The Molecular Bond That Helps Secure Your Memories
How do memories last a lifetime when the molecules that form them turn over within days, weeks or months? An interaction between two proteins points to a molecular basis for memory.
AI Is Nothing Like a Brain, and That’s OK
The brain’s astounding cellular diversity and networked complexity could show how to make AI better.
How a Biofilm’s Strange Shape Emerges From Cellular Geometry
Micro decisions can have macro consequences. A soft matter physicist reveals how interactions within simple cellular collectives can lead to emergent physical traits.
Touch, Our Most Complex Sense, Is a Landscape of Cellular Sensors
Every soft caress of wind, searing burn and seismic rumble is detected by our skin’s tangle of touch sensors. David Ginty has spent his career cataloging the neurons beneath everyday sensations.
Intelligence Evolved at Least Twice in Vertebrate Animals
Complex neural pathways likely arose independently in birds and mammals, suggesting that vertebrates evolved intelligence multiple times.
The Mysterious Flow of Fluid in the Brain
A popular hypothesis for how the brain clears molecular waste, which may help explain why sleep feels refreshing, is a subject of debate.
How Metabolism Can Shape Cells’ Destinies
A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life.
How Did Multicellular Life Evolve?
One of the most important events in the history of life on Earth was the emergence of multicellularity. In this episode, Will Ratcliff discusses how his snowflake yeast models provide insight into what drove the transition from single-celled to multicellular organisms.
A New, Chemical View of Ecosystems
Rare and powerful compounds, known as keystone molecules, can build a web of invisible interactions among species.
