A University of Houston researcher disputes a study claiming multilingualism promotes healthy brain aging, finding that wealth and healthcare systems may drive longevity instead. Hernandez argues that individual behavioral solutions, such as learning a language, are oversold and distract from structural factors that support healthy aging.
Researchers at Tulane University discovered a new nerve cell signaling mechanism that can turn on pain signaling after injury, potentially leading to safer treatments. The discovery of enzyme vertebrate lonesome kinase (VLK) offers a new way to influence cell behavior and could simplify drug development.
Researchers have discovered that multimodal pain integration in the brain significantly enhances overall pain perception when participants are instructed on how to perceive the pain. The precuneus region of the brain plays a vital role in integrating pain information into a cohesive and intensified pain experience.
Researchers found that the new law allowing goalkeepers to put one foot in front of the line improved their penalty diving performance. The study, led by Paulo Roberto Pereira Santiago, used 3D body reconstruction technology and motion capture to analyze dives.
Convolutional neural networks trained to identify abnormalities on upper extremity radiographs are susceptible to a ubiquitous confounding image feature: radiograph labels. Covering these labels increases accuracy, while using them alone leads to decreased performance.
A University of Exeter study found that grey squirrels with strong left-right preferences performed poorly on a learning task, suggesting a negative relationship between laterality and cognitive performance. The researchers measured the speed of learning among over 30 squirrels to assess both learning and lateralization.
A study by Nagoya University researchers reveals that behavioral laterality in scale-eating fish is acquired through experience, with juveniles initially attacking both sides before favoring a dominant side. The stronger side's kinetic advantages support the theory that lateralized behavior is naturally determined.
Scientists have discovered a new mutation in the PKD1L1 gene associated with laterality defects and complex congenital heart disease. The study provides hope for affected families by offering prenatal or pre-implantation genetic diagnosis to prevent the condition from being passed on.
A study published in Springer's journal Behavioral Ecology and Sociobiology found that rainbowfish born in the wild are braver than those bred in captivity. The researchers suggest that fear is heightened when primarily processed by a single brain hemisphere, making lateralized fish less bold.
Researchers at Dartmouth College found that babies' babbling engages the language processing centers in the left hemisphere of the brain. The study used a technique called Laterality Index to measure mouth asymmetry and confirmed that this is linked to language development, not motor skills.
