Caltech researchers develop quick, low-cost, and portable microchip for immune monitoring and clinical applications There's a wealth of health information hiding in the human immune system. Accessing it, however, can be very challenging, as the many and complex roles that the immune system plays can mask the critical information that is relevant to addressing specific health issues. Now, research led by scientists from the California Institute of Technology (Caltech) has shown that a new...

Silicon-based film may lead to efficient thermoelectric devices Computers, light bulbs, and even people generate heat"”energy that ends up being wasted. With a thermoelectric device, which converts heat to electricity and vice versa, you can harness that otherwise wasted energy. Thermoelectric devices are touted for use in new and efficient refrigerators, and other cooling or heating machines. But present-day designs are not efficient enough for widespread commercial use or are made...

Researchers at the California Institute of Technology (Caltech) have devised a new technique"”using a sheet of carbon just one atom thick"”to visualize the structure of molecules. The technique, which was used to obtain the first direct images of how water coats surfaces at room temperature, can also be used to image a potentially unlimited number of other molecules, including antibodies and other biomolecules.A paper describing the method and the studies of water layers appears...
