Nature Physics
Ultrafast heat conduction can manipulate nanoscale magnets
Researchers at the University of Illinois at Urbana-Champaign have uncovered physical mechanisms allowing the manipulation of magnetic information with heat. These new phenomena rely on the transport of thermal energy, in contrast to the conventional application of magnetic fields, providing a new, and highly desirable way to manipulate magnetization at the nanoscale.

Futuristic components on silicon chips, fabricated successfully
A team of IBM researchers in Zurich, Switzerland with support from colleagues in Yorktown Heights, N.Y., has developed a relatively simple, robust and versatile process for growing crystals made from compound semiconductor materials that will allow them be integrated onto silicon wafers -- an important step toward making future computer chips that will allow integrated circuits to continue shrinking in size and cost even as they increase in performance.

Injectable electronics
A team of international researchers, led by Charles Lieber, the Mark Hyman, Jr. Professor of Chemistry, an international team of researchers developed a method for fabricating nano-scale electronic scaffolds that can be injected via syringe. Once connected to electronic devices, the scaffolds can be used to monitor neural activity, stimulate tissues and even promote regenerations of neurons.

New survey: Only about half of men can remember their last medical check-up
A new national survey by Orlando Health found that more than 80 percent of men could remember the make and model of their first car, but only about half could remember their last check up with a doctor. Hoping to change that, two doctors will embark on a nine-day, 6,000 mile drive from Clermont, Fla., to New York to Los Angeles in an all-electric Tesla, urging men to make their health a priority.

Next-generation illumination using silicon quantum dot-based white-blue LED
An Si quantum dot (QD)-based hybrid inorganic/organic light-emitting diode (LED) that exhibits white-blue electroluminescence has been fabricated by Professor Ken-ichi Saitow, graduate student Yunzi Xin, and their collaborators. A hybrid LED is expected to be a next-generation illumination device for producing flexible lighting and display, and this is achieved for the Si QD-based white-blue LED.

Penn engineers show how 'perfect' materials begin to fail
Until recently, making a defect-free material was impossible. Now that nanotechnological advances have made such materials a reality, however, researchers at the University of Pennsylvania and Germany's Max Planck Institute for Intelligent Systems have shown how these defects first form on the road to failure.

Vanishing friction
Physicists at MIT have developed an experimental technique to simulate friction at the nanoscale. Using their technique, the researchers are able to directly observe individual atoms at the interface of two surfaces and manipulate their arrangement, tuning the amount of friction between the surfaces. By changing the spacing of atoms on one surface, they observed a point at which friction disappears.

Montreal researchers develop ultra-tough fiber that imitates the structure of spider silk
Professors Frederick Gosselin and Daniel Therriault, along with their master's student Renaud Passieux, are not related to Spiderman. Nevertheless, these Polytechnique Montreal researchers have produced an ultra-tough polymer fiber directly inspired by spider silk! They recently published an article about the project in the journal Advanced Materials.

How natural channel proteins move in artificial membranes
Natural channel proteins are integrated into artificial membranes to facilitate the transport of ions and molecules. Researchers at the University of Basel have now been able to measure the movement of these channel proteins for the first time. They move up to ten times slower than in their natural environment, namely the cell membrane. As reported in academic journal 'Nano Letters', the results may prove useful to the ongoing development of new applications such as nanoreactors and artificial organelles.

Researchers simulate behavior of 'active matter'
From flocks of starlings to schools of fish, nature is full of intricate dynamics that emerge from the collective behavior of individuals. In recent years, interest has grown in trying to capture similar dynamics to make self-assembling materials from so-called 'active matter.' Researchers from Brown University have shed new light on the dynamics of one type of active matter known as active colloids.

Measuring the mass of molecules on the nano-scale
Working with a device that slightly resembles a microscopically tiny tuning fork, researchers at the University of Tsukuba in Japan have recently developed coupled microcantilevers that can make mass measurements on the order of nanograms with only a 1 percent margin of error -- potentially enabling the weighing of individual molecules in liquid environments. The findings are published this week in Applied Physics Letters.
