Stem cell-derived 'organoids' help predict neural toxicity

A new system developed by scientists at the Morgridge Institute for Research and the University of Wisconsin-Madison may provide a faster, cheaper and more biologically relevant way to screen drugs and chemicals that could ...

Tiny spheres of human cells mimic the brain, researchers say

The human brain is a highly organized, three-dimensional mass of cells responsible for our every move, thought and emotion. Snugly housed in the bony confines of the skull, it's also relatively inaccessible, making it difficult ...

New advancements in 3D designs for neural tissue engineering

It is well known that neurological diseases and injuries pose some of the greatest challenges in modern medicine, with few if any options for effectively treating such diagnoses, but recent work suggests a unique approach ...

A 'Clear' choice for clearing 3-D cell cultures

Because Brown University biomedical engineering graduate student Molly Boutin needed to study how neural tissues grow from stem cells, she wanted to grow not just a cell culture, but a sphere-shaped one. Cells grow and interact ...

Aging really is 'in your head'

Among scientists, the role of proteins called sirtuins in enhancing longevity has been hotly debated, driven by contradictory results from many different scientists. But new research at Washington University School of Medicine ...

Neural simulations hint at the origin of brain waves

For almost a century, scientists have been studying brain waves to learn about mental health and the way we think. Yet the way billions of interconnected neurons work together to produce brain waves remains unknown. Now, ...
