With two pairs of fine-tipped tweezers and the hands of a surgeon, Cheryl Hayashi began dissecting the body of a silver garden spider under her microscope. In just a few minutes, she found what she was seeking: hundreds of silk glands, the organs spiders use to make their webs. Some looked like mashed potatoes, others
Biochemical engineers at Johns Hopkins University have used sequences of DNA molecules to induce shape-changing in water-based gels, demonstrating a new tactic to produce soft robots and “smart” medical devices that do not rely on cumbersome wires, batteries or tethers. The research advance, supervised by three faculty members in the university’s Whiting School of Engineering,
