Big Picture Science for 04/21/14 - Happily Confused

Big Picture Science - Happily Confused

Do you feel happy today? How about happily disgusted? Maybe sadly surprised, or sadly disgusted? Human emotions are complex. But at least they’re the common language that unites us all – except when they don’t. A tribe in Namibia might interpret our expression of fear as one of wonderment. And people with autism don’t feel the emotions that others do.

So if you’re now delightfully but curiously perplexed, tune in and discover the evolutionary reason for laughter … how a computer can diagnose emotional disorders that doctors miss … and why the world’s most famous autistic animal behaviorist has insight into the emotional needs of cattle.

Weekend Geomagnetic Activity


Source - Space Weather News for April 20, 2014: http://spaceweather.com

INCOMING STORM CLOUDS:  Three or four CMEs that left the sun earlier this week will arrive in quick succession this weekend.  Mostly, the blows they deliver to Earth's magnetic field are expected to be weak, but the combined impacts could stir up significant geomagnetic activity.  NOAA forecasters put the odds of a high-latitude geomagnetic storm at 55% on Saturday, increasing to 75% on Sunday.

Colorful Lunar Eclipse set for Tuesday Morning


Source - Space Weather News for April 13, 2014: http://spaceweather.com

TOTAL LUNAR ECLIPSE: On Tuesday morning, April 15th, the full Moon will pass through the shadow of Earth, producing a colorful lunar eclipse.  Although the mainstream media is calling this a "blood moon," the color is more likely to be bright orange.  At the moment, Earth's stratosphere is not dusty enough produce a shadow with the deep red hues of blood.  Whatever color it turns out to be, the eclipse will be visible from North and South America, Australia and New Zealand.   Check http://spaceweather.com for observing tips and more information.

LIVE WEBCAST OF THE ECLIPSE: Got clouds? No problem. The lunar eclipse will be broadcast live on the web by the Coca-Cola Science Center at Columbus State University in Georgia: http://www.ccssc.org/webcast.html

Big Picture Science - That's Containment!

ENCORE: We all crave power: to run laptops, charge cell phones, and play Angry Birds. But if generating energy is easy, storing it is not. Remember when your computer conked out during that cross-country flight? Why can’t someone build a better battery?

Discover why battery design is stuck in the 1800s, and why updating it is key to future green transportation (not to mention more juice for your smartphone). Also, how to build a new type of solar cell that can turn sunlight directly into fuel at the pump.

Plus, force fields, fat cells and other storage systems. And: Shock lobster! Energy from crustaceans?

Guests:
  • Dan Lankford – Former CEO of three battery technology companies, and a managing director at Wavepoint Ventures
  • Jackie Stephens – Biochemist at Louisiana State University
  • Kevin MacVittie – Graduate student of chemistry, Clarkson University, New York
  • Nate Lewis – Chemist, California Institute of Technology
  • Alex Filippenko – Astronomer, University of California, Berkeley
  • Peter Williams – Physicist, San Francisco Bay Area

Separated at Launch: NASA to Study Twin Astronauts


Source - NASA Science News for April 10, 2014

In 2015, with the assistance of the world's only twin astronauts, NASA will conduct an unprecedented experiment in human biology. While one twin remains on the ground, the other will circle Earth aboard the International Space Station for a full year. Will the twins still be identical when they are re-united? The answer could help NASA make space travel safer for generations of astronauts to come.

Big Picture Science - Since Sliced Bread

Happy Birthday, World Wide Web! The 25-year-old Web, along with the Internet and the personal computer, are among mankind’s greatest inventions. But back then, who knew?

A techno-writer reminisces about the early days of the WWW and says he didn’t think it would ever catch on.

Also, meet an inventor who claims his innovation will leave your laptop in the dust. Has quantum computing finally arrived?

Plus, why these inventions are not as transformative as other creative biggies of history: The plow. The printing press. And… the knot?

And, why scientific discoveries may beat out technology as the most revolutionary developments of all. A new result about the Big Bang may prove as important as germ theory and the double helix.

Arctic Melt Season Lengthens

A new study shows that the length of the melt season for Arctic sea ice is growing by several days each decade. This is allowing the Arctic Ocean to absorb enough additional solar radiation in some places to melt as much as four feet of the Arctic ice cap's thickness.

Big Picture Science - Skeptic Check: Evolutionary Arms Race

It’s hard to imagine the twists and turns of evolution that gave rise to Homo Sapiens. After all, it required geologic time, and the existence of many long-gone species that were once close relatives. That may be one reason why – according to a recent poll – one-third of all Americans reject the theory of evolution. They prefer to believe that humans and other living organisms have existed in their current form since the beginning of time.

But if you’ve ever been sick, you’ve been the victim of evolution on a very observable time scale. Nasty viruses and bacteria take full advantage of evolutionary forces to adapt to new hosts. And they can do it quickly.

Discover how comparing the deadly 1918 flu virus with variants today may help us prevent the next pandemic. Also, while antibiotic resistance is threatening to become a major health crisis, better understanding of how bacteria evolve their defenses against our drugs may help us out.

And the geneticist who sequenced the Neanderthal genome says yes, our hirsute neighbors co-mingled with humans.

It’s Skeptic Check … but don’t take our word for it!

X-Flare Produces 'Magnetic Crochet'


Source - Space Weather News for March 30, 2014: http://spaceweather.com

X-FLARE:  The magnetic canopy of sunspot AR2017 erupted yesterday, March 29th, producing an impulsive X1-class solar flare.  Ionizing radiation from the flare produced electrical currents in Earth's upper atmosphere and a ripple in Earth's magnetic field detected by magnetometers across the dayside of our planet. 

Read more about this rare "magnetic crochet" and the possibility of more X-flares this weekend on today's edition of http://spaceweather.com.
