Can Psychedelics Improve Mental Health?
Research suggests that psychedelic drugs can reopen critical periods of brain development to create opportunities for re-learning and psychological healing. In this episode, co-host Janna Levin speaks with Gül Dölen, a neuroscientist studying the therapeutic potential of psychedelic substances.
Most Life on Earth Is Dormant, After Pulling an ‘Emergency Brake’
Many microbes and cells are in deep sleep, waiting for the right moment to activate. Biologists discovered a widespread protein that abruptly shuts down a cell’s activity — and turns it back on just as fast.
Simple Equation Predicts the Shapes of Carbon-Capturing Wetlands
To calculate the amount of carbon stored inside peatlands, researchers developed a unified theory of “bog physics” applicable around the world.
What Happens in the Brain to Cause Depression?
Drugs that target the neurotransmitter serotonin have long been prescribed to treat depression. Now the spotlight is turning to other aspects of brain chemistry. In this episode, the neuropharmacologist John Krystal shares findings that are overturning our understanding of depression.
Electric ‘Ripples’ in the Resting Brain Tag Memories for Storage
New experiments reveal how the brain chooses which memories to save and add credence to advice about the importance of rest.
How ‘Idle’ Egg Cells Defend Their DNA From Damage
How do immature egg cells maintain genetic quality for decades before they mature? Scientists find unusual safeguards in this quiescent cell that may inform research into fertility.
New AI Tools Predict How Life’s Building Blocks Assemble
Google DeepMind’s AlphaFold3 and other deep learning algorithms can now predict the shapes of interacting complexes of protein, DNA, RNA and other molecules, better capturing cells’ biological landscapes.
The Mystery of the Missing Multicellular Prokaryotes
Why have bacteria never evolved complex multicellularity? A new hypothesis suggests that it could come down to how prokaryotic genomes respond to a small population size.
What Does Milk Do for Babies?
Human nutrition begins with milk, but the wondrous biofluid does much more than feed babies. In this episode, co-host Steven Strogatz speaks with molecular nutritionist Elizabeth Johnson about her research into the impact of human milk on a healthy microbiome.
