Neuroscience News Home

Neuroscience News is an independent open access science magazine. Since 2001, we have featured neuroscience research news from labs, universities, hospitals and news departments around the world. Topics include brain research, AI, psychology, neuroscience, mental health and neurotech.

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

Mild dehydration can impair sustained attention in middle-aged and older adults, though it doesn't affect other cognitive functions. The study involved 78 adults, ages 47 to 70, and assessed their hydration levels and cognitive performance. Results showed that dehydration, common during typical daily activities, reduced attention span over 14 minutes. The findings highlight the need for regular hydration to maintain cognitive function in older adults.

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

A new study finds a link between a diet high in ultra-processed foods and an increased risk of cognitive impairment and stroke. This association was particularly pronounced among Black participants. While more research is needed, the findings highlight the potential impact of food processing on brain health.
A new study finds that urolithin A, a substance found in pomegranates, can improve memory and may help treat Alzheimer's disease. This natural compound works by removing damaged mitochondria from the brain, similar to the effects of NAD supplements. While dosage is still being determined, this discovery offers promising potential for treating and preventing neurodegenerative diseases.
A new study reveals a significant link between hot nights and increased stroke risk, particularly in the elderly and women. Researchers analyzed 15 years of data from Augsburg University Hospital and found a 7% increased risk of stroke following tropical nights.

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 AI model of the fruit fly brain to understand how vision guides behavior. By genetically silencing specific visual neurons and observing changes in behavior, they trained the AI to predict neural activity and behavior accurately. Their findings reveal that multiple neuron combinations, rather than single types, process visual data in a complex "population code." This breakthrough paves the way for future research into the human visual system and related disorders.
Researchers developed DEPLOY, an AI tool that can classify brain tumors into 10 major subtypes with 95% accuracy. The tool analyzes microscopic images of tumor tissue, providing a faster and more accessible alternative to DNA methylation-based profiling. DEPLOY could potentially be used to classify other cancers as well.

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

A new study finds that children not deemed "school ready" at age 4 are significantly more likely to be unemployed or out of education by 16. This early disadvantage also predicts lower GCSE achievement. Researchers used data from over 8,000 Bradford young people to identify this link. This highlights the need for early intervention in schools to reduce later disadvantage.
A new study finds a strong association between teen cannabis use and a significantly increased risk of developing psychotic disorders. This risk appears to be age-dependent, with adolescents being particularly vulnerable to the effects of cannabis on their developing brains. While further research is needed, these findings raise concerns about early cannabis use and highlight the importance of prevention strategies.
A new study reveals that ancient viral DNA sequences, once thought to be "junk DNA," are active in the human brain and contribute to the risk of psychiatric disorders like schizophrenia, bipolar disorder, and depression. This discovery sheds light on the complex genetic factors influencing mental health.

Researchers found that a hormone-producing cell in the adrenal glands may explain why oldfield mice are monogamous while their close relatives are promiscuous. This hormone, 20⍺-OHP, boosts nurturing behavior, suggesting a link to monogamy.
Researchers explore the intricate mechanisms of memory and debunk common myths about its function. They argue that memory is not a static recording but a dynamic, editable process akin to a Wiki page, and emphasize that forgetting is a normal part of how our brains prioritize information.
A new study finds that altered states of consciousness (ASCs), like those experienced during meditation, are more common than previously thought. 45% of respondents reported experiencing ASCs at least once, often leading to positive outcomes. However, a significant minority also reported negative or even life-threatening suffering, highlighting the need for better support and understanding of these experiences.
