How nanomaterial influences gut microbiome, immune system: Research

Posted by in categories: biotech/medical, health, nanotechnology, wearables

“This shows that we must factor the gut microbiome into our understanding of how nanomaterials affect the immune system,” said the paper’s corresponding author Bengt Fadeel, professor at the Institute of Environmental Medicine, Karolinska Institutet. “Our results are important for identifying the potential adverse effects of nanomaterial and mitigating or preventing such effects in new materials.”

Graphene is an extremely thin material, a million times thinner than a human hair. It comprises a single layer of carbon atoms and is stronger than steel yet flexible, transparent, and electrically conductive. This makes it extremely useful in a multitude of applications, including in “smart” textiles equipped with wearable electronics and as a component of composite materials, to enhance the strength and conductivity of existing materials.

Software lets researchers create tiny rounded objects out of DNA. Here’s why that’s cool

Posted by in categories: biotech/medical, nanotechnology

Marvel at the tiny nanoscale structures emerging from research labs at Duke University and Arizona State University, and it’s easy to imagine you’re browsing a catalog of the world’s smallest pottery.

A new paper reveals some of the teams’ creations: itty-bitty vases, bowls, and hollow spheres, one hidden inside the other, like housewares for a Russian nesting doll.

But instead of making them from wood or clay, the researchers designed these objects out of threadlike molecules of DNA, bent and folded into complex three-dimensional objects with nanometer precision.

New Blood Test Accurately Predicts Alzheimer’s Years Ahead of First Symptoms

Posted by in categories: biotech/medical, neuroscience

A new type of blood test can detect a hidden toxin behind Alzheimer’s disease years before a patient shows any symptoms of memory loss or confusion.

If the proof-of-concept can be further tested and scaled, the test could significantly speed up diagnosis, giving millions of patients answers and access to proper care long before their disease progresses.

Researchers at the University of Washington (UW) created the novel blood test. It’s designed to pick up on a molecular precursor in the blood that can cause proteins to irregularly fold and clump in the brain, ultimately forming amyloid beta (Aβ) plaques.

Gene editing: a new modification moves to human tests

Posted by in categories: bioengineering, biotech/medical

In April 2016, Waseem Qasim, a professor of cell and gene therapy, was intrigued by a new scientific paper that described a revolutionary way to manipulate DNA: basic gene editing. The articlepublished by David Liu’s lab at the Broad Institute of MIT and Harvard, described a version of Crispr gene editing that allowed for more precise changes than ever before.

Our Matrix-like Computational Universe: Programmable Realities & Cybernetic Apotheosis

Posted by in categories: biotech/medical, nanotechnology, neuroscience, robotics/AI, singularity, transhumanism, virtual reality

Do we live in a matrix? Is our universe a metaverse in the next universe up? What is the code of reality? Is this a simulated multiverse? Can we cheat death and live indefinitely long? These are some of the questions we discuss in this recent talk.

Understanding Brain Mechanisms Underpinning Physical Movement and Exercise

Posted by in categories: biotech/medical, health, robotics/AI

Over the last two decades, scientists have postulated several theories that has helped to explain how we acquire motor skills, and the decisions we make in order to execute motor skills to navigate our environment. Additionally, the advent of neuroimaging techniques, such as electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) have contributed significantly to our understanding of movement by providing possible neural correlates and processes that underpin various types of motor function. However, techniques such as EEG and fMRI are highly susceptible to motion artifacts during recording, which limits the range of movements that can be performed during scanning. This limitation impacts on the translational value of such findings in real-world applications.

To overcome the limitations of traditional neuroimaging paradigms, second generation neuroimaging devices such as portable EEG and functional near-infrared spectroscopy (fNIRS), and non-invasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) can be used to study a broader range of dynamic movements and central changes associated with physical exercise. Both EEG and fNIRS can be applied concurrently with a motor task or exercise to understand its associated central response, while the application of non-invasive brain stimulation can help to establish causality by experimentally-induced facilitation or inhibition of specific neural networks.

In this research topic, we aim to showcase recent advances in the use of neuroimaging and non-invasive brain stimulation techniques to understand motor control processes and central adaptations to exercise across the lifespan and disease conditions. Submissions that are Original Research, Systematic Reviews and Meta-analysis, Literature review, Mini-review, Methods, and Perspective articles will be considered. Topics that cover, but not limited to, the following to domains are encouraged:
