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 investigate prevention and therapy against monkeypox infection

Researchers reviewed the preventive and therapeutic measures against monkeypox.

Research suggests a new pathway for developing Parkinson's disease

There is currently no cure for Parkinson's disease (PD), and one of the main difficulties for developing treatments is that we don't know exactly how or why the disease occurs.

Study highlights the non-inferiority of frozen sperm for intrauterine insemination treatments

Patients having intrauterine insemination for fertility treatment can be reassured that the use of cryopreserved sperm instead of fresh is not associated with inferior outcomes.

Transcriptomic data reveals the evolutionary relationships of two groups of ancient invertebrates

Kamptozoa and Bryozoa are two phyla of small aquatic invertebrates. They are related to snails and clams (collectively called mollusks), bristleworms, earthworms, and leeches (collectively called annelids), and ribbon worms (nemertea).

New, safer CRISPR approach may help correct genetic defects in the future

Curing debilitating genetic diseases is one of the great challenges of modern medicine. During the past decade, development of CRISPR technologies and advancements in genetics research brought new hope for patients and their families, although the safety of these new methods is still of significant concern.

Chemical-based sequencing method to efficiently study DNA methylation

One way cells can control the activities of their genes is by adding small chemical modifications to the DNA that determine which genes are turned on or off.

Findings do not prove that monkeypox infection can occur from contact with surfaces

During the currently evolving outbreak of monkeypox cases outside of known endemic areas, transmission is mainly driven by close physical contact with symptomatic people.

New project aims to create a genetic blood test for prostate cancer in Black men

Researchers at the University of East Anglia, Imperial College NHS Healthcare Trust and Oxford Biodynamics are developing a new genetic blood test for prostate cancer in Black men - who are twice as likely to develop and die of the disease than white men.

Scientists use single cell techniques to uncover a central dichotomy for colorectal cancer cells

A team of clinician-scientists and scientists, led by the National Cancer Centre Singapore and A*STAR's Genome Institute of Singapore together with collaborators in Europe and South Korea, used single-cell techniques to uncover a central dichotomy for colorectal cancer cells, leading to a proposed update of the classification system for the disease.

HIV accelerates epigenetic aging soon after initial HIV infection

HIV has an "early and substantial" impact on aging in infected people, accelerating biological changes in the body associated with normal aging within just two to three years of infection, according to a study by UCLA researchers and colleagues.

Stopping a pervasive bacterium that makes millions sick each year

As we head outdoors this summer, scientists are working to clip the long, flexible appendages that enable the common bacterium Campylobacter jejuni to make its way from undercooked poultry and natural waterways into our intestinal tract where it makes millions of us sick each year.

Rice lab’s microbial community profiling software effectively identifies bacterial species

Part of a gene is better than none when identifying a species of microbe. But for Rice University computer scientists, part was not nearly enough in their pursuit of a program to identify all the species in a microbiome.

Study uncovers new gene that increases Alzheimer's disease risk in women

Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia, affecting more than 5.8 million individuals in the U.S. Scientists have discovered some genetic variants that increase the risk for developing Alzheimer's; the most well-known of these for people over the age of 65 is the APOE ε4 allele.
