Biomedical breakthrough: Carbon nanoparticles you can make at home
Posted on June 19, 2015
Science Daily NewsResearchers have found an easy way to produce carbon nanoparticles that are small enough to evade the body's immune system, reflect light in the near-infrared range for easy detection, and carry payloads of pharmaceutical drugs to targeted tissues. The new approach generates the particles in a few hours and uses only a handful of ingredients, including store-bought molasses.
What is nanotechnology?

Nanotechnology brings together electronics, physics, chemistry, biology, and materials science to create new functional systems of nanoscale dimensions, offering new possibilities in electronics, medicine, and information technology, alongside more mundane but equally fascinating improvements in cosmetics, coatings, fabrics, and lubrication. The technological challenges range from finding out how nanoparticles can improve sun cream and how nanostructured surfaces can keep clothes clean, to learning how the revolutionary steps in quantum computing, smart drug delivery, and information storage may be achieved.
Robot to 3D print a steel bridge (Video)
Posted on June 25, 2015
Watch the videoDutch startup company MX3D plans to build the world's first 3D printed bridge across an Amsterdam canal. The company hopes the technique could become standard on future construction projects. The multi-axis technique works by 3D printing metal that melts then solidifies within a second. Aided by the geometry of the overall bridge design, the strength of the metal, and support from the edge of the canal and the robot, the material is able to print horizontally without bending and falling into the water.

The skirt and shoe made of kombuchaWhat might our clothes look like in 50 years? When textile designer Suzanne Lee was researching her book, Fashioning the Future, she found the most interesting answers to that question when she looked beyond the traditional borders of fashion design. Beyond cut, color and cloth, our style in 50 years will be driven by new materials from the corners of science. With biologists, engineers and materials scientists, she realized, she could create an entirely new strain of fashion.

Researchers Use 3D Printing to Produce Eardrum Scaffold
Posted on June 19, 2015
FUll ArticleOne of the more notable factors affecting the field of medical 3D printing is the simple 'cool' factor in looking at how far we have come from treatments of times long past. A common ailment, requiring medical attention through the ages, has been a perforated eardrum, which can occur due to trauma, infection, or Q-Tips.
Two different techniques were examined in the course of the research conducted, both creating scaffolds using FDA-approved copolymers designed to host cellular growth. These scaffolds were similar in size to natural eardrums, designed to have a 15mm diameter and 100µm thickness.
