Current Affairs 04 April 2019 Digest 2: 5G networks in South Korea; CCMB discovers new enzyme

Story 1: South Korea to launch world's first 5G networks

South Korea will launch world’s first 5G mobile networks on April 5, 2019. It would be a transformational leap that already has USA and China sparring for control of an innovation that could potentially change the day-to-day lives of billions of people.

The superfast communications supported by fifth generation (5G) wireless technology will ultimately underpin everything from toasters to telephones; from electric cars to power grids.

Key Highlights


  • It is crucial for the future development of devices ranging from self-driving vehicles that send data traffic to one another in real time to industrial robots, drones and other elements of the Internet of Things.
  • London-based Global System for Mobile Communications says that it is a vital part of the infrastructure of tomorrow, and the 5G standard is expected to bring about USD 565 billion in global economic benefits by 2034.

What is 5G technology?

5G (5th Generation) is the latest generation of cellular mobile communications. It succeeds the 4G (LTE-A, WiMax), 3G (UMTS, LTE) and 2G (GSM) systems. 5G performance targets high data rate, reduced latency, energy saving, cost reduction, higher system capacity, and massive device connectivity. Their major advantage is that 5G networks achieve much higher data rates than previous cellular networks, up to 10 Gbts; which is faster than current cable internet, and 100 times faster than the previous cellular technology, 4G LTE.


Story 2: Centre for Cellular and Molecular Biology discovered a new enzyme

Scientists at the Centre for Cellular & Molecular Biology (CCMB) have discovered a new enzyme which helps in breaking cell walls of bacteria and hence, offers a potential for a new drug delivery route to arrest the anti-bacterial resistance.

Dr Manjula Reddy led the team at the Centre for Cellular & Molecular Biology (CCMB). They have discovered a new enzyme called ‘scissors enzyme’. CMB director Rakesh Mishra and senior scientist Manjula Reddy explained in research that it is crucial to know how cells grow in bacteria to understand the anti-bacterial resistance to currently available antibiotics.
