How are scientists able to crack fundamental questions about nature and life? How does math make the complex cosmos understandable? In this episode, the physicist Nigel Goldenfeld and co-host Steven Strogatz explore the deep foundations of the scientific process.

European beech trees more than 1,500 kilometers apart all drop their fruit at the same time in a grand synchronization event now linked to the summer solstice.

The evolutionarily ancient part of the brain that controls breathing and heart rate also regulates the immune system — a discovery about the brain-body axis made by experts on taste.

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.

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.

To calculate the amount of carbon stored inside peatlands, researchers developed a unified theory of “bog physics” applicable around the world.

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.

New experiments reveal how the brain chooses which memories to save and add credence to advice about the importance of rest.

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.
