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).

Fruit and vegetables eaten before pregnancy lowers risk of leukemia

A new study led by researchers at the University of California, Berkeley, suggests that women who eat more vegetables, fruit and foods containing protein before pregnancy may have a lower risk of having a child who develops leukemia, the most common childhood cancer in the United States.

Novel pharmacological target for cannabinoid-based therapies

Cannabinoids, the active ingredients in marijuana, restrict the sprouting of blood vessels to brain tumors by inhibiting the expression of genes needed for the production of vascular endothelial growth factor (VEGF).

Pineal gland which regulates the cycles of sleep and waking evolved to improve vision

The pineal gland - which regulates the cycles of sleep and waking - appears to have evolved as an indirect way to improve vision, by keeping toxic compounds away from the eye

New method for building carbohydrate molecules

Chemists at the California Institute of Technology have succeeded in devising a new method for building carbohydrate molecules in a simple and straightforward way that requires very few steps. The new synthesis strategy should be of benefit to scientists in the areas of chemistry and biology and in the pharmaceutical industry.

What is Telomere crisis?

Telomere crisis is an important early event in the development of breast cancer, and its occurrence can be identified with precision, according to recent findings by a team of scientists at the Department of Energy's Lawrence Berkeley National Laboratory and the University of California at San Francisco.

Not only has life evolved, but life has evolved to evolve

That's the conclusion drawn by two Rice University scientists who have designed a computer simulation to test the idea that evolvability — the likelihood of genetic mutation — is a trait that can itself be favored or disfavored through the process of natural selection.

Scientists have turned procrastinating primates into workaholics by temporarily suppressing a gene in a brain circuit involved in reward learning

Using a new molecular genetic technique, scientists have turned procrastinating primates into workaholics by temporarily suppressing a gene in a brain circuit involved in reward learning. Without the gene, the monkeys lost their sense of balance between reward and the work required to get it, say researchers at the National Institute of Mental Health .

Correlation between HCV viral load and severity of liver disease

The significance of hepatitis C virus (HCV) serum titers (HCV viral load) has been examined in several clinical situations. There is much evidence that patients with a lower viral load have better response rates to anti-viral therapy compared to those with higher levels.
