A team of University of Wisconsin–Madison scientists has developed the first 3D-printed brain tissue that can grow and function like typical brain tissue.

It’s an achievement with important implications for scientists studying the brain and working on treatments for a broad range of neurological and neurodevelopmental disorders, such as Alzheimer’s and Parkinson’s disease.

“This could be a hugely powerful model to help us understand how brain cells and parts of the brain communicate in humans,” says Su-Chun Zhang, professor of neuroscience and neurology at UW–Madison’s Waisman Center. “It could change the way we look at stem cell biology, neuroscience, and the pathogenesis of many neurological and psychiatric disorders.”

The rare condition posterior cortical atrophy (PCA) involves strange, troubling issues with vision and spatial awareness – including difficulty judging distances, seeing movement, and recognizing objects – and a new study highlights its close relationship to Alzheimer’s disease in more detail than ever before.

PCA and Alzheimer’s have long been linked with each other, because they share a lot of the same pathological changes in the brain. However, the rarity of PCA has made it hard for researchers to fully assess it in relation to Alzheimer’s.

To address that, an international team of researchers analyzed data on 1,092 individuals with PCA, finding that it was a very strong predictor for Alzheimer’s: in 94 percent of cases, tell-tale Alzheimer’s brain changes were observed, and were most likely contributing to PCA.

Summary: Researchers developed the world’s first 3D-printed brain tissue that grows and behaves similarly to natural brain tissue, marking a significant leap forward for neurological and neurodevelopmental disorder research.

This novel 3D-printing technique uses a horizontal layering approach and a softer bio-ink, allowing neurons to interconnect and form networks akin to human brain structures.

The ability to precisely control cell types and arrangements provides unparalleled opportunities to study brain functions and disorders in a controlled environment, offering new avenues for drug testing and understanding brain development and diseases like Alzheimer’s and Parkinson’s.

“Connectomes” among species provide chip-design inspiration.

The recently published tech policy document by the Ministry of Industry and Information Technology reflects their dedication to fostering innovation and development in future industries. The roadmap emphasizes the importance of forward-looking planning, policy guidance, and cultivating new quality productive forces to support the country’s aspirations for global technological leadership.

The race for supremacy in brain-computer interfaces intensifies as the world watches China’s technological journey unfold. With Neuralink marking its milestones, China’s bold ambitions signal a new era of competition in the ever-evolving landscape of cutting-edge technologies.

The question now is not just about who will lead the race but what groundbreaking innovations lie ahead for humanity.

Some human neurons take years to reach maturity; an epigenetic ‘brake’ could be responsible.

I believe that the nanotransfection using internal biocomputing will change psychiatric problems because it will physically repair problems with biocomputing rather chemical based computers. Also this could heal the software components aswell of the mind aswell.

Millions of Americans experience symptoms of a mental health condition each year, and the number of people seeking care is trending upward. While a mental health diagnosis may impact an individual’s daily life, it can also have a ripple effect across families, communities and even economies.

Here’s a closer look at the current state of mental health, including how many people experience mental health conditions and which populations are most at risk.

Plants don’t have eyes or brains. How do they know where light is coming from? New research shows how seedlings “see” with their whole bodies.

A mutant seedling revealed how plant tissues scatter incoming light, allowing plants to sense its direction and move toward it.

Evolutionary biologists at Johns Hopkins Medicine report they have combined PET scans of modern pigeons along with studies of dinosaur fossils to help answer an enduring question in biology: How did the brains of birds evolve to enable them to fly?

The answer, they say, appears to be an adaptive increase in the size of the cerebellum in some fossil vertebrates. The cerebellum is a brain region responsible for movement and motor control.

The research findings are published in the Jan. 31 issue of the Proceedings of the Royal Society B.
