Blue Tide

Focus: GS1.

Topic: Important Geophysical phenomena such as earthquakes, Tsunami, Volcanic activity, cyclone etc., geographical features and their location- changes in critical geographical features (including water-bodies and ice-caps) and in flora and fauna and the effects of such changes.


The tide that produces a fluorescent blue hue—bioluminescence—made an appearance on Juhu beach in Mumbai and Devgad beach in Sindhudurg along Maharashtra’s coastline.

About Bioluminescence

  • Bioluminescence has been an annual occurrence along the west coast since 2016 during the months of November and December.
  • The natural phenomenon is characterised by the emission of light produced by phytoplanktons (microscopic marine plants), commonly known as dinoflagellates.
  • The light is produced through a series of chemical reactions due to luciferase (oxidative enzymes) protein, according to E Vivekanandan, consultant and scientist, Central Marine Fisheries Research Institute.


  • Marine scientists said one of the main factors for its occurrence could be eutrophication – the reduction of oxygen in the water – which makes the phytoplanktons very dominant.
  • This is a recurring phenomenon which is caused by bioluminescent plankton called Noctiluca scintillans, commonly known as sea sparkle.
  • While smaller blooms may be harmless, slow moving larger blooms may cause severe hypoxic conditions that result in fish die-offs in an area.
  • Bioluminescence has been observed across India’s coast as well as the coastline of many beaches in the world such as Maldives, Vietnam, Indonesia, USA, Australia and many other countries.
  • Similar to the blue tide, there exists another such phenomenon called red tide or harmful algal blooms that emits red light.
  • It is rare occurrence caused when colonies of algae—simple plants that live in the sea and freshwater—grow out of control while producing toxic or harmful effects on people, fish, shellfish, marine mammals, and birds.

Brain fingerprinting that the accused in Hathras rape case will undergo

Focus: GS3.

Topic: Science and Technology- developments and their applications and effects in everyday life Achievements of Indians in science & technology; indigenization of technology and developing new technology.


Recently CBI officers probing the alleged rape and murder of a 19-year-old Dalit girl in Hathras, Uttar Pradesh, arrived at the Gandhinagar-based Forensic Science Laboratory (FSL) with the four accused for their  brain electrical oscillation signature profiling (BEOSP) test to be conducted .

About Brain Electrical Oscillation Signature Profiling

  • Brain Electrical Oscillation Signature Profiling (BEOSP) also known as brain fingerprinting is a neuro psychological method of interrogation in which the accused’s participation in the crime is investigated by studying their brain’s response.
  • Brain finger printing is based on finding that the brain generates a unique brain wave pattern when a person encounters a familiar stimulus. Use of functional magnetic resonance imaging in lie detection derives from studies suggesting that persons asked to lie show different patterns of brain activity than they do when being truthful.
  • The BEOSP procedure does not involve a question answer session with the accused and is rather a neuro psychological study of their brain.


  • Brain Electrical Oscillation Signature Profiling (BEOSP) also known as brain fingerprinting is a neuro psychological method of interrogation in which the accused’s participation in the crime is investigated by studying their brain’s response.
  • The BEOSP test is carried out via a process known as electroencephalogram, conducted to study the electrical behaviour of the human brain.
  • Under this test, the consent of the accused is first taken and they are then made to wear caps with dozens of electrodes attached to them.
  • The accused are then shown visuals or played audio clips related to the crime to check if there is any triggering of neurons in their brains which then generate brainwaves.
  • The test results are then studied to determine the participation of the accused in a crime.  
  • The tests are based on the phenomenon’s of ‘knowledge’ and ‘experience’.
  • A person’s brain might have knowledge of the crime committed and the alibi they have come up with.
  • But it is the ‘experience’ of having participated in the crime that determines their guilt.”

A climate emergency - New Zealand government

Focus: GS3.

Topic: Conservation, environmental pollution and degradation, environmental impact assessment.


  • The parliament passed the Zero-Carbon Act, which commits New Zealand to zero carbon emissions by 2050 or sooner.
  • New Zealand’s government will decide next week if a climate emergency should be declared in the country or not.
  • As prime minister, Ardern has been vocal about climate change and last November, the parliament passed the Zero-Carbon Act, which commits New Zealand to zero carbon emissions by 2050 or sooner.

About Climate emergency

  • In its ongoing online petition, Greenpeace New Zealand is urging the government to declare a climate emergency since people are “facing more extreme weather events, catastrophic loss of wildlife and a crisis over access to freshwater and food”.
  • In 2019, the Oxford dictionaries declared “climate emergency” to be the word of the year, a word that reflects “the ethos, mood, or preoccupations of the passing year, and have lasting potential as a term of cultural significance”.
  • It defines climate emergency as “a situation in which urgent action is required to reduce or halt climate change and avoid potentially irreversible environmental damage resulting from it”.
  • But even before the New Zealand government planned to declare a climate emergency, some of the regions in the country had already started declaring it since last year.
  • Even so, such a declaration is only symbolic and does not have any legal weight because of which critics have said that such announcements don’t do enough and are, in fact, “hollow”.
  • Some of the countries that have declared a climate emergency in recent years include the UK, Portugal, Canada, France and, most recently, Japan.

About Athena SWAN

  • The Athena SWAN Charter is an evaluation and accreditation programme in the UK enhancing gender equity in science, technology, engineering, mathematics and medicine (STEMM). 
  • Participating research organisations and academic institutions are required to analyse data on gender equity and develop action plans for improvement. 
  • The programme recognises such efforts with bronze, silver or gold accreditation. 
  • Institutions that sign up commit to addressing unequal gender representation; tackling the gender pay gap; removing the obstacles faced by women in career development and progression; discriminatory treatment often experienced by trans people; gender balance of committees and zero tolerance for bullying and sexual harassment.
