A simple method developed for 3-D bio-fabrication based on bacterial cellulose

Bacterial cellulose (BC) nanofibers are promising building blocks for the development of sustainable materials with the potential to outperform conventional synthetic materials. BC, one of the purest forms of nanocellulose, is produced at the interface between the culture medium and air, where the aerobic bacteria have access to oxygen. Biocompatibility, biodegradability, high thermal stability and mechanical strength are some of the unique properties that facilitate BC adoption in food, cosmetics and biomedical applications including tissue regeneration, implants, wound dressing, burn treatment and artificial blood vessels.

Canada–US Free Trade Agreement (CUSFTA) increased caloric intake in Canada

A new study published in the American Journal of Preventive Medicine shows that the 1989 Canada-US Free Trade Agreement (CUSFTA) was associated with an increase in caloric availability of approximately 170 kilocalories per person per day in Canada. These findings suggest that the rise in caloric intake and obesity in Canada since the early 1990s can be partially attributed to its close trade and investment arrangements with the US.
