First Pig Lung to Human Transplant

In the midst of all the controversy surrounding the science of healthcare, certain technologies continue to progress in the background, with the promise of transforming the practice of medicine. One of them is the development of genetically modified animals as a source for organ transplants. I most recently wrote about this earlier this year, specifically about an experiment to transplant a pig...

Health Narratives on Social Media

Engaging on social media about health issues can be daunting. I know this is not news, but it is important to understand what is happening phenomenologically. I also think it’s a microcosm of what’s happening to our society in general because of social media – we no longer have a shared fact-based reality as people increasingly live in different universes of information....

Lithium and Alzheimer’s Disease

This is an interesting story, which has been all over the news so worthy of covering here. Alzheimer’s disease (AD), the major cause of dementia in humans, is a very complex disease. We have been studying it for decades, revealing numerous clues as to what kicks it off, what causes it to progress, and how to potentially treat it. This has lead...

HHS To Cut Funding for Vaccine Research

I get it. I am as tired of writing about RFK Jr.’s dismantling of the evidence-based federal medical infrastructure as you are of reading about it. I have tried to focus on anything else, as you can see from my recent articles here. There is still a lot of bad medical science and misinformation out there that needs dealing with. But I...

Review Recommends High Dose Statins

The exact role of different types of dietary fat and the best approach to prevention in cardiovascular disease has been somewhat controversial. However, the level of controversy among experts is much less than that being generated in the public by outliers and contrarians. Since cardiovascular disease remains a major source of morbidity and mortality, it’s important for the public to be kept...

The Healthcare Costs of Fossil Fuels

While the debate continues about the true impact of burning fossil fuels on the climate and what the optimal policy response should be, we need to make sure we do not neglect another aspect of fossil fuel use – air pollution and the effect it has on our health. There is a growing body of research showing a significant negative impact with...

A sad woman sits with her hand on her forehead, looking at a laptop. On the screen, a friendly robot asks, "How are you feeling?" in a speech bubble.

AI Therapists – Not Ready for Prime Time

Artificial Intelligence (AI) applications are being rolled out at a furious pace. There is no doubt they are potentially powerful tools, although with flaws and limitations. But one thing that large language models do well is mimic conversational speech. They are great chatbots. For this reason one of the early uses of these chatbots is as AI therapists. There are no hard...

A comic shows text: "When you see a claim that a drug or vitamin 'kills cancer cells in a petri dish,' keep in mind: So does a handgun." An illustrated figure points a gun at a lab dish on a desk.

Oregano Snake Oil

Oregano oil is being marketed with a variety of health claims, including as a treatment for various infections, inflammatory disorders, and skin conditions. This TikTok video by an “Ayervedic specialist” is typical of the claims made for this product. The claims suffer all the usual problems of the supplement industry, which we can go through them in some detail. But here is...

Real Time Computer Communication

For those with advanced ALS (amyotrophic lateral sclerosis) or certain brainstem strokes, they can be what is referred to as “locked in”. They are mostly paralyzed. A tip of the basilar artery brainstem stroke, for example, can leave one only able to move their eyes. Many with ALS, long before they get to this point, lose the ability to speak because of...
