Dear Aspirants
IASbhai Current Affairs News Analysis | Prelims & Mains 2020 is an initiative to dilute major articles from leading Newspapers in India which are most relevant to UPSC preparation –‘THE HINDU, LIVEMINT , INDIAN EXPRESS’ and help millions of readers who find difficulty in answer writing and making notes everyday. Hence we choose articles on daily basis and analyse them with respect to UPSC PRELIMS 2020.

The greatest danger for most of us is not that our aim is too high and we miss it, but that it is too low and we reach it.– Michelangelo

Kamchatka beach

      HEADLINES:

‘Eco disaster’ unfolding on Kamchatka beach

      WHY IN NEWS:

Straight from DownToEarth

SYLLABUS COVERED: GS 3: Oil spill

      ISSUE: 

An ‘ecological disaster’ of sorts is unfolding on a black volcanic beach of the Kamchatka Peninsula in the Russian Far East

7th Oct Current Affairs News Analysis

ECOLOGICAL DISASTER UNFOLDED

The largest town in Kamchatka reported of burning eyes, throat ache, headache, fever and a fear of losing eyesight on emerging from the water.

SOURCES: FREEWORLDMAPS.NET
  • Then, sea animals begin to die in large numbers, their bodies littering the beach.
  • These included octopuses, seals, sea urchins, stars, crabs and fish.

Examination of the sea water by the administration has shown that levels of phenols and oil compounds have spiked.

  • Another theory being speculated is that ships carrying oil in the vicinity had leaked it into the sea water.

Kamchatka is a UNESCO world heritage site.

      IASbhai WINDUP: 

  • The river displayed a yellow colour.
  • There is a training camp of the Russian military upstream.

Microplastics : Threat to marine environment

      HEADLINES:

Microplastics again: Report flags threat to marine environment along Kanyakumari coast

      WHY IN NEWS:

Microplastics are among major pollutants of the marine environment along the Kanyakumari coast.

SYLLABUS COVERED: GS 3: Conservation of Biodiversity

      ISSUE: 

Pollutants dog remote beaches, marine ports apart from touristy destinations

STUDIED BY

  • The Department of Remote Sensing, Bharathidasan University.
  • The study covered eight different sampling stations along a 71 kilometre coastline comprising both urbanised beaches and undisturbed coastal areas along the Indian Ocean.
  • It yielded baseline data that helped understand occurrence and distribution of microplastics in near-shore sediments.
  • Such tiny particles — less than 5 millimetres — are transported and evaluate their interaction with the region’s marine ecosystem.
  • Primary and secondary microplastics are found in coastal environments all over the world.
  • They are much more hazardous than larget plastic particles as they get into all levels of marine food webs.

RESEARCH ANALYSIS

  • Researchers found an overall higher abundance of microplastics at urbanised beaches due to significant human influence.
  • While tourist beaches had high levels, remote beaches and fishing ports also had large volumes of such debris, affecting the marine food web.

When sediments were analysed, it was found that the tourist beaches have a microplastics pollution with 150 particles (44 per cent).

  • Harbour beaches with 99 particles (28.5 per cent) and coastal stretches along the undisturbed areas with 15 particles (4.3 per cent).
  • These items also likely to contain fibres from clothing and other synthetic textiles .
  • Scientists tracked microplastics samples from different beach sediments, the average of which is found to be up to 43 particles per 50 g dry sediments.

      IASbhai WINDUP: 

  • New research would help to identify mechanisms that influence their transport and deposition in the coastal sediments as well as evaluate the possible interaction between microplastic particles and marine ecosystems.
  • The authors urged policymakers and consumers to take proactive actions focusing on measures that can stop the plastics from intruding and polluting the ocean.

LEDs emitting high-quality white light

      HEADLINES:

Scientists at CeNS find new insights into LEDs emitting high-quality white light

      WHY IN NEWS:

Scientists in their search for methods to produce high-quality white light have unearthed crucial reaction insights that can help design white LEDs.

MINISTRY? :- Ministry of Science & Technology
SYLLABUS COVERED: GS 3: Science and Technology

      ISSUE: 

Colour quality is a key challenge faced in producing white Light Emitting Diodes (LEDs) as a general light source.

RESEARCHERS

Centre for Nano and Soft Matter Sciences (CeNS) is an autonomous research institute under the Department of Science and Technology (DST).

HIGH-QUALITY WHITE LIGHT : LED

CeNS found that though nanocrystals of inorganic chemicals caesium lead halide show the promise of white light emission.

  • It is a very odd behaviour of the nanocrystals prevented them from keeping that promise.
  • The capability of white light emission rests in the fact that the emission from these crystals can be easily tuned over the entire visible spectrum by varying their halide compositions.

7th Oct Current Affairs News Analysis

  • However, they failed to emit white light due to an interparticle mixing between the nanocrystals that resulted in a single emission.

White light needs the presence of red, green and blue spectra of light.

  • So, once the crystals give a single emission, they miss the chance of creation of white light.

PRINCIPLE
Halide ions of the crystals migrate from one particle to another even at room temperature and form an alloy of nanocrystals, which yield a single emission.

      IASbhai WINDUP: 

  • The findings from the present work were recently published in the journal ‘Nanoscale.
  • The understanding of this reaction kinetics will help in developing strategies to prevent interparticle mixing,
  • and the team is pursuing research to create LED that produce good quality white light.

Afghans fear return of Taliban

      HEADLINES:

As peace talks continue, Afghans fear return of Taliban

      WHY IN NEWS:

With U.S. planning to withdraw, people worry Taliban has changed little since darkest days of its regime

SYLLABUS COVERED: GS 2 : IR

      ISSUE: 

Almost two decades after the United States launched air strikes against Afghanistan’s ruling Taliban regime and started what would become America’s longest-ever war, the hardline group is in a stronger position than ever.

AFGHAN PEACE TALKS

  • The invasion that followed those October 7, 2001 strikes quickly toppled the militants, who had harboured the Al-Qaeda, the group behind the September 11 attacks that killed nearly 3,000 people in America just weeks earlier.
  • 19 years since the collapse of their brutal Islamist regime, the Taliban is pushing for a return to power.
  • Having signed a landmark troop withdrawal deal with Washington in February and currently holding peace talks with the Afghan government.
  • Fearful that the Taliban has changed little since the darkest days of its regime — when it killed women accused of adultery, attacked minority religious groups and barred girls from going to school .

Many Afghans worry about a new era of Taliban influence.
 

  • Kabul’s streets are following amputations for petty crimes under the Taliban’s strict interpretation of Sharia law.

      IASbhai WINDUP: 

ENDURING IMPROVEMENTS

  • The 2001 invasion heralded some enduring improvements for young Afghans — particularly girls — and ushered in a Constitution guaranteeing certain freedoms, including the right to education.
  • But so far in peace talks in Doha, which started last month, the Taliban has said little about issues such as women’s rights or freedom of expression.
  • The hardline group and Washington shows the militants have not changed.
