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).

Woman who does not feel pain

A woman has been identified by doctors to be able to withstand pain. Surgeons were surprised to encounter her when they noticed that she made a completely painless recovery after a surgery.

New strategy for potential treatment of HBV associated liver cancer

Researchers from Duke-NUS Medical School, Singapore General Hospital and Lion TCR have demonstrated that they were able to engineer HBV-specific T cells, a type of immune cells found in the body, to treat Hepatocellular carcinoma, a commonly occurring liver cancer.

Sepsis research in quest for treatments focuses on role of genes

Scientists say the study could help identify those most vulnerable to sepsis, which kills more than 50,000 people in the UK each year and is the leading preventable cause of death worldwide.

Garvan researchers develop more accurate method to diagnose cancer subtypes

Developed by researchers at the Garvan Institute of Medical Research, this potential diagnostic method screens a cancer sample for 'fusion genes', estimated to be linked to one in five cancers, and may provide a more accurate snapshot of rearranged DNA found in cancer.

Horizon Discovery partners with St George’s University Hospital and EMQN to develop reference material for NIPT

Horizon Discovery Group plc, a global leader in gene editing and gene modulation technologies, today announced it is collaborating with St George’s University Hospital, London, and the European Molecular Genetics Quality Network (EMQN), based within the Manchester Centre for Genomic Medicine at Saint Mary’s Hospital, to develop reference material for non-invasive prenatal testing (NIPT).

Researchers find little evidence for connection between Chinese Famine and T2DM epidemic

The Chinese Famine of 1959-61 has been widely interpreted as an important contributor to later epidemics of Type 2 Diabetes Mellitis, but in re-examining 17 related Chinese studies researchers at Columbia University Mailman School of Public Health and Leiden University Medical Center, found little evidence for this association.

Synthetic biological logic gate could one day be used to modify cellular function

Genes in living cells are activated - or not - by proteins called transcription factors. The mechanisms by which these proteins activate certain genes and deactivate others play a fundamental role in many biological processes.

Higher levels of sex hormones in older men related to lower biological age

Older men tend to have lower biological age if they have higher levels of sex hormones, particularly the estradiol form of estrogen, a large new study from Australia finds.

Bacteria may travel thousands of miles through the air worldwide, Rutgers study suggests

Bacteria may travel thousands of miles through the air worldwide instead of hitching rides with people and animals, according to Rutgers and other scientists. Their "air bridge" hypothesis could shed light on how harmful bacteria share antibiotic resistance genes.

Immune system errors linked to development of childhood leukemia

Genetic mutations that drive the development of a common type of childhood leukemia can be traced back to errors by the immune system during the production of antibodies.

Recurrent pregnancy loss may be caused by sperm DNA damage, finds study

Some cases of recurrent pregnancy loss may be caused by sperm DNA damage in the male partner, rather than by a problem in affected women, according to research to be presented Sunday, March 24 at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

Exposure to particulate air pollution may lead to reduced sperm production

Exposure to tiny air pollution particles may lead to reduced sperm production, suggests new research in mice to be presented Monday, March 25 at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

MSU professor receives NSF CAREER grant for biosensor diagnostics

One day, a technician in a small, rural hospital may be able to reliably diagnose breast cancer, Alzheimer's disease or traumatic brain injury using a tab of paper that would change color like a pH strip dipped in vinegar.

High-fat, high-sugar diet in mouse mothers causes problems in the hearts of offspring

A diet high in fats and sugars is known for its unhealthy effects on the heart. Scientists now have found that a high-fat, high-sugar diet in mouse mothers before and during pregnancy causes problems in the hearts of their offspring, and that such problems are passed down at least three generations, even if the younger generations only eat a standard mouse chow diet.
