DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Melatonin as a safe and potentially life-saving treatment for COVID-19

A new study discusses the possible role of melatonin, an antioxidant and anti-inflammatory agent, in treating COVID-19.

New stem cell model could help map out the key genomic changes during early development

Researchers from the Babraham Institute have today published their latest work in the journal Cell Stem Cell describing a new subset of human embryonic stem cells that closely resemble the cells present at the genomic 'wake up call' of the 8-cell embryo stage in humans.

Study provides a promising new avenue for development of anti-obesity treatments

An anti-tumor drug promotes weight loss in mice at low doses by activating a natural hunger-suppressing pathway, according to a new study publishing February 24th in the open-access journal PLOS Biology by Jiang Wei Wu and colleagues at Northwest A&F University in Shaanxi, China.

Research reveals why a common genetic variant worsens outcomes for people with ALS and FTD

A pioneering new study led by UCL and National Institutes of Health (NIH) scientists has revealed, for the first time, why a common genetic variant worsens disease outcomes for people with the devastating adult-onset neurodegenerative diseases amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).

Study shows how certain RNA molecules control the repair of damaged DNA in cancer cells

A new study from Karolinska Institutet in Sweden shows how certain RNA molecules control the repair of damaged DNA in cancer cells, a discovery that could eventually give rise to better cancer treatments. The study is published today in the journal Nature Communications.
