Today is the 15th anniversary of the launch of the Chandra X-ray Observatory. Chandra is one of NASA's "Great Observatories," along with the Hubble Space Telescope and Spitzer Space Telescope. Since its launch, its x-ray vision and high sensitivity have helped us to better understand the universe.  Read More

As the US prepares for 4th of July fireworks here on Earth, a nearby spiral galaxy similar to our Milky Way is putting on a pyrotechnics display of its own. The galaxy, NGC 4258 (also known as Messier 106 or M 106), is ejecting gas and high-energy particles in a spectacular display of power that is rippling across the face of the galaxy with shock waves of stellar energy.  Read More

A group of researchers at New Jersey-based LPP Fusion is turning to crowdfunding to demonstrate net power gain from a nuclear fusion reactor. The scientists plan to do this using a technique which is relatively little-known, but which they claim is scientifically sound and only relies on well-established science. Given enough funding, the researchers say they could design a US$500,000, 5 MW reactor that would produce energy for as little as 0.06 cents per kWh, all by the end of the decade.  Read More

Recent data captured by NASA's Chandra Observatory and Spitzer Space Telescope has cast doubt on the basic model that accounts for the creation of star clusters. The data, collected from studies of NGC 2024, located in the Flame Nebula and the Orion Nebula Cluster, will require scientists to think up an entirely new approach as to how these celestial bodies come into creation.  Read More

Using X-rays and other forms of radiation has been a standard tool for testing pipelines for decades, but until now it's been largely confined to factories and land-based pipelines instead of the deep seabed. That’s changing as GE adapts its medical X-ray systems to work in the crushing pressures of the deep oceans, as part of a remote-controlled submersible rig for examining pipelines in place.  Read More

The newly detected radioactive elements of Cas A glow blue in this composite image (Image:...

NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) is unraveling the mystery of how stars go supernova by mapping the remnants of radioactive material left in the wake of a supernova. The findings go against previous theories to create a more chaotic view of the conditions prevailing directly before a star explodes.  Read More

The design of the automated filleting machine developed by the APRICOT project

Manual filleting of fish can be a time-consuming task. Due to higher salaries in Nordic countries, processing of fish caught there is often carried out in places like Asia, Eastern Europe and Russia where labor costs are lower, before the fish is returned to Scandinavia for sale. The APRICOT (Automated Pinbone Removal In Cod and WhiTefish) project set out in January, 2012 to find an automated solution that would keep fish processing local and it has now developed a machine that achieves just that.  Read More

An X-ray of a human wrist demonstrates the system's ability to reveal soft-tissue structur...

X-ray machines are all large devices that can only image hard structures such as bone, unless a contrast-enhancing solution such as barium is present in the patient ... right? Well, no, not all of them. A new system developed by researchers at MIT and Massachusetts General Hospital is small enough to be considered portable, doesn't expose patients to as much radiation, and can image soft tissues in minute detail.  Read More

Eucalyptus leaves showing traces of different minerals including gold

Scientists from Australia's Commonwealth Scientific and Industrial Research Organisation have discovered that eucalyptus trees in the Australian outback are drawing up gold particles from deep underground through their root system and depositing the precious metal in their leaves and branches. Rather than being a new source of "gold leaf," the discovery could provide a cheaper, more environmentally friendly way to uncover valuable gold ore deposits.  Read More

X-rays can be used to detect pieces of gold somewhat smaller than this monster

Every year, Australian mining companies discard hundred of millions of dollars worth of gold. They're not doing it on purpose, it’s just that the standard industry technique of scanning mineral samples isn’t sensitive enough to detect small traces of the precious metal. Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) and Canadian company Mevex have tested a new technique using powerful X-rays that can detect these small trace amounts quickly and accurately.  Read More
