A family portrait of human brain cells

A cell census provides information on the source of human brain specialization

The brain is composed of multiple regions associated with distinct functions, which have become further specialized in the human lineage. To define how this specialization is implemented, how it arises during development, and how it has emerged over the course of human evolution, a detailed understanding of the cells that make up the human brain is required.

Science: Brain Cells Wired To The Matrix, DeepMind Search Engine, Omicron

In a step towards creating intelligent cyborg brains, Cortical Labs in Melbourne have trained lab-grown brain organoids to play a classic 1970s video game. The team explains how the brain cells live in a Matrix-like, simulated world, where all they know is Pong. 

And there’s more AI news, as the team digs into DeepMind’s invention of a ‘search engine’ style supercomputer, one much smaller than its competitors. The team discusses sleep, and how manipulating the hypnagogic phase of sleep can lead to bursts of creativity. As the holiday season approaches, Omicron shows no signs of letting up, so the team brings you up to speed on what we know so far. And they bring two bird related stories, one about the superpowers of zebra finches and the other about the link between personality types and feather colours in turkeys. On the pod are Rowan Hooper, Penny Sarchet, Michael Le Page, Clare Wilson and Matt Sparkes. To read about these stories and much more, subscribe at newscientist.com/podcasts.

Science Podcast: How Brain Cells Use Energy, Lobster Bellies & Red Meat

Ultra-precise measurements connect brain activity and energy use in individual fruit-fly neurons.

In this episode:

00:45 How brain cells use energy

A team of researchers have looked in individual fruit-fly neurons to better understand how energy use and information processing are linked – which may have important implications for future fMRI studies in humans.

Alzheimer’s Disease: ‘How It Starts & Progresses’

The first event in our Lab Notes online series features two researchers from our South Coast Network Centre talking about early brain changes in Alzheimer’s. Dr Karen Marshall shares her work studying how waste disposal and recycling systems in nerve cells cause damage in Alzheimer’s disease, and whether there could be ways to rescue cells from this. Dr Mariana Vargas-Caballero speaks about her research into brain cell connections and how they are affected in Alzheimer’s. The event is chaired by Dr Katy Stubbs from Alzheimer’s Research UK, and also features a Q&A session.
