Researchers have produced the first atomically thin 2-D sheets of organic-inorganic hybrid perovskites. These ionic materials exhibit optical properties not found in 2-D covalent semiconductors such as graphene, making them promising alternatives to silicon for future electronic devices.

Scale-free urination and speed bump diagnostics take home Ig Nobels
Science Focus
original post »
(credit: Improbable Research)
Every fall, the Swedish Academy of Sciences determines which researchers have produced work worthy of a Nobel Prize. Usually, my first warning that this time of the year is approaching is the announcement of the Ig Nobel Prizes, handed out in Boston "for achievements that first make people laugh, then make them think."
The Nobels must be coming soon, as the Igs were handed out last night in a traditionally lavish and mildly deranged ceremony. As is typical, almost all of the winning research teams had a representative present. One of the two exceptions sent a video acceptance; the only group that did not acknowledge its win was the Bangkok Metropolitan Police Force. We'll go through the awards below, starting with the ones that are also awarded science Nobels, and then moving into some of the more flexible categories before wrapping up with Economics and Literature.
Physics: The fluid mechanics of urination. The team that won this award was interested in what they call "a universal phenomenon that has received little attention"—the physics of urination. To get a sense of how urination operates on different scales, the researchers hauled a video camera to Zoo Atlanta and filmed animals relieving themselves. "Our findings reveal that the urethra is a flow-enhancing device," they concluded, "enabling the urinary system to be scaled up by a factor of 3,600 in volume without compromising its function."

'Fossils' of galaxies reveal the formation and evolution of massive galaxies
more »
Astronomers have observed massive dead galaxies in the universe 4 billion years after the Big Bang. They discovered that the stellar content of these galaxies is strikingly similar to that of massive elliptical galaxies seen locally. Furthermore, they identified progenitors of these dead galaxies when they were forming stars at an earlier cosmic epoch, unveiling the formation and evolution of massive galaxies across 11 billion years of cosmic time.

Trifid Nebula, Messier 16 Rectangular Sticker
Here's a great sheet of stickers featuring a beautiful image from deep space
tagged with: breathtaking astronomy images, star forming nebulae, trfdnbl, star nurseries, galaxies, nebulae, star factory, trifid nebula, star clusters, heavens, factories for stars, eso, vista, european southern observatory
Galaxies, Stars and Nebulae series A fantastic picture from our universe featuring the massive star factory known as the Trifid Nebula.
It was captured in all its glory with the Wide-Field Imager camera attached to the MPG/ESO 2.2-metre telescope at ESO's La Silla Observatory in northern Chile.
So named for the dark dust bands that trisect its glowing heart, the Trifid Nebula is a rare combination of three nebulae types that reveal the fury of freshly formed stars and point to more star birth in the future. The field of view of the image is approximately 13 x 17 arcminutes.
It's an awe-inspiring, breathtaking image that reveals some of the wonder that is our universe.

Pluto's Snakeskin Terrain
more »
A mountainous region informally known as Tartarus Dorsa sprawls some 530 kilometers (330 miles) across this Plutonian landscape. Recently downloaded from New Horizons, it combines blue, red, and infrared image data in an extended color view captured near the spacecraft's close approach to Pluto on July 14. Shadows near the terminator, the line between Pluto's dim day and night, emphasize a rough, scaly texture. The stunning image resolves details on the distant world about 1.3 kilometers (0.8 miles) across. Refering to a part of Hades in ancient Greek mythology, Tartarus Dorsa borders Tombaugh Regio to the east.

Horsehead Nebula - Our Awesome Universe Wall Graphics
Here's a great wall decal featuring a beautiful image from deep space
tagged with: breathtaking astronomy images, hrshdneb, stars, nebulae, star clusters, starfields, star nurseries, horsehead nebula, galaxies, vista, european southern observatory, eso
Galaxies, Stars and Nebulae series A gorgeous deep space photograph featuring the Horsehead Nebula.
It's actually a composite colour image based on three exposures in the visual part of the spectrum with the FORS2 multi-mode instrument at the 8.2-m KUEYEN telescope at Paranal.
It was produced from three images, obtained on February 1, 2000, with the FORS2 multi-mode instrument at the 8.2-m KUEYEN Unit Telescope and extracted from the VLT Science Archive Facility.
The frames were obtained in the B-band (600 sec exposure; wavelength 429 nm; FWHM 88 nm; here rendered as blue), V-band (300 sec; 554 nm; 112 nm; green) and R-band (120 sec; 655 nm; 165 nm; red).
The original pixel size is 0.2 arcsec.

Cats Eye Nebula Square Sticker
Here's a great sheet of stickers featuring a beautiful image from deep space
tagged with: nebulae, amazing astronomy images, tcenebnch, hubble chandra images, cats eye nebula, stellar evolution, dying star, red giant evolution, galaxies, outer space pictures, stars, nasa
Galaxies, Stars and Nebulae series A gorgeous design featuring a composite image of the Cat's Eye nebula from NASA's Chandra X-ray Observatory and the Hubble Space Telescope.
This famous nebula represents a phase of stellar evolution after a star like our Sun runs out of fuel. In this phase, a star becomes an expanding red giant and sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures.
