No difference found in drugs for macular degeneration
A team of planet hunters has announced the discovery of an Earth-sized planet orbiting a nearby star at a distance that places it squarely in the middle of the star's "habitable zone," where liquid water could exist on the planet's surface. If confirmed, this would be the most Earth-like exoplanet yet discovered and the first strong case for a potentially habitable one.

Pension reform vital to maintaining Canadians' standard of living
Johns Hopkins scientists have discovered that the over-activation of a single protein may shut down the brain-protecting effects of a molecule and facilitate the most common form of Parkinson's disease. The finding of this mechanism could lead to important new targets for drugs already known to inhibit it, thus controlling symptoms of the disorder, which affects about 1 million older Americans.
Proposed dietary guidelines for Americans sharply debated
As baby boomers retire in greater numbers, serious doubts continue to be raised about the ability of the retirement income system to provide adequate replacement wages for the next generation of Canadians.

Research suggests climate change target 'not safe'
Exacerbations in cystic fibrosis, or CF, may be linked to chronic infection with a bacterium called Stenotrophomonas maltophilia, which was previously thought to simply colonize the CF lung. The finding that chronic infection with S. maltophilia is independently linked with an increased risk of exacerbations gives clinicians and researchers a new potential measure of the health status of CF...
Researchers engineer adult stem cells that do not age
An analysis of geological records that preserve details of the last known period of global warming has revealed "startling" results which suggest current targets for limiting climate change are unsafe.

TRUST study data confirms safety and efficacy of erlotinib for advanced lung cancer
For the past three decades, saturated fat has been considered a major culprit of cardiovascular disease (CVD) and as a result dietary advice persists in recommending reduced consumption of this macronutrient. However, new evidence shows that saturated fat intake has only a very limited impact on CVD risk -- causing many to rethink the "saturated fat is bad" paradigm.
Featured in the October edition of the Journal of Thoracic Oncology, data from the Tarceva Lung Cancer Survival Treatment, or TRUST, confirms the safety and efficacy profile of erlotinib, a highly potent oral active, reversible inhibitor of epidermal growth factor receptor tyrosine-kinase activity in a large heterogeneous non-small cell lung cancer population.
