Twitter launches #PowerOf18 campaign to boost youth engagement for 2019 polls

Twitter India has launched #PowerOf18 campaign aimed at encouraging youth to contribute in public debates and participate in civic engagement for the 2019 general elections. The initiative was launched by Twitter CEO Jack Dorsey and Maya Hari, Vice-President and Managing Director, Asia Pacific, Twitter during townhall chat with the students of IIT Delhi.

#PowerOf18 campaign

The campaign will serve as resource for young Indians to find more information about elections, support social causes they are passionate about and join public conversation. It is supported by Twitter’s mission to serve the public conversation and work with more like-minded partners and personalities to create awareness of importance of voting.


In a nationwide survey conducted with 3,622 youth respondents from India, Twitter found rising importance of social media for information consumption. It found that overwhelming 94% of respondents indicating that they would vote in the upcoming elections. Nearly 60% of youth surveyed would turn to social media to find out what’s happening in India and around world, a percentage higher than all other mediums including newspapers.

SpiNNaker: Largest brain-mimicking supercomputer switched on

The world’s largest supercomputer Spiking Neural Network Architecture (SpiNNaker) machine designed to work in same way as human brain was switched on for the first time.


It designed and built at University of Manchester in UK. It can model more biological neurons in real time than any other machine on planet. Biological neurons are basic brain cells present in nervous system that communicate by emitting ‘spikes’ of pure electro-chemical energy. It is neuromorphic computing that uses large scale computer systems containing electronic circuits to mimic these spikes in a machine.

It is capable of completing more than 200 million million actions per second, with each of its chips having 100 million transistors. It is unique as it mimics the massively parallel communication architecture of brain, sending billions of small amounts of information simultaneously to thousands of different destinations. It also unique because, unlike traditional computers, it does not communicate by sending large amounts of information from point A to B via  standard network.

Potential Applications

It has massive potential for neurological breakthroughs in science such as pharmaceutical testing. It can be used to harnessed to control robot which can interpret real-time visual information and navigate towards certain objects while ignoring others.

It can also help to unlock some of secrets of how human brain works by running unprecedentedly large scale simulations. It will allow roboticists to design large scale neural networks into mobile robots so they can walk, talk and move with flexibility and low power.
