Summary
In this episode:
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.

Research Highlight: The Arctic could go ice-free in less than a decade
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.

20:17 Briefing Chat
We discuss some highlights from the Nature Briefing. This time a study showing that the energy drink additive taurine increases the lifespans of several animals, and how much reformatting research papers is costing science.
