  • Mosquito-borne diseases

  • Malaria - This disease is caused by the bite of a female Anopheles mosquito.

  • Malaria fever is caused by a virus called Plasmodium vivax.

  • Dengue - Dengue virus is transmitted to humans through the bite of an infected Aedes mosquito.

  • According to the World Health Organisation (WHO), dengue is the most widely spread disease by mosquitoes worldwide.

  • Chikungunya - Chikungunya, like dengue, is caused by the bite of the Aedes mosquito.

7. Three new Exotic subatomic particles discovered with the Large Hadron Collider

Tags: Science and Technology

The Large Hadron Collider beauty (LHCb) experiment has  discovered three never-before-seen particles.

  • What is the discovery?

  • CERN, (European Organization for Nuclear Research) was investigating the slight differences between matter and antimatter by studying a type of particle called the “beauty quark”, or “b quark”.

  • The three “exotic” particles, a new kind of “pentaquark” and the first-ever pair of “tetraquarks” were found.

  • These are a kind of new hadrons.

  • The discovery will help physicists understand how quarks bind together in these composite particles.

  • What are Quarks?

  • Quark is a fundamental component of matter and is defined as an elementary particle.

  • These quarks combine to produce composite particles called hadrons.

  • They usually combine together in groups of twos and threes to form hadrons.

  • The most stable of these are neutrons and protons which are components of the atomic nucleus.

  • They can also combine into four-quark and five-quark particles, called tetraquarks and pentaquarks.

  • These exotic hadrons were predicted by theorists nearly six decades ago.

  • Tetraquarks and Pentaquarks

  • Atoms contain smaller particles called neutrons and protons, which are made up of three quarks each.

  • Most of the exotic hadrons discovered in the past two decades are tetraquarks or pentaquarks.

  • They contain a charm quark and a charm antiquark.
