6) Four New Elements Added to Periodic Table.
  • The International Union of Pure and Applied Chemistry (IUPAC) has announced the names proposed for the new elements, whose discovery helped complete the seventh row of the Periodic Table.
  • They are Nihonium (Nh), Moscovium (Mc), Tennessine (Ts), and Oganesson (Og).
  • All of the elements are man-made, created in labs by nuclear researchers. Those researchers are from Japan, Russia and the United States.
  • The chemistry union usually likes names that are easy to translate across major languages. The names must have endings like ``-ium``, ``-ine`` or ``-on``, depending on the grouping of elements they belong to.
7) Scientists turn CO2 into rock to combat climate change.
  • Carbon dioxide has been pumped underground and turned rapidly into stone, demonstrating a radical new way to tackle climate change.
  • The pioneering experiment in Iceland mixed CO emissions with water and pumped it hundreds of metres underground into volcanic basalt rock where it rapidly turned into a solid.
  • The new way was discovered as by Scientists from Columbia University’s Lamont-Doherty Earth Observatory and other institutions as part of a pilot program called CarbFix project.
  • Carbon dioxide is a key factor in global warming, and experts have long called for innovative ``carbon capture and storage`` solutions.
  • This technique the speedy carbonation has potential to combat climate change and may provide a safer, faster way to sequester CO2 and limit global warming.
8) Aerospace firm successfully tests solar-powered aircraft.
  • A test pilot successfully flew a solar-powered prototype aircraft for a company that envisions manufacturing a fleet of drones to provide aerial internet service for an estimated 4 billion people worldwide.
  • The test flight by Luminati Aerospace LLC took place at a former Northrop Grumman defense plant on eastern Long Island that once made military aircraft.
