Genetic test to detect onset of glaucoma

Date: 27 January 2020 Tags: Miscellaneous
  • A group of researchers from Australia has formulated a genetic test that could detect people’s susceptibility towards developing glaucoma.
  • Glaucoma is characterised by progressive damage and degeneration of the optic nerve which also causes gradual loss of vision.
  • There is still no proven cure for the disease, but treatment can reliably slow or halt deterioration in most cases.
  • Glaucoma is a genetic disease and the best way to prevent the loss of sight from glaucoma is through early detection and treatment.

India’s largest gamma-ray telescope in Ladakh

Date: 27 January 2020 Tags: Miscellaneous
  • India will set up the World's highest gamma-ray telescope in the newly formed Union Territory of Ladakh this year.
  • The telescope named  Major Atmospheric Cherenkov Experiment Telescope (MACE) is also India's largest gamma-ray telescope. MACE will be situated at the campus of Indian Astronomical Observatory in Hanle, Ladakh.
  • The MACE is a project collaboration between four premiere Indian institutes- Baba Atomic Research Centre (BARC), Tata Institute of Fundamental Research (TIFR), Indian Institute of Astrophysics (IIA) along with the Electronics Corporation of India Limited (ECIL).

Physics defying particles in Antarctica

Date: 27 January 2020 Tags: Particle Physics
  • Ultra-high-energy particles have blasted up through the ice of Antarctica, setting off detectors in the Antarctic Impulsive Transient Antenna (ANITA) experiment.
  • These events, along with several additional particles detected later at the buried Antarctic neutrino observatory IceCube, don't match the expected behaviour of any Standard Model particles.
  • The particles look like ultra high-energy neutrinos. But ultra high-energy neutrinos shouldn't be able to pass through the Earth.
  • Neutrinos are the faintest particles we know, which are difficult to detect and nearly massless.

Kepler system spots Vampire star system’s super-outburst

Date: 27 January 2020 Tags: Space
  • The NASA spacecraft called Kepler has witnessed an unusual super-outburst from a previously unknown dwarf nova.
  • The star system in question consists of a white dwarf star with a brown dwarf companion about one-tenth as massive as the white dwarf
  • A white dwarf is the leftover core of an aging Sun-like star and contains about a Sun's worth of material in a globe the size of Earth.
  • A brown dwarf is an object with a mass between 10 and 80 Jupiters that is too small to undergo nuclear fusion.
  • They are so close that the white dwarf's strong gravity strips material from the brown dwarf, sucking its essence away like a vampire.

Bodo militant group to sign peace accord

Date: 27 January 2020 Tags: Miscellaneous
  • The Centre is all set to sign an accord with the banned Assam-based insurgent group National Democratic Front of Boroland (NDFB).
  • The accord will provide for some political rights to the Bodo tribals living in Assam and some economic package for the community.
  • However, the territorial integrity of Assam will be maintained and the key demand of the NDFB, which is either a separate state or a UT, is not going to be entertained.
