A group of scientists in lab coats push a large boulder labeled with pillars of scientific reasoning against a tide of social media icons, misinformation, and sensationalist digital content, moving toward a signpost for healthier living.

SBM And The Battle For Information

Part of the reason for forming SBM in the first place is because my colleagues and I perceived that we were engaged partly in a long struggle for control over information—specifically the quality of health information being pushed to the public, including the media and regulators. We did not anticipate how much this battle would change over the last few decades, and...

Keep An Eye On This Ebola Outbreak

Ebola is a deadly disease caused by the orthoebolavirus group of viruses. It is infamous for being extremely deadly, with a mortality rate as high as 80-90%. Luckily, it only spreads by direct contact with body fluids, not through the air. However, it is mainly a problem in sub-Saharan Africa, where the lack of infrastructure and some cultural practices can cause it...

Nobel Prize in Physiology or Medicine 2026

Each year I like to document the Nobel Prize in Physiology or Medicine here on SBM – it’s a great reminder of the power of science to transform medicine. There is nothing like it in so-called “alternative medicine”, which is still peddling basically the same snake oil and energy nonsense of previous centuries, just with updated marketing. This year the prize goes...

The CDC Has Been Hollowed Out

A new report from the NYT tells a chilling story of how the Centers for Disease Control has been hollowed out over the last 18 months under Trump and RFK Jr. We have been covering this story as it has been developing, but it is useful to take a look at where we are and the totality of the destruction that has...

AI Moral Decision-Making

Body Integrity Dysphoria – A Rare and Informative Condition

A fifty-year-old man was admitted through the emergency room with extensive dry ice injuries to his left leg. For two days his doctors tried to save the leg, but the damage was too extensive, so eventually they had to perform a below-knee amputation. During this time the patient also suffered from small strokes due to fat emboli from the damaged leg. After...

Ivermectin and Hydroxychloroquine Six Years On

More than six years after the pandemic arrived and ivermectin and hydroxychloroquine were first touted as COVID cures, the evidence shows more than ever that they don't work.

The NFL and Brain Injury

Last week I wrote about traumatic brain injury (TBI). By coincidence, the BMJ just published a study looking at a type of TBI called chronic traumatic encephalopathy (CTE), which is caused by repeated head injuries over a long period of time, even those not severe enough to cause an acute TBI. They were looking specifically at former NFL football players, because that...
