Theyyam

  • Theyyam (TeyyamTheyam or Theyyattam) is a popular ritual form of dance worship in Kerala and Karnataka, India. Theyyam consisted of thousand-year-old traditions, rituals and customs. The people of these districts consider Theyyam itself as a channel to a god and they thus seek blessings from Theyyam.
  • It is ritualistic embodiment of deities
  • Theyyam is performed by males, except the Devakoothu theyyam; the Devakoothu is the only Theyyam ritual performed by women.

Pegasus

  • It is a spyware developed by Israel-based NSO Group
  • The Pegasus spyware can not only mop up information stored on phones such as photos and contacts, but also activate a phone’s cameras and microphones to turn it into a spying device without the owner’s knowledge.
  • The earliest avatars of Pegasus used spear phishing to enter phones. However, it has evolved into “zero-click” attacks with the phones being infected without any action from the target individual.
  • Pegasus used several such “exploits”, or weaknesses, to enter Android and Apple phones; and many of these exploits were reportedly “zero day”, which means even the device manufacturers were unaware of these weaknesses. Pegasus can also be delivered over the air from a nearby wireless transmitter, or manually inserted if the target phone is physically available.

Bomb Cyclone

  • A bomb cyclone is a large, intense midlatitude storm that has low pressure at its center, weather fronts and an array of associated weather, from blizzards to severe thunderstorms to heavy precipitation. It becomes a bomb when its central pressure decreases very quickly—by at least 24 millibars in 24 hours. 
  • When a cyclone “bombs,” or undergoes bombogenesis, this tells us that it has access to the optimal ingredients for strengthening, such as high amounts of heat, moisture and rising air. Most cyclones don’t intensify rapidly in this way. Bomb cyclones put forecasters on high alert, because they can produce significant harmful impacts.
  • The U.S. Eastern Seaboard is one of the regions where bombogenesis is most common. That’s because storms in the midlatitudes—a temperate zone north of the tropics that includes the entire continental U.S.—draw their energy from large temperature contrasts.
