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.

Technology: Caltech In 2021 – The Year In Review

In January, researchers developed a cage-like vaccine platform called a mosaic nanoparticle that could help protect against multiple strains of coronavirus; obtained new insights into human decision-making using AI-trained networks playing video games; learned how tiny plants changed the planet nearly half a billion years ago; and studied chaotic systems using a camera that can take up to 70 trillion frames per second.

Meanwhile, the Institute announced that it would remove the names of known eugenics proponents from its buildings, honors, and assets.

February saw the historic landing of NASA’s Mars rover Perseverance on the Red Planet. The 2,263-pound rover, designed and operated by JPL, which Caltech manages for NASA, will spend two years investigating Mars’s Jezero crater, and will collect and cache samples of rocks and sediment for recovery by a subsequent mission.

Here on Earth, seismologists worked with optics experts to develop a method to use existing underwater telecommunication cables to detect earthquakesphysicists advanced the use of exotic materials for future ultrafast computers; and engineers perfected methods to place molecules in particular orientations at specific locations—work that paves the way for the integration of molecules with computer chips.

In March, Caltech researchers announced a non-invasive method that uses ultrasound to read and interpret brain activity related to the intent to move, a major step toward the creation of noninvasive brain–machine implants that can restore movement to paralyzed individuals; located Mars’s missing water; described a long-sought solution to “one of the most stubborn problems in math”; and explained how bacteria evolve resistance to antibiotics and how antibiotics help bacteria eat when nutrients are scarce.

Science: Pluto’s Giant Ice Patterns, Pamplona’s Bull-Running Crowd Dynamics

An explanation for giant ice structures on Pluto, and dismantling the mestizo myth in Latin American genetics.

In this episode:

00:46 The frozen root of Pluto’s polygonal patterns

In 2015, NASA’s New Horizons probe sent back some intriguing images of Pluto. Huge polygonal patterns could be seen on the surface of a nitrogen-ice ice filled basin known as Sputnik Planitia. This week, a team put forward a new theory to explain these perplexing patterns.

Research article: Morison et al.

06:15 Research Highlights

How Pamplona’s bull-running defies the dynamics of crowd motion, and self-healing microbial bio-bricks.

Research Highlight: Running of the bulls tramples the laws of crowd dynamics

Research Highlight: It’s alive! Bio-bricks can signal to others of their kind

09:06 How the mixed-race ‘mestizo’ myth has fostered discrimination

The term ‘mestizo’ emerged during the colonial period in Latin America to describe a blend of ethnicities – especially between Indigenous peoples and the Spanish colonizers. But this label is a social construct not a well-defined scientific category. Now researchers are challenging the mestizo myth, which they say is harmful and has a troubling influence on science.
