Broadband is a human right in Kentucky
Just as important as electricity and running water, says state’s housing corporation. A US state has decided that a broadband connection is as much a human right as electricity and running water.
The Kentucky Housing Corporation (KHC), which builds low-income housing in the state, has listed broadband internet access among the inalienable rights of its residents. vnunet.com
The Photographer’s Right:
your rights and remedies when stopped or confronted for photography: “a downloadable guide that is loosely based
on the ACLU’s Bust Card and the Know Your Rights flyer. It may be downloaded
and printed out using Adobe Acrobat Reader. You may make copies and carry
them your wallet, pocket or camera bag to give you quick access to your
rights and obligations concerning confrontations over photography…”
Brain’s response to addictive drugs, stress:
This is big. Stanford researchers have characterized a central mechanism underlying addiction, regardless of which substance a subject is addicted to. It appears to involve dopamine-induced sensitization of neurons in a brain region called the ventral Tegmental area to another neurotransmitter, glutamate. Interestingly, the same process occurs in response to stress. Neuronal sensitization to glutamate is at the core of the biochemical mechanism of learning and memory as well. The investigators appear at a loss to explain the similarities between stress-induced and drug-induced VTA changes, but the link may be the theory, of Bessel van der Kolk in Boston and others, that traumatic stress induces a cascade of endogenous opiate release. van der Kolk has long maintained that, in effect, the trauma victim becomes addicted to stress (explaining the risk-taking behaviors and the so-called compulsion to repeat the trauma often seen in this population), and we may be seeing the neurophysiological evidence for it here. Traumatic memory is different from ordinary memory — walled off, experienced inchoately and nonverbally, perhaps repressed; the elucidation of stress-induced changes in a system that regulates learning and memory may help us to understand why.
