DNA News and Research

RSS

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).

New guidelines for prevention and early detection of cervical cancer

The American Cancer Society (ACS), the American Society for Colposcopy and Cervical Pathology (ASCCP), and the American Society for Clinical Pathology (ASCP) have proposed new guidelines for the prevention and early detection of cervical cancer.

Scientists determine structure of GAG proteoglycan

If genes provide the blueprint for life and proteins are the machines that do much of the work for cells, then carbohydrates that are linked to proteins are among the tools that enable cells to communicate with the outside world and each other. But until now, scientists have been unable to determine the structure of a biologically important so-called GAG proteoglycan-or even to agree whether these remarkably complex molecules have well-defined structures.

Women more likely to develop lupus at earlier ages

Debilitating. Destructive. Life-altering. These are just a few words used to describe autoimmune disease. Autoimmune diseases affect women 8 times more often than men, with lupus being one of the most disruptive. Lupus is a disease that occurs when a person's immune system attacks its own tissues and organs instead of attacking foreign invaders such as common viruses and bacteria. Lupus often results in wide-spread inflammation, pain, swelling and organ/tissue damage throughout the body.

New sequencing method can identify genetic variants linked to ASD

Geneticists at Emory University School of Medicine have demonstrated a method that enables the routine amplification of all the genes on the X chromosome. The technology allows the rapid and highly accurate sequencing and identification of novel genetic variants affecting X chromosome genes.

Colon cancer may be linked to a bacterium that causes appendicitis and gum disease: Study

A new study shows that a bacterium that causes appendicitis and gum disease is also found in colon tumors. Researchers suggest that it may set the stage for colorectal cancer, the second-deadliest malignancy. The bacterium – fusobacterium might play a role in determining the prognosis of colorectal cancers and shaping their treatment, according to two research teams independently reporting a relationship between the rod-shaped microbe and cancers of the lower digestive system.

Scientists discover a way to accurately map typhoid outbreaks in the city

In the mid-nineteenth century, John Snow mapped cases of cholera in Soho, London, and traced the source of the outbreak to a contaminated water pump. Now, in a twenty-first century equivalent, scientists funded by the Wellcome Trust working in Kathmandu, Nepal, have combined the latest in gene sequencing technology and global positioning system (GPS) case localisation to map the spread of typhoid and trace its source.

Broken biogeochemical cycle of phosphorus will impact food security

Should the periodic table bear a warning label in the 21st century or be revised with a lesson about elemental supply and demand? If so, that lesson could start with one element considered a staple of life - but growing endangered, like the Asiatic dhole - phosphorus.

New book investigates what fuels the passion for science

On April 8, 1982, alone in a laboratory, chemist Dan Shechtman looked through an electron microscope and saw an impossible pattern. He had discovered quasicrystals. But his groundbreaking findings were rejected, even mocked, by the scientific establishment for years.
