In a quiet summer garden, a caterpillar perches on a branch, munching serenely on leaves. A moment later it freezes. It senses danger — and just in time. From behind, a wasp approaches, sizing up its prey.

Old age and forgetfulness seem to go hand in hand. But my colleagues and I found that memories actually becomes less precise, not entirely forgotten. Our study, published in the journal Cerebral Cortex, shows how the brain blends related experiences as you age rather than replaying the exact one you need.

Taxi and ambulance drivers are less likely than workers in almost any other job to die of Alzheimer’s disease. That was the surprising result of a 2024 study examining the death certificates of nearly 9 million people in the U.S.

These findings stopped me in my tracks because those two jobs rely on the same thing as my own work: maps.

“Spider-Man: Brand New Day” turns organic web production into a superpower. In the 2026 film, Tom Holland’s character, Peter Parker, begins producing webbing inside his body and shooting it from his wrists, rather than firing synthetic web fluid from the wrist-mounted mechanical web-shooters he used in earlier films. The switch transforms a familiar superhero technology into a biological ability and highlights the spectacular properties of real spider silk.

Current therapies for Parkinson’s disease and related conditions primarily treat symptoms but don’t stop the underlying process causing the disease.

Increasing evidence suggests that toxic clumps of proteins called alpha-synuclein are among the primary drivers of damage to neurons. My team and I developed a synthetic molecule that can block these proteins from clumping and spreading in the brains of mice, ultimately reducing symptoms of disease.
