Salmonella stays deadly with a 'beta' version of cell behavior
Salmonella cells have hijacked the protein-building process to maintain their ability to cause illness, new research suggests.

Maternal IV fluids linked to newborns' weight loss

Toronto researchers first to discover new genetic clue in the development of rheumatoid arthritis
Scientists at Mount Sinai Hospital, in collaboration with researchers at the University of Toronto, University Health Network and McGill University have obtained significant new insights into the causes of rheumatoid arthritis (RA) and other autoimmune disorders including type 1 diabetes, lupus and Graves disease.

How fatty diets cause diabetes
In a study published Aug. 14 in Nature Medicine, Sanford-Burnham scientists show that dietary fats interfere with an enzyme called GnT-4a glycosyltransferase, which is required for proper retention of glucose transporters in pancreatic beta cell membranes.

Stanford discovery may eliminate potentially lethal side effect of stem cell therapy
Researchers at the Stanford University School of Medicine have developed a way to remove these pluripotent human embryonic stem cells from their progeny before the differentiated cells are used in humans.

Short latencies shown for cancer in young workers with exposures to electro-magnetic fields
A study conducted by Hebrew University researchers has found that that there can be very short latency periods between the time of exposure and development of cancer in workers in tasks with intense or prolonged exposure to electro-magnetic fields.

Arthritis sufferers at increased risk of heart disease

New clue to Parkinson's
Alpha-synuclein -- a protein that forms clumps in the brains of patients with Parkinson's -- has likely been mischaracterized.

Increased tropical forest growth could release carbon from the soil
A new study shows that as climate change enhances tree growth in tropical forests, the resulting increase in litterfall could stimulate soil microorganisms leading to a release of stored soil carbon.

Gladstone scientists offer new insight into the regulation of stem cells and cancer cells
Scientists at the Gladstone Institutes have gained new insight into the delicate relationship between two proteins that, when out of balance, can prevent the normal development of stem cells in the heart and may also be important in some types of cancer.
