Can we reverse aging? A new competition puts it to the test

A Contest to Turn Back Time

A new competition is asking an unusual question: can we actually reverse aging? Teams around the world are competing against each other to develop methods that could make our bodies biologically younger. This isn't science fiction — researchers are using real scientific techniques to test whether aging can be slowed or even reversed in human cells and tissues.

Why does this matter? If scientists can figure out how to reverse aging at the biological level, it could change how we think about growing older. We're talking about potentially keeping people healthier for longer, reducing age-related diseases, and improving quality of life in our later years.

Why AI Can't Actually Think Like You

At the same time, researchers have made an important discovery about artificial intelligence (AI) — the chatbots and language models (AI systems trained to understand and generate human language) that seem so smart aren't actually reasoning the way humans do. Instead, they're following patterns they've learned from massive amounts of training data.

This matters because many people assume AI chatbots understand problems and think through solutions. In reality, they're pattern-matching machines — very sophisticated ones, but still. They can give you helpful answers, but they're not truly thinking or reasoning. Understanding this gap between what AI seems to do and what it actually does helps us use these tools more wisely and sets better expectations for what they can and cannot accomplish.
