Then there's the new variant that we're not sure of yet.

I think not as I do not think he would have dressed so informally for the Nobel prize in that get up. Funny to think about none the less

Ah! Well at least that is the light at the end of the tunnel in regards to this corona bug. so give it another six months and this bit of human history will but just another page in History book of Humanity.

Davy, I wonder if this is the 3-foot portrait of Tonegawa’s seen "as soon as you walk through the door of the Massachusetts Institute of Technology’s Picower Institute for Learning and Memory?"

Davy. One of the reasons why so many people fear the development of the science of AI is the truly esoteric nature of the subject. But a really interesting subject nevertheless. Thanks, Davy.

Davy, I do not understand how AI can make cars and trucks miss each other on the highway, or the animals that may venture onto the strip of pavement, however, my son, Craig, works on these problems. His language is foreign to me, but his team works on self-driving vehicles, obstructions on the roadway, and he anticipates lives will be saved using this AI.

If the human brain can develop such technology, I am happy I am living to see it. My grandfather brought the first vehicle to our little farming town and I live to see the day of AI and no-human driving. My father lived to see a man walk on the moon. 

The old Chinese curse: "May you live in interesting times," which isn't Chinese nor is it a curse.

A Power Law Keeps the Brain’s Perceptions Balanced

Researchers have discovered a surprising mathematical relationship in the brain’s representations of sensory information, with possible applications to AI research.

A balancing act is not what the scientists initially set out to find. Their work began with a simpler question: Does the visual cortex represent various stimuli with many different response patterns, or does it use similar patterns over and over again? Researchers refer to the neural activity in the latter scenario as low-dimensional: The neural code associated with it would have a very limited vocabulary, but it would also be resilient to small perturbations in sensory inputs.

More on what they have found about our wonderful blob of cells that sit between our ears; but with some it is debatable.{hee hee}

Scientists Say Your “Mind” Isn’t Confined to Your Brain, or Even Your Body

Exploring how the mind extends beyond the physical self.

But what is a mind? Defining the concept is a surprisingly slippery task. The mind is the seat of consciousness, the essence of your being. Without a mind, you cannot be considered meaningfully alive. So what exactly, and where precisely, is it?

Light-Triggered Genes Reveal the Hidden Workings of Memory

Nobel laureate Susumu Tonegawa’s lab is overturning old assumptions about how memories form, how recall works and whether lost memories might be restored from "silent engrams.”

Neuroscientists gained several surprising insights into memory this year, including the discovery that the brain creates multiple copies of memories at once — even though it hides the long-term copy from our awareness at first

Susumu Tonegawa’s presence announces itself as soon as you walk through the door of the Massachusetts Institute of Technology’s Picower Institute for Learning and Memory. A three-foot-high framed photograph of Tonegawa stands front and center in the high-ceilinged lobby, flanked by a screen playing a looping rainbow-hued clip of recent research highlights.
