New research following children for more than a decade links high screen exposure before age two to accelerated brain maturation, slower decision-making, and increased anxiety by adolescence. Infants with more screen time showed premature specialization in brain networks involved in visual processing and cognitive control, which later reduced flexibility during thinking tasks.
Autistic adults show reduced availability of a key glutamate receptor, mGlu5, across widespread brain regions. This difference supports the theory that an imbalance between excitatory and inhibitory signaling may contribute to autism-related traits.
High levels of the periodontal bacterium Fusobacterium nucleatum may be associated with more severe disability in people with multiple sclerosis. Researchers analyzed tongue-coating samples and found that MS patients with the highest abundance of this bacteria had significantly worse scores on a standard disability scale.
A new study comparing stroke survivors with healthy adults reveals that post-stroke language disorders stem not from slower hearing but from weaker integration of speech sounds. While patients detected sounds as quickly as controls, their brains processed speech features with far less strength, especially when words were unclear.
When people facing uncertainty about an important identity goal are nudged to question the validity of their own doubts, their commitment to that goal actually increases. The research demonstrates that inducing meta-cognitive doubt—doubt about one’s doubts—can flip ambivalence into renewed motivation.

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

A new study challenges the long-held belief that Alzheimer’s disease cannot be reversed. Researchers showed that a severe drop in NAD+—a core energy molecule—drives Alzheimer’s pathology in both human brains and mouse models.
Chronic circadian disruption — such as night-shift work, irregular schedules, or frequent jet lag — accelerates the development and spread of aggressive breast cancer. Researchers found that disrupted internal clocks not only weaken immune defenses but also reshape healthy breast tissue, creating conditions that tumors exploit.
Social isolation has a direct causal impact on how quickly cognitive function declines in later life, independent of whether someone feels lonely. By analyzing more than 137,000 cognitive tests from over 30,000 older adults, the study found that reduced social contact consistently predicted faster decline across every demographic group.
Breast cancer can rapidly derail the brain’s day-night regulation of stress hormones, even before tumors are detectable. In mice, the disease flattens normal corticosterone rhythms by altering hypothalamic neuron activity, which may worsen outcomes and mimic symptoms often seen in cancer patients, such as insomnia and anxiety.

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 biologically grounded computational model built to mimic real neural circuits, not trained on animal data, learned a visual categorization task just as actual lab animals do, matching their accuracy, variability, and underlying neural rhythms. By integrating fine-scale synaptic rules with large-scale architecture across cortex, striatum, brainstem, and acetylcholine-modulated systems, the model reproduced hallmark patterns of learning, including strengthened beta-band synchrony between regions during correct decisions.
A new theoretical framework argues that the long-standing split between computational functionalism and biological naturalism misses how real brains actually compute. The authors propose “biological computationalism,” the idea that neural computation is inseparable from the brain’s physical, hybrid, and energy-constrained dynamics rather than an abstract algorithm running on hardware. In this view, discrete neural events and continuous physical processes form a tightly coupled system that cannot be reduced to symbolic information processing.
Researchers have developed an AI-driven brain model that can track fear as it unfolds in real-world situations, offering a major shift from traditional lab-based approaches. Classic fear studies often rely on static images, but these do not reflect how the brain processes fear in dynamic contexts.
New research shows that deep learning can use EEG signals to distinguish Alzheimer’s disease from frontotemporal dementia with high accuracy. By analyzing both the timing and frequency of brain activity, the model uncovered distinct patterns: broader disruption across multiple regions in Alzheimer’s and more localized frontal and temporal changes in frontotemporal dementia.
A new study shows that integrating artificial intelligence with advanced proximity and pressure sensors allows a commercial bionic hand to grasp objects in a natural, intuitive way—reducing cognitive effort for amputees. By training an artificial neural network on grasping postures, each finger could independently “see” objects and automatically move into the correct position, improving grip security and precision.

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

People instinctively mimic others’ facial expressions, but new research shows we do this far more with joyful faces than with sadness or anger—and that the intensity of mimicry predicts how much we trust someone. Across three experiments using EMG and behavioral tasks, participants copied smiles more readily and rated smiling individuals as more attractive, confident, and trustworthy.
uilt and shame arise from different cognitive triggers and rely on distinct neural systems to guide compensatory behavior. Using a controlled game that manipulated both harm and responsibility, researchers showed that guilt is more strongly driven by the severity of harm caused, while shame is more strongly shaped by how responsible someone feels for that harm. Guilt also more reliably translated into financial compensation, whereas shame required greater cognitive control to influence behavior.
Depression and anxiety may heighten cardiovascular disease risk through chronic stress pathways in the brain and body. In a large analysis of more than 85,000 adults, those with depression or anxiety — especially both — were significantly more likely to experience heart attack, stroke or heart failure.
New research shows that buying second-hand gifts is typically a thoughtful, intentional decision rather than an impulsive one. Consumers are motivated by fair prices, the thrill of finding rare items, and the desire to shop sustainably. Survey results from a major online marketplace reveal that intentions often translate directly into purchases—especially for items that are easy to evaluate, such as books.

A new study proposes that autism arises when genetic vulnerability, an early environmental trigger, and prolonged activation of the cellular stress response align during critical developmental windows. This “three-hit” metabolic model reframes autism as a disorder of disrupted cellular communication and energy metabolism rather than an inevitable genetic outcome.
New work explores why consciousness evolved and what observing birds can teach us about its biological purpose. The findings outline three distinct forms of consciousness—basic arousal, general alertness, and reflexive self-awareness—each providing unique adaptive advantages.
Researchers have made a major advance, discovering that a low-dose mixture of zinc, serine, and branch-chain amino acids (BCAAs) can successfully alleviate behavioral symptoms in three different mouse models of autism. This breakthrough lies in the synergy of the three common nutrients, which work together to restore normal neural communication and reduce hyperactivity in the brain's emotional center.
A new study shows that precisely manipulating brain activity during sleep can help mice retain memories that would normally fade, offering a potential pathway for treating memory loss conditions. Researchers identified a specific sleep-related pattern—large sharp-wave ripples—that signals when new experiences are being transferred from the hippocampus to the neocortex for long-term storage. By boosting these ripples at just the right moment using optogenetics, scientists enabled mice to remember brief encounters they would typically forget.
