How humans judge AI's advice—and why we're terrible at knowing when to trust it

Log in to share

When an AI suggests something, we often look at it the way a jury looks at an expert witness: we trust the confident tone more than the actual accuracy.

This means as we integrate AI into workplaces and hospitals, we need to design interfaces that help us spot bad advice, because our instincts are unreliable judges.

When reality is too messy: Teaching AI to learn physics from noisy, real-world data

Log in to share

Most simulation models learn from pristine lab conditions, but real proteins and weather systems are chaotic, wobbling between states. This work uses something already hiding in your data—covariance patterns—as a geometric compass to keep the AI's internal map accurate even when the world is blurry.

This means we can build faster, more reliable computer models of complex systems (drug interactions, climate patterns) from the kind of imperfect data scientists actually have.

Your immune cells might be your secret endurance weapon

Log in to share

When you exercise, it's not just your muscles that toughen up—your immune cells get a pep talk, and they're apparently whispering back encouragement to help you push harder.

This means the next breakthrough in athletic performance or fatigue therapy might come from understanding how immune cells talk to your brain during exercise, not just from muscle training.
