As we age, bones creak, hearing wanes, and cognition diminishes. Promises of rejuvenation have always besieged a vulnerable market seeking the fountain of youth. Now, there seems to be a clinically tested elixir that promises to restore lost brain power – a simple Chinese herbal remedy. So, does it work?

Our behavior seems to be built by evolution, and it's sometimes paradoxical. To borrow from the hard sciences, our behavior exhibits complementarity. We are largely felicitous to our family and friends, yet stand-offish (if not aggressive) to “others” we may encounter. Willful ignorance straddles that complementarity borderline. A new study offers insight into what's really going on.

Long COVID has long been a syndrome in search of a disease and, more importantly, an underlying explanation. A new study in Cell tries to use Occam’s Razor to find the underlying cause. While not truly causal, it is an interesting hypothesis – with lots to unpack.

Alzheimer’s disease is a stealthy killer, quietly and slowly stealing a half million new American minds yearly. The disease should present a major public health emergency, but serious governmental efforts to address the problem began only recently. Sadly, the problem also presents a marvelous marketing opportunity. Leave it to pharma and its affiliates to try and exploit a frightened, nervous, and vulnerable public.

Either of two phenomena may be at work -- the "placebo effect" or the "post hoc, ergo propter hoc" (after this, therefore because of this) fallacy.

The FDA seems intent on imposing a ban on menthol cigarettes and cigars, despite evidence from Europe that it only fuels a black market. And despite evidence in the U.S. that it may worsen inequities in law enforcement.

Why did so many people opt not to get COVID boosters? That is a significant public health question. A newly reported survey provides some answers.

Much of the blood drawn for laboratory analysis is wasted. In a clinical setting where your blood is being taken multiple times a day, wouldn't it be better for the laboratory to use a smaller amount – and let you keep the difference?

A new study demonstrates an association between elevated blood levels of erythritol and an increasing risk of MACE – major adverse cardiovascular events – such as heart attack, stroke, heart failure, death, and the need for coronary revascularization. What the study and the researchers found was “lost in translation.” Let’s see for ourselves.

Flu shots perform inconsistently because it's hard to anticipate which strains of the virus will be circulating in a given year. So far in 2023, it appears that the latest round of vaccines are working well. The FDA has determined that Sudafed PE doesn't work. Questions and accusations are flying as a result: why were we sold a useless decongestant in the first place? And more importantly, who's to blame for this public health blunder?

Advil, aka, ibuprofen, is one of the most widely used drugs in the world. It's effective for relief of pain, inflammation, and fever. It can also wreak holy hell on your stomach. Unfortunately, the two effects go together. Grab the Rolaids. It's time for an Advil lesson.

It's irrelevant whether you like turkey or not because someone is going to be handing you a plate of it very soon. And after the meal, there's a good chance that you'll get sleepy. But will the cause of your drowsiness be the turkey, the booze, or your brother-in-law's tedious commentary about his golf game?

Some people drink coffee, and the next thing you know, they're trying to climb the Empire State Building. But others feel little or nothing. What's going on?

Child abuse manifests in various forms. One is the “Shaken Baby,” where rapid head shaking allegedly causes neurological injury and death. Until recently, a constellation of bodily injuries was considered adequate evidence to convict an indicted abuser. No longer. Recent cases have held that “Shaken Baby Syndrome” is not a valid diagnosis. One court just held the diagnosis should be a legal determination – not a medical one, rejecting all medical testimony and exonerating alleged abusers.

I have previously authored many articles about per- and polyfluroalkyl substances (PFAS), also known as “forever chemicals,” and the misinformation and lack of scientific credibility surrounding them. However, Europe has outdone the U.S. on the absurdity of their proposed regulations on these chemicals. On February 7, 2023, the European Chemicals Agency (ECHA) proposed to ban all PFAS, which would affect more than 12,000 chemicals. To do this, they used a definition of PFAS so broad that it includes almost any chemical that contains fluorine [1]. What is going on?

“Last month, California lawmakers passed a bill that would decriminalize the personal possession of small amounts of a few plant-based psychedelics. This raised hopes that this could be the first of many reforms to unlock the therapeutic potential of psychedelics. Unfortunately, Governor Newsom vetoed the bill, citing reasons that can only be characterized as specious.”

Politicians are attacking a safe and important class of pesticides – neonicotinoids – with unwarranted bans and restrictions. These policies will be devastating to farmers, costly to consumers, and damaging to the environment.

Why are some people fully protected by vaccination, or infection-acquired immunity to COVID, when others are not? Does the fault lie with the vaccines? Do some individuals mount a more robust immune response? A new study provides an answer that lies in between those choices and gives me a chance to write about the power and limitations of metaphors.

Regulators are supposed to abide by the “bargain” that society has made with them: Civil servants are granted lifetime tenure and are protected from political pressure and retaliation, in return for which they are supposed to make decisions based solely on the public interest. But, often, they do not. 

It's 1980 and Queen released a huge, timeless hit, "Another One Bites the Dust." Imagine if someone wrote a parody about today's "fake" opioid crisis and put it to music. Wouldn't that be entertaining? Imagine no longer. Here it is.

Another article in the ongoing war over the protective value of masks. The latest report, with senior author Vinay Prasad, effectively builds and demolishes a straw man of the authors’ creation, then does some out-of-season cherry-picking. In the end, the “study” sheds more shade than light.

Long COVID comprises a set of persistent symptoms developing weeks after COVID per se has waned. Long COVID cases have been remarkably stable; about 36% of those who had experienced COVID developed long-term symptoms. As such, long COVID deserves more attention.

Today, there is simply too much known in far too many diverse fields for any person to hold it all in their brain. This means that, no matter how smart one might be, there are times when we have to push the “I believe” button and simply accept the statements of others. The problem is that these others are too often wrong, the topic is too often very important, and the statements made are too wildly disparate. We feel we must choose, yet we don’t know how.
