for more information, including a live webcast from Cape York, Australia, which begins on May 9th at approximately 5 PM EDT.

Big Picture Science - Stomach This

Not all conversation is appropriate for the dinner table – and that includes, strangely enough, the subject of eating. Yet what happens during the time that food enters our mouth and its grand exit is a model of efficiency and adaptation.

Author Mary Roach takes us on a tour of the alimentary canal, while a researcher describes his invention of an artificial stomach. Plus, a psychologist on why we find certain foods and smells disgusting.

And, you don’t eat them but they could wiggle their way within nonetheless: surgical snakebots.

Strong Solar Flare on May 3rd


Source - Space Weather News for May 3, 2013: http://spaceweather.com

STRONG FLARE: For the second time in three days, an active region just over the sun's east limb has exploded, producing a strong solar flare and CME.  The blast on May 3rd registered M5--not quite an X-flare, but still strong considering that the edge of the sun partially eclipsed the explosion as seen from Earth. Solar rotation is turning the active region toward Earth, and it should emerge later this weekend.  Visit http://spaceweather.com for updates.
