A new experimental cancer drug could ease cognitive difficulties for those with Rett syndrome, a rare autism-linked disorder, by enhancing brain cell functions. The drug, ADH-503, improves the activity of microglia, which are crucial for maintaining neural networks ..read more

A new study proposes a novel approach to studying consciousness through behavioral observations and learning curves. The study highlights that learning often occurs in sudden leaps, suggesting these "eureka moments" are preceded by conscious cognitive processes ..read more

Researchers uncover how specific brain cells and circuits become vulnerable in Alzheimer's disease and identify factors that may promote resilience to cognitive decline. Analyzing gene expression in over 1.3 million cells across multiple brain regions, the study highlights the role of Reelin in neuron protection and choline metabolism in astrocytes for cognitive resilience. These findings pave the way for potential therapeutic targets to sustain cognition and memory amid Alzheimer’s pathology ..read more

A new study reveals that chronic and new anxiety are linked to a higher risk of dementia, while resolved anxiety shows no such association. Following 2,132 Australian individuals for 10 years, researchers found that chronic and new anxiety increased dementia risk by 2.8 and 3.2 times, respectively. Those whose anxiety began before age 70 faced even greater risks. The findings suggest that addressing anxiety could help prevent dementia ..read more

Research reveals that increased alcohol consumption in individuals with bipolar disorder can exacerbate their symptoms over time. Contrary to the belief that alcohol acts as self-medication, the study shows no increase in drinking due to heightened mood symptoms ..read more

Researchers used Game of Thrones to study how the brain recognizes faces, providing insights into prosopagnosia, a condition affecting facial recognition in 1 in 50 people. MRI scans showed increased brain activity in regions associated with character knowledge in fans of the series, but reduced activity in those unfamiliar with the show and in prosopagnosia patients ..read more

Individuals with the 22q11.2DS genetic deletion show unique patterns of brain activity and structure, which could predict their risk of psychosis. By studying brain "coupling" from childhood to adulthood, scientists discovered discrepancies in brain regions linked to schizophrenia ..read more

Researchers have found that chimpanzees communicate with gestures in a rapid turn-taking pattern similar to human conversation. Studying over 8,500 gestures across five wild communities, they discovered that chimpanzees exchange gestures with pauses averaging 120 milliseconds ..read more

Exercising our brains with daily habits like naps and memory workouts, instead of relying on smartphones, can reduce the risk of age-related dementia. A new study highlights the superiority of human intelligence over AI. The study emphasizes nurturing our brain's potential for healthy aging. It also offers practical tips for boosting brain power and maintaining real intelligence ..read more

Summary: New research finds that dogs exposed to human stress odors make more ‘pessimistic’ choices, indicating a negative emotional state. The study shows how human stress affects dogs’ learning and perception of rewards. This understanding can improve the wellbeing of dogs in kennels and enhance training for companion and working dogs. These findings highlight the deep connection between human emotions and canine responses. Key Facts: Source: University of Bristol Dogs experience emotional contagion from the smell of human stress, leading ..read more
