U.S. Air Force’s B-1B Lancer lands at Aero India 2023


The United States Air Force (USAF) has once again sent their B-1B Lancers and an array of other defence machinery to participate in the Aero Show 2023 held in Bengaluru.


What is B-1B Lancer?

  • B-1B Lancer, also known as ‘Bone’ (for B-one), carries the largest conventional payload of both guided and unguided weapons in the USAF.
    • It is considered the backbone of America’s long-range bomber force.
    • This is the second time that the long-range, supersonic, heavy bomber is participating in Aero India.
      • The aircraft performed a fly-by on the inaugural day of Aero India 2021, escorted by an Indian Air Force Tejas fighter.
  • The long-range, supersonic heavy bomber which is dubbed Bone (for “B-one”) carries the largest conventional payload of both guided and unguided weapons in the USAF.
    • Apart from the B-1s, the US lineup at the biennial air show includes the USAF’s newest fifth-generation fighters – the stealthy, supersonic, multirole F-35A Lightning II and F-35A Joint Strike Fighter. 
  • An F-16 Fighting Falcon duo has been conducting daily aerial demonstrations, while the US Navy F/A-18E and F/A-18F Super Hornet multirole fighters are on static display.


  • Strategic partnership: The return of the long-range, supersonic, heavy bomber to India to participate in Aero India 2023 underscores the importance the United States places on the growing strategic partnership with India.

India’s lithium discovery & environmental risks


Though the recent discovery of 5.9 million tonnes of inferred resources of lithium in Jammu & Kashmir, by the Geological Survey of India is a game-changer in India’s impending transition to a green economy. However, the development of these reserves needs to be conducted sustainably – both in terms of the environment and equity 


Why is the finding a big deal?

  • Usage: The soft, shiny grey metal is an extremely important one in today’s world. It is used, among other things, to build the batteries that electric vehicles cannot do without. Hence the name ‘white gold’.
  • Self-reliance in the LIB [lithium-ion battery]: If India has its own sources of lithium, it would not have to rely too much on imports for its lithium needs, as it currently does.
    • In 2020-21, India imported Rs 173 crore worth of lithium and Rs 8,811 crore worth of lithium ions. India’s lithium needs are also likely to rise, given the push for electric vehicles.
  • Rare: Lithium reserves are also rare.
    • There are 98 million tonnes of lithium globally, said Rishabh Jain, senior programme lead, Council on Energy, Environment and Water (CEEW). Now India has found 5.5% of these resources

As per one estimate, Chile – at 9.2 million tonnes – led the world in lithium reserves, followed by Australia (6.2 million tonnes). So India’s recent find of 5.9 million tonnes of lithium could catapult it into the top three countries in the world with the highest lithium reserves.

Impact on Environment

  • Water-intensive: The process of extracting lithium from its ore is also extremely water-intensive; as per one estimate, it takes approximately 2.2 million litres of water to produce one ton of lithium. And the demand for lithium is only increasing. 
  • Extensive mining: Extracting Li from hard rock mines entails open-pit mining followed by roasting the ore using fossil fuels.

MicroLED Technology


Apple is currently working on shifting to microLED display technology and plans to implement the same on future watch models starting in 2024.


What is microLED display technology?

  • The basis of microLED technology is sapphires. A sapphire can shine on its own forever. A microLED screen is filled with such small but strong light.
  • The picture in a microLED screen is generated by several individual light-emitting diodes.
  • A microLED is as small as cutting a centimetre of hair into 200 smaller pieces. Each of these micro LEDs is a semiconductor that receives electric signals.
  • Once these micro LEDs are gathered, they form a module. Several modules are then combined to form screens.

  • MicroLED displays are brighter, have better colour reproduction and provide better viewing angles.
  • MicroLEDs have limitless scalability, as they are resolution-free, bezel-free, ratio-free, and even size-free.
  • The screen can be freely resized in any form for practical usage.

DHARA 2023

DHARA which stands for Driving Holistic Action for Urban Rivers, the annual meeting of the members of the River Cities Alliance (RCA) was recently organised by the National Mission for Clean Ganga (NMCG) in association with National Institute of Urban Affairs (NIUA) in Pune.

About River Cities Alliance (RCA) 

  • Launched in: 2021
  • Objective:to provide the member cities with a platform to discuss and exchange information on aspects that are vital for sustainable management of urban rivers, sharing best practices and supporting innovation.
  • The Alliance is open to all river cities of India. Any river city can join the Alliance at any time.
  • River Cities Alliance (RCA) started with 30 cities in 2021 and currently has 95 cities as members across India.

Elusive Dark Galaxy Revealed By ALMA Telescope Observation

A team of researchers recently used the Atacama Large Millimetre/Submillimeter Array (ALMA) to detect an elusive black galaxy, dubbed 'invisible galaxy'.


  • It is "compact, and containing large quantities of interstellar dust, it is a young galaxy, forming stars at about 1000 times the rate of the Milky Way."

What is ALMA?

  • Location: Chile
  • It is a state-of-the-art telescope to study light from some of the coldest objects in the Universe.
  • This light has wavelengths of around a millimetre, between infrared light and radio waves, and is therefore known as millimetre and submillimetre radiation.
  • ALMA is a single telescope of revolutionary design, composed initially of 66 high-precision antennas, and operating at wavelengths of 0.32 to 3.6 mm.

Diyodar meteorite: India’s first aubrite in 170 years

In 2022, a meteorite streaked over India, breaking apart as it descended through the air, to scatter over two villages in Banaskantha, Gujarat. In an analysis, it has been revealed that the meteorite was a “rare, unique specimen” of aubrite.

What are Aubrites?

  • Aubrites“are coarse-grained igneous rocks that formed” in oxygen-poor conditions, and thus “contain a variety of exotic minerals that are not found on Earth”.
    • For example, the mineral heideite was first described in the Basti meteorite.
  • Worldwide, aubrites have crashed in at least 12 locations since 1836, including three in Africa and six in the U.S.


Shaping A More Disabled-Friendly Digital Ecosystem


While technology has enormous potential to level the playing field for the disabled, it can, at the same time, reinforce the barriers that the disabled otherwise face if it is not designed with their needs in mind.

Factbook on Disabled people:

  • India: According to Census 2011, 2.21% of India’s population is disabled is a gross underestimation.
  • World: According to the World Health Organization, about 16% of the global population is disabled.
  • Extrapolation According to India: If that figure is extrapolated to the Indian context, it would mean at least 192 million disabled people.
