How cells recycle damaged mitochondria in middle age may be critical for brain health Mitochondria play an essential role in maintaining cellular health. When damaged, they are removed through a recycling process called mitophagy, which is crucial for the function of long-lived cells, especially in the brain. Impaired mitophagy has been strongly associated with neurodegenerative disorders like Alzheimer's and Parkinson's disease, making it a critical focus for drug discovery and therapeutic innovation.

Distinct neural circuits mediate anti-anxiety and hallucination-like effects of psychedelics, research reveals New research suggests that it could be possible to separate treatment from hallucinations when developing new drugs based on psychedelics. The anti-anxiety and hallucination-inducing qualities of psychedelic drugs work through different neural circuits, according to research using a mouse model. The work is published in Science.

Q&A: Generating data from neurons to teach AI the rules of the brain The 2024 Nobel Prizes in physics and chemistry were seen as a sweep for artificial intelligence (AI) tools which, at their conception, were inspired by neuroscience. By imitating the behavior of human brain cells, machine-learning algorithms are accelerating our understanding of basic biology, with technologies such as Google DeepMind's AlphaFold 3 making it possible to predict the structure of proteins or how they might interact with potential drugs.

'It's my brain's fault': Why teenagers often make less than optimal decisions Adults exhibit a general tendency to make better decisions than adolescents, and this improvement drives an increase in specific and more sophisticated choice behaviors, according to a study published November 14 in PLOS Biology by Vanessa Scholz and Lorenz Deserno from the University of Würzburg, Germany, and colleagues.
