The myth of the goldfish’s three second memory has long prevailed in popular culture. However, new research has suggested that unlike humans, fish are able to conserve memories over generations using epigenetic mechanisms. Epigenetic modifications can change the expression of DNA without changing the DNA code itself. Often this is in the form of DNA […]
Alzheimer’s has previously been understood to be caused by a build up of protein plaques in the brain. However, new research has revealed that alternative metabolic pathways in the brain may be more integral to the formation of the disease. The plaques are formed by proteins known as beta-amyloid and tau. As Alzheimer’s progresses the […]
Fruit flies with a certain genetic mutation have significantly longer lifespans and better resistance to stresses than flies without the mutation. Fruit flies share a significant proportion of their genes with humans, making them good models to study human diseases and ageing. As the fruit flies usually live for about two months their lifespan is […]
Cells discontinuing nucleotide synthesis could be a key factor in ageing, new research has revealed. Understanding this process could enable treatments that ensure healthier ageing. The process by which cells become unable to replicate after a certain number of divisions is known as senescence. As cell division is essential the body’s repair processes, senescence can […]
A gene discovery has explained why current Alzheimer’s drugs don’t work for lots of patients, and why so many new drugs fail in clinical trials. The acetylcholine receptor α7nAChR has long been a target of interest for Alzheimer’s drugs. The neurotransmitter acetylcholine is involved in memory and learning processes. Despite acetylcholine being linked to the […]
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 […]
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 […]
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 […]
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 […]
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.
Researchers from the University of Alabama have identified a method by which it is possible to reduce the signs of ageing, such as wrinkles and hair loss, in mice.
Scientists have long thought that regions of DNA called telomeres control how long you live. We are now learning that it is your diet and lifestyle that shape your telomeres, not the other way around.
A small population of brain cells deep in a memory-making region of the brain controls the production of new neurons and may have a role in common brain disorders.
New research presented this week at the Alzheimer’s Association International Conference (AAIC) 2018, is suggesting that the liver could be contributing to Alzheimer’s risk by failing to supply key lipids to the brain.
Researchers at Harvard Medical School have found further evidence that supports the notion that viruses could help cause the onset of Alzheimer’s disease; an idea that was once ridiculed by other sceptics and researchers.
