Researchers have discovered antibiotic resistance genes in the bacteria of a South American tribe never exposed to antibiotic drugs. This suggests some bacteria have always been antibiotic resistant.
Mice lacking a gene implicated in human anorexia and bulimia weigh less than other mice. Such animals also display a variety of behavioral disorders. This points to a genetic basis for eating disorders.
A genetic analysis of ancient and modern maize has revealed the crop’s complex domestication history. It began as a Mexican wild grass and developed into the plant capable of being used to produce corn porridge and tortillas.
Meghan Andrews has linked together two of her interests: photography and raising awareness about Huntington disease in a new photo book that captures the journeys of Canadian families affected by Huntington disease.
A low number of children around the world suffer with a rare disease called Hutchinson-Gilford Progeria syndrome. This condition leads to premature ageing and it is caused by a defective protein. A substance from broccoli may provide a treatment.
Next Generation DNA Sequencing has been made available for clinical. This new technology offers a 1000-fold precision increase over previous methods. It is known as Preimplantation Genetic Screening.
DNA sequencing of 360 tomato varieties has produced a genetic history of the fruit. The study has revealed that DNA around genes can lead to larger fruit size or enhanced resistance against diseases.
Who owns your genes? You? Big Pharma? Or should it be for the public good? At present the balance is with the company that patents the genetic material. Is this right? Not according to an Ottawa hospital.
A study into zebrafish has helped identify the cause of an unknown genetic disorder affecting a boy and two of his uncles. Although no cure is imminent, the study could pave the way to alternative approaches for dealing with rare genetic diseases.
The Federal Court of Australia has rejected an appeal of a ruling that allows companies to patent isolated human genes. This reignites the debate: who owns your genes - you or the company that extracts them?
Research from the Salk Institute for Biological Sciences has pin-pointed the gene responsible for sleep and wake cycles, and could explain the reason why many folk find it difficult to adjust their sleep cycles when flying between time zones.

By studying rats, researchers have unearthed an epigenetic link between a mother's diet and an offspring's risk of future obesity. This link relates to the blocked expression of a gene which goes onto trigger overeating.
