Summary: Researchers have developed a method to print microelectrode arrays directly onto gelatin candies and other soft substrates, a step that could enable new diagnostic and therapeutic bioelectronic devices. Source: TUM Microelectrode arrays (MEAs) enable direct measurement of electrical signals from tissues such as the brain and heart, but conventional MEAs are typically rigid. A … Read more

Summary: Researchers report that synthetic marijuana products sold under names such as K2 or Spice can cause severe health problems — including psychosis, seizures, kidney and heart injury, dependence, and even death. These products are chemically different from cannabis and are not safe substitutes. Source: Cell Press. Synthetic marijuana compounds are promoted as legal, undetectable … Read more

Summary: New research shows the coordinated activity of the striatum and hippocampus enhances adolescents’ learning and memory formation. Source: Zuckerman Institute. Columbia-led study links adolescent memory performance with reward-driven learning and specific brain connectivity. Researchers have identified a distinctive characteristic of the adolescent brain that appears to support learning and the formation of lasting memories: … Read more

Summary: New research provides evidence that specific human herpesviruses are associated with Alzheimer’s disease. The study found higher levels of human herpesvirus 6A (HHV‑6A) and human herpesvirus 7 (HHV‑7) in brain tissue with Alzheimer’s neuropathology, and describes network-level interactions that suggest viral activity may contribute to disease mechanisms. Source: Arizona State University. Alzheimer’s disease remains … Read more

Summary: Researchers found that music—especially listeners’ own favorite tracks—can lessen how intensely people experience pain. In the experiment, participants reported lower pain intensity and reduced unpleasantness when listening to their favorite music compared with unfamiliar relaxing pieces or silence. The emotional character of the music mattered: songs described as “moving” or “bittersweet” were particularly effective. … Read more

Summary: A global study shows that the music we find most emotionally powerful usually comes from our teenage years, with a clear peak around age 17. This pronounced “reminiscence bump” reflects how songs experienced during adolescence become deeply tied to identity and long-lasting memory. The study also identifies gender differences: men’s strongest musical memories tend … Read more

Summary: After injury, insulin is essential for the maturation and survival of newly generated olfactory sensory neurons, supporting recovery of the sense of smell. Source: Monell Chemical Senses Center Researchers have long recognized insulin’s role in the growth and repair of certain sensory neurons that convey environmental information to the brain, such as those involved … Read more

Summary: New research indicates that social media interactions can help reduce negative emotions and support well-being for people who feel uneasy in direct, one-on-one social encounters.
