Summary: Using a novel brain-computer interface, researchers restored a functional sense of touch to a 28-year-old man with a severe spinal cord injury, significantly improving his hand control and object interaction. Source: Cell Press Researchers aiming to restore limb function for people with paralysis emphasize that touch is more than a convenience—it is essential for … Read more

Quantitative tools reveal how two genes mutated in early-onset Parkinson’s collaborate to flag damaged mitochondria Researchers investigating two genes that are mutated in early-onset Parkinson’s disease have clarified how the normal forms of these genes cooperate to remove damaged mitochondria from cells. Mitochondria provide the cell’s energy and their integrity is essential for neuronal health. … Read more

Summary: Researchers at Tufts University have developed a faster method to produce human neural stem cells that differentiate rapidly, improving options for tissue engineering and three-dimensional brain models. Source: Tufts University New process may enable engineering of innervated tissues such as skin, cornea, and functional human brain models. Scientists at Tufts University report a streamlined … Read more

Newly identified color-vision circuitry in mice offers insight into why the night sky can appear bluish in low light. Discovery connects mouse retinal circuits to the “blue” of twilight For more than a century biologists have puzzled over a simple but striking observation: under very dim light the sky often appears to take on a … Read more

Summary: UCLA researchers report that the amygdala contains far more diverse cell types than previously recognized, and they introduce a method to link specific cell types to behavior. Source: UCLA UCLA researchers have produced the first comprehensive cellular map of the amygdala, a brain region central to emotion and social behavior and implicated in conditions … Read more

“Now-or-Never” Bottleneck: How Memory Limits Shape Language Processing and Learning Summary: Fundamental limitations in sensory and cognitive memory play a central role in how language is processed, learned and evolves, according to new research. Source: Cornell University. How does the brain make sense of the constant stream of speech and sign when sensory memory preserves … Read more

Summary: A large, multiethnic study found that people who drink at least one cup of coffee daily have a lower risk of death from major causes — including heart disease, cancer, stroke, diabetes and respiratory and kidney disease — compared with those who do not drink coffee. The reduced mortality risk was similar for caffeinated … Read more

Summary: A new study reveals that glioblastoma tumors reprogram microglia, the brain’s resident immune cells, causing them to support tumor growth rather than attack it. Source: Karolinska Institute. Glioblastomas influence microglia—the brain’s immune cells—so that these cells promote cancer growth instead of fighting it. An international research team led by investigators at Sweden’s Karolinska Institutet … Read more

Motor Skill Delays in Children with Autism Linked to Greater Social and Communication Challenges New research indicates that children with autism who have delayed motor skills — especially object-control skills like catching and throwing — often face more pronounced social and communication difficulties. The study, published in the July issue of Adapted Physical Activity Quarterly, … Read more

Summary: Hope is more than wishful thinking — it is a distinct emotional experience that reliably supports a sense of meaning in life. A multi-study analysis by researchers at the University of Missouri finds that hope outperforms other positive emotions as the most consistent predictor of perceived life meaning, with implications for psychological well-being. Across … Read more
