Skulls in the Stars

“Dr. SkySkull” selects several notable posts each week from a miscellany of ResearchBlogging.org categories. He blogs at Skulls in the Stars.

• Study: More Privilege Means Less Empathy. David Berreby at Mind Matters describes some interesting research that suggests that, the higher up in social status one is, the less empathy one has for others.  Though it will surely be used as political fodder, the study has important implications for the study of class relations.
• Lunar lost and found. Forty years ago, a Soviet  lunar rover landed on the Moon.  Though it provided some initial data, it was more or less lost until recently, when the Lunar Reconnaissance Orbiter found it again!  Emma at we are all in the gutter provides the details.
• To see the world in a grain of sand – movement from a turtle hatchling’s perspective. This may sound like a biology post, but it also includes a significant amount of physics!  Turtle hatchlings must deal with a daunting variety of sand conditions in their voyage from next to water, and their motion is optimized for each condition.  Alistair Dove in Deep Type Flow takes us on a journey with the turtles, explaining how and why they move the way they do.
• The Blood of Louis XVI. Researchers are now using blood samples from the executed monarch Louis XVI to reconstruct his genetic profile.  The source of this blood is a rather ghastly one, and Terri Sundquist of Promega Connections gives us the science and the history behind it.
• Faunal Friends: Evolution and the Animal Connection. Human beings love animals; it is natural for scientists to seek to understand this rather unique tendency for cross-species bonds.  Krystal D’Costa of Anthropology in Practice walks us through the origins of our love for many creatures great and small.

Have a happy Thanksgiving, and check back next Monday for more selections!

The Giants’ Shoulders #29 is now up at Heterodoxolgy, and it is an “esoteric sciences special”! The carnival focuses on the strange, alien and counterintuitive in the history of the sciences.  Thanks to Egil for putting together a lovely carnival!

Giants’ Shoulders #30, A (Scientific) Christmas Carol, will be hosted by the Ghost of William Whewell in person at his very own blog on 16^thDecember 2010 and is a celebration of the science of the 19^th century. Submissions should be made to Rebekah Higgitt or to the Giants’ Shoulders Blog Carnival by 15^th December.  (I’ve already got the perfect topic for my post!)

• The demon is out of the bottle. No, we haven’t regressed to a superstitious era of witches and demons — we’re talking about Maxwell’s demon, a hypothetical Second Law of Thermodynamics-violating creature!  It is well-known now that this “demon” can’t violate the Second Law, but Joerg Heber at All That Matters describes an experiment that demonstrates explicitly the relationship between the demon and energy.
• Could “hairier” crops help mitigate climate warming? Humankind plays such a large role in our planet’s ecosystem that it is easy to forget that unusual and offbeat changes can affect the climate in significant ways.  Phil Camill at Global Change describes one of these odd possibilities — changing the reflectivity of the planet’s surface by using “hairier” crops — and the pros and cons of such an approach.
• Mini frog packs a powerful punch. In a wonderfully written piece, Grrlscientist of Punctuated Equilibrium introduces us to a newly-discovered species of poisonous tree frog — and the efforts to determine how it achieves its toxic “punch”.
• The Mines of the Future and of the Past. A disastrous 1527 Spanish expedition left only a handful of survivors who traveled across the Southwest for years to find save haven.  Along the way, some natives gave them a gift made of copper that sparked a mystery — where did the copper come from?  At Gambler’s House, teofilo looks into the origins of the copper artifacts used by the Southwest natives, and what those origins can tell us about our future.

• Life in the dark. Most of us live in areas of near-endless light —  night is filled with the glow of man-made illumination.  In a fascinating post, Greg Downey of Neuroanthropology discusses the effects — physiological and cultural — of living in in a region of genuinely dark nights.
• A galaxy far, far away… While we’re thinking about peering out into the darkness, Kelly Oakes of basic space describes the observation of the most distant object yet in the universe — so distant, in fact, that it formed in an era when galaxies and stars were just forming!
• Finding science in my mother’s jewelry box. Remarkable natural phenomena can be seen all around us, sometimes in the most unlikely of places!  Starting from her mother’s jewelry, Kelly Grooms of Promega Connections takes us 50 million years into the past to learn about our planet’s ancient geology.
• C is for Cookie: Cookie Monster, Network Pressure, and Identity Formation. Alas, poor Cookie Monster — he isn’t the same sugar-gobbling beast that he was when I was a kid!  Now that he only eats a cookie after filling up on vegetables, Krystal d’Costa of Anthropology in Practice explains how we can learn about social network pressure from his change in diet.

There’s only 7 days left before the deadline of the next edition of The Giant’s Shoulders history of science blog carnival!  It will be hosted by Egil Asprem at Heterodoxology, and will be another themed edition:

To the layman, the natural sciences have become increasingly “esoteric” in the sense of being hard to access and difficult to understand. Throughout its history, science has been esoteric in other senses as well, connected with attempts to unravel the secrets of the book of nature, the understanding of occult properties and forces, and the quest for absolute, higher knowledge. This edition of Giants’ Shoulders is dedicated to all those esoteric pursuits of knowledge; a celebration of all strange, alien, and counterintuitive methods that have been attempted to dissect, read, or tame nature’s secrets, from renaissance natural philosophy to present-day Grand Unified Theories – whether cleverly inventive, hopelessly megalomaniac, or simply misguided.

Of course, we’re also still accepting more general posts on the history of science, so get writing for the November 15th deadline; entries can be submitted directly to your host or to the Giants’ Shoulders blog carnival.
