Australian research links low magnesium levels to increased risk of chronic diseases

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

A new Australian study has identified why a diet rich in magnesium is so important for our health, reducing the risk of DNA damage and chronic degenerative disorders.

Scientists from the University of South Australia measured blood samples from 172 middle aged adults, finding a strong link between low magnesium levels and high amounts of a genotoxic amino acid called homocysteine.

This toxic combination damages the body’s genes, making people more susceptible to Alzheimer’s and Parkinson’s disease, gastrointestinal diseases, a range of cancers, and diabetes.

This researcher wants to replace your brain, little by little

Posted by in categories: government, health, neuroscience

A US agency pursuing moonshot health breakthroughs has hired a researcher advocating an extremely radical plan for defeating death.

His idea?


Scholz is still skeptical though. “A new brain is not going to be a popular item,” he says. “The surgical element of it is going to be very severe, no matter how you slice it.”

Revolutionary Two-Photon Microscope Captures Brain Activity in Real-Time

Posted by in categories: biotech/medical, neuroscience

Researchers have developed a revolutionary two-photon fluorescence microscope that captures neural activity at high speed and cellular resolution, offering unprecedented insights into brain function.

This new approach, which images faster and with less harm to brain tissue than traditional methods, could transform our understanding of how neurons communicate in real-time, potentially leading to breakthroughs in treating neurological diseases like Alzheimer’s and Parkinson’s.

Sleep resets neurons for new memories the next day, study finds

Posted by in category: neuroscience

While everyone knows that a good night’s sleep restores energy, a new Cornell University study finds it resets another vital function: memory.

Learning or experiencing new things activates neurons in the hippocampus, a region of the vital for memory. Later, while we sleep, those same neurons repeat the same pattern of activity, which is how the brain consolidates those memories that are then stored in a large area called the cortex. But how is it that we can keep learning new things for a lifetime without using up all of our neurons?

A study, “A Hippocampal Circuit Mechanism to Balance Memory Reactivation During Sleep,” published in Science, finds at certain times during , certain parts of the hippocampus go silent, allowing those neurons to reset.

The brain creates parallel copies for a single memory, new study reveals

Posted by in categories: futurism, neuroscience

A new study now published in Science reveals that the memory for a specific experience is stored in multiple parallel “copies.” These are preserved for varying durations, modified to certain degrees, and sometimes deleted over time, report researchers at the University of Basel.

The ability to turn experiences into memories allows us to learn from the past and use what we learned as a model to respond appropriately to new situations. For this reason, as the world around us changes, this memory model cannot simply be a fixed archive of the good old days.

Rather, it must be dynamic, changing over and adapting to new circumstances to better help us predict the future and select the best course of action. How the could regulate a memory’s dynamics was a mystery—until multiple memory copies were discovered.

Who Knows What Consciousness Is?

Posted by in categories: biotech/medical, neuroscience, quantum physics

At the risk of sounding a bit woo-woo, as any speculation about the “hard problem” of the unknowns of consciousness does, can’t both be true? In other words, is it possible that Schrödinger’s “total mind” is a kind of quantum reserve downloaded and differentially phased into qualia through the materialist medium of natural selection, which Edelman calls “neural Darwinism”? Is it the embodied human sensory organs interacting with their environment in feedback loops that unveils the unformed wave of fundamental consciousness through the particle of particular experience?

The correct answer is: Who knows?

“Who Knows?” would be an apt title for the best inventory to date of the myriad views on consciousness, from the metaphysical to the materialist, compiled by Robert Lawrence Kuhn and titled “A landscape of consciousness: toward a taxonomy of explanations and implications,” recently published in the journal “Progress in Biophysics and Molecular Biology.”

Common drug restores youthful function to clean up aging brains

Posted by in categories: biotech/medical, life extension, neuroscience

First described by Nedergaard and her colleagues in 2012, the glymphatic system is the brain’s unique waste removal process that uses cerebrospinal fluid (CSF) to wash away excess proteins generated by energy hungry neurons and other cells in the brain during normal activity.


A drug used to induce labor in pregnant women has been shown to reactivate tiny waste-clearing pumps in the brains of old mice. The finding could hold promise as a new way to fight Alzheimer’s and Parkinson’s diseases and overall cognitive decline.

When our brains are working properly, there is an excess of proteins that build up from the energy intensive processes that take place between our neurons. Those proteins need to be removed in order for the brain to continue to operate properly. When they aren’t, they can gunk up the works, leading to the beta amyloid and tau protein tangles that are a hallmark of Alzheimer’s disease or the build up of alpha-synuclein that accompanies Parkinson’s.

“Virtual Reality Is GENUINE Reality“ | David Chalmers Mindfest Lecture

Posted by in categories: neuroscience, virtual reality

Philosopher and cognitive scientist David Chalmers explores virtual reality and its implication for our understanding of existence. Chalmers examines the simulation hypothesis, challenging conventional views of reality and suggesting that virtual worlds might be as real and meaningful as the physical world. This is a thought-provoking lecture at MindFest, held at Florida Atlantic University, CENTER FOR THE FUTURE MIND, spearheaded by Susan Schneider.
