Bacon, hot dogs, deli meats and other processed meats have long been considered guilty-pleasure foods that contain unhealthy preservatives, additives and any number of chemical ingredients. Now, food companies are trying to change that image by creating “natural” lines of processed meat products from real ingredients with no added preservatives.
A five-point plan to double our food supply faces serious obstacles, often because people don't want to give up what they have. When you take a satellite's-eye view, the world's food problem comes into clear focus: The planet's best agricultural land is not necessarily where the most people live.
(Chemistry professor Joe Schwarcz): Thanks to chemical ingenuity, we lead a colourful life. Synthetic dyes have served up a feast for the eyes but they may leave us starving for good health.
…Crows are unpopular, with good reason. They are obnoxious bird bullies with shrill voices, scattering trash and gumming up eavestroughs with their detritus. But perhaps our scorn springs from a deeper source.

Canadian researchers are trying to stamp out once and for all the skepticism faced by many who suffer severe, persistent pain. The revolution in research Canadians are helping to lead is aimed at showing just how real pain is.
(Chemistry professor Joe Schwarcz): "We can take for granted that Prince Rupert of the Rhine, Duke of Bavaria, first duke of Cumberland was not a hockey fan. He couldn't have been, given that he lived in the 17th century, about 200 years before the first organized hockey game was played…"
Parents taking a gander at their kid’s math textbook and wondering what the heck they’re looking at may want to check out a recent study from the Frontier Centre for Public Policy, based in Winnipeg. “Like many of my colleagues, I am dismayed by the state of the mathematics instruction in elementary and secondary schools,” states McGill math professor Pengfei Guan, quoted in Zwaangstra’s paper.
Thanks to a 4 year - $4 million grant from NSERC, the first Discovery Frontiers grant ever awarded, scientists from ten Canadian universities will now be able to collaborate with one another and with organizations from around the world to create a reference for the arctic land system. Geography professor Nigel Roulet will pursue his research into dissolved organic carbon in the Arctic waters.
