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).

800-year-old mummies from Mongolia help advance DNA extraction

Dr. Heather Coyle and three forensic science graduate students at the University of New Haven have developed a new method for preparing certain skeletal remains for DNA extraction thanks to some 800-year-old mummies from Mongolia and the research the group is doing for the Smithsonian Institution.

Transgenics sped up

A new method of constructing artificial plant chromosomes from small rings of naturally occurring plant DNA can be used to transport multiple genes at once into embryonic plants where they are expressed, duplicated as plant cells divide, and passed on to the next generation -- a long-term goal for those interested in improving agricultural productivity.

Massive reanalysis of genome data solves case of the lethal genes

It is better to be looked over than overlooked, Mae West supposedly said. These are words of wisdom for genome data-miners of today.

Genetic ancestry testing could spawn unwelcome societal consequences

For many Americans, the potential to track one's DNA to a specific country, region or tribe with a take-home kit is highly alluring.

New stem cells by reprogramming

Researchers are discovering new ways to help ‘de-program' specialised cells so that they can be re-programmed to form a range of different types of tissue, an international meeting of stem cell biologists was told.

Childhood epilepsy research offers new hope for seizure control

Scientists still do not know what causes epileptic seizures, but researchers from Melbourne's Howard Florey Institute are one step closer to solving this puzzle with the help of their newly developed genetically modified epileptic mouse.

X chromosomes and evolution

Researchers at the University of Rochester believe they have just confirmed a controversial theory of evolution.

Tolerance to inhalants may be caused by changes in gene expression

Changes in the expression of genes may be the reason why people who abuse inhalants, such as spray paint or glue, quickly develop a tolerance, biologists at The University of Texas at Austin have discovered.

HPV test beats Pap in detecting cervical cancer

A new study led by McGill University researchers shows that the human papillomavirus (HPV) screening test is far more accurate than the traditional Pap test in detecting cervical cancer.

Health Discovery receives notice of allowance of U.S. patent application covering kernel selection methods

Health Discovery Corporation has announced that the U.S. Patent and Trademark Office has issued a notice of allowance of HDC's patent application covering methods for selection of kernels, i.e., functions or algorithms that are used to transform input data into a different configuration, known as "feature space", which allows for easier recognition of patterns within the data.

Defects in Jhdm2a gene could be the cause for some cases of male infertility

Scientists at the University of North Carolina at Chapel Hill have identified a gene crucial to the final step of the formation of a functional sperm cell.

Phase II map of human genetic variation

The International HapMap Consortium today published analyses of its second-generation map of human genetic variation, which contains three times more markers than the initial version unveiled in 2005.

Genetics play a key role in obesity

New evidence that genetics plays a key role in obesity is published today in the International Journal of Bioinformatics Research and Applications.

New technique to probe the dynamics of the Holliday junction

The Holliday junction is a four-stranded DNA structure that forms during a process known as homologous recombination, which occurs when damaged DNA is repaired. Understanding how DNA repairs itself is an essential step in ultimately developing therapies for genetic disorders.

Discovery of new area for exploration of schizophrenia

Schizophrenia may occur, in part, because of a problem in an intermittent on/off switch for a gene involved in making a key chemical messenger in the brain, scientists have found in a study of human brain tissue.
