New research published today in Nature Astronomy describes an unusual long-distance relationship involving a radioactive gas cloud, called Fermi J1913+0515, and a microquasar, called SS 433, both of which reside inside the Milky Way galaxy. Data gathered over the past 10 years suggests the objects are inextricably connected and working in sync, despite the enormou

Located 15,000 light-years from Earth, microquasar SS 433 is one of the most fascinating places in the galaxy. Its a binary system that consists of a compact object, most likely a black hole but possibly a neutron star, and an overweight star. The presumed black hole weighs in at between 10 and 20 solar masses in which 1 solar mass is equal to the bulk of our Sun , while the star has a mass of 30 solar masses. Stuck together, the objects spin around each other once every 13 days. SS 433 is a pint-sized version of a normal quasar, a type of cosmic object that encompasses vastly heavier black holes packed with millions of solar masses.

A new paper out in Applied Physics Letters today details a method for transforming fish scales into an energy harvester. Researchers processed the raw scales to make them flexible and then attached two electrodes to each scale before laminating it. The resulting cell could then harvest energy from movement around it, including motion as simple as just vibrations or even a heartbeat. This has researchers suggesting that they could one day use it to power things like pacemakers. In the future, our goal is to implant a bio-piezoelectric nanogenerator

Then it will degrade when no longer needed.
