Lunar Transit of the Sun


Source - Space Weather News for Jan. 29, 2014: http://spaceweather.com

LUNAR TRANSIT:  The Moon is about to pass in front of the sun, producing an eclipse that can be seen only from space.  NASA's Solar Dynamics Observatory will record the 2.5-hour  "lunar transit" beginning at 1331 UTC or 8:31 EST on Thursday, Jan. 30th.  Tune into http://spaceweather.com for pictures during the event.

SOLAR FLARES: A large and moderately active sunspot is slowly turning toward Earth, increasing the chances of geoeffective solar activity this week.

Big Picture Science for 01/27/14 - The Pest of Us

Big Picture Science - The Pest of Us

Picture a cockroach skittering across your kitchen. Eeww! Now imagine it served as an entrĂ©e at your local restaurant. There’s good reason these diminutive arthropods give us the willies – but they may also be the key to protein-rich meals of the future.

Get ready for cricket casserole, as our relationship to bugs is about to change.

Also, share in one man’s panic attack when he is swarmed by grasshoppers. And the evolutionary reason insects revolt us, but also why the cicada’s buzz and the beetle’s click may have inspired humans to make music.

Plus, the history of urban pests: why roaches love to hide out between your floorboards. And Molly adopts a boxful of mealworms.

Climate Warming Trend Sustained in 2013


NASA Science News for Jan. 21, 2014

NASA scientists say 2013 tied with 2009 and 2006 for the seventh warmest year since 1880, continuing a long-term trend of rising global temperatures. With the exception of 1998, the 10 warmest years in the 134-year record all have occurred since 2000, with 2010 and 2005 ranking as the warmest years on record.

Big Picture Science for 01/20/14 - Forget to Remember

Big Picture Science - Forget to Remember

You must not remember this. Indeed, it may be key to having a healthy brain. Our gray matter evolved to forget things; otherwise we’d have the images of every face we saw on the subway rattling around our head all day long. Yet we’re building computers with the capacity to remember everything. Everything! And we might one day hook these devices to our brains.

Find out what’s it’s like – and whether it’s desirable – to live in a world of total recall. Plus, the quest for cognitive computers, and how to shake that catchy – but annoying – jingle that plays in your head over and over and over and …

Big Picture Science - Skeptic Check: Zombies Aren't Real

ENCORE: Zombies are making a killing in popular culture. But where did the idea behind these mythical, cerebrum-supping nasties come from? Discover why they may be a hard-wired inheritance from our Pleistocene past.

Also, how a whimsical mathematical model of a Zombie apocalypse can help us withstand earthquakes and disease outbreaks, and how the rabies virus contributed to zombie mythology.

Plus, new ideas for how doctors should respond when humans are in a limbo state between life and death: no pulse, but their brains continue to hum.

Meet the songwriter who has zombies on the brain …. and we chase spaced-out animated corpses in the annual Run-For-Your-Lives foot race.

Starting Fire with Water


Source - NASA Science News for Jan. 10, 2014

Astronauts on the ISS are experimenting with a form of water that has a strange property: it can help start fire. This fundamental physics investigation could have down-to-Earth benefits such as clean-burning municipal waste disposal and improved saltwater purification.

Hubble Images Become Tactile 3-D Experience for the Blind


Below is some of the text from an article posted on the NASA Hubble Space Telescope site on the use of 3-D printing to produce tactile 3-D astronomical images for the blind and visually impaired:

"Three-dimensional printers are transforming the business, medical, and consumer landscape by creating a vast variety of objects, including airplane parts, football cleats, lamps, jewelry, and even artificial human bones."

"Now astronomers Carol Christian and Antonella Nota of the Space Telescope Science Institute in Baltimore, Md., are experimenting with the innovative technology to transform astronomy education by turning images from NASA's Hubble Space Telescope into tactile 3-D pictures for people who cannot explore celestial wonders by sight. The 3-D print design is also useful and intriguing for sighted people who have different learning styles, said the researchers. Christian and Nota admit their task is a challenge because astronomers really can't see space objects in three dimensions."

Huge Sunspot Erupts


Source - Space Weather News for Jan. 7, 2014: http://spaceweather.com

STRONG SOLAR ACTIVITY:  One of the largest sunspots in years, AR1944, has turned toward  Earth and it is crackling with strong flares.  So far on Jan. 7th, the active region has produced M7- and X1-class eruptions, and more appear to be in the offing.  As this alert is being issued, analysts are waiting for more data from solar observatories to clarify the possibility of CME impacts and geomagnetic storms in the days ahead.

For updates, stay tuned to: http://spaceweather.com.

SOLAR FLARE ALERTS:  Would you like a call the next time sunspot AR1944 erupts? X-flare alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).

Big Picture Science - Can We Talk?

ENCORE: You can get your point across in many ways: email, texts, or even face-to-face conversation (does anyone do that anymore?). But ants use chemical messages when organizing their ant buddies for an attack on your kitchen. Meanwhile, your human brain sends messages to other brains without you uttering a word.

Hear these communication stories … how language evolved in the first place… why our brains love a good tale …and how Facebook is keeping native languages from going extinct.

New Year's Day Solar Flares


Source - Space Weather News for Jan. 2, 2014: http://spaceweather.com

SOLAR ACTIVITY: The New Year began with a burst of solar activity.  Active sunspot AR1936 is crackling with strong M-class solar flares, including an M9.9 event on Jan. 1st that stopped just short of becoming a powerful X-flare. Also on New Year's Day, another large sunspot emerged over the sun's eastern limb: AR1944 appears set to add its own contribution to the fusillade of explosions.
