This week on Behind the Labs, we’re diving into five studies that challenge what we think we know about the brain, the body, and even what makes us human.
Let’s start with something almost philosophical. Researchers showed that a bonobo named Kanzi can track imaginary objects in controlled experiments — like pretend juice being poured into a cup. He consistently identified where the “imaginary” object was, even after the cups were moved. That’s a big deal because imagination — the ability to mentally represent something that isn’t physically there — has long been considered uniquely human. If apes share even part of that ability, it suggests imagination may have evolutionary roots going back millions of years.
Next, shifting to human health — a large U.S. study found that people with the highest intake of ultra-processed foods had a 47% higher risk of cardiovascular disease. These foods now make up about 60% of adult diets in the U.S. The concern isn’t just calories — it’s how heavily altered these foods are and how they may drive inflammation and metabolic dysfunction. It raises the question: are we engineering convenience at the cost of long-term cardiovascular health?
On a more specific nutrition note, another study found that older adults who don’t consume enough lycopene — the antioxidant found in tomatoes — have significantly higher odds of severe gum disease. What’s interesting is that the protective effect varied by race and sex, pointing to deeper health disparities that diet alone may not fully explain.
In mental health research, the most comprehensive review ever conducted on ADHD treatments confirmed that medication remains the most evidence-supported intervention for both children and adults, with cognitive behavioral therapy strongly supported for adults. Many alternative approaches showed weaker evidence. The researchers even launched an interactive platform to help patients and clinicians navigate treatment options more transparently — which speaks to how overwhelming and contradictory mental health advice can feel.
Then there’s AI in medicine. A new system called Prima can analyze brain MRIs in seconds with up to 97.5% accuracy, automatically flagging urgent conditions like stroke. It integrates imaging with patient history — almost like a radiologist co-pilot. In a health system strained by backlogs and specialist shortages, that kind of speed could genuinely change outcomes.
