SLAC scientists invent a way to see attosecond electron motions with an X-ray laser

Called XLEAP, the new method will provide sharp views of electrons in chemical processes that take place in billionths of a billionth of a second and drive crucial aspects of life.

Menlo Park, Calif. — Researchers at the Department of Energy’s SLAC National Accelerator Laboratory have invented a way to observe the movements of electrons with powerful X-ray laser bursts just 280 attoseconds, or billionths of a billionth of a second, long.

A SLAC-led team has invented a method, called XLEAP, that generates powerful low-energy X-ray laser pulses that are only 280 attoseconds, or billionths of a billionth of a second, long and that can reveal for the first time the fastest motions of electrons that drive chemistry. This illustration shows how the scientists use a series of magnets to transform an electron bunch (blue shape at left) at SLAC’s Linac Coherent Light Source into a narrow current spike (blue shape at right), which then produces a very intense attosecond X-ray flash (yellow).

The technology, called X-ray laser-enhanced attosecond pulse generation (XLEAP), is a big advance that scientists have been working toward for years, and it paves the way for breakthrough studies of how electrons speeding around molecules initiate crucial processes in biology, chemistry, materials science and more.

CERN chip enables first 3D color X-ray images of the human body

IMG_7849

Using CERN technology, Mars Bioimaging has created the first 3D, color X-ray images of the human body.

Medical X-ray scans have long been stuck in the black-and-white, silent-movie era. Sure, the contrast helps doctors spot breaks and fractures in bones, but more detail could help pinpoint other problems. Now, a company from New Zealand has developed a bioimaging scanner that can produce full color, three dimensional images of bones, lipids, and soft tissue, thanks to a sensor chip developed at CERN for use in the Large Hadron Collider.

Mars Bioimaging, the company behind the new scanner, describes the leap as similar to that of black-and-white to color photography. In traditional CT scans, X-rays are beamed through tissue and their intensity is measured on the other side. Since denser materials like bone attenuate (weaken the energy) of X-rays more than soft tissue does, their shape becomes clear as a flat, monochrome image.

Airport full-body X-ray scanners banned across Europe as unsafe

TSA_mmw_large-580x335

“Safety” at a price.

Ever since the attack on the Twin Towers back in 2001, security at airports has been significantly increased to help ensure no aircraft is ever hijacked again. But some of the new security measures have not been welcomed by all, with the prime example being the new full-body X-ray scanners.

These scanners are controversial for two reasons. The first is that they allow operators to see an intimate, graphic view of the person being scanned. But that has been solved to a large extent by the use of privacy filters.

The second, and much larger concern is the risk of them causing cancer…

Annual chest x-rays fail to reduce death rate from lung cancer

chest xray

Best strategy for discovering lung tumors are the more costly CT scans.

Chest X-rays done annually didn’t significantly reduce the death rate from lung cancer in a study involving more than 150,000 patients that reflects the challenges of using early detection to save lives in the battle against malignancies.

Using a custom-built camera the size of a refrigerator, Florida researchers have made the world s first crude pictures of X-rays streaming from a stroke of lightning

It might look like an homage to the iconic 80s gameshow Blockbusters hosted by Bob Holness.  But this crude image is actually the world’s first picture of X-rays streaming from a bolt of lightning.

X-Ray Glasses Are Here

For all those closet peeping toms out there

Remember those ads in the back of comic books with the crazy X-ray glasses? You know… they had plastic frames and cardboard eye-covers with holes in them (presumably so you wouldn’t face-plant while walking); and the cardboard had these wild spirals on them…

And they never worked. Ever. How many of us were suckered in by the lure of seeing through a girl’s shirt? Not that we really would’ve known what we were looking at, but still… it was taboo. And so we bought these pieces of trash and… nothing. Very disappointing.

Until now. Continue reading… “X-Ray Glasses Are Here”

Incubators Made Out Of Car Parts To Curb Infant Mortality In Developing Countries

Incubators Made Out Of Car Parts To Curb Infant Mortality In Developing Countries 

The heat source is a pair of headlights. A car door alarm signals emergencies. An auto air filter and fan provide climate control. But this contraption has nothing to do with transportation. It is a sturdy, low-cost incubator, designed to keep vulnerable newborns warm during the first fragile days of life.
