Autism and decision-making – filtering out irrelevant information

Study: Participants who reported autism were less likely to learn from irrelevant information

  • No comments
In a reinforcement learning experiment, participants who reported a diagnosis of autism were less likely to attribute success to details that did not influence it. The researchers suggest that under certain conditions, the ability to ignore "noise" may confer an advantage in receiving

Bar-Ilan University researchers have shown that the protein TMED9 connects two key pathways in the cell's response to stress. In patient-derived DIPG cultures, TMED9 depletion reduced the number of viable cells, their ability to renew themselves, and their ability to

Increased expression of the protein changed chromatin accessibility in the liver of 24-month-old male mice within a month and returned gene activity patterns to a more youthful direction; there is still no evidence that this is a treatment for young people.

Focusing on the sensation of irritation reduced acute dermatitis in a controlled trial

In three pre-registered experiments, Bar-Ilan University researchers found that directing attention to itching and burning after exposure to histamine was associated with a smaller and shorter local inflammatory response; the finding is not evidence for the treatment of chronic inflammation.

Small RNA molecule modifies the ribosome and helps the Leishmania parasite adapt to its host

A study jointly led by researchers from Bar-Ilan University and the Weizmann Institute of Science found that a certain snoRNA affects both a chemical change in ribosomal RNA and ribosome folding, thereby altering the translation patterns of
Incompressible encryption may protect information even after the key is leaked

Incompressible encryption may protect information even after the key is leaked

A method developed by researchers at Bar-Ilan University turns storing the encryption formula itself into a valuable resource; even if the key is revealed in the future, an attacker who did not store enough information in advance will not be able to reconstruct the message.

How fulfilling a violated need can open a path to reconciliation

The research of Dr. Ma'an Katzir from Bar-Ilan University examines how psychological needs that are affected by conflict translate into emotions such as anger and fear - and how meeting a need, even from a third party, may reduce negative emotions and increase
The illustration shows the **Enh13** control region alongside the **Sox9** gene as a sort of “battlefield” between the two sex development pathways. Factors that promote female development act to repress **Sox9** by binding to **Enh13**, while factors that promote male development activate it. It is the balance between these opposing forces that ultimately determines whether male or female development occurs. Credit: Neta Varsano.

Tiny change in DNA caused female mice to develop in a male pathway

Researchers from Bar-Ilan University have shown that a single letter change in a non-protein-coding control region can activate the Sox9 gene and alter the course of sexual development in mice. The study highlights the importance of

When the virus leaves a mark: Epigenetic “stamp” after hepatitis C cure may explain ongoing risk of liver cancer

  • One response
Research led by Prof. Meital Gal-Tanaami of Bar-Ilan University and supported by the Israel Science Foundation is examining how a virus that remains in the cytoplasm manages to change genetic control in the nucleus, and is attempting to map points of intervention to reduce cancer risk as well.
