Episode notes

Gull Dolan from Johns Hopkins in the US found that psychedelic effects were lasting for 48 hours to four weeks after taking a drug. He and his team identified 65 genes that seem to be involved when this critical period was open in mice. Of those, around 20% seemed to be involved in regulating something known as the extracellular matrix. This increased malleability of the brain structures could be what's behind the brain's ability to absorb more information during these critical periods.

00:47 How to make quantum computers ready for real world applications

Quantum computers have long held the promise of being able to perform tasks that classical computers can’t. However, despite this promise, there have been few applications that can only be accomplished by a quantum computer. Now though, researchers show that a quantum computer can resolve a physics problem concerning the orientation of quantum particles in a 2D material, which is difficult to accomplish with a ‘regular’ machine. They hope that this shows how quantum computers could be applied in real world research applications in the near future.

12:45 How psychedelics might work in the brain

Psychedelics are a group of drugs that affect perceptions of consciousness, and are of increasing interest in the treatment of conditions like depression, post-traumatic stress disorder, and addiction. However, a lot is unknown about how they affect the brain. Now, researchers have shown that these varied drugs may have a shared mechanism: making the brain more able to forge new connections between synapses. They hope that this will inform how best to use psychedelics in treatments.
