A recent study reveals that both newborns and Alzheimer's patients have elevated levels of the brain protein p-tau217, which plays different roles in each group—supporting healthy brain development in infants and indicating neurodegeneration in Alzheimer's. The findings suggest that understanding how the healthy brain manages tau could lead to new treatments for Alzheimer's disease.

A study suggests that a parasitic, egg-eating worm found on female blue crabs in Chesapeake Bay could serve as a biomarker for their reproductive history, helping to manage and potentially rebuild crab populations by identifying spawning females and understanding reproductive patterns, especially in low-salinity conditions.

A study found that newborns and Alzheimer's patients both have elevated levels of the biomarker p-tau217, but in newborns, this protein supports healthy brain development, whereas in Alzheimer's it is associated with disease progression. The findings suggest potential pathways for new treatments by understanding how the healthy brain regulates tau protein.

A recent study challenges the idea that taurine levels decline with age or serve as a reliable biomarker for aging, showing that taurine levels generally stay stable or increase across adulthood, and emphasizing the need for further research before considering taurine supplements as anti-aging treatments.

A recent study by the NIH found no evidence that taurine levels decline with age in humans, mice, or monkeys, challenging the idea that taurine supplements can promote healthy aging. While earlier animal studies suggested potential benefits, the new research indicates taurine is unlikely to be a reliable biomarker for aging, and more clinical trials are needed before recommending supplementation for age-related health improvements.
