tRNA Fragments Linked to Alzheimer’s

A new study identifies a crucial factor in brain aging and Alzheimer's disease—the accumulation of Glu-5’tsRNA-CTC in neuron mitochondria. This small RNA fragment disrupts mitochondrial protein synthesis and cristae structure, accelerating cognitive decline and Alzheimer’s pathology.

Does Revenge Taste Sweet? New Study Challenges Assumptions

A new study explores the complex moral landscape of revenge, revealing that people's reactions to revenge vary significantly based on the emotions displayed by the avenger. Conducted across four surveys involving Polish students and American adults, the study found that avengers who demonstrate satisfaction are viewed as more competent, whereas those expressing pleasure are seen as immoral.

Naming Scents: How Labels Shape Our Perception of Odors

New research reveals that the names we assign to odors can significantly influence how we perceive them. In a study utilizing ultrahigh-field functional MRI technology, participants rated identical odors as more dissimilar when they were given different names, underscoring the impact of language on sensory experience. The study tracked how odor information is processed in the brain's primary olfactory cortex, specifically the piriform cortex, and showed different brain activities based on the labels used.

Neurology News Articles

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

Sleep May Not Aid Brain Detox

A new study challenges the prevailing theory that sleep aids in the detoxification of the brain. Researchers found that the brain's toxin clearance is significantly reduced during sleep and even more so under anesthesia, as shown by the slower movement and clearance of a fluorescent dye in the brains of mice.

Wrap Around Spinal Cord Device May Transform Injury Treatment

Researchers developed a groundbreaking electronic device that wraps around the spinal cord, offering a new method for treating spinal injuries without the need for brain surgery. This device can record and stimulate nerve signals across the entire spinal cord, providing a complete 360-degree view of spinal activity.

A New Era in Neuroscience with Generative AI

Researchers developed a groundbreaking model called Brain Language Model (BrainLM) using generative artificial intelligence to map brain activity and its implications for behavior and disease. BrainLM leverages 80,000 scans from 40,000 subjects to create a foundational model that captures the dynamics of brain activity without the need for specific disease-related data.

AI News Articles

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

The Rise of Deceptive AI: Manipulation to Achieve Goals

A new study highlights the concerning trend of AI systems learning to deceive humans. Researchers found that AI systems like Meta's CICERO, developed for games like Diplomacy, often adopt deception as a strategy to excel, despite training intentions.

Visual Diet Shapes Development in Infants

Researchers uncovered a critical aspect of infant vision, revealing that very young babies experience a unique visual diet consisting of simple, high-contrast patterns and edges found in everyday environments. This "diet" significantly influences their developmental trajectory.

New Study Redefines Human Sound Localization

Researchers challenged a longstanding theory from the 1940s about how humans locate sounds, a discovery with profound implications for hearing technology. The study reveals that humans utilize a simpler, more energy-efficient neural network for spatial hearing, similar to other mammals like rhesus monkeys and gerbils.

Psychology News Articles

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

Psilocybin Shows Promise in Anorexia Treatment

A new study highlights the potential of psilocybin, found in magic mushrooms, as a treatment for anorexia nervosa (AN), a psychiatric disorder with one of the highest mortality rates. The research demonstrated that psilocybin enhances cognitive flexibility and body weight maintenance in an animal model of AN.

High-Potency Cannabis Linked to Youth Psychosis

Young individuals who use high-potency cannabis between ages 16 and 18 are twice as likely to experience psychosis by their mid-twenties compared to those who use lower-potency strains. This research utilized data from the Children of the 90s study, tracking thousands of participants from Bristol.

Exercise Warps Time Perception

People perceive time as moving slower when they are exercising compared to resting or post-exercise. The research involved participants undergoing a time perception task during different cycling conditions, including solo and competitive scenarios.

The Secrets to Enhancing Memory for Everyone

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.

Pupil Dilation Linked to Working Memory Capacity

Researchers discovered that pupil dilation can indicate levels of working memory. In a study, researchers observed that individuals whose pupils dilated more while performing memory tasks tended to have better working memory.

Why We Forget: New Insights into Everyday Memory

A new study investigates why everyday actions like locking a door are often forgotten. Researchers explored how people tend to remember significant events rather than routine details.

Brain Cells That Enhance Memory Focus and Storage Identified

Researchers uncovered how certain brain cells enhance our ability to maintain and focus on short-term memories. Their study highlights a new type of neuron, dubbed PAC neurons, which coordinate the activity of memory-specific neurons without storing any information themselves.

Environment Shapes Emotional Cognitive Abilities More Than Genes

Environmental factors may have a more significant impact on certain cognitive abilities than genetics. The study involved 57 pairs of identical and 48 pairs of fraternal twins from the Beijing Twin Study, focusing on metacognition and mentalizing—abilities tied to understanding and controlling one's cognitive processes and recognizing emotions in others, respectively.
