Do-it-yourself invisibility cloaking with 3D printing

Yaroslav Urzhumov and the 3D-printed invisibility cloak (credit: Duke University) Seven years ago, Duke University engineers demonstrated the first working invisibility cloak in complex laboratory experiments. Now it appears creating a simple cloak has become a lot simpler, by using a 3D printer.. Yaroslav Urzhumov, assistant research professor in electrical and computer engineering at Duke’s Pratt School of Engineering, […]

First fully 3D-printed gun test-fired

Defense Distributed founder Cody Wilson has test-fired the world’s first fully 3D-printed gun — “the Liberator.” The CAD file is downloadable* at DEFCAD, operated by Defense Distributed — a “makeshift response to Makerbot Industries’ decision to censor files uploaded in good faith at Thingiverse, specifically firearms-related files.” More Meet The ‘Liberator’: Test-Firing The World’s First Fully 3D-Printed Gun Guns […]

NANOSCALE CAPSULE KILLS CANCER CELLS WITHOUT HARMING HEALTHY CELLS

A diagram of the synthesis of degradable nanocapsules into cell nuclei to induce apoptosis, or programmed cell death, in cancer cells. The nanocapsules degrade harmlessly in normal cells. (Credit: UCLA Engineering) A degradable nanoscale shell to carry proteins to cancer cells and stunt the growth of tumors without damaging healthy cells has been developed by a team […]

DARPA LOOKING FOR TECHNOLOGY TO CREATE ‘TRANSIENT ELECTRONICS’ DEVICES

Salvador Dali painting? No, Vanishing Programmable Resources (VAPR) (credit: DARPA) The sophisticated electronics used by warfighters in everything from radios, remote sensors and even phones can now be made at such a low cost that they are pervasive throughout the battlefield. But it is almost impossible to track and recover every device. These electronics are […]

A STAR TREK ‘TRACTOR’ BEAM FOR MICROSCOPIC OBJECTS

In the experimental system, a light beam is converted into a pulling device that gathers microscopic (<5 microns) polystyrene spheres,  like when using a chain (credit: University of St Andrews) A miniature “tractor” beam that allows a beam of light to attract objects (as featured in Star Trek movies) has been created by researchers from the University of St Andrews and […]

CHEAP, EASY TECHNIQUE TO SNIP DNA COULD REVOLUTIONIZE GENE THERAPY

A simple, precise, and inexpensive method for cutting DNA to insert genes into human cells could transform genetic medicine, making routine what now are expensive, complicated and rare procedures for replacing defective genes to fix genetic disease or even cure AIDS. Discovered last year, two new papers published last week in the journal Science Express demonstrate that the […]

RESEARCHERS CREATE LASER THE SIZE OF A VIRUS PARTICLE

Plasmonic lasers (credit: Jae Yong Suh et al./NANO Letters) A Northwestern University research team has found a way to manufacture single laser devices that are the size of the smallest virus (about 20 nm.) and operate at room temperature. These plasmonic nanolasers could be readily integrated into silicon-based photonic devices, all-optical circuits, and nanoscale biosensors. Reducing the size of […]

Carbon nanotubes to replace silicon: IBM

IBM carbon nanotube: The substrate gets dipped in the carbon nanotube solution and the nanotubes attach via a chemical bond to the coating in the HfO2 trenches (credit: IBM) IBM scientists have precisely placed and tested more than 10,000 carbon nanotube devices in a single chip, using standard semiconductor manufacturing processes — paving the way for carbon technology to replace silicon […]
