Researchers discovered the serotonin 2C receptor in the brain plays a crucial role in regulating memory in both humans and animal models. This breakthrough offers insights into conditions associated with memory loss, such as Alzheimer’s disease, and suggests new treatment pathways.
Researchers identified unique molecular signatures of blood-brain barrier dysfunction in Alzheimer’s disease. They discovered altered communication between brain vascular cells mediated by VEGFA and SMAD3 molecules. These findings could lead to new diagnostic biomarkers and treatment options for Alzheimer’s.
Researchers developed a novel peptide, KS-133, to target cognitive dysfunction in schizophrenia. By using a brain-targeting peptide, KS-487, they successfully transported KS-133 across the blood-brain barrier. Their nanoparticle-based drug delivery system improved cognitive functions in mice, offering a new therapeutic strategy.
A new study shows GLP-1 receptor agonists increase pre-meal fullness by activating neurons in the dorsomedial hypothalamus. This mechanism helps prevent overeating, offering insights into obesity treatment. The research highlights how GLP-1 impacts food perception and hypothalamic responses to food cues, enhancing satiation before food intake.
New research shows people are more likely to accuse others of lying when AI makes the accusation first. This insight highlights the potential social impact of AI in lie detection and suggests caution for policymakers. The study found AI’s presence increased accusation rates and influenced behavior, despite people’s general reluctance to use AI lie detection […]
A new study documents the first case of Down syndrome in a Neandertal child named “Tina,” found in Spain. Despite severe hearing loss and vertigo, Tina survived to at least 6 years old, indicating she received extensive care from her group. This discovery highlights the Neandertals’ capacity for altruistic behavior.
esearchers have developed an AI system that guides robots using language-based instructions, improving navigation tasks without relying on extensive visual data. This method converts visual observations into text captions, allowing a language model to direct the robot’s movements. While not outperforming vision-based systems, it excels in data-limited scenarios and combines well with visual inputs for […]
A new study details how AI and computer simulations train robotic exoskeletons to help users conserve energy while walking, running, and climbing stairs. This method eliminates the need for lengthy human-involved experiments and can be applied to various assistive devices.

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.
