Summary: Researchers uncovered how certain brain cells enhance our ability to maintain and focus on short-term memories. Their study highlights a new type of neuron, dubbed PAC neurons, which coordinate the activity of memory-specific neurons without storing any information themselves.

These findings were derived from the brain activity recordings of epilepsy patients during memory tasks, providing novel insights into how working memory functions. Understanding these mechanisms may lead to improved treatments for disorders like Alzheimer’s and ADHD, where such cognitive functions are impaired.

Nobel Prize-winning molecular biologist Venki Ramakrishnan sat down with ABC News Live to discuss the science and ethics of extending the human lifespan.

In his new book, “Why We Die: The New Science of Aging and the Quest for Immortality,” Ramakrishnan explains why we may not want to lengthen our lives much longer.

Ramakrishnan’s thought-provoking argument is that a society where people lived for hundreds of years could potentially become stagnant, as it would consist of the same group of people living longer, raising important questions about societal dynamics and progress.

As many CEOs gloat over the idea of replacing their human workers with AI, some of them are now starting to fear that they, too, may be on the chopping block.

Per a new report from the IT consulting firm AND Digital which surveyed hundreds of business leaders in the US, the UK, and the Netherlands, 43 percent of respondents said they believed AI could take their job as CEO.

Denizens of the C-suite aren’t making a strong case for keeping their positions, either. Embarrassingly, nearly that exact same proportion — 45 percent — admitted to secretly making major business decisions “based on data and information obtained using ChatGPT.” Strong evidence, perhaps, that maybe replacing CEOs with AI isn’t such a bad idea after all.
