Needle beam could eliminate signal loss in on-chip optics

(Phys.org)—An international, Harvard-led team of researchers have demonstrated a new type of light beam that propagates without spreading outwards, remaining very narrow and controlled along an unprecedented distance. This ...

New technique scales up nanofiber production

(PhysOrg.com) -- A new spin on an old technology will give scientists and manufacturers the ability to significantly increase their production of nanofibers, according to researchers at North Carolina State University.

Painless microneedle patch could replace needles

It's only a matter of time before drugs are administered via patches with painless microneedles instead of unpleasant injections. But designers need to balance the need for flexible, comfortable-to-wear material with effective ...

Molecular ruler sets bacterial needle length

When a salmonella bacterium attacks a cell, it uses a nanoscopic needle to inject it with proteins to aid the infection. If the needle is too short, the cell won't be infected. Too long, and the needle breaks. Now, University ...

Researchers measure puncture performance of viper fangs

A team that studies how biological structures such as cactus spines and mantis shrimp appendages puncture living tissue has turned its attention to viper fangs. Specifically, the scientists wanted to know, what physical characteristics ...

Team introduces novel method to grow elastic diamonds

Diamond is the strongest naturally occurring material on Earth. It is also renowned for its high stiffness, exceptional thermal conductivity, high chemical resistance, and high optical transparency. Although these remarkable ...
