Rare Mushroom Causes Unique Hallucinations of Tiny People, Scientists Seek Explanation

A rare mushroom called Lanmaoa asiatica has been found to induce unusual hallucinations of tiny, colorful, and detailed human-like figures that appear in the real environment and behave playfully or sometimes disturbingly. This phenomenon, reported mainly in parts of China, affects about 90% of people who consume the mushroom insufficiently cooked. Unlike typical psychedelics, the hallucinations do not alter colors or distort reality but add these miniature figures into the existing world. The effects begin 12 to 24 hours after ingestion and can last several days, making this experience unique and still unexplained scientifically.

Colin Domnauer, the lead researcher, told Live Science that DNA sequencing confirmed the mushroom causes similar cases in both China and the Philippines. However, the active compound responsible remains unidentified and is likely a novel substance unknown to science. Researchers believe this discovery could deepen understanding of human perception and hallucinations but caution that unraveling the mechanism will take many years.

In unrelated research, physicists have explained the spiral shape of animal feces, a phenomenon noted by Charles Darwin over a century ago. The coiling shape results from a combination of muscle movement, material viscosity, and the height from which the feces fall, following the rope coiling theory.

Finally, scientists at the University of Pennsylvania are exploring the use of oysters as natural water filters in space missions. They aim to develop a closed system where marine animals recycle water, produce food, and improve air quality for astronauts. This innovative approach could address long-term space travel challenges and open new research avenues in marine biology applied to space environments.
