Conscious Choice cover

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

Birds that can fly practically forever

New research using data loggers tagged to thirteen common swifts has revealed that these birds were capable of remaining airborne for months at a time.

The researchers found that some of the birds made a few brief night landings in winter but remained airborne for 99% of the time. Three birds didn’t touch down once in the entire ten months….“Common swifts have evolved to be very efficient flyers, with streamlined body shapes and long and narrow wings, generating lift force at low cost,” says Anders Hedenström, a study co-author and a biologist at Lund University in Sweden. The birds even eat while airborne, snatching flying termites, ballooning spiders and other aerial insects for in-flight meals.

Hedenström says that common swifts have adapted to a low-energy lifestyle, but his team does not yet know whether the birds sleep while aloft. “Most animals suffer dramatically from far less sleep loss,” says Niels Rattenborg, a neurobiologist at Max Planck Institute for Ornithology in Seewiesen, Germany. “But these birds seem to have found a trick through evolution that allows them to get by on far less sleep.”

    Many animals, including dolphins and many birds only turn off one side of their brain at a time when they sleep, I guess the swift manages to do it while in flight.

    Andrew_W–
    (hey)
    Interesting stuff.
    If I’m not mistaken, Dolphins manage to breath even when they “sleep.” (?)
    (as an aside– most of our “sleep research” has historically been derived from the study of Cat’s.)

    There are specific high-potency benzodiazepines that have an ability to disconnect higher-level brain functioning in humans, from differently ordered functioning such as (sleep) walking, driving a car, and flying across-country (in an airplane that is, not via the Swift, method).
    (The short-term, hi-potency varieties, such as Versed & other hypnotics, amongst the benzo anti-anxiety class of meds, Librium & Valium being the prototypes.)
