A weird and brilliantly effective optical illusion that has gone viral on the internet tricks your brain into seeing a color image … but if you look closely you will notice that the photo you are looking at is only black and white.

The viral image was created by artist and developer Øyvind Kolås who carefully overlaid red, orange, yellow, blue, and green grid lines over black and white images.

“An over-saturated coloured grid overlaid on a grayscale image causes the grayscale cells to be perceived as having colour,” Kolås explains on his Patreon page.

The key is an innovation that’s being called ‘light beads microscopy’. It improves on current two-photon microscopy, using lasers to trigger introduced fluorescence in living cells. As the cells are lit up, scientists can see how they’re moving and interacting.

With light beads microscopy, scientists can get the speed, scale, and resolution required to map a mouse brain in detail as its neural activity changes. The near-simultaneous tracking can last for as long as the light beads are able to stay illuminated.

A deepening understanding of the brain has created unprecedented opportunities to alleviate the challenges posed by disability. Scientists and engineers are taking design cues from biology itself to create revolutionary technologies that restore the function of bodies affected by injury, aging, or disease — from prosthetic limbs that effortlessly navigate tricky terrain to digital nervous systems that move the body after a spinal cord injury.

With the establishment of the new K. Lisa Yang Center for Bionics, MIT is pushing forward the development and deployment of enabling technologies that communicate directly with the nervous system to mitigate a broad range of disabilities. The center’s scientists, clinicians, and engineers will work together to create, test, and disseminate bionic technologies that integrate with both the body and mind.

Cardiovascular fat deposition, found to be higher in postmenopausal women compared with premenopausal women, is a novel risk factor for cardiovascular disease. It is also believed to affect cognitive function through neuropathological pathways by changing the secretion of inflammatory cytokines and adipokines. The quality of cardiovascular fat is characterized by its radiodensity.

Summary: Greater radiodensity of perivascular adipose tissue in women during midlife was associated with decreased working memory performance later in life.

A worsening cardiovascular profile after menopause may contribute to the fact that women are disproportionately affected by dementia. A new study identified a link between cardiovascular fat volume and radiodensity and cognitive function, as well as racial differences in this association.

Study results will be presented during The North American Menopause Society (NAMS) Annual Meeting in Washington, DC, September 22–25, 2021.

I believe if superintelligence can be digitized into computer code then essentially a microchip could send electrical impulses to one’s brain noninvasive like the microchip that heals from Ohio state and then superintelligence could be attained and the biological wetware could be easily acquire the biological singularity. Much like the moto that Apple has all things digital a new superintelligence attribute could uploaded and the human could evolve or gene edit from a smartphone also the impulse could be non invasive like low level electrical impulse sending data to the brain using existing hardware. We could be as advanced as any exterrestial civilization in a couple keystrokes using existing hardware.

Popular expectations for the future are helplessly colored by present trends. The assumption is always that whatever’s going on now can be safely extrapolated into the future along a linear (or, per Kurzweil, logarithmic) curve. So it was that during the space race, baby boomers took for granted that we’d have fully colonized the solar system by the year 2000.

Depression is a serious medical condition that plagues modern society. Several theories have been proposed to explain the physiological basis of depression, of which the “neurogenic hypothesis of depression” has garnered much attention.

To use the metaphor of our Information Age, consciousness to humans is as Cloud to computers. Just like your smartphone, your brain is a ‘bio’-logical computing device of your mind, an interface for physical reality. Our minds are connected into the greater mind-network, as computers in the Cloud. Viewed in this way, consciousness is ‘non-local’ Cloud, our brain-mind systems are receivers, processors and transmitters of information within that Cloud. What were the most significant factors in evolution of the human mind? What’s the connection between quantum physics and consciousness? What role does quantum information play in our self-reflective consciousness? What is non-local consciousness? Do our minds create reality? These are some of the most salient questions addressed in this Part II of the documentary.
