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).

Raising brain protein alleviates symptoms of Alzheimer's disease in mouse model

Boosting levels of a specific protein in the brain alleviates hallmark features of Alzheimer's disease in a mouse model of the disorder, according to new research published online August 25, 2016 in Scientific Reports.

NIBIB researchers develop nanovaccine to enhance cancer immunotherapy

NIBIB researchers have created a nanovaccine that could make a current approach to cancer immunotherapy more effective while also reducing side effects.

People with psychosis engage in low levels of physical activity, study reveals

A large international study of more than 200,000 people in nearly 50 countries has revealed that people with psychosis engage in low levels of physical activity, and men with psychosis are over two times more likely to miss global activity targets compared to people without the illness.

Assigning barcode to stem cells makes it possible to monitor large blood cell populations

By assigning a barcode to stem cells, researchers at Lund University in Sweden have made it possible to monitor large blood cell populations as well as individual blood cells, and study the changes over time.

Study shows Latinos age more slowly at molecular level than other ethnic groups

A new paper co-authored by a UC Santa Barbara researcher reveals that Latinos age at a slower rate than other ethnic groups. The findings, published in the current issue of Genome Biology, may one day help scientists understand how to slow the aging process for everyone.

Preimplantation genetic screening using next generation sequencing: an interview with Dr Luis Alcaraz

PGS, Preimplantation Genetic Screening, is a genetic test that analyses biopsied cells from embryos produced by in vitro fertilization (IVF) techniques. PGS determines whether the embryos are chromosomally normal (euploid) or not (aneuploid), thus giving the chance to transfer chromosomally normal embryos that are more apt to successfully implant and develop into a pregnancy.

Scientists explore geochemical conditions that may have led to first relevant organophosphates

The phosphate ion is almost insoluble and is one of the most inactive of Earth's most abundant phosphate minerals. So how could phosphate have originally been incorporated into ribonucleotides, the building blocks of RNA, which are considered to be among the earliest constituents of life? American and Spanish scientists have now identified reasonable conditions to mobilize phosphate from insoluble apatite minerals for prebiotic organophosphate synthesis, including ribonucleotides.

Researchers design DNA-based circuit that does math in a test tube

Often described as the blueprint of life, DNA contains the instructions for making every living thing from a human to a house fly.

DNA methylation changes that alter excitability may be involved in neuropsychiatric diseases

Diseases such as epilepsy, neuropathic pain, anxiety, depression, drug addiction and Alzheimer's are all associated with changes in the excitability of brain neurons.

Researchers investigate link between diet, obesity-linked Type 2 diabetes, and spinal disc degeneration

Can a diet high in processed fat and sugar and Type 2 diabetes cause degeneration of intervertebral discs in the spine? If so, what is happening, and can it be prevented? As part of an ongoing collaboration between Rensselaer Polytechnic Institute and the Icahn School of Medicine at Mount Sinai - a partnership that draws upon the expertise of both schools to address significant health problems - researchers hope to answer those questions by investigating the link between diet, obesity-linked Type 2 diabetes, and intervertebral disc degeneration.

Novel innovation could help scientists study new treatments for mitochondrial diseases

A new study published in the Proceedings of the National Academy of Sciences from the University of Missouri has succeeded in creating embryos with "heteroplasmy," or the presence of both maternal and paternal mitochondrial DNA.

Cloned Zika virus could be used for development of attenuated vaccine

Stopping the explosive spread of Zika virus - which can lead to birth defects in babies born to infected mothers - depends on genetic insights gleaned through new tools and models.

NIH researchers discover rare, lethal inflammatory disease that affects young children

National Institutes of Health researchers have discovered a rare and sometimes lethal inflammatory disease - otulipenia - that primarily affects young children. They have also identified anti-inflammatory treatments that ease some of the patients' symptoms: fever, skin rashes, diarrhea, joint pain and overall failure to grow or thrive.
