Monday's health links

Good morning, all!

1. Purdue researchers develop a "breast on a chip."  They hope it will help them test the use of nanoparticles to detect and target cancer cells within the breast's ducts. Past efforts to access the ducts through the nipple have had difficulty getting past the first third of the breast. The idea here is that nanoparticles with a magnetic core can float through the fluid in the ducts, pulled by a magnet, all the way to the back of the ducts where it is believed most breast cancer start.
2. The loss of an American fitness legend - Jack LaLanne dies at 96. Thanks, Jack!
3. Lowering the exercise standards for Canadians.  I get it - the new standards are minimums and the idea is to encourage people to do SOMETHING. But if you need any more evidence in favour of lots of vigorous, regular exercise than the long life of Jack LaLanne I don't know what it is.
4. Positive emotions linked to improved health and quality of life as one ages. Really?! This is news!?
5. And finally, a list of ten super foods that includes some I haven't seen highlighted before: walnut oil, quinoa, black beans, sweet potatoes, cabbage, oats, flax seeds, avocado, kale and strawberries. In praise of this, I'm highlighting recipes for each of these powerful little buggers over on my recipe blog today. Quick - go there now!
