DNA as a perfect quantum computer based on the quantum physics principles
I believe that dna will be able to answer just about all our genetic coding questions so much that it will lead to even better breakthroughs in the future and use hardly any energy. I believe also that the master algorithm can eventually be derived from DNA as dna seems already a perfect master algorithm for human beings where human beings are the key to all future progress. I say this as quantum computing is still not stable but we already know that dna computers seem already a masterpiece already especially even organoids of the human brain. Really it becomes really quite simple as even the quantum realm is unstable but dna computers that are quantum would stabilize this currently unstable realm.

Researchers discover link between key protein and brain synapse development
Scientists have uncovered how a protein helps build and maintain vital brain connections, providing insights into the neurological problems experienced by people with a rare form of muscular dystrophy known as dystroglycanopathy.
The research conducted at Oregon Health & Science University and published in Communications Biology reveals that the protein Dystroglycan plays a critical role in forming and maintaining connections between nerve cells in the cerebellum—the part of the brain responsible for movement coordination and motor learning.
In people with dystroglycanopathy, genetic mutations in the protein affect not only muscles but also the brain. The condition is a type of congenital muscular dystrophy, a group of inherited disorders that appear at birth or in early infancy.

Blood stem cell mutations linked to lower risk of late-onset Alzheimer’s disease
A study published in Cell Stem Cell reveals that some mutations in blood stem cells might help protect against late-onset Alzheimer’s disease.
A team led by researchers at Baylor College of Medicine discovered that both a mouse model and people carrying blood stem cells with mutations in the gene TET2, but not in the gene DNMT3A, had a lower risk of developing Alzheimer’s disease. Their study proposes a mechanism that can protect against the disease and opens new avenues for potential strategies to control the emergence and progression of this devastating condition.
“Our lab has long been studying blood stem cells, also called hematopoietic stem cells,” said lead author Dr. Katherine King, professor of pediatrics— infectious diseases and a member of the Center for Cell and Gene Therapy and the Dan L Duncan Comprehensive Cancer Center at Baylor. She is also part of Texas Children’s Hospital.
Ultrafast 12-minute MRI maps brain chemistry to spot disease before symptoms
Illinois engineers fused ultrafast imaging with smart algorithms to peek at living brain chemistry, turning routine MRIs into metabolic microscopes. The system distinguishes healthy regions, grades tumors, and forecasts MS flare-ups long before structural MRI can. Precision-medicine neurology just moved closer to reality.
Proteins important in brain communication have different roles than previously thought
Cellular communication between neurons within our brain is complex and busy, much like a USPS mailroom.
To keep things running smoothly, the brain uses specialized molecules, termed alpha-2-delta (α2δ) proteins, to coordinate the sending and receival of signals between nerve cells in the brain.
Genetic variations in these types of proteins can impact important brain messaging and function, resulting in chronic pain, autism spectrum disorders, epilepsy, migraines, and other conditions.
