Researchers have traced the paleoclimatic history of the Indus River in Ladakh Himalaya with the help of geometric data from overlapping gravels of channel fills. They studied the discharge during periods in which the river experienced an increase in land elevation, due to the deposition of sediment) and its incision.
River Terraces are ubiquitous in mountains that nourish and help sustain past, present, and future human societies. These terraces are part of valley-wide aggradations, which has been studied extensively in Himalaya to understand the processes driving such a periodic increase in river valley land elevation and incision. Scientists are still debating whether wetter climate intervals with increased rainfall and glacial melting promote river aggradation through increased discharge and enhanced sediment load, or instead, is it during drier conditions when aggradation occurs through increased sediment to water ratio.
The researchers observed that the aggradation in the Himalayan rivers occurred in glacial-interglacial transient warm climatic conditions (33–21 ka and 17–14 ka) when the sediment budget in the rivers increased just after the glacial events.
Aggradation took place in the Indus River when sediment to water ratio was higher during MIS-3 (Marine isotope stages (MIS), marine oxygen-isotope stages, are alternating warm and cool periods in the Earth's paleoclimate, deduced from oxygen isotope data reflecting changes in temperature derived from data from deep-sea core samples) and incision initiated when sediment to water ratio reduced during post-glacial climatically wet phase (early Holocene).

(Topic: World History)
The Korean War was a war between North Korea (with the support of China and the Soviet Union) and South Korea (with the support of the United Nations, principally from the United States). The war began on 25 June 1950 when North Korea invaded South Korea.
At the end of World War II, the Soviet Union and the United States liberated Korea from imperial Japanese colonial control on 15 August 1945. After the war had ended, Korea was divided at the 38th parallel into two zones of occupation, the Soviets administered the northern half and the Americans administered the southern half. With the border set at the 38th parallel in 1948, two sovereign states were established as a result of geopolitical tensions of the Cold War (between the Soviet Union and the United States). A socialist state was established in the north under the communist leadership of Kim Il-sung and a capitalist state in the south under the anti-communist leadership of Syngman Rhee. Both governments of the two new Korean states claimed to be the sole legitimate government of all of Korea, and neither accepted the border as permanent.
The conflict escalated into warfare when North Korean military (Korean People's Army, KPA) forces—supported by the Soviet Union and China—crossed the border and advanced into South Korea on 25 June 1950. The United Nations Security Council authorized the formation of the United Nations Command and the dispatch of forces to Korea to repel what was recognized as a North Korean invasion. Twenty-one countries of the United Nations eventually contributed to the UN force, with the United States providing around 90% of the military personnel
What factors led to the division of Korea into South and North Korea?
The Division of Korea began at the end of World War II in 1945. With the defeat of Japan, the Soviet Union occupied the north of Korea, and the United States occupied the south, with the boundary between their zones being the 38th parallel.
Japanese Rule: Since Russio-Japanese war ended in 1905, Korea was under Japanese control till 1945. During this period, nationalist and radical groups emerged, mostly in exile, to struggle for independence.
World War II and defeat of Japan: As war began, Russia took benefit of resentment rising in Korea against Japanese rule. Russia called on Koreans to rise up against Japan. US became anxious that Russia would occupy the whole of Korea, thus they hurriedly decide on the south of 38th parallel as American occupation. They chose it because it divided the country approximately in half but would place the capital Seoul under American control. During the process no one from Korea were consulted.
Cold war: Soon after WWII, cold war between US and USSR started. USSR started to establish communism in Northern part of Korean peninsula. With the fear of Soviet expansion, US occupied South Korea and established anti-communist government there.
UN intervention and the formation of separate governments: UN decided to hold elections in Korea to establish an independent government there, but Soviet Union boycotted the elections because it was perceived that UN is under US influence. Therefore UN decided to go-ahead with election only in South. The decision to proceed with separate elections was unpopular among many Koreans, who rightly saw it as a prelude to a permanent division of the country.
Korean War: It was final nail in the coffin of United Korea. In 1950, North Korea invaded South Korea. United Nations intervened to protect the South, sending a US-led force. Both the sides tried to unify Korea under their influence, communist and anti-communist.
Armistice: The Korean Armistice Agreement was signed after three years of war. The two sides agreed to create a four-kilometer-wide buffer zone between the states, known as the Korean Demilitarized Zone (DMZ). This new border, reflecting the territory held by each side at the end of the war, crossed the 38th parallel diagonally. And Korea stood formally divided.

Electricity is one of the most critical components of infrastructure which is essential for sustained growth of the economy of the country. While we have made significant improvements in the electricity generation and transmission segments, the distribution segment, having achieved 100% village electrification and near-universal access to electricity, is beset with problems of operational inefficiencies, liquidity, and financial solvency.
Proposed power reforms are aimed at introducing transparency and accountability to protect the interest of consumers and ensuring healthy growth of the power sector.
There is no restrictions on States for providing subsidy as States can give as much subsidy as they want but they must pay it upfront through Direct Benefit Transfer(DBT) so that Discoms remain healthy and are able to maintain and improve distribution infrastructure like transformers and distribution lines, pay for power purchased and are able to provide quality electricity to the people.

Under the Emergency Credit Line backed by a Government guarantee, Banks from Public & Private Sectors have so far already sanctioned loans worth over Rs. 79,000 crore as of June 20, 2020, of which more than Rs. 35,000 crore has already been disbursed.
The top lenders under the scheme are SBI, HDFC Bank, Bank of Baroda, PNB & Canara Bank. This has helped 19 lakh MSMEs & other businesses restart their businesses post the lockdown.
As part of the Aatmanirbhar package, Government had announced its plans for Rs. 3 lakh crore as additional credit to MSMEs and small businesses. Such enterprises were to be eligible to receive upto 20% of their existing borrowing as additional loans at interest rates which were capped.
Separately, under RBI’s Special Liquidity Facility announced in March-April, 2020, SIDBI has sanctioned over Rs. 10,220 crore to NBFCs, Micro Finance Institutions & Banks for lending to MSME& small borrowers. National Housing Bank (NHB) has sanctioned its entire facility of Rs. 10,000 crore to Housing Finance Companies. This refinance by SIDBI & NHB is in addition to ongoing schemes through which over Rs. 30,000 crore has been sanctioned. NBFCs & MFIs are being further helped under the Extended Partial Guarantee Scheme where approvals have crossed Rs. 5500 crore. Transactions for another Rs. 5000 crore are under process of approval while certain other deals are currently under negotiation.
(Topic: Animal Husbandry)
Government had earlier approved the Dairy Infrastructure Development Fund (DIDF) worth Rs. 10,000 crores for incentivizing investment by cooperative sector for development of dairy infrastructure. However, the MSMEs and Private companies also need to be promoted and incentivized for their participation in processing and value addition infrastructure in the animal husbandry sector. The Animal Husbandry Infrastructure Development Fund (AHIDF) approved would incentive infrastructure investments in dairy, meat processing and animal feed plants.
The AHIDF with the interest subvention scheme for private investors will ensure availability of capital to meet upfront investment required for these projects and also help enhance overall returns/ pay back for investors. Such investments in processing and value addition infrastructure by eligible beneficiaries would also promote exports.
Since almost 50-60% of the final value of dairy output in India flows back to farmers, the growth in this sector can have significant direct impact on farmer’s income. Size of dairy market and farmers’ realization from milk sales is closely linked with development of organized off-take by cooperative and private dairies. Thus, investment of Rs. 15,000 crores through AHIDF would not only leverage several times more private investment but would also motivate farmers to invest more on inputs thereby driving higher productivity leading to increase in farmers income. The measures approved today through AHIDF would also help in direct and indirect livelihood creation for about 35 lakh persons.
(Topic: Climate Change)
The National Centre of Polar and Ocean Research (NCPOR) has found a dramatic decline in the Arctic sea ice due to global warming. The decline of sea ice has led to localized increase in evaporation, air humidity, cloud cover, and rainfall.
Arctic sea ice is a sensitive indicator of climate change and has strong retaliatory effects on other components of the climate system.
The largest decline in Arctic sea ice in the past 41 years happened in July 2019. In the last 40 years (1979-2018), the sea ice has been declining at a rate of ‘-4.7%’ per decade, while its rate was found to be ‘-13%’ in July 2019. If this trend continues, there would be no ice left in the Arctic sea by 2050, which would be dangerous for humanity and the entire environment.
(Topic: Climate Change)
A study of a microscopic ancient marine algae (Coccolithophores) led by the National Centre for Polar and Ocean Research (NCPOR) has found that there is a decrease in the concentration of oceanic calcium carbonate (CaCO3) in the Southern Indian ocean.
This decrease in CaCO3 is attributed to the increase in the concentration of another single-celled algae known as diatoms. This, in turn, will affect the growth and skeleton structure of coccolithophores, with potential significance for the world ocean ecosystem.
Coccolithophores are single-celled algae living in the upper layers of the world's oceans.
Why is the study important: The results of the study point to climate change as a major reason for the altered coccolithophore calcification rate. Different environmental factors and the ability of the species to adapt to those environmental changes would ultimately determine the future coccolithophore calcite production. These investigations are important for future intervention to bring positive changes in the marine ecosystem and global carbon cycle.

Study showing stars of varied ages can co-exist in open clusters, provides clue to stellar evolution in the Milky Way Galaxy
Stars in our Galaxy are formed from the molecular clouds present in the Galaxy. It is believed that the majority of stars in our Galaxy are formed in the star clusters making them important clues to understand the star formation mechanism. Open star clusters are a system of stars bound by gravity in which stars are born from the same molecular clouds. All the stars in a cluster follow the evolutionary sequence as per their initial masses at the time of formation of these stars. Open clusters are also important in probing formation and evolution of Milky Way Galaxy as they are distributed throughout the Galactic disk.
Detection of fluorine in hot Extreme Helium Stars solves their evolution mystery
An extreme helium star or EHe is a low-mass supergiant that is almost devoid of hydrogen, the most common chemical element of the universe. There are 21 of them detected so far in our galaxy. The origin and evolution of these Hydrogen deficient objects have been shrouded in mystery. Their severe chemical peculiarities challenge the theory of well-accepted stellar evolution as the observed chemical composition of these stars do not match with that predicted for low mass evolved stars.
A study by the Indian Institute of Astrophysics (IIA) an autonomous institute of Department of Science and Technology which detected the presence of singly ionised fluorine for the first time in the atmospheres of hot Extreme Helium Stars makes a strong case that the main formation of these objects involves a merger of a carbon-oxygen (CO) and a Helium (He) white dwarf.

Study of optical properties of super-massive black-hole can provide clue to emission mechanism from its close vicinity
Through 153 nights, 17 scientists from 9 countries in Europe and Asia including researchers from Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, an autonomous institution of the Department of Science and Technology (DST), Government of India took 2263 image frames and observed the changes in a very high energy gamma-ray emitting blazar ‘1ES 0806+524’ using seven optical telescopes in Europe and Asia.
A blazar is a feeding super-massive black-hole (SMBH) in the heart of a distant galaxy that produces a high-energy jet viewed face-on from Earth. Blazars are one of the most luminous and energetic objects in the known universe with a jet composed of ionized matter traveling at nearly the speed of light directed very nearly towards an observer.
The large flares are the result of propagation of a shock in the relativistic jet that accelerates electrons to high energies followed by subsequent cooling. According to their study, the small amplitude changes can be understood to arise from small variations in the viewing angle, and hence in the Doppler factor, caused by either wiggling or helical jets or the motion of the most intense emitting region on a roughly helical trajectory within the jet. Variations on intra-day timescales can be explained by the turbulence expected in a relativistic plasma jet according to the study.
Blazars are among one of the most favourite astronomical transient objects because they emit radiation in the complete EM spectrum, and their flux and polarization are highly variable.

Leishmaniasis is a neglected tropical disease affecting almost 100 countries including India. It is caused by a parasite called Leishmania, which is transmitted through the bite of sand flies.
There are three main forms of leishmaniasis –
Visceral leishmaniasis, which is commonly known as Kala-azar in India, is fatal in over 95% of the cases, if left untreated. The only drug available against leishmaniasis, miltefosine, is rapidly losing its effectiveness because of emerging resistance to this drug due to a decrease in its accumulation inside the parasite, which is necessary for the drug to kill the parasite.
