Researchers have developed an epigenetic clock, "Retro-Age," that predicts biological age by analyzing DNA markers from ancient viral remnants in the human genome. This study highlights how the reactivation of these retroelements, such as HERVs and LINEs, impacts aging, inflammation, and genomic stability. The findings suggest that monitoring these markers could guide anti-aging therapies and improve health outcomes, particularly in conditions like HIV. The research also opens avenues for exploring treatments that may reverse the biological effects of aging.

Summary: During sleep, the brain resets memory by silencing specific neurons in the hippocampus, allowing for continuous learning without overloading. This process, crucial for memory consolidation, involves different regions of the hippocampus, particularly CA2, which helps reset memory circuits. Researchers believe this mechanism could be used to enhance memory or potentially erase traumatic memories. The study provides insight into why sleep is vital for maintaining cognitive function and memory. Key Facts: Source: Cornell University While everyone knows that a good […]

Increasing knowledge can lead to negative outcomes when individuals use it for self-interest rather than collective good. Researchers argue that enhanced knowledge can reduce cooperation among rational individuals, potentially worsening overall welfare.

Researchers used machine learning to identify three subtypes of Parkinson’s disease based on progression speed. These subtypes, marked by distinct genetic drivers, could enhance diagnosis and treatment strategies.
