Duke University Creates “Perfect” Microwave Cloak

Scientists have been able to successfully cloak an object, rendering a centimeter-scale cylinder invisible to microwaves. Many different invisibility cloaks have been demonstrated, but all of those reflect some of the incidental light, making the illusion incomplete. This is the first to cloak an object perfectly. The scientists published their findings in the journal Nature Materials. […]

NASA’s 3-D Printing of Rocket Engine Parts Might Boost Larger Manufacturing Trend

NASA’s Space Launch System (SLS) is its first heavy-lift booster rocket since Saturn 5 took US astronauts to the moon. SLS will play a central role in the future of American spaceflight, but might also provide a critical test for technology expected to revamp the country’s ailing manufacturing industry. Selective Laser Melting (SLM) is being used at […]

Jellyfish-Inspired Microchip Can Be Used to Capture Cancer Cells

Scientists have built a jellyfish-inspired microchip that can capture cancer and other rare cells in human blood. The scientists published their findings in the journal Proceedings of the National Academy of Sciences. Jellyfish capture food particles with their long tentacles, which are equipped with repeating patterns of sticky structures. Researchers at Brigham and Women’s Hospital in […]

Stanford’s Self-Healing Plastic Skin Could Lead to Improved Prosthetics

Researchers in California have developed a synthetic version of skin that’s flexible, electrically conductive, and self-healing. The scientists published their findings in the journal Nature Nanotechnology. There has been a small boom in the last decade in the development of epidermal electronics, thin and flexible circuits that can be attached to skin or provide skin-like touch […]
