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).

Study of cancer radiation therapy shows that DNA building blocks are susceptible to fragmentation

A new study relevant for cancer radiation therapy shows that DNA building blocks are susceptible to fragmentation. Scientists now have a better understanding of how short DNA strands decompose in microseconds

Scientists examine part of sample consisting of non-human DNA

Much of what we know about Oetzi - for example what he looked like or that he suffered from lactose intolerance - stems from a tiny bone sample which allowed the decoding of his genetic make-up.

Study finds that friends who are not biologically related still resemble each other genetically

If you consider your friends family, you may be on to something. A study from the University of California, San Diego, and Yale University finds that friends who are not biologically related still resemble each other genetically.

New femtosecond infrared light source helps to directly visualize hydrogen-bonded molecules

Using a newly developed, ultrafast femtosecond infrared light source, chemists at the University of Chicago have been able to directly visualize the coordinated vibrations between hydrogen-bonded molecules -- the first time this sort of chemical interaction, which is found in nature everywhere at the molecular level, has been directly visualized.

Prostate cancer more likely to be aggressive in younger men

The number of younger men diagnosed with prostate cancer has increased nearly 6-fold in the last 20 years, and the disease is more likely to be aggressive in these younger men, according to a new analysis from researchers at the University of Michigan Comprehensive Cancer Center.

Mount Sinai awarded AHA grant to prevent heart disease among NYC children and parents

Mount Sinai Heart at Icahn School of Medicine at Mount Sinai has been awarded a $3.8 million grant by the American Heart Association to promote cardiovascular health among high-risk New York City children, and their parents, living in Harlem and the Bronx. With assistance from the NYC Administration for Children's Services, the research team's mission is to reduce each child's future risk of obesity, heart attack, stroke, and type 2 diabetes.

New study reveals how genetic defect may make people more susceptible to developing melanoma

A new study by University of Kentucky researchers shows how a genetic defect in a specific hormonal pathway may make people more susceptible to developing melanoma, the deadliest type of skin cancer.

CRISPR system involved in promoting antibiotic resistance

CRISPR, a system of genes that bacteria use to fend off viruses, is involved in promoting antibiotic resistance in Francisella novicida, a close relative of the bacterium that causes tularemia.

Researchers recover genome of bacterium from 700-year-old skeleton

European researchers have recovered a genome of the bacterium Brucella melitensis from a 700-year-old skeleton found in the ruins of a Medieval Italian village.

Researchers describe innovative technique for early disease detection

Despite impressive medical strides, cancer remains a leading killer and overwhelming burden to healthcare systems, causing well over a half million fatalities per year with a projected cost of $174 billion by 2020, according to the National Cancer Institute.

New research opens up potential new therapeutic targets for hard-to-treat food allergy

New research in Nature Genetics identifies a novel genetic and molecular pathway in the esophagus that causes eosinophillic esophagitis (EoE), opening up potential new therapeutic strategies for an enigmatic and hard-to-treat food allergy.

Sunscreens do not protect totally against development of skin cancer, shows study

The researcher at the Neurosciences Institute, Joint Center of the University Miguel Hernández (UMH) in Elche and the Higher Council for Scientific Research (CSIC), Berta López Sánchez-Laorden co-authored a study that concluded that sunscreens do not protect totally against the development of skin cancer.

New genetic programs for taking blank-slate stem cells and turning them into human blood

The ability to reliably and safely make in the laboratory all of the different types of cells in human blood is one key step closer to reality.

CYD-TDV vaccine shows moderate protection against dengue in Asian children

The first dengue vaccine candidate (CYD-TDV) to reach phase 3 clinical testing has shown moderate protection (56%) against the disease in Asian children, according to new research published in The Lancet.

2D IR spectroscopy reveals intermediate structure during amylin aggregation pathway

Amyloid diseases, such as Alzheimer's disease, type 2 diabetes, cataracts, and the spongiform encephalopathies, all share the common trait that proteins aggregate into long fibers which then form plaques.

Scientists develop new weapon against bacterial infections in the form of tiny DNA pyramids

Bacterial infections usually announce themselves with pain and fever but often can be defeated with antibiotics - and then there are those that are sneaky and hard to beat. Now, scientists have built a new weapon against such pathogens in the form of tiny DNA pyramids.

Scientists develop RNA that binds cGMP

The transmission of signals within cells is dependent on cyclic guanosine monophosphate (cGMP) as an important secondary messenger. German scientists have now developed an RNA that binds cGMP. As reported in the journal Angewandte Chemie, it is possible to suppress the cGMP signal cascade in genetically modified cells that produce this RNA.

Bacteria in healthy women bladders differ from bacteria in women with incontinence

Bacteria found in the bladders of healthy women differ from bacteria in women with a common form of incontinence, according to researchers from Loyola University Chicago Stritch School of Medicine.

NANOG gene linked to tumours derived from stratified epithelia

Scientists from the Spanish National Cancer Research Centre (CNIO) have discovered that NANOG, an essential gene for embryonic stem cells, also regulates cell division in stratified epithelia-those that form part of the epidermis of the skin or cover the oesophagus or the vagina-in adult organisms.

TCGA finds novel mutations in key cancer-causing pathway in lung adenocarcinoma

Researchers from The Cancer Genome Atlas Research Network have identified novel mutations in a well-known cancer-causing pathway in lung adenocarcinoma, the most common subtype of lung cancer.
