22 June Current Affairs

Centre for Humanitarian Forensics

  • Gujarat is set to come up with the world’s first International Centre for Humanitarian Forensics (ICHF).
  • It will facilitate better management of bodies during emergencies such as disasters.
  • It was inaugurated at the Gujarat Forensic Sciences University (GFSU).
  • It is a joint venture of the International Committee of the Red Cross (ICRC) Regional Delegation for India, Bhutan, Nepal and the Maldives, and GFSU.

Legalisation of Marijuana

  • Canada is to become the second country in the world to fully legalise marijuana after Uruguay.
  • It paves the way for recreational cannabis to be legally bought and sold within the next two or three months.
  • Medical marijuana is already legal in Canada.
  • Marijuana is a psychoactive drug from the Cannabis plant used for medical, recreational & religious purposes.
  • Cannabis can be used by smoking, vaporization, within food, or as an extract.
  • It creates mental and physical effects, such as a “high” or “stoned” feeling, a general change in perception, and an increase in appetite.
  • Short term side effects may include a decrease in short-term memory, dry mouth, impaired motor skills, red eyes, and feelings of paranoia or anxiety.
  • Long term side effects may include addiction, decreased mental ability and behavioural problems in children whose mothers used cannabis during pregnancy.

Sub-Saturn like Planet

  • A team of Scientists from India has discovered a sub-Saturn or super-neputune size planet around a sun-like star.
  • It has mass of about 27 Earth Mass and size of 6 Earth Radii.
  • The planet will be known as EPIC 211945201b or K2-236b.
  • With this discovery, India has joined a handful of countries, which have discovered planets around stars beyond our solar system.
  • The discovery was made by measuring the mass of the planet using the indigenously designed “PRL Advance Radial-velocity Abu-sky Search” (PARAS) spectrograph.
  • PARAS is the first of its kind spectrograph in Asia, which can measure the mass of a planet going around a star.
  • The spectrograph is integrated with telescope at PRL’s Gurushikhar Observatory in Mount Abu, India.
  • Very few spectrographs exist around the world that can do such precise measurements.

Longer Daylight – Summer Solstice

  • June 21st had longer daylight hours (Summer Solstice) than any other day in a year.
  • The reason behind is Earth’s tilt – the axis of rotation of earth is tilted at an angle of 23.50.
  • It is combined with factors such as Earth’s spin and orbit leads to variations in the duration of sunlight on any location on different days of the year.
  • Solstice – On the Equator, day and night are equal every day.
  • At latitudes of 23.5° (from the equator) are the Tropics of Cancer and Capricorn, north and south of the Equator.
  • On each Tropic, the sun is directly overhead at noon once a year.
  • When this happens on the Tropic of Cancer, it is summer solstice in the northern hemisphere.
  • When on the Tropic of Capricorn, it is winter solstice in the northern Hemisphere.
  • At 66.5° (from the equator) are the Arctic and Antarctic Circles, north and south.
  • It is at latitudes higher than 66.5° (in either direction) that days of constant darkness or light occur.
