Psychedelics' Mechanism Unveiled; Cancer Therapy in Crisis

Psychedelics Research Corrected; AI Advancements and Weight-Loss Drug Side Effects Also in the News

In a correction published on January 28, 2026, Nature News addressed errors in a previous article detailing the mechanism by which psychedelics elicit their effects. The original article, which focused on the role of 5-HT2A receptor-mediated Gi signaling, contained several typographical errors in its initial publication, according to the correction notice.

The correction, published online, clarified inaccuracies in the original article's presentation of superscript numbers and specific amino acid designations within the receptor's structure. The original article explored the signal transduction of 5-HT2AR and the ligand recognition mechanism.

Beyond the scientific correction, other significant developments were highlighted in the news this week. According to multiple sources, including Nature News, advancements in artificial intelligence continue to dominate headlines. Collaborations between companies like Infosys and Anthropic are underway to automate enterprise tasks. The AI Impact Summit in Delhi is also addressing AI's global impact and development.

Simultaneously, the rapidly expanding use of GLP-1 weight-loss drugs has led to the emergence of new side effects. According to Vox, demand for these drugs has more than doubled since 2024. While fatigue and nausea are common, new symptoms are being reported as more people use the medication. Dr. Sera Lavelle, a clinical psychologist, has observed these emerging side effects.
