The National Transplant Organization warns about the risk of consuming fecal capsules to improve the microbiota: "Neither safe nor effective"

El Periódico Mediterráneo - General4 September 2026 at 11:31

Spain's National Transplant Organization (ONT) and the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), through its Microbiota Study Group (GEMBIOTA), issued a warning this Friday about the potential risks of acquiring or using preparations or capsules made from human fecal matter outside authorized channels. These substances are being sold among private individuals to restore the intestinal microbiota.

The specialists warn that consuming these fecal capsules is neither safe nor effective. The practice consists of using processed human fecal matter in the form of tablets or preparations, supposedly with the aim of improving intestinal health through the restoration of the microbiota.

The ONT and SEIMC highlight that these treatments should not be obtained through unauthorized channels, as they represent significant health risks for users. The warning comes in the context of a growing popularity of procedures related to fecal microbiota transplants outside the controlled clinical environment.

Einstein's "happiest thought" passed the first test in the quantum world

An international team of researchers announced the first successful observation of the effect of gravity on a quantum object in free fall, in a study published in Science Advances. This experimental result demonstrates for the first time, more than a century after Einstein's prediction in 1907, the link between gravity and the quantum world — the physicist's so-called "happiest thought." However, the researchers emphasize that this experiment does not unify quantum mechanics with gravity, nor does it prove that gravity is a quantum phenomenon, but it provides experimental support for the idea that both domains are connected.

How technology is helping archaeology reveal larger and more sophisticated peoples in the Amazon

Recent studies using LiDAR technology have revealed that pre-Columbian civilizations in the Amazon were much more populous and sophisticated than previously thought. A research published in the journal Nature showed that the Aquiry, an ancient civilization in the current state of Acre, may have reached three million inhabitants and built 30 thousand geoglyphs about 2 thousand years ago. Over the past two decades, different studies have revolutionized population estimates for the Amazon, demonstrating that these peoples possessed advanced levels of agriculture and architecture that challenge previous conceptions about the region.
