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.
  • The white aircraft features wing-mounted solar cells and has a wingspan of about 43 feet.
  • It will build unmanned drones that can fly at 60,000 feet or more.
 

 

9) US successfully launches world`s largest rocket.

  • The world`s largest rocket is set to launch a secret spy satellite to space from Florida
  • The exact details of its intelligence agency cargo is something that the US government is keeping a closely guarded secret.
  • The United Launch Alliance (ULA), a joint space delivery service by aerospace giants Lockheed Martin and The Boeing Company, carried out the launch of a Delta IV Heavy rocket.
  • It saw the triple engine craft roar from its launch pad at the Cape Canaveral Air Force Station, traveling at the speed of sound before soaring beyond the atmosphere.
  • The National Reconnaissance Office (NRO) is perhaps one of the lesser-known US intelligence agencies, the function of which were only made known to the public back in 1992.
  • The office is largely responsible for producing spy satellites and improving hardware sent out to space.
  • It is believed that the latest Delta IV rocket launch is again part of that bid to have ``eyes and ears`` in difficult to reach places, although the exact purpose or location of the satellite is unknown.
10) China launches 23rd navigation satellite BeiDou Navigation Satellite.

  • MacOS will also gain enhanced Continuity and iCloud drive support - Apple’s system that allows apps on iOS to link directly to the Mac versions using iCloud so that users can start something on one device and continue it on another.
  • The biggest change will be a proximity-based system called Auto Unlock that allows users to unlock their Mac computers using an Apple Watch, without having to enter in their password.
  • Apple also introduced Apple Pay for the web that allows users to authenticate payments on their Mac via their iPhone or Apple Watch.
  • An update to iCloud Drive will also share files stored on the desktop across Macs and iOS devices, while a new feature called Optimised Storage will remove unnecessary files from computers after they’ve been backed up which should free up space on existing Macs.
13) NASA detects first methane leak on Earth from space.
  • In a first, an instrument onboard an orbiting spacecraft has measured the methane emissions from a specific leaking facility on Earth’s surface.
  • The observation has been done by the Hyperion spectrometer on NASA’s Earth Observing-1 (EO-1).
  • The leak occurred over Aliso Canyon near Porter Ranch in California.
  • The methane leak was detected successfully by the Hyperion instrument on three separate overpasses during the winter of 2015-16.
  • The orbital observations from Hyperion were consistent with airborne measurements made by NASA’s Airborne/Infrared Imaging Spectrometer (AVIRIS) imager flying onboard a NASA ER-2 aircraft.
  • This is the first time the methane emissions from a single facility have been observed from space.
14) Scientists find giant new planet orbiting two suns.
  • Scientists have discovered a Jupiter-like planet, Kepler-1647b (part of the Kepler-1647 system), orbiting a system of two stars, making it the largest such cosmic body ever found.
  • Dubbed Kepler-1647b, the Jupiter-like planet lies in the constellation Cygnus. It is 3,700 light-years away.
  • The planet was discovered by astronomers from NASA’s Goddard Space Flight Centre and San Diego State University (SDSU).
  • Kepler1647b’s mass and radius nearly identical to that of Jupiter. This makes it the largest transiting circumbinary planet ever found.
  • It is about 4.4 billion years old i.e. roughly the same age as the Earth.
