Specialized bacterial filaments shown to conduct electricity Some bacteria grow electrical hair that lets them link up in big biological circuits, according to a University of Southern California biophysicist and his collaborators. The finding suggests that microbial colonies may survive, communicate and share energy in part through electrically conducting hairs known as bacterial nanowires. "This is the first measurement of electron transport along biological nanowires produced by bacteria,"...

Dentists and their patients will soon benefit from a tiny new high-resolution X-ray camera. A Swedish company has adapted an advanced technique used for miniaturizing space hardware to make a visit to the dentist a little more comfortable. The camera takes X-ray pictures that are dramatically more detailed and with higher contrast than the conventional X-ray machines widely used by dentists today. The heart of the camera is a tiny "Ëœstructured scintillator' device that converts...

While refining their novel method for making nanoscale wires, chemists at the National Institute of Standards and Technology (NIST) discovered an unexpected bonus"”a new way to create nanowires that produce light similar to that from light-emitting diodes (LEDs). These "nano-LEDs" may one day have their light-emission abilities put to work serving miniature devices such as nanogenerators or lab-on-a-chip systems.Nanowires typically are "grown" by the controlled deposition of...

Silicon-based film may lead to efficient thermoelectric devices Computers, light bulbs, and even people generate heat"”energy that ends up being wasted. With a thermoelectric device, which converts heat to electricity and vice versa, you can harness that otherwise wasted energy. Thermoelectric devices are touted for use in new and efficient refrigerators, and other cooling or heating machines. But present-day designs are not efficient enough for widespread commercial use or are made...

U.S. researchers said Sunday that new artificial "skin" fashioned out of flexible semiconductor materials can sense touch, making it possible for robots to be able to grip eggs but be strong enough to hold a frying pan as well. Scientists have been struggling with a way to try and make robots be able to adjust the amount of force needed to hold different objects.  The pressure-sensitive materials are designed to help overcome that challenge. Ali Javey, an electrical engineer at the...

Strain-gating Researchers at the Georgia Institute of Technology have developed a new class of electronic logic device in which current is switched by an electric field generated by the application of mechanical strain to zinc oxide nanowires. The devices, which include transistors and diodes, could be used in nanometer-scale robotics, nano-electromechanical systems (NEMS), micro-electromechanical systems (MEMS) and microfluidic devices. The mechanical action used to initiate the strain could...

Breakthrough discovery enables nanoscale manipulation of the piezoelectric effect The generation of an electric field by the compression and expansion of solid materials is known as the piezoelectric effect, and it has a wide range of applications ranging from everyday items such as watches, motion sensors and precise positioning systems. Researchers at McGill University's Department of Chemistry have now discovered how to control this effect in nanoscale semiconductors called "quantum dots,"...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
