Scientists develop blueprint for turning stem cells into sensory interneurons

Researchers at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have developed a first-of-its-kind roadmap detailing how stem cells become sensory interneurons—the cells that enable sensations like touch, pain and itch.

The study, conducted using embryonic stem cells from mice, also identified a method for producing all types of sensory interneurons in the laboratory.

Ageless Biomarkers & Diagnostics Companies

Ageless biomarkers and diagnostics company overview.

So proud of fellow Ageless Partners® coach Kamila Issabayeva for giving such an excellent overview of all the different Biomarkers currently on the market. Also, I had the pleasure of being a co-moderator together with Jason C. Mercurio of this wonderful intellectual presentation.

She talks about the ideal Aging biomarker panel, pricing, accuracy and which tests have the highest correlation Aging.

A highly informative presentation that you would not want to miss!

Grandparents may hold a surprising evolutionary benefit — sparked

It’s all about a mutation of genome. Researchers from the University of California San Diego School of Medicine have discovered a set of human gene mutations that prevent cognitive decline and dementia in older adults, according to a new study published on July 9, 2022, in the journal Molecular Biology and Evolution. The scientists focused on one of the mutated genes and traced its evolution through its appearance in the human genome.

Synchron says it’s the first to implant a human brain-computer interface in the US

Brain-computer interfaces have become a practical (if limited) reality in the US. Synchron says it has become the first in the country to implant a BCI in a human patient. Doctors in New York’s Mount Sinai West implanted the company’s Stentrode in the motor cortex of a participant in Synchron’s COMMAND trial, which aims to gauge the usefulness and safety of BCIs for providing hands-free device control to people with severe paralysis. Ideally, technology like Stentrode will offer independence to people who want to email, text and otherwise handle digital tasks that others take for granted.

Surgeons installed the implant using an endovascular procedure that avoids the intrusiveness of open-brain surgery by going through the jugular vein. The operation went “extremely well” and let the patient return home 48 hours later, according to Synchron. An ongoing Australian trial has also proven successful so far, with four patients still safe a year after receiving their implants.

It may take a long time before doctors can offer Synchron’s BCIs to patients. The company received FDA approval for human trials in July 2021, and it’s still expanding the COMMAND trial as of this writing. Still, the US procedure represents a significant step toward greater autonomy for people with paralysis. It also represents a competitive victory — Elon Musk’s Neuralink has yet to receive FDA permission for its own implant.

A Blueprint for Turning Stem Cells Into Sensory Interneurons

Summary: Researchers have created a new blueprint that outlines how embryonic stem cells from mice become sensory interneurons and identified a method for producing sensory interneurons in a lab setting. If the results can be replicated in human stem cells, researchers say the findings could contribute to the development of therapies to restore sensation to those suffering nerve damage and spinal cord injury.

The missing links: Finding function in lincRNAs

Genomes contain regions between protein-coding genes that produce lengthy RNA molecules that never give rise to a protein. These long intergenic non-coding RNAs (lincRNAs) are thought to have important functions, such as regulating responses to environmental change. However, a paucity of well-annotated lincRNA data, especially for crop plants, has precluded a deeper understanding of their roles.

Up until now, there have been no systematic genome-wide studies that both confirmed DNA sequences that produce lincRNAs and proposed functions for those lincRNAs. Plus, data are reported differently across studies, making direct comparisons among them difficult.

These barriers inspired researchers at the Boyce Thompson Institute to take a comprehensive look at the identity, production and function of lincRNAs in four species in the mustard family, including the model organism Arabidopsis thaliana, and Brassica rapa, a species that produces boy choy, turnips and other .

Failures in large networks can be prevented with local focus

We live in an increasingly connected world, a fact underscored by the swift spread of the coronavirus around the globe. Underlying this connectivity are complex networks—global air transportation, the internet, power grids, financial systems and ecological networks, to name just a few. The need to ensure the proper functioning of these systems also is increasing, but control is difficult.

Now a Northwestern University research team has discovered a ubiquitous property of a complex network and developed a novel computational method that is the first to systematically exploit that property to control the whole network using only . The method considers the computational time and information communication costs to produce the optimal choice.

The same connections that provide functionality in networks also can serve as conduits for the propagation of failures and instabilities. In such dynamic networks, gathering and processing all the information necessary to make a better decision can take too much time. The goal is to diagnose a problem and take action before it leads to a system-wide issue. This may mean having less information but being timely.
