  • Scientists work toward storing digital information in DNA
    • DNA: Deoxyribonucleic acid.
    • Scientists are working towards making the genetic material capable to store data for long time.
    • DNA: is essentially a biological information-storing molecule and it carries the genetic instructions used in the growth, functioning and reproduction of all living beings.
  • How DNA store information:
    • The information in the DNA is stored in strings i.e. in the form four-letter DNA code composed of combinations/Sequences of A (Adenine), C (Cytosine), T (Thymine) and G (Guanine).
    • How Computers and other device store information:
    • Digital devices store information in binary format (1s and 0s) i.e. in a two-letter code that produces strings of 1s and 0s. For ex. capital ‘A’ stored as 01000001 in binary format.
    • Now Scientist are working towards converting and storing digital information in DNA. This involves translating between the two sequences or codes of four building blocks. For ex. capital ‘A’ converted and stored as AATATG.
    • The DNA digital data storage technology uses artificial DNA made using oligonucleotide synthesis machines.
  • Advantages:
    • Extensive Long durability. Example Scientist can do analysis of thousands of years old human skulls and give credible information.
    • Information stored in DNA consumes very little space.
  • Challenges:
    • The present cost of such technology is very high.
  • Indian Wrestler Narsingh Yadav fails Dope Test: NADA
  • NADA (National Anti-Doping Agency)
    • Autonomous national organization, which is responsible for promoting, monitoring and coordinating the doping control program in sports in all its forms in India.
  • Javelin thrower Neeraj Chopra (18) created history by becoming first Indian Junior athlete to create a World Record in Junior athletics Championship.
    • In the IAAF Under-20 World Athletics Championship held in Bydgoszcz, Poland, Neeraj set new record by throwing javelin at a record distance of 86.48 m in his second attempt.
  • India’s first Green Rail Corridor was inaugurated on the 114-km long Rameswaram-Manamadurai stretch in Tamil Nadu.
  • Green Rail Corridor: Zero toilet discharge.
  • Public sector Hindustan Organic Chemicals Limited (HOCL) going to shutdown operations owing to incurring losses.
    • Company has two facilities 1. At Kochi 2. Rasayani (Maharashtra)
    • The Company started losses since 2012, when dumping of acetone and phenol from other countries began.
  • Notice for privilege motion against Jairam
  • Important is What is Privilege Motion:
    • Privilege motion is a notice by any member of either House of Parliament/State Legislature, against anyone who are accused of breach of privilege.
    • Parliamentary privileges are certain immunities and rights enjoyed by MPs, MLAs and MLCs, individually as well as collectively, to enable them to effectively discharge their functions.
    • When any of these immunities or rights is disregarded, the offence is called a breach of privilege and is punishable under law of Parliament or the state legislature.
    • Here, SAD MP Sukhdev Singh Dhindsa alleged that the Congress MPs misbehaved with Ms. Badal and so gave notice for privilege motion.
