Science & Tech

NBRC team uncovers how damaged neurons recover functions

  • Researchers at the National Brain Research Centre, Gurgaon, have experimentally demonstrated how neurons that are injured or damaged can be functionally restored by fusion of the severed axons.
  • Neurons can break during accidental injury and day-to-day stress-induced injury.
  • Carpel tunnel syndrome is a typical case of peripheral nerve damage arising from several severed axons.
  • Neuronal damage arises when the axons are severed into distal and proximal fragments.
  • Functional recovery takes place in an age-dependent manner, with better recovery in the late larval stage and less recovery in adult worms.
  • The researchers used two femtosecond lasers to locate and cut the axons involved in touch sensation.
  • During regeneration, only the axons that successfully fuse with their distal counterparts contribute to functional recovery


The lowdown on the dengue epidemic

The New Initiative- The Global Alliance To Power Past Coal

  • The National Vector Borne Disease Control Programme (NVBDCP) records show that 1,29,329 people fell sick with dengue this year, while 200 died.
  • India’s official numbers are well known to be gross underestimates, with private hospitals often not reporting the disease.
  • 2017 is an extraordinary year.
  • This is due to three reasons.
  • First, India is getting better each year at reporting dengue, leading to more cases being counted. Second, dengue itself is becoming more endemic due to urbanisation.
  • The dengue mosquito thrives in urban habitats, in water pooled under a flower pot for example.
  • As population explodes in rural areas, what was initially an urban disease has moved to these regions too,
  • The dengue virus has four serotypes, or types that are classified by the type of antigen (a molecule on the viral surface which human antibodies recognise) they have.
  • These serotypes are DENV-1, DENV2, DENV-3 and DENV-4.
  • When a person is affected by one dengue serotype, she develops antibodies against it, which protect her for the rest of her life.
  • If the same person is then infected by a different serotype, she is likely to develop severe disease.
  • This is because, in some cases, antibodies against the first serotype worsen the second infection, instead of protecting against it.
  • This phenomenon is called antibody-dependent enhancement (ADE) and results in a more dangerous illness called dengue haemorrhagic fever (DHF).


The UNFCCC Climate Change Conference (COP23)

Where –

  • was held in Bonn, Germany
  • and was presided over by Government of Fiji.

What -

  • It concluded with countries putting in place a roadmap for ‘Talanoa Dialogue’, a year-long process to assess countries’ progress on climate actions.
  • The Conference also made progress on framing rules for implementing 2015 Paris Agreement on climate change and brought rich nations on board on their pre-2020 commitments as demanded by developing nations.

Enlighten about COP-23

  • The conference provided countries around world took opportunity to showcase their actions taken to full pledges under landmark 2015 Paris agreement as well as took other decisions including ‘Talanoa Dialogue’.
  • It also made progress on framing rules for implementing Paris Agreement post-2020 and brought rich nations on board to walk the talk on pre-2020 commitments.
  • However, the differences over climate financing continued

Enlighten About Talanoa Dialogue

  • Talanoa is a traditional approach used in Fiji and other Pacific islands to engage in an inclusive, participatory and transparent dialogue to resolve differences without putting any blame on any one.
  • As per COP23 decision, it has been structured around three questions to arrive at answers with consensus: Where are we? Where do we want to go? How do we get there?
  • The dialogue will be conducted in a manner that promotes enhanced ambition.
  • It will help parties to UNFCCC review their actions and discuss way forward in terms of raising ambitions before 2020.
  • It will consider efforts of Parties on mitigation action and financial and technical support, as appropriate, as one of its elements, in the pre-2020 period under 1997 Kyoto Protocol.

Obligations under Kyoto Protocol

  • The COP23 outlined what all the rich nations need to do as far as their pre-2020 actions under Kyoto Protocol are concerned.
  • It was crucial demand of developing countries.
  • The pre-2020 actions refer to existing obligations of small group rich and developed nations to take mitigation actions under Kyoto Protocol.
  • On the other hand, post-2020 actions are meant for all countries as per their nationally determined contributions (NDCs) under 2015 Paris Agreement.

Conference of Parties (COP)

  • COP is the supreme decision-making body of United Nations Framework Convention on Climate Change (UNFCCC).
  • All States that are Parties to UNFCCC are represented at COP.
  • At COP, all parties review implementation of Convention and take decisions necessary to promote the effective implementation of Convention.


Gleadovia konyakianorum: Parasitic plant found in Nagaland

  • Scientists from Botanical Survey of India (BSI) have discovered a new species of parasitic flowering plant named Gleadovia konyakianorum.
  • The species was named in honour of Konyak tribe of Nagas.
  • The plant was discovered in the semi-evergreen forest at an altitude of 1,500-1,600 metres during an exploration near Tobu town of Mon district in eastern Nagaland.
  • Parasitic plants are often referred to as curious plants, as they steal their nutritional needs from the host

Gleadovia konyakianorum

  • Gleadovia konyakianorum is a holoparasite (complete parasite) plant that derives its entire nutritional requirement from the host plant, which is a Strobilanthes species.
  • It has no chlorophyll (which helps a plant make its own food using sunlight).
  • Though it has no chlorophyll, the plant has a vascular system and extracts its nutrition from the host plant with the help of a haustorium.
  • A haustorium is specialised structure with which plant parasites attach themselves to host plants and derive nutrition.
  • Gleadovia konyakianorum species is root parasite that grows up to 10 cm in height, and bears white, tubular owers.
  • It is only the fourth species from the genus Gleadovia to be found in the world.
  • The other three are Gleadovia banerjiana (discovered in Manipur), Gleadovia mupinense (found in China) and Gleadovia ruborum (discovered in Uttarakhand and also reported from China).
  • Its protection status has been described as ‘data decient’ as per International Union for Conservation of Nature (IUCN) Red List of Threatened Species criteria
