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).

Comprehensive profiling of human-to-human oral and intestinal microbial transmission

Researchers identified widespread bacterial strain sharing among humans (>10 million sharing instances) with distinctive patterns of transmission including vertical transmission, transmission within households, and the population.

Are dysregulated metabolism and inflammation contributing factors to the ongoing symptoms in long-term COVID-19 syndrome patients?

Researchers reported that dysregulation in energy metabolism and inflammation could contribute to long-term COVID-19 syndrome.

Prevalence of antibiotic-resistant bacteria not higher among babies delivered by cesarean section

Imagine a horse race, where the winner takes it all and is awarded both food and protection against enemies. In the same way, bacteria compete with one another in the gut of newborn babies.

Genotyping technology may help increase the number of kidney transplantations and reduce wait times

ABO blood-type compatibility between organ donors and recipients is crucial for safe transplantations. Across the different ABO blood groups, longer wait-times for a kidney transplant are often experienced by patients who have type B blood because it is a less common ABO blood type, resulting in fewer donors.

Research explores the utility of epigenetically predicted BMI

DNA methylation is an accurate predictor of current BMI and a poor predictor of future BMI.

Epigenetic alternations associated with common genital malformation in male babies

An alarming increase in the occurrence of the most common genital malformation in male babies, hypospadias, is likely due to environmental factors, such as toxicant exposure, which alter epigenetic programming in a forming penis.

Exploring a novel amplicon-based mpox virus sequencing strategy

Researchers described the development of a sequencing strategy based on amplicons for mpox detection.

Study: Exposure to high doses of micro-sized polyethylene has adverse effects on cells

Exposure to high doses of micro-sized polyethylene has adverse effects on cells, a new study from the University of Eastern Finland finds.

Study shows the modulatory effect of resistance training on the endoplasmic reticulum in older adults

Aging involves a balance between oxidants and antioxidants, low-grade inflammation and a protein response that occurs at the cellular level, which is responsible for many health disorders.

Using the power of light to transform analytical workflows in the life sciences

In this interview, we speak to Svea Cheeseman at Refeyn about their SamuxMP products used for the analysis of adeno-associated viruses (AAV) capsids.

First-ever method for analyzing RNA sequencing data genome-wide using a 'pantranscriptome'

Analyzing a person's gene expression requires mapping their RNA landscape to a standard reference to gain insight into the degree to which genes are "turned on" and perform functions in the body.

New test 'fishes' for multiple respiratory viruses using DNA as 'bait'

A new test that 'fishes' for multiple respiratory viruses at once using single strands of DNA as 'bait', and gives highly accurate results in under an hour, has been developed by Cambridge researchers.
