Species Lifespan Predicted by Rate of Telomere Shortening

New research has indicated that a species’ lifespan can be predicted by the rate of telomere shortening but not by the initial telomere length, as previously thought. Telomeres are repetitive sequences of DNA nucleotides found at the end of chromosomes. They protect the chromosome from degradation during cell division. As species age, the length of […]

Alzheimer’s-Linked Gene Could be Re-shuffling its Own DNA

APP, the gene responsible for making beta-amyloid in the brain, may be able to reshuffle its own DNA, scientists from Sanford Burnham Prebys Medical Discovery Institute in California have claimed. This development could explain why most drugs to treat Alzheimer’s, which are designed to remove beta-amyloid protein build-ups in the brain, have proven ineffective in clinical trials.
