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).

Researchers use supercomputer to unveil new methods for DNA mosaic recognition

As humans, we each have trillions of cells. And each cell has a nucleus with individual genetic information –DNA – that can mutate to create an abnormality.

New genetic condition that raises vulnerability to opportunistic infections

An international consortium co-led by Vanderbilt University Medical Center immunogeneticist Rubén Martínez-Barricarte, PhD, has discovered a new genetic disorder that causes immunodeficiency and profound susceptibility to opportunistic infections including life-threatening fungal pneumonia.

New computational tool for long-read RNA sequencing

An evolving RNA molecule can be cut and joined, or spliced, in various ways on the path from gene to protein before being translated into a protein. Using a technique called alternative splicing, multiple proteins can be encoded by a single gene.

Environmental DNA analysis of microbial communities can help trace a region's water cycle

Environmental DNA analysis of microbial communities can help us understand how a particular region's water cycle works.

New center to assist in understanding non-coding cancer genome

The MacMillan Center for the Study of the Non-Coding Cancer Genome (MCSNCG) was officially launched by the New York Genome Center (NYGC) on January 18th, 2023.

Utilizing "cyborg cells" in environment protection and medicine

At the University of California, Davis, biomedical engineers have developed “cyborg cells” that are partially alive.

Potential to rectify various disease-causing mutations enhanced by CRISPR-based enzymes

Designing genome editing strategies for each patient’s mutation would be impractical and expensive because many genetic diseases are induced by diverse mutations spread across an entire gene.

New method to treat MRSA infections with penicillin-type drugs

Researchers from the University of Galway have reported a new discovery that could enhance treatment options for superbug MRSA infections using penicillin-type antibiotics that have proven ineffective on their own.

New toolkit enables researchers to map an individual’s RNA data to a much richer reference

Examining the gene expression of a person needs mapping the RNA landscape to a standard reference. This is done to gain an understanding of the degree to which genes are “turned on” and execute the functions in the body.

New scalable approach for the diagnosis of multiple respiratory viruses

Cambridge scientists have created a novel test that “fishes” for many respiratory viruses at once using single strands of DNA as “bait” and provides extremely accurate results in under an hour.

Electrochemical biosensor for detecting antibodies

Although it frequently necessitates a challenging laboratory procedure, the quantitative detection of specific antibodies in complex samples like blood can provide information on a variety of diseases.

Insights into the role of the germline in de novo mutation

The male reproductive system is a hotspot for the introduction of new genes. Perhaps that might assist in understanding why fathers tend to pass on more new mutations than mothers do. However, it does not explain why older fathers pass on more mutations than younger fathers.

Ten years and 1,000 studies later, epigeneticists discover problems in their arsenal

Twenty years ago, following the initial sequencing of the human genome, geneticists started carrying out extensive genome-wide association studies to find genomic regions connected to human disease.

Quicker and affordable method of extracting DNA from elephant dung

With the aid of a novel DNA-collection technique, researchers can now collect genetic data from elephants without endangering the animals or endangering themselves.

Importance of involving descendant communities in ancient DNA research

Researchers can track human evolution and make crucial findings about modern populations by analyzing ancient DNA.

Key genes driving cleft lip and palate identified

A research group headed by the University of Iowa recognized three genes that, when deleted, produce cleft lip or palate, a facial abnormality that affects around one in every 1,600 babies in the United States, according to the US Centers for Disease Control and Prevention.

Breeding climate-proof crops aided by exotic wheat DNA

Research from the Earlham Institute in Norwich, in partnership with the International Maize and Wheat Improvement Centre (CIMMYT), provides much-needed hope for enhancing crop resilience and food security in the face of climate change following a year in which temperature records have been broken.

New solution to treat diseases caused by exaggerated inflammation

A recent study guided by the Instituto Gulbenkian de Ciência (IGC) shows how anticancer drugs reduce inflammation, establishing them as prospective sepsis treatments.

Effective anticancer strategy for selective killing of cancer cells

A study team headed by Dr Yuanliang Zhai from The University of Hong Kong’s (HKU) School of Biological Sciences and his associates from The Hong Kong University of Science and Technology (HKUST) and Institut Curie in France discovered a new mechanism of the human MCM2-7 complex in controlling replication initiation, which can be employed as a unique and effective anticancer method with the potential for selective death of cancer cells.
