New 3-D printing approach makes cell-scale lattice structures

A new way of making scaffolding for biological cultures could make it possible to grow cells that are highly uniform in shape and size, and potentially with certain functions. The new approach uses an extremely fine-scale ...

Revolutionary imaging technique uses CRISPR to map DNA mutations

A team of scientists led by Virginia Commonwealth University physicist Jason Reed, Ph.D., have developed new nanomapping technology that could transform the way disease-causing genetic mutations are diagnosed and discovered. ...

Tattoos mark the spot—for surgery—then disappear

Tattoos aren't just for body art. They can have medical applications, too. Doctors are using them on patients to mark an area for future treatment—particularly for non-melanoma skin cancer such as basal cell carcinoma—but ...

Mussel power: Researches develop underwater glue

Even the strongest glues collapse when soaked. Just watch a band-aid slide ungracefully off a finger or toe while in the shower. However, with support from the Office of Naval Research (ONR), one researcher has developed ...

Learning from nature's silky skills

Why have we never been able to manufacture fibers as strong and tough as the silks spun by silkworms and spiders?

Microrobots armed with new force-sensing system to probe cells

Inexpensive microrobots capable of probing and manipulating individual cells and tissue for biological research and medical applications are closer to reality with the design of a system that senses the minute forces exerted ...
