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.

Researchers identified a new mutation in the ARPP21 gene linked to ALS. The mutation was found in 10 ALS patients from 7 unrelated families in La Rioja, Spain. This discovery could improve ALS diagnosis and open avenues for personalized therapies. The findings emphasize the importance of genetic research in understanding and treating neurodegenerative diseases.
Researchers developed a new approach to improve uncertainty estimates in machine-learning models, enhancing prediction accuracy. Their method, IF-COMP, uses the minimum description length principle to provide more reliable confidence measures for AI decisions, crucial in high-stakes settings like healthcare.
A new study reveals how brain inflammation from infections and neurodegenerative diseases causes muscle weakness by releasing the IL-6 protein. Researchers found that IL-6 travels from the brain to muscles, reducing their energy production and function. This discovery could lead to treatments for muscle wasting in diseases like Alzheimer's and long COVID. Blocking the IL-6 pathway may prevent muscle weakness associated with brain inflammation.

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

A new study finds that semaglutide, known as Ozempic/Wegovy, does not negatively impact brain health and may reduce cognitive problems and nicotine dependence. The analysis, using over 100 million patient records, revealed no increased risk of neurological or psychiatric conditions compared to other antidiabetic medications. These findings suggest semaglutide's benefits may extend beyond diabetes management. Further research is needed to confirm these potential benefits.
A new study predicts cognitive decline rates in people with early Alzheimer's and explores how new drugs may slow this process. Researchers found that prediction models can estimate the rate of decline but with some uncertainty. These models could eventually help answer practical questions about quality of life for patients. The findings highlight the potential of new treatments to delay cognitive impairment.

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 shows that AI helps make stories more creative, engaging, and well-written, especially for less creative writers. The research found that AI assistance boosts novelty and usefulness, making stories more enjoyable and less boring. However, it also warns that widespread use of AI may reduce the diversity and uniqueness of creative works. The findings highlight both the potential and risks of using AI in creative writing.
A new methodology developed by an international research team uses motion capture and the EMOKINE software to decode emotions from movements. The team recorded a dancer performing choreographies expressing various emotions and analyzed the kinematic features of her movements.
A novel AI-powered study explores evolutionary differences between male and female birdwing butterflies, shedding new light on a historic debate between Charles Darwin and Alfred Russel Wallace. Using machine learning to analyze over 16,000 butterfly specimens, researchers found that both sexes contribute to species diversity.

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

A study reveals that narcissism decreases from childhood to older adulthood, though individual differences remain stable over time. People who are more narcissistic as children tend to stay that way as adults.
A new study finds that loneliness impacts memory more negatively than social isolation among older adults. Those who are both socially isolated and lonely experience the greatest memory decline, but loneliness alone also significantly harms memory.

A new study reveals the role of the molecule KIBRA in forming long-term memories. Researchers found that KIBRA acts as a “glue,” binding with the enzyme PKMzeta to strengthen and stabilize synapses, crucial for memory retention. This discovery could lead to new treatments for memory-related conditions. The findings confirm a long-standing hypothesis about memory storage mechanisms.
Researchers discovered a way to increase vitamin B6 levels in cells by inhibiting its degradation, potentially improving memory and learning. Their study found that a natural substance, 7,8-Dihydroxyflavone, inhibits the enzyme pyridoxal phosphatase, enhancing vitamin B6 in nerve cells. This breakthrough could lead to new treatments for mental disorders and neurodegenerative diseases.
A new study uncovers the different patterns and reasons behind procrastination using a mathematical framework. It shows that procrastination is influenced by factors like immediate rewards and uncertainty about future outcomes. These insights can help develop personalized strategies to combat procrastination and improve productivity. The research also highlights the importance of understanding individual procrastination behaviors.

Using machine learning to analyze over 16,000 butterfly specimens, researchers found that both sexes contribute to species diversity.
Researchers have discovered how glial cells can be reprogrammed into neurons through epigenetic modifications, offering hope for treating neurological disorders. This reprogramming involves complex molecular mechanisms, including the transcription factor Neurogenin2 and the newly identified protein YingYang1, which opens chromatin for reprogramming. The study reveals how coordinated epigenome changes drive this process, potentially leading to new therapies for brain injury and neurodegenerative diseases.
