The majority of the universe is made up of mysterious, practically invisible dark matter. But new research is beginning to help us understand it, and seems to indicate that it could be even "darker" than previously thought.  Read More

Supermassive black holes are titanic oddities. Usually sited at the core of galaxies and various high-energy phenomena such as quasars, their mass can be anywhere from that of a hundred thousand to billions of suns. Now observations from NASA and ESA space telescopes are shedding light on the incredibly powerful cosmic winds they produce, which can have more energy than an entire galaxy.  Read More

Scientists are studying vintage violins, to find out what features give them their distinc...

A team of MIT acousticians and fluid dynamicists have teamed up with Bostonian violin makers to meticulously analyze hundreds of instruments from the Cremonese period, considered the golden age of violin making. The findings not only reveal key design features, but also shed light on whether the development of the instruments was deliberate, or simply a product of human error.  Read More

The minute particles seen in this microscope image actually make up 38 percent of the volu...

When a mineral is the most abundant on the planet, (making up an estimated 38 percent of the Earth's entire volume, in fact), you would think that someone would have given it a name by now. But things are never as simple as they seem. Despite being so prevalent, the substance in question has only ever existed in synthetic form until recently, and the first naturally-occurring example of it didn't even come from beneath the ground; it arrived from outer space.  Read More

An x-ray displaying BoneFinder-enhanced hip bones

Despite what cartoons may have us believe, x-rays don't always show bones as being sharply defined from the surrounding tissue. It's often difficult to tell where the one ends and the other begins, requiring clinicians to go through the images and manually draw in the outlines of bones. Now, however, free software known as BoneFinder is able to do so automatically.  Read More

Four new images have been released to mark the 15th anniversary of the launch of the Chand...

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

Artist's impression of the undersea pipline X-ray in operation (Image: GE)

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
