Brain waves detected in mini-brains grown in a dish

Scientists have created miniature brains from stem cells that developed functional neural networks. Despite being a million times smaller than human brains, these lab-grown brains are the first observed to produce brain waves ...

Cyborg organoids offer rare view into early stages of development

What happens in the early days of organ development? How do a small group of cells organize to become a heart, a brain, or a kidney? This critical period of development has long remained the black box of developmental biology, ...

Organoids reveal inflammatory processes in chlamydia infections

For a long time, researchers were only able to examine human cells infected with bacteria by using cancer cell lines. However, these transformed cells often give a false impression of the infection process. Fallopian tube ...

Chimpanzee 'mini-brains' hint at secrets of human evolution

At some point during human evolution, a handful of genetic changes triggered a dramatic threefold expansion of the brain's neocortex, the wrinkly outermost layer of brain tissue responsible for everything from language to ...

Scientists use RFID chips to track biological samples

Radio frequency identification (RFID) chips are used today for everything from paying for public transit to tracking livestock to stopping shoplifters. But now, researchers in the U.S. and Japan want to use them for something ...

New lung 'organoids' in a dish mimic features of full-size lung

New lung "organoids"—tiny 3-D structures that mimic features of a full-sized lung—have been created from human pluripotent stem cells by researchers at Columbia University Medical Center (CUMC). The team used the organoids ...

Growing a smarter model for brain research in space

Researchers studying neurological diseases face several daunting challenges. For one thing, these conditions may take years or even decades to develop. On top of that, experimenting on the brains of healthy human beings simply ...
