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 insight into the function of RNA helicases

If DNA can be compared to an architect who gets all the glory for designing the building, RNA can be compared to the engineer who often goes unrecognized, but is needed to turn the blueprints into a real three-dimensional, functional and safe structure.

IT has the power to transform the pharmaceutical industry

Information technology has the power to transform the pharmaceutical industry, if businesses apply it correctly. That’s the conclusion of Pharma 2010: Silicon Reality, a report from IBM Business Consulting Services (BCS).

Embryo testing could produce babies who might aid sick siblings

Parents with a child requiring stem cell transplantation can have genetic testing done on embryos prior to implantation to determine if the tissue type matches and the ensuing offspring could potentially serve as a donor to the affected child, according to a study in the May 5 issue of The Journal of the American Medical Association (JAMA).

Fabrication of microscopic polymeric structures on top of a human hair

Researchers in the laboratory of Boston College Chemistry Professor John T. Fourkas have demonstrated the fabrication of microscopic polymeric structures on top of a human hair.

Scientists find genetic link between prostate cancer and hereditary form of breast and ovarian cancer

A new study shows that the risk for prostate cancer is significantly elevated in men who are part of families with a hereditary form of breast and ovarian cancer. Researchers at Memorial Sloan-Kettering Cancer Center have determined that men in families carrying BRCA genetic mutations have a three- to five-fold increased risk of prostate cancer.

Researchers profile over 6000 genes in the two primary types of normal breast cells

For several years, scientists have attempted to identify gene expression changes, using microarrays or ‘DNA chips’, in order to understand and predict breast cancer onset, progression, and clinical outcome.

Developing smart drugs

Dana-Farber Cancer Institute Researchers, sensing an opening in the cancer battle, are mounting a quick thrust to flush out suspected molecular cancer triggers in tumor cells.

Scientists have discovered a genetic cause of cleft lip and palate in mice

By watching mice “dance” and comparing the DNA of the dancers to their flat-footed siblings, scientists have discovered a genetic cause of cleft lip and palate in mice, a finding that is already being used to search for a similar genetic defect in humans.

Time bomb in heart leads to heart failure in some congenital heart disease patients

However, surgical correction of certain forms of congenital heart disease may not fix the underlying molecular trigger that drives progressive heart failure and sudden death later in life, according to new research from the University of California, San Diego (UCSD) School of Medicine.

New technique of identifying genes may help researchers developing drugs

A quick new technique able to identify genes that evolve rapidly as well as those that change slowly already has pinpointed new targets for researchers developing drugs against tuberculosis and malaria, and it could do the same for other infectious diseases, according to a paper in this week's Nature.

Mystery surrounding ageing, death and cancer is dispelled by new study

Scientists from Cancer Research UK and Breast Cancer Campaign have uncovered the first evidence of an entirely new system for holding the ravages of time at bay.

Lou Gehrig’s disease gene discovered

A gene for a rare juvenile-onset form of amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease) has been isolated in families in the United States, Belgium and Austria, the Muscular Dystrophy Association (MDA) announced today.

The world's smallest computer made entirely of biological molecules

The world's smallest computer (around a trillion can fit in a drop of water) might one day go on record again as the tiniest medical kit.

Experimental smallpox DNA vaccine

In the first successful study of its kind, scientists have shown that a DNA-based vaccine for smallpox can protect nonhuman primates from monkeypox, a disease that resembles smallpox in humans.

UK scientists have discovered cancer cells life and death scenario following anti-cancer treatment

CANCER Research UK scientists have discovered how some cancer cells choose to live and others die following anti-cancer treatment, unveiling their findings in the prestigious journal PNAS today.

New analytical approach that combines genetic and clinical data to give individualized prognosis of cancer recurrence

Researchers at Duke University have developed a new analytical approach that combines genetic and clinical data to give cancer patients an individualized prognosis of their cancer recurrence. The information could prove critical in deciding how aggressively to treat the disease following surgery.
