We Are Beast Machines – Issue 107: The Edge
I have a childhood memory of looking in the bathroom mirror, and for the first time realizing that my experience at that precise moment—the experience of being me—would at some point come to an end, and that "I" would die. I must have been about 8 or 9 years old, and like all early memories this one too is unreliable. But perhaps it was at this moment that I also realized that if my consciousness

Neuroscience Weighs in on Physics' Biggest Questions – Issue 107: The Edge
For an empirical science, physics can be remarkably dismissive of some of our most basic observations. We see objects existing in definite locations, but the wave nature of matter washes that away. We perceive time to flow, but how could it, really? We feel ourselves to be free agents, and that's just quaint. Physicists like nothing better than to expose our view of the universe as parochial.

The Spiritual Consciousness of Christof Koch – Issue 107: The Edge
Consciousness is a thriving industry. It's not just the meditation retreats and ayahuasca shamans. Or the conferences with a heady mix of philosophers, quantum physicists, and Buddhist monks. Consciousness is a buzzing business in neuroscience labs and brain institutes. But it wasn't always this way. Just a few decades ago, consciousness barely registered as a credible subject for science. Perhap

Solving mystery of rare cancers directly caused by HIV
STAT3 LCK Mystery HIV
•
For nearly a decade, scientists have known that HIV integrates itself into genes in cells that have the potential to cause cancer. And when this happens in animals with other retroviruses, those animals often develop cancer. But, perplexingly and fortunately, that isn't regularly happening in people living with HIV. A new study reveals why doctors aren't seeing high rates of T cell lymphomas — or
