By amplifying a version of a bird's distress call, air safety engineers have developed a way to keep birds from being sucked into a plane's engine. Another technological advance for air travel is the Tempest IC, a satellite connection using a TV-like device that air medical officers can use to transmit a passenger's vital signs to a medical station on the ground. Strides in cleaner energy include a large solar power plant working at full capacity in Portugal, new solar panels that also grab the heat to make hot water, and challenges in carbon-capture technology for coal-fired plants. More than 400 years after Rembrandt’s birth, a new exhibition of his work features high-end digital reproductions of his paintings, showing them as they would have looked when they were first completed. Researchers in Massachusetts study the genetic structure of tumors, hoping to find ways to determine the right match of drugs for treatment. In Australia, scientists are looking to make advances in treating motor-neuron disease. Turning to robots to help solve puzzle, researchers attach rat brain cells to computer chips in an attempt to discover how brain cells work, while others study evolution by building robots as stand-ins for long extinct creatures.
