A recent study found increased brain activity in two dying patients, but it does not indicate consciousness. The research revealed gamma wave bursts in comatose patients with epilepsy, but no evidence these were tied to conscious experiences.

Researchers warn that mushroom gummies sold to boost brain function may contain illegal hallucinogens and other harmful ingredients, after five people, including a 3-year-old, fell ill. Testing revealed that three out of five brands contained psilocybin or psilocin, Schedule I drugs, which were not listed on the labels. This poses a public health threat, as consumers are unaware of what they are ingesting.
