  • Mantis shrimp stronger than airplanes: Composite material inspired by shrimp stronger than standard used in airplane frames
    Inspired by the fist-like club of a mantis shrimp, researchers have developed a design structure for composite materials that is more impact resistant and tougher than the standard used in airplanes. The peacock mantis shrimp, or stomatopod, is a 4- to 6-inch-long rainbow-colored crustacean with a fist-like club that accelerates underwater faster than a 22-c […]
  • A new 'APEX' in plant studies aboard the International Space Station
    Growing knowledge in a given field takes time, attention, and ... water? It does when you're talking about plant studies aboard the International Space Station (ISS). All of these things and some scientific know-how come into play as astronauts find out just how green their thumbs are while assisting researchers on the ground.
  • For an immune cell, microgravity mimics aging
    Telling someone to "act your age" is another way of asking him or her to behave better. Age, however, does not always bring improvements. Certain cells of the immune system tend to misbehave with age, leaving the elderly more vulnerable to illness. Because these cells are known to misbehave similarly during spaceflight, researchers are studying the […]
  • First size-based chromatography technique for the study of livi
    Using nanodot technology, researchers demonstrated the first size-based form of chromatography for studying the membranes of living cells. This unique physical approach to probing cellular membrane structures reveals critical information that can't be obtained through conventional microscopy.
  • Applying math to biology: Software identifies disease-causing mutations in undiagnosed illnesses
    A computational tool has successfully identified diseases with unknown gene mutations in three separate cases. Sequencing the genomes of individuals or small families often produces false predictions of mutations that cause diseases. But this study shows that a new unique approach allows it to identify disease-causing genes more precisely than other computat […]
