Astronomers discover 2,000-year-old remnant of a nova

Researchers have discovered the remains of a nova in a galactic globular cluster, located near the center of Messier 22. The finding, using modern instruments, confirms one of the oldest observations of an event outside the solar system. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2019/04/190429125350.htm

Record solar hydrogen production with concentrated sunlight

Researchers have created a smart device capable of producing large amounts of clean hydrogen. By concentrating sunlight, their device uses a smaller amount of the rare, costly materials that are required to produce hydrogen, yet it still maintains a high solar-to-fuel efficiency. Their research has been taken to the next scale with a pilot facility installed on the EPFL campus. from All Top News -- ScienceDaily https://www.sciencedaily.com/releases/2019/04/190429111853.htm

Filaments and fibers three times finer than a human hair

Experts have discovered that there is a moment at which a polymer in liquid state -- specifically one that has been worked from polyethylene glycol, which is widely used in industry -- shows greater elasticity that, instead of breaking up and forming drops, the liquid experiences a stretching which causes filaments to be formed. from Top Technology News -- ScienceDaily https://www.sciencedaily.com/releases/2019/04/190429111859.htm
