  • Lake Chad, in the Sahel region, serves as a useful indicator of changing conditions along the border of the Sahara.
  • The study also examined conditions in the Sahel region, the transitional zone connecting the southern Sahara to the Sudanian Savanna.
  • The results suggest that human-caused climate change, as well as natural climate cycles, caused the desert’s expansion.
  • The geographic pattern of expansion varied from season to season, with the largest differences along the Sahara’s northern and southern boundaries.

  • In 2016, blue waves were spotted in the Juhu beach, Mumbai.
  • Though popularly called blue waves, the rare natural phenomena are referred to as bio-luminescence.
  • Bioluminescence is the emission of light by an organism or by a laboratory biochemical system derived from an organism.
  • It results from a chemical reaction in which the conversion of chemical energy to radiant energy is direct and virtually 100 percent efficient.
  • The biological light, or bioluminescence, in the waves is the product of marine microbes called phytoplankton.
  • The presence of phytoplankton known as dinoflagellates in the water is the most common reason for marine bioluminescence.
  • Dinoflagellates have a tail-like structure called flagella that produces light when disturbed, stressed or in high-pollution levels.

Sand Fish

  • The sand fish is a small, robust lizard that prefers to stay under the sand rather than above it.
  • The name sandfish originated because of its ability to move through sand as if it were swimming.
  • A streamlined body and paddle like feet enable it to move through the sand as easily as a fish moves through water.

  • The species is generally found in the North African desert and also in Arabian Desert.
  • A species of sand fish is found in Rajasthan.
  • The sandfish is an insectivore that can detect vibrations the insects in its vicinity create while moving.
