1. Section 106 of the Indian Evidence Act
The Supreme Court recently held that Section 106 of the Evidence Act does not inherently impose a burden on the accused but comes into play when the accused fails to provide any explanation regarding facts that should be within their knowledge.

About Section 106 of the Indian Evidence Act:

  • Section 106 of the Indian Evidence Act, 1872, deals with the burden of proof in cases where a fact is within the special knowledge of a person.
  • This section applies to civil and criminal cases alike and lays down an important principle of evidence.
  • The section states that when any fact is especially within the knowledge of any person, the burden of proving that fact is upon that person.
  • This means that if a fact is known to a particular person and not to others, it is the responsibility of that person to prove it in court.
  • For example, in a case where the ownership of a property is disputed, and the disputed property was in the possession of the defendant, the burden of proving that he acquired the property lawfully and has the right to possess it will be on the defendant.
  • Similarly, in a criminal case where the accused is alleged to have killed someone with a knife, the burden of proving that the accused used the knife to commit the crime will be on the prosecution.
  • The burden of proof under Section 106 is not absolute, and the person who has the special knowledge of the fact is only required to prove it to the extent that is reasonable in the circumstances. 
  • The person is not required to prove the fact beyond all doubt, but only to the extent that a reasonable person would believe it to be true.
2. Territorial Army (TA)
The Territorial Army (TA) recently inducted its first batch of Mandarin-trained officers to support the regular Army's efforts to enhance expertise in the Chinese language.

4. Watermeal
Scientists are conducting groundbreaking research into the potential of watermeal, the world's smallest flowering plant, as a source of nutrition and oxygen for astronauts.

About Watermeal:

  • Watermeal is an aquatic plant in the Araceae family.
  • It is the smallest flowering plant in the world and appears as small green seeds. 
  • It is often referred to as "duckweed" because it is a favorite food of ducks.

    • It also produces the world’s smallest fruit, called a utricle.
    • It is a nutritional powerhouse. It is a complete protein, meaning that it contains all nine essential amino acids.
    • In some cases, watermeal can become invasive and form dense mats that cover the entire surface of a water body.
5. Pythagoras
An ancient Babylonian tablet displaying a concept predating Pythagoras by over a millennium suggests the Pythagorean theorem could be the world's oldest known case of plagiarism.

About Pythagoras:

  • Pythagoras was a Greek philosopher and mathematician.
  • Pythagoras lived during the 6th century B.C. on the island of Samos, Greece.
  • He is commonly said to be the first pure mathematician who proposed that everything is a number.
  • He is best known in the modern day for the Pythagorean Theorem.
  • Pythagoras’ Theorem:
    • It states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
    • This formula has been applied to measuring distance and space as, for example, in planning and executing the construction of a building.
  • Pythagorean Brotherhood:
    • Pythagoras founded a secretive religious and philosophical community known as the Pythagorean Brotherhood.
    • The members, known as Pythagoreans, followed a strict set of rules and beliefs, including the idea that mathematics and numbers held mystical and spiritual significance.
    • It was here he taught that "the whole cosmos is a scale and a number.
6. Card-on-File Tokenisation
Recently, the Reserve Bank of India (RBI) proposed to introduce Card-on-File Tokenisation (CoFT).

About Card-on-File Tokenisation:

  • Tokenisation refers to replacement of actual credit and debit card details with an alternate code called the “token”, which will be unique for a combination of card, token requestor and device.
  • This shall be unique for a combination of card, token requestor (i.e. the entity which accepts request from the customer for tokenisation of a card and passes it on to the card network to issue a corresponding token) and the merchant (token requestor and merchant may or may not be the same entity).
  • Advantage: A tokenised card transaction is considered safer as the actual card details are not shared with the merchant during transaction processing.
  • Customers who do not have the tokenisation facility will have to key in their name, 16-digit card number, expiry date and CVV each time they order something online.

What is Card-on-File transaction?

  • It is transaction where in cardholders authorizes merchants to store their payment information securely and bill cardholders’ stored accounts for future purchases.

9. Atmospheric Perturbations around the Eclipse Path (APEP) mission
NASA is set to launch a mission called APEP to study how a solar eclipse affects the upper atmosphere.

About Atmospheric Perturbations around the Eclipse Path (APEP) mission:

  • The mission will involve launching of three rockets equipped with scientific instruments.
  • Objective: To know how the upper atmosphere will change during the eclipse, especially the moment when there would be a sudden reduction in light.
  • During an eclipse, the sudden drop in sunlight causes changes in the ionosphere, creating waves that ripple through this atmospheric layer.
  • It will measure changes in electric and magnetic fields, density, and temperature.
  • This launch will take place at the White Sands Missile Range in New Mexico, with a specific focus on the ionosphere.
  • According to NASA, the ionosphere's temperature and density are projected to decrease during the eclipse, resulting in a wave-like disturbance that has the potential to disrupt GPS and other satellite communications. 
  • The process
    • The rockets will be positioned just outside the path of annularity, where the Moon moves directly in front of the Sun. Each rocket will deploy four small scientific instruments designed to record changes in electric and magnetic fields, density, and temperature.
    • NASA's goal is to achieve the first-ever simultaneous measurements from multiple locations in the ionosphere during a solar eclipse.
    • Rockets can be launched precisely at the right moment and can investigate lower altitudes inaccessible to satellites.
    • Sounding rockets were chosen by the team due to their ability to pinpoint and measure specific regions of space with great accuracy.
    • These rockets can also record changes occurring at various altitudes as they ascend and descend from suborbital flights.
    • The rockets will gather data at altitudes ranging from 45 to 200 miles (70 to 325 kilometres) above the Earth's surface along their flight path.
10. Mytella strigata
Recently, the Southern Bench of the National Green Tribunal (NGT) has asked the Fisheries Department and the Tamil Nadu State Wetland Authority to file a detailed report on the removal of invasive mussel species Mytella strigata from Ennore-Pulicat wetland.

About Mytella strigata  :

  • It is a moderately large and symmetrical shelled mussel.
  • It is generally observed in the middle intertidal and subtidal waters of estuaries and near coastal environments.
  • These mussels attach themselves to surfaces using byssus threads.
  • Appearance: 
  • Individual mussels have a diversity of external colour schemes from black, dark bluish, brown, grey, orange and (rarely) green
  • The species can also have a range of external shell patterns from zig zags, spots or concentric bands.
  • It can form dense clusters that colonise hard substrates or occupy epibenthic habitats, including other mussel species. 
  • It is usually present on both the Atlantic and Pacific coasts of tropical South and Central America.
  • It has spread to Taiwan, the Philippines, Singapore, the Gulf of Thailand, west coast of India and the south-eastern United States.
  • Threats: These mussels spread like a carpet over the river bottoms and thus preventing prawns from grazing or burying themselves in the sediment.
