# esobio: #ufo, this phenomenon was a lot more than nuts and bolts machines ...

<< The investigative "I-Team" for CBS affiliate KLAS-TV in Las Vegas, NV has brought forward new documents related to the secret Pentagon UFO program first revealed by the New York Times in December. >>

<< The investigations by BAASS (Bigelow Aerospace Advanced Space Studies) provided new lines of evidence showing that the UFO phenomenon was a lot more than nuts and bolts machines that interacted with military aircraft (..) The phenomenon also involved a whole panoply of diverse activity that included bizarre creatures, poltergeist activity, invisible entities, orbs of light, animal and human injuries and much more. >>

# behav: the social / antisocial flexibility of yellow-bellied marmots (M. flaviventer)

<< Humans in strong social relationships are more likely to live longer because social relationships may buffer stressors and thus have protective effects. However, a shortcoming of human studies is that they often rely on self-reporting of these relationships. >>

AA << focused on socially flexible yellow-bellied marmots (Marmota flaviventer) and asked whether female longevity covaries with the specific nature of social relationships. >>

AA << found a significant negative phenotypic correlation between affiliative social relationship strength and longevity; marmots with greater degree, closeness and those with a greater negative average shortest path length died at younger ages. >>

<< sociality plays an important role in longevity, but how it does so may depend on whether a species is obligately or facultatively social. >>

# acad: Prometheus vs Pandora interplay

<< Some of the most important rules we need to discover are about how to use technology and, just as importantly, how not to use it. >>

<< The great institutional economist Clarence Ayres wrote about how technology becomes incorporated into our lives in a way that is roughly equivalent to the way tribal societies use totems to interact with each other. >>

<< Every inventor is both a Prometheus stealing fire from the gods, and a Pandora unwittingly releasing a swarm of potential evils on the world. The competition of ideas between hype and doomsaying allows us to discover helpful rules which deal with both. >>

<< Technology doesn't come with a ready-made rulebook for how to use it. We have to discover this in a process of trial, error and argument. And for this the doomsayer is just as vital as the visionary. >>

# gst: to model a system that can "collapse without warning"

<< Volcanoes progressively weaken and may collapse without warning through hydrothermal alteration. These dangerous mass wasting processes occur less-frequently than eruptions or lahars but the resultant mass flows can be large in size, posing risk to local residents, and businesses. >>

<< Collapses are often multi-hazard events, with even small-scale landslides capable of triggering eruptions or creating break-out lahars. >>

<< These kind of events demonstrated the greater need to understand and assess this process >>

# gene: newtic1 to regenerate limbs

<< The newt, a group of urodele amphibians, has outstanding ability to repeatedly regenerate various body parts >>

<< In this animal, when the limb is amputated, a cell mass named the blastema appears on the stump and eventually gives rise to a new functional limb >>

AA << identified an orphan gene Newtic1, whose transcripts significantly increased in the blastema. Newtic1 was expressed in a subset of erythrocytes that formed a novel clump (EryC) >>

<< When the limb was amputated, EryCs were newly generated in the stump and accumulated into a distal portion of the growing blastema. >>

# gst: Sustainability, Die-off, Collapse, Oscillation: 4 classes of traject. to depict interactions of a resource-intensive tech species with its host planet.

AA << have used the formalism of dynamical systems theory to explore a highly simplified model for the interaction of a resource-intensive technological species with its host planet. >>

AA << find four distinct classes of trajectories (..)

Sustainability: For these classes, stable equilibria (..) exist which can be approached monotonically. The population rises smoothly to a steady-state value. The planetary environment is monotonically perturbed from its initial value e0 and reaches a new steady state that can support a large population.

Die-off: For these classes, stable equilibria (..) exist which cannot be approached monotonically. The population overshoots the environment's carrying capacity, reaches a peak, and is forced to decline as the environment reaches its new steady state.

Collapse: For these classes, stable equilibria with nonzero population do not exist. In these cases the population experiences a rapid decline after reaching its peak value. It is noteworthy that collapse can occur even though the population has begun leveling off due to the civilization's switching from high-impact to low-impact energy modalities.

Oscillation: In this class, a stable limit cycle exists rather than an equilibrium. The population and the planetary environment cycle between high and low values. >>

# brain: understanding of zero even among honey bees

AA << trained individual honey bees to the numerical concepts of "greater than" or "less than" using stimuli containing one to six elemental features. Bees could subsequently extrapolate the concept of less than to order zero numerosity at the lower end of the numerical continuum. Bees demonstrated an understanding that parallels animals such as the African grey parrot, nonhuman primates, and even preschool children. >>
