Indian Institute of Science (IISc) researchers have designed a novel ultramicro supercapacitor, capable of storing an enormous amount of electric charge.

  • Energy storage devices - Batteries that currently power most of these devices lose storing ability over time.
  • Capacitors, while storing electric charge for much longer, cannot discharge energy constantly.
  • Supercapacitors overcomes these shortfalls by combining the properties of capacitors and batteries into one device.
  • Supercapacitors - Supercapacitors are electronic devices which are used to store extremely large amounts of electrical charge.
  • Supercapacitors are also known as double-layered capacitor or ultracapacitor.
  • Supercapacitors come with capabilities to store and release large amounts of energy, making them highly sought-after for next-generation electronic devices
  • The novel ultra-micro supercapacitor is smaller and more compact than existing supercapacitors.
  • They can potentially be used in devices ranging from streetlights to consumer electronics, electric cars and medical devices.

Classes of Solar Flare

The Sun sent out a powerful ‘X-class’ solar flare on March 29, 2023 which was classified as an X1.2 flare.

  • The X1.2 flare erupted from sunspot AR3256 near the south-western limb of the star in our Solar System.
  • This solar flare led to a strong shortwave radio blackout over south-east Asia, Australia, and New Zealand.
  • Solar Flare - A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots.
  • They are seen as bright areas on the sun and they can last from minutes to hours.
  • There are 4 classes of solar flares - B, C, M and X.
  • Solar flares are classified on a logarithmic scale similar to the Richter scale.
  • This means that a C-class storm is 10 times more powerful than a B-class storm and so on.
  • The class denotes the strength of the flare and the number that comes after it signifies their strength at a finer scale.
  • Each class is therefore divided into 9 subdivisions.
  • For example, X1 to X9.
  • Flares and solar eruptions can impact radio communications, electric power grids, and navigation signals, and pose risks to spacecraft and astronauts.
  • X-class flares can trigger planet-wide radio blackouts and long-lasting radiation storms.


  1. IE - Powerful ‘X-class’ solar flare slams Earth, causes radio blackouts
  2. NASA - Strong Solar Flare Erupts from Sun
  3. India Today - Powerful flare from Sun hits Earth

Moon to Mars Program Office

NASA has set up a new Moon to Mars Program Office at its headquarters in Washington.

  • The Moon to Mars Program Office will help prepare NASA’s human spaceflight missions to the Moon and beyond.
  •  The office will also help NASA to set up a long-term presence of human on the Moon.
  • The office will focus on hardware development, mission integration, and risk management for programs that will be critical to NASA’s space exploration approach.
  • It will also lead the planning and analysis for developments to support human Mars mission.
  • New Head - Amit Kshatriya will serve as the agency’s first head of the new office.
  • He earlier served as acting deputy associate administrator for the agency’s Common Exploration Development.

NASA aims to send astronauts to Mars by the late 2030s or early 2040s.


  1. IE - NASA sets up new office to help land humans on Mars
  2. IE - Amit Kshatriya is the head of new Moon to Mars Program Office
  3. NASA - New Program Office Leads NASA’s Path Forward for Moon, Mars

Tajikistan and Azerbaijan declared Malaria free

The World Health Organization (WHO) has certified Azerbaijan and Tajikistan as malaria-free.

  • In the latest announcement, the WHO officially declared 41 countries and one territory, including 21 countries in the European Region, malaria-free.
  • Azerbaijan and Tajikistan were certified as malaria-free for eliminating the Anopheles mosquito-borne disease in their territories.
  • In Tajikistan and Azerbaijan, the last cases of regional spread of Plasmodium vivax malaria were discovered in 2012 and 2014, respectively.
  • Certification - Certification of malaria elimination is the official recognition by WHO of a country’s malaria-free status.
  • WHO grants this certification when
    • A country has proven that the chain of local transmission by Anopheles mosquitoes has been interrupted nationwide for at least the past 3 consecutive years.
    • A country must also demonstrate the capacity to prevent the re-establishment of transmission.
  • A fully functional surveillance and response system that can prevent re-establishment of indigenous transmission is in place.



Malaria is a disease caused by a Plasmodium parasite


It is usually transmitted by the bite of infected female Anopheles mosquitoes.


The severity of malaria varies based on the species of Plasmodium - Plasmodium falciparum and Plasmodium vivax are fatal.


Symptoms of the disease includes chills, fever and sweating, usually occurring a few weeks after being bitten.


It is both preventable and curable.


Mosquirix is the first and to date only vaccine shown to have the capability of significantly reducing malaria.

Measures & initiatives  India

  • National Malaria Eradication Programme (NMEP) - 1958
  • National Vector Borne Disease Control Programme (NVBDCP) - 2003
  • National Framework for Malaria Elimination in India 2016–2030
