Study discovers new subset of retinal neurons impacting vision

Posted by in categories: biotech/medical, neuroscience

Investigators have discovered a new subtype of interneurons in the retina that allows the eye to see and identify objects better in both the light and in the dark, according to a Northwestern Medicine study published in Nature Communications.

The findings dismantle previous notions about the inner workings of the eye and also have broader implications for informing future neuroscience research, according to Yongling Zhu, Ph.D., assistant professor of Ophthalmology, of Neuroscience and senior author of the study.

In a mammalian eye, the retina converts light into that the then sends to the brain, enabling vision. Before being transmitted to the brain, the electrical signals are processed in a dense, synaptic layer within the retina, which is divided into two halves.

Diabetes: AI and 10-second voice recording may aid diagnosis

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

Currently, the most common and accurate methods for diagnosing type 2 diabetes involve blood work. A new study, however, asserts that type 2 diabetes can now be diagnosed based on the sound of a person’s voice.

Researchers from Klick Applied Science have developed a tool they say can diagnose type 2 diabetes in women and men, respectively, with up to 0.89 and 0.86 accuracy.

To achieve this, the researchers used an ensemble model that also factored in women’s body mass index (BMI) and men’s age and BMI.

A SRI newsletter with 2 titles, 23 October 2023

Posted by in categories: governance, space

The SRI President Bernard Foing and the SRI CEO and Founder A. V. Autino are in agreement on the text of this newsletter, but not on the title(!). We decided therefore to issue it with two titles. The first one, by A.V. Autino, establishes an ideological distance from the governance model that brought the civilization to the current situation, refusing any direct co-responsibility. The title proposed by B. Foing implies that “we” (the global society) are responsible for the general failure since we voted for the current leaders. He also suggested that should “we” (space humanists) be governing, he’s not sure that we would be able to do better than current leaders, for peace and development. Better than warmongers for sure! Replied Autino. However, both titles are true and have their reasons. That’s why we don’t want to choose one…

Microbial Cross-Feeding Scores Uncover Interactions That Influence Gut Health

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

An international research team led by scientists at the Hudson Institute of Medical Research has found a way to determine which species of gut microbiota are important in certain diseases, and how they interact with other microorganisms to create a healthy microbiome.

The team developed a computational metabolite exchange scoring system to identify microbial cross feeding relationships—the use of metabolites produced by one microorganism as an essential nutrients by another—and how these may be altered in disease. The researchers suggest that understanding such relationships could point to therapeutic approaches for a range of disorders including inflammatory bowel disease, infections, autoimmune diseases and cancer.

“There are roughly 1,000 different bacterial species in a healthy gut—it’s a microscopic multicultural community with over a trillion individual members,” said research lead Samuel Forster, PhD. “Bacteria in our microbiomes exist as communities that rely on each other to produce and share key nutrients between them … We have developed a new computational way to understand these dependencies and their role in shaping our microbiome. This new method unlocks our understanding of the gut microbiome and provides a foundation for new treatment options that selectively remodel microbial communities.”

Brain Power Renewed: A Biomarker’s Predictive Magic on Neuron Regeneration

Posted by in category: neuroscience

Findings could help scientists develop regenerative therapies for spinal cord injuries and other neurological conditions.

Neurons, the main cells that make up our brain and spinal cord, are among the slowest cells to regenerate after an injury, and many neurons fail to regenerate entirely. While scientists have made progress in understanding neuronal regeneration, it remains unknown why some neurons regenerate and others do not.

Using single-cell RNA.
