Key cells in the brain, neurons, form networks by exchanging signals, enabling the brain to learn and adapt at incredible speed. Researchers at the Delft University of Technology in The Netherlands (TU Delft) have developed a 3D-printed brain-like environment where neurons grow similarly to a real brain.

Using tiny nanopillars, they mimic the soft neural tissue and the brain extracellular matrix fibers. This model provides new insights into how neurons form networks, as well as a novel tool to understand in future how this process may change in neurological disorders such as Alzheimer’s, Parkinson’s disease, and autism spectrum disorders.

The work is published in the journal Advanced Functional Materials.

An exploration of the idea that all true technological intelligence is inherently artificial in a sense, including the human brain. This has major implications on the Fermi Paradox and may be one of the strongest solutions of why when we search the heavens, we do not see evidence of alien life.

Sam Harris and Roger Penrose discuss the mysteries of consciousness and selfhood.

Is the Self merely an illusion?

With a free trial, you can watch the full debate NOW at https://iai.tv/video/the-divided-self-sam-harris-roger-penro…escription.

Many have sought to divide the self into separate parts. From Aristotle’s distinction between the rational and irrational self to Freud’s separation of the conscious and unconscious mind, from Kahneman’s fast and slow self to McGilchrist’s selves of the left and right brain. But critics argue it makes no sense to see the self as divided. From Descartes to Sartre, many philosophers have concluded that to be conscious is to be conscious of something and there can be no further self hiding within consciousness. After all, if there are two aspects of the self does it not require a third to oversee or combine them? Meanwhile, neuroscience has been unable to identify a self at all let alone multiple selves.

Health during pregnancy does not cause autism, according to a study of 1.1M pregnancies. Genetics and fetal complications play a much larger role, challenging long-held assumptions about autism risk factors. +.

Summary: A large study analyzing over 1.1 million pregnancies found no strong evidence that maternal health conditions during pregnancy cause autism. Instead, nearly all previously reported associations between maternal diagnoses and autism could be explained by genetic or environmental factors.

Researchers found that only fetal complications remained statistically linked to autism, suggesting these issues might be early signs rather than causes. By analyzing sibling and paternal health records, the study further ruled out many maternal conditions as contributing factors.

The findings emphasize that autism likely begins before birth due to genetic influences rather than maternal health conditions. This research may help alleviate guilt for parents and shift focus toward early diagnosis and support.

Summary: Scientists have used advanced X-ray phase-contrast tomography (XPCT) to uncover how gut health may influence Alzheimer’s disease. The study found structural changes in the gut of Alzheimer’s-affected mice, revealing abnormalities in intestinal cells, neurons, and mucus secretion.

This supports the hypothesis that harmful gut bacteria may escape into circulation, triggering brain inflammation and neurodegeneration. The findings highlight the gut-brain connection and provide a new tool for detecting early disease markers.

Researchers aim to further explore how the enteric nervous system communicates with the brain in Alzheimer’s. The study paves the way for potential new therapeutic targets based on gut health.

Random noise, such as background hubbub on a phone call, is usually thought of as unwanted interference. Now researchers at Columbia Engineering find the brain may harness unavoidable random fluctuations of its activity to perform useful computations, particularly in tasks relying on memory.

These findings not only deepen our understanding of how the brain works, but also may provide a blueprint for building smarter, more resilient technologies, the research team says.

They detailed their findings Jan. 16 in the Proceedings of the National Academy of Sciences.

A major trial in frontotemporal dementia patients has found that oxytocin can help improve symptoms of apathy. A new study led by Western researchers suggests that frequent treatment with intranasal oxytocin—a hormone linked to empathy—may help reduce apathy in patients with frontotemporal dementia (FTD).
