Science Daily explores the weird, microscopic world of
making ceramics that can bend and twist and smush and reform:

Caltech materials scientist Julia Greer and her colleagues…explain how they used the method to produce a ceramic (e.g., a piece of chalk or a brick) that contains about 99.9 percent air yet is incredibly strong, and [...]

Nature is sharing a fun little recipe for whipping up the super-material graphene in a kitchen blender:

In Nature Materials, a team led by [Jonathan] Coleman [at Trinity College, Dublin,] (and funded by the UK-based firm Thomas Swan) describe how they took a high-power (400-watt) kitchen blender and added half a litre of water, [...]

Or: “Weird substance gets weirder.” Nature has more on how the latest tests have thrown models of how carbon circuits are supposed to work into disarray:

In graphene, electrons can move faster than in any other material at room temperature. But techniques that cut sheets of graphene into the narrow ribbons needed to form [...]

Remember the superhero fashion designer in The Incredibles? Nature unfolds the true story of a “super-material” that repels liquids so well, it resists molten metal:

Kripa Varanasi, a mechanical engineer at the Massachusetts Institute of Technology in Cambridge, and his colleagues used a water-repellent material which they further engineered by adding tiny ridges 0.1 [...]

We’re getting closer to having hologram projectors in our pockets, as befits people living in the future. PhysOrg reports on the latest step – a system that converts mobile-device displays into three-dimensional images:

Launched earlier this year, EyeFly3D, the first glasses-free 3D accessory for smartphones, has just picked up its first award from IES. [...]

Science Art: <i>Fulleride Cs3C60</i> by Dmitri Zaitsev and Joffe Ilya Naftolevich

This is a buckyball crystal, a form of carbon that no one had ever seen until the 1980s. Now, it’s starting to get used in all kinds of unexpected ways. Formally, this stuff is is known as Carbon-60 or buckminsterfullerene, because the molecule looks so much like a geodesic dome as envisioned by [...]

Wired reveals the weird ways nanotechnologists are making sound behave like light… this time, by creating a Star Trek weapon in the lab:

Because laser is an acronym for “light amplification by stimulated emission of radiation,” these new contraptions – which exploit particles of sound called phonons – should properly be called phasers. Such [...]

The Economist is gazing into the pretty colors…not of quantum computers, but quantum television screens:

An LCD screen works with a backlight shining through red, blue or green filters to produce the pixels which make up an image. Many televisions use light-emitting diodes (LEDs) as the backlight because they are brighter and use less power [...]
