Plasticity as a therapeutic target for improving cognition and behavior in Down syndrome

Early intervention and environmental optimization have been central to management of Down syndrome (DS) and much of current treatment is still focused in strategies that involve early education plans. This approach has provided significant improvements for Down syndrome but it is not providing a full success. The discovery of an increasing number of genes and molecular pathways linked to intellectual disability and involving a range of synaptic and plasticity-related mechanisms has open new treatment opportunities that focus on targeted treatments boosting neural plasticity. We here discuss some of these approaches, focusing on the effects of environmental enrichment and on the discovery of pharmacological therapies showing beneficial effects even in some clinical trials in adult individuals with Down syndrome. Targeting plasticity impairments in DS is thus a promising strategy to promote cellular mechanisms involved in learning and memory within key cognitive brain region and could lead to improved connectivity.

A common food compound may hold the key to shutting down leaky gut damage

When the intestinal lining breaks down, harmful gut bacterial antigens can slip into the bloodstream alongside nutrients. This breach in the gut’s protective barrier, known as “leaky gut,” is more than a digestive issue—it’s a sign of inflammatory bowel disease (IBD) and has been increasingly linked to a number of chronic conditions.

A team of researchers working in the lab of UNLV cellular biologist Prasun Guha has uncovered a key mechanism underlying leaky gut and identified a promising and natural way to repair it. And a potential solution is already in many of the foods we eat every day.

In a study published in the journal Nature Communications, the team shares how phytic acid (or InsP6), a natural compound found in whole grains, beans, lentils, nuts, and seeds, plays an important role in maintaining the integrity of the intestinal barrier.

Engineered stem cells reverse new-onset type 1 diabetes in mice

A group of researchers at the Medical University of South Carolina (MUSC) has recently developed a new stem cell therapy with a remarkable ability to reverse new-onset type 1 diabetes (T1D) in a mouse model of the disease. The work is published in the journal Molecular Therapy.

Hongjun Wang, Ph.D., associate director of the South Carolina Clinical & Translational Research (SCTR) Institute Pilot Program and co-scientific director for the Center for Cellular Therapy, led the team. Co-first authors Hua Wei, Ph.D.; Judong Kim, Ph.D.; and Wenyu Gou, Ph.D., together with other collaborators, conducted most of the work to establish these findings.

This research study marks a pivotal move away from the current standard of managing blood sugar through multiple daily insulin injections and toward a lasting way to reprogram the immune system itself. For the millions of people currently living with T1D, this could be a game-changer.

NASA just proved spacecraft can switch between multiple satellite networks

NASA’s PExT terminal has shown that spacecraft can seamlessly communicate through multiple government and commercial networks, a major step beyond traditional single-network systems. The mission is now expanding to test new capabilities that could help create a more flexible, reliable communications infrastructure for future space missions.

China’s Thorium Reactors

Every commercial nuclear reactor in the world runs on uranium. Uranium brings three undeniable problems. It creates weapons-grade plutonium. It melts down under pressure. Its radioactive waste lasts for tens of thousands of years.

Thorium solves all three.
Physicists have known this since the 1960s. The United States actually built a working thorium reactor. They proved the technology was viable. Then they deliberately abandoned it.
