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).

Whole genome sequencing may guide blood cancer treatment

For certain blood cancers, such as acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), deciding whether patients need an aggressive treatment typically hinges on a set of lab tests to identify genetic changes.

Information from ancient teeth could reveal new insights about the past

There's a surprising amount of information stored in the hardened plaque, or calculus, between teeth. And if that calculus belongs to the remains of a person who lived in ancient times, the information could reveal new insights about the past.

RNA editing events influence gene expression and phenotypic manifestation

Combining computational mining of big data with experimental testing in the lab, researchers at Children's Hospital of Philadelphia (CHOP) have identified RNA editing events that influence gene expression and, in turn, the phenotypic manifestation of that expression.

Phase 2 clinical trial is now open at Columbia to test gene therapy for dry macular degeneration

A phase 2 clinical trial is underway at Columbia University and NewYork-Presbyterian to test an investigational gene therapy for dry age-related macular degeneration, a progressive, chronic eye disease with no cure and a leading cause of blindness in the United States.

Somatic gene mutations in brain cells could contribute to schizophrenia pathology

Schizophrenia is a neurodevelopmental disorder that disrupts brain activity producing hallucinations, delusions, and other cognitive disturbances. Researchers have long searched for genetic influences in the disease, but genetic mutations have been identified in only a small fraction--fewer than a quarter--of sequenced patients.

Study describes the infection of human cells by intestinal pathogen during spaceflight

Astronauts face many challenges to their health, due to the exceptional conditions of spaceflight. Among these are a variety of infectious microbes that can attack their suppressed immune systems.

Rapid increase of UK SARS-CoV-2 variant found in sewage in England between October 2020 to January 2021

A new study confirms the utility of wastewater surveillance as an important new tool in this regard by showing the presence of the UK SARS-CoV-2 variant in wastewater samples from London early in November, with increasing frequency thereafter.

New, easy-to-perform test can rapidly detect widely circulating SARS-CoV-2 variants

Rutgers researchers have designed a new rapid test that can detect all three of the rapidly spreading variants of the coronavirus in a little over one hour – much shorter than the three to five days required by current tests, which can also be more technically difficult and expensive to perform.
