MIPT-based researcher predicts new state of matter
A researcher with the Department of Electrodynamics of Complex Systems and Nanophotonics, Alexander Rozhkov, has presented theoretical calculations which indicate the possible existence of fermionic matter in apreviously unknown state -- in the form ofaone-dimensional liquid, which cannot be described within the framework of existing models

Laser physics upside down
A strange effect which has been predicted two years ago could now be experimentally verified. Coupled lasers can behave paradoxically, which makes them ideal components of interesting electro-optical switches.

Ultra-thin wires for quantum computing
Take a fine strand of silica fiber, attach it at each end to a slow-turning motor, torture it over a flame until it nearly reaches its melting point and then pull it apart. The middle will thin out like taffy until it is less than half a micron across, and that, according to researchers at the University of Maryland, is how you fabricate ultrahigh transmission optical nanofibers, a potential component for future quantum information devices.

Nanoshell shields foreign enzymes used to starve cancer cells from immune system
Nanoengineers at the University of California, San Diego have developed a nanoshell to protect foreign enzymes used to starve cancer cells as part of chemotherapy. Their work is featured on the June 2014 cover of the journal Nano Letters. Enzymes are naturally smart machines that are responsible for many complex functions and chemical reactions in biology. However, despite their huge potential, their use in medicine has been limited by the immune system, which is designed to attack foreign intruders.

Researchers use virus to reveal nanopore physics
Nanopores could provide a new way to sequence DNA quickly, but the physics involved isn't well understood. That's partly because of the complexities involved in studying the random, squiggly form DNA takes in solution. Researchers from Brown have simplified matters by using a stiff, rod-like virus instead of DNA to experiment with nanopores. Their research has uncovered previously unknown dynamics in polymer-nanopore interactions.

New advance allows gels to wiggle through water
Using a worm's contracting and expanding motion, researchers have designed a way for gels to swim in water. The advance, which is described in a Journal of Applied Polymer Science paper, involves the use of a hand-held laser to shrink and swell polymer gels comprised mostly of water.

Viewing deeper into the quantum world
Researchers at ICFO have experimentally demonstrated that interferometers, the most sensitive measuring instruments yet invented, can be improved using nonlinear physics. The result answers a fundamental question in quantum mechanics and could open the way to more sensitive detection of magnetic fields in delicate systems such as the human heart.

Elucidating optimal biological tissue shape during growth
A team of European scientists has now extended a previous biophysical model to investigate elongated growth within biological tissues by describing the evolution over time of the shape of a fruit fly's wing. They found the aspect ratio of the typical biological shapes may exhibit a maximum at finite time and then decrease. The findings have been published in EPJ E.

Chemical sensor on a chip
Scientists at the Vienna University of Technology have managed to create a tiny laser and a corresponding light detector in one production process, on a single chip. The light is transported from the laser to the detector on a specially designed waveguide. That way, the chip can measure the chemical composition of the liquid in which it is submerged.

DNA-linked nanoparticles form switchable 'thin films' on a liquid surface
Scientists have used DNA-linked nanoparticles to form a single-particle-thick layer on a liquid surface where the properties of the layer can be easily switched. Understanding the assembly of such nanostructured thin films provides a possible pathway to adjustable filters, surfaces with variable mechanical response, or even new ways to deliver genes for biomedical applications.

Technology using microwave heating may impact electronics manufacture
Engineers have successfully shown that a continuous flow reactor can produce high-quality nanoparticles by using microwave-assisted heating -- essentially the same forces that heat up leftover food with such efficiency. This may finally make it possible for this technology to move into large scale manufacturing and usher in an electronics revolution.

University of Pennsylvania researchers have shown that a certain kind of dendrimer, a molecule that features tree-like branches, offers a simple way of creating vesicles and tailoring their diameter and thickness. Moreover, these dendrimer-based vesicles self-assemble with concentric layers of membranes, much like an onion.

Princeton Plasma Lab funded to explore nanoparticles with plasma
The US Department of Energy's Princeton Plasma Physics Laboratory has received some $4.3 million of DOE Office of Science funding, over three years, to develop an increased understanding of the role of plasma in the synthesis of nanoparticles. Such particles, which are measured in billionths of a meter, are prized for their use in everything from golf clubs and swimwear to microchips, paints and pharmaceutical products. They also have potentially wide-ranging applications in the development of new energy technologies.

New class of nanoparticle brings cheaper, lighter solar cells outdoors
Researchers in the University of Toronto's Edward S. Rogers Sr. Department of Electrical & Computer Engineering have designed and tested a new class of solar-sensitive nanoparticle that outshines the current state of the art employing this new class of technology. This new form of solid, stable light-sensitive nanoparticles, called colloidal quantum dots, could lead to cheaper and more flexible solar cells, as well as better gas sensors, infrared lasers, infrared light emitting diodes and more.
