(Nanowerk News) Artificial helical microswimmers with shape-morphing capabilities and adaptive locomotion are promising for precision medicine and noninvasive surgery. However, current fabrication ...

For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a ...

The helix is a popular shape in engineering. It is used in our screws to ensure a strong hold, in our springs to store mechanical energy, even in our pastas to capture the right amount of sauce. It is ...

Researchers at the Georgia Institute of Technology have developed a new class of nanometer-scale structures that spontaneously form helical shapes from long ribbon-like single crystals of zinc oxide ...

James D. Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died. He was 97. The ...

Microorganisms, such as bacteria and sperm, can undergo adaptive shape morphing to optimize their locomotion mechanisms in the environment, which enables them to navigate complex barriers and improve ...

Schematic illustration of highly efficient fabrication of stimuli-responsive microhelix based on the rotary holographic processing method. The adaptive locomotion of shape-morphing helical ...
