What is Functional epidemiology?
- Epidemiology is the foundation science of public health.
- Disease surveillance and epidemiology are two sides of the same coin; the former provides real-time information for action and the latter analyses data and facilitates planning.
- During the COVID-19 pandemic, lack of functional epidemiology led to inadequate forward planning.
- India has good epidemiologists, but they use their expertise predominantly for research and teaching — it is high time they used this discipline for managing public health.
What is Dark Matter?
Know about Dark Matter
- All interactions in the universe are a result of four fundamental forces acting on particles — strong nuclear force, weak nuclear force, electromagnetic force and gravitation.
- Dark matter is made up of particles that do not have a charge — which means they do not interact through electromagnetic interactions.
- So, these are particles that are “dark”, namely because they do not emit light, which is an electromagnetic phenomenon, and “matter” because they possess mass like normal matter and hence interact through gravity.
- Gravitational force, besides not being fully integrated and understood by particle physicists, is extremely weak. For one thing, a particle that interacts so weakly becomes rather elusive to detect.
- This is because interactions from other known particles could drown out signals of dark matter particles.
How could scientists infer the presence of dark matter?
- Dark matter makes up around 85% of the matter in the known universe, but because it doesn’t interact with light it is practically invisible. Likewise, whatever the constituent particles of dark matter are, they don’t interact strongly with other matter either.
- In fact, the only way scientists can infer the presence of dark matter is via its gravitational influence which literally holds together most galaxies, preventing their constituent stars from flying apart as they spin.
What is the latest about Dark Matter?
The latest to hit the news in the field of dark matter is a dark matter detector experiment named LUX-ZEPLIN (LZ) in South Dakota in the U.S. As of today, this is the most sensitive dark matter detector in the world.
What are the powers of the CCPA?
Powers of the Central Consumer Protectipon Authority(CCPA)
- The CCPA has been established to regulate matters related to the violation of the rights of consumers.
- Under the Consumer Protection Act (CPA), 2019, the authority was established to regulate violations of consumer rights, unfair trade practices, and false or misleading advertisements that are prejudicial to the interest of the public.
- The CCPA has authority under section 18 of the CPA, 2019 to protect, promote and most importantly enforce the rights of the consumers and prevent violation of their rights under the Act.
- It also seeks to ensure that no person engages in unfair trade practices.
- It is also empowered to issue guidelines to enforce the rights of the consumers laid down in the Act.
- The authority has issued a letter to the Chief Secretaries of the States on service charge imposition, asking them to ensure compliance with the new guidelines on service charges.
- It has also been said that the State should instruct all the district magistrates to take appropriate action against violations of the guideline.
World Population
- According to a UN report the expected world population by November 15, 2022, will be 8 billion.
- The report said that India will surpass China as the most populous country by 2023.
- The overall population milestone is a reminder of our shared responsibility to care for our planet and a moment to reflect on where we still fall short of our commitments to one another.
- The forecast by the UN Dept of Economic and Social Affairs said that the world’s population is growing at its slowest pace since 1950.
