Viewing images of the same food item multiple times can lead to a feeling of fullness. The study found that when participants viewed the same food picture 30 times, they subsequently chose smaller portion sizes compared to those who saw the image just three times.
Researchers discovered shared genetic underpinnings for cannabis use and psychiatric disorders like schizophrenia and bipolar disorder. Employing advanced statistical modelling, the study revealed a complex interplay of genetic variants increasing or decreasing risk factors for these conditions. These findings may contribute to personalized preventive measures and interventional strategies.
Walking is less popular and more perilous in the U.S. than in other countries, according to a new study. Comparing U.S. statistics to European counterparts like the U.K., Germany, and the Netherlands, the study reveals that Americans take fewer walking trips and face higher fatality rates.
Pregnant women are more likely to complete cannabis use disorder (CUD) treatment if referred by the justice system, community partners, or health care providers. The research provides novel insights into treatment outcomes for pregnant women seeking CUD treatment at public-funding facilities. Findings also showed that only 30% of pregnant women completed treatment, with a 4-to-12-month stay associated with treatment completion.
Researchers discovered an exciting new role for a widely known protein, ubiquitin, particularly in its K-63 form. They found K-63 ubiquitin selectively influences fear memory formation in female brains, potentially contributing to post-traumatic stress disorder (PTSD). This discovery sheds light on why women are more likely to suffer from PTSD and paves the way for developing female-specific therapeutic treatments.
Researchers have identified a potential marker in the brain that might indicate an increased risk of suicide. They observed that veterans with a history of suicide attempts demonstrated distinct functional connectivity between cognitive control and self-referential thought processing networks.
Researchers discovered that through temporary increases in brain malleability and simultaneous desensitization to fear memories, they could control fear responses in mice. This was achieved by inhibiting the Acan gene, thereby decreasing the presence of the protein Aggrecan, which solidifies and reduces malleability in the brain. The findings point towards potential new avenues for the treatment of post-traumatic stress disorder (PTSD).
A new study, based on 36 years of data from nearly 200 baboons, indicates that strong social bonds formed in adulthood can counteract the negative effects of adversity experienced early in life. These hardships, similar to human experiences of growing up in a tumultuous environment, can shorten their lifespan.
