Scientists have found evidence using neuroimaging that the native language people speak may affect the way that their brains are wired.

Researchers from Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig analyzed and compared the brain scans of native Arabic and German speakers. The languages were selected for the reason that they are significantly different.

Their results indicate the native language of an individual can influence the connectivity between areas of their brains.

Relativity Space, a 3D-printing specialist, launched the inaugural flight of its Terran 1 rocket late on Wednesday night, which successfully met some mission objectives before failing to reach orbit.

Terran 1 lifted off from LC-16, a launchpad at the U.S. Space Force’s facility in Cape Canaveral, Florida, and flew for about three minutes. While the rocket cleared a key objective — passing the point of maximum atmospheric pressure during an orbital launch, known as Max Q — its engine sputtered and shut down early, shortly after the second stage separated from the first stage, which is the larger, lower portion of the rocket known as the booster.

Relativity launch director Clay Walker confirmed that there was an “anomaly” with the upper stage. The company said it will give “updates over the coming days” after analyzing flight data.

Scientists transplanted human cerebral organoids (“minibrains”) into rats, to better study brain disorders. The neurons grown in vivo looked more like mature human brain cells than those grown in vitro, and they made better models of Timothy syndrome. The human minibrains formed deep connections with the rat brains, received sensory information, and drove the rat’s behavior.

More on how minibrains are grown and used, and the issue of organoid consciousness: https://www.youtube.com/watch?v=u6FGq7_t3Eo.

If a free-floating brain could feel pain or ‘wake up,’ how would we know? That’s an important ethical question — and it’s one we need to ask more often as labs around the world create new organoids, or miniature human organs. To answer it we talked to Jay Gopalakrishnan at his ‘mini brain’ lab for centrosome and cytoskeleton biology in Düsseldorf, Germany.
