Piezoelectric Effect in Liquids

Recently, scientists observed evidence of the piezoelectric effect in liquids for the first time.

Samudrayaan Mission

In a written reply to a question in Lok Sabha on December 21, 2022, Union Minister of State (Independent Charge) Science & Technology Dr. Jitendra Singh informed that Samudrayaan mission is expected to be realised by year 2026.

​TiHAN Testbed for Autonomous Navigation

The TiHAN Testbed for Autonomous Navigation was recently inaugurated at IIT Hyderabad.

  • It is a unique, first of its kind, futuristic "autonomous navigation” facility to develop unmanned ground and aerial vehicles.

Solid Adsorbents for CO2 Capture and Utilization

Recently, Indian scientists have discovered a novel strategy to synthesize novel solid adsorbents for CO2 capture and utilization.


  • Carbon capture and utilization are growing fields of research focusing on reducing CO2 emissions. Despite several industrial advancements having been already demonstrated, none of the technologies can provide an economically viable and complete CO2 capture and utilization solution. Therefore, fundamental research on novel solid adsorbents might offer a critical material for CO2 capture and utilization.

Mars Orbiter Spots Water in Mars’ Canyon System

The Roscosmos ExoMars Trace Gas Orbiter - a Mars orbiter launched in 2016 - has spotted water in Mars’ canyon system called the Valles Marineris.

  • Mission: It is a joint mission of the European Space Agency (ESA) and the Russian space agency Roscosmos.

Supersonic Missile Assisted Torpedo System Gets Successfully Launched From Wheeler Island in Odisha

On 13th December, 2021, the supersonic missile assisted torpedo system – developed by the Defence Research and Development Organisation (DRDO) - was successfully launched from Wheeler Island in Odisha.

  • The system is a next generation missile-based standoff torpedo delivery system.

Nobel Prize in Chemistry 2021

Benjamin List (Germany) and David W.C. MacMillan (USA) were announced joint winners of Nobel Prize in Chemistry 2021 “for the development of asymmetric organocatalysis”.


  • The type of catalysis developed independently by Benjamin List and David MacMillan, called organocatalysis, uses small organic molecules that are generally both environmentally friendly and inexpensive to produce. The use of organocatalysts has rapidly expanded since 2000. This is largely due to their ability to drive asymmetric synthesis.

Indian Scientists develop Carbon-based Wrapper for preserving Fruits

Indian researchers led by Dr. P. S Vijayakumar from Institute of Nano Science and Technology, Mohali have developed a composite paper made of carbon (graphene oxide) loaded with preservatives that can be used as wrappers to help extend shelf life of fruits.

India's First Earthquake Early Warning Mobile App

India's first early warning mobile application which can alert users before an earthquake was recently launched in Uttarakhand.

Indian Scientists Develop Self-Healing Materials

Researchers from the Indian Institute of Science Education and Research (IISER) Kolkata, teaming up with IIT Kharagpur, have developed piezoelectric molecular crystals that repair themselves from mechanical damages without need for any external intervention.
