Brain cells activated by stress may also give you a bad night’s sleep
Stress can influence the number of times we wake during the night Tero Vesalainen/Alamy Stress can cause people to frequently wake up at night, and a newly identified brain pathway in mice may explain why. If a similar pathway exists in humans, it could lead to new ways of improving sleep quality. While short arousals…
AI made from living human brain cells performs speech recognition
Brain organoids growing in a Petri dish Science Photo Library / Alamy Balls of human brain cells linked to a computer have been used to perform a very basic form of speech recognition. The hope is that such systems will use far less energy for AI tasks than silicon chips. “This is just proof-of-concept to…
Marmosets swap brain cells with their siblings
Marmoset siblings share many things – including brain cells Werner Layer/ Alamy A large number of cells within the brains of marmosets actually come from their siblings, potentially influencing their behaviour – and the same may be true of human fraternal twins. We already know that marmosets, small monkeys native to South America, carry their…
