Scientists have taken a major step toward treating spinal cord injuries that cause paralysis. In lab dishes, researchers at Northwestern University grew tiny organoids of the human spinal cord. Then, ...

Organoids modeled on the structure of the human spinal cord have been shown to match the behavior of an injured spine. Now, a treatment that has worked well in mice has been applied to the organoids, ...

Assessing the toxicity of food contaminants—including carcinogenic potential—is a major challenge in evaluating the risks associated with exposure. In recent years, as part of efforts to reduce animal ...

A new ‘pop-up’ device developed by Professor John Rogers lets scientists map and manipulate activity in human neural ...

Brain organoids have come a long way. These mini-brains, at most the size of a pea, are made from stem cells or reprogrammed skin cells and churned inside a bioreactor full of nutrients. With ...

Neurites include axons, which are often severed during spinal cord injuries. When axons are cut, communication between ...

Researchers have developed miniature 3D human colons enriched with immune cells, showcasing potential advancements in addressing conditions like inflammatory bowel disease (IBD) and cancer. The ...

Mini human brains, grown from stem cells and implanted into living mice, have for the first time been shown to respond to things the mice were seeing. Scientists were able to watch the responses in ...

A microscopic model of the human liver to study the effects of different food contaminants. The spherical model, measuring 0.3 mm in diameter, includes the four cell types found in the human liver.

Assessing the toxicity of food contaminants—including carcinogenic potential—is a major challenge in evaluating the risks associated with exposure. In recent years, as part of efforts to reduce animal ...
