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).

Innovative method greatly simplifies the complexity of delivering vaccines

Future vaccine delivery may rely on everyday items like BBQ lighters and microneedles, thanks to the ingenuity of a team of Georgia Institute of Technology and Emory University researchers.

Red blood cells play a much larger role in the immune system than previously thought

New research has revealed that red blood cells function as critical immune sensors by binding cell-free DNA, called nucleic acid, present in the body's circulation during sepsis and COVID-19, and that this DNA-binding capability triggers their removal from circulation, driving inflammation and anemia during severe illness and playing a much larger role in the immune system than previously thought.

Researchers identify new gene variants that may cause inherited retinal dystrophies

An international team of researchers, led by scientists at University of California San Diego and Shiley Eye Institute at UC San Diego Health, has broadened and deepened understanding of how inherited retinal dystrophies (IRDs) affect different populations of people and, in the process, have identified new gene variants that may cause the diseases.

Understanding how brain cells talk could help find new treatments for neurological, psychiatric conditions

Experts from the University of Nottingham have discovered that reversing the modification of molecular messages at synapses in the human brain, may contribute to reversible mental health conditions such as anxiety, and memory diseases such as dementia.

Deep learning algorithm can accurately detect molecular pathways, key mutations in colorectal cancer

A new deep learning algorithm created by researchers from the University of Warwick can pick up the molecular pathways and development of key mutations causing colorectal cancer more accurately than existing methods, meaning patients could benefit from targeted therapies with quicker turnaround times and at a lower cost.

Review shows UV radiation in HVAC systems inactivates viruses

The researchers followed international standards for systematic reviews, performed a comprehensive search, and gathered findings from 32 relevant studies published between 1936 and 2020. This study is published on the medRxiv* preprint server.

Researchers discover new way to jump-start the immune system to attack tumors

Immunotherapy is a promising strategy to treat cancer by stimulating the body's own immune system to destroy tumor cells, but it only works for a handful of cancers.

Researchers identify the genetic changes responsible for drug resistance in tuberculosis

Using cutting-edge genomic sequencing techniques, researchers at the University of Oxford have identified almost all the genomic variation that gives people resistance to 13 of the most common tuberculosis (TB) drug treatments.

Study highlights the critical role of junk DNA in mammalian development

Nearly half of our DNA has been written off as junk, the discards of evolution: sidelined or broken genes, viruses that got stuck in our genome and were dismembered or silenced, none of it relevant to the human organism or human evolution.

Researchers reveal the mechanism of artificial chromosome formation in C. elegans' embryos

A research team led by Dr Karen Wing Yee YUEN, Associate Professor from the School of Biological Sciences at the University of Hong Kong (HKU), revealed the mechanism of artificial chromosome (AC) formation in the embryos of the model organism Caenorhabditis elegans, a 1-mm long, transparent nematode.
