Chronic Gut Virus May Play a Role in Alzheimer’s Development

Researchers have linked chronic intestinal infections caused by cytomegalovirus (HCMV) to a unique subtype of Alzheimer’s disease. The virus may travel from the gut to the brain via the vagus nerve, altering immune responses and contributing to hallmark Alzheimer’s changes like amyloid plaques and tau tangles. While HCMV infection is common and typically harmless, this study found that it may cause chronic brain inflammation in certain individuals.

Ancient Friendship: Humans and Dogs Bonded 12,000 Years Ago

Humans and canines in the Americas formed close relationships 12,000 years ago, earlier than previously thought. Archaeological findings in Alaska, including a 12,000-year-old canine tibia and an 8,100-year-old jawbone, indicate these animals relied on humans for food, such as salmon, rather than hunting independently.

Herbicide Exposure Linked to Long-Term Brain Inflammation, Alzheimer’s

New research reveals that glyphosate, a widely used herbicide, can cause lasting brain inflammation and accelerate Alzheimer’s-like pathology in mice. Even short-term exposure resulted in persistent inflammatory markers and neurological damage, including anxiety-like behaviors and premature death. The study found that glyphosate’s metabolite, aminomethylphosphonic acid, accumulates in brain tissue, raising concerns about its long-term safety for humans.

Why Human Culture Never Stops Evolving

A new study proposes that human culture’s unique power lies not in its ability to accumulate knowledge, as once thought, but in its "open-endedness." Unlike animal cultures that reach limits in evolution, human culture continuously expands, adapting without bounds.
