Cell
Another beautiful helix for biology, this time reminiscent of a parking garage
The endoplasmic reticulum is the protein-making factory within cells consisting of tightly stacked sheets of membrane studded with the molecules that make proteins. Now, researchers have refined a new microscopy imaging method to visualize exactly how the ER sheets are stacked, revealing that the 3D structure of the sheets resembles a parking garage. This structure allows for the dense packing of ER sheets, maximizing the amount of space available for protein synthesis.

Ironing out the origins of wrinkles, creases and folds
Engineers from Brown University have mapped out the amounts of compression required to cause wrinkles, creases, and folds to form in rubbery materials. The findings could help engineers control the formation of these structures, which can be useful in designing nanostructured materials for flexible electronic devices or surfaces that require variable adhesion.

Molecular Therapy
Nano drug crosses blood-brain tumor barrier, targets brain-tumor cells and blood vessels
The blood-brain barrier protects the brain from poisons but also prevents drugs from reaching brain tumors. A preclinical study shows that an experimental nanotechnology drug called SapC-DOPS crosses the tumor blood-brain barrier, targets brain-tumor cells and retards growth of tumor blood vessels. The findings also show why the agent targets tumor cells and recommend the drug's further development as a novel treatment for glioblastoma.

A heart of gold
Dr. Tal Dvir of Tel Aviv University has integrated cardiac cells with nanofibers made of real gold particles to create functional engineered cardiac tissues. With the gold particles, these tissues contract much faster and stronger as a whole, he reports, making them more viable for transplants and post-heart-attack therapies.

Deciphering butterflies' designer colors: Findings could inspire new hue-changing materials
A team of researchers in Hong Kong has uncovered how subtle differences in the tiny crystals of butterfly wings create stunningly varied patterns of color even among closely related species. The discovery, reported today in the Optical Society's open-access journal Optical Materials Express, could lead to new coatings for manufactured materials that could change color by design, if researchers can figure out how to replicate the wings' light-manipulating properties.

Researchers step closer to custom-building new blood vessels
Researchers at Johns Hopkins have coaxed stem cells into forming networks of new blood vessels in the laboratory, then successfully transplanted them into mice. The stem cells are made by reprogramming ordinary cells, so the new technique could potentially be used to make blood vessels genetically matched to individual patients and unlikely to be rejected by their immune systems, the investigators say.

Using pressure to swell pores, not crush them
High pressure doesn't crush zeolites -- it actually makes interior nanopores expand. Researchers show how "super-hydration" inserts more water molecules into the cavities than can fit under ambient conditions.

Air Force support for a new generation of lithium-ion batteries
Four years ago, a Rice University research team demonstrated that they could chemically unzip cylindrical shaped carbon nanotubes into soluble graphene nanoribbons (GNR) without compromising the electronic properties of the graphitic structure. A recent paper by the team, published in IEEE Spectrum and partially funded by AFOSR, showed that GNR can significantly increase the storage capacity of lithium ion by combining graphene nanoribbons with tin oxide.

NIST shows how to make a compact frequency comb in minutes
Laser frequency combs -- high-precision tools for measuring different colors of light in an ever-growing range of applications -- are not only getting smaller but also much easier to make. NIST physicists can now make the core of a miniature frequency comb in one minute. Conventional microfabrication techniques, by contrast, may require hours, days or even weeks.

Jagged graphene edges can slice into cell membranes
Researchers from Brown University have shown how tiny graphene sheets can be big trouble for cells. Sharp corners and jagged edges on the sheets puncture cell membranes, allowing the sheet to enter the cell and disrupt function. The new understanding of how graphene interacts with cells could lead to safer production of this important nanomaterial.

Heat radiation of small objects: Beyond Planck's equations
In 1900, Max Planck came up with his famous equation, describing heat radiation of stars or glowing metal - but it is not applicable for very small objects. Physicists in Vienna have studied the heat radiation of ultra thin glass fibers. Their findings can be explained by the more general theory of fluctuational electrodynamics. Understanding heat radiation of small objects is important for nanotechnology, and also for climate predictions.
