A Neurobiologist Thinks Big — and Small
By developing new tools for visualizing subcellular structure and activity in molecular detail, Ed Boyden advances on his goal of understanding how the brain works.
Light-Triggered Genes Reveal the Hidden Workings of Memory
Nobel laureate Susumu Tonegawa’s lab is overturning old assumptions about how memories form, how recall works and whether lost memories might be restored from "silent engrams."
Why the First Drawings of Neurons Were Defaced
Every exquisite drawing by Santiago Ramón y Cajal, the founder of modern neuroscience, is marred by a curious mark. Here is the little-known story behind it.
The Oldest Mini-Brains Have Lifelike Young Cells
"Organoid" brain tissue models grown in a lab for two years can help scientists study a critical period of development just before and after birth.
Mini-Brains Go Modular
To create a good living replica of the human brain, your best hope may be to let “organoid” components assemble it for you.
Can Microbes Encourage Altruism?
If gut bacteria can sway their hosts to be selfless, it could answer a riddle that goes back to Darwin.
A Theory of Reality as More Than the Sum of Its Parts
New math shows how, contrary to conventional scientific wisdom, conscious beings and other macroscopic entities might have greater influence over the future than do the sum of their microscopic components.
Researchers Tap a Sleep Switch in the Brain
Powerful new experiments have uncovered some of the molecular underpinnings of sleep.
Infant Brains Reveal How the Mind Gets Built
Is the brain a blank slate, or is it wired from birth to understand the world?
