Mobilizing white blood cells to the lung: New discovery could lead to an improved influenza vaccine
Findings just published in the scientific journal Immunity by researchers at the Trudeau Institute shed new light on how a previously-unknown messaging mechanism within the human immune system prompts specific influenza-fighting cells to the lung airways during an infection. (2008-07-11)

Genetic cause of innate resistance to HIV/AIDS
Some people may be naturally resistant to infection with HIV, the virus that causes AIDS. The results of a study conducted by Dr. Nicole Bernard of the Research Institute of the McGill University Health Centre (MUHC) bring us closer to a genetic explanation. Her study findings were published on July 16 in the journal AIDS. (2008-07-17)

Does too much sun cause melanoma?
We are continuously bombarded with messages about the dangers of too much sun and the increased risk of melanoma (the less common and deadliest form of skin cancer), but are these dangers real, or is staying out of the sun causing us more harm than good? (2008-07-23)

Wilkins Ice Shelf hanging by its last thread
The Wilkins Ice Shelf is experiencing further disintegration that is threatening the collapse of the ice bridge connecting the shelf to Charcot Island. Since the connection to the island in the image centre helps to stabilise the ice shelf, it is likely the break-up of the bridge will put the remainder of the ice shelf at risk. (2008-07-11)

A dash of lime -- a new twist that may cut CO2 levels back to pre-industrial levels
Scientists say they have found a workable way of reducing CO2 levels in the atmosphere by adding lime to seawater. And they think it has the potential to dramatically reverse CO2 accumulation in the atmosphere, reports Cath O'Driscoll in SCI's Chemistry & Industry magazine published today. (2008-07-21)

Calcium may be the key to understanding Alzheimer's disease
Researchers at the University of Pennsylvania School of Medicine have shown that mutations in two proteins associated with familial Alzheimer's disease disrupt the flow of calcium ions within neurons. The two proteins, called PS1 and PS2 (presenilin 1 and 2), interact with a calcium release channel in an intracellular cell compartment. (2008-07-21)

Researchers find key to saving the world's lakes
After completing one of the longest running experiments ever done on a lake, researchers from the University of Alberta, University of Minnesota and the Freshwater Institute, contend that nitrogen control, in which the European Union and many other jurisdictions around the world are investing millions of dollars, is not effective and in fact, may actually increase the problem of cultural eutrophication.
