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).

Two genetic variants associated with increased susceptibility to severe dengue

Researchers in South East Asia have identified two genetic variants associated with increased susceptibility to severe dengue. The study, funded by the Wellcome Trust and the Agency for Science, Technology, and Research, Singapore, offers clues to how the body responds to dengue infection.

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.

RAZCER (Rapid Astrazeneca and CARO Evaluation of Radio-modifiers) awards announced - five Canadians win

Five leading Canadian radiation oncologists receive RAZCER Awards of $22,727 each for novel studies of radiation-drug interactions that have the potential to either protect normal tissues or sensitize tumours, and thus to enhance the effectiveness of radiation therapy for cancer patients. A selection committee of members of the Canadian Association of Radiation Oncology (CARO) selected the 2011 recipients from among a field of 12 applicants. Astrazeneca provides the funds for the RAZCER Award as an educational grant.

Genetic mystery of bacterium causing ‘Black Death’ revealed

Between 1347 and 1351 - a period of just five years, Europe's Black Death wiped out about 30 million people - 30 to 50% of the population on the continent. Now geneticists have reconstructed the genome of the bacterium that caused the plague. It is found to be an ancient strain of a bacterium called Yersinia pestis very similar to the strain the exists today.
