Social media is awash in testimonials from anonymous men who claim that testosterone-replacement therapy (TRT) helped them beat depression, sexual dysfunction, obesity and other maladies that often impact men as they age. Such compelling endorsements no doubt appeal to others who struggle with these critical health issues, but do they stand up to scientific scrutiny? Let's take a closer look.

We wait, eyes open, knowing Chat-AI is on the loose and a new wave of cataclysm is coming: more abused kids, more empty chairs at dinner tables, more emergency holds in psych wards. If regulators aren’t stepping in and courts are hamstrung, the Bots may be on the verge of takeover – the last hope may be lawyers who can outwit them. How sad.

A sweeping new analysis of more than 4,000 brain scans reveals that our brains’ neural networks don’t simply mature and then decline; they reorganize through a series of distinct life-stage “epochs,” each with its own opportunities and vulnerabilities. These structural shifts help explain why our abilities, behaviors, and risks for specific neurological conditions change so markedly across the lifespan.

Can you benefit from light therapy? It depends. Treatments range from nonsensical to possibly useful to those proven to be effective.

The past twenty years have seen gluten sensitivity transformed from a fringe concern into a mainstream cultural identity, powered more by consumer experience, psychology, and industry dynamics than by definitive biological mechanisms. This rapid rise has left many people unsure where scientific consensus ends and popular belief begins.

House on fire? No worry. Sabre-toothed tiger chasing you? Big deal. Major surgery scheduled? Yawn. Fortunately for mankind (or at least most of us), there’s a sedative called Versed — and it relaxes you so thoroughly that… who cares?

America’s overdose crisis isn’t the simple story we’ve been told for years. A new investigation reveals how two key graphs — one famous, one ignored — shift entirely the way we understand what happened, why deaths keep rising, and why current policies continue to fail. This op-ed explains why the familiar “four-phase opioid epidemic” narrative collapses under scrutiny.

A new randomized trial from North Carolina suggests that digital tools like mPATH may slightly boost participation in CT lung cancer screening—yet the overall uptake remains strikingly low. Despite proven survival benefits and minimal risks, only a small fraction of eligible smokers proceed with screening, revealing deep systemic and informational barriers. Understanding why participation is so limited is essential to improving outcomes for one of the deadliest yet most survivable cancers when detected early.

We often talk about science as if it were a purely logical enterprise. Yet, the way we ask questions—and even the kind of questions we think matter—is shaped by something far older than the scientific method: the architecture of our brains. Whether we lean toward “how” or “why” reflects not only cognitive habits but cultural values, emotional instincts, and the stories we tell about knowledge itself. Understanding this split may help explain why scientific communication so often falters in the space between data and meaning.

Taking Ozempic or Wegovy? Yale researchers just dropped a bombshell: two glasses of wine now hit like four, your BAC climbs higher and stays there longer, and you might not even feel it coming. And here’s the wild part: doctors say this same effect could accidentally be the most powerful tool we’ve ever had against alcohol addiction.

Celebrities have discovered the ultimate performance enhancer: supplements that boost their bank accounts more than your health. With a dash of glamour and a sprinkle of pseudoscience, they promise you can buy your way to Beckham-level vitality—one overpriced scoop at a time. Spoiler: the glow is mostly marketing.

Scientific guidance isn’t carved in stone—it shifts as new evidence reshapes old assumptions. The recent reversal of long-standing hormone therapy warnings highlights how politics, public trust, and evolving data collide and why “follow the science” is far more complicated—and more vital—than the slogan suggests.

Doctors were once considered Gods, or at least godlike. Lawyers and now philosophers have long tried to grab a similar status -- by birthing artificial people. In the beginning, lawyers created corporate “persons.” And now they’re about to midwife their latest miracle: the AI-person. If you think a ChatBot with rights, duties, and the capacity to be sued (or sue you) sounds absurd, just wait until it asks for counsel.

Experiencing heartburn? Then consuming an acidic product like apple cider vinegar isn't the solution. The logic is simple: if you've got excess stomach acid, more acid won't help. But up is down in the world of alternative medicine, so let's take a closer look at the bad chemistry behind this "natural" treatment for acid reflux.

As daylight fades, many feel the “winter blues,” a dip in energy and mood. And for roughly 5% of adults, it’s Seasonal Affective Disorder (SAD), a real depression tied to shorter days, not just cold weather.

It's about time. The U.S. Mint made its last penny on Thursday. Too bad that 328 billion of them were minted before that. They are a nuisance and not worth the energy (and pollution) necessary to mine, mint, and distribute them. Here are my two cents.

It’s neither hot, sunny, nor anywhere near National Egg Cream Day. Could there be a better reason to write about it?

Sometimes big breakthroughs in science come from very small changes, curiosity, and more than a little luck. A new study from researchers at Oregon Health & Science University shows how swapping a single atom in a known compound created an experimental cancer-fighting molecule with a completely different mode of action and improved properties.

Once, pasteurization helped conquer “The White Plague”, saving millions of lives from TB and other diseases. Now, legislators across the nation are inviting it back—served in a glass of “natural,” unpasteurized milk. The raw milk revival isn’t just a quirky food fad; it’s a symptom of the growing war on science waged by those who are supposed to protect us.

Generally recognized as safe (GRAS) has been the law of the land in the United States regarding food and beverage ingredients for decades. With MAHA’s stated quest to ensure that our food is made with only the safest ingredients, it seems obvious that GRAS would be on their radar. However, the selective outrage over some policy loopholes but not others tells a different story, particularly when examining the similar regulatory gaps in the dietary supplement industry.

For years, reactions to histamine-rich foods like red wine, aged cheeses, and dark chocolate were dismissed as vague "sensitivities" or even psychosomatic quirks in mainstream medicine. Histamine intolerance has been so overhyped as a trendy diagnosis by flaky alternative-medicine practitioners that those who genuinely suffer have struggled to be heard. Though still limited, emerging evidence suggests the condition does exist, backed by clinical observations and biochemical mechanisms.

Ever wonder what VO2 Max really means? It’s your body’s ultimate engine metric—the maximum amount of oxygen your muscles can use during all-out effort. Does aging tank your VO2 Max? Yes; unless you fight back.

November 19th is National Bidet Day. Why? Who knows. But let's not waste an opportunity to make fun of it. Dust off that disco suit.

Nature gives us one incredible surprise after another. If you're a bird lover and have been admiring bluebirds, jays, or barn swallows, you're not seeing a blue bird; it s actually brown. Here's how they trick you.

Scientists created a form of “super ice” that conducts electricity rather than simply freezing by compressing water under enormous pressure and bombarding it with powerful X-rays. This discovery reveals how water might behave deep inside planets like Uranus and Neptune, offering insight into their magnetic fields and internal heat.
