Human services are collapsing: can artificial intelligence be the lifeline?

  • No comments
Any public service of human help, such as mental health care or care for the elderly collapses. The artificial intelligence that will take over many jobs will leave us with the thing that is perhaps most important to us, the value we find in human effort for the sake of others.

Breakthrough in Alzheimer's research among women

  • No comments
Professor Hermona Sorek, one of the world's leading researchers of gene expression in the brain, was able to find, in collaboration with her research colleagues, a molecular mechanism that occurs in the brains of Alzheimer's patients, which does not occur in men and which explains the acceleration of cognitive deterioration in Alzheimer's patients

Researchers at the Hebrew University and the University of Kentucky believe that a specific type of protein, which has not been studied before, substantially increases the molecular complexity in the brain and improves its function. "Such a discovery may have implications for the study of neurological diseases such as schizophrenia, epilepsy and autism"

Prof. Schwartz challenged the convention that nerve cells do not regenerate or recover, and discovered that the immune system also takes care of them. She also studied the blood-brain barrier and discovered that it prevents the cells of the immune system from helping in cases of brain damage such as Alzheimer's

  • One response
An international research group led by scientists from Ben-Gurion University of the Negev discovered among a species of crabs a mechanism that produces a unique eye shine that reflects light in a color adapted to the color of the water in their natural environment and thus enables camouflage in different habitats. The research findings were published in the journal Science

Researchers from Tel Aviv University mapped risk factors for the complex eye disease AMD in the genome

As part of the study, the Ashona researchers were able to identify proteins whose role is essential for the development and activity of the tissue affected by the disease, to precisely locate their location in genomic regions outside of the genes, and to identify the relationship between the changes in these regions and the risk of developing AMD
