(University of Illinois at Urbana-Champaign) A new ink, composed of silver nanoparticles, can be used in electronic and optoelectronic applications to create flexible, stretchable and spanning microelectrodes that carry signals from one circuit element to another. The printed microelectrodes can withstand repeated bending and stretching with minimal change in their electrical properties.

(DOE/Ames Laboratory) Scientists at the US Department of Energy's Ames Laboratory have shown that nanoscale, uniform lead islands on silicon are spontaneously and quickly created by unusually mobile atoms. The discovery of the "liquid-like" nanogrowth mechanism is promising for nanotechnology applications, which require fast, consistent, and efficient material growth for industrial-scale production.

(North Carolina State University) Researchers at North Carolina State University have successfully modified a common plant virus to deliver drugs only to specific cells inside the human body, without affecting surrounding tissue. These tiny "smart bombs" -- each one thousands of times smaller than the width of a human hair -- could lead to more effective chemotherapy treatments with greatly reduced, or even eliminated, side effects.

(University of Copenhagen) Researchers from Nano-Science Center, University of Copenhagen and National Center for Scientific Research, France, have developed a general method to study membrane proteins. This method can be used to screen several thousand proteins, and it will reduce the way from development to useful drugs substantially. Already now the pharmaceutical industry is interested and participate in a European consortium that is under con... More

Dark comets may be prowling the solar system, posing a deadly threat to Earth. They are formed when reflective water ice has evaporated away, leaving behind an organic crust that only reflects a small fraction of light.

A new new kind of thought-controlled artificial arm that moves more easily than other devices has been developed by Johns Hopkins University researchers. The technique, called targeted muscle reinnervation, involves taking the nerves that remain after an arm is amputated and connecting them to another muscle in the body, often in the chest. Electrodes are placed over the chest muscles, acting as antennas. When the person wants to move the arm, th... More

(Yale University) Yale engineers have created a process that may revolutionize the manufacture of nano-devices from computer chips to biomedical sensors by exploiting a novel type of metal. The material can be molded like plastics to create features at the nanoscale and yet is more durable and stronger than silicon or steel. The work is reported in the Feb. 12 issue of Nature.
