Nature Biotechnology
Breakthrough nanoparticle halts multiple sclerosis
In a breakthrough for nanotechnology and multiple sclerosis (MS), a biodegradable nanoparticle delivers an antigen that tricks the immune system and halts MS in mice. The approach, the first that doesn't suppress the immune system, is being tested in a clinical trial for MS patients, but with white blood cells delivering the antigen. The nanoparticle is an easier, cheaper option and can be used in other immune-related diseases including Type 1 diabetes, food and airway allergies.

New program draws young artists into science
Artists and scientists often share a common goal: making the invisible visible. Yet artistically talented students, especially girls, often shy away from scientific careers. A new four-year, $1.2 million program led by the University of Alaska Fairbanks blends the art, biology and physics of color into a series of summer academies, science cafes and activity kits designed to inspire art-interested students to enter careers in science.

Medical vital-sign monitoring reduced to the size of a postage stamp
Electrical engineers have developed new technology to monitor medical vital signs, with sophisticated sensors so small and cheap they could fit onto a bandage, be manufactured in high volumes and cost less than a quarter. When commercialized, the technology could have many potential applications due to its powerful performance, small size, and low cost.

These bots were made for walking: Cells power biological machines
They're soft, biocompatible, about 7 millimeters long -- and, incredibly, able to walk by themselves. Miniature "bio-bots" developed at the University of Illinois are making tracks in synthetic biology. The walking bio-bots demonstrate the Illinois team's ability to forward-engineer functional machines using only hydrogel, heart cells and a 3-D printer. The bio-bots could be customized for specific applications in medicine, energy or the environment.

Physicists skirt thermal vibration, transfer optical signal via mechanical oscillator
Using tiny radiation pressure forces, physicists converted an optical field, or signal, from one color to another, aided by a "dark mode." The conversion occurs through the coupling between light and a mechanical oscillator, without interruption by thermal mechanical vibrations.

Optical microscopes lend a hand to graphene research
The remarkable properties and subsequent applications of graphene have been well-documented since it was first isolated in 2004; however, researchers are still trying to find a quick, cheap and efficient way of measuring its thickness.

Wax-filled nanotech yarn behaves like powerful, super-strong muscle
New artificial muscles made from nanotech yarns and infused with paraffin wax can lift more than 100,000 times their own weight and generate 85 times more mechanical power during contraction than the same size natural muscle, according to scientists at the University of Texas at Dallas and their international team. The artificial muscles are yarns constructed from carbon nanotubes.

NIST study suggests carbon nanotubes may protect DNA from oxidation
NIST researchers have provided evidence that single-wall carbon nanotubes may help protect DNA molecules from damage by oxidation, which can lead to mutations. More studies are needed to see if the in vitro protective effect of nanotubes reported in the laboratory also occurs in vivo, that is, within a living organism.

'Cloning' could make structurally pure nanotubes for nanoelectronics
Researchers from the University of Southern California and NIST have demonstrated a technique for growing virtually pure samples of single-wall carbon nanotubes with identical structures, a process they liken to "cloning" the nanotubes. If it can be suitably scaled up, their approach could solve an important materials problem in nanoelectronics: producing carbon nanotubes of a specific structure to order.

Paper-and-scissors technique rocks the nano world
Sometimes simplicity is best. Northwestern University researchers have discovered an easy way to make nanofluidic devices: using paper and scissors. And they can cut a device into any shape and size, adding to the method's versatility. Nanofluidic devices are attractive because their thin channels can transport ions -- and with them a higher than normal electric current -- making them promising for use in batteries and new systems for water purification, harvesting energy and DNA sorting.

Nanometer-scale diamond tips improve nano-manufacturing
One of the most promising innovations of nanotechnology has been the ability to perform rapid nanofabrication using nanometer-scale tips. The fabrication speed can be dramatically increased by using heat. High speed and high temperature have been known to degrade the tipů until now. Researchers have created a new type of nano-tip for thermal processing, which is made entirely out of diamond.

New freeform standards to support scanning CMMs
The National Physical Laboratory, the UK's National Measurement Institute, has developed a new range of three dimensional standards for verifying freeform coordinate measurement machines. The standard allows the verification of portable and fixed non-contact coordinate measuring systems such as those employing laser scanning and fringe projection technologies, as well as those employing tactile sensors. It also helps evaluate the surface measurement capabilities of new scanning measurement technologies.

UT Arlington physics team demonstrates new power generation technique
University of Texas at Arlington and Louisiana Tech University researchers created a hybrid nanomaterial that can be used to convert light and thermal energy into electrical current. The team built a prototype thermoelectric generator they hope can eventually produce milliwatts for use in devices such as self-powering sensors, low-power electronic devices and implantable biomedical micro-devices, they said. UT Arlington's Wei Chen has also coupled gold nanoparticles with copper sulfide nanoparticles for potential use in cancer therapy.

Detection, analysis of 'cell dust' may allow diagnosis, monitoring of brain cancer
A novel miniature diagnostic platform using nuclear magnetic resonance technology is capable of detecting minuscule cell particles known as microvesicles in a drop of blood. Microvesicles shed by cancer cells are even more numerous than those released by normal cells, so detecting them could prove a simple means for diagnosing cancer.
