Widely used pesticides may pose a greater threat to brain health than previously realized. UCLA Health researchers report that long-term exposure to chlorpyrifos near the home is associated with a more than 2.5-fold increased risk of developing Parkinson’s disease. This research molecular neurodegenerationcombined evidence from hundreds of people with laboratory experiments designed to reveal exactly how pesticides affect the brain. The results suggest that chlorpyrifos can damage important nerve cells involved in movement and may play a direct role in the development of Parkinson’s disease. Why is Parkinson’s disease important? Parkinson’s disease is a progressive neurological disease that affects approximately…

Astronomers led by Northwestern University have discovered an unusual feature around the famous “pink planet”: a sky filled with salty clouds. The ancient world, known for its pinkish haze, has remained one of astronomy’s enduring mysteries for more than a decade. One of the coldest planetary-mass companions ever imaged directly, the object is so faint that scientists have struggled to analyze the light from Earth. Now, observations from the James Webb Space Telescope (JWST) reveal an atmosphere filled with exotic chemicals and clouds unlike anything seen before. The discovery provides some of the first direct evidence that salt clouds may…

A 12-month longitudinal study of adolescents found that those who had experienced more negative events in their lives tended to have more severe depressive symptoms. This association was particularly pronounced regarding negative self-evaluation. Girls who experienced more negative life events reported greater increases in negative self-evaluation symptoms than boys. The paper is scientific report. Depression is a mental health disorder characterized by persistent feelings of sadness, emptiness, or loss of interest in activities. It affects how a person feels, thinks, acts, and functions in daily life. Common symptoms include low mood, fatigue, difficulty concentrating, trouble sleeping, changes in appetite, and…

Children with Attention Deficit Hyperactivity Disorder, who have a clear divide between verbal and nonverbal intelligence, face significant challenges in self-control and concentration. These mental gaps coincide with reduced blood flow to the front of the brain during tasks that require impulse control. The results were published in the magazine NeuroImage. Attention-deficit hyperactivity disorder is one of the most common neurodevelopmental disorders in school-age children. Its main characteristics include an inability to maintain concentration, physical restlessness, or impulsive behavior. These symptoms often result from weaknesses in executive function. Executive function functions as the brain’s management system, organizing thoughts, regulating emotions,…

As artificial intelligence becomes more commonplace in professional settings, human oversight is often promoted as a safeguard against automated mistakes. New research published in PNAS Nexus Our results suggest that human experts are significantly more likely to mistakenly accept a harsh decision if they believe that the decision was made by an artificial intelligence system rather than a human colleague. This pattern provides evidence that relying on human reviews to spot algorithmic errors may not be as effective as many expect. Study author Rigissa Megalokonomo, associate professor of economics at Monash University, was drawn to this issue by the rapid…

The way people choose potential romantic partners may rely on the same mental decision-making system used for many other types of choices, according to a recent study. The study found that a computational model accurately predicted both who people chose as potential partners and how quickly they made that decision. This research cognitive science. Researchers have been trying to understand what drives romantic attraction for decades. Scientists have learned a lot about what characteristics people like and what characteristics are deal-breakers, but they know less about the mental processes that combine those preferences to make the final decision. The current…

A recent study found that the degree to which a person has autistic traits is related to how their brain processes social rewards compared to non-social rewards. The researchers found that poor connectivity between certain brain regions helps explain why people with more autistic traits often show no behavioral preference for social imagery. These findings show that personality neuroscience. Daily life is full of rewards that shape human behavior. There are also purely physical or material rewards, such as a delicious cake or finding money on the street. Other rewards can be social, such as a warm smile from a…

Recent research published in International Journal of Psychology provide evidence that insecure attachment styles tend to be associated with a larger number of children. This research suggests that cultural norms play an important role in how our deeply ingrained relationship habits influence family size. These findings question the assumption that a secure attachment style is always the most beneficial trait for reproductive success. Attachment theory explains how early interactions with caregivers shape how people relate to others throughout their lives. According to this framework, individuals develop pragmatic models of themselves and others that guide their expectations in romantic partnerships and…

Last week, those trying to squeeze in a productive day’s work in the searing heat of southern England had little doubt about the effects of extreme weather.But the economic impact of the climate crisis in the UK is not limited to the many hours lost in a quiet sweat or getting children out of the scorching classroom early.Two well-timed interventions last week by financial lobby group TheCityUK and Swati Dhingra, an economist and independent member of the Bank of England’s Monetary Policy Committee, drove home that point.Both men pointed to the need for the government to play a more active…
