The Year in Biology
While the study of the SARS-CoV-2 virus was the most urgent priority, biologists also learned more about how brains process information, how to define individuality and why sleep deprivation kills.
Catherine Dulac Finds Brain Circuitry Behind Sex-Specific Behaviors
Catherine Dulac is overturning preconceptions about “male” and “female” instincts and opening new avenues to treating postpartum depression.
Deep Neural Networks Help to Explain Living Brains
Deep neural networks, often criticized as “black boxes,” are helping neuroscientists understand the organization of living brains.
The Epigenetic Secrets Behind Dopamine, Drug Addiction and Depression
New research links serotonin and dopamine not just to addiction and depression, but to the ability to control genes.
Mitochondria May Hold Keys to Anxiety and Mental Health
Research hints that the energy-generating organelles of cells may play a surprisingly pivotal role in mediating anxiety and depression.
Spreading the Word on a Possible Alzheimer’s Treatment
Neuroscientists could use brain waves to spur immune cells into action against the disease — but the process is almost too fantastic to believe.
The Brain Reshapes Our Malleable Senses to Fit the World
How does experience alter our perceptions? This adapted book excerpt from We Know It When We See It describes how the brain’s visual system rewires itself to make the best use of its neural resources.
Hidden Computational Power Found in the Arms of Neurons
The dendritic arms of some human neurons can perform logic operations that once seemed to require whole neural networks.
Longevity Linked to Proteins That Calm Overexcited Neurons
New research makes a molecular connection between the brain and aging — and shows that overactive neurons can shorten life span.
