00:48 How hunger, hormones and aggression interact in mouse brains

Researchers have uncovered the neural mechanisms that underlie an aggressive behaviour in mice prompted by hunger and hormonal state. Virgin female mice can become aggressive towards mouse pups when they are food deprived, but it seems that the relevant amounts of pregnancy hormones, oestrogen and progesterone, also played a role. By investigating the neurons involved, neuroscientists showed how hunger and hormones are integrated by the brain to lead to aggressive behaviour. This could help researchers understand more about how multiple stimuli are interpreted by the brain, something much harder to study than single stimulus effects.

11:53 What generative AI could mean for higher education

Around the world, universities and students are scrambling to adapt to the use of generative AI tools such as ChatGPT. And while there is optimism that these tools could improve education, there are also concerns about the ways they could stifle independent, critical thought. We hear about the studies trying to unpick the potential impact of this new technology.
