Science
Researchers develop completely new kind of polymer
Imagine a polymer with removable parts that can deliver something to the environment and then be chemically regenerated to function again. Or a polymer that can contract and expand the way muscles do. These functions require polymers with both rigid and soft nano-sized compartments with extremely different properties. Northwestern University researchers have developed a hybrid polymer of this type that might one day be used in artificial muscles; for delivery of drugs or biomolecules; in self-repairing materials; and for replaceable energy sources.

A step towards keeping up with Moore's Law
Professor Tae-Woo Lee and his research team at POSTECH, Korea, have developed a rapid printing technology for high density and scalable memristor array composed of cross-bar-shaped metal nanowires. This technology will be used as a source technology to realize smart fabric, wearable computers, and textile electronic devices as it reduces lead time and cost remarkably compared with existing manufacturing methods. Their findings were published in Advanced Materials.

Small is different
In the production of margarine millions of tons of unsaturated fatty acids are converted from vegetable oils using hydrogen. While searching for improved catalysts for these so-called hydrogenation reactions, a German-American research team made a discovery that puts a 50-year old rule in question: In catalytic particles comprising only a few atoms, shape and size influence reactivity much more strongly then previously thought.

Too-few proteins prompt nanoparticles to clump
Low concentrations of serum albumin proteins have the ability to bind one-to-one to gold nanoparticles and, upon unfolding, prompt them to aggregate, according to Rice University scientists. The finding may be important to those who study diseases caused by protein aggregation or nanoparticle toxicity.

Scientific education through films?
Magic swords, wands, cauldrons and cloaks of invisibility do not exist in reality. In contrast, it is possible that scenarios like crashed aircrafts looming out of the mists of an alien planet, patients being snatched from the jaws of death by a risky medical breakthrough, or smug murderers who are betrayed by a few molecules left at the scene of crime are part of our current or future reality.

NASA Webb Telescope mirrors installed with robotic arm precision
Inside a massive clean room at NASA's Goddard Space Flight Center in Greenbelt, Maryland the James Webb Space Telescope team is steadily installing the largest space telescope mirror ever. Unlike other space telescope mirrors, this one must be pieced together from segments using a high-precision robotic arm.

Soft robotic grippers non-destructively manipulate deep sea coral reef organisms
The first use of soft robotics in the deep sea describes the non-destructive interaction and sampling of fragile organisms in their natural environments. The design and grasping capabilities of these innovative soft robotic grippers and their successful use at deep sea depths are described in an article in Soft Robotics.

Cellulose nanogenerators could one day power implanted biomedical devices
Implantable electronics that can deliver drugs, monitor vital signs and perform other health-related roles are on the horizon. But finding a way to power them remains a challenge. Now scientists have built a flexible nanogenerator out of cellulose, an abundant natural material, that could potentially harvest energy from the body -- its heartbeats, blood flow and other almost imperceptible but constant movements. Their report appears in the journal ACS Applied Materials & Interfaces.

Scientists build a neural network using plastic memristors
A group of Russian and Italian scientists have created a neural network based on polymeric memristors -- devices that can potentially be used to build fundamentally new computers. These developments will primarily help in creating technologies for machine vision, hearing, and other machine sensory systems, and also for intelligent control systems in various fields of applications, including autonomous robots.

Designing a pop-up future
What if you could make any object out of a flat sheet of paper? That future is on the horizon thanks to new research from the the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS). A team of researchers have characterized a fundamental origami fold, or tessellation, that could be used as a building block to create almost any three-dimensional shape, from nanostructures to buildings.

New fluorescent nanomaterials whose inspiration was taken from plant antenna systems
One of the biggest temptations facing a scientist is to try and reproduce natural phenomena which are so fascinating given their effectiveness and perfection. This is the aim being pursued by the UPV/EHU's Molecular Spectroscopy Group which, coinciding with the International Year of Light, has designed a set of fluorescent nanomaterials which have taken their inspiration from the antenna systems of plants.
