[Technical Comment] Comment on “Crystal structures of translocator protein (TSPO) and mutant mimic of a human polymorphism”

Science: Current Issue
Li et al. (Reports, 30 January, p. 555) reported on a crystal structure for a translocator protein (TSPO) from Rhodobacter sphaeroides in which some of the electron density is modeled as a porphyrin. The analysis of the x-ray data discussed here suggests that this assignment is incorrect. Author: Jimin Wang

Yu Founder On Next Flagship and Open Source Model for Upcoming Smartphones

Image
Micromax subsidiary Yu Televentures is gearing up to launch its next flagship smartphone this month. Ahead of the launch, company founder Rahul Sharma spoke to Gadgets 360 about the company's strategy for upcoming smartphones and the relationship with Cyanogen. He confirmed that the upcoming Yu flagship will run Android with some customisations from the company, and not Cyanogen , as seen on its predecessor. Sharma revealed that the company has so far sold 2 million devices since Yu established itself as an independent brand, with a new flagship smartphone expected to launch later this month. Talking about the upcoming smartphone, Sharma said that the company will be focusing on offering "pure Android experience" with a deep integration of Around Yu , a service aggregator platform that was introduced last year alongside the Yutopia flagship. He further hinted that the Around Yu will come with some new features. "When we got Cyanogen things were moving fine but ...

The Elephant's Trunk in IC 1396

Image
Like an illustration in a galactic Just So Story, the Elephant's Trunk Nebula winds through the emission nebula and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Of course, the cosmic elephant's trunk is over 20 light-years long. This composite was recorded through narrow band filters that transmit the light from ionized hydrogen, sulfur, and oxygen atoms in the region. The resulting image highlights the bright swept-back ridges that outline pockets of cool interstellar dust and gas. Such embedded, dark, tendril-shaped clouds contain the raw material for star formation and hide protostars within the obscuring cosmic dust. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a large region on the sky, spanning over 5 degrees.

La Palma Eclipse Sequence

Image
At left, a dramatic image sequence follows late September's total lunar eclipse above a rugged landscape and sea of clouds from the Canary island of La Palma. Composited in a circular fisheye projection, the brightness of the Full Perigee Moon changes drastically in transition from outside the total eclipse phase compared to its dim glow during the 72 minute long totality. At right, a single frame captures the dark red lunar disk in a moment during the total eclipse phase, the Moon deep within Earth's shadow. In fact, the size of the eclipsed Moon image at right approximately illustrates the relative size of Earth and Moon, when compared to the circular projection of the eclipse sequence.
