5. Bioenergy Crops:
According to a new study, converting annual crops to perennial bioenergy crops can induce a cooling effect on the areas where they are cultivated.
• Bioenergy crops include specific plants that are grown and maintained at lower costs for biofuel production.
• Biofuel generation using fast growing and photosynthetically efficient bioenergy crops is emerging as a reliable alternative to fossil fuels.
• Bioenergy crops are one such energy source that could positively impact the environment to reduce the level of carbon dioxide, emission of greenhouse gases and soil erosion.
• These crops increase soil carbon and fix atmospheric carbon. They could be used for the phyto-remediation of heavy metal-contaminated soils.
• Bioenergy crops are classified into five types namely,
1. First-generation bioenergy crops - Corn, sorghum, rapeseed and sugarcane
2. Second-generation bioenergy crops - Switchgrass, miscanthus, alfalfa, reed canary grass, Napier grass and other plants.
3. Third-generation bioenergy crops - Boreal plants, crassulacean acid metabolism (CAM) plants, eucalyptus and microalgae.
4. Bioenergy halophytes - Genera Acacia, Eucalyptus, Casuarina, Melaleuca, Prosopis, Rhizophora and Tamarix.
5. Dedicated energy crops - Perennial herbaceous and woody plant species as giant miscanthus, switchgrass, jatropha and algae.
4. Dark Genome:
Scientists investigating the ‘dark genome’ have discovered recently evolved regions that code for proteins associated with schizophrenia and bipolar disorder.
• Dark genome - Human genome is conventionally divided into,
1. Coding genome, which generates the ~20,000 annotated human protein coding genes, and
2. Dark genome, which does not encode proteins.
• Dark genome is a vast space, accounting for the ~98.5% of genomic space where repeat elements, enhancers, regulatory sequences, and non-coding RNAs reside.
• It comprises the DNA outside our genes. These are the regions, not classed as genes in the traditional sense, which create proteins.
• Study - The scientists say that these new proteins can be used as biological indicators to distinguish between the two conditions - schizophrenia and bipolar disorder.
• It can also be used to identify patients more prone to psychosis or suicide.
3. Muscle Dysfunction and Vitamin D:
A new study has examined the molecular nature of muscle dysfunction in the absence of vitamin D.
• Usually, the glucose absorbed from the food is converted into glycogen and stored in the skeletal muscle.
• This stored energy reserve is used by muscles to produce energy after the food consumed is digested.
• Without the vitamin D, the skeletal muscles continued to make glycogen, but could not convert them into glucose (usable form of energy).
• When the glycogen storage does not give energy, particularly in a post-absorb state, the skeletal muscle draws more glucose from the blood. This leads to a systemic energy shortage.
• When there is systemic lack of energy, the protein degradation in muscle is triggered leading to muscle wasting.
• This shows that vitamin D deficiency starves the skeletal muscles, leading to muscle wasting.
Functions of Vitamin D:
• Vitamin D works more as a hormone than and is involved in a host of biochemical reactions.
• It is key to maintaining metabolic functions, immune system, bone health and plays a crucial role in depression, mood swings, anxiety and sleep quality.
• As part of the normal metabolic process, proteins produced in our body degrade, and in due course, new proteins are made to replace them.
• Usually, when the protein degradation exceeds protein synthesis, skeletal muscle atrophy or simply a decrease in muscle mass occurs. This is what happens during Vitamin D deficiency.
2. Black Hole ignites Star Formation:
NASA's Hubble Space Telescope finds a black hole igniting star formation in a dwarf galaxy.
• Often portrayed as destructive monsters that hold light captive, a black hole at the heart of the dwarf galaxy Henize is creating stars rather than gobbling them up.
• The black hole is apparently contributing to the firestorm of new star formation taking place in the galaxy.
• Outflow of gas - An outflow of gas from the black hole stretches across space like an umbilical cord to a bright stellar region that is located 230 light-years from the black hole.
More massive the host galaxy, more massive the black hole at its centre.
Target Prelims-cum-mains 2023:
1. The Challenge of Antimicrobial Resistance:
The Global Research on Antimicrobial Resistance (GRAM) report was published in the Lancet recently providing the most comprehensive estimate of the global impact of AMR.
• Antimicrobial resistance (AMR) is the ability of a microbe to resist the effects of medication previously used to treat them.
• Resistant microbes are more difficult to treat, requiring alternative medications or higher doses, both of which may be more expensive or more toxic.
• Microbes resistant to multiple antimicrobials are called Multi Drug Resistant (MDR) or sometimes Superbugs.
Prominent causes:
• Usage- There is an increasing use of antibiotics for human and veterinary purposes in the recent period.
• There is irrational consumption(over usage) of broad spectrum antibiotics.
• In India, effluents generated from these industries are treated as per the pharmaceutical wastewater discharge guidelines as prescribed by the Central Pollution Control Board.
• But the current standards do not include antibiotic residues, and they are not monitored in the pharmaceutical industry effluents.
• The existing good manufacturing practices (GMP) under the WHO (2016) framework is restricted to drug safety alone and does not recognise the environmental risk with pharmaceuticals products.
• Waste Discharge- The uncontrolled discharge of untreated urban waste is another major source for AMR in many low and middle income countries.

5. Aquamation:
• It is a green alternative to traditional cremation methods.
• It also known as alkaline hydrolysis and defined as “flameless cremation”.
• In this process the body is immersed for a few hours in a mixture of water and a strong alkali in a pressurized metal cylinder and heated to around 150 degrees centigrade.
• The combination of gentle water flow, temperature and alkalinity accentuate the breakdown of the organic
materials. The process leaves behind bone fragments and a neutral liquid called effluent.
• The effluent is sterile, and contains salts, sugars, amino acids and peptides.
• There is no tissue and no DNA left after the process completes
• The process was developed and patented in 1888 by Amos Herbert Hanson, a farmer who was trying to develop an ingenious way to make fertilizer from animal carcasses.
• This process uses energy which is five times less than fire. It also reduces by about 35% the amount of
greenhouse gases that are emitted during other ways of cremation.
4. Chemical weapons:
• Chemical weapons are weapons and other equipment that use the toxic effects of chemicals on living organisms to cause death or other harm.
• To qualify as a chemical weapon, the toxic effects of warheads must not necessarily be fatal.
• Chemical weapons are considered weapons of mass destruction, as toxic chemicals can spread over large areas and affect large numbers of people.
International Law regarding Use of Chemical Weapons:
• Chemical Weapons Convention (CWC) is a multilateral treaty banning chemical weapons and requiring
their destruction within the stipulated time.
• Negotiations for the CWC began in 1980 at the United Nations Conference on Disarmament.
• The convention was opened for signature in January 1993. It became effective from April 1997.
• Members should also declare the riot-control agents (tear gas) in possession of them.
• India signed the treaty in January 1993. The Chemical Weapons Convention Act, 2000 was passed to
implement the CWC.
• Apart from CWC, Australia Group seeks to check proliferation of chemical or biological weapons. India
joined (as 43rd Participant) the Australia Group (AG) in January 2018.
## Russia accused of attack on Ukraine using illegal phosphorus bombs.
• International law prohibits the use of white phosphorus shells in heavily populated civilian areas but allows them in open spaces to be used as cover for troops.
• White phosphorous is used in fumes, lights and incendiary warships, and is usually the burning element of
tracer ammunition.
• It is pyrophoric which mean it ignites on contact with air, burns fiercely and can ignite clothing, fuel,
ammunition and other flammable materials.
3. Blue Straggler Stars:
##Indian Institute of Astrophysics, Bengaluru conducted a study on the aberrant behaviour of Blue Straggler Stars.
#The researchers made use of the observations by the UVIT instrument (Ultraviolet Imaging Telescope) of Astrosat, India’s first science observatory in space.
About Blue Straggler Stars:
• It is a class of stars on open or globular clusters that stand out as they are bigger and bluer than the rest of
the stars.
• These stars tend to be strongly concentrated toward the centre of the cluster.
• These stars are seen in clusters and sometimes alone.
2. Solid Fuel Ducted Ramjet (SFDR) Technology:
The DRDO successfully conducted a flight trial of the SFDR booster.
About SFDR
• It is jointly developed by India and Russia.
• It is a missile propulsion system consisting of a thrust modulated ducted rocket with a low smoke nozzleless
missile booster.
• Thrust modulation in the system is achieved by using a hot gas flow controller.
• SFDR-based propulsion enables the missile to intercept aerial threats at very long ranges at supersonic
speeds.
• This type of propulsion system significantly increases the range with a higher average speed.
• Missiles using such a system are also capable of carrying large payloads due to the absence of oxidizer.
• Unlike solid-propellant rocket, the Ramjet takes up oxygen from the atmosphere during flight.
➢ At present lot of conventional missiles uses booster or sustainer configuration with solid or liquid
propellants, which have limitations against manoeuvring target.
➢ This is because terminal stage of conventional missiles cannot provide enough energy to maintain their
speed in order to hit targets.
##SDFR technology removes this drawback by exceptionally enhancing
endgame manoeuvrability of missile at terminal stage when its seeker is locked onto target.

1. India’s Step To Tackle Space Debris:
• ISRO initiated ‘Project NETRA’ in Bengaluru.
• It is an early warning system in space to detect debris and other hazards to Indian satellites.
• It will give India its own capability in space situational awareness (SSA), which is used to ‘predict’ threats
from debris to Indian satellites.
• It also goes so far as to serve as an unstated warning against missile or space attack for the country.
Kessler Syndrome: It is a possible effect that if one satellite produces debris that hit another satellite, this will
create a chain reaction that will obliterate every orbiting object in the Low Earth Orbit, and thus creating a
thick cloud of white dots travelling at high speed. Rockets would no longer be able to reach space since they
risk getting hit by these debris.
