1) World’s first holographic flexible Smartphone developed.
  • Scientists from the Queen’s University (Canada) have developed the world’s first holographic flexible Smartphone named HoloFlex.
  • HoloFlex, is capable of rendering 3D images with motion parallax and stereoscopy to multiple simultaneous users without head tracking or glasses.
  • HoloFlex features a high-definition Flexible Organic Light Emitting Diode (FOLED) touch-screen display.
  • Images are rendered into 12-pixel wide circular blocks rendering the full view of the 3D object from a particular viewpoint.
  • These pixel blocks are projected through a 3D printed flexible micro lens array consists of over 16,000 fish-eye lenses.
  • The Smartphone is also equipped with a bend sensor which allows the user to bend the phone. It helps in moving objects along the z-axis of the display.
2) Baby Biagio is first in Britain to be born through new chromosome screening technique.
  • UK’s first baby named Biagio Russo was born in Oxford using Next-generation DNA sequencing (NGS) method.
  • This method uses a revolutionary In Vitro Fertilization (IVF) technique resulting in better selection of embryos to transfer during the treatment.
  • NGS also known as high-throughput sequencing is bio medical process that allows doctors to easily choose the embryos which have the strongest chance of growing into healthy babies.
  • This method helps doctors to move away from traditional manually count and identify problems caused by embryos produced in IVF having the wrong number of chromosomes.
  • Unlike traditional screening methods, NGS can spot embryos that have more subtle DNA faults and embryos that have only some cells with chromosomal defects.
3) Google launches free public Wi-Fi service at five railway stations.
  • Multinational company Google has announced the launch of its free high-speed public WiFi service at Ujjain, Jaipur, Patna, Guwahati and Allahabad railway stations.
  • Google has been deploying the service over the extensive fibre network of Indian Railway`s arm Railtel which provides Internet services as RailWire.
  • The service is now available in 15 stations across India.
  • This is in continuation with its project to provide high-speed public WiFi service at 100 Railway stations across India by end of the year.
  • Google Covering 100 of the busiest train stations in India, the project will be eventually rolled out to cover 400 train stations across India.
4) NASA’s Kepler telescope 1,284 new planets found outside our solar system by Kepler telescope.
  • NASA’s unmanned Kepler space observatory has discovered the largest trove of exoplanets outside our solar system.
  • It has discovered total of 1,284 exoplanets and it is more than double the number of known exoplanets found with the Kepler space telescope.
  • The new trove of 1,284 exoplanets nearly 550 are said to be rocky planets like Earth, based on their size.
  • NASA has discovered nearly 5,000 total planet candidates, of them more than 3,200 have been verified and 2,325 of these were discovered by Kepler.
About Kepler space observatory:
  1. The unmanned Kepler space observatory was launched in 2009 and was tasked with determining how commonly, Earth-like planets occur throughout the Milky Way galaxy.
  2. The Kepler observatory works by observing a dimming in the light of a star, known as a transit, each time an orbiting planet passes in front of it. 
5) Indian Navy Decommissions Fighter Planes Sea Harriers.
  • The Indian Navy decommissioned its fleet of iconic Sea Harriers at a function organised at INS Hansa base in Vasco, Goa.
  • The Harriers will be replaced by a squadron of Russian MIG 29k jets and the retired aircrafts will be put on display in museums.
About Sea Harriers:
  1. The aircraft was developed by the British in the 1960s. It was used for both reconnaissance and strike.
  2. In India Sea Harriers were inducted in 1983 and played a pivotal role in various operations.
  3. It is best known for the ability to take off and land vertically. It is only class of jet that can hover like a helicopter.
  4. During their service, the aircrafts had operated from both INS Vikrant and INS Viraat aircraft carriers. 
6) Reliance Jio Launches JioMoney Digital Wallet to The Public.
  • Reliance Jio has quietly launched its new wallet app on the Apple and Android app stores.
