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).

A triplex SARS-CoV-2 assay based on nanopore sequencing is accurate, rapid and scalable

A novel breakthrough by a research group from Oxford Nanopore Technologies is a rapid way of testing and screening large numbers of samples for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

A fast, economical method to detect SARS-CoV-2 virus in untreated wastewater

A group of researchers have demonstrated that, from seven methods commonly used to test for viruses in untreated wastewater, an adsorption-extraction technique can most efficiently detect SARS-CoV-2. This gives us another tool to detect the presence and spread of the COVID-19 pandemic.

Researchers develop machine learning tool to predict necrotizing enterocolitis in premature infants

Necrotizing enterocolitis (NEC) is a life-threatening intestinal disease of prematurity. Characterized by sudden and progressive intestinal inflammation and tissue death, it affects up to 11,000 premature infants in the United States annually, and 15-30% of affected babies die from NEC.

CRISPR-based COVID-19 surveillance

A recent US study available on the medRxiv preprint server supports the use of self-collected oropharyngeal swabs, together with CRISPR- and PCR-based diagnostic assays, as rapid, feasible and reliable approach for the surveillance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in university students and other asymptomatic individuals

Genetic variant in Japanese population increases risk of interstitial lung disease among RA patients

In many cases, a complex interplay between our genes and the environment governs whether or not we will develop a certain disease. Interestingly though, researchers are discovering that the genetic component of disease predisposition may depend on our ethnic background.

Characteristics of electron emission from irradiated biomolecules

When fast-moving ions cross paths with large biomolecules, the resulting collisions produce many low-energy electrons which can go on to ionise the molecules even further. To fully understand how biological structures are affected by this radiation, it is important for physicists to measure how electrons are scattered during collisions.

New approach improves SCA1 symptoms in animal models

Research has shown that a mutation in the ATAXIN-1 gene leads to accumulation of Ataxin-1 (ATXN1) protein in brain cells and is the root cause of a rare genetic neurodegenerative disease known as spinocerebellar ataxia type 1 (SCA1).

Study shows link between high blood lead levels and aberrant methylation of DNA

Scientists have unveiled a correlation between high blood lead levels in children and methylation of genes involved in haem synthesis and carcinogenesis, indicating a previously unknown mechanism for lead poisoning.

A titanium oxide nanowire-based air filter can trap and destroy pathogens

Filter “paper” made from titanium oxide nanowires is capable of trapping pathogens and destroying them with light. This discovery by an EPFL laboratory could be put to use in personal protective equipment, as well as in ventilation and air conditioning systems.

NSD2 enzyme protects against cellular senescence

Researchers from Kumamoto University in Japan have used comprehensive genetic analysis to find that the enzyme NSD2, which is known to regulate the actions of many genes, also works to block cell aging.

Immunothrombotic dysregulation is key marker of disease severity in COVID-19

In severe cases of COVID-19, the infection can lead to obstruction of the blood vessels in the lung, heart and kidneys. Ludwig-Maximilians-Universitaet (LMU) in Munich researchers have now shown that activated immune cells and blood platelets play a major role in these pathologies.
