A need exists for rapid change in the social mindset of the next generation on antibiotics. If our youth do not appreciate the challenges facing public health officials today, they may end up living under the shadow of untreatable bacterial infections known as the post-antibiotic era.

If we can prevent infections before they begin, we can reduce the amount of antibiotics used in medicine. In light of the wide array of uses already known - and possibly more to come - we may have a simple yet effective way to use our own natural chemistry to keep us safe.

As Mother's Day approaches, Canadians will be celebrating the people who brought us into this world and nurtured us as we developed. Most of the adulation will be due to social graces, such as care, kindness, and those life lessons that always come in handy. But there are other reasons -- specifically molecular -- making Mom a baby's best ally.
We are facing an antibiotic resistance crisis. Almost every health authority has sounded the alarm and the most recognized authority, the World Health Organization, is doing all it can to slow the arrival of the post-antibiotic era. Yet, even as these calls are made, the use of these drugs continues to be unacceptably high.

"I was certain that I was going to die," said 25-year-old Ifrah in Somaliland, of her battle with tuberculosis. It's not something we should be hearing in 2017. An illness old enough to have been known as 'consumption' or 'The White Plague' should have its place in medical history -- not claiming 1.8 million lives a year.

At its core, antibiotic resistance is merely a coping mechanism. Bacteria are faced with a rather dire form of stress and need to find a way to cope. They can take the biological route of genetic mutation to render the drug useless. They also can gain a plasmid from the environment or another bacterium, to gain resistance mechanisms.

The concept of tolerance isn't relevant only in the microbial world. All biological life has the ability to tolerate, including humans. A perfect example of this phenomenon occurs in those able to eat hot, spicy foods. You might think they are simply born with stronger tongues. But that isn't the case. Instead, in most cases, a biochemical modification has occurred in one of the proteins found on the tongue.

Meat isn't what it used to be. What's typically sold in supermarkets isn't what our ancestors ate. And it sure isn't as healthy. But there's no need to despair. If you pay a little extra, these days you can find organic, traditionally-farmed meat.

Imagine a not-too-distant future where the survival of mankind hangs in the balance because modern medicine's frontline defenders -- antibiotics -- are being outsmarted by deadly microscopic enemies. I'm talking about the emergence of so-called "superbugs." They're real, they exist, and if you eat non-organic chicken, then you're all the more at risk.

At first glance, obesity may appear to be an easy problem to resolve. After all, most people may believe the answer lies in eating fewer calories and exercising more. While these are definitely helpful, obesity is an incredibly complex issue, and involves a number of factors ranging from genetics to socioeconomic status. So can antibiotics help?
The mere mention of nanotechnology may raise eyebrows. Yet worries should not be based on size but molecular composition instead. If a particle is made from plastic or heavy metals, concern is definitely valid. However, polylactic acid nanoparticles are biodegradable, making them perfect for use both in the environment and also in the body.
