Google’s AI Overviews and AI Mode are changing how people find information, putting the clicks, revenue, and future of online publishing at risk.

Human cancer cells, specifically HeLa cells, with DNA stained blue and cyan. The central and rightmost cell are in interphase. The cell on the left is going through mitosis and its chromosomes have condensed.

A detailed single-cell study shows how pancreatic tumors evolve, evade immunity, and become more aggressive—and points to MYC as a possible target.

A new ASPREE analysis links low-dose aspirin to lower dementia risk in older adults with platelet-related genes, but major bleeding also increased.

A reverse engineer says Samsung’s Tizen TVs process audio, screenshots, and viewing data for targeted ads, raising fresh privacy concerns.

Fruit bodies of the hallucinogenic mushroom Psilocybe semilanceata (Fr.) Kumm. Specimens photographed in Sweden.

DNA evidence links a Chinese and Philippine mushroom to vivid visions of tiny people, but the compound behind the bizarre hallucinations remains unknown.

This diagram represents the biosynthetic and metabolic pathways by which phytocannabinoids (e.g., CBD, THC, CBN) are created in the cannabis plant. Starting with CBG-A, the acidic forms of certain phytocannabinoids are generated via enzymatic conversion. From there, decarboxylation (i.e., combustion or heat) yields the most well-known metabolites present in the cannabis plant. CBN is unique in that it does not arise from a pre-existing acidic form, but rather is generated through the oxidation of THC.

A new mouse study links repeated CBN exposure to tolerance and withdrawal signs, raising fresh questions about cannabis sleep gummies and long-term safety.
