In medicine, X-rays provide high-resolution images of our insides to help doctors make a definitive diagnosis. Industry uses X-rays, too - as a reliable, non-destructive way of seeing what's hidden on inside materials and components and to check for cracks or irregularities. However industry additionally draws upon different technologies that are not used in the medical field. Whereas medical X-ray machines have been specifically designed for human test subjects, industrial X-ray machines are used to analyze objects that vary much more in their size and material composition.

Tropical Cyclone Bakung is moving in a westerly direction over the open waters of the Southern Indian Ocean and NASA's Aqua satellite captured an image of the sea storm.
Extreme climate and weather events such as record high temperatures, intense downpours and severe storm surges are becoming more common in many parts of the world. But because high-quality weather records go back only about 100 years, most scientists have been reluctant to say if global warming affected particular extreme events.
New research published today in the journal Physical Review Letters describes how recreating isotopes that occur when a star explodes, can help physicists understand where life-supporting elements may be found in space.
A study looking at Jamie's Ministry of Food Australia 10-week program has found that it brings not only a change in attitudes but also in behavior when buying healthy food. The research published in the open access journal BMC Public Health has found that these changes continue up to six months after completion of the program.
WEST LAFAYETTE, Ind. - A new method that creates large-area patterns of three-dimensional nanoshapes from metal sheets represents a potential manufacturing system to inexpensively mass produce innovations such as "plasmonic metamaterials" for advanced technologies.
The metamaterials have engineered surfaces that contain features, patterns or elements on the scale of nanometers that enable unprecedented control of light and could bring innovations such as high-speed electronics, advanced sensors and solar cells.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) may have detected the dusty hallmarks of an entire family of Pluto-size objects swarming around an adolescent version of our own Sun.

Origami is capable of turning a simple sheet of paper into a pretty paper crane, but the principles behind the paper-folding art can also be applied to making a microfluidic device for a blood test, or for storing a satellite's solar panel in a rocket's cargo bay.
A team of University of Pennsylvania researchers is turning kirigami, a related art form that allows the paper to be cut, into a technique that can be applied equally to structures on those vastly divergent length scales.
An interstellar mystery of why stars form has been solved thanks to the most realistic supercomputer simulations of galaxies yet made.
Theoretical astrophysicist Philip Hopkins of the California Institute of Technology (CalTech) led research that found that stellar activity -- like supernova explosions or even just starlight -- plays a big part in the formation of other stars and the growth of galaxies.
The once mighty super typhoon has weakened to a depression in the South China Sea as it heads for a final landfall in southern Vietnam. NASA's Aqua satellite captured an image of the storm that showed it was weakening.
NASA's Aqua satellite passed over Hagupit on Dec. 11 at 05:20 UTC (12:20 a.m. EST) and the MODIS instrument captured a visible image of the storm. The MODIS image showed that the thunderstorms had become fragmented around the circulation center.
San Antonio -- December 11, 2014 -- Southwest Research Institute (SwRI) is preparing to unveil a new, miniature portable solar observatory for use onboard a commercial, manned suborbital spacecraft. The SwRI Solar Instrument Pointing Platform (SSIPP) will be on exhibit at the fall meeting of the American Geophysical Union (AGU), Dec. 16-19, at the Moscone Center in San Francisco, Calif.
DARIEN, IL - A new study shows that paid work time is the primary waking activity exchanged for sleep and suggests that chronic sleep loss potentially could be prevented by strategies that make work start times more flexible.
Could there finally be tangible evidence for the existence of dark matter in the Universe? After sifting through reams of X-ray data, scientists in EPFL's Laboratory of Particle Physics and Cosmology (LPPC) and Leiden University believe they could have identified the signal of a particle of dark matter. This substance, which up to now has been purely hypothetical, is run by none of the standard models of physics other than through the gravitational force. Their research will be published next week in Physical Review Letters.
A 13-year decline in vegetation in the eastern and southeastern Amazon has been linked to a decade-long rainfall decline in the region, a new NASA-funded study finds.
With global climate models projecting further drying over the Amazon in the future, the potential loss of vegetation and the associated loss of carbon storage may speed up global climate change.
