Korea Aerospace University and KIST plan solar-powered UAV
Eco Factor: Zero-emission UAV designed to fly on solar energy.
Korea Aerospace University and the Korea Institute of Science and Technology have signed a MoU to develop a solar-powered unmanned aerial vehicle that can hover at an altitude of 20,000m for several months before landing.
The UAV will use KAU?s design technology for mid-altitude unmanned aerial vehicles and KIST?s solar cell power generation to provide all the electricity the drone requires. The UAV will have a wingspan of 40m, to which solar cells will be attached.
Solar panels will generate all the electricity the drone needs to power its motor-operated propeller. These photovoltaic panels will also store energy in a Li-ion battery pack to power the UAV after dark. The first prototype of the UAV with a 4m wingspan is expected to be flown on a pilot run by 2012, after which the full-sized UAV will take on the skies.

Science Art: Cormorant, by Bob Hines.
These are cormorants – the birds that swim underwater to catch fish. I fell in love with cormorants reading Ping as a little boy (on the mighty Yangtse, boat-dwellers put rings around their necks and train them to retrieve fish), and was lucky enough to grow up in an area where cormorants and their cousins, anhingas, were relatively populous. You could see them sunning on the side of the road, drying out before another dive.
I always liked the design of their necks and beaks – sort of Art Nouveau curves, as if they’d been designed by Aubrey Beardsley.
This image, drawn by Bob Hines, comes from the U. S. Fish and Wildlife Service.

Science Art: ?A Pigeon Fancier?s Manual,? by Ruth Padel.
I found this poem among three books of scientific poetry reviewed in Science Magazine, 2 October 2009. It’s from Darwin: A Life in Poems by Ruth Padel, ISBN 9780701183851. There’s a note at the bottom of the poem – all the quotations are from Darwin himself.
A Pigeon Fancier’s Manual
“This horrid Species thing.” He’s got to write it new –
and smaller! Just (just!) summarizing his views.
“My rag of a book. It cost me so much labour
I almost hate it.” They build a billiard room
beside the study. He pots coloured balls like sweets
as a rest from work. She protects him from visitors
and relatives. No one’s ill – they take a family holiday
on the Isle of Wight. He finishes in April.
The publisher’s reader says, “Make it a manual
on pigeon-breeding! Forget the rest.
Everyone loves pigeons – it’d be reviewed
by every journal in the land.” John Murray knows
a good thing when he see

The Case for a Creator: A Universe Not Made For Us
The Case for a Creator, Chapter 7
The final section of this chapter concerns Gonzalez's argument that the Earth is uniquely designed to make scientific discovery possible. His argument is that our planet is fine-tuned not just to allow the existence of life, but to allow us to find out important facts about the nature of [...]

Stars (not seen before)
NASA is very excited about its newly-launched satellite called WISE, which will detect stars, "failed stars," asteroids, and other interstellar bodies with infra-red technology. In the words of the press release: To sense
the infrared glow of stars and galaxies, the WISE spacecraft cannot give off
any detectable infrared light of its own. This is accomplished by chilling the
telescope and detectors to ultra-cold temperatures. The coldest of WISE's
detectors will operate at less than 8 Kelvin, or minus 445 degrees Fahrenheit. Here's the "first light" image, of the Carina constellation, including about 3,000 stars. This in a portion of the sky about three
times as big as the moon. Appears the image is even more impressive than the technology.

Pandas and galaxies
At the moment, it's just me and all the country's astronomers. What I mean is, I've accompanied Jo to DC, where he's attending a huge astronomy conference, and I'm watching cuddly pandas eat bamboo (the hotel's just next to the zoo and not a whole lot else), going to obscure museums (so far, I've seen exhibits on avant-garde Japanese fashion and American Jewish soldiers and the post-WWII DP camps), appreciating Whole Foods store-brand granola in a city that no doubt has good food somewhere but not somewhere I've found it, and pretending that DC in an especially cold winter is walkable, which, even with extreme layering, it's not. Anyhow. WANT! (Yes, my purpose in life is to lower the average IQ in this astronomer-filled hotel.) While others study the galaxy, I just attempt to dress like it. Tragically, the $30 skirt is out of stock. These, meanwhile, are perfection, and would be an exception to my anti-leggings-as-pants rule. If there is a source for space-print material, and I could g

What If Carbon Weren?t A Problem?
“A new study shows that Earth’s ability to absorb carbon dioxide from all sources, including man, has remained unchanged for 160 years. As it turns out, there may be no carbon to offset.”
Read the rest, if you do nothing else today.

Da Vinci Studies of Fetuses, photo by Luc Viatour.
Click to embiggen.
These are notes and pen-over-chalk sketches of a 4-month-old fetus (and the structure of the placenta) as seen by Leonardo da Vinci. The first idea of the fetal position came from this notebook. I’m working hard not to think about how Leonardo came to draw this picture.
The photograph of the notebook was taken by Luc Viatour, who has many other marvelous scientific images in his portfolio (as well as gorgeous pictures of European architecture and beautiful Belgians).
Happy New Year.

Emanuel, Prinn, Lindzen Debate CRU-Hack at MIT
Meteorology (EAPS in MIT-speak) professors Kerry Emanuel, Ronald Prinn, and Richard Lindzen, discussed the hacked emails (widely pimped as "ClimateGate") from the Climate Research Unit of the University of East Anglia with two political scientists on December 10.Emanuel: What we have here are thousands of emails collectively showing scientists hard at work, trying to figure out the meaning of evidence that confronts them. Among a few messages, there are a few lines showing the human failings of a few scientists? Lindzen: . . .things that are unethical and in many cases illegal . . . willingness to destroy data rather than release it . . . bad things going on . . . elite hysteria . . . devastating for popular support for science . . . scandals, cheating and arguments . . . bizarre changes [to the data] . . . The public is being thrown catastrophes. Prinn: My view of the risk is that we have no other planet to retreat to if we are wrong. Video below (running time 1:58:31):
