Worried that your beloved gel manicure just got labeled dangerous? Don’t be. The “banned” ingredient (TPO) is safe at the tiny amounts in gel polish — so safe that Europe’s own scientific panel found a 1,500-to-1 safety margin before regulators pulled the plug.

Unlike measles or polio vaccines, which last a lifetime, the flu virus mutates constantly, so we need a new shot every year. This year’s quadrivalent vaccine targets four strains and cuts your risk of getting sick by about 40–60%. Even if it’s not a perfect match, it's always worth getting.

Health and Human Services Secretary Robert F. Kennedy, Jr., cheered Tyson Foods Company’s decision to drop high fructose corn syrup (HFCS) from its branded products by the end of this year. However, nothing supports the secretary’s claim that swapping HFCS for table sugar (sucrose) makes you healthier. Science shows your body processes them the same way—and too much of either is harmful.

In an age where corporate jobs dissolve into jargon, screens eclipse books, and TikTok rewires attention spans, we may be quietly losing the very capacity to think deeply. As loyalty, logic, and literacy erode under the weight of screens and shallow work, intelligence itself may be in retreat. What happens to a society when reflection gives way to noise?

Anonymity and amplification have transformed hateful whispers into viral shouts. Social media platforms claim that their algorithms can filter out harmful speech, yet studies reveal that their judgments are uneven and often unjust. Responsibility, once enforced by presence, words spoken face-to-face, with neighbors and critics watching, may have to be reclaimed by conscience.

The stock-trading website Raging Bull just gave Cocrystal Pharma, a clinical-stage biotech, a big thumbs up for its experimental antiviral norovirus inhibitor. The stock went nuts in anticipation of the first-ever drug for the infection. Is Raging Bull really Raging BS? Or is there something here?

Ultra-processed foods have become a primary scapegoat for nearly every conceivable health problem. When researchers cannot explain the cause or increased risk of a disease, they often cite observational studies linking these products to adverse outcomes. This concern is partly justified: beyond their processing, many ultra-processed foods are calorie-dense, hyperpalatable, and often modified in texture, which can accelerate consumption by increasing the number of bites per minute.

Shield laws promise to protect clinicians who act in good faith, but today they stand at the edge of a constitutional conflict where medicine collides with politics and technology. By protecting providers when care crosses digital and geographic borders, these laws test the reach of state sovereignty and the resilience of federalism itself. They force us to consider how far protection should go before it begins to erode accountability to patients and to the society that grants medicine its trust.

AI may soon barge into the courtroom. It certainly is sitting in the entry portals. As artificial intelligence uses DNA-driven face prediction tools to corral suspects and construct lineups, law enforcement is enticed, but individual rights may be sacrificed. Vigilance is key.

Ever wondered why your routine check-up is less than satisfying? Hidden thinking errors quietly skew medical judgment, leading clinicians to label perfectly ordinary people as “difficult” and overlook the mind-body link that could unlock real relief. Challenging these mental shortcuts might transform the experience on both sides of the stethoscope.

Ever feel overwhelmed by endless food or information? Let’s dive into the science of enough— a simple, ancient secret backed by modern science: stop at 80% full.

Flu changes every year, so our vaccine has to change with it. Here’s the quick what-and-why behind the annual shot, how it’s picked, made, and when to get it.

Stem cells made a public splash with large research breakthroughs in the 90s and early 2000s. However, since then, stem cells have largely been adopted by the alternative medicine and wellness world as a cure-all. As always, if it sounds too good to be true, it’s definitely someone trying to make money off people’s vulnerabilities.

Our world is shaped by forces both vast and invisible. From the ocean’s deep influence on climate to the way social media manipulates our perception of time, science reveals patterns that reshape how we see daily life. Add in questions of national power—law vs. engineering—and humanity’s struggle with food waste, and you uncover the hidden systems driving our future.

“The stricter the law enforcement, the more dangerous the drug.” That’s how ACSH advisor and Cato Institute senior fellow Dr. Jeffrey Singer describes the iron law of prohibition, which he argues is driving America’s overdose epidemic. How do we reverse this alarming trend? Legalize all drugs. Dr. Singer joins us on a special episode of Science Dispatch to make that case.

Small Modular Reactors (SMRs) are often hailed as the future of nuclear power—compact, scalable, and potentially capable of delivering clean energy anywhere it’s needed. From powering remote mining towns and military bases to restoring electricity after natural disasters, SMRs promise a flexible solution to modern energy challenges. But how practical are these reactors outside of theory, and what obstacles stand between vision and reality?

Pain is not simply “in your head”—and reducing it to a brain-first narrative risks both stigma and substandard care. Real pain often originates in the body, whether from a fractured bone, spinal stenosis, or inflammatory disease, and deserves treatment grounded in science, not slogans. Patients need accurate, individualized solutions—not oversimplified mantras.

The line between difference, disability, and disease is constantly shifting, shaped as much by social attitudes as biology. A trait that seems like a simple variation in one context can become a disabling barrier in another, or be recast as a disease when medicine steps in. These boundaries don’t just describe people; they decide who gets care, protection, or stigma, and who is left out.

Against a backdrop of growing mistrust in experts—and a wellness industry that thrives on conspiracies and lone-wolf thinking—diet has become a prime target for misinformation. While gold-standard nutrition research is notoriously difficult to conduct, we still have enough evidence to separate fact from half-truths and fiction.

Cities don’t just sprawl—they metabolize. A new study shows that population, infrastructure, and emissions grow in lock-step, overturning the popular idea that bigger automatically means greener. The research rewrites the playbook for sustainable city planning and provides a great example of how science works.

Could drinking caffeine potentially weaken antibiotics in your system? A recent study says maybe.
Sounds alarming, right? But don't ditch your latte just yet—let’s dig into the facts.

You can’t turn on the TV without seeing ads for glucose-lowering GLP-1 drugs like Ozempic and Wegovy. A1C numbers are cocktail-party chatter. Helpful? Sure. But almost nobody knows the chemistry behind them. Here’s why the test works.

Abundance, not scarcity, has become the defining challenge of our time. From calorie-dense meals to the endless flood of digital content, we are surrounded by opportunities to consume far beyond what our bodies and minds require. Ancient wisdom and modern science both suggest the same solution: learning to stop at “enough” may be the surest path to health, clarity, and balance.

You asked, we answered. Join Cam English and Dr. Chuck Dinerstein on the latest episode of Science Dispatch as we tackle your questions about health and medicine. This week, we examine the risks and benefits of protein supplements, caffeine pouches and cold plunges.

The use of a newer class of opioids, nitazenes, is growing across the US. Once rarely seen in illicit markets before 2019, the drugs have been found on nearly every continent at this point. Their elevated potency—250 to 900 times stronger than morphine for the most common nitazene—makes them far deadlier than heroin and fentanyl. Can we slow or stop the use of these opioids before they do more damage?
