Nicholas Carr's latest article for The Atlantic
posits that automation presents risks, specifically of losing skill and talent. "The lack of awareness and the degradation of know-how raise the odds that when something goes wrong, the operator will react ineptly. The assumption that the human will be the weakest link in the system becomes self-fulfilling."

the oldest brain found. However, there have been other finds and at least one

Our Inconsistent Ethical Instincts
We like to believe that the principled side of the equation is rooted in deep, reasoned conviction. But a growing wealth of research shows that those values often prove to be finicky, inconsistent intuitions, swayed by ethically irrelevant factors. What you say now you might disagree with in five minutes. And such wavering has implications for both public policy and our personal lives. [more inside]

Have you ever been in a room with lots of people and not great ventilation. Or even a room with normal ventilation. You may be cognitively impaired due to elevated levels of CO2 once considered safe now thought enough to make you a little dumb
. 600ppm is now thought too much, but “there are plenty of buildings where you could easily see 2,500 ppm of CO2 — or close to it — even with ventilation designs that are fully compliant with current standards.. classrooms frequently exceed 1,000ppm." [more inside]

"Beyond the Brain" In the 1990s, scientists declared that schizophrenia and other psychiatric illnesses were pure brain disorders that would eventually yield to drugs. Now they are recognizing that social factors are among the causes, and must be part of the cure.

Have you noticed that the first tick after glancing at a clock with a second hand can take more than one second? No, it's not just you! That's a related phenomenon called chronostasis

"...Pam agreed to die in order to save her life—and in the process had what is perhaps the most famous case of independent corroboration of out of body experience (OBE) perceptions on record...Pam later said, she felt herself “pop” out of her body and hover above it, watching as doctors worked on her body. Although she no longer had use of her eyes and ears, she described her observations in terms of her senses and perceptions...with considerable accuracy.

NDE studies [such as these] suggest that after physical death, mind and consciousness may continue in a transcendent level of reality that normally is not accessible to our senses and awareness."
“There are no images and no representations in our minds,” he insisted. “Our visual experience of the world is a continuum between see-er and seen united in a shared process of seeing.”
I was curious, if only because, as a novelist I’d always supposed I was dealing in images, imagery. This stuff might have implications. So we had a beer together
