$8.5 million grant for developing nano printing technology
Northwestern University has received a five-year, $8.5 million grant from the US Department of Defense's competitive Multidisciplinary University Research Initiative program to develop a '4-dimensional printer' -- the next generation of printing technology for the scientific world. Once developed, the 4-D printer, operating on the nanoscale, will be used to construct new devices for research in chemistry, materials sciences and US defense-related areas that could lead to new chemical and biological sensors, catalysts, microchip designs and more.

A protein provides emergency aid
Small heat shock proteins ensure that other proteins do not clot, allowing the cell to survive stress. Defects in these 'small helpers' are associated with medical conditions like cataracts and cancer. Now, scientists at the Technische Universität München have characterized a small heat shock protein responsible for embryonic development in the Caenorhabditis elegans nematode. Presumably, a similar protein exists also in humans.

Framework materials yield to pressure
High pressure has become an indispensable research tool in the quest for novel functional materials. High-pressure crystallographic studies on non-porous framework materials based on coordination compounds are markedly on the rise, enabling the unraveling of structural phenomena and taking us a step closer to the derivation of structure-property relationships.

Strong teeth: Nanostructures under stress make teeth crack resistant
Human teeth have to serve for a lifetime, despite being subjected to huge forces. But the high failure resistance of dentin in teeth is not fully understood. An interdisciplinary team led by scientists of Charite Universitaetsmedizin Berlin has now analyzed the complex structure of dentin. At the synchrotron sources BESSY II at HZB, Berlin, Germany, and the European Synchrotron Radiation Facility ESRF, Grenoble, France, they could reveal that the mineral particles are precompressed.

NIST's 'nano-raspberries' could bear fruit in fuel cells
Researchers at the National Institute of Standards and Technology (NIST) have developed a fast, simple process for making platinum 'nano-raspberries' -- microscopic clusters of nanoscale particles of the precious metal. The berry-like shape is significant because it has a high surface area, which is helpful in the design of catalysts. Even better news for industrial chemists: the researchers figured out when and why the berry clusters clump into larger bunches of 'nano-grapes.'

MIPT physicists develop ultrasensitive nanomechanical biosensor
Two young researchers working at the MIPT Laboratory of Nanooptics and Plasmonics, Dmitry Fedyanin and Yury Stebunov, have developed an ultracompact highly sensitive nanomechanical sensor for analyzing the chemical composition of substances and detecting biological objects, such as viral disease markers, which appear when the immune system responds to incurable or hard-to-cure diseases, including HIV, hepatitis, herpes, and many others. The sensor will enable doctors to identify tumor markers, whose presence in the body signals the emergence and growth of cancerous tumors.

A step towards a type 1 diabetes vaccine by using nanotherapy
For the first time liposomes that imitate cells in the process of natural death have been used to treat diabetes. Researchers at Germans Trias Research Institute generated liposomes in collaboration with professionals from the ICN2. PLOS ONE Journal publishes the work. The next steps are to confirm the efficacy in vivo with cells from patients and to carry out clinical trials to prevent the disease and to cure it.

Filming the film: Scientists observe photographic exposure live at the nanoscale
Photoinduced chemical reactions are responsible for many fundamental processes and technologies, from energy conversion in nature to micro fabrication by photo-lithography. Scientists have now monitored the chemical processes during a photographic exposure at the level of individual nanoscale grains in real-time. The research team lead by Professor Jianwei (John) Miao from the University of California in Los Angeles and Prof. Tim Salditt from the University of Göttingen report their work in the journal Nature Materials.

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.

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.

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.
