Data from Coinshares underscores the wealth from days gone by which will ultimately fall into the hands of those who are sympathetic to Bitcoin as sound money.
Those who consider Bitcoin sound money will benefit from Baby Boomers to the tune of three times of U.S. GDP.
As you read this line, you’re bringing each word into clear view for a brief moment while blurring out the rest, perhaps even ignoring the roar of a leaf blower outside. It may seem like a trivial skill, but it’s actually fundamental to almost everything we do. If the brain weren’t able to pick and choose what portion of the incoming flood of sensory information should get premium processing, the world would look like utter chaos—an incomprehensible soup of attention-hijacking sounds and sights.
Meticulous research over decades has found that the control of this vital ability, called selective attention, belongs to a handful of areas in the brain’s parietal and frontal lobes. Now a new study suggests that another area in an unlikely location—the temporal lobe—also steers the spotlight of attention.
The unexpected addition raises new questions in what has long been considered a settled scientific field. “The last time an attention controlling area was discovered was 30 years ago,” says Winrich Freiwald, head of Rockefeller’s Laboratory of Neural Systems, who published the findings in the Proceedings of the National Academy of Sciences on November 4, 2019, “This is a fundamental discovery that might require a rethinking of old concepts about attentional control.”

If you’re interested in mind uploading, I have a book that I highly recommend. Rethinking Consciousness is a book by Michael S. A. Graziano, who is a Princeton University professor of psychology and neuroscience.
Early in his book Graziano writes a short summary:
“This book, however, is written entirely for the general reader. In it, I attempt to spell out, as simply and clearly as possible, a promising scientific theory of consciousness — one that can apply equally to biological brains and artificial machines.”

Cardiorespiratory exercise—walking briskly, running, biking and just about any other exercise that gets your heart pumping—is good for your body, but can it also slow cognitive changes in your brain?
A study in Mayo Clinic Proceedings from the German Center for Neurodegenerative Diseases provides new evidence of an association between cardiorespiratory fitness and brain health, particularly in gray matter and total brain volume—regions of the brain involved with cognitive decline and aging.
Brain tissue is made up of gray matter and filaments called white matter that extend from the gray matter cells. The volume of gray matter appears to correlate with various skills and cognitive abilities. The researchers found that increases in peak oxygen uptake are strongly associated with increased gray matter volume.
“Brain activity synchronizes with sound waves, even without audible sound, through lip-reading, according to new research published in JNeurosci.”

Nothing lasts forever. Humans, planets, stars, galaxies, maybe even the Universe itself, everything has an expiration date. But things in the quantum realm don’t always follow the rules. Scientists have found that quasiparticles in quantum systems could be effectively immortal.
That doesn’t mean they don’t decay, which is reassuring. But once these quasiparticles have decayed, they are able to reorganise themselves back into existence, possibly ad infinitum.
This seemingly flies right in the face of the second law of thermodynamics, which asserts that entropy in an isolated system can only move in an increasing direction: things can only break down, not build back up again.
