When small objects get stuck to you, a vacuum or lint roller can help remove them. But small, clingy objects are a serious problem in the growing field of nanomanufacturing. So what do engineers use when they have to build circuits that will fit on a piece of confetti? Researchers supported by the National Science Foundation (NSF) have a solution: lasers.

The tiny tube circled an ant's thorax, gently trapping the insect and demonstrating the utility of a microrobotic tentacle developed by Iowa State Univ. engineers. While most robots squeeze two fingers together to pick things up, these tentacles wrap around items gently.
Researchers 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. Unlike other methods of making carbon nanoparticles, the new approach generates the particles in a few hours and uses only a handful of ingredients, including store-bought molasses.
Someday, treating patients with nanorobots could become standard practice to deliver medicine specifically to parts of the body affected by disease. But merely injecting drug-loaded nanoparticles might not always be enough to get them where they need to go. Now scientists are reporting in Nano Letters the development of new nanoswimmers that can move easily through body fluids to their targets.
A group of researchers at Chalmers Univ. of Technology have managed to print and dry 3-D objects made entirely by cellulose, for the first time, with the help of a 3-D bioprinter. They also added carbon nanotubes to create electrically conductive material.
Researchers in the Cockrell School of Engineering at The Univ. of Texas at Austin have developed a groundbreaking new energy-absorbing structure to better withstand blunt and ballistic impact. The technology, called negative stiffness honeycombs, can be integrated into car bumpers, military and athletic helmets and other protective hardware.
The effort to secure a stable, domestic source of a critical medical isotope reached an important milestone this month as the U.S. Dept. of Energy's Argonne National Laboratory demonstrated the production, separation and purification of molybdenum-99 (Mo-99) using a process developed in cooperation with SHINE Medical Technologies.
At the International Conference on Robotics and Automation, Massachusetts Institute of Technology researchers presented a printable origami robot that folds itself up from a flat sheet of plastic when heated and measures about a centimeter from front to back. Weighing only a third of a gram, the robot can swim, climb an incline, traverse rough terrain and carry a load twice its weight.
A Massachusetts Institute of Technology team has developed a way of making soft materials, using a 3-D printer, with surface textures that can then be modified at will to be perfectly smooth, or ridged or bumpy, or even to have complex patterns that could be used to guide fluids.
A team of researchers from the Univ. of Twente has found a way to 3D print structures of copper and gold, by stacking microscopically small metal droplets. These droplets are made by melting a thin metal film using a pulsed laser.
Synthesizing nanoscale materials takes place within high-tech laboratories, where scientists in full-body suits keep every grain of dust away from their sensitive innovations. However, scientists at Kiel Univ. proved that this is not always necessary. They have successfully been able to transfer the experience from furnace to laboratory while synthesizing nanoscale materials using simple and highly efficient flame technology.
The future of 3D printing is bright and full of exciting promise. But the most intriguing scenario for this technology isn’t in the manufacture of objects we see every day—that will only be a small niche in the 3D-printing industry. Instead, 3D printing will realize its full potential when it enables people to innovate and create all new objects and devices in a one-touch process.
The need for improved performance of devices has led to the development of 3-D stacking of chips. Through-silicon via (TSV) has emerged as a viable and preferred technology for achieving such high-performance devices due to its short wiring length and reduced resistance and capacitance (RC) delay. It also offers the most design flexibility, lower manufacturing costs and allows for integration of heterogeneous chips.
A Si quantum dot (QD)-based hybrid inorganic/organic light-emitting diode (LED) that exhibits white-blue electroluminescence has been fabricated by a Hiroshima Univ. team.

Nanofibers have a huge range of potential applications, from solar cells to water filtration to fuel cells. But so far, their high cost of manufacture has relegated them to just a few niche industries. MIT researchers describe a new technique for producing nanofibers that increases the rate of production fourfold while reducing energy consumption by more than 90%, holding out the prospect of cheap, efficient nanofiber production.
Researchers discovered a large, previously unknown field of hydrothermal vents in the Gulf of California, about 100 miles east of La Paz, Mexico. Lying more than 12,500 feet below the surface, the Pescadero Basin vents are the deepest high-temperature hydrothermal vents ever observed in or around the Pacific Ocean. They are also the only vents known to emit superheated fluids rich in both carbonate minerals and hydrocarbons.
Biofuels pioneer Mascoma LLC and the BioEnergy Science Center have developed a revolutionary strain of yeast that could help significantly accelerate the development of biofuels from nonfood plant matter. The approach could provide a pathway to eventual expansion of biofuels production beyond the current output limited to ethanol derived from corn.

Decentralized partially observable Markov decision processes are a way to model autonomous robots’ behavior in circumstances where neither their communication with each other nor their judgments about the outside world are perfect. The problem with Dec-POMDPs is that they’re as complicated as their name. They provide the most rigorous mathematical models of multi-agent systems under uncertainty.
There’s an urgent demand for new antimicrobial compounds that are effective against constantly emerging drug-resistant bacteria.
