How does the Rhisotope Project exemplify the use of science and technology in wildlife conservation efforts?
Discuss the potential applications of mRNA technology beyond COVID-19, with reference to its role in tackling emerging infectious diseases.
Introduction
— The introduction of the answer is essential and should be restricted to 3-5 lines. Remember, a one-liner is not a standard introduction.
— It may consist of basic information by giving some definitions from the trusted source and authentic facts.
Body
— It is the central part of the answer and one should understand the demand of the question to provide rich content.
— The answer must be preferably written as a mix of points and short paragraphs rather than using long paragraphs or just points.
— Using facts from authentic government sources makes your answer more comprehensive. Analysis is important based on the demand of the question, but do not over analyse.
— Underlining keywords gives you an edge over other candidates and enhances presentation of the answer.
— Using flowcharts/tree-diagram in the answers saves much time and boosts your score. However, it should be used logically and only where it is required.
Way forward/ conclusion
— The ending of the answer should be on a positive note and it should have a forward-looking approach. However, if you feel that an important problem must be highlighted, you may add it in your conclusion. Try not to repeat any point from body or introduction.
— You may use the findings of reports or surveys conducted at national and international levels, quotes etc. in your answers.
Self Evaluation
— It is the most important part of our Mains answer writing practice. UPSC Essentials will provide some guiding points or ideas as a thought process that will help you to evaluate your answers.
QUESTION 1: How does the Rhisotope Project exemplify the use of science and technology in wildlife conservation efforts?
Note: This is not a model answer. It only provides you with thought process which you may incorporate into the answers.
Introduction:
— Recently, a South African university launched an anti-poaching campaign with a unique approach – injecting radioactive isotopes into rhino horns. It claimed that the method is harmless for the rhinos and allows customs agents to detect trafficked horns.
— The Rhisotope Project is supported by the International Atomic Energy Agency (IAEA).
Body:
You may incorporate some of the following points in your answer:
— According to the IAEA, radioactive isotopes, or radioisotopes, are unstable forms of an element that emit radiation in order to transition into a more stable state. The radiation can be identified and usually produces changes in the substance it strikes.
— Rhino horns are tagged with tiny amounts of radioactive isotopes via a non-invasive method, allowing them to be detected by radiation portal monitors (RPMs), which are already deployed at borders, ports, and airports across the world to identify unauthorised nuclear items.
— To test this method, the researchers employed 3D-printed rhino horns that had the same shielding capabilities as actual keratin, the component that makes up rhino horn. According to the university, the examinations proved the presence of individual horns inside whole 40-foot shipping containers. According to the researchers, the process has proven to be harmless to rhinos while rendering the horn 'useless' and 'poisonous' for people.
— The technique is absolutely safe for the animal and effectively detects the horn using international customs nuclear security systems.
Conclusion:
— The International Union for Conservation of Nature estimated that the global rhino population was at 500,000 at the beginning of the twentieth century. It has since dropped to 27,000 due to the growing demand for rhino horns. These horns are smuggled to Asian markets, where they are utilised both in traditional medicine and as a prestige symbol. South Africa, home to the world's largest rhino population, has lost almost 10,000 rhinos to poaching in the last decade.
— The project itself is not a cure-all or silver bullet to curb poaching, the researchers hope it will prove to be a great deterrent. It would certainly prove to be less disruptive to rhino behaviour compared to dehorning, in which rhinos' horns are removed to deter poaching.

QUESTION 2: Discuss the potential applications of mRNA technology beyond COVID-19, with reference to its role in tackling emerging infectious diseases.
Note: This is not a model answer. It only provides you with thought process which you may incorporate into the answers.
Introduction:
— Vaccines train our immune system to respond to pathogens. For instance, traditional vaccines use inactive or weakened versions of a virus to get the immune system to recognise the virus, and create tools to fight it. mRNA vaccines, on the other hand, give instructions to the body to produce a fragment of a virus, which then kickstarts the immune response.
— The biggest benefit of mRNA vaccines is that they can be developed within months and quickly altered as the virus changes, unlike traditional vaccines that can take years to develop and test.
Body:
You may incorporate some of the following points in your answer:
Potential applications of mRNA technology
— mRNA therapies have emerged as a promising platform for treating a variety of diseases, including cancer, infections, genetic disorders, and autoimmune diseases.
— The significance of mRNA vaccine technology extends beyond treating infectious diseases. For example, US researchers are attempting to employ the technique to treat skin and colon malignancies.
— Researchers are now investigating mRNA vaccines for other diseases such as Lyme disease, dengue fever, and HIV.
— Recent developments in delivery technologies and RNA stabilisation have increased the efficacy of mRNA vaccines against viral infections.
Conclusion:
— mRNA therapies use the host's cellular machinery to create target proteins, allowing for extremely targeted and customisable treatments. In the case of cancer, mRNA vaccines that stimulate immune responses against tumor-specific antigens are being developed on a personalised basis.

Prepare for infectious bird flu virus variant
Researchers from the Indian Institute of Science's department of biochemistry have cautioned about a new threat on the horizon that requires urgent attention from the central and state health authorities. They have discovered that the currently circulating and dominant 2.3.4.4b variant of the H5N1 avian influenza virus has undergone genomic mutations that significantly increase the threat of humans getting infected with bird flu. It poses the threat of an outbreak that could be much more challenging to prevent or manage than the Covid pandemic. The IISc team analysed 7,000 protein sequences of the 2.3.4.4b H5N1 variant found in birds, 820 sequences from non-human mammals, and 35,000 human H1N1 (swine flu virus) and H3N2 (seasonal influenza virus) sequences. They identified rapidly changing amino acids in the sequences, used multiple tools to identify similar regions in various proteins, constructed an evolutionary trend to understand how the viral species diverged from their common ancestor over time, and detailed specific variations in all the proteins of H5N1 infecting non-human mammals and humans to conclude that the 2.3.4.4b variant is much more harmful to humans than its predecessors.

ADHD Medicines Reduce Suicide, Crime Risks In Sweeping Study
Drugs to treat attention deficit hyperactivity disorder were linked to a reduced risk of suicidal behavior, substance misuse and criminality in the first research of its kind. The findings come amid increasing debate around whether ADHD is being over-diagnosed and therefore over-treated with drugs like Ritalin. The research published in the British Medical Journal on Wednesday did not investigate whether patients are being accurately diagnosed, but it does provide evidence supporting medical treatment. ADHD is characterized by difficulties with concentration and impulse control. Roughly 5% of children and 2.5% of adults are estimated to have the condition, which is also associated with an increased risk of substance misuse and self-harm. The researchers wanted to test whether the risk changed with medication. The study design was meant to closely mirror a randomized clinical trial, considered the gold standard of research. The scientists looked at health registry data from almost 150,000 patients newly diagnosed with ADHD in Sweden. At a two-year follow-up, they found that patients taking medicine had a 17% reduction in suicidal behavior and a 15% drop in substance misuse. They also found declines in the risk for criminality and transport accidents. When looking at the recurrence of these behaviors, there were also benefits linked to the medication. While the trial cannot show direct causation and could be confounded by factors such as ADHD severity, it provides doctors with vital evidence showing that drugs can address and reduce important risks, according to one of the authors. "These data should inform clinical guidelines, policies and current debates," said Samuele Cortese, a professor of child and adolescent psychiatry at the University of Southampton. The benefit was greater for patients taking stimulant medications than non-stimulants in the study. Stimulants include drugs like Novartis AG's Ritalin, while non-stimulants include Eli Lilly & Co.'s Strattera. The study results echo other similar conclusions, but "the large sample size, use of a national registry, and more sophisticated analysis give greater confidence in these results that findings aren't explained by something else other than medication use," said Adam Guastella, a clinical psychologist who works at Sydney Children's Hospital at Westmead and the University of Sydney's Brain and Mind Center. He was not involved in the research. Prescriptions in England for ADHD medicines have increased 18% year on year since the Covid-19 pandemic, according to research published in the BMJ Mental Health this year. The surge is believed to be linked to greater awareness of the condition.
