A rocky extrasolar moon (exomoon) with bubbling lava may orbit a planet 550 light-years away from us. This is suggested by an international team of researchers on the basis of theoretical predictions matching observations. The ‘exo-Io’ would appear to be an extreme version of Jupiter’s moon Io.

Jupiter’s moon Io is the most volcanically active body in our solar system...

Investigators have developed a ‘lab on a chip’ technology that can simulate different levels of Non-alcoholic Fatty Liver Disease progression. Non-alcoholic fatty liver disease (NAFLD) – the accumulation of liver fat in people who drink little or no alcohol – is increasingly common around the world, and in the United States, it affects between 30 and 40 percent of adults. Currently, there are no approved drugs for the treatment of NAFLD, which is predicted to soon become the main cause of chronic liver problems and the need for liver transplantation.

Now a team led by investigators at Massachusetts General Hospital (MGH) has developed a “lab on a chip” technology that can simulate different levels of NAFLD progression in cells across a sing...

MIT researchers have developed a simple, low-cost method to 3D print ultrathin films with high-performing “piezoelectric” properties, which could be used for components in flexible electronics or highly sensitive biosensors.

Piezoelectric materials produce a voltage in response to physical strain, and they respond to a voltage by physically deforming. They’re commonly used for transducers, which convert energy of one form into another...

Three times the mass of Jupiter, a first-of-its-kind planet swings around its star on bizarre path. Astronomers have discovered a planet three times the mass of Jupiter that travels on a long, egg-shaped path around its star. If this planet were somehow placed into our own solar system, it would swing from within our asteroid belt to out beyond Neptune. Other giant planets with highly elliptical orbits have been found around other stars, but none of those worlds were located at the very outer reaches of their star systems like this one.

“This planet is unlike the planets in our solar system, but more than that, it is unlike any other exoplanets we have discovered so far,” says Sarah Blunt, a Caltech graduate student and first author on the new study publishing in The Astronomical J...
