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).

Blond gene among Solomon islanders baffles researchers

It is known that skin and hair color is mostly inherited from parents but whole populations have evolved to share certain traits. It is also known that people who live closer to the equator have darker skin and hair colour to protect against the Sun. The exception is found in the Solomon Islands, an archipelago east of Papua New Guinea which has the highest proportion of natural blonds outside of Europe despite being just south of the equator.

Researchers discover how protein ARTD1's DNA recruitment is regulated during inflammation

During inflammation, controlled gene expression is necessary in order to allow the organism to mount an effective defense response. For this process, the protein ARTD1 is removed from the DNA.

Cancer genomes in a common database and computation of disease drivers

The emerging field of "personalized" or "precision" medicine holds great promise in the fight against cancer. If scientists can identify the genetic changes that drive each patient's cancer cells, they can use that information to develop targeted treatments. But achieving this goal will require massive amounts of genomic and clinical data and a sophisticated infrastructure to manage and analyze the data.

Scientists are working out how sequencing the human genome can help treat disease

Though the human genome has been sequenced, scientists are still trying to figure out how the accomplishment can help people, for example, how it can be used to treat disease. As University of Massachusetts Amherst geneticist Jacob Mayfield notes, "It was easy to think of the human genome as the big prize, but what we realize now is, it's just a foot in the door."

Human iPS cells accrue genetic changes at about the same rate as replicating cells

A team of researchers from Johns Hopkins University and the National Human Genome Research Institute has evaluated the whole genomic sequence of stem cells derived from human bone marrow cells—so-called induced pluripotent stem (iPS) cells—and found that relatively few genetic changes occur during stem cell conversion by an improved method.

Mirror-microRNAs control multiple aspects of brain function

Our genes control many aspects of who we are - from the colour of our hair to our vulnerability to certain diseases - but how are the genes, and consequently the proteins they make themselves controlled? Researchers have discovered a new group of molecules which control some of the fundamental processes behind memory function and may hold the key to developing new therapies for treating neurodegenerative diseases.

Detrimental effect of tetracycline on male reproductive function, sperm viability of pseudoscorpions

In a paper published today in Nature's open access journal Scientific Reports, researchers at the University of Nevada, Reno report that male pseudoscorpions treated with the antibiotic tetracycline suffer significantly reduced sperm viability and pass this toxic effect on to their untreated sons. They suggest that a similar effect could occur in humans and other species.
