Human ‘mini brains’ mesh with mouse minds to form active neural circuits The technique opens new possibilities for investigating neurological conditions, from autism to dementia By Cody Cottier edited by Claire Cameron Miniature lab-grown brains, called brain organoids, open little windows into human neurodevelopment that are impossible to get by studying actual human brains. But without a blood supply or sensory input, these pea-sized neuron clusters eventually hit a developmental ceiling. And

‘Mini brains’ kept alive for years appear to age like real brains Miniature models of the human brain can be kept alive for years, allowing scientists to study neural development and brain diseases By Cody Cottier edited by Allison Parshall Lab-grown “mini brains,” called brain organoids, kind of look like navy beans—and have very little in common with a functional human brain. These tiny clumps of neural tissue are grown from stem cells and mimic the earliest stages of brain development. Scient

Birdsong follows a fundamental law of human language A fundamental law of human language has now been found in both songbirds and whales By Cody Cottier edited by Allison Parshall The twittering of songbirds may bear little resemblance to human speech, but new research on Bengalese Finches shows that their vocalizations do follow a fundamental structural principle found in all languages. Zipf’s law states that a handful of words—or, in this case, chirps, whistles and trills—occur frequently, whi

A unique cellular trick may explain octopus intelligence A newly discovered change in ribosomal RNA makes protein production more precise, potentially safeguarding these cephalopods’ complex nervous systems By Cody Cottier edited by Andrea Thompson When it comes to animal intelligence, octopuses have few rivals. Some species of the cephalopods lug coconut shells around for mobile shelter; others radically transform their bodies to mimic deadlier creatures. Almost two decades ago in Germany, a pa
Humanity’s ‘golden age’ of language may have occurred 2,000 years ago (opens the original)
Read excerpt
Humanity’s ‘golden age’ of language may have occurred 2,000 years ago During a lost ‘golden age’ of language, humans may have spoken tens of thousands of different tongues, a new study suggests By Cody Cottier edited by Allison Parshall Our planet’s inhabitants speak more than 7,000 languages, each a unique repository of knowledge, culture and history. But today’s linguistic diversity may be only the shadow of a time when humans conversed in 10 times as many tongues. For two millennia, from 1000
