In Focus - Computer Vision Syndrome
June 16, 2009
You're sitting in front of your computer at work and it's 3pm. Approaching the end of an important project, you're feeling good knowing you are about to be done - on time, or with time to spare - and now that the workload pressure is starting to ease you start thinking about what you are going to do after work. You pause, maybe have a little stretch, a yawn, and you notice your eyes are burning or are a little sore and dry. Now you are having trouble focusing and the project you were about to finish starts to feel daunting and more difficult.
Not Losing Sight
June 10, 2009
What's the Problem?
Vision impairment is defined as having 20/40 or worse vision in the better eye even with eyeglasses. Even people with the slightest vision impairment can experience challenges in their daily activities such as being able to obtain a driver's license.
Approximately 78,000 Canadians are estimated to develop vision impairment within the next year in addition to the already staggering statistic of 600,000 Canadians already living with vision impairment. This is significantly higher than a common age-related side affect, Alzheimer's, at an estimated 300,000 cases amongst Canadians.

March 31, 2009
For years researchers have puzzled over whether adaptation plays a major role in human evolution or whether most changes are due to neutral, random selection of genes and traits.
Geneticists at Stanford now have laid this question to rest. Their results, published online in Public Library of Science Genetics, show adaptation - the process by which organisms change to better fit their environment - is indeed a large part of human genomic evolution.

Open-Source Innovation
November 13, 2007

Digital Photography: The New Talk

Nothing stamps obsolescence more than a change in language.
