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).

Hidden pancreatic stem cells revealed

Wanted: stems cells. Just like those absconders chased by police all over the world, everybody can tell about their good deeds but none really knows how to recognize them.

Rak gene helps protect tumor suppressor in breast cancer

Scientists at The University of Texas M. D. Anderson Cancer Center have discovered a gene that protects PTEN, a major tumor-suppressor that is reduced but rarely mutated in about half of all breast cancers.

BRAF gene mutation is a crucial skin cancer switch

Up to 70 per cent of melanoma skin cancers could be triggered by a particular genetic mutation, according to a Cancer Research UK funded study published in Cancer Cell.

Researcher tackles deadly brain tumors

Natalie Ciaccio, a fourth-year graduate student researcher in the Department of Pharmaceutical Chemistry at the University of Kansas, is investigating what might be an ideal target for anti-cancer drug therapy, and she is focusing her work on brain tumors specifically.

Molecule called miR-29b could be a potent treatment for acute myeloid leukemia

A new study by Ohio State University cancer researchers shows that boosting the level of a molecule called miR-29b in acute myeloid leukemia (AML) cells can reverse gene changes that trap the cells in an immature, fast growing state of development.

Scientists detect molecular obesity link to insulin resistance, type II diabetes

A molecular switch found in the fat tissue of obese mice is a critical factor in the development of insulin resistance, report scientists at the Salk Institute for Biological Studies.

Schizophrenia could be caused by faulty signalling in the brain

In the biggest study of its kind, scientists looking in detail at brain samples donated by people with the condition have identified 49 genes that work differently in the brains of schizophrenia patients compared to controls.

Researchers discover structure-building role for 2 non-coding RNAs

Most of the DNA in the nucleus of each of our cells is converted into RNA, but only a small fraction of these RNA molecules serve as coding templates for the synthesis of proteins.

Discovery of marker for severity in adult brain cancer

Researchers at UT Southwestern Medical Center have identified a new biological indicator that may help identify which brain-cancer patients have the most aggressive forms of the disease.

Discovery of gene linked to short-rib polydactyly syndrome

After 12 years of searching, UCLA scientists have tracked down the first known gene mutation responsible for a heartbreaking disorder that kills newborn babies.

Health benefits, consequences of folic acid dependent on circumstances

For the past several decades, evidence has shown that greater dietary intake of the B-vitamin, folate, offers protection against the development of certain common cancers and reduces neural tube defects in newborns, opening new avenues for public health interventions that have a great impact on health.

New carbohydrate synthesis technology

Carbohydrates are part of our daily vocabulary. We all know they're part of a healthy diet. We know they're in breads and pastas. We know they have something to do with starches and sugars. But, even though carbohydrates are so familiar, there's still a lot for science to learn about them.

Self-collection of samples in sex workers works best when screening for STIs

Researchers at the University of Westminster have used a simple and convenient method for screening female commercial sex workers (CSW) for sexually transmitted infections (STIs) without the need for them to attend clinics.

World's first nanofluidic device with complex 3-D surfaces

Researchers at the Commerce Department's National Institute of Standards and Technology (NIST) and Cornell University have capitalized on a process for manufacturing integrated circuits at the nanometer (billionth of a meter) level and used it to develop a method for engineering the first-ever nanoscale fluidic (nanofluidic) device with complex three-dimensional surfaces.
