Does the Universe Have a Purpose? What’s the Point of Universe’s Evolution?

Posted by in categories: computing, cosmology, neuroscience, quantum physics

The Omega Point cosmo-teleology emerges from the intersection of quantum cosmology, teleology, and complex systems theory. Originally conceptualized by French philosopher Pierre Teilhard de Chardin, the Omega Point envisions the universe evolving towards a state of maximum complexity and consciousness (Teilhard de Chardin, 1955). Such a state represents the ultimate goal and culmination of cosmic evolution, wherein the convergence of mind and matter leads to a unified superintelligence.

The Omega Point theory postulates that the universe’s evolution is directed towards increasing complexity and consciousness, a teleological process with a purposeful end goal (Teilhard de Chardin, 1955). The concept was further refined by physicists and cosmologists, including John David Garcia (Garcia, 1996), Paolo Soleri (Soleri, 2001), Terence McKenna (McKenna, 1991), Frank Tipler (Tipler, 1994), and Andrew Strominger (Strominger, 2016).

A complementary perspective to the Omega Point theory is found in the Holographic Principle, which posits that all information within our universe is encoded on its boundary. Such an idea suggests our three-dimensional reality is a projection from this two-dimensional surface (Bekenstein, 2003). In the holographic universe, everything we perceive is a reflection of data encoded at the cosmic edge, which could imply that our entire universe resides within a black hole of a larger universe (Susskind, 1995). This perspective aligns with the concept of maximum informational density at the Omega Point and highlights the profound interconnectedness of all phenomena, blurring the boundaries between mind, matter, and the cosmos into a singular, computational entity.

A maternal brain hormone that builds bone

Posted by in category: neuroscience

Did you know that the nervous system can help to build and repair bone?

Researchers identify a key brain-derived hormone that repairs bone in both sexes and critically maintains bone density in lactating female mice.

Researchers have found that a brain hormone called CCN3, produced by specific…

Putting the Brakes on Chronic Inflammation

Posted by in categories: biotech/medical, health, neuroscience

Scientists at Weill Cornell Medicine discovered a previously unknown link between two key pathways that regulate the immune system in mammals — a finding that impacts our understanding of chronic inflammatory bowel diseases (IBD). This family of disorders severely impacts the health and quality of life of more than 2 million people in the United States.

The immune system has many pathways to protect the body from infection, but sometimes an overactive immune response results in autoimmune diseases including IBD, psoriasis, rheumatoid arthritis and multiple sclerosis. Interleukin-23 (IL-23) is one such immune factor that fights infections but is also implicated in many of these inflammatory diseases. However, it was unknown why IL-23 is sometimes beneficial, and other times becomes a driver of chronic disease.

In the study, published June 12 in Nature, the team found that IL-23 acts on group 3 innate lymphoid cells (ILC3s), a family of immune cells that are a first line of defense in mucosal tissues such as the intestines and lungs. In response, ILC3s increase activity of CTLA-4, a key regulatory factor that prevents the immune system from attacking the body and beneficial gut microbiota. This interaction critically balances the pro-inflammatory effects IL-23 to maintain gut health, but is impaired in IBD.

Erasing ‘bad memories’ to improve long term Parkinson’s disease treatment

Posted by in categories: biotech/medical, neuroscience

Common treatments for Parkinson’s disease can address short-term symptoms, but can also cause extensive problems for patients in the long run. Namely, treatments can cause dyskinesia, a form of uncontrollable movements and postures.

In a recent study published in The Journal of Neuroscience, researchers at the University of Alabama at Birmingham took a different approach to and treated it like a “bad motor memory.” They found that blocking a protein called Activin A could halt dyskinesia symptoms and effectively erase the brain’s “bad memory” response to certain Parkinson’s treatments.

“Instead of looking for a completely alternative treatment, we wanted to see if there was a way to prevent dyskinesia from developing in the first place,” said David Figge, M.D., Ph.D., lead study author and assistant professor in the UAB Department of Pathology. “If dyskinesia does not occur, then patients could potentially stay on their Parkinson’s treatment for longer.”

Run screaming or slow retreat? New study sheds light on brain responses to emotionally-charged scenes

Posted by in categories: food, neuroscience

The ability to recognize and respond to emotionally-charged situations is essential to a species’ evolutionary success. A new study published in Nature Communications advances our understanding of how the brain responds to emotionally charged objects and scenes.

The research, led by Trinity College Dublin neuroscientist Prof. Sonia Bishop, and Google researcher Samy Abdel-Ghaffar while he was a Ph.D. student in Prof. Bishop’s lab at UC Berkeley, has identified how the represents different categories of emotional stimuli in a way that allows for more than a simple “approach/avoid” dichotomy when guiding behavioral responses.

Sonia Bishop, now Chair of Psychology in Trinity’s School of Psychology, and senior author of the paper, explains, It is hugely important for all species to be able to recognize and respond appropriately to emotionally salient stimuli, whether that means not eating rotten food, running from a bear, approaching an attractive person in a bar or comforting a tearful child.

Why did humans evolve big brains? A new idea bodes ill for our future

Posted by in categories: futurism, neuroscience

Recent fossil finds suggest that big brains weren’t an evolutionary asset to our ancestors but evolved by accident – and are likely to shrink again in the near future.

Brain Organoids Communicate: A Step Toward “Organoid Intelligence”

Posted by in categories: genetics, neuroscience

Scientists have connected two organoids together with an axon bundle, to study how brain areas communicate. They sent signals back and forth and responded to external stimulation. This could be a step toward biocomputing.

Learn about: axons, white matter, re-entry, optogenetics, myelination, entrainment, short-term potentiation.
