Space telescopes uncover supermassive black hole winds

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

Researchers use X-ray and CAT scans to reveal the secrets of golden age violins

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

What's in a name? Earth's most abundant mineral finally gets one

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.

Can crowdfunding give us safe fusion power by 2020?

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

New data disregards present theory on the formation of star clusters

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.

GE using medical X-rays to inspect undersea pipelines

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
