Epigenetics

The study of non genetic heritability. Epigenetics can have an incredible phenotypic effect, and the study of epigenetic factors and mechanisms is an exciting and developing field.

Fish Can Conserve Memories Across Generations

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 […]

Science of Gender-Swapping Fish Revealed

New research has explored the dynamic genetic changes taking place during the bluehead wrasse’s sex change. The bluehead wrasse social group consists of one dominant blue male fish and a harem of yellow females. However, when the dominant male is removed from the group the largest female immediately undergoes a full sex change and becomes […]

Effects of Poverty Make Their Mark on 1,500 Genes in the Body

A study conducted by Northwestern University researchers has found that long-term poverty can be “embedded” across the genome. Lower socioeconomic status was found to be associated with levels of DNA methylation, a key epigenetic mark that can influence expression, across more than 1,500 genes.

A New Approach To Detecting Cancer Earlier From Blood Tests

Cancer scientists led by principal investigator Dr. Daniel De Carvalho at Princess Margaret Cancer Centre have combined “liquid biopsy,” epigenetic alterations and machine learning to develop a blood test to detect and classify cancer at its earliest stages.
