needs of the African partners.
➢ Africa is the new “field of competition”. The eyes of developed and developing economies are
on the African region.

medium-term framework, with a strong anchor to public finances.

IMPORTANT DAYS AND DATES
NATIONAL SCIENCE DAY OBSERVED ON FEBRUARY 28TH
➢ India celebrates National Science Day on February 28.
National Science Day is celebrated in the country to mark the
discovery of the Raman Effect. Raman discovered the Raman
Effect on February 28, 1928, and received the Nobel Prize for
his discovery in 1930.
➢ History of National Science Day
➢ The National Council for Science and Technology 1986 proposed to mark National Science
Day on February 28. The Government of India agreed to the proposal.
➢ The objective of National Science Day
➢ National Science Day is celebrated to spread the importance of science in day-to-day life. On
this occasion, the importance of science and achievements in the field are discussed. New
technologies are implemented.
➢ The theme of National Science Day 2023: Global Science for Global well being
➢ Raman Effect
➢ The wavelength of light changes in the air as it is deflected by molecules. This is referred to as
scattering. The sky is blue in color because of the Raman effect.
➢ Smaller wavelengths scatter easily. The wavelength of blue is small and is scattered the
maximum as compared to all the other colors. For this reason, the sky is blue in color.
ZERO DISCRIMINATION DAY OBSERVED ON MARCH 1ST
➢ Zero Discrimination Day is celebrated on March 1. The day is
mainly celebrated by organizations like UNAIDS. The main objective
of the day is to promote equality.
➢ The first Zero Discrimination Day was celebrated in 2014. It was
launched by UNAIDS. The first Zero Discrimination Day
celebrations were conducted in Beijing.
➢ Zero Discrimination Day in India
➢ In India, activists use the day to speak against discrimination faced by the LGBT community.

yet taken any action on this.
➢ So internationally, the code hasn’t been repealed in India. In other former British colonies like
Singapore, the act has been completely repealed.
SCIENCE AND TECHNOLOGY
MOON DUST AS SOLAR SHIELD
➢ Recently, a team of Researchers have published a study titled- “Dust as a Solar Shield”,
proposing that launching Moon Dust into the stratosphere can slow down Global-Warming.
➢ What was the Proposal?
➢ Solar Radiation Management: They proposed the regular transport of moon dust to a gravity
point (Lagrange Point) between Earth and Sun to temper the ravages of global warming.
➢ Analogy with Volcanic Spew and Moon Dust: Artificially spraying Moon Dust into the
stratosphere has been motivated from the fact that a sufficiently powerful Volcanic Eruption
can spew sulfates and other aerosols into the stratosphere and thus cool the air there.
MOON, VENUS & JUPITER CONJUNCTION
➢ The Moon, Venus, and Jupiter are to come to the spot in the sky
on February 22, 2024. Moon will pass very close to Jupiter and
Venus immediately after sunset. You can watch this easily even
without a telescope. However, without the telescope, the planets will
appear like a star.
➢ What is a conjunction in astronomy?
➢ The conjunction occurs when two or more planets or two or more
moons pass close by. For instance, the sun and moon are in conjunction during new moon
days. Planetary conjunction occurs when two or more planets come close by.
➢ Magnitudes of Venus and Jupiter during the conjunction
➢ Venus will be at a magnitude of -4.0. Jupiter will be at a magnitude of -2.1. And the moon
will be at a magnitude of -9.8. Magnitude is the measure of brightness.
➢ Venus and Jupiter are the brightest planets in the solar system. Jupiter is the brightest for its size.
And Venus is the brightest for its gasses and thick clouds in the atmosphere that reflects most
of the sunlight back into space.
➢ Venus Jupiter conjunction
➢ The planets have at least one conjunction every year. However, the 2023 conjunction is
special and unique.
➢ Why so? Usually, the Venus-Jupiter conjunction occurs very close to the sun. The bright light
from the sun makes the conjunction invisible. However, this conjunction is a bit far away and
is clearly visible.
JAMES WEBB TELESCOPE SPOTS 6 MONSTER GALAXIES
➢ The James Webb Space Telescope (JWST) has discovered six
Monster galaxies, formed roughly 500-700 million years after the
Big Bang, according to a Study.
➢ How were these Galaxies Found?
➢ Researchers spotted the six monster galaxies using the Cosmic
Evolution Early 44 Release Science programme of JWST.
➢ The programme studies the formation of the earliest galaxies when the universe was less
than 5% of its current age.
➢ Researchers turned the telescope to a patch of the sky close to the Big Dipper, which appears
to harbor a group of stars that form a pattern in the night sky. The Hubble space telescope first
observed this region in the 1990s.
➢ The Big Dipper is an asterism of stars, in the constellation Ursa Major (also known as the
Great Bear). It consists of seven bright stars, four forming a rectangular "bowl" shape and three
forming a "handle".
➢ It is often used as a navigational tool, a reference point for stargazing, and as a symbol in popular
WHAT ARE NEUTRINOS?
➢ Recently, physicists working with the Kamioka Liquid Scintillator
Antineutrino Detector (KamLAND) in Japan reported that after
analyzing two years’ data, they could not find signs that neutrinos
could be their own anti-particles.
➢ What was the Experiment?
➢ KamLAND looks for an event called neutrinoless double beta-decay.
In normal double beta-decay, two neutrons in an atom turn into two protons by emitting
two electrons and two electron antineutrinos.
➢ In neutrinoless double beta-decay, the anti-neutrinos aren’t emitted, which can happen only if
anti-neutrinos are just different kinds of neutrinos.
➢ What are Neutrinos?
➢ Neutrinos are the second most abundant particles in the Universe after photons (light
particles), produced in copious amounts in the cores of stars.
➢ Properties: Because they are so ubiquitous, their properties are windows into the microscopic
structure of the universe.
➢ For example, one open question about neutrinos is whether they are their own antiparticles. If
they were, physicists will have a way to explain why the universe has more matter than
LADAKH SETS GUINNESS RECORD PANGONG TSO MARATHON
➢ The Ladakh Autonomous Hill Development Council recently launched the Pangong Tso
Marathon. The marathon is the first of its kind in India. It was held on
the frozen Pangong Tso lake.
➢ The marathon was conducted at an altitude of 4,350 meters. With
this, it makes the Guinness record for World’s Highest Frozen
Lake Marathon. It is the first frozen lake marathon in India.
➢ About the Marathon
➢ The marathon included a 21 km long run. It began in Luking village. The marathon was organized
by the Council of Ladakh along with the Adventure Sports Foundation of Ladakh.
➢ Pangong Tso Lake
➢ The lake has saline water and is completely frozen during winter. Researchers believe that the
lake was a part of the Indus river system in early times. Today, however, the lake lies
separated from the Indus river. It is the highest saltwater lake in the world.
WHAT IS DICKINSONIA FOSSILS?
➢ Fossils of an extinct species, Dickinsonia, that scientists reported in a discovery from India’s
Bhimbetka Rock Shelters in 2021 have been found to be a false alarm.
➢ Researchers after a closer look at the site revealed the Dickinsonia fossil to really be wax
smeared on a rock by a beehive.
➢ What is Dickinsonia?
➢ Dickinsonia is an extinct primitive animal that inhabited seabeds around Australia, China,
Russia, Ukraine, in the Ediacaran period, 600-500 million years ago.
➢ It was classified as an animal after the discovery of cholesterol molecules in the fossils. It is
believed to be one of the earliest animals to have existed on earth.
WHAT IS MAD COW DISEASE?
➢ Recently, Brazil has halted its beef exports to China after a case
of Mad Cow Disease was confirmed in the northern state of Para.
➢ What is Mad Cow Disease?
➢ Also known as Bovine Spongiform Encephalopathy (BSE) is
degenerative, transmissible, slowly progressive, and a fatal
infection that affects the central nervous system of adult cattle.
➢ Causes: BSE is caused by a protein called a prion normally found on cell surfaces, the normal
prion protein changes into an abnormal prion protein that is harmful.
➢ After getting altered, these proteins destroy the nervous system tissue-the brain and spinal cord.
➢ The body of a sick cow does not even know the abnormal prion is there. Without knowing
it is there, the cow’s body cannot fight off the disease.
