Though some computer engineers claim to know what human consciousness is, many neuroscientists say that we’re nowhere close to understanding what it is — or its source.
In this video, bestselling author Douglas Rushkoff gives the “transhumanist myth” — the belief that A.I. will replace humans — a reality check. Is it hubristic to upload people’s minds to silicon chips, or re-create their consciousness with algorithms, when we still know so little about what it means to be human?
You can read more about Rushkoff’s perspective on this issue in his new book, Team Human.

The thing that Carl Sagan did better than anybody else was connecting to the science through emotion and stories, says NASA’s Michelle Thaller. Watching him when growing up formed Thaller’s vision of what an astronomer could be and inspired her for the rest of her life.

Restless rapid eye movement (REM) sleep impedes emotional processing, which may contribute to mood and anxiety disorders, new research suggests.
A team of Dutch investigators used fMRI to scan the brains of participants who underwent a stressful experience — in this case, hearing themselves sing out of tune. Brain activity was measured using electroencephalography (EEG).
The next morning, after spending the night in a sleep laboratory, participants were subjected to the same unpleasant experience. Those who had experienced REM sleep were less distressed, whereas those with restless REM sleep were once again upset.
