  The India BioEconomy Report was released recently by the Department of Biotechnology. It revealed that, in 2024, bioeconomy was valued at over $165 billion, contributing more than 4.2% to the national GDP. The Department of Biotechnology anticipates growth to $300 billion by 2030 and $1 trillion by 2047. What is Bioeconomy? Bioeconomy refers to the economic activities that utilise biological resources. This includes plants, animals, and microorganisms. It also encompasses the replication of natural processes for producing goods and services. The focus is on sustainability and renewable resources. Current State of the Bioeconomy India’s bioeconomy has nearly doubled in five years. It grew from approximately $86 billion in 2020 to $165 billion in 2024. The number of bioeconomy companies surged by 90%, reaching over 10,000. By 2030, this number is expected to double, potentially creating 35 million jobs. Sector Contributions The industrial sector is the largest contributor, generati...

  Tuberculosis (TB) remains global health challenge. Despite advances in medicine, it affects millions each year. TB is primarily caused by the bacterium Mycobacterium tuberculosis. It mainly targets the lungs but can also affect other organs. Types of Tuberculosis TB can be classified into two main types – pulmonary and extrapulmonary. Pulmonary TB affects the lungs and is the most common form. Extrapulmonary TB can impact other areas, such as the spine, brain, and kidneys. Miliary TB is a severe form that spreads throughout the body, causing various complications. Symptoms of Active Tuberculosis Active TB presents several symptoms. Common signs include a persistent cough lasting over two weeks, chest pain, fatigue, and weight loss. Patients may also experience fever, chills, and night sweats. In contrast, latent TB shows no symptoms, but individuals can still test positive. Transmission and Infection TB spreads through the air when an infected person coughs or sneezes. The bacte...

  Recently, France made breakthrough in clean energy with the discovery of a vast reserve of natural hydrogen in Folschviller, Moselle. This reserve is estimated to contain 46 million tons of “white hydrogen,” a naturally occurring gas that offers a sustainable alternative to traditional hydrogen production methods. What is White Hydrogen? White hydrogen is a naturally occurring form of hydrogen found in the Earth’s crust. Unlike other types of hydrogen, it requires no industrial production. This means it emits no carbon dioxide when used as fuel. White hydrogen is also known as natural, gold, or geologic hydrogen. Its discovery challenges the belief that hydrogen must be manufactured in laboratories. Advantages of White Hydrogen White hydrogen presents several advantages over grey, blue, and green hydrogen . It is environmentally friendly as it produces no CO₂ emissions. It is compatible with existing hydrogen infrastructure. Furthermore, it is cost-effective, estimated at $1 per ...

  The debate surrounding assisted dying has intensified following the death of renowned psychologist Daniel Kahneman in March 2024. Kahneman, a Nobel laureate, chose assisted suicide at a facility in Switzerland. His decision has reignited discussions about the ethics of assisted dying, particularly in light of his reflections on life and death. The topic is polarising, with strong opinions on both sides. The Concept of Assisted Dying Assisted dying refers to methods that help terminally ill patients end their lives to alleviate suffering. This practice is legal in a few countries, including Switzerland. The motivations for assisted dying often include unbearable pain, loss of dignity, and the desire for autonomy over one’s life choices. The ethical implications are high, raising questions about personal choice versus societal responsibility. Public Opinion on Assisted Dying Public sentiment on assisted dying varies widely. A recent Gallup survey indicated that 66% of Americans sup...

  Recent studies have reignited interest in how life began on Earth. Traditionally, the Miller-Urey hypothesis suggested that lightning strikes on primordial oceans created the necessary organic compounds for life. However, new research indicates that crashing waterfalls and breaking waves may have played important role in generating these compounds through a process involving water sprays. Miller-Urey Hypothesis The Miller-Urey experiment conducted in 1952 by Stanley Miller and Harold Urey is a mainstay of abiogenesis theory. They demonstrated that organic molecules could form from inorganic precursors when exposed to electrical energy. Their experiment simulated early Earth conditions, using a mixture of water, methane, ammonia, and hydrogen. The results yielded amino acids, essential building blocks of life. Despite its significance, the hypothesis faced criticism regarding the frequency and effectiveness of lightning strikes in real-world scenarios. New Findings on Water Spray...

  India has recently made strides in cancer treatment with the introduction of CAR T-cell therapy . The results from the first clinical trials have been published in The Lancet, showcasing a remarkable success rate. This therapy is a game changer for patients with blood cancers. It offers hope to those who have exhausted other treatment options. What is CAR T-Cell Therapy? CAR T-cell therapy, or chimeric antigen receptor T-cell therapy, is an innovative treatment that harnesses the body’s immune system. It trains T-cells to target and destroy cancer cells. This therapy is specifically designed for certain blood cancers. It is particularly beneficial for patients whose cancer has relapsed or failed to respond to standard treatments. Clinical Trial The clinical trials reported a response rate of nearly 73%. This indicates that number of patients benefited from the treatment. The trials also provided critical data on survival rates for patients with acute lymphoblastic leukaemia and l...

  Quantum biology , an emerging and highly advanced field, merges the microscopic world of quantum mechanics with the complexities of biology. It serves as a bridge between quantum physics and life sciences, revealing how quantum phenomena influence biological mechanisms in ways that were previously unimaginable. Quantum biology is a cutting-edge field that explores the role of quantum mechanics in biological systems, merging the principles of physics with the complexity of life. While traditional biology relies on classical physics and chemistry to explain life’s mechanisms, quantum biology suggests that fundamental quantum phenomena—such as superposition, entanglement, and tunneling—are at work in processes like photosynthesis, respiration, and even consciousness. For decades, quantum effects were thought to be relevant only at atomic and subatomic levels, but recent discoveries have shown that these principles can influence biological functions at macroscopic scales.
