Safer robots will improve manufacturing | KurzweilAI - 0 views

  •  
    Robots have been considered too unpredictable and dangerous to work alongside humans in factories, but improved technologies for artificial sensing and motion are leading to a new wave of safer robots. Last winter, NASA sent a humanoid robot dubbed Robonaut 2 (R2) to the International Space Station. R2, which has only a torso, sophisticated arms and fingers, and a head full of sensors, jointly developed by NASA and General Motors under a program to create a robot that could operate safely alongside humans. R2 uses a popular robotics technology called series elastic actuators in its joints. The actuators have an elastic spring component between the motor and the object the robot has to pick up. The actuators help the robot detect and control the force of its own movements. R2 is also covered in soft material in case of accidental collisions, and its head contains cameras so it can keep track of its human colleagues. In June, President Obama announced a $500 million federal investment in manufacturing technology (including $70 million for robotics). It represents another step in developing robots that can assist with repetitious or physically stressful assembly-line tasks without posing a safety risk.

Mass-producing stem-cells for stem cells for diagnostic and therapeutic applications | ... - 0 views

  •  
    Todd McDevitt at the Georgia Institute of Technology and colleagues have found that adding biomaterials such as gelatin into clumps of stem cells (called "embryoid bodies") affected stem-cell differentiation without harming the cells. By incorporating magnetic particles into the biomaterials, they could control the locations of the embryoid bodies and how they assemble with one another. Compared to typical delivery methods, providing differentiation factors - retinoic acid, bone morphogenetic protein 4 (BMP4) and vascular endothelial growth factor (VEGF) - via microparticles induced changes in the gene and protein expression patterns of the aggregates. In the future, these new methods could be used to develop manufacturing procedures for producing large quantities of stem cells for diagnostic and therapeutic applications. The findings were presented on June 16 at the annual meeting of the International Society for Stem Cell Research. [full text]
