Nutritional epidemiology is notorious for producing sensational, conflicting results that confuse us all. We’re stuck with observational studies that can be twisted in countless ways to get different outcomes. Enter a new tool aiming to cut through this mess by testing all possible analytical choices and showing how flexible and unreliable these studies can be.

Will Cole, an alternative healthcare provider with a massive social media following, sells wellness and scary-sounding pseudo-diseases. His empire, like other functional medicine hucksters, sells supplements and aligns with celebrities for promotion and legitimacy. Let’s tease apart the hype from the hyperbole.

The concept of a “leaky” brain is an enigma, the fortress of our brain, seemingly protected by the blood-brain barrier now disrupted. However, to understand whether a breach has altered our cognitive function we need to better understand our protector.

Glaucoma stands as a preventable purveyor of blindness, particularly among Black and Hispanic communities. Genetic predispositions, socioeconomic disparities, and systemic barriers make glaucoma's impact disproportionately skewed. Here's a look why.

An excellent new tool that uses a technology called microindentation can measure the health of bone tissue directly and safely.

For woodworkers, the table saw stands as both a revered tool and a potential danger. One saw, SawStop, uses an innovative technology to prevent the saw from cutting more than wood. The feds are now considering mandating this technology, provoking a web of industry interests and regulatory hurdles.

Among the most creative and original mathematical thinkers (explanations of her work are virtually incomprehensible to us mortals who communicate in words rather than symbols), Amalie “Emmy” Noether’s name is associated with countless theorems, mathematical constructs, and key advances in abstract algebra, many of which are essential to modern physics.

As long as we don't run out of chemicals, we will never run out of chemical scares. Most are unfounded, especially the current one – that the use of methylene chloride to decaffeinate coffee will somehow harm you. The numbers say otherwise. There is nothing to worry about here.

It's easy to lose sight of the visceral fear and uncertainty that pervaded the early days of the pandemic.
With each iteration, AI becomes both student and teacher, trapped in an echo chamber of its own creation.
From Wendy's ill-fated foray into dynamic pricing to the prices of Ticketmaster and Live Nation, the line between innovation and exploitation grows increasingly blurred.

Under the guise of improving care, it can be argued that electronic medical records end up diminishing it. Here's how.

Twenty-three Salmonella infections reported across nine states have prompted a recall of eggs by the dozens (well millions, actually.) Worried about the eggs in your fridge? Read on to learn if you should check your carton a bit more closely before making this morning's omelet.

From a security standpoint, the only thing that matters is that our soldiers are effective at killing people and breaking things. Does acupuncture help accomplish that? We presented one opinion last week. Now, here's a second viewpoint on the matter.

It's one thing for Gary Bettman to be on the wrong side of a health issue as important as concussion-caused brain damage. It's quite another for the National Hockey League Commissioner to go on America's largest sports-talk radio station and be incorrect about the underlying science. But the medical experts swiftly straightened him out.

The chemistry of mucus is conceptually identical to that of hair. Which means the same reaction can style your hair or help you breathe better. Ain't chemistry great?

There's simply no benefit to supplemental Calcium or Vitamin D for the patient who is well. So why do we continue to waste our money on these supplements? The US Preventative Services Task Force again weighs in to recommend against their use. 

It's hard to find anything but sadness in the continued epidemic of deaths from drug overdoses. But many of these individuals become organ donors. And despite concerns about infection, organs retrieved and transplanted from these deaths do very well in their new hosts. 

The link between the bacteria in our bodies, or microbiome, and diseases of the immune system has been established for some time. However, the role bacteria play is not well understood. A new paper takes that linkage to the next level, showing how one bacterium may play a big role in autoimmune diseases, such as lupus.  

After a series of recent trips to the hospital, the 92-year-old wife of the former president has decided not to seek any additional medical treatment.

A study published in The Lancet concludes that one additional drink per day increases a person's risk of stroke, coronary disease, heart failure, fatal hypertensive disease, and fatal aortic aneurysm. Alcohol may not be to blame, but we can't determine this because the authors didn't even bother to collect data on it.

Being a night owl could literally kill you; that's according to the latest study from nearly half a million participants in the U.K. Experts say night owls are living in a world structured for early risers, or larks, and are at a higher risk for obesity, hypertension, cardiovascular disease, and early death. 

Fifteen years after Moneyball, Michael Lewis' seminal book that upended Major League Baseball's old-school ways of evaluating players, we're now on the verge of having that once-reviled, back-office stat geek ... in person, in the dugout – in uniform! – dispensing data-driven advice directly to the manager ... during the game. 

A case of the "stomach flu" is bad enough, so the last thing we need is our own immune system making it worse. But that's just what can happen, courtesy of an obscure component in the intestinal lining called tuft cells. These little devils help us fight off parasites. But they also give norovirus a place to replicate and a reservoir in which to reside.

Baby aspirin is prescribed for many people who, as it turns out, will experience no benefit. It results from the difficulty in reconciling population studies with the patient in front of you. Doctors end up broadening the groups. Call it "Indication Creep."  

With the law and the public's attitude relaxing toward marijuana, people are opening up about their smoking habits. Surveying those 18 and older in Colorado, the CDC learned that the occupational group it categorized as "art-design-entertainment-sports-media" is the state's top cannabis consumer. Which profession smoked the least? Here's the answer ... 

Next month, the International Agency for Research on Cancer is expected to announce its choice for new director, the person who will lead the organization for the next five years. ACSH President Hank Campbell sizes up the front-runners and gives you his pick to lead the agency.
