The cause of aging: cumulative damage from factors such as radiation and smoking causes low expression of long genes

  • No comments
Dutch researchers found that this process happens all the time and damages all genes, but the longer the genes, the more likely they are to be damaged because they have more sites. Especially the great damage is to nerve cells due to their inability to regenerate

This is how the bone marrow reacts to injuries and infections

  • No comments
Dr. Kathryn Vandorna from the Faculty of Biomedical Engineering at the Technion developed a new method that allows the monitoring of the formation of immune blood cells in the bone marrow. For this purpose, she used tiny magnetic particles of iron oxide, which she followed with various imaging methods, including MRI of the living creature

Prof. Haim Sompolinski is the first Israeli researcher to win the prestigious award, he himself was born in Denmark whose father, Prof. David Sompolinski, was among the members of the underground who smuggled the Jews to Sweden by boat
A man implanted with a brain chip and started walking. The image was created by the artificial intelligence software DALEE and is presented as an illustration only and is not a scientific image.

First brain chip that treats epilepsy and OCD at the same time

Implanting a chip in the brain as recently done by Elon Musk's company Neurolink can, if done correctly, save patients with severe brain diseases, and that the patients no longer respond to drug treatment
Reading thoughts before they become words. The figure was prepared using DALEE software after reading the article.

mind reading? Researchers have developed a method that will allow us to know what we are going to say before we speak

  • No comments
Individual neurons could recognize, for example, when we are about to touch our tongue to our palate to say the letter D * This will enable the development of prostheses for those suffering from speech problems
The pituitary gland of the zebrafish. The variety of cell types are marked in different colors: in purple - phytocytes, in red and green - two types of hormone-producing cells

Where does the fish secrete from: back to the origins of the pituitary gland

Weizmann Institute scientists are challenging a 200-year-old doctrine about the formation of the gland from the secretion of hormones. Their findings may lead to new approaches in the treatment of various medical problems

Elon Musk's Neuralnik Implanted a Chip in a Man's Brain: Medical and Ethical Implications

  • No comments
The chip should provide a variety of health and scientific benefits, including the ability to measure brain activity and give people with physical or mental disabilities new abilities. However, Musk's company and Musk in general have a problematic history

The mechanism that dramatically links anxiety and testosterone has been discovered

  • One response
Krim suggests a close link between low levels of testosterone and anxiety disorder, although the exact nature of this relationship remains unclear. Clinical evidence suggests the potential of testosterone in alleviating anxiety and depression, especially in men with low testosterone.

When and why are we ready to give up money?

Researchers have found that fulfilling a stereotype leads to a reward response in the brain and that people are even willing to give up money for it

In the tears you cry: smelling women's tears reduces aggression in men

Scientists at the Weizmann Institute of Science discovered that tears activate human olfactory receptors, even though they are odorless, affecting the brain activity associated with aggression - and leading to more peaceful and less vengeful behavior

The nervous mechanism that goes wrong as a result of exposure to a severe event at a tender age

Weizmann Institute of Science scientists reveal in unprecedented detail how trauma in newborn mice shapes their brains and impairs their social functions in adulthood * A corresponding behavioral expression in humans may take the form of a high level of introversion, social anxiety and avoidant personality - behaviors known to characterize post-trauma"

With a simple blood test it is possible to identify people dealing with bipolar disorder and whether they will respond to lithium treatment

  • No comments
One of the most common treatments for bipolar disorder today is the drug lithium - a drug to which only about a third of patients respond. The research aims to understand what causes this

MRI scans can provide information about the iron balance in the brain to help monitor and diagnose various diseases, in a non-invasive manner

  • One response
This new measurement method, developed by PhD student Shir Filo and Prof. Metzer, will allow the extraction of precise biological values ​​on the brain, so that it will be possible to derive from an MRI test similar indicators to those obtained from a blood test or from a brain biopsy

Read melodies from the brain with Pink Floyed

A new study, published in mid-August in the prestigious journal PLOS Biology, reveals a way to decipher the songs playing inside the brain. In doing so, he also provides an explanation about the way in which different areas of the brain perceive and respond to acoustic elements

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. Michal Schwartz from the Weizmann Institute won the Israel Prize for research on the relationship between the immune system and the nervous system

  • 3 תגובות
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
