When most people tackle DIY projects related to airports, it’s usually some kind of over-the-top commercial airline simulator. But not Ben Krasnow He took a decidedly different approach by building his own X-ray backscatter machine using various parts found on eBay. More »

The US Department of Energy’s SLAC accelerator lab already has a pretty useful X-ray laser — the Linac Coherent Light Source (LCLS). But, recent modifications to the device have scientists drooling over its new found potential. Using a thin wafer of diamond, the Stanford-run lab filtered the beam to a lone frequency, then amplified it in a process called “self-seeding.” That’s given the world’s most powerful X-ray laser even more punch by tossing out unneeded wavelengths which were reducing its intensity. The tweaks allow scientists across many fields to finesse and image matter at the atomic level, giving them more power to study and change it. According to the lab, researchers who came to observe the experiment from other X-ray laser facilities “were grinning from ear to ear” at the possibility of integrating the tech into their own labs. The SLAC team claims they could still add 10 times more punch to the LCLS with further optimization, putting the laser in a class by itself — X-ray-wise, anyway.

Much ado has been made of weather-resistant cameras, but it’s all a moot point if the memory card dies, isn’t it? Panasonic wants that level of survivability in its SDHC and SDXC cards, and its new UHS-I-level SDAB and SDUB lines are tested for the kind of abuse that could see the camera give up the ghost first. The cards can take the kinds of punishment that we often associate with rugged gear, such as temperatures from -13F to 185F, immersion in 3.3 feet of water for half an hour and the usual steep drops. It’s beyond this that the resistance levels become truly exotic: the cards are also built to survive zaps of electricity, proximity to magnets and exposure to X-rays. If it all becomes too much to bear, the design will even fuse on the inside to prevent fire burning the card from within. Those who like what they see will only have to decide whether or not they want the SDAB range’s 95MB/s read speeds and 80MB/s writes or are willing to settle for the SDUB line’s respective 90MB/s and 45MB/s transfers. We have yet to see if or when the SD cards cross the Pacific after their September 8th launch in Japan, although we hope so — with that kind of extra-tough design, our photos are more likely to endure than we will.

A very small atom can cast a very large shadow. Well, not literally, but figuratively. Researchers at Griffith University have managed to snap the first image of a single atom’s shadow and, while the dark spot may be physically small, the implications for the field of quantum computing are huge. The team of scientists blasted a Ytterbium atom suspended in air with a laser beam. Using a Fresnel lens, they were able to snap a photograph of the dark spot left in the atom’s wake as the laser passed over it. The practical applications could improve the efficiency of quantum computers, where light is often used to transfer information. Since atoms have well understood light absorption properties, predictions can be made about the depth of a shadow cast, improving communication between the individual atoms performing calculations. The research could even be applied to seemingly mundane and established fields like X-Ray imaging, by enabling us to find the proper intensity levels to produce a quality image while minimizing damage to cells. For more info, check out the current issue of Nature.

It was Bret Easton Ellis who coined the phrase, “The better you look, the more you see,” and it appears the folks down at NASA’s Jet Propulsion Lab agree. In what’s considered a “first,” the agency’s latest space-scouring probe, the Nuclear Spectroscopic Telescope Array, has turned on its X-ray vision to capture focused images of a black hole, dubbed Cygnus X-1, feeding on a nearby giant star. By tuning into these high-energy frequencies, scientists are getting a peak into a previously unseen side of the heavens at 100 times the sensitivity and 10 times the resolution of any preceding tech. The space agency plans to use the observatory’s powerful sight to suss out other known areas of mass X-ray activity like 3C273, an active quasar located two billion light years away and even explore G21.5-0.9, the fallout from a supernova within the Milky Way galaxy. NuSTAR’s first tour of galactic duty will span two year’s time, during which it’ll attempt to record imagery from “the most energetic objects in the universe, ” as well as track the existence of black holes throughout the cosmos. Impressed? Yeah, us too.
