Astronomers Identify Closest Black Hole to Earth - VOA Learning English
2019 BMW S1000 RR Review: India’s best 1000cc Superbike is stupendously phenomenal!
BMW S1000 RR was launched about 10 years back to dominate the litre-class superbike segment and that it did with authority. Now there's a brand new version that is lighter, faster, smarter and easier to ride. Well, that's what BMW claims so we headed out to the Buddh International Circuit to find out how good the new BMW S1000 RR really is and what is that leaves room for improvement.

A new guidance is now available to facilitate the ecological risk assessment of organometallic and organic metal salt substances
The OECD has published guidance to facilitate the ecological risk assessment of organometallic and organic metal salt substances. A strategy is presented based on key steps that first consider the fate of these substances in the environment, the identification of moieties of concern, and subsequently the selection of an appropriate path forward to either assess the inorganic moiety and/or the individual substance.
Genome Editing: Applications in Agriculture
The OECD Conference on Genome Editing: Applications in Agriculture – Implications for Health, Environment and Regulation will explore the regulatory considerations raised by genome edited products, with the aim to favour a coherent policy approach to facilitate innovation involving genome editing.

Nanometre-sized droplets from a gas dynamic virtual nozzle
This work describes a method to characterize the size distribution of individual aqueous droplets in a high-density and polydisperse aerosol. It is shown that droplets smaller than 120 nm can be generated by purely mechanical means using a gas dynamic virtual nozzle, and theoretical models are provided for the different flow regimes investigated.
Orientational disorder of monomethyl-quinacridone investigated by Rietveld refinement, structure refinement to the pair distribution function and lattice-energy minimizations
The crystal structure of the organic pigment 2-monomethyl-quinacridone (Pigment Red 192, C21H14N2O2) was solved from X-ray powder diffraction data. The resulting average structure is described in space group Poverline 1, Z = 1 with the molecule on the inversion centre. The molecules are arranged in chains. The molecules, which have no inversion symmetry, show orientational head-to-tail disorder. In the average structure, the methyl group is disordered and found on both ends of the molecule with an occupancy of 0.5 each. The disorder and the local structure were investigated using various ordered structural models. All models were analysed by three approaches: Rietveld refinement, structure refinement to the pair distribution function (PDF) and lattice-energy minimization. All refinements converged well. The Rietveld refinement provided the average structure and gave no indication of a long-range ordering. The refinement to the PDF turned out to be very sensitive to small structural details, giving insight into the local structure. The lattice-energy minimizations revealed a significantly preferred local ordering of neighbouring molecules along the [0ar 11] direction. In conclusion, all methods indicate a statistical orientational disorder with a preferred parallel orientation of molecules in one direction. Additionally, electron diffraction revealed twinning and faint diffuse scattering.
Radio telescopes give astronomers rare glimpse at a young protostar’s formation
The way that massive stars form remains mysterious, in part, because massive stars are rare and tend to spend their youth shrouded by dust and gas and hidden from view.

Astronomers Find Super-Earth Using Amateur, Off-the-Shelf Technology
The newfound world, GJ1214b, is about 6.5 times as massive as the Earth. Its host star, GJ1214, is a small, red type M star about one-fifth the size of the Sun. GJ1214b orbits its star once every 38 hours at a distance of only 1.3 million miles. Astronomers estimate the planet's temperature to be about 400 degrees Fahrenheit. Although warm as an oven, it is still cooler than any other known transiting planet because it orbits a very dim star.

Distant, dying star gives astronomers preview of the fate of our Sun
Chi Cygni pulses once every 408 days. At its smallest diameter of 300 million miles, it becomes mottled with brilliant spots as massive plumes of hot plasma roil its surface. As it expands, Chi Cygni cools and dims, growing to a diameter of 480 million miles—large enough to engulf and cook our solar system out to the asteroid belt.

Can we spot volcanoes on alien worlds? Astronomers say yes
Now that astronomers are finding rocky worlds orbiting distant stars, they're asking the next logical questions: Do any of those worlds have volcanoes? And if so, could we detect them? Work by theorists at the Harvard-Smithsonian Center for Astrophysics suggests that the answer to the latter is a qualified "Yes."

Astronomers find giant, previously unseen structure in our galaxy
NASA's Fermi Gamma-ray Space Telescope has unveiled a previously unseen structure centered in the Milky Way--a finding likened in terms of scale to the discovery of a new continent on Earth. The feature, which spans 50,000 light-years, may be the remnant of an eruption from a supersized black hole at the center of our galaxy.
