High-tech prosthetics allow amputees to engage more fully in everyday life, even to compete in sporting events. Researchers have demonstrated how brain activity is used to identify different terrains — level ground and stairs, for example — a key step in developing prosthetics that allow the user’s prosthesis to automatically adjust to changing ground conditions in real time.

Going swimmingly: Biotemplates breakthrough paves way for cheaper nanobots

New developments may now propel nanoswimmers from science fiction to reality thanks to unexpected help from bacteria. Engineers have demonstrated a new technique for plating silica onto flagella, the helix-shaped tails found on many bacteria, to produce nanoscale swimming robots. The group’s biotemplated nanoswimmers spin their flagella thanks to rotating magnetic fields and can perform nearly as well as living bacteria.

Deducing the properties of a new form of diamond

Earlier this year, amorphous diamond was synthesized for the first time using a technique involving high pressures, moderately high temperatures and a tiny amount of glassy carbon as starting material. A father-son team at Clemson University has now successfully calculated a number of basic physical properties for this new substance, including elastic constants and related quantities.

New treatment investigated for brain tapeworm infection

Treating neurocysticercosis (NCC), an infection of the brain with tapeworm larvae, often leads to inflammation and seizures when the parasites in the brain die. Now, researchers have reported that pretreatment with the anti-tumor necrosis factor drug etanercept (ETN) is a viable strategy to manage this post-treatment inflammation.
