Is the physical universe independent from us, or is it created by our minds, as suggested by scientist Robert Lanza?

Gene Changes Linked to Severe Repetitive Behaviors
Summary: Study identifies genes that become activated in the brain prior to the initiation of severe repetitive behaviors associated with addiction, ASD, and schizophrenia.
Source: MIT
Extreme repetitive behaviors such as hand-flapping, body-rocking, skin-picking, and sniffing are common to a number of brain disorders including autism, schizophrenia, Huntington’s disease, and drug addiction. These behaviors, termed stereotypies, are also apparent in animal models of drug addiction and autism.
Gigadalton-scale DNA origami nanostructures explained
Check out this short educational video in which I explain some super exciting research in the area of nanotechnology: gigadalton-scale DNA origami! I specifically discuss a journal article by Wagenbauer et al. titled “Gigadalton-scale shape-programmable DNA assemblies”.
Here, I explain an exciting nanotechnology paper “Gigadalton-scale shape-programmable DNA assemblies” (https://doi.org/10.1038/nature24651).
Though I am not involved in this research myself, I have worked in adjacent areas such as synthetic biology, nanotechnology-based tools for neuroscience, and gene therapy. I am endlessly fascinated by DNA origami and would love to use it in my own research at some point in the future.
I am a PhD candidate at Washington University in St. Louis and the CTO of the startup company Conduit Computing. I am also a published science fiction writer and a futurist. To learn more about me, check out my website: https://logancollinsblog.com/.
Two Halves of the Hippocampus Have Different Gene Activity
Summary: Researchers have identified significant differences in gene activity between the anterior and posterior areas of the hippocampus. Genes associated with depression and other mood disorders are more active in the anterior hippocampus, while genes linked to cognitive disorders, such as ASD, are more active in the posterior hippocampus.

A study of gene activity in the brain’s hippocampus, led by UT Southwestern researchers, has identified marked differences between the region’s anterior and posterior portions.

‘Amazing Natural Experiment’: In This Amazonian Tribe, Brains Don’t Age Like Ours
The Tsimane, an indigenous people who live in the Bolivian peripheries of the Amazon rainforest, lead lives that are very different to ours. They seem to be much healthier for it.
This tribal and largely isolated population of forager-horticulturalists still lives today by traditional ways of farming, hunting, gathering, and fishing – continuing the practices of their ancestors, established in a time long before industrialization and urbanization transformed most of the world.
For the Tsimane, the advantages are considerable. A study published in 2017 found that they effectively have the healthiest hearts in the world, with the lowest reported levels of coronary artery disease of any population ever recorded.
