Brain’s Hidden Nanotube Network Discovered, May Explain Alzheimer’s Spread

Scientists have discovered a previously unknown network of microscopic tubes in the brain that transport toxic substances between neurons. This finding could fundamentally change our understanding of how Alzheimer’s disease spreads through brain tissue.

Brain’s Secret Transport System Revealed

Researchers at Johns Hopkins Medicine have uncovered what appears to be a hidden highway system within the brain—microscopic tubes that shuttle toxic substances between neurons. According to their recently published study in Science, these nanotube networks might explain both how brain cells clear waste and how Alzheimer’s-related proteins spread throughout the brain.

Human Cells Trigger Self-Destruct Mechanism Against Viral RNA Sabotage, Study Reveals

Human cells can recognize when viruses disrupt RNA production and activate a self-destruction program to prevent viral multiplication, according to a new Nature study. The research reveals how cells transform viral sabotage into defense mechanisms using genetic remnants of ancient infections.

Cellular Self-Destruct Mechanism Activated by Viral RNA Disruption

Human cells possess a sophisticated defense system that triggers self-destruction when viruses disrupt critical RNA production processes, according to a new study published in Nature. The international research team discovered that cells recognize specific viral sabotage tactics and respond with controlled cell death before infections can spread.
