Media Circus Surrounds Hyperbaric Oxygen Study

Posted by in categories: life extension, neuroscience

Important that people read this given how much this spread.


If you have been following the mainstream media recently, you have probably seen a story about hyperbaric oxygen treatment and claims that it can reverse aging. Unfortunately, the media hype surrounding the results is nothing like the reality of the actual research paper, and this is another example of how shoddy journalism harms our field.

Welcome to the media circus

Scientists Create Electronic Gadget Powered by Quantum Tunneling

Tiny Dancer

Chakrabartty’s tunneling barrier was built in just such a way that “you can control the flow of electrons. You can make it reasonably slow, down to one electron every minute and still keep it reliable.”

The team is hoping the technology could one day power glucose or even brain activity monitors without the need for batteries.

Microfluidic Brain-on-a-Chip: Perspectives for Mimicking Neural System Disorders

Posted by in categories: biotech/medical, chemistry, computing, neuroscience

Neurodegenerative diseases (NDDs) include more than 600 types of nervous system disorders in humans that impact tens of millions of people worldwide. Estimates by the World Health Organization (WHO) suggest NDDs will increase by nearly 50% by 2030. Hence, development of advanced models for research on NDDs is needed to explore new therapeutic strategies and explore the pathogenesis of these disorders. Different approaches have been deployed in order to investigate nervous system disorders, including two-and three-dimensional (2D and 3D) cell cultures and animal models. However, these models have limitations, such as lacking cellular tension, fluid shear stress, and compression analysis; thus, studying the biochemical effects of therapeutic molecules on the biophysiological interactions of cells, tissues, and organs is problematic. The microfluidic “organ-on-a-chip” is an inexpensive and rapid analytical technology to create an effective tool for manipulation, monitoring, and assessment of cells, and investigating drug discovery, which enables the culture of various cells in a small amount of fluid (10−9 to 10−18 L). Thus, these chips have the ability to overcome the mentioned restrictions of 2D and 3D cell cultures, as well as animal models. Stem cells (SCs), particularly neural stem cells (NSCs), induced pluripotent stem cells (iPSCs), and embryonic stem cells (ESCs) have the capability to give rise to various neural system cells. Hence, microfluidic organ-on-a-chip and SCs can be used as potential research tools to study the treatment of central nervous system (CNS) and peripheral nervous system (PNS) disorders. Accordingly, in the present review, we discuss the latest progress in microfluidic brain-on-a-chip as a powerful and advanced technology that can be used in basic studies to investigate normal and abnormal functions of the nervous system.

Researchers improve neuronal reprogramming

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

The replacement of lost neurons is a holy grail for neuroscience. A new promising approach is the conversion of glial cells into new neurons. Improving the efficiency of this conversion or reprogramming after brain injury is an important step towards developing reliable regenerative medicine therapies. Researchers at Helmholtz Zentrum München and Ludwig Maximilians University Munich (LMU) have identified a hurdle towards an efficient conversion: the cell metabolism. By expressing neuron-enriched mitochondrial proteins at an early stage of the direct reprogramming process, the researchers achieved a four times higher conversion rate and simultaneously increased the speed of reprogramming.

Neurons (nerve cells) have very important functions in the brain such as information processing. Many brain diseases, injuries and neurodegenerative processes, are characterized by the loss of neurons that are not replaced. Approaches in regenerative medicine therefore aim to reconstitute the neurons by transplantation, stem cell differentiation or direct conversion of endogenous non-neuronal cell types into functional neurons.

Researchers at Helmholtz Zentrum München and LMU are pioneering the field of direct conversion of glial cells into neurons which they have originally discovered. Glia are the most abundant cell type in the brain and can proliferate upon injury. Currently, researchers are able to convert glia cells into neurons — but during the process many cells die. This means that only few glial cells convert into functional nerve cells, making the process inefficient.

3 Profound Impacts Exercise Has on The Brain

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

Here are just a few ways exercise changes the structure of our brain.

Memory

Many studies suggest that exercise can help protect our memory as we age. This is because exercise has been shown to prevent the loss of total brain volume (which can lead to lower cognitive function), as well as preventing shrinkage in specific brain regions associated with memory. For example, one magnetic resonance imaging (MRI) scan study revealed that in older adults, six months of exercise training increases brain volume.

Brain Scientists Explore the How of When

Posted by in categories: biotech/medical, neuroscience

Merriam-Webster’s defines a time warp as a “discontinuity, suspension or anomaly” in the otherwise normal passage of time; this year all three terms could apply. It seems like March happened 10 years ago; everyday may as well be Wednesday, and still, somehow, here come the holidays — fast, just like every year.

Some bard or novelist may yet come forth to help explain the paradoxes of pandemic time, both its Groundhog Days and the blurs of stress and fear for those on the front lines, or who had infectious people in their household. But brain science also has something to say about the relationship between perceived time and the Greenwich Mean variety, and why the two may slip out of sync.

In a new study, a research team based in Dallas reported the first strong evidence to date of so-called “time cells” in the human brain. The finding, posted by the journal PNAS, was not unexpected: In recent years, several research groups have isolated neurons in rodents that track time intervals. It’s where the scientists look for these cells, and how they identified them, that provide some insight into the subjective experiences of time.
