Science news articles cover neuroscience, neurology, psychology, AI, mental health, robotics, neurotechnology and cognitive sciences.

A new study reveals that regular exercise significantly reduces the risk of early death and fatal cardiovascular events more in women than in men, despite women generally engaging in less intense physical activity. Analyzing data from over 400,000 U.S. adults, the research found that women have a 24% lower risk of mortality and a 36% reduced risk of fatal cardiovascular events compared to men's 15% and 14% reductions, respectively.
Cycles of a fasting-mimicking diet (FMD) can effectively reduce signs of immune system aging, insulin resistance, and liver fat, thereby decreasing biological age in humans. The FMD is a five-day plan high in unsaturated fats but low in calories, proteins, and carbohydrates, designed to emulate the effects of water-only fasting while providing essential nutrients.
Researchers made a breakthrough in understanding how the brain makes decisions about future information, pinpointing the lateral habenula as a key player in this process. Their study demonstrates that humans and animals evaluate the worth of cognitive rewards, such as information about the future, using mental rules that the brain applies to both tangible rewards and the intangible satisfaction of curiosity.

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

Smoking not only affects immune responses in the short term but also leaves a lasting imprint on the body's defense mechanisms. Through the Milieu Intérieur cohort of 1,000 healthy volunteers, the study identified smoking, alongside latent cytomegalovirus infection and body mass index, as a key factor influencing immune responses.
A new study reveals epigenetic alterations in the immune system of Alzheimer's patients' blood, suggesting environmental or behavioral factors could influence Alzheimer's risk. The study indicates these epigenetic changes affect genes associated with Alzheimer's susceptibility, potentially due to factors like viral infections or pollutants.
Asian Americans, particularly South and East Asian older adults, exhibit greater hesitancy towards participating in health research involving MRI brain scans compared to their white counterparts. The study surveyed older adults on their perceptions of MRI scans, willingness to learn scan results, and attitudes towards research participation and dementia.

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

Researchers developed an artificial intelligence model that accurately determines the sex of individuals based on brain scans, with over 90% success. This breakthrough supports the theory that significant sex differences in brain organization exist, challenging long-standing controversies.
Researchers developed an innovative AI tool, DeepGO-SE, that excels in predicting the functions of unknown proteins, marking a significant advance in bioinformatics. Leveraging large language models and logical entailment, this tool can deduce molecular functions even for proteins without existing database matches, offering a groundbreaking approach to understanding cellular mechanisms.
Dr. Roman V. Yampolskiy, an AI Safety expert, warns of the unprecedented risks associated with artificial intelligence in his forthcoming book, AI: Unexplainable, Unpredictable, Uncontrollable. Through an extensive review, Yampolskiy reveals a lack of evidence proving AI can be safely controlled, pointing out the potential for AI to cause existential catastrophes.

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

A new study highlights the critical link between sleep, circadian rhythms, and psychiatric disorders, suggesting that disturbances in sleep and internal body clocks can trigger or exacerbate mental health issues. The research underscores the prevalence of sleep-circadian disturbances across all psychiatric disorders, pointing to the need for holistic treatments that address these factors.
Researchers highlighted that around 13% of Norwegian employees are at high risk of burnout. The study introduces a novel tool, the Burnout Assessment Tool (BAT), designed to identify individuals at risk of burnout by measuring exhaustion, mental distancing, cognitive and emotional impairment.
Using antidepressants during pregnancy, specifically fluoxetine (found in Prozac and Sarafem), can significantly affect a child's brain development, particularly in the prefrontal cortex, potentially increasing the risk of mental health disorders later in life. The research highlights how serotonin, boosted by fluoxetine, directly impacts the development of synaptic connections in the prefrontal cortex, a critical area for high-order cognitive functions.

A new study reveals that adolescent girls who ruminate show distinct brain activity patterns when facing social rejection. Using fMRI scans, the research demonstrates increased activity in brain areas related to self-concept and emotional states in girls prone to rumination.
Researchers developed the world's first 3D-printed brain tissue that grows and behaves similarly to natural brain tissue, marking a significant leap forward for neurological and neurodevelopmental disorder research. This novel 3D-printing technique uses a horizontal layering approach and a softer bio-ink, allowing neurons to interconnect and form networks akin to human brain structures.
Researchers achieved a significant advancement in robotics by replicating human-like variable speed walking using a musculoskeletal model. This model, steered by a reflex control method akin to the human nervous system, enhances our understanding of human locomotion and sets new standards for robotic technology.
Researchers have discovered a molecular complex crucial for the transport of mitochondria within neurons, offering new insights into preventing neurodegenerative diseases. The complex, identified as Alex3/Gαq, is pivotal for distributing energy-producing mitochondria throughout neurons, essential for neurotransmission and neuronal functions.
