Science & Technology Current Affairs February 3rd Week 2016

1) Android app MyShake helps your phone to detect earthquakes.
  • University of California, Berkeley scientists have developed an Android app that can detect earthquakes using smart phones, Called MyShake.
  • It is available in the Google Play Store.
  • MyShake utilizes the motion sensors of a Smartphone to identify indications of tremors and merge the signs with the data collected from other users.
  • The smartphone user is connected to a crowd sourced seismic station network and they are able to substantiate an earthquake simply by keeping their phone turned on.
  • The scientists have designed the app in such a way that it can analyse various levels of vibrations picked up by a Smartphone’s inbuilt accelerometer to determine the size and threat of earthquakes. 
2) Ringing Bells to launch India’s cheapest sub Rs. 251 smartphone.
  • Domestic handset maker Ringing Bells, Noida-based company will launch India`s most affordable smartphone for under Rs. 251.
  • And move that is set to disrupt the booming handset market in the country.
  • The launch is in line with Prime Minister Narendra Modi’s vision for “empowering India to the last person, transforming India’s growth story”, the Noida-based company.

  • The discovery was made by a team of engineers led by Indian-Orgin Ashutosh Tiwari.
  • SnO is a new kind of 2D semiconducting material for electronics that opens the door for much speedier computers and smartphones that consumes less power.
  • SnO semiconductor is made of the two elements tin and oxygen. It is first stable P-type 2D semiconductor material ever in existence.
  • It is a layer of 2D material with thickness of only one atom and consumes less power.
  • It has ability to allow electrical charges to move through it much faster (100 times) than conventional 3D materials such as silicon. 

4) Prithvi-II missile successfully test-fired from Chandipur.
  • Indigenously developed Prithvi-II missile was successfully test fired from the Chandipur, off Odisha coast.
Test: It was conducted by the Strategic Force Command (SFC) and was monitored by the scientists from Defence Research and Development Organisation (DRDO).
The missile test was carried out from a mobile launcher from launch complex-3 of the Integrated Test Range (ITR). The test has met all its mission objectives.
About Prithvi-II missile:
Prithvi-II missile is the first missile to be developed by DRDO under India’s prestigious IGMDP (Integrated Guided Missile Development Program).

  • It is cylindrically shaped and is 14 meters long and weighs 2.7 tonnes.
  • It is the heaviest scientific satellite Japan has worked on.
  • The satellite has been equipped with four X-ray telescopes and two gamma-ray detectors.
 
6) DRDO to conduct captive flight trails of anti-radiation missile.
  • The Defence Research and Development Organisation (DRDO) will begin captive flight trails of a radar-destroying missile by April-May 2016.
  • The Indian Air Force would be inducting the anti-radiation missile (ARM) within two years, following the completion of all the developmental trails.
  • During captive flight trials DRDO scientist will evaluate performance of the missile’s heat seeker, structural capability, navigation and control system and aerodynamic vibrations.
  • This indigenously built tactical missile, developed by the Hyderabad-based Defence Research and Development Laboratory (DRDL).
  • The missile uses dual pulse propulsion system as in the case of LR-SAM (Long Range Surface-to-Air Missile) instead of thrust propulsion.
  • ARM has range of 100 to 125 km and will be mounted on combat aircraft Sukhoi (Su-30) and Tejas-Light Combat Aircraft (LCA).
 
7) World`s first wireless flexible smartphone developed.
  • Scientists claim to have developed the world`s first wireless flexible smartphone that allows users to feel the buzz by bending their apps.
  • Researchers at Queen`s University`s Human Media, Canada Lab developed ReFlex.
  • It was full-colour and high-resolution smartphone that combines multi-touch with bend input allowing users to experience physical tactile feedback when interacting with their apps through bend gestures.
  • And also playing games without even touching the display of the screen.
About features:
  1. ReFlex is based on a high definition 720p LG Display Flexible OLED touch screen powered by an Android 4.4 “KitKat” board mounted to the side of the display.
  2. Bend sensors behind the display sense the force with which a user bends the screen, which is made available to apps for use as input.

  • Sri Lanka will benefit on a large scale with Project Loon as high speed internet connectivity becomes cheaper and more affordable, which was the vision behind Project Loon.
  • Project Loon is a research and development project being developed by Google X with the mission of providing Internet access to rural and remote areas.
11) NASA finds `Super-Earth` with an atmosphere.
  • Astrophysicists at NASA, working with the ESA and the University College London, found a ``Super-Earth`` exo-planet with an atmosphere for the first time.
  • The Hubble telescope’s Wide Field Camera 3 (WFC3) first discovered the planet, dubbed 55 Cancri e, which is only around 40 light years away.
  • It is located extremely close to its planet star, which heats its surface to a staggering 2,000 degrees Celsius making it only known super-Earth with such a high temperature.
  • 55 Cancri e’s atmosphere largely consists of hydrogen (H) and helium (He) similar to gas giant planets with no traces of water and doesn’t sustain life.
  • Super-earths are merely rocky planets that are larger than the Earth. They’re widely supposed to be the most common type of rocky planet in the galaxy.
