Chronic stress is already tough on your gut—but new research suggests late-night eating could make things even worse. Scientists analyzing thousands of people found that those under high stress who also ate a large portion of their calories after 9 p.m. were far more likely to suffer from constipation and diarrhea. The combination appears to hit the gut twice, not only disrupting digestion but also reducing the diversity of beneficial gut bacteria.

For decades, psychologists have debated whether the human mind can be explained by one unified theory or must be broken into separate parts like memory and attention. A recent AI model called Centaur seemed to offer a breakthrough, claiming it could mimic human thinking across 160 different cognitive tasks. But new research is challenging that bold claim, suggesting the model isn’t truly “thinking” at all—it’s just memorizing patterns.

The body’s “killer” T cells don’t just attack—they strike with astonishing precision, forming a tiny, highly organized contact zone that lets them destroy dangerous cells without harming their neighbors. Now, scientists have captured this process in unprecedented detail, revealing a hidden world of molecular choreography.

A troubling new study from MIT reveals that a common environmental contaminant, NDMA—found in polluted water, certain medications, and even processed foods—may pose a far greater cancer risk to children than adults. In experiments with mice, young animals exposed to the chemical developed significantly more DNA damage and cancer, despite experiencing the same initial exposure as adults. The key difference lies in how rapidly children’s cells divide, which turns early DNA damage into dangerous mutations much more easily.

Researchers have found an enzyme that can turn fragile drug molecules into durable ring shapes. This could help medications like Ozempic last longer and work more effectively. The process is simpler and more precise than traditional methods, even for complex drugs. It may open the door to stronger, longer-lasting treatments.

Scientists are making a major leap toward freezing organs for future use without damaging them. A new study reveals that one of the biggest obstacles—cracking during ultra-cold preservation—can be reduced by carefully tuning the temperature at which tissues enter a glass-like state. This breakthrough builds on recent successes in cryopreserved organ transplants and could bring the long-imagined idea of “banking” organs for later use much closer to reality.

A major new study finds that living in pesticide-heavy environments could raise cancer risk by up to 150%, even when the chemicals are considered “safe” on their own. The research suggests these mixtures may silently damage cells years before cancer appears.
