The term "opioid epidemic" is outdated to the point where the message conveyed is inaccurate. Also, every time the phrase is used most people will automatically think "pills." But pills are now a minor contributor to overdose deaths; it is illegal street drugs – especially illicit fentanyl – that’s (by far) driving the surge in overdoses. Substituting the term "fentanyl epidemic" would instead shift the blame to where it belongs, while going a long way toward halting the demonization of vitally important medicines. Words matter.

While all uses of tobacco are bad for your health, we have maintained that vaping is both a lesser evil and a pathway to cessation. A new study looks at the effects of vaping and smoking on mitochondria, the engines of our lives.

Will there be pull incentives to support the broken antibiotics market? Where is Biden?

Are "ultra-processed" foods addictive? Some scientists say yes, pointing to experiments with sugar-craving rats and the difficulty many people have losing weight and keeping it off. Taken in isolation, these observations lend themselves to a food addiction model, but there's actually little evidence to support the theory.

A new rumor claims that Paxlovid, Pfizer's Covid drug, is merely a "dressed up" ivermectin molecule with little difference other than price. The term "Pfizermectin" is even being used to emphasize this. But biochemical and pharmacokinetic data say otherwise. Here are the numbers.

The built environment can heat and cool us, human error, debunking the latke, and who is really anti-nuclear power?

The last month has divided conventional wisdom. If cases continue to decline, the pandemic might be on its way out. If they trend upward, another winter surge might be on its way. Here we look for clues from data [1] through November 15, focusing on vaccination.

Can avoiding certain foods reduce your dementia risk? One nutritional psychiatrist seems to think so, but the evidence is much messier than it looks at first glance.

Those were the words of Christian Dior, who may have recognized a connection between the volatiles around us and our behavior. As a parent and now grandfather, I must agree with my wife; there is something special about sniffing an infant's head. Is it something they release or that we have applied, like baby shampoo? A new study suggests an evolutionary role for the smell of an infant.

One recent article in the bioethical literature bemoaned the expense of pursuing this noble career. Worse still, is that no one really knows what qualifies one to practice bioethics. But at $80,000 for advanced certification, it’s still a lot cheaper than a law or medical degree (although perhaps not quite as expensive as a degree in theology – which some claim might be more helpful).
