Common HIV drugs could reduce the incidence of Alzheimer’s disease (AD). Utilizing anonymized prescription data from over 225,000 individuals, the study found that HIV-positive patients taking reverse transcriptase (RT) inhibitors showed a significantly lower rate of AD compared to the general population.
Researchers made significant progress in understanding color perception by identifying non-cardinal retinal ganglion cells (RGCs) in the human fovea. These cells may explain complex color perceptions beyond the traditional models established by the cardinal directions of color detection.

Neurology news articles cover neurology, brain cancer, traumatic brain injuries, neurosurgery, neuroanatomy, brain research and neurological disorders.

Prasinezumab, a monoclonal antibody targeting alpha-synuclein aggregation, shows promise in slowing motor deterioration in rapidly progressing Parkinson's disease (PD), according to an exploratory analysis from the phase 2 PASADENA clinical trial. While there are currently no disease-modifying treatments for PD, prasinezumab offers a potential breakthrough by specifically binding to aggregated alpha-synuclein, a key driver of PD pathology.
People with Parkinson’s disease experience altered bodily sensations related to basic emotions differently from healthy individuals. Utilizing electronic body maps, participants identified how emotions like anger, happiness, and sadness manifested physically, noting significant shifts in sensation locations, particularly with anger moving from the chest to the abdomen.
Deep brain stimulation (DBS) in the subthalamic nucleus, a treatment for Parkinson's disease, may influence more than just motor control. This treatment, which mitigates Parkinson's symptoms such as tremors, also appears to affect patients' ability to shift their attention between tasks.

AI news articles cover science articles about artificial intelligence including ChatGPT, Bard, Dalle, neural networks, machine learning, LLMs, AGI and other AI related topics.

A new study investigates the role of social media in exacerbating eating disorders among users. Researchers used machine learning to analyze millions of tweets, uncovering a troubling cycle where harmful content related to eating disorders is easily accessible and often intertwined with regular diet discussions.
Researchers developed a new machine learning technique to improve red-teaming, a process used to test AI models for safety by identifying prompts that trigger toxic responses. By employing a curiosity-driven exploration method, their approach encourages a red-team model to generate diverse and novel prompts that reveal potential weaknesses in AI systems.

Science research articles cover psychology, depression, mental health, schizophrenia, mental disorders, happiness, stress, PTSD, autism, psychiatry and therapy.

Researchers shed light on how human brains handle decisions that impact others, particularly when options conflict. In their study, participants engaged in tasks designed to assess their preference integration and decision-making processes for both personal and others' benefits.
Physical activity significantly reduces the risk of cardiovascular disease by diminishing stress-related brain signaling. The study, which analyzed data from over 50,000 participants, showed that individuals who adhered to physical activity guidelines had a 23% lower risk of developing heart disease.

Adolescents engaging in "transcendent thinking"—the practice of looking beyond the immediate context to understand deeper meanings and implications—can significantly influence their brain development. The study highlights how this complex form of thinking fosters coordination between the brain's executive control and default mode networks, crucial for psychological functioning.
Researchers uncover the nuanced mating behaviors of nematodes, revealing a complex interplay between hermaphroditic and female roundworms in their quest for reproduction. While females actively seek out males, tracking them by smell for mating, hermaphrodites exhibit a starkly different approach, avoiding mating until they deplete their sperm supply. This research not only enhances our understanding of nematode reproductive strategies but also offers insights into the genetic mechanisms of attraction and behavioral evolution. semination.
New research highlights a significant loneliness gap between middle-aged adults in the U.S. and their European counterparts, with Americans experiencing higher levels. The study utilized data from over 53,000 participants to explore loneliness trends across three generations, finding that U.S. adults report increasing loneliness, particularly among younger generations.
Researchers unveiled a groundbreaking discovery that DNA damage and brain inflammation are vital processes for forming long-term memories, particularly within the brain's hippocampus. Contrary to previous beliefs associating inflammation with neurological diseases, this study highlights inflammation's critical role in memory formation through the activation of the Toll-Like Receptor 9 (TLR9) pathway following DNA damage in hippocampal neurons.
A new study utilizing UK Biobank data has unveiled the genetic roots of left-handedness, pinpointing rare variants in the beta-tubulin gene TUBB4B significantly associated with this trait. These findings not only shed light on the complex interplay between genetics and brain asymmetry but also link left-handedness with neurodevelopmental disorders through shared genetic pathways.
