Researchers discovered a druggable target that could prevent autonomic dysfunction after spinal cord injury. The research found that microglia cells control abnormal nerve growth and autonomic reflexes. By depleting microglia in a mouse model, researchers prevented life-threatening complications. This finding could lead to new therapies for spinal cord injuries and other neurological conditions.
Incorporating tactile emoticons into social media interactions enhances feelings of support and approval. Participants using a mock platform preferred receiving feedback through both visual and tactile cues over visual-only feedback. Tactile feedback, such as a stroke on the forearm, conveyed additional emotional context. The findings suggest touch can improve digital communication, informing future technology developments.
Researchers successfully used a custom-built robot to treat wet age-related macular degeneration (AMD). This minimally invasive treatment reduces the need for frequent eye injections. The landmark study found that robotic radiotherapy significantly decreases the number of injections needed, potentially saving millions annually. The new method offers precise targeting of radiation to the eye, improving patient outcomes and reducing costs.

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

Eli Lilly’s Alzheimer’s drug, Donanemab, has been recommended for FDA approval by an independent panel. The drug has shown promise in slowing early-stage Alzheimer’s, despite risks like brain swelling. This recommendation follows a prior FDA rejection due to insufficient data. If approved, Donanemab could revolutionize Alzheimer's treatment, offering new hope for patients and their families.
The protein Kif2a acts as a "gardener" for sensory neurons, regulating their axon growth. This pruning process is crucial for managing pain sensitivity. The absence of Kif2a in genetically engineered mice resulted in increased axon density and heightened pain sensitivity over time. However, a compensatory mechanism reduces pain sensitivity in the long term, offering potential insights for chronic pain management.
Poor olfaction in older adults may predict the development of heart failure. The study followed 2,537 participants and found that those with a reduced sense of smell had a 30% higher risk of developing congestive heart failure. This finding suggests a need to further explore the relationship between sensory deficits and heart health. Understanding this link could lead to better early interventions for at-risk populations.

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 created a virtual rat with an AI brain to study how real rats control movement. Using data from real rats, they trained the AI to mimic behaviors in a physics simulator. The virtual rat's neural activations closely matched those of real rats, offering new insights into brain function. This innovation could revolutionize neuroscience and improve robotic control systems.
Wild African elephants use name-like calls to address each other, a rare ability among nonhuman animals. Researchers confirmed this by using machine learning to analyze elephant calls and observing that elephants responded specifically to calls addressed to them.

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

3-year-olds who responded positively to parental praise had fewer behavioral and emotional issues by age 5-7. Children whose behaviors were less influenced by their mood also showed fewer problems. The research, involving 60 children, used toothbrushing videos to measure child behavior and parental praise. This study highlights the importance of early positive reinforcement in child development.
Individuals who physically feel others' pain, known as mirror-pain synaesthetes, are more likely to help. Using fMRI, they observed that these individuals activate their secondary somatosensory cortex more, linking empathy to prosocial behavior. This study highlights the importance of empathy in motivating generosity and offers insights into enhancing prosocial behavior. Findings could inform future interventions to boost empathy.
A new study explores the impact of the internet on human morality, highlighting how evolved responses like compassion and the urge to punish are distorted online. The internet's constant stream of extreme stimuli leads to compassion fatigue, public shaming, and virtue signaling.

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.
Fruit flies use the neurotransmitter octopamine to decide whether food memories are stored long-term or short-term. This process, influenced by energy reserves, affects future eating behavior. High glycogen levels result in stable food memories, prompting increased food intake even after fasting. The research suggests that similar mechanisms may influence overeating in humans.
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.
