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).

Brain scans link signs of cellular aging to symptoms of Alzheimer’s

According to a new study led by Anya Topiwala of Oxford Population Health, a division of the University of Oxford in the United Kingdom, and published on March 22nd, 2023 in the open-access journal PLOS ONE, changes in the brain caused by Alzheimer’s disease are connected to telomeres shortening, the protective caps on the ends of chromosomes that shorten as cells age.

How specialized plant “train tracks” can be used to feed the expanding population

A new study will examine the possibility that specialized plant “train tracks” that transport chemicals within cells could help in feeding the world’s expanding population.

RHOJ acts as a key regulator of EMT-associated resistance to chemotherapy

In spite of the ongoing development of new targeted therapies, chemotherapies remain the most popular used treatment for patients with advanced cancers. Chemotherapy resistance is one of the leading causes of cancer treatment failure and death.

Immunity adaptation found in genomes of Stone Age farmers

New research suggests that diversity in genes implicated in immunity might have facilitated the shift from hunter-gatherer lifestyles to agriculture that occurred in prehistoric Europe over the course of around 1,500 years.

Blunted inflammatory response in obese individuals responsible for susceptibility to severe COVID-19

Individuals who are obese may be more susceptible to severe COVID-19 because of a poorer inflammatory immune response, say Cambridge scientists.

Variations in methylation linked to age in the human sperm epigenome

A higher risk of reproductive and child health issues is linked to advanced paternal age. Increasing evidence points to age-related alterations in the sperm epigenome as one underlying cause.

Revealing how hematopoietic stem cells acquire malignant traits in cancer

Scientists from Lund University’s Faculty of Medicine have discovered a novel mechanism connecting ribonucleic acid (RNA) metabolism to the development of leukemia in patients with myelodysplastic syndrome (MDS).

DeLisi's new book underscores how most crime is never known to law enforcement

In his new book, Matt DeLisi, a world-renowned criminologist at Iowa State University, lays out evidence that Ted Bundy's criminal career was far lengthier and deadlier than the official record from 1974 to 1978.

Key Hox genes control stem cells involved in bone formation and repair

A new study discovered that genes that have long been known to regulate bone formation before birth also govern bone healing later in life.

Scientists devise a tiny, nano-sized sensor capable of detecting protein biomarkers

While a popular hobby for many, fishing is also a pastime full of uncertainty. Each time you have something on the line, you can never be completely sure what type of fish you've hooked until you pull it out of the water.

New study pinpoints key source of T cell "exhaustion"

Custom-made to attack cancer cells, CAR T-cell therapies have opened a new era in the treatment of human cancers, particularly, in hematologic malignancies.

Blunted inflammatory response could make obese patients more susceptible to severe COVID-19

Individuals who are obese may be more susceptible to severe COVID-19 because of a poorer inflammatory immune response, say Cambridge scientists.

DNA drugs help restore the normal processing of protein-encoding RNA

A protein named TDP-43 has been lost from its normal location in the nucleus of the cell in virtually all persons having amyotrophic lateral sclerosis (ALS) and in up to half of all cases of frontotemporal dementia and Alzheimer’s disease (AD).

Perspectives on nucleolar DNA damage response in the fight against cancer

Cancer, which affects so many people each year, relies on proteins to proliferate throughout the body. Scientists are damaging the disease’s protein factories as part of a new tactic to combat the widespread disease.

Cancer cells use new DNA repair mechanism to recover from next-generation cancer radiation therapy

A team of scientists led by Dr. Kei-ichi TAKATA from the Center for Genomic Integrity within the Institute for Basic Science (IBS), has discovered a new type of DNA repair mechanism that cancer cells use to recover from next-generation cancer radiation therapy.

Delaying paralysis in ALS by using designer DNA drug

In virtually all persons with amyotrophic lateral sclerosis (ALS) and in up to half of all cases of Alzheimer's disease (AD) and frontotemporal dementia, a protein called TDP-43 is lost from its normal location in the nucleus of the cell.
