• 'Dancing molecules' heal cartilage damage July 26, 2024
  New therapy uses synthetic nanofibers to mimic the natural signaling of a protein that is crucial for cartilage formation and maintenance. Researchers found that intensifying the motion of molecules within the nanofibers led to more components needed for regeneration. After just four hours, the treatment activated the gene expression necessary to generate cartilage. Therapy could […]
• New understanding of fly behavior has potential application in robotics, public safety July 26, 2024
  Scientists have identified an automatic behavior in flies that helps them assess wind conditions -- its presence and direction -- before deploying a strategy to follow a scent to its source. The fact that they can do this is surprising -- can you tell if there's a gentle breeze if you stick your head out […]
• Lampreys possess a 'jaw-dropping' evolutionary origin July 26, 2024
  Lampreys are one of only two living jawless vertebrates Jaws are formed by a key stem cell population called the neural crest New research reveals the gene regulatory changes that may explain morphological differences between jawed and jawless vertebrates.
• Researchers develop state-of-the-art device to make artificial intelligence more energy efficient July 26, 2024
  Engineering researchers have demonstrated a state-of-the-art hardware device that could reduce energy consumption for artificial intelligent (AI) computing applications by a factor of at least 1,000.
• New drug shows promise in clearing HIV from brain July 25, 2024
  An experimental drug originally developed to treat cancer may help clear HIV from infected cells in the brain, according to a new study. By targeting infected cells in the brain, drug may clear virus from hidden areas that have been a major challenge in HIV treatment.
