RNA Key to Anti-Ageing Skincare

Scientists have found that RNA production is behind the regenerative affects of laser skincare treatments. Laser treatments are a widespread cosmetic procedure to make skin appear younger and healthier. The laser slightly damages the skin cells, forcing them to repair themselves. After the repair process, the skin looks younger, but until recently the mechanism to […]

Healthy Lifestyle can Reduce Genetic Risk for Dementia

A study has shown that you can reduce your risk of getting dementia by adapting a healthy lifestyle, regardless of your genetic pre-disposition. Genetic factors can increase a person’s likelihood of getting dementia, but until now it was not known if making lifestyle changes could reduce this risk. 196,383 individuals above 60 years of age […]

New Gene Linked to Healthy Ageing in Worms

A gene has been identified in worms that improves their health, but not their lifespan, as they age. Maintaining quality of life is becoming a focus in healthcare for the elderly, as people that live to the same age do not necessarily have the same quality of life. Some maintain both their movement and cognitive […]

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.
