Brain-reading implants turn thoughts into speech
In this episode:00:47 The brain-computer interfaces that help restore communicationPeople with certain neurological conditions can lose the ability to speak as a result of facial paralysis. This week, two teams demonstrate the potential of devices called brain-computer interfaces to help people in these situations communicate. These interfaces work by identifying the brain activity associated with the intent to say words, and converting this activity into speech-related outputs, such as text or audio. Both devices show marked improvements compared with previous interfaces, and show that the technology could represent a way...

Neurodevelopmental Effects of Antenatal IV Magnesium Sulfate Between 30-34 Weeks' Gestation
Magnesium sulfate is widely recommended for neuroprotection in pregnancies at risk of preterm delivery. However, the optimal gestational age for use is unclear. JAMA Associate Editor Melissa Simon, MD, MPH, and Caroline Crowther, MD, Liggins Institute, University of Auckland, discuss the use of magnesium sulfate at different gestational ages and potential benefit vs harms as reflected in the MAGENTA Trial.

Audio long read: Lab mice go wild — making experiments more natural in order to decode the brain
Neuroscientists are creating more naturalistic experiments that they hope will provide a more nuanced understanding of animal — and human — behaviour.These set-ups differ from the classic laboratory experiments that have been used for decades, and may help in the understanding of behaviours such as escaping a predator or finding scarce food. By studying these natural actions, scientists are hoping to glean lessons about the brain and behaviour that are more holistic and more relevant to everyday activity than ever before.This is an audio version of our Feature: Lab mice go wild: making experiments more natural in order...

Basics of Neurotransmitters (BS 210)
click image to play episode, right click to download
This episode is our first review of neurotransmitters since episode 8 way back in 2007. We start with some basics of neuron function and brain anatomy, but the meat of the episode is a discussion of neurotransmitters and how they work. The key idea is that a simple molecule, such as dopamine, can have a wide variety of effects because of the existence of multiple receptors.This episode is appropriate for listeners of all backgrounds, but might be a little challenging for new listeners. It will be a review episode for longtime liste...

The AI special issue, adding empathy to robots, and scientists leaving Arecibo
Science’s NextGen voices share their thoughts on artificial intelligence, how to avoid creating sociopathic robots, and a visit to a historic observatory as researchers pack their bags
As part of a Science special issue on finding a place for artificial intelligence (AI) in science and society, Producer Kevin McLean shares voices from the next generation of researchers. We hear from students about how they think human scientists will still need to work alongside AI in the future.
Continuing the AI theme, we learn about instilling empathy to get better decisions from AI. Researcher Leonardo Christov-Moore, a neu...

ChatGPT can write a paper in an hour — but there are downsides
In this episode:00:23 Using ChatGPT to generate a research paper from scratchA pair of scientists have produced a research paper in less than an hour with the help of the generative artificial intelligence (AI) ChatGPT. The aim of this exercise was to explore the technology’s ability to act as a research ‘co-pilot’ and spark debate about its use. While AI tools like ChatGPT have the potential to speed up research, it is still unclear what role they should play in research.Nature News: Scientists used ChatGPT to generate an entire paper from scratch — but is it any good?06:28 Last week saw the world’s hottest day ...

Do octopuses dream? Neural activity resembles human sleep stages
In this episode:00:46 Inside the brains of sleeping octopusesResearchers have probed the brains of octopuses and confirmed previous reports suggesting that these invertebrates have a two-stage sleep cycle similar to that seen in many vertebrates. The team suggests this system may have evolved independently in the two groups, as there are millions of years of evolutionary history between them. However, despite its presumed importance, it is a mystery why this system exists at all.Research article: Pophale et al.Nature Video: Do octopuses dream?

"The Entangled Brain" with Luiz Pessoa (BS 209)
Luiz Pessoa; L click to play, R click to download
This month's episode of Brain Science is an interview with Luiz Pessoa, author of The Entangled Brain: How Perception, Cognition, and Emotion Are Woven Together.This is Pessoa's first book aimed at a general audience and it provides a concise overview of our current understanding of basic brain function. However, he also explains the limitations of the traditional modular view of the brain. A key take home point is that emotion and cognition are deeply intertwined at every level.

What IBM's result means for quantum computing
In this episode:00:47 How to make quantum computers ready for real world applicationsQuantum 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 th...

A brain circuit for infanticide, in mice
In this episode:00:46 The mouse brain circuit controlling infanticidal behaviourIn mammals, infanticide is a relatively common behaviour, but not a default one. For example, virgin female mice will often kill young produced by other females, but this behaviour disappears when they become mothers themselves. To understand this switch, researchers have identified a brain circuit associated with infanticidal behaviour that gets switched off after mice give birth. They hope that by better understanding this circuit it could inform why animals engage in such behaviours.Research article: Mei et al.Research Briefing: A battle bet...
