Now, scientists have a mathematical model that closely matches how the human brain processes visual information.

Scientists have confirmed that human brains are naturally wired to perform advanced calculations, much like a high-powered computer, to make sense of the world through a process known as Bayesian inference.

In a study published in the journal Nature Communications, researchers from the University of Sydney, University of Queensland and University of Cambridge developed a specific mathematical model that closely matches how human brains work when it comes to reading vision. The model contained everything needed to carry out Bayesian inference.

In an age of unpredictable job evolution, it is hard to argue that the knowledge acquisition historically associated with a university degree is still relevant. But as university qualifications become more commonplace, recruiters and employers will increasingly demand them, regardless of whether they are actually required for a specific job. Research shows that the correlation between education level and job performance is weak, and that intelligence scores are a much better indicator of job potential. If we were to pick between a candidate with a college degree and a candidate with a higher intelligence score, we could expect the latter to outperform the former in most jobs, particularly when those jobs require constant thinking and learning.

Insights into healing and aging were discovered by National Institutes of Health researchers and their collaborators, who studied how a tiny sea creature regenerates an entire new body from only its mouth. The researchers sequenced RNA from Hydractinia symbiolongicarpus, a small, tube-shaped animal that lives on the shells of hermit crabs. Just as the Hydractinia were beginning to regenerate new bodies, the researchers detected a molecular signature associated with the biological process of aging, also known as senescence. According to the study published in Cell Reports, Hydractinia demonstrates that the fundamental biological processes of healing and aging are intertwined, providing new perspective on how aging evolved.

NIH researchers researchers and collaborators have gained some key insights into the biological inner-workings of regrowing a body, the evolution of aging and a unique method to dispose of aging cells, by studying the genomes of a hermit crab (Hydractinia symbiolongicarpus).

Professor Geoff Duller from Aberystwyth University explained that, given the considerable age of these artifacts, assigning precise dates to them presented a significant challenge. To address this issue, luminescence dating techniques were employed. These innovative dating methods have broad-ranging implications, enabling the dating of much older materials and facilitating the reconstruction of sites that offer insights into human evolution—in the case of Kalambo Falls, an excavation conducted in the 1960s yielded comparable wooden fragments. Still, their dating had remained elusive, leaving the true importance of the site uncertain until now.

Kalambo Falls is located on the Kalambo River above a 772-foot (235-meter) waterfall on the border of Zambia and Tanzania near Lake Tanganyika. The area is on a ‘tentative ‘list from UNESCO for becoming a World Heritage site because of its archaeological significance.

There is powerful science behind how our beliefs inform our genetic expression. It’s not our genes alone that dictate our health outcomes, rather it’s the biology of belief that determines our destiny.

Today on The Doctor’s Farmacy, I’m excited to talk to Dr. Bruce Lipton about how exactly our thoughts determine our genetic expression, and how we can influence our health using our minds.

Dr. Bruce Lipton is a stem cell biologist and author of the bestselling books, The Biology of Belief, Spontaneous Evolution, and The Honeymoon Effect. Dr. Lipton is the recipient of the prestigious Japanese Goi Peace Award and has been listed in the top 100 of “the world’s most spiritually influential people” by Briton’s Watkins Journal for the last 13 years.

A study in the journal Cell sheds new light on the evolution of neurons, focusing on the placozoans, a millimeter-sized marine animal. Researchers at the Center for Genomic Regulation in Barcelona find evidence that specialized secretory cells found in these unique and ancient creatures may have given rise to neurons in more complex animals.

Placozoans are tiny animals, around the size of a large grain of sand, which graze on algae and microbes living on the surface of rocks and other substrates found in shallow, warm seas. The blob-like and pancake-shaped creatures are so simple that they live without any body parts or organs.

These animals, thought to have first appeared on Earth around 800 million years ago, are one of the five main lineages of animals alongside Ctenophora (), Porifera (sponges), Cnidaria (corals, sea anemones and jellyfish) and Bilateria (all other animals).

Our current theory of evolution holds that all life on Earth originated from a single, simple life form billions of years ago. But what if that life did not originate on Earth? In this episode we’ll explore the theory of Panspermia, that origin of life might be extraterrestrial in origin, and that the abiogenesis of that origin life form we descend from might have descended from the sky in a comet or some other alien source. We will explore the impact this concept would have on the Fermi Paradox if true.

Research led by the Department of Anthropology and School of Biomedical Sciences, Kent State University, Ohio, has investigated neuropeptide Y innervation in an area of the brain called the nucleus accumbens of various primate species, including humans. The research was focused on understanding its role in brain evolution and any implications for human health, particularly regarding addiction and eating disorders.

In a paper, “Hedonic eating, obesity, and addiction result from increased neuropeptide Y in the nucleus accumbens during human ,” published in PNAS, the researchers suggest that the combination of increased neuropeptide Y (NPY) and dopamine (DA) within the human nucleus accumbens (NAc) may have allowed for enhanced . This same configuration may have also made humans exceptionally vulnerable to eating disorders and , hinting at addictive traits having a deep evolutionary origin.

NPY plays a role in the reward system, emotional behavior and is associated with increased alcohol use, drug addiction and . The NAc brain region is central to motivation and action, exhibiting one of the highest densities of NPY in the brain and is of great interest to researchers investigating brain-related promoters of addiction.
