First species of Yeti crab named Kiwa Tyleri found in Antarctica

Team of British scientists have discovered the first species of Yeti crab from hydrothermal vent systems in Antarctica. Study in this regard was published in the journal Plos One.

Researches have christened this species as Kiwa Tyleri after world-renowned British deep-sea and polar biologist professor Paul Tyler.

Characteristics of Kiwa Tyleri

  • Kiwa Tyleri species are found usually in warm-water refuge of hydrothermal vent systems surrounded by the cold polar waters in the Southern Ocean near Antarctica.
  • It lives in very limited sized habitat near the warm-water hydrothermal vent site.
  • This species is unable to move between vent sites because of the hostile, low temperature and extreme polar environment. So they, occur in highly-packed densities.
  • For food it is dependent on chemosynthetic bacteria which overgrow the surfaces of hydrothermal vent chimneys.
  • Its body is densely covered by bristles known as setae. It has fur like appearance due to bacteria living on it.

Terms

  • Hydrothermal vent systems: It is a fissure releasing geothermally heated water which comes out on planet’s surface. Commonly found in active volcanic places.
  • Chemosynthetic bacteria: They obtain energy from exothermic oxidation of inorganic or simple organic compounds in absence of light. This energy is utilized for metabolic processes.

India, South Africa renew science and technology cooperation pact

India and South Africa have renewed an agreement to extend cooperation in the various fields of science and technology such as astronomy, social innovation, biotechnology, agriculture and indigenous knowledge systems.

It was renewed by signing Fourth Programme of Cooperation during the 10th Joint Committee meeting on Science and Technology Cooperation between both nations held in Johannesburg, South Africa.

Now the signed agreement will extend for the next three years i.e. till 2018. It should be noted that in 1995 both nations had signed a bilateral agreement in the field of science and technology.

During these 20 years of successful science and technology cooperation both nations had undertaken 74 joint research projects in various areas and played important role in important strategic role in South-South cooperation.

They successful science and technology cooperation was undertaken in areas such as information science, biotechnology, astronomy, technologies for rural applications, food science, nanotechnology, indigenous knowledge systems and renewable energy.

Galaxy named as CR7 after footballer Cristiano Ronaldo

Astronomers have named a newly discovered galaxy as CR7 (COSMOS Redshift 7) after Portuguese footballer Cristiano Ronaldo.

Ronaldo is famously known as CR7 after his initials and his jersey number.  He had won Fifa’s Ballon d’Or award consecutively for two years in 2013 and 2014 and has scored a staggering 66 goals this season.

Facts about CR7 galaxy

  • CR7 discovered by a team of astronomers led by Dr. David Sobral from the University of Lisbon in Portugal and Leiden Observatory in the Netherlands.
  • It was discovered by using European Southern Observatory’s (ESO’s) Very Large Telescope (VLT).
  • CR7 is three times brighter compared to Himiko galaxy which was earlier thought be as brightest distant galaxy known to mankind.
  • It is part of the early universe which contains the first generation of stars i.e. known as Population III stars.
  • CR7 belongs to the age of the ancient Universe which existed 800 million years after the Big Bang. This period is known as reionization period.

Population III stars: They are first generation of stars which are born out of the primordial material of the Big Bang. It is believed that Population III stars are several hundred or even a thousand times more massive than our Sun and it is more blazing hot, transient, exploding as supernovae after only about 2 million years ago.
